Inside MIT.nano – MIT News

On a recent evening, Cathrin Stickney stood marveling at the stillness of the custom-designed imaging suites in the underground level of MIT.nano the environmentally quietest space on campus. Laudably ultra-low vibrations, ultra-low electromagnetic interference, and acoustically silent. All in a building that, like most of the rest of MIT, sits on a century-old landfill built on swampland.

Its more than difficult to pull that off. Its architecturally amazing, Stickney, a successful entrepreneur and former architect, said. Equipped with a neon safety vest and clear safety glasses, Stickney was on site to learn more about a building that embodies one of the largest research investments in MIT history.

The leaders of MIT.nano pulled out all the stops during the first-ever tour of the 214,000 gross-square-foot research facility taking shape in the heart of MIT campus, just steps from the Infinite Corridor. The tightly choreographed public viewing involved safely navigating 60 guests, mostly members of the MIT Corporation, through what is still an active construction site.

Nanoscience and nanotechnology are driving some of the most important innovations today, in health care, energy, computing almost every field of engineering and science. A facility that allows MIT faculty and students to play a role in these coming changes is of the Institutes highest priority, says President L. Rafael Reif, who was along for the tour. As he has said: Even big problems have answers if you have your hands on the right tools.

As the tour group convened in a conference room near where they would access the site, the projects faculty lead, Vladimir Bulovi, fine-tuned that sentiment. The toolset we need to bring forward the next generation of ideas is a nano toolset, and with those words Bulovi and his team launched the first public showing of MIT.nano.

The sneak peek

Starting in the MIT.nano subterranean level, Stickney and husband Mark Gorenberg 76, a venture capitalist, took in the cavernous space. The imaging suites are set on what Dennis Grimard, the buildings operations director, calls The Inertia Slab a structure that complements the location of MIT.nano, and makes it the quietest spot on campus. The slab is a block made of 3.2 million pounds of concrete poured onto 400,000 pounds of epoxy-coated rebar. Its creation required approximately more than 100 cement trucks operated continuously in a single day from 4 a.m. to 4 p.m.

With hands clasped, the couple listened attentively as Thomas Schwartz, a biology professor, spoke about the scope of research MIT.nano will enable. The extreme shielding from environmental noise, he said, will satisfy the challenging low-vibration demands of high-end electron microscopes, particularly those for biological imaging. His delight was palpable. These new microscopes will allow us to visualize large protein complexes at atomic resolution, and to observe thin sections of entire cells in nanometer precision, said Schwartz, the Boris Magasanik Professor of Biology. This truly represents a quantum leap for structural and cell biology!

On the construction elevator, jolting from the basement to the first floor, Stickney said: The massive amount of effort put into all of this is stunning. Shouting above the wind, Gorenberg agreed. It makes sense from an investment standpoint, he remarked. Nanotechnology cuts across all disciplines, so its going to be vital to everyone.

The clean rooms

The hoist clanged to a stop, and the group exited to check out state-of-the-art clean rooms. Waiting for them was Luis Velsquez-Garca, a principal research scientist in the Microsystems Technology Laboratories, and an expert in micro- and nanofabrication technologies. Outfitted in a white jumpsuit, he quickly launched into a description of how MIT.nano will open new worlds for researchers. The clean room will be like a hive, he said, bustling with people working together to make breakthroughs in nanotechnology. It will enable: devices that can produce X-rays for medical imaging, nanosatellite propulsion, and plasma diagnostics. He described a future in which nanotechnology-enabled materials dramatically change 3-D-printing technology.

Tour guests checked out the clean rooms on the third level, too, where sunlight pours through glass in hallways that overlook the MIT dome and new courtyard below. Krystyn Van Vliet, a professor of materials science and engineering and biological engineering, described how clean rooms will provide a precisely controlled environment with low levels of dust, airborne microbes, aerosol particles, chemical vapors, and anything else that can get in the way of their work. Van Vliet, the Michael (1949) and Sonja Koerner Professor of Materials Science and Engineering, studies material behavior at the interface of mechanics, chemistry, physics, and biology. She informed tour guests that the facility will connect MIT experts in materials synthesis, characterization, and teaching for a range of applications, and build on the inspiration of interdisciplinary collaborators such as the late Institute Professor Emerita of Physics and Electrical Engineering and Computer Science Mildred Dresselhaus.

Van Vliet, the director of manufacturing innovation for the MIT Innovation Initiative, also said MIT.nano is poised to support an innovation community that will help usher in next-generation manufacturing processes and training approaches for production of electronics, photonics, fibers, and biopharmaceuticals. For instance, the facility will benefit academic and industry partnerships for MIT researchers who participate in Manufacturing USA Institutes, a network of public-private partnerships between government, industry, and academia focused on de-risking and prototyping new manufacturing capabilities to speed adoption by U.S. manufacturers.

Throughout the building, MIT faculty were working hard to convey their excitement. Academics were situated on every level, and even the guides escorting guests through the building were impressively credentialed: Anuradha Agarwal, a principal research scientist at the Microphotonics Center who develops miniaturized chemical sensors; Polina Anikeeva, the Class of 1942 Career Development Professor in the Department of Materials Science and Engineering who stimulates brain activity using nanotechnologies; electrical engineering professors Karl Berggren, who specializes in nanofab and quantum devices, and Rajeev Ram, who develops novel photonics and electronics; and William Tisdale, the Charles and Hilda Roddey Career Development Professor in Chemical Engineering, who explores use of colloidal quantum dots and 2-D materials in next-generation renewable energy technologies. All the stops, pulled.

A game-changer

MIT.nano is designed as an invitation to the community. With 53,000 square-feet of glass on its exterior surface, the new building may be surrounded on all sides by other buildings, but its appearance and effect are transparency. As Grimard explains, Typically, MIT buildings have windowed offices along the outside and labs get placed on the inside. We did just the opposite. We wanted the MIT community to see inside and have that connectivity with the space. This is everyones building.

Prepared to serve more than 2,000 researchers from across campus, MIT.nano will be transformative. An interior building set in the footprint of the former Building 12, its broader visibility will rely greatly on the research collaborations forged within its walls. Those connections hold the power to reimagine MIT.

The wrap-up

The guests finished by touring the upper levels of MIT.nano. On the fifth floor, which is dedicated to prototyping maker spaces and teaching labs, presenter Brian Anthony, director of MITs Master of Engineering and Manufacturing Program, told guests MIT.nano will become a central resource for creating disruptive technologies. Researchers will gain the ability to distinguish and manipulate materials at the atomic scale, create devices using those materials, and develop ways of implementing those devices within larger systems. MIT.nano is not owned by any one area of MIT, he said. Or put simply, added Anthony: MIT.nano is like an iPhone and researchers across campus are welcome to make the apps.

Nodding as he listened, John Chisholm 75, SM 76, a serial entrepreneur, commented: You can see how many disciplines meet here, he said. This is the future of research and education: conventional boundaries among schools and departments are disappearing.”

