Professors Chang, Cohen, Christofides, Lu, Monbouquette, and Sautet

Research on surface chemistry and physics is the foundation for discovery of surface-engineered materials that have applications in the fields of separations, sensing, and semiconductors. Faculty in the Chemical & Biomolecular Engineering Department at UCLA work in the areas of macromolecular and nano-surface engineering to develop more efficient and selective membranes and sorption resins, design new molecular chemical sensors, synthesize biocompatible surfaces, and manipulate heterogeneous surface processes at the atomic scale.

Molecular modeling and experimental investigations are geared towards understanding the structure of silylated and graft-polymerized surfaces (e.g., topology, conformation and distribution) and devising physical and chemical methods (e.g., graft polymerization and self-assembly) to control surface properties. Recent major accomplishments in this area are patented ceramic-polymer composite membranes (Cohen Group). This membrane, with a nano-structured separation layer, has proven effective in protein ultrafiltration and pervaporation separation of organic-organic and organic-aqueous mixtures.

Molecular engineering of innovative, self-assembling systems that mimic biological systems is researched to solve technological problems. For example, an approach that magnetobacteria use has been harnessed to produce the magnetite particles needed for magnetotaxis in the synthesis of semiconductor nanoparticles (Monbouquette Group). Size monodisperse, 100-nm-diameter phospholipid vesicles serve as compartments for synthesis of

Professor Nobe also focuses on investigating physical properties of electrodeposited quantum dots, nanomagnets, nanowires (10 to 400 nm diam. with aspect ratios up to 18,000), nanostructured multilayers, and metal oxide and conducting polymer supercapacitors. The figure shows an example of an electrochemical nano system (ENS) where cobalt nanowires were electrodeposited from anodized alumina templates.

Atomic layer deposition (ALD) to engineer nanometer thin films and nanolaminates with atomic resolution and controllability is also being studied (Chang Group). Highly uniform, conformal, and stoichiometric films can be easily synthesized, for example, nanolaminates can be formed through the use of multiple chemical precursors in alternating reaction sequences. ALD has been used to deposit metals, metal oxides, metal nitrides, semiconductors, transparent conductive oxides, and ferroelectric materials, with potential applications in microelectronics, membrane, sensor, bioceramic, and catalysis.

Professor Hicks group has developed a method of simulating reactions on compound semiconductor surfaces using molecular cluster calculations with density functional theory. Using this method, a cluster model for a gallium arsenide surface has been developed, which identified all the reaction sites on the surface as being an arsenic dimer and two second-layer gallium atoms. Each arsenic dangling bond is filled with a pair of electrons, while each gallium dangling bond is empty, in excellent agreement with experimental observations. The most exciting result from this work is the prediction of the vibrational frequencies of the optimized clusters and their excellent comparison with infrared data. This unique capability allows a definitive assignment of the observed vibrational bands to specific adsorption sites. This method is currently being applied to the study of surface reaction mechanisms for organometallic precursors.

Nanoengineering – Wikipedia

Nanoengineering is the practice of engineering on the nanoscale. It derives its name from the nanometre, a unit of measurement equalling one billionth of a meter.

Nanoengineering is largely a synonym for nanotechnology, but emphasizes the engineering rather than the pure science aspects of the field.

The first nanoengineering program was started at the University of Toronto within the Engineering Science program as one of the options of study in the final years. In 2003, the Lund Institute of Technology started a program in Nanoengineering. In 2004, the College of Nanoscale Science and Engineering at SUNY Polytechnic Institute was established on the campus of the University at Albany. In 2005, the University of Waterloo established a unique program which offers a full degree in Nanotechnology Engineering. [1] Louisiana Tech University started the first program in the U.S. in 2005. In 2006 the University of Duisburg-Essen started a Bachelor and a Master program NanoEngineering. [2] Unlike early NanoEngineering programs, the first Nanoengineering Department in the world, offering both undergraduate and graduate degrees, was established by the University of California, San Diego in 2007.In 2009, the University of Toronto began offering all Options of study in Engineering Science as degrees, bringing the second nanoengineering degree to Canada. Rice University established in 2016 a Department of Materials Science and NanoEngineering (MSNE).DTU Nanotech – the Department of Micro- and Nanotechnology – is a department at the Technical University of Denmark established in 1990.

