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.

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.

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.

Battery second use offsets electric vehicle expenses, improves grid stability
Plug-in electric vehicles have the potential to dramatically drive down consumption of carbon-based fuels and reduce greenhouse gas emissions, but the relatively high price of these vehicles -- due in large part to the cost of batteries -- has presented a major impediment to widespread market penetration. Researchers at the Energy Department's National Renewable Energy Laboratory are playing a crucial role in identifying battery second use strategies capable of offsetting vehicle expenses while improving utility grid stability.

Autonomous taxis would deliver significant environmental and economic benefits
Imagine a fleet of driverless taxis roaming your city, ready to pick you up and take you to your destination at a moment's notice. While this may seem fantastical, it may be only a matter of time before it becomes reality. And according to a new study from Lawrence Berkeley National Laboratory, such a system would both be cost-effective and greatly reduce per-mile emissions of greenhouse gases.