Chisholm and the other guests piled back into the hoist, which came to its final stop: the mechanical penthouse, where MIT.nanos senior project manager Travis Wanat awaited. Wanat is a true believer in the promise of MIT.nano. He met with 35 labs, centers, and departments mainly abutters to the site to allay concerns from the start. Not an easy task when simply pouring the foundation involved the removal of 1.4 million cubic feet of dirt. Now the project, which Bulovi refers to as a dream nearing reality, is finally at least briefly on public display. Wanat eagerly detailed the construction process and took a barrage of questions about prefabrication strategy, metrics for overall savings, the early procurement process, and more.

Satisfied with the detailed answers, the Corporation members descended by stairs to the unfinished courtyard below. They held metal handrails rather than wooden ones, warned earlier of splinters. They spoke of the building design particularly the energy conservation strategies with approval.

The building is amazingly larger than any of us could have imagined, said Gorenberg. Alan Spoon 73, a venture capitalist, added: The opportunity for students and researchers to be rubbing shoulders in the most productive way imaginable is mind blowing. Trailing behind for a final look, the granddaughters of Dresselhaus, a beloved scientist, described weekly lunches during which Dresselhaus would pull them to a window from where they would observe construction progress. She was so excited about the MIT.nano building, said Leora Cooper. She loved it and the future it brings.

INVESTING IN THE U

The University of Minnesota has been in the news recently for its cutting-edge research everything from nano-technology sponges to protect our water supply to tackling substance abuse. In addition to the great research work that is being done at the U of M, I wanted to call attention to its critical role of building our workforce for the future. I work for a medium-size Minnesota company that has grown dramatically over the last 10 years. We need a talented workforce to continue to grow and thrive. We continuously seek to hire strong and prepared college graduates who have backgrounds in K-12 education and information technology. My company and many other local companies depend on the state of Minnesota investing in the university to prepare our future workforce.

Currently, the U of M is requesting state funding to invest in the success of Minnesotas students. State funding will help improve graduation rates, reduce undergraduate debt, improve academic experiences and perhaps most importantly produce more Science, Technology, Engineering and Mathematics (STEM) degree graduates.

Currently, the U of Ms STEM departments are under great pressure, as increasing numbers of highly qualified students compete to enroll in programs that are full to the brim. At the same time, Minnesota companies are struggling to find the information technology and other STEM employees they need. State funding can help expand those programs. In turn, investing in these programs will supply Minnesota companies with a talented and skilled workforce that our state needs to compete advancing our competitive edge nationally and internationally. I am just one of 24,796 alumni who live in Dakota County, and one of more than 550,000 alumni from the university system. We contribute to a thriving Minnesota every day. I strongly urge the Legislature to support the universitys request for funding for student success that will help our state respond to our significant workforce needs.

President Trumps 2018 budget includes the elimination of the Corporation for National and Community Service. Eliminating CNCS and its core programs, including AmeriCorps and Senior Corps, would have a crippling impact on our community, devastating local organizations that leverage AmeriCorps and Senior Corps funding to engage citizens in service and to cultivate matching support from non-federal sources.

National service programs not only provide vital services to local residents here in St. Paul but also provide a pathway to employment for young Americans. Through their service, AmeriCorps members gain skills and experience, develop professional networks and earn an education award that can reduce the cost of college. I serve as a proud board member of the Minnesota Alliance With Youth, a statewide organization that supports AmeriCorps Promise Fellows and AmeriCorps VISTAs. In Congresswoman Betty McCollums district, 49 Promise Fellows are supporting 1,470 students. Last year, 91 percent of the students served increased their academic engagement.

AmeriCorps and Senior Corps have a history of bipartisan support. I am counting on Congresswoman McCollum and other members of Congress to continue that legacy of support for this cost-effective, results-driven resource for our community.

Strength of hair inspires new materials for body armor – ScienceBlog.com (blog)

In a new study, researchers at the University of California San Diego investigate why hair is incredibly strong and resistant to breaking. The findings could lead to the development of new materials for body armor and help cosmetic manufacturers create better hair care products.

Hair has a strength to weight ratio comparable to steel. It can be stretched up to one and a half times its original length before breaking. We wanted to understand the mechanism behind this extraordinary property, said Yang (Daniel) Yu, a nanoengineering Ph.D. student at UC San Diego and the first author of the study.

Nature creates a variety of interesting materials and architectures in very ingenious ways. Were interested in understanding the correlation between the structure and the properties of biological materials to develop synthetic materials and designs based on nature that have better performance than existing ones, said Marc Meyers, a professor of mechanical engineering at the UC San Diego Jacobs School of Engineering and the lead author of the study.

In a study published online in Dec. in the journal Materials Science and Engineering C, researchers examined at the nanoscale level how a strand of human hair behaves when it is deformed, or stretched. The team found that hair behaves differently depending on how fast or slow it is stretched. The faster hair is stretched, the stronger it is. Think of a highly viscous substance like honey, Meyers explained. If you deform it fast it becomes stiff, but if you deform it slowly it readily pours.

Hair consists of two main parts the cortex, which is made up of parallel fibrils, and the matrix, which has an amorphous (random) structure. The matrix is sensitive to the speed at which hair is deformed, while the cortex is not. The combination of these two components, Yu explained, is what gives hair the ability to withstand high stress and strain.

And as hair is stretched, its structure changes in a particular way. At the nanoscale, the cortex fibrils in hair are each made up of thousands of coiled spiral-shaped chains of molecules called alpha helix chains. As hair is deformed, the alpha helix chains uncoil and become pleated sheet structures known as beta sheets. This structural change allows hair to handle up a large amount deformation without breaking.

This structural transformation is partially reversible. When hair is stretched under a small amount of strain, it can recover its original shape. Stretch it further, the structural transformation becomes irreversible. This is the first time evidence for this transformation has been discovered, Yu said.

Hair is such a common material with many fascinating properties, said Bin Wang, a UC San Diego PhD alumna and co-author on the paper. Wang is now at the Shenzhen Institutes of Advanced Technology in China continuing research on hair.

The team also conducted stretching tests on hair at different humidity levels and temperatures. At higher humidity levels, hair can withstand up to 70 to 80 percent deformation before breaking. Water essentially softens hair it enters the matrix and breaks the sulfur bonds connecting the filaments inside a strand of hair. Researchers also found that hair starts to undergo permanent damage at 60 degrees Celsius (140 degrees Fahrenheit). Beyond this temperature, hair breaks faster at lower stress and strain.

Since I was a child I always wondered why hair is so strong. Now I know why, said Wen Yang, a former postdoctoral researcher in Meyers research group and co-author on the paper.

The team is currently conducting further studies on the effects of water on the properties of human hair. Moving forward, the team is investigating the detailed mechanism of how washing hair causes it to return to its original shape.

Tatas Learn Key Lesson As Nano Heads For Sunset: Indians Want … – Swarajya

After eight years and a sustained failure to set hearts racing, the Tata Nano, it seems, is set to drive into the sunset. A Times of India report says that Tata Motors will phase out the Nano in three to four years so that it can cut out the multiplicity of car platforms from the current six to just two.

