Unexpected Strength To Nanothin Sheet Of Material

Unexpected Strength To Nanothin Sheet Of Material
Amazingly Strong Sheet of Nanoparticles
Tightly packed molecules lend unexpected strength to nanothin sheet of material.

Scientists at the University of Chicago and Argonne National Laboratory have discovered the surprising strength of a sheet of nanoparticles that measures just 50 atoms in thickness.

Its an amazing little marvel, said Heinrich Jaeger, Professor in Physics at the University of Chicago. This is not a very fragile layer, but rather a robust, resilient membrane.

Even when suspended over a tiny hole and poked with an ultrafine tip, the membrane boasts the equivalent strength of an ultrathin sheet of plexiglass that maintains its structural integrity at relatively high temperatures.

When we first realized that they can be suspended freely in air, it truly surprised all of us, said Xiao-Min Lin, a physicist at Argonnes Center for Nanoscale Materials.

The characteristics of the nanoparticles are described in the July 22 issue of the journal Nature Materials in a paper written by Jaeger and Lin, along with Klara Mueggenburg, a graduate student in physics at the University of Chicago, and Rodney Goldsmith, an undergraduate student at Xavier University in New Orleans who participated as part of the National Science Foundations Research Experience for Undergraduates program. The work was funded by the NSF-supported Materials Science and Engineering Center at the University of Chicago. Additional support came from the U.S. Department of Energy.........

Laser sets records in power and energy efficiency

Laser sets records in power and energy efficiency
The rise in global terrorism in recent years has brought significant attention to the needs for more advanced sensors and defense technologies to protect civilians and soldiers.

Next-generation laser-based defense systems are now being designed for this need, including the use of infrared countermeasures to protect aircraft from heat-seeking missiles and highly sensitive chemical detectors for reliable early detection of trace explosives and other toxins at a safe distance for personnel.

Since practical systems must be easily portable by a soldier, aircraft or unmanned vehicle, they must be lightweight, compact and power efficient. In addition, such systems also would need to be widely deployable and available to all soldiers, airplanes and public facilities, which requires a low production and operating cost. While several types of lasers exist today that can emit at the desired infrared wavelengths, none of these lasers meet the above requirements because they are either too expensive, not mass-producible, too fragile or require power-hungry and inefficient cryogenic refrigeration.

A new type of semiconductor-based laser, called the Quantum Cascade Laser (QCL), may soon change this situation. Like their computer chip cousins, semiconductors lasers are inherently compact and suitable for mass production, which has led to their widespread and low-cost use in everyday products, including CD and DVD players.........

Creates Transparent Transistors

Creates Transparent Transistors
The Viterbi School's Chongwu Zhou and a team of scientists have created the first prototype of a new design for semiconductors, devices in which transparent electronics are built on top of a flexible transparent base. These devices have the potential of serving as new kinds of displays, including "e-paper" and heads-up displays in automobile windshields or even eyeglasses.

The transistor nanowires also provide a way to embed reliable displays and computing power in thin "smart cards," as per Zhou, an associate professor in the Ming Hsieh Department of Electrical Engineering and in the USC College Department of Chemistry. Zhou was recently named the first holder of the Viterbi School's Jack Munushian Early Career Chair.

His research was published in the recent issue of Nature Nanotechnology.

The fabrication of the prototype nanowire transistors was done in Zhou's laboratory, working from designs co-created by David Janes of the Purdue University School of Electrical Engineering and Computer Engineering, who works in Purdue's Birck Nanotechnology Center; and by Tobin J. Marks, holder of the Vladimir N. Ipatieff chair of chemistry at Northwestern University, who has a joint appointment in Northwestern's Department of Materials Science and Engineering. (See Purdue's press announcement.).........

Safety of Nanotechnology: Risk Vs Benefit

Safety of Nanotechnology: Risk Vs Benefit
There is no doubt that nanotechnology has the potential to make the world a better place, said Project on Emerging Nanotechnologies Chief Scientist Andrew Maynard. But if consumers and other stakeholders are not convinced that the benefits outweigh the risks, a number of applications will not see the light of day. Likewise, if the benefits are unclear and the risks uncertain, the products of nanotechnology will be a hard sell.

