Less radiation in inner Van Allen belt than previously believed
The inner Van Allen belt has less radiation than previously believed, according to a recent study in the Journal of Geophysical Research. Observations from NASA's Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.

'Flying saucer' colloidal quantum dots produce brighter, better lasers
A multi-institutional team of researchers from Canada and the US has demonstrated steady state lasing with solution-processed nanoparticles called 'colloidal quantum dots,' an important step on the path to improving laser tools for fiber optics, video projectors and more accurate medical testing technology. The work is reported today in a paper for the journal Nature.

Study IDs link between sugar signaling and regulation of oil production in plants
Scientists from Brookhaven Lab have identified a previously unknown link between a protein that maintains plant sugar balance and one that turns on oil production. The biochemical detective work points to new strategies for tapping into the energy plants capture from the sun to produce oil-based biofuels and other biomaterials.

Perovskite edges can be tuned for optoelectronic performance
In the eternal search for next generation high-efficiency solar cells and LEDs, scientists at Los Alamos National Laboratory and their partners are creating innovative 2-D layered hybrid perovskites that allow greater freedom in designing and fabricating efficient optoelectronic devices. Industrial and consumer applications could include low cost solar cells, LEDs, laser diodes, detectors, and other nano-optoelectronic devices.

Guiding light: Sandia creates 3-D metasurfaces with optical possibilities
The new Sandia metamaterials can be fabricated in multiple layers to form complex, three-dimensional meta-atoms that reflect more light than shiny gold surfaces, usually considered the ultimate in infrared reflectivity. The III-V materials also emit photons when excited -- something that silicon, which can reflect, transmit and absorb -- can't do.

Small nanoparticles have surprisingly big effects on polymer nanocomposites
Polymer nanocomposites mix particles billionths of a meter in diameter with polymers, which are long molecular chains. Often used to make injection-molded products, they are common in automobiles, fire retardants, packaging materials, drug-delivery systems, medical devices, coatings, adhesives, sensors, membranes and consumer goods. When a team led by Oak Ridge National Laboratory tried to verify that shrinking the nanoparticle size would adversely affect the mechanical properties of polymer nanocomposites, they got a big surprise.

Plants at the pump
Regular, unleaded or algae? That's a choice drivers could make at the pump one day. Toward that goal, Sandia National Laboratories is testing strains of algae for resistance to a host of predators and diseases, and learning to detect when an algae pond is about to crash.

ORNL study examines tungsten in extreme environments to improve fusion materials
'We're trying to determine the fundamental behavior of plasma-facing materials with the goal of better understanding degradation mechanisms so we can engineer robust, new materials,' said materials scientist Chad Parish of Oak Ridge National Laboratory. He is senior author of a study in the journal Scientific Reports that explored degradation of tungsten under reactor-relevant conditions. Learning about how energetic atomic bombardment affects tungsten microscopically helps engineers improve nuclear materials.

New materials could turn water into the fuel of the future
Scientists at Berkeley Lab and Caltech have -- in just two years -- nearly doubled the number of materials known to have potential for use in solar fuels. They did so by developing a process that promises to speed the discovery of commercially viable generation of solar fuels that could replace coal, oil, and other fossil fuels.