If this happens, it will be both a vindication of ousted Tata Sons chairman Cyrus Mistry, and a partial rejection of his stand that the Nano was being kept alive only for emotional reasons. His reference was to the fact that the Nano was Ratan Tatas pet Rs 1 lakh car project, a car which was supposed to upgrade millions from thinking two-wheelers to four-wheelers.

A day after he was ousted, Mistry said in a note leaked to the media that the Nano had consistently lost money, peaking at Rs 1,000 crore As there is no line of profitability for the Nano; any turnaround strategy for the company (Tata Motors) requires to shut it down. Emotional reasons alone have kept us away from this crucial decision.

But he has been proved wrong in his assumption that emotional reasons will keep the Nano running, as the decision by the Tata Motors management to phase it out along with the Sumo show.

The failure of the Nano, unveiled with much fanfare amidst global spotlight, can primarily be put down to Tatas mistake in presuming that price was crucial to weaning people away from two-wheelers to cheap cars.

This is a mistake many marketers make: they confuse the average Indians need for affordability to a willingness to buy products that come cheap.

Far from it. As Dheeraj Sinha wrote in his book India Reloaded, the average Indians idea of a car was built around the roomy Ambassador. He may not be able to afford a car, but his idea of a car is not something with all the essentials removed from it. Quite the contrary. He want the addition of desirable features. A car is a status enhancer, and the last thing Indians want is to look cheap. A second-hand car that is cheaper than the Nano would work for most Indians better than a car that has cheap written all over it. The Nano was tomtommed as the worlds cheapest car, and so the Indian lumped it.

Consider the contrast with Renaults Kwid, another car inspired by the idea of frugal engineering. Far from looking cheap, it tries to resemble a mini SUV. And, after selling over 100,000 Kwids, Renault is making money on it.

Phasing the Nano out shows that Ratan Tata has learnt to bite the bullet. The new Tata cars, built around style and better performance, are doing much better than the old models.

Tata Motors has outgrown Nano thinking.

Bendable Phone Advances With New Flexible, Ultrafast Memory – Android Headlines

The University of Exeter has been working on new multilevel, flexible, ultrafast memory devices, and this would be a significant advance in the development of devices such as bendable phones, televisions, and even smart clothing. Engineering talents have detailed small but high-capacity memories that will be ideal for flexible devices including smartphones. Additionally, these new transparent memory devices will be both eco-friendly and cheap to produce, so could be a credible and more affordable to flash memory that is currently used in graphics cards, memory cards, and USB drives.

Research about this endeavor has been published in ACS Nano, a scientific journal. The new development regards a nano-scale, non-volatile fusion of graphene oxide and titanium oxide, and the team behind the new memory devices suggest that it signifies an evolution for flexible electronics with improved power, speed, and endurance. Lead author of the research paper, Professor David Wright, described the new GO-based memory option. Its capable of being written to and read from in less than five nanoseconds and is just eight nanometers thick and 50 nanometers long. When discussing the results the research paper says it will help transform the way in which we view the potential and possibilities for GO memory device development and applications. In the event that this type of new memory could be produced in high enough yields, it could mean the end of flash memory in electronic devices.

Its not the first time graphene oxide has been used in the production of memory devices. However, previously the results had been slow and cumbersome, and thus more suited to the economy end of the device market. The research is in the early stages and it could be quite some time before the ultra fast, flexible memory is ready for mass production. In recent years many smartphone companies including LG, Microsoft, and Samsung have invested resources into flexible devices, and these and other manufacturers are likely to be following further developments involving flexible memory very closely. As far as the much-rumored Samsung Galaxy X foldable phone is concerned, it was previously thought that production might begin in Q3 or Q4 this year. However, recent news inferred there were production and technical issues, and that the companys first foldable smartphone launch is more likely to occur next year.

CVTC Manufacturing Show showcases opportunities, technology – Leader-Telegram

Cole Hill knows what he wants to do in a future career.

I want to build motors V-8s probably, said the Colfax High School junior who spends time racing at the Red Cedar and Jim Falls tracks.

But just what does one study to prepare to build big engines? Hunter Sullivan of Chippewa Falls, a Chippewa Valley Technical College machine tooling technics student, had some ideas for him at CVTCs annual Manufacturing Show on March 2.

He told me about their CNC (computerized numerical control) machines and the careers, said Hill, who thinks he will eventually enroll at CVTC but he is unsure which program he will choose. I havent looked at any other places.

Introducing people like Hill to careers in manufacturing is a big part of CVTCs Manufacturing Show, which attracted about 1,600 people to CVTCs Manufacturing Education Center. Wonders of modern manufacturing were displayed and demonstrated in CVTC programs, including automation engineering technology, industrial mechanical, machine tooling technics, welding/welding fabrication and manufacturing, nano and industrial engineering programs.

About 40 manufacturing companies were also represented, with display tables highlighting their products and job opportunities.

Sullivan, a 2015 Chippewa Falls Senior High School graduate, connected with Hill as another young man who likes to work with his hands. I just like making things, Sullivan said. I took shop classes in high school with manual lathes and I thought that was pretty cool. But what I learn here is way more than they teach you in high school.

Sullivan is already working in manufacturing, doing some part-time laser cutting work at Riverside Machine. Im not doing CNC work, but hopefully when I finish school they will keep me on as a machinist, he said.

Visitors to the Manufacturing Show were able to take part in hands-on activities, such as trying their hand at welding, building a tiny flashlight with the help of manufacturing engineering technologist students, or playing with projects like a billiards game made by automation engineering technology students.

This is an opportunity to show off new technology, said CVTC dean of manufacturing Jeff Sullivan. The Manufacturing Show brings together alumni and people in the area, and shows off student projects. Our manufacturing partners come in and show the things theyre doing.

More opportunity

Several area high schools sent bus loads of students to the event. They toured local manufacturing companies prior to the show. Other students came on their own, or with their parents.

Menomonie resident Tim Frank, a CVTC graduate, attended the event with his wife and son, Nathan.

Hes interested in coming here next year, Frank said of his son. Hes working at a machine shop in Menomonie after school now. He saw this show was available and asked to come.

I really havent decided what program to take, Nathan Frank said. But it will probably be something in the machining area. Its making stuff. Its hands-on.

Dawn Schrankler and her husband brought their daughter, Kelsey, from Neillsville to the show. Were trying to get her interested in more of a selection, said Schrankler. She wants to be a veterinarian assistant, but were trying to broaden her horizons and open her eyes to other areas.

Not all of the people attending the show to explore careers were high school students or even recent high school graduates. Some seeking to change careers found plenty of older CVTC students who have followed a similar path.

This program is fantastic, said Casey Schellhorn, an student in CVTCs automation engineering technology program who graduated from River Falls High School in 2010. I wanted more opportunity than I had working in food service. I was looking for something interesting and found this on the CVTC website.

Schellhorn was stationed where he could explain to visitors how to play a miniature billiards game and also the pneumatics, electronics and sensors that made the game work. Other students were at the event to explain what they do, what they are learning, and the exciting opportunities available to them in manufacturing careers.