Dr. Maynards remark is in his presentation today before a public meeting of the Presidents Council of Advisors on Science and Technology (PCAST). He spoke as part of a panel devoted to addressing and managing the potential health, environmental and safety risks of nanotechnology.

Nanotechnology is turning our world upside down.It also is shaking up our understanding of what makes something harmful and how we deal with that, as per Maynard. He described the current U.S. policy toward managing the possible health and safety risks of nanotechnologies as approaching 21st century technologies with a 20th century mindset.

Maynard called on the federal government to develop a goal-driven risk research strategy to provide decision-makersincluding regulators, industry and consumerswith the scientific information they need to help develop and use nanotechnologies as safely as possible. He suggested an international approach to this challenge based on a set of strategic research questions developed by thirteen top researchers last year which were reported in the journal Nature.........

A breathtaking way to interact with large sets of images

Blaise Aguera y Arcas demonstrates some new technology for registering and interacting with images. Make sure you wait for the end: a three dimensional reconstruction of Notre Dame Cathedral constructed by a computer using people’s digital camera photos downlFlickr.

I would love to see this technology adopted for scientific publication. His sample page from the Guardian was a great example of how it would work. Figures could be much richer and “supplementary” information (which is often important for a paper’s narrative but is left out because of space limitations) could be included where it makes the most sense.

Of course, this would mean different formatting for print and online versions, but jouPLoS ONE might have the flexibility to implement it.

Researchers Help Find New Sub-atomic Particle

Researchers Help Find New Sub-atomic Particle
The Fermilab accelerator complex in Illinois accelerates sub-atomic particles close to the speed of light. Converting energy into mass, the Tevatron collider produces millions of proton-antiproton collisions per second, maximizing the chance for discovery of new particles.
The discovery was made by physicists of the DZero experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory in Batavia, Ill.

Discovery and measurement of the particle's mass will provide new understanding about the basic building blocks of matter.

Local participants in the experiment were physics faculty members Z.D. Greenwood, Lee Sawyer and Markus Wobisch; former post-doctoral researcher Julie Kalk; and current post-doctoral scientists Mike Arov and Joe Steele.

"We've never seen anything like this before," said Sawyer, who is academic director of Tech's physics and chemistry programs. "What is really neat about this is that we have models that predict these things' existence. Discovery is verification of the Standard Model of particle physics".

The Tech team built electronics for part of the DZero detector, which records the path, energy and charge of the particles released during the sub-atomic collisions that are necessary for the project.

"That was a big job," said Greenwood, an associate professor of physics. "It was designed and put together right here at Tech".

In describing Tech's contribution to this frontier of physics, Greenwood said, "Because we are dealing with fundamental particles and trying to understand and contribute to material that describes how the whole universe works, we're necessarily operating at the cutting edge".........

Viable Design for Spin-Based Electronics

Viable Design for Spin-Based Electronics
Physicists at the University of California, San Diego have proposed a design for a semiconductor computer circuit based on the spin of electrons. They say the device would be more scalable and have greater computational capacity than conventional silicon circuits.

The "spintronic"-or spin-based electronic-device, described this week in the journal Nature, would extend the scope of conventional electronics by encoding information with the magnetic-or spin-state of electrons, in addition to the charge of the electrons. The scientists used a novel geometry to overcome the weakness of the magnetic signal, the current limitation to developing spintronics in silicon semiconductors.

"The breakthrough of our research is the device geometry, the way it is activated, and the way it could be integrated in electronic circuits," said Lu J. Sham, a professor of physics at UCSD and the senior author on the paper. "All of these features are novel and our results show for the first time a spin-based semiconductor circuit".

One advantage of spintronics is that it shrinks the size of the circuit that is needed to perform a given logic operation. The scientists say that their proposed device has other important advantages compared with conventional electronics.........