In 2013, Wayne State University began offering a Nanoengineering Undergraduate Certificate Program, which is funded by a Nanoengineering Undergraduate Education (NUE) grant from the National Science Foundation. The primary goal is to offer specialized undergraduate training in nanotechnology. Other goals are: 1) to teach emerging technologies at the undergraduate level, 2) to train a new adaptive workforce, and 3) to retrain working engineers and professionals.[3]

Undergraduate Degree Programs | NanoEngineering

The Department of NanoEngineering offers undergraduate programs leading to theB.S. degreesinNanoengineeringandChemical Engineering. The Chemical Engineering and NanoEngineering undergraduate programs areaccredited by the Engineering Accreditation Commission of ABET. The undergraduate degree programs focus on integrating the various sciences and engineering disciplines necessary for successful careers in the evolving nanotechnology industry.These two degree programshave very different requirements and are described in separate sections.

B.S. NanoEngineering

TheNanoEngineering Undergraduate Program became effective Fall 2010.Thismajor focuses on nanoscale science, engineering, and technology that have the potential to make valuable advances in different areas that include, to name a few, new materials, biology and medicine, energy conversion, sensors, and environmental remediation. The program includes affiliated faculty from the Department of NanoEngineering, Department of Mechanical and Aerospace Engineering, Department of Chemistry and Biochemistry, and the Department of Bioengineering. The NanoEngineering undergraduate program is tailored to provide breadth and flexibility by taking advantage of the strength of basic sciences and other engineering disciplines at UC San Diego. The intention is to graduate nanoengineers who are multidisciplinary and can work in a broad spectrum of industries.

B.S. Chemical Engineering

The Chemical Engineering undergraduate program is housed within the NanoEngineering Department. The program is made up of faculty from the Department of Mechanical and Aerospace Engineering, Department of Chemistry and Biochemistry, the Department of Bioengineering and the Department of NanoEngineering. The curricula at both the undergraduate and graduate levels are designed to support and foster chemical engineering as a profession that interfaces engineering and all aspects of basic sciences (physics, chemistry, and biology). As of Fall 2008, the Department of NanoEngineering has taken over the administration of the B.S. degree in Chemical Engineering.

Academic Advising

Upon admission to the major, students should consult the catalog or NanoEngineering website for their program of study, and their undergraduate/graduate advisor if they have questions. Because some course and/or curricular changes may be made every year, it is imperative that students consult with the departments student affairs advisors on an annual basis.

Students can meet with the academic advisors during walk-in hours, schedule an appointment, or send messages through the Virtual Advising Center (VAC).

Program Alterations/Exceptions to Requirements

Variations from or exceptions to any program or course requirements are possible only if the Undergraduate Affairs Committee approves a petition before the courses in question are taken.

Independent Study

Students may take NANO 199 or CENG 199, Independent Study for Undergraduates, under the guidance of a NANO or CENG faculty member. This course is taken as an elective on a P/NP basis. Under very restrictive conditions, however, it may be used to satisfy upper-division Technical Elective or Nanoengineering Elective course requirements for the major. Students interested in this alternative must have completed at least 90 units and earned a UCSD cumulative GPA of 3.0 or better. Eligible students must identify a faculty member with whom they wish to work and propose a two-quarter research or study topic. Please visit the Student Affairs office for more information.

NETS – What are Nanoengineering and Nanotechnology?

is one billionth of a meter, or three to five atoms in width. It would take approximately 40,000 nanometers lined up in a row to equal the width of a human hair. NanoEngineering concerns itself with manipulating processes that occur on the scale of 1-100 nanometers.

The general term, nanotechnology, is sometimes used to refer to common products that have improved properties due to being fortified with nanoscale materials. One example is nano-improved tooth-colored enamel, as used by dentists for fillings. The general use of the term nanotechnology then differs from the more specific sciences that fall under its heading.

NanoEngineering is an interdisciplinary science that builds biochemical structures smaller than bacterium, which function like microscopic factories. This is possible by utilizing basic biochemical processes at the atomic or molecular level. In simple terms, molecules interact through natural processes, and NanoEngineering takes advantage of those processes by direct manipulation.