Stretchy electrode paves way for flexible electronics | Stanford News – Stanford University News

The brain is soft and electronics are stiff, which can make combining the two challenging, such as when neuroscientists implant electrodes to measure brain activity and perhaps deliver tiny jolts of electricity for pain relief or other purposes.

Go to the web site to view the video.

A robotic test instrument stretches over a curved surface a nearly transparent, flexible electrode based on a special plastic developed in the lab of Stanford chemical engineer Zhenan Bao.

Chemical engineer Zhenan Bao is trying to change that. For more than a decade, her lab has been working to make electronics soft and flexible so that they feel and operate almost like a second skin. Along the way, the team has started to focus on making brittle plastics that can conduct electricity more elastic.

Now in Science Advances, Baos team describes how they took one such brittle plastic and modified it chemically to make it as bendable as a rubber band, while slightly enhancing its electrical conductivity. The result is a soft, flexible electrode that is compatible with our supple and sensitive nerves.

This flexible electrode opens up many new, exciting possibilities down the road for brain interfaces and other implantable electronics, said Bao, a professor of chemical engineering. Here, we have a new material with uncompromised electrical performance and high stretchability.

The material is still a laboratory prototype, but the team hopes to develop it as part of their long-term focus on creating flexible materials that interface with the human body.

Electrodes are fundamental to electronics. Conducting electricity, these wires carry back and forth signals that allow different components in a device to work together. In our brains, special thread-like fibers called axons play a similar role, transmitting electric impulses between neurons. Baos stretchable plastic is designed to make a more seamless connection between the stiff world of electronics and the flexible organic electrodes in our bodies.

One thing about the human brain that a lot of people dont know is that it changes volume throughout the day, says postdoctoral research fellow Yue Wang, the first author on the paper. It swells and deswells. The current generation of electronic implants cant stretch and contract with the brain and make it complicated to maintain a good connection.

If we have an electrode with a similar softness as the brain, it will form a better interface, said Wang.

To create this flexible electrode, the researchers began with a plastic that had two essential qualities: high conductivity and biocompatibility, meaning that it could be safely brought into contact with the human body. But this plastic had a shortcoming: It was very brittle. Stretching it even 5 percent would break it.

As Bao and her team sought to preserve conductivity while adding flexibility, they worked with scientists at the SLAC National Accelerator Laboratory to use a special type of X-ray to study this material at the molecular level. All plastics are polymers; that is, chains of molecules strung together like beads. The plastic in this experiment was actually made up of two different polymers that were tightly wound together. One was the electrical conductor. The other polymer was essential to the process of making the plastic. When these two polymers combined they created a plastic that was like a string of brittle, sphere-like structures. It was conductive, but not flexible.

The researchers hypothesized that if they could find the right molecular additive to separate these two tightly wound polymers, they could prevent this crystallization and give the plastic more stretch. But they had to be careful adding material to a conductor usually weakens its ability to transmit electrical signals.

After testing more than 20 different molecular additives, they finally found one that did the trick. It was a molecule similar to the sort of additives used to thicken soups in industrial kitchens. This additive transformed the plastics chunky and brittle molecular structure into a fishnet pattern with holes in the strands to allow the material to stretch and deform. When they tested their new materials elasticity, they were delighted to find that it became slightly more conductive when stretched to twice its original length. The plastic remained very conductive even when stretched 800 percent its original length.

We thought that if we add insulating material, we would get really poor conductivity, especially when we added so much, said Bao. But thanks to their precise understanding of how to tune the molecular assembly, the researchers got the best of both worlds: the highest possible conductivity for the plastic while at the same transforming it into a very robust and stretchy substance.

By understanding the interaction at the molecular level, we can develop electronics that are soft and stretchy like skin, while remaining conductive, Wang says.

UAE students launch first nano satellite into space – Arab News

The Mohammed bin Rashid Space Center (MBRSC) and the American University of Sharjah (AUS) have announced the successful launch of Nayif-1, the United Arab Emirates (UAE) first nano satellite launched into space. Nayif-1 takes on added importance as an educational project with the goal of providing hands-on experience to Emirati engineering students on designing, building, testing and operating nano satellites. The launch was a step toward the implementing of the Mars 2117 Project. The Nayif-1s mission aims to send and receive text messages on amateur radio frequencies. The project objectives include characterizing and validating the accuracy of a thermal model of Nayif-1 with in-situ temperature measurements in space, as well as determining the evolution of the solar cells performance in space. The nano satellite was launched from Satish Dhawan Space Center in India. The ground station, located at the AUS, received the first signal from Nayif-1, 18 minutes and 32 seconds after it reached its orbit. A team of engineers and students were present at the ground station during launch. Nayif-1 will be operated and controlled from the ground station at AUS moving forward. Speaking on this occasion, Bjorn Kjerfve, chancellor of the AUS, said: The AUS is an institution dedicated to the pursuit of excellence in academia and research. The successful launch of Nayif-1 is a reflection of that vision and a proud moment for the AUS, considering the important part played in its development by seven Emirati students from the AUS. The nano satellite will be monitored by the ground station based at AUS. We are very pleased to have developed this project with MBRSC and look forward to future collaborations that will advance the skills and knowledge of AUS Emirati engineers in space technologies. Kjerfve said: We are proud of our students role in the development of the satellite and their participation in completing all the phases of the space program. This is a living example of our strategy to move toward a knowledge-based economy, to promote innovation in the region, and serve the post-oil needs of the GCC countries. Commenting on the launch, Fatma Lootah, deputy project manager of Nayif-1, said: Through the ground station at the AUS, we will continue to monitor the satellite to understand how it responds to commands in the daytime and in the evening; however it will be shifted later on to the autonomous mode. We will also verify the active control system board in Nayif-1, which determines the satellites direction and maintains its balance.

Phonon nanoengineering: Vibrations of nanoislands dissipate heat more effectively – Phys.Org

March 8, 2017 The nanoislands are completely isolated (left) or adjoining each other (right). Credit: IFJ PAN

Europium silicide has for some time attracted the attention of scientists. Recognized as being promising for electronics and spintronics, this material has recently been submitted by a team of physicists from Poland, Germany and France to comprehensive studies of the vibrations of its crystal lattice. The results yielded a surprise: deposited on a substrate of silicon, some structures of europium silicide appear to vibrate in a way that clearly broadens the possibilities of designing nanomaterials with tailored thermal properties.

The vibrations of atoms in the crystal lattices of materials, known as phonons, are not chaotic. Instead, they are governed by the lattice symmetry, atomic mass and other factors. For instance, the atoms deep in the solid oscillate differently than on its surface, and still differently when the material forms, for example, nanoislands i.e. small atomic clusters on a substrate. An international team of physicists, composed of scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow, the Karlsruhe Institute of Technology (KIT) and the European Synchrotron (ESRF) in Grenoble, have for the first time comprehensively examined how the vibrations of the crystal lattice of europium silicide (EuSi2) change depending upon the nanostructures arrangement on a substrate of silicon. The study yielded remarkable results: a new type of vibration was observed in the sample in which the EuSi2 nanoislands were in contact with each other.

