The success of the flight test program is the result of a team of
dedicated government and contractor professionals," said Larry
Lawson, Lockheed Martin's F-35 program executive vice president and general
manager.
Materials science and engineering researchers have demonstrated for the first time the key mechanism behind how energy levels align in a critical group of advanced materials. This discovery is a significant breakthrough in the development of sustainable technologies such as dye-sensitized solar cells and organic light-emitting diodes.
A researcher is developing several technologies that could improve the performance of electric motors and generators. And that could make a real difference in building sustainable energy systems.
Researchers in California report that they have significantly enhanced polymer solar cells' performance by building a device with a new "tandem" structure that combines multiple cells with different absorption bands. The device had a certified power-conversion efficiency of 8.62 percent and set a world record in July 2011.
By depositing atoms on one side of a grid of the "miracle material" graphene, researchers ave engineered piezoelectricity into a nanoscale material for the first time. The implications could yield dramatic degree of control in nanotechnology.
Inspired by a toy, the 'buckliball' -- a collapsible structure fabricated from a single piece of material -- represents a new class of 3-D, origami-like structures.
Strains of E. coli bacteria were engineered to digest switchgrass biomass and synthesize its sugars into gasoline, diesel and jet fuel. The switchgrass, which is among the most highly touted of the potential feedstocks for advanced biofuels, was pre-treated with ionic liquid, a key to the success of this study.
