Microwave ovens may help produce lower cost solar energy technology
The same type of microwave oven technology that most people use to heat up leftover food has found an important application in the solar energy industry, providing a new way to make thin-film photovoltaic products with less energy, expense and environmental concerns.

Flat lens offers a perfect image
Applied physicists at the Harvard School of Engineering and Applied Sciences have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. It operates at telecom wavelengths -- i.e., those used for fiber-optics -- and is scalable to a wider range.

Novel technique to synthesize nanocrystals that harvest solar energy
A new video protocol in Journal of Visualized Experiments focuses on the liquid phase synthesis of two nanocrystals that produce hydrogen gas or an electric charge when exposed to light. "The main advantage of this technique is that it allows for direct, all inorganic coupling of the light absorber and the catalyst," says the leading author Dr. Mikhail Zamkov of Bowling Green State University.

IBC 2012: New standard HEVC encodes films more efficiently
Television resolution is constantly improving and this must go hand-in-hand with transmitting the data more efficiently. Reputable manufacturers of televisions, computers and mobile telephones, working jointly with Fraunhofer researchers, are developing a new standard for data transmission: "High Efficiency Video Coding", or HEVC for short. This video codec will be unveiled in Amsterdam at the IBC trade show, from Sept. 7 - 11, 2012.

Super-strong, high-tech material found to be toxic to aquatic animals
Carbon nanotubes (CNTs) have potential uses in everything from medicine to electronics to construction. However, CNTs are not without risks. A joint study by the University of Missouri and United States Geological Survey found that they can be toxic to aquatic animals. The researchers urge that care be taken to prevent the release of CNTs into the environment as the materials enter mass production.

Scientists quantify nanofiber health risk to workers
Health risks posed to people who work with tiny fibers used in manufacturing industries could be reduced, thanks to new research. Research into the health risks posed by nanofibers used to strengthen objects from tennis rackets to airplane wings has pinpointed the lengths at which these fibers are harmful to the lungs.

Future memory
A new class of organic materials developed at Northwestern University boasts an attractive but elusive property: Ferroelectricity. The crystalline materials also have a great memory, which could be very useful in computer and cellphone memory applications, including cloud computing. The very long crystals with desirable properties are made using just two small organic molecules that are extremely attracted to each other. The starting compounds are simple and inexpensive, making the lightweight materials scalable for technology applications.

UCSB scientists examine effects of manufactured nanoparticles on soybean crops
Sunscreens, lotions, and cosmetics contain tiny metal nanoparticles that wash down the drain at the end of the day, or are discharged after manufacturing. Those nanoparticles eventually end up in agricultural soil, which is a cause for concern, according to a group of environmental scientists that recently carried out the first major study of soybeans grown in soil contaminated by two manufactured nanomaterials.

Scientists shed light on glowing materials
Researchers at King's College London, in collaboration with European research institutes ICFO and AMOLF, have succeeded in mapping how light behaves in complex photonic materials inspired by nature, like iridescent butterfly wings. Scientists have broken the limit of light resolution at the nanoscale and delivered a fundamental insight into how light and matter interact, which could lead to the development of enhanced bio-sensors for healthcare and more efficient solar cells and displays.

UCSB researchers demonstrate that 15=3x5 about half of the time
Computing prime factors may sound like an elementary math problem, but try it with a large number, say one that contains more than 600 digits, and the task becomes enormously challenging and impossibly time-consuming. Now, a group of researchers at UC Santa Barbara has designed and fabricated a quantum processor capable of factoring a composite number -- in this case the number 15 -- into its constituent prime factors, 3 and 5.

3-D movies in your living room -- without the glasses
New television screens will make it possible for viewers to enjoy three-dimensional television programming without those bothersome 3-D glasses. Still, the content has been rather lacking -- until now. A new technology will soon be adapting conventional 3-D films to the new displays in real time. Researchers will unveil this technology in Berlin at this year's IFA trade show from Aug. 31-Sept. 5.

Nature: Electronic read-out of quantum bits
Quantum computers promise to reach computation speeds far beyond that of today's computers. As they would use quantum effects, however, they would also be susceptible to external interferences. Information flow into and out of the system is a critical point. Researchers from KIT with partners from Grenoble and Strasbourg have now read out the quantum state of an atom directly by using electrodes. In the Nature journal, it is reported about the stable interface between classical and quantum world.

New form of carbon observed
A team of scientists led by Carnegie's Lin Wang has observed a new form of very hard carbon clusters, which are unusual in their mix of crystalline and disordered structure. The material is capable of indenting diamond. This finding has potential applications for a range of mechanical, electronic, and electrochemical uses. The work is published in Science on Aug. 17.

Good vibrations
Using a unique optical trapping system that provides ensembles of ultracold atoms, Berkeley Lab scientists have recorded the first direct observations of distinctly quantum optical effects -- amplification and squeezing -- in an optomechanical system. Their findings point the way toward low-power quantum optical devices and enhanced detection of gravitational waves among other possibilities.
