New imaging technique homes in on electrocatalysis of nanoparticles
Nongjian (NJ) Tao -- a researcher at Arizona State University's Biodesign Institute -- has found a clever way to measure catalytical reactions of single nanoparticles and multiple particles printed in arrays, which will help characterize and improve existing nanoparticle catalysts, and advance the search for new ones.

Controlling superconductors with light
Proffesor Yoram Dagan of Tel Aviv University says that by shining a light on a thin layer of molecules coating a material, he is able to control the critical temperature at which the material can act as a superconductor. His method might be used to develop more powerful computing devices able to save data and run continuously without generating heat and wasting energy.

The laser beam as a '3-D painter'
With laser beams, molecules can be fixed at exactly the right position in a three dimensional material. The new method developed at the Vienna University of Technology can be used to grow biological tissue or to create micro sensors.

Researchers develop method to grow artificial tissues with embedded nanoscale sensors
A multi-institutional research team has developed a method for embedding networks of biocompatible nanoscale wires within engineered tissues. These networks -- which mark the first time that electronics and tissue have been truly merged in 3-D -- allow direct tissue sensing and potentially stimulation, a potential boon for development of engineered tissues that incorporate capabilities for monitoring and stimulation, and of devices for screening new drugs.

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.

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.
