Nano Energy
Transparent, electrically conductive network of encapsulated silver nanowires
A team headed by Professor Silke Christiansen has developed a transparent electrode with high electrical conductivity for solar cells and other optoelectronic components -- that uses minimal amounts of material. It consists of a random network of silver nanowires that is coated with aluminium-doped zinc oxide. The novel electrode requires about 70 times less silver than conventional silver grid electrodes, but possesses comparable electrical conductivity.

A cost-effective solution to tuned graphene production
Graphene has been called the miracle material but the single-atomic layer material is still seeking its place in the materials world. Now a method to make 'defective' graphene could provide the answer. Today, in the journal Nanotechnology, a team of researchers report that they have developed a simple electrochemical approach which allows defects to intentionally be created in the graphene, altering its electrical and mechanical properties and making the material even more useful.

New computer model could explain how simple molecules took first step toward life
Sergei Maslov, a computational biologist at the US Department of Energy's Brookhaven National Laboratory and adjunct professor at Stony Brook University, and Alexei Tkachenko, a scientist at Brookhaven's Center for Functional Nanomaterials, have developed a model that explains how simple monomers could rapidly make the jump to more complex self-replicating polymers. What their model points to could have intriguing implications for the origins of life on Earth and CFN's work in engineering artificial self-assembly at the nanoscale.

Reshaping the solar spectrum to turn light to electricity
Solar energy could be made cheaper if solar cells could be coaxed to generate more power. A huge gain in this direction has been made by a team of chemists at the University of California, Riverside that has found an ingenious way to make solar energy conversion more efficient. The researchers combined inorganic semiconductor nanocrystals with organic molecules to 'upconvert' photons in the visible and near-infrared regions of the solar spectrum.

Acetic acid as a proton shuttle in gold chemistry
A recently published study by Ananikov and co-workers gives a vivid example of unusual chemical reactivity found in the reactions with organogold complexes. Using the complex of modern physical methods joined with computational studies, the authors proposed reaction mechanism, where a molecule of acetic acid serves as a proton shuttle, transferring the hydrogen atom between the reaction centers.

Young scientist discovers magnetic material unnecessary to create spin current
Research at Argonne indicates that you don't need a magnetic material to create spin current from insulators--with important implications for the field of spintronics and the development of high-speed, low-power electronics that use electron spin rather than charge to carry information.

More efficient process to produce graphene developed by Ben-Gurion University researchers
Their ultra-bright lamp-ablation method surmounts the shortcomings and has succeeded in synthesizing few-layer (4-5) graphene in higher yields. It involves a novel optical system (originally invented by BGU Profs. Daniel Feuermann and Jeffrey Gordon) that reconstitutes the immense brightness within the plasma of high-power xenon discharge lamps at a remote reactor, where a transparent tube filled with simple, inexpensive graphite is irradiated.

Spintronics: Molecules stabilizing magnetism
Organic molecules allow producing printable electronics and solar cells with extraordinary properties. In spintronics, too, molecules open up the unexpected possibility of controlling the magnetism of materials and, thus, the spin of the flowing electrons. According to what is reported in Nature Materials by a German-French team of researchers, a thin layer of organic molecules can stabilize the magnetic orientation of a cobalt surface.

Penn researchers discover new chiral property of silicon, with photonic applications
By encoding information in photons via their spin, 'photonic' computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information in the spin of electrons, rather than just their quantity, could make 'spintronic' computers with similar advantages. University of Pennsylvania engineers and physicists have now discovered a property of silicon that combines aspects of all of these desirable qualities.
