Nanocrystals and nickel catalyst substantially improve light-based hydrogen production
Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is adding to its appeal by increasing the output and lowering the cost of current light-driven hydrogen-production systems.

Stem cells + nanofibers = Promising nerve research
Using polymer nanofibers thinner than human hairs as scaffolds, researchers have coaxed a particular type of brain cell to wrap around nanofibers that mimic the shape and size of nerves found in the body.

New study reveals challenge facing designers of future computer chips
To build the computer chips of the future, designers will need to understand how an electrical charge behaves when confined to metal wires a few atom-widths in diameter. Now, physicists at McGill University, in collaboration with researchers at General Motors R&D, have shown that electrical current may be drastically reduced when wires from two dissimilar metals meet.

New strategy for fingerprint visualization developed at Hebrew University
Identifying fingerprints on paper is a commonly used method in police forensic work, but unfortunately it is not easy to make those fingerprints visible. Now, scientists at the Hebrew University of Jerusalem have developed a new approach for making such fingerprints more readily readable.

Researchers create laser the size of a virus particle
The miniaturization of the laser -- a key, workhorse instrument -- is critical to ultra-fast data processing and ultra-dense information storage. Now a Northwestern University research team has found a way to manufacture single laser devices that are the size of a virus particle and that operate at room temperature. These plasmonic nanolasers could be readily integrated into silicon-based photonic devices, all-optical circuits and nanoscale biosensors.

Electron microscopes with a twist
Viennese Scientists have developed a new way of producing electron beams in electron microscopes. These beams rotate -- they carry angular momentum. Therefore, they can be used not only to display objects but also to probe their magnetic properties. Using a special kind of screen so-called vortex beams with extraordinary intensity can be created.

New book on physics principles by Wayne State professor explains life as we know it
A new book that delves into the unexpected properties of life at the nanoscale was released this week by Basic Books. "Life's Ratchet: How Molecular Machines Extract Order from Chaos," by Peter M. Hoffmann, Ph.D., professor of physics and materials science and associate dean in Wayne State University's College of Liberal Arts and Sciences, uses the principles of physics -- the science of levers and pulleys, atoms and quarks -- to explain life.

Folding funnels key to biomimicry
Berkeley Lab researchers have shown that a concept widely accepted as describing the folding of a single individual protein is also applicable to the self-assembly of multiple proteins. Their findings provide important guidelines for future biomimicry efforts, particularly for device fabrication and nanoscale synthesis.

Taming mavericks: Stanford researchers use synthetic magnetism to control light
Stanford researchers in physics and engineering have demonstrated a device that produces a synthetic magnetism to exert virtual force on photons similar to the effect of magnets on electrons. The advance could yield a new class of nanoscale applications that use light instead of electricity.

Stanford scientists build the first all-carbon solar cell
Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today. "Every component in our solar cell, from top to bottom, is made of carbon materials," said the study's co-lead author Michael Vosgueritchian. "Other groups have reported making all-carbon solar cells, but they were referring to just the active layer in the middle, not the electrodes."

The hunt for electron holes
Hydrogen production by solar water splitting in photoelectrochemical cells has long been considered the holy grail of sustainable energy research. Iron oxide is a promising electrode material. An international team of researchers led by Empa, the Swiss Federal Laboratories for Materials Science and Technology, have now gained in-depth insights into the electronic structure of an iron oxide electrode -- while it was in operation. This opens up new possibilities for an affordable hydrogen production from solar energy.