The NanoEngineering Graduate Program provides a course of study for both the M.S. and Ph.D. degrees, with a focus on underlying scientific, technical and engineering challenges for advancing nanotechnology in the controlled synthesis of nanostructured materials, especially for biomedical, energy, and environmentally-related technologies. Our graduate degree program is uniquely designed to educate students with a highly interdisciplinary curriculum, focusing on core scientific fundamentals, but extending the application of that fundamental understanding to complex problems requiring the ability to integrate across traditional science and engineering boundaries. Specific courses in our core cluster address both the fundamental science and the integration of this science into engineering problem solving. Three main educational paths within the single degree title NanoEngineering are proposed:

The new NE curriculum has the following objectives:

In NanoEngineering, we design and manufacture devices and systems that exploit the unique properties of nanoscale materials to create entirely new functionality and capabilities. Due to the scale of engineering involved, the field of NanoEngineering is inherently interdisciplinary that often utilizes biochemical processes to create nanoscale materials designed to interact with synthetic inorganic materials. The curriculum is built to address the educational needs of this new engineering field.

About the NANO-ENGINEERING FLAGSHIP

Turning the NaI concept into reality necessitates an extraordinary and long-term effort. This requires the integration of nanoelectronics, nanophotonics, nanophononics, nanospintronics, topological effects, as well as the physics and chemistry of materials. This also requires operations in an extremely broad range of science and technology, including Microwaves, Millimeter waves, TeraHertz, Infrared and Optics, and will exploit various excitations, such as surface waves, spin waves, phonons, electrons, photons, plasmons, and their hybrids, for sensing, information processing and storage. Integrating

This high level of integration, which goes beyond individual functionalities, components and devices and requires cooperation across a range of disciplines, makes the Nano Engineering Flagship unique in its approach. It will be crucial in tackling the 6 strategic challenges identified as:

People Would Rather a Self-Driving Car Kill a Criminal Than a Dog

Snap Decisions

On first glance, a site that collects people’s opinions about whose life an autonomous car should favor doesn’t tell us anything we didn’t already know. But look closer, and you’ll catch a glimpse of humanity’s dark side.

The Moral Machine is an online survey designed by MIT researchers to gauge how the public would want an autonomous car to behave in a scenario in which someone has to die. It asks questions like: “If an autonomous car has to choose between killing a man or a woman, who should it kill? What if the woman is elderly but the man is young?”

Essentially, it’s a 21st century update on the Trolley Problem, an ethical thought experiment no doubt permanently etched into the mind of anyone who’s seen the second season of “The Good Place.”

Ethical Dilemma

The MIT team launched the Moral Machine in 2016, and more than two million people from 233 countries participated in the survey — quite a significant sample size.

On Wednesday, the researchers published the results of the experiment in the journal Nature, and they really aren’t all that surprising: Respondents value the life of a baby over all others, with a female child, male child, and pregnant woman following closely behind. Yawn.

It’s when you look at the other end of the spectrum — the characters survey respondents were least likely to “save” — that you’ll see something startling: Survey respondents would rather the autonomous car kill a human criminal than a dog.

moral machine

Ugly Reflection

While the team designed the survey to help shape the future of autonomous vehicles, it’s hard not to focus on this troubling valuing of a dog’s life over that of any human, criminal or not. Does this tell us something important about how society views the criminal class? Reveal that we’re all monsters when hidden behind the internet’s cloak of anonymity? Confirm that we really like dogs?

The MIT team doesn’t address any of these questions in their paper, and really, we wouldn’t expect them to — it’s their job to report the survey results, not extrapolate some deeper meaning from them. But whether the Moral Machine informs the future of autonomous vehicles or not, it’s certainly held up a mirror to humanity’s values, and we do not like the reflection we see.

Scientists Say New Material Could Hold up an Actual Space Elevator

Space Elevator

It takes a lot of energy to put stuff in space. That’s why one longtime futurist dream is a “space elevator” — a long cable strung between a geostationary satellite and the Earth that astronauts could use like a dumbwaiter to haul stuff up into orbit.

The problem is that such a system would require an extraordinarily light, strong cable. Now, researchers from Beijing’s Tsinghua University say they’ve developed a carbon nanotube fiber so sturdy and lightweight that it could be used to build an actual space elevator.

Going Up

The researchers published their paper in May, but it’s now garnering the attention of their peers. Some believe the Tsinghua team’s material really could lead to the creation of an elevator that would make it cheaper to move astronauts and materials into space.

“This is a breakthrough,” colleague Wang Changqing, who studies space elevators at Northwestern Polytechnical University, told the South China Morning Post.

Huge If True

There are still countless galling technical problems that need to be overcome before a space elevator would start to look plausible. Wang pointed out that it’d require tens of thousands of kilometers of the new material, for instance, as well as a shield to protect it from space debris.