“Usually nanoengineering means modifying material on a scale of nanometres, or billionths of a metre. The research on europium silicide in which we participated allows us to offer something more: phonon nanoengineering, i.e. engineering in which not so much the structure of the material is carefully designed as the vibrations of atoms in its crystal lattice,” says Dr. Przemyslaw Piekarz (IFJ PAN).

Europium silicide forms a crystal, in which each europium atom is surrounded by 12 silicon atoms. The system exhibits what is known as tetragonal symmetry: the distance between atoms in one direction is different than in the two remaining directions. This metallic compound readily binds to silicon, and also has a record-breakingly low so-called Schottky barrier (i.e. the barrier of potential energy electrons encounter on their transition from the metal to silicon). Such materials are of interest today in view of their potential application in nanoelectronic systems, for example, in MOSFET technology used in the production of modern processors. However, at low temperatures EuSi2 also exhibits interesting magnetic properties, which makes it attractive for the successor of electronics – spintronics.

Although compounds of rare earth metals and silicon play a fundamental role in heat transport, among others, their lattice vibrations have not to date been comprehensively studied. Meanwhile, in nanoelectronic systems where heat is generated in large amounts, thermal properties of a material became as important as the magnetic or electric properties.

A group led by Dr. Svetoslav Stankov (KIT, Germany) has developed a procedure for the preparation of epitaxial EuSi2 nanostructures by depositing, in ultrahigh vacuum conditions, small amounts of europium atoms on a heated substrate of single crystalline silicon. Moreover, by careful adjustment of the temperature of the substrate and the amount of europium atoms they were able to tailor the morphology of the prepared EuSi2 nanostructures on the silicon surface.

“In this experiment we focused our attention on four europium silicide samples forming: a uniform film, which could be regarded as a solid crystal, a tightly pleated film, and two different assemblies of nanoislands,” explains Dr. Stankov and adds: “A nanoisland is a discrete cluster of self-organized atoms on a surface reaching sizes of several tens of nanometres with a height of a dozen or so nanometres. It turned out that especially interesting are the samples in which the EuSi2 nanoislands are completely isolated from each other and those where the nanoislands are in close contact with each other.”

The samples were prepared in the ultra-high vacuum system at the nuclear resonance beamline of the ESRF synchrotron in Grenoble by the KIT group and investigated in situ by nuclear inelastic scattering (NIS).

“NIS is a state-of-the-art method for direct measurement of the energy spectrum of atomic vibrations of nanomaterials with very high resolution. In this experimental technique the sample is illuminated with high energy photons, selected so that their absorption by atomic nuclei excites or annihilates lattice vibrations of a certain kind, yielding the element-specific phonon density of states,” adds Dr. Stankov.

Theoretical studies at the IFJ PAN were carried out ab initio, based on the fundamental laws of quantum mechanics and statistical physics, using PHONON software written by Prof. Krzysztof Parlinski (IFJ PAN). The Cracow group dealt not only with modelling the vibrations of the crystal lattice of structures of europium silicide, but also determining the conditions for conducting experiments in the ESRF synchrotron.

“In Grenoble only the vibration energies of europium atoms were recorded. The curves obtained from the measurements agreed very well with our calculations for the solid crystal and the surface. We could supplement these data with our predictions for the movements of silicon atoms, which helped to better interpret the results,” says Prof. Parlinski.

Particularly interesting results were obtained for the samples with nanoislands. In the case of a substrate coated with discrete nanoislands a significant increase of the amplitude of vibration of europium atoms was observed, up to 70% relative to the vibrations in the crystal. Such a large increase translates into significantly greater possibilities in the field of heat transfer. The most interesting effect appeared, however, in the sample with nanoislands adjoining each other. Namely, additional vibrations with a characteristic energy were found at the interfaces between the nanoislands. Although theoretically predicted earlier on, their existence was confirmed experimentally for the first time. They constitute another ‘gateway’ through which material can discharge heat into the environment. By means of the adjoining nanoislands a significant increase in the efficiency of heat transfer in nanostructures becomes a reality.

“In the analysis of materials scientists usually look at the properties of a sample of fixed morphology. We have described a whole spectrum of possible surface morphologies of EuSi2. An advanced theoretical model and precise measurements have allowed us for the first time to exactly trace how the vibrations of the crystal lattice of a nanomaterial change depending on its arrangement on the substrate,” stressed Dr. Piekarz.

The research on europium silicide nanostructures, funded by the Helmholtz Association, the Karlsruhe Institute of Technology (project VH-NG-625) and on the Polish side by the HARMONIA grant from the Polish National Science Centre, is of a basic nature. However, the knowledge gained, especially with regard to the crystal lattice vibrations occurring at the interface between adjacent nanoislands and the related drastic changes in the heat transport, is universal. After suitable adaptation, this phenomenon will allow researchers to design nanomaterials other than europium silicide with tailored thermal properties.

Ratan Tata’s dream project Nano contributed to Renault’s success, says CEO – Business Standard

Kwid has put Renault on strong foot in India, said Ghosn

Carlos Ghosn, chairman and CEO of French auto maker Renault has said that Renault has started making money in India after selling 1,00,000 Kwids. Kwid is a compact hatch-back built on the sketch of cars such as Tata Nano and Maruti Suzuki Alto. The Renault Kwid is a second car, after Duster, from the stable of Renault to achieve this milestone. Duster’s total sales in India has crossed over 1.50 lakh units. Since its launch, Kwid sales crossed 1.30 lakh units. Last month the company had sold around 9,600 units. In small cities Kwid continues to be the number one selling car from Renault. Ghosn said Kwid has put Renault on strong foot in India. The company initially struggled because it was the new plant and a new car, so when you have so much innovation accommodated, you struggle with profitability, he added. Kwid now caters to the needs of three different customer types, with a scope of options to suit specific lifestyles. The 0.8 litre for the customer who seeks a superior package with the best fuel efficiency. The 1.0 litre MT for the customer who seeks a superior package along with more performance. The 1.0 Litre AMT for the customer who seeks a superior package with more Performance and greater convenience. Design element also helped the car as customers were looking for a car which is slightly taller with a tinge of sporty element built into it, which Kwid addressed. Ghosn, who is impressed with India’s frugal engineering, said that Ratan Tata’s dream project Nano has contributed to Renault’s success in India. It may be noted Nissan’s much expected low cost brand Datsun has not met with the success it was expecting. On Datsun, Ghosn said: “We are not as successful with Datsun as we would have liked it to be but when you are in a long term strategy we don’t expect success to come immediately.” Ghosn said that with the A-platform — the second of the so-called common module family, or CMF, jointly developed by Renault and Nissan, a sort of modular manufacturing system for cars– particularly with the Kwid and all the products that are going to follow that. This platform will be open to Mitsubishi also.

