Nanotechnology, or nanotech, is the study and design of machines on the molecular and atomic level. To be considered nanotechnology, these structures must be anywhere from 1 to 100 nanometers in size. A nanometer is equivalent to one-billionth of a regular meter, which means that these structures are extremely small.

Researcher K. Eric Drexler was the first person to popularize this technology in the early 1980s. Drexler was interested in building fully functioning robots, computers, and motors that were smaller than a cell. He spent much of the 80s defending his ideas against critics that thought this technology would never be possible.

Today, the word nanotechnology means something a bit different. Instead of building microscopic motors and computers, researchers are interested in building superior machines atom by atom. Nanotech means that each atom of a machine is a functioning structure on its own, but when combined with other structures, these atoms work together to fulfill a larger purpose.

The U.S. National Nanotechnology Initiative has large plans for nanotech. Mihail Roco, who is involved in this organization, explains the groups future plans by dividing their goals into four generations.

The first generation of nanotech is defined by passive structures that are created to carry out one specific task. Researchers are currently in this generation of the technology.The second generation will be defined by structures that can multitask. Researchers are currently entering this generation and hoping to further their abilities in the near future. The third generation will introduce systems composed of thousands of nanostructurers. The last generation will be defined by nanosystems designed on the molecular level. These systems will work like living human or animal cells.

As nanotech continues to develop, consumers will see it being used for several different purposes. This technology may be used in energy production, medicine, and electronics, as well as other commercial uses. Many believe that this technology will also be used militarily. Nanotechnology will make it possible to build more advanced weapons and surveillance devices. While these uses are not yet possible, many researchers believe that it is only a matter of time.

Adept Armor Announces the Launch of Two New Products: Adept Armor (TM) Fabric Guard and Glass Guard

Posted on by

Los Angeles, CA (PRWEB) January 31, 2014

Adept Armor, a company that produces safe and effective solutions that help make products waterproof, has just announced the launch of two new products: Adept Armor (TM) Fabric Guard and Adept Armor (TM) Glass Guard.

From the day Adept Armor opened for business, they have strived to engineer some of the most amazing and innovative products that can help protect a variety of items. Over time, the company has earned a well-deserved reputation for creating solutions that do just that.

For example, for people who love to buy shoes, bags, hats, dresses, shirts and other clothes, Adept Armor Fabric Guard is an incredible product that is designed to keep fabrics stain-free and waterproof. Although a competitor of Adept Armor created a solution that can help give fabrics an anti-stick quality, it is for industrial use only and tends to cover material with an unattractive milky white coating. Thanks to the products SiO2 nanotechnology, the surface of fabrics that are treated with Fabric Guard will become anti-stick as well as hydrophobic, which means that it will repel both stains and water.

The Fabric Guard has TiO2 molecules for self-cleaning capabilities, preventing mildew and bacteria from growing, an article on the companys website noted, adding that it will also safeguard textile fabrics, keeping them intact against nearly every form of moisture damage.

The TiO2 nano-molecules also prevent UV damage to fabrics, which in turn, keeps the color vibrant as the day you bought it.

The new Adept Armor (TM) Glass Guard also features the same nanotechnology that is found in the Fabric Guard; once it is applied to glass, nothing will stick to the surface. From windshields that get fogged up easily to windows or glass display cases that are covered with fingerprints, Glass Guard will help to keep them oil, dirt and residue-free.

Another product that has been getting a lot of attention lately is the Adept Armor (TM) Circuit Guard; the 4-ounce spray bottle uses the same nanotechnology to help repel water and oil from electronic devices like phones, tablets and iPods.

Anybody who would like to learn more about Adept Armor and its newest products is welcome to visit the companys user-friendly website at any time; there, they can read about Fabric Guard, Glass Guard and more, and how these revolutionary products will help fabric and glass last longer while keeping them looking like new.

How nanotechnology is urine-proofing your smartphone

Posted on by

Mobile & tablets by Ben Sullivan| 30 January 2014 Nanotech firm says that all mobile devices can be 100% waterproof in 5 years. CBR finds out how P2i is testing its 'invisible barrier' against all liquids.

Revolving shower machines, a giant salt bath, and a metre-deep tube that's going to need to hold many bladders' worth of urine. These are just some of the ways Didcot-based tech company P2i is showing how its nano-coating technology is providing absolute safety for electrical devices from the dangers of liquid.

Water damage is one of the main causes for smartphone dysfunctionally, and in turn causes headaches for network operators worldwide as damaged phones increase the risk of customers leaving the lengthy contracts they are now increasingly locked in to.

P2i says it has the answer, and yesterday I was given the opportunity to tour its UK base to talk, and see first hand, the exciting future of nano-coating.

Dr Stephen Coulson started off by submerging his own phone in water, and then setting the timer. The pack of tissues in the photo has also been treated with nano-coating. Not very useful for blowing your nose...

