Laser mastery narrows down sources of superconductivity
Uncovering the mechanism behind high-temperature superconductivity -- a phenomenon with tremendous value to advances in energy efficiency and sustainability -- remains one of the greatest and most pressing puzzles in physics. Now, using precise laser pulses and atomically perfect 2D materials, collaborating scientists have ruled out one possible source of HTS: Fleeting fluctuations called charge-density waves.

Solar energy to get boost from cutting-edge forecasts
Applying its atmospheric expertise to solar energy, NCAR is spearheading a three-year, nationwide project to create unprecedented, 36-hour forecasts of incoming energy from the sun. The prototype system will forecast sunlight every 15 minutes over specific solar facilities, thereby enabling utilities to continuously anticipate the amount of available solar energy.

Researchers propose new way to probe Earth's deep interior
Researchers propose a new technique that might one day reveal in higher detail than ever before the composition and characteristics of the deep Earth. There's just one catch: it relies on a fifth force of nature that has not yet been detected, but which some particle physicists think might exist. If it does, this new force would connect matter at Earth's surface with matter hundreds to thousands of kilometers below, deep in Earth's mantle.

Explosives vapor detection technology: The new 'sniff test'
A quick, accurate and highly sensitive process to reliably detect minute traces of explosives on luggage, cargo or traveling passengers has been demonstrated by scientists at the Department of Energy's Pacific Northwest National Laboratory. The vapor detection technology accurately detects and identifies the vapors of even very low-volatility explosives in real time at ambient temperature and without sample pre-concentration.

Searching for the solar system's chemical recipe
The ratio of isotopes in elements like oxygen, sulfur, and nitrogen were once thought to be much the same everywhere, determined only by their different masses. Then isotope ratios in meteorites, interplanetary dust and gas, and the sun itself were found to differ from those on Earth. Planetary researchers now use Lawrence Berkeley National Laboratory's Advanced Light Source to study these "mass-independent" effects and their origins in the chemical processes of the early solar system.

New material interface improves functioning of non-silicon-based electronic devices
For the first time, researchers have designed a special material interface that has been shown to add to and to improve the functioning of non-silicon-based electronic devices, such as those used in certain kinds of random access memory. The new method could be used to design improved, more-efficient, multilevel and multifunctional devices, as well as enhanced nanoelectronic components -- such as non-volatile information storage and processing; and spintronic components

Dopants dramatically alter electronic structure of superconductor
Study demonstrates that doping dramatically alters the atomic-scale electronic structure of the parent of a high-temperature superconductor, with important consequences for the behavior of the current-carrying electrons. The findings could potentially point to new ways to design superconductors with improved properties.

Synthetic molecule first electricity-making catalyst to use iron to split hydrogen gas
To make fuel cells more economical, engineers want a fast and efficient iron-based molecule that splits hydrogen gas to make electricity. Online Feb. 17 at Nature Chemistry, researchers report such a catalyst. It is the first iron-based catalyst that converts hydrogen directly to electricity. The result moves chemists and engineers one step closer to widely affordable fuel cells.

In the blink of an eye: X-ray imaging on the attosecond timescale
Berkeley Lab's Ali Belkacem has been using powerful laboratory-scale lasers to test whether multidimensional nonlinear x-ray spectroscopy on the attosecond timescale is practical for the light sources of the future -- and just what combination of beam characteristics is needed to define them. He'll discuss his work as part of the panel session titled "Attosecond Science in Chemical, Molecular Imaging, Spintronics, and Energy Science."

Rutgers physicists test highly flexible organic semiconductors
Rutgers University physicists have demonstrated extremely flexible organic semiconductors that withstood multiple bending cycles in which the devices were rolled to a radius as small as 200 micrometers. The technology holds promise for making low-cost flexible electronics -- conceivably video displays that bend like book pages or roll and unroll like posters, or wearable circuitry sewn into uniforms or athletic wear.
