Short wavelength plasmons observed in nanotubes
Working at the Advanced Light Source, Berkeley Lab researchers have observed 'Luttinger-liquid' plasmons in metallic single-walled nanotubes. This holds great promise for novel plasmonic and nanophotonic devices over a broad frequency range, including telecom wavelengths.

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.

UT Dallas nanotechnology research leads to super-elastic conducting fibers
A research team based at the University of Texas at Dallas has made electrically conducting fibers that can be reversibly stretched to over 14 times their initial length and whose electrical conductivity increases 200-fold when stretched. In a study published in the July 24 issue of the journal Science, the scientists describe how they constructed the fibers by wrapping electrically conductive sheets of carbon nanotubes to form a jelly-roll-like sheath around a long rubber core.

ORNL researchers make scalable arrays of 'building blocks' for ultrathin electronics
For the first time, researchers at the Department of Energy's Oak Ridge National Laboratory have combined a novel synthesis process with commercial electron-beam lithography techniques to produce arrays of semiconductor junctions in arbitrary patterns within a single, nanometer-thick semiconductor crystal. The process transforms patterned regions of one existing, single-layer crystal into another. The two semiconductor crystals formed sharp junctions, the desired building blocks of electronics. Nature Communications reports the accomplishment.

Simulations lead to design of near-frictionless material
Argonne scientists used the Mira supercomputer to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. ALCF researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code.

An easy, scalable and direct method for synthesizing graphene in silicon microelectronics
Graphene has been studied intensively for its unique properties, and now researchers have developed a microelectronics-compatible method to grow it and have synthesized wafer-scale, high-quality graphene on silicon substrates. The method is based on an ion implantation technique, a process in which ions are accelerated under an electrical field and smashed into a semiconductor. In Applied Physics Letters, the researchers describe their work, which takes graphene a step closer to commercial applications in silicon microelectronics.

Rock paper fungus
Believe it or not: X-ray works a lot better on rocks than on paper. This has been a problem for conservators trying to save historical books and letters. They frankly did not know what they were up against once fungi started to spot the surface of their documents. Now Diwaker Jha, an imaging specialist from Department of Chemistry, University of Copenhagen, has managed to get a first look at how fungus goes about infesting paper.
