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.

Discovery in new material raises questions about theoretical models of superconductivity
The US Department of Energy's Ames Laboratory has successfully created the first pure, single-crystal sample of a new iron arsenide superconductor, CaKFe4As4, and studies of this material have called into question some long-standing theoretical models of superconductivity.

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.

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.