P2i, this week celebrating its 10th birthday, was originally manifested within the Ministry of Defence, which was looking for clothing protection from nerve gases. Since then, under the helm of founder Dr Stephen Coulson, P2i has been developing a process called nano-coating which effectively makes a tiny, ultra-thin shield between a surface and liquid - making the surface hydrophobic.

As you can imagine, network operators are very interested in working alongside phone manufacturers with this technology. A phone that is, to use P2i's trademark phrase 'Dunkable', will not suffer any returns or warranty payouts for water damage, ultimately increasing revenue for operators.

The first 'Dunkable' devices will launch later this year, and the technology differs itself from regular splash-proof coatings. The barrier, which is 1000 times thinner than a human hair, enables manufacturers to reach an IPX7 water protection rating, which is classed as 'submerged for 30 minutes at 1 metre deep'. It was also noted that one customer has asked P2i to test the IPX7 standard with urine, as dropping your phone down the toilet is apparently a lot more common than you first think. CEO Carl Francis admitted: "We're not exactly sure where we're going to get that much urine."

Zettl awarded Foresight Feynman Prize in experimental nanoscience

Posted on by

Richard P. Feynman (1918-1988)

Palo Alto, CA January 23, 2014 Foresight is pleased to announce the winners of the 2013 Foresight Institute Feynman Prizes for Nanotechnology Theory and Experiment.

The winner of the 2013 Feynman Prize for Experiment is Alexander K. Zettl, Professor, Condensed Matter Physics And Materials Science, U.C. Berkeley, and Senior Scientist, Materials Sciences Division, Lawrence Berkeley National Laboratory. The award recognizes Prof. Zettl's exceptional work in the fabrication of nanoscale electromechanical systems (NEMS), spanning multiple decades and including carbon nanotube-based bearings, actuators, and sensors brought to fruition with cutting-edge nanoscale engineering. Making remarkable strides towards nanoscale integrated systems, Prof Zettl produced a reversible mass transport memory device which integrated a nanoparticle and a nanotube into a more complex functional device with external controllability, and most recently a loudspeaker incorporating a graphene diaphragm, demonstrating that high-performance, nanoscale materials can be engineered into usable products even before those materials are fully characterized. Additional accomplishments of his solid state physics research group include chracterizing electronic, magnetic and mechanical properties of diverse nanoscale materials.

The winner of the 2013 Feynman Prize for Theory is David N. Beratan, R.J. Reynolds Professor of Chemistry, Biochemistry, and Physics, Duke University. The award recognizes Prof. Beratan's development of theoretical approaches to understand the function of complex molecular and macromolecular assemblies and machines. The accomplishments of his research group range from formulating the first molecular-level descriptions of how charge flows through proteins and nucleic acids to designing molecular-scale memory devices. His research group established the electron tunneling pathway model for biological electron transfer to understand the molecular machines of bioenergetics, the "inverse design" approach to discover molecular structures with optimal properties, and the first simulations of how chiral information is transferred at the nanoscale through electronic and conformational imprinting..

The awards will be presented at the 2014 Foresight Technical Conference: Integration, to be held February 7-9, 2014 at the Crowne Plaza Cabana Hotel, Palo Alto, CA USA, where the winners will give lectures on their groundbreaking work to leading scientists in the field of nanotechnology.

In awarding the prizes, Ralph C. Merkle, Chairman of the Prize Committee, noted that "The work of these Feynman Prize winners has brought us one step closer to answering Feynman's 1959 question, 'What would happen if we could arrange atoms one by one the way we want them?' The ability to simulate and manipulate atoms advanced by the work of these Prize winners will enable us to design and build engineered molecular machinery with atomic precision. It will take us another step on the way to the development of revolutionary nanotechnologies that will transform our lives for the better."

The annual Feynman Prizes recognize significant advancements on the road to the award of the $250,000 Feynman Grand Prize, an incentive prize that will be awarded to the first researchers to make a nanometer-scale robotic arm and a nanometer-scale computing device, two critical components of an atomic scalemolecular manufacturing system.

The Foresight Feynman Prizes were established by the Foresight Institute in 1993 and named in honor of Nobel Prize winner Richard Feynman whose influential essay, "There's Plenty of Room at the Bottom" inspired the first work on nanoscale science. The Institute awards Feynman prizes each year to recognize researchersone for theoretical work and one for empirical researchwhose recent work has most advanced the field toward the achievement of Feynman's vision for nanotechnology: molecular manufacturing, the construction of atomically-precise products through the use of molecular machine systems.

Mexican University Designs Catalysts With Nanotechnology To Reduce Vehicular Pollution

Posted on by

Currently, they have developed two types of nanocatalysts according to the requirements of Pemex in its process of sulfur removal, from the area of refinement, with which reducing gasoline and diesel to having only 10 parts per million of sulfur has been achieved, as according to international regulation.

This is pointed out by Sergio Fuentes Moyado, head of project and director of CNyN at UNA, located in the northwest state of Baja California. He adds that after three years of research at an experimental level at the Center and pilot tests at the National Institute of Oil, the nanotechnological catalyst counts with a national patent and is ready for tests at a refinery.