Careers, technology on display at manufacturing show – Chippewa Herald

Cole Hill knows what he wants to do in a future career. I want to build motors V-8s probably, said the Colfax High School junior who spends time racing at the Red Cedar and Jim Falls tracks.

But just what does one study to prepare to build big engines? Hunter Sullivan of Chippewa Falls, a Chippewa Valley Technical College Machine Tooling Technics student, had some ideas for him at CVTCs annual Manufacturing Show Thursday, March 2.

He told me about their CNC (computerized numerical control) machines and the careers, said Hill, who thinks he will eventually enroll at CVTC, but he is unsure of which program. I havent looked at any other places.

Introducing people like Hill to careers in manufacturing is a big part of CVTCs Manufacturing Show, which drew about 1,600 people to CVTCs Manufacturing Education Center. Wonders of modern manufacturing were displayed and demonstrated in CVTCs Automation Engineering Technology, Industrial Mechanical, Machine Tooling Technics and Welding/Welding Fabrication, as well as Manufacturing, Nano and Industrial Engineering programs.

About 40 manufacturing companies were also represented with display tables highlighting their products and job opportunities.

Sullivan, a 2015 Chippewa Falls Senior High School graduate, connected with Hill as another young man who likes to work with his hands. I just like making things, Sullivan said. I took shop classes in high school with manual lathes and I thought that was pretty cool. But what I learn here is way more than they teach you in high school.

Sullivan is already working in manufacturing, doing some part-time laser cutting work at Riverside Machine. Im not doing CNC work, but hopefully when I finish school they will keep me on as a machinist, he said.

Visitors at the Manufacturing Show were able to take part in hands-on activities like trying their hand at welding, building a tiny flashlight with the help of Manufacturing Engineering Technologist students, or playing with projects like a billiards game made by Automation Engineering Technology students.

This is an opportunity to show off new technology, said CVTC Dean of Manufacturing Jeff Sullivan. The Manufacturing Show brings together alumni and people in the area, and shows off student projects. Our manufacturing partners come in and show the things theyre doing.

Several area high schools sent busloads of students who also toured some area manufacturing companies prior to the show. Other high school students came on their own, or with their parents.

Tim Frank of Menomonie, a CVTC graduate himself, came with his wife and son, Nathan. Hes interested in coming here next year, Frank said. Hes working at a machine shop in Menomonie after school now. He saw this show was available and asked to come.

I really havent decided what program to take, Nathan said. But it will probably be something in the machining area. Its making stuff. Its hands-on.

Dawn Schrankler and her husband brought their daughter, Kelsey, from Neillsville for the show. Were trying to get her interested in more of a selection, said Schrankler. She wants to be a veterinarian assistant, but were trying to broaden her horizons and open her eyes to other areas.

But not all of the people attending the show to explore careers were high school students or even recent high school graduates. People looking for a change of careers found plenty of older CVTC students who followed a similar path.

This program is fantastic, said Casey Schellhorn, an Automation Engineering Technology student who graduated from River Falls High School back in 2010. I wanted more opportunity than I had working in food service. I was looking for something interesting and found this on the CVTC website.

Schellhorn was stationed where he could explain to visitors how to play a miniature billiards game and also the pneumatics, electronics and sensors that made the game work. In all the program areas, other students were present to explain what they do, what they are learning, and the exciting opportunities available to them in manufacturing careers.

Associate chemical engineering professor recognized by The Welch Foundation – UT The Daily Texan

The Welch Foundation, one of the largest funding resources for chemical research, recognized associate professor Delia Milliron for her contribution to controlling sunlight from entering buildings, according to the foundations website.

Last Wednesday, The Welch Foundation announced Milliron as one of the two recipients of the 2017 Norman Hackerman Award in Chemical Research. The award was established to honor Norman Hackerman, the foundations scientific advisory board member, with the purpose of supporting Texas scientists who are dedicated to increasing the fundamental understanding of chemistry.

Milliron said it is a great honor to be recognized by The Welch Foundation, and she is very proud to receive this award.

(The Welch Foundation is) a very important supporter of chemistry across the state of Texas, and they found some of the research in my lab and in many others across campus and around the state, Milliron said over the phone. Its a really important driver of innovation in Texas to have the Welch foundation supporting us with grants and with awards like this one.

Milliron is also an associate editor of Nano Letters, a journal of the American Chemical Society, which includes publications related to nanomaterial chemistry.

Thomas Truskett, chair of the McKetta Department of Chemical Engineering, said Milliron is a rising star in the chemical sciences, and she is well-deserved of the award.

The Hackerman Award is a fiercely competitive prize, Truskett said in an email. The fact that Dr. Milliron was chosen for it this year, as well as another colleague from our Department last year, points toward the excellence of our young faculty, who represent the future of the Department.

The Welch Foundation is based in Houston and has contributed to the advancement of chemistry by supporting institutions in Texas with research grants and special projects, according to the foundations website.

Chemistry freshman Andrea Torres said its inspiring to see Millirons recogniton, because she represents a strong female leader in the scientific community.

For a long time chemistry and sciences in general were predominantly male, and to have a woman win an award like that its a pretty big deal, Torres said. It shows that we have a program thatpushes innovation.

New Microscopy Tech Offers a Kind of Nano-GPS for Measuring Magnetism of Atoms – IEEE Spectrum

Gif: Nature Nanotechnology

Researchers at IBM Research Alamaden have developed a new approach to measuring the magnetic field of individual atoms that for the first time gives scientists the ability to put the sensor exactly next to the atom they want to measure, providing them with a strong and direct signal of the magnetic field.The energy resolution that the new technologyprovides is more than 1000 times higher than other microscopic techniques, according to its inventors.

The technique involves purposely placing a “sensor” atomnear thetargetatom to measure the latters magnetic field. These sensor atomsalso known as electron spin resonance (ESR) sensorswere first developed by IBM back in 2015 and are used inside of scanning tunneling microscopes (STMs). STMswhich detect the tunneling of electrons between the an ultra-sharp probe as its scanned across a surfaceallow atom-by-atom engineering, so that the positions of both the sensor and the target atoms can be imaged to locate them with atomic precision.

This latest advance in STMs with ESR technology described in the journal Nature Nanotechnology marks a distinct change from how the magnetic fields of atoms have previously been measured.

We have shown in the paper how to perform a kind of nano-GPSimaging, to detect where other magnetic atoms were located purely by the spin resonance signal on several fixed sensor atoms, says Christopher Lutz, a staff scientist at IBM Research Almaden. We intend to use this to image where magnetic centers are in molecules and nanostructures on the surface.

Prior to this latest work, one of the most notable techniques for measuring the magnetic fields of atoms involved exploiting defects in diamondcalled nitrogen-vacancy (NV) centerswhich can measure the magnetic fields from individual atoms within the diamond crystal.

But with that approach the NV center location is random; it cannot be moved around within the diamond crystal, according to Lutz. He further notes that while the diamond containing the NV can be moved near another object to image it magnetically it is presently limited to about 10 nanometers distance, because it is hard to get an NV center with usable properties close enough to the diamond surface.