But the research brings us one step closer to what could be a true game changer: a vastly less expensive way to move people and spacecraft out of Earth’s gravity.

Zero Gravity Causes Worrisome Changes In Astronauts’ Brains

Danger, Will Robinson

As famous Canadian astronaut Chris Hadfield demonstrated with his extraterrestrial sob session, fluids behave strangely in space.

And while microgravity makes for a great viral video, it also has terrifying medical implications that we absolutely need to sort out before we send people into space for the months or years necessary for deep space exploration.

Specifically, research published Thursday In the New England Journal of Medicine demonstrated that our brains undergo lasting changes after we spend enough time in space. According to the study, cerebrospinal fluid — which normally cushions our brain and spinal cord — behaves differently in zero gravity, causing it to pool around and squish our brains.

Mysterious Symptoms

The brains of the Russian cosmonauts who were studied in the experiment mostly bounced back upon returning to Earth.

But even seven months later, some abnormalities remained. According to National Geographic, the researchers suspect that high pressure  inside the cosmonauts’ skulls may have squeezed extra water into brain cells which later drained out en masse.

Now What?

So far, scientists don’t know whether or not this brain shrinkage is related to any sort of cognitive or other neurological symptoms — it might just be a weird quirk of microgravity.

But along with other space hazards like deadly radiation and squished eyeballs, it’s clear that we have a plethora of medical questions to answer before we set out to explore the stars.

We Aren’t Growing Enough Healthy Foods to Feed Everyone on Earth

Check Yourself

The agriculture industry needs to get its priorities straight.

According to a newly published study, the world food system is producing too many unhealthy foods and not enough healthy ones.

“We simply can’t all adopt a healthy diet under the current global agriculture system,” said study co-author Evan Fraser in a press release. “Results show that the global system currently overproduces grains, fats, and sugars, while production of fruits and vegetables and, to a smaller degree, protein is not sufficient to meet the nutritional needs of the current population.”

Serving Downsized

For their study, published Tuesday in the journal PLOS ONE, researchers from the University of Guelph compared global agricultural production with consumption recommendations from Harvard University’s Healthy Eating Plate guide. Their findings were stark: The agriculture industry’s overall output of healthy foods does not match humanity’s needs.

Instead of the recommended eight servings of grains per person, it produces 12. And while nutritionists recommend we each consume 15 servings of fruits and vegetables daily, the industry produces just five. The mismatch continues for oils and fats (three servings instead of one), protein (three servings instead of five), and sugar (four servings when we don’t need any).

Overly Full Plate

The researchers don’t just point out the problem, though — they also calculated what it would take to address the lack of healthy foods while also helping the environment.

“For a growing population, our calculations suggest that the only way to eat a nutritionally balanced diet, save land, and reduce greenhouse gas emission is to consume and produce more fruits and vegetables as well as transition to diets higher in plant-based protein,” said Fraser.

A number of companies dedicated to making plant-based proteins mainstream are already gaining traction. But unfortunately, it’s unlikely that the agriculture industry will decide to prioritize growing fruits and veggies over less healthy options as long as people prefer having the latter on their plates.

Report Identifies China as the Source of Ozone-Destroying Emissions

Emissions Enigma

For years, a mystery puzzled environmental scientists. The world had banned the use of many ozone-depleting compounds in 2010. So why were global emission levels still so high?

The picture started to clear up in June. That’s when The New York Times published an investigation into the issue. China, the paper claimed, was to blame for these mystery emissions. Now it turns out the paper was probably right to point a finger.

Accident or Incident

In a paper published recently in the journal Geophysical Research Letters, an international team of researchers confirms that eastern China is the source of at least half of the 40,000 tonnes of carbon tetrachloride emissions currently entering the atmosphere each year.

They figured this out using a combination of ground-based and airborne atmospheric concentration data from near the Korean peninsula. They also relied on two models that simulated how the gases would move through the atmosphere.

Though they were able to narrow down the source to China, the researchers weren’t able to say exactly who’s breaking the ban and whether they even know about the damage they’re doing.

Pinpoint

“Our work shows the location of carbon tetrachloride emissions,” said co-author Matt Rigby in a press release. “However, we don’t yet know the processes or industries that are responsible. This is important because we don’t know if it is being produced intentionally or inadvertently.”

If we can pinpoint the source of these emissions, we can start working on stopping them and healing our ozone. And given that we’ve gone nearly a decade with minimal progress on that front, there’s really no time to waste.