CNyN's technology uses molybdenum disulfide and is part of the fifth generation of catalytic converters, although is the first to be conceived since its origin from nanotechnology.

"We look to obtain much more efficient, resistant and cheap catalysts than what we currently can find in the market. That is why, since it design and planning are conceived under the nano concept, which improves some properties of this kind of technologies", Fuentes Moyado highlights.

He explains the process of sulfur removal. "The catalyst eliminates sulfur from the gasoline and diesel molecules, as these are deposited over small arrangements of four to five nanometers and that is where the reaction in presence of hydrogen takes place. So, at the end of the process clean molecules are obtain, that can be used for fuels".

Is important to highlight that the synthesis of the catalyst happened in the Hydrocarbon Processing Laboratory, which was created for this project in the facilities of the CNyN in Baja California.

"Currently we are testing the compound to know if it can be scalated to an industrial level to produce tons instead of kilograms and install the process at a refinery. We have presented a preview of the progress to Pemex and they are very interested in carrying out the test at a refinery. If so, the nanocatalyst would be manufactured in USA, because we don't have a company that can produce them in our country.

"A big infrastructure is required. The design we have made came from the most basic, which is understanding how the molecules bond to the catalyst and how we can force the active sites of the molecules to have more contact with the fluid, being either gasoline or diesel. There is a design involved with the application of knowledge", said the director of CNyN.

The project was funded by the Energy Secretariat (Sener) and the National Counsil of Science and Technology (CONACyT) with more than 66 million of Mexican pesos.

For the creation of the nanocatalyst the Physics and Material Research Institute, the Center of Applied Sciences and Technological Development at UNAM also contributed.

When nanotechnology meets quantum physics in one dimension: New experiment supports long-predicted ‘Luttinger liquid …

Posted on by

Jan. 23, 2014 How would electrons behave if confined to a wire so slender they could pass through it only in single-file?

The question has intrigued scientists for more than half a century. In 1950, Japanese Nobel Prize winner Sin-Itiro Tomonaga, followed by American physicist Joaquin Mazdak Luttinger in 1963, came up with a mathematical model showing that the effects of one particle on all others in a one-dimensional line would be much greater than in two- or three-dimensional spaces. Among quantum physicists, this model came to be known as the "Luttinger liquid" state.

Until very recently, however, there had been only a few successful attempts to test the model in devices similar to those in computers, because of the engineering complexity involved. Now, scientists from McGill University and Sandia National Laboratories have succeeded in conducting a new experiment that supports the existence of the long-sought-after Luttinger liquid state. Their findings, published in the Jan. 23 issue of Science Express, validate important predictions of the Luttinger liquid model.

The experiment was led by McGill PhD student Dominique Laroche under the supervision of Professor Guillaume Gervais of McGill's Department of Physics and Dr. Michael Lilly of Sandia National Laboratories in Albuquerque, N.M. The new study follows on the team's discovery in 2011 of a way to engineer one of the world's smallest electronic circuits, formed by two wires separated by only about 15 nanometers, or roughly 150 atoms.

What does one-dimensional quantum physics involve? Gervais explains it this way: "Imagine that you are driving on a highway and the traffic is not too dense. If a car stops in front of you, you can get around it by passing to the left or right. That's two-dimensional physics. But if you enter a tunnel with a single lane and a car stops, all the other cars behind it must slam on the brakes. That's the essence of the Luttinger liquid effect. The way electrons behave in the Luttinger state is entirely different because they all become coupled to one another."

To scientists, "what is so fascinating and elegant about quantum physics in one dimension is that the solutions are mathematically exact," Gervais adds. "In most other cases, the solutions are only approximate."

Making a device with the correct parameters to conduct the experiment was no simple task, however, despite the team's 2011 discovery of a way to do so. It took years of trial, and more than 250 faulty devices -- each of which required 29 processing steps -- before Laroche's painstaking efforts succeeded in producing functional devices yielding reliable data. "So many things could go wrong during the fabrication process that troubleshooting the failed devices felt like educated guesswork at times," explains Laroche. "Adding in the inherent failure rate compounded at each processing step made the fabrication of these devices extremely challenging."

In particular, the experiment measures the effect that a very small electrical current in one of the wires has on a nearby wire. This can be viewed as the "friction" between the two circuits, and the experiment shows that this friction increases as the circuits are cooled to extremely low temperatures. This effect is a strong prediction of Luttinger liquid theory.

The experiments were conducted both at McGill University and at the Center for Integrated Nanotechnologies, a U.S. Department of Energy, Office of Basic Energy Sciences user facility operated by Sandia National Laboratories.

"It took a very long time to make these devices," said Lilly. "It's not impossible to do in other labs, but Sandia has crystal-growing capabilities, a microfabrication facility, and support for fundamental research from DOE's office of Basic Energy Sciences (BES), and we're very interested in understanding the fundamental ideas that drive the behavior of very small systems."