Lutz also points out that there had been earlier work at IBM in measuring the magnetic field of atoms in which they demonstrated it was possible to detect a weak magnetic force from an individual atom. However, the signals were very challenging to detect, he says.The signal from the new STM technique is much stronger and more robust. We can sense the magnetic field of other atoms directly, which gives clear measure of their magnetic moments and other magnetic properties.

This additional information on the magnetic properties of atoms complements the other kinds of information that regular STMs give, like the location of atoms on a surface and their tunneling spectrathe conductance as a function of the voltage. (The lattergives information on the an atoms electronic structure.) According to Lutz, this means an energy resolution that is 1000 times as sensitive as other microscopic techniques, making it possible to see weak interactions.

This allows weak interaction like magnetic coupling between well-separated atoms to be measured, he says. It can probe structures non-invasively, from several nanometers away, where they are undisturbed by our probe atom.

The operating principle of these ESR sensors depends on what happens when an atom with unpaired electron spins is placed in a magnetic field. It does something called precess, which means its axis rotates around the magnetic field at a precise frequency. This frequency depends on the field strength and the atom’s magnetic moment, which is the strength of the atom’s magnetism.

In our experiment, we apply a magnetic field to the microscope, and then apply a high-frequency voltage to the tunnel junction of the microscope, explains Lutz. When the frequency matches the frequency of the spin precession, it drives the spin away from its thermal equilibrium, in which it is mostly aligned with the magnetic field.

This change in orientation is detected bytransferring a single magnetic sensor atom, in this case iron, to the microscope tip.The frequency is swept through the resonance frequency, and a sharp change in tunnel current appears precisely at the resonant frequency. The resonancefrequency moves in response to nearby magnetic atoms.

The physical principle is the same as for magnetic resonance imagingexcept that we detect electron precession instead of nuclear precession, and we address individual atoms instead of billions of them, by positioning the tip over the atom of interest, adds Lutz.

The technical hurdles in achieving these measurements are pretty high. First, high-frequency cabling is needed to bring gigahertz signals to the STM tip in order to drive the atom’s spin resonantly. Meanwhile,the STM itself must be maintained in an ultra-high vacuum, at liquid helium temperatures, and in an applied magnetic field of just the right magnitude.

We remain the only group able to perform single-atom ESR in an STM, saysLutz. However, we are studying ways to relax the stringent conditions needed to make it work, in order to make this a more general technique and so other groups can make use of it.

Lutz expects that a few other research groups will be able to perform thismeasurement once they installa gigahertz connection in their STM.

We hope to achieve spin resonance on a wider variety of atom types and surface materials, and to relax the extreme conditions needed for this experiment, so that in time more labs can use it, he says.

I really havent decided what program to take, Nathan said. But it will probably be something in the machining area. Its making stuff. Its hands-on.

Dawn Schrankler and her husband brought their daughter, Kelsey, from Neillsville for the show. Were trying to get her interested in more of a selection, said Schrankler. She wants to be a veterinarian assistant, but were trying to broaden her horizons and open her eyes to other areas.

But not all of the people attending the show to explore careers were high school students or even recent high school graduates. People looking for a change of careers found plenty of older CVTC students who followed a similar path.

This program is fantastic, said Casey Schellhorn, an Automation Engineering Technology student who graduated from River Falls High School back in 2010. I wanted more opportunity than I had working in food service. I was looking for something interesting and found this on the CVTC website.

Schellhorn was stationed where he could explain to visitors how to play a miniature billiards game and also the pneumatics, electronics and sensors that made the game work. In all the program areas, other students were present to explain what they do, what they are learning, and the exciting opportunities available to them in manufacturing careers.

25 years later, buckyball a big find on small scale

This Houston Chronicle story ran on Oct. 11, 2010. The headline and words are reprinted below.

As is so often the case with great scientific discoveries, Rick Smalley, Bob Curl and Harry Kroto weren’t looking for buckyballs when they found them in 1985.

Smalley had built a fancy machine at Rice University that used lasers to vaporize bits of metal. Kroto, meanwhile, wanted to better understand the nature of tiny chains of carbon dust between stars, so he asked his friend Curl if he wouldn’t mind sticking a chunk of graphite inside Smalley’s machine.

They did, and unexpectedly discovered a unique form of carbon in which 60 atoms clustered neatly into a tiny, soccer-shaped ball. They christened their finding a buckyball – or fullerene – after Buckminster Fuller, whose geodesic designs the molecules resemble.

The discovery a quarter century ago won the trio a Nobel Prize in 1996 and is, in no small part, responsible for launching the field of nanotechnology.

Prior to the discovery, scientists – most famously Richard Feynman – had mused about manipulating and controlling atoms to perform special tasks.

But it remained mostly talk until the creation of a buckyball, essentially a tiny protective cage in which scientists could put other atoms, crystallized the possibility of creating particles with special properties.

“That got people thinking about how we could design molecules with tailor-made properties,” said Gustavo Scuseria, a Rice chemist who came to the university four years after the discovery in large part because of the excitement it spurred.

“People were talking about nanoscience before, but there was no clear example of what could be a brick builder for nanotechnology. With the buckyball it was evident to everyone that this changed the game.”

Latest developments

The buckyball itself hasn’t delivered on some of the early hype, but its discovery led scientists to find more useful carbon materials, such as long, skinny carbon nanotubes and more recently, graphene, a one-atom-thick sheet of carbon atoms.

The 2004 discovery of graphene by Russian scientists Andre Geim and Konstantin Novoselov, in fact, won the pair the 2010 Nobel Prize in physics last week.

“The principal effect of the fullerene discovery has been the development of intense worldwide interest in the chemistry of elemental carbon with several unusual and interesting new structures discovered,” Curl said. “I am happy that our discovery has led to such a great deal of good science.”

Carbon nanotubes and graphene are being studied for a raft of new technologies, from flexible TV displays to lightweight spacecraft materials to tiny and powerful semiconductors.

Beyond leading to new forms of carbon, the buckyball led scientists to tinker with the atom-by-atom design of materials for electronics and other purposes. The touch screens of many smart phones, for example, are possible because the use of nanomaterial to “paint” indium tin oxide on the front to create a transparent conductor.

Explosion of products

Nanotechnology also has worked its way into more conventional goods such as washing machines and air conditioners as engineers have embedded tiny bits of silver to take advantage of its antimicrobial properties.

The Project on Emerging Nanotechnologies conservatively estimates that the number of nanotechnology-enabled products has risen from 54 in 2005 to more than 1,000 last year.

After winning the Nobel Prize in 1996, Smalley, who died of leukemia at the age of 62 in 2005, became an evangelist for nanotechnology. He urged President Bill Clinton to increase research funding, and with the help of Clinton’s science adviser Neal Lane, the National Nanotechnology Initiative was begun in 2001.

Since then it has provided $14 billion in federal funding for nanotechnology research, with other federal agencies, including the National Institutes of Health and Department of Defense, providing as much or more.

“There was not a lot of push-back,” Lane recalled of Capitol Hill. “It was pretty easy to explain to members of Congress if you can make things on a smaller and smaller scale and build them from the bottom up, you could make some things that might have a major impact on new kinds of medical treatments, new ways of computing and new materials that could revolutionize a lot of areas.”

Boon for Houston

The buckyball’s discovery was also a financial boon for Houston.

It has led to at least $500 million in federal research funding coming to Rice for its many nanotechnology research programs, said Wade Adams, director of Rice’s Smalley Institute for Nanoscale Science and Technology.

It’s also spilled into other institutions in the Texas Medical Center and the University of Houston, where there are intensive programs to study the use of nanomaterials to treat disease, such as tiny gold shells that burn cancer cells and special drug-delivery devices that carry tumor-killing agents directly into cancers.

Nanotechnology’s potential has only begun to be tapped, says Philip Lippel, an advisory board member for NanoBusiness Alliance.

While some technologies are near the market – engineers are counting on nanomaterials to continue the trend of ever-increasingly powerful computer processors and memory chips – others remain in various stages of development.

Medical applications take longer, he said, because they must first be developed in a laboratory and then pass through various phases of safety and effectiveness testing by the U.S. Food and Drug Administration.

Just the beginning

Longer-term there’s also hope nanomaterials may provide leaps to make technologies such as solar energy and water desalinization both efficient and cost-effective.

“I think we are just beginning to see what nanotechnology is capable of,” Lippel said. “A lot of good 20th-century engineering solutions to energy, water, communications are going to have their economics changed by nanomaterials.”

Lippel sees nanotechnology as a great enabling technology, similar to computing and information technology during the latter half of the 20th century.

But Peter Bishop, a University of Houston future studies professor, isn’t ready to go that far, at least not yet.

“I don’t put nanotechnology in the same category as some of the more disruptive technologies in our history like machines, coal, railroads, telephone or electricity,” he said.

Instead he says nanotechnology will be more of an invisible, under-the-hood technology that provides incremental changes and allows people to do things better. He says nanotechnology may be more like the plastics of the 21st century.

“No one called the middle of the last century the plastics era, but it certainly was an important step forward in materials science,” he said.

We’ll just have to wait until the buckyball’s golden anniversary to settle the question.

UPDATE

In recent years, Houston universities and Texas Medical Center institutions have continued to invest resources in nanotechnology, cementing Houston as a national research hub for all things on the nano scale.

In 2013, Rice university took the logical step creating the Department of Material Sciences and Nanoengineering, two fields that Rice researchers have dominated for years.

Two years later, the university was tapped by the National Science Foundation to establish the Nanotechnology Enabled Water Treatment Systems, Houston’s first NSF Energy Research Center and the third in Texas.

That same year, the university announced it would invest $49 million in molecular nanotechnology.

The University of Houston launched its first nanotechology spinoff in 2013; Integricote, based in the university’s Energy Research Park, produces protective coatings for wood and masonry, based on the work of physicist Seamus Curran.

Several other nanotech-based products for the energy industry are undergoing commercial testing, including an enhanced oil recovery fluid developed by physicist Zhifeng Ren, a pioneer in working with carbon nanotubes recruited from Boston College in 2013, and a “smart” cement, developed by engineer Cumaraswamy Vipulanandan, that can alert engineers to potential problems with a well before they become dangerous.

In 2010, Houston Methodist made a major investment in the future of nanotechnology by poaching nanomedicine pioneer Dr. Mauro Ferrari from the University of Texas Health Science Center to run the Houston Methodist Research Institute.

While there, Ferrari has continued to pursue his research including a nano-based technology that has been shown in mouse studies to destroy a lethal-type of breast cancer after it reached the lungs, a stage of the disease once considered untreatable.

Likewise, Ferrari has recruited a crop of highly-regarded scientists to the Institute where they continue to develop new ways to merge nanotechnology and medicine.

One such recruit, Dr. Alessandro Grattoni who now leads the Institute’s Department of Nanomedicine, recently the launched the first of its kind Center of Space Nanomedicine.

Last year, Grattoni and his team had one of their experiments conducted aboard the International Space Station. That experiment involved testing a device that uses “nano channels” to deliver medication in a super precise manner. Another experiment is set to be launched in April.

Nano-sized hydrogen storage system increases efficiency – Space Daily

Lawrence Livermore scientists have collaborated with an interdisciplinary team of researchers including colleagues from Sandia National Laboratories to develop an efficient hydrogen storage system that could be a boon for hydrogen powered vehicles.

Hydrogen is an excellent energy carrier, but the development of lightweight solid-state materials for compact, low-pressure storage is a huge challenge.

Complex metal hydrides are a promising class of hydrogen storage materials, but their viability is usually limited by slow hydrogen uptake and release. Nanoconfinement – infiltrating the metal hydride within a matrix of another material such as carbon – can, in certain instances, help make this process faster by shortening diffusion pathways for hydrogen or by changing the thermodynamic stability of the material.

However, the Livermore-Sandia team, in conjunction with collaborators from Mahidol University in Thailand and the National Institute of Standards and Technology, showed that nanoconfinement can have another, potentially more important consequence. They found that the presence of internal “nano-interfaces” within nanoconfined hydrides can alter which phases appear when the material is cycled.

The researchers examined the high-capacity lithium nitride (Li3N) hydrogen storage system under nanoconfinement. Using a combination of theoretical and experimental techniques, they showed that the pathways for the uptake and release of hydrogen were fundamentally changed by the presence of nano-interfaces, leading to dramatically faster performance and reversibility. The research appears on the cover of the Feb. 23 edition of the journal Advanced Materials Interfaces.

“The key is to get rid of the undesirable intermediate phases, which slow down the material’s performance as they are formed or consumed. If you can do that, then the storage capacity kinetics dramatically improve and the thermodynamic requirements to achieve full recharge become far more reasonable,” said Brandon Wood, an LLNL materials scientist and lead author of the paper.

“In this material, the nano-interfaces do just that, as long as the nanoconfined particles are small enough. It’s really a new paradigm for hydrogen storage, since it means that the reactions can be changed by engineering internal microstructures.”

The Livermore researchers used a thermodynamic modeling method that goes beyond conventional descriptions to consider the contributions from the evolving solid phase boundaries as the material is hydrogenated and dehydrogenated. They showed that accounting for these contributions eliminates intermediates in nanoconfined lithium nitride, which was confirmed spectroscopically.

Beyond demonstrating nanoconfined lithium nitride as a rechargeable, high-performing hydrogen-storage material, the work establishes that proper consideration of solid-solid nanointerfaces and particle microstructure are necessary for understanding hydrogen-induced phase transitions in complex metal hydrides.

“There is a direct analogy between hydrogen storage reactions and solid-state reactions in battery electrode materials,” said Tae Wook Heo, another LLNL co-author on the study.

“People have been thinking about the role of interfaces in batteries for some time, and our work suggests that some of the same strategies being pursued in the battery community could also be applied to hydrogen storage. Tailoring morphology and internal microstructure could be the best way forward for engineering materials that could meet performance targets.”
