Engineers Envision Cheaper Algae Oil Production

Compared to soybeans that produce 50 gallons of oil an acre a year, some algae can average 6,000 gallons - but it's not cheap to produce. Two Kansas State University engineers are assessing systematic production methods that could lower the costs of algae oil production. They plan to grow algae in the ocean on very large, supporting platforms.

Lattice-Matched Semiconductor Layers on Single Crystalline Sapphire Substrate

SiGe is an important semiconductor alloy for high-speed field effect transistors (FETs), high-temperature thermoelectric devices, photovoltaic solar cells, and photon detectors. The growth of SiGe layer is difficult because SiGe alloys have different lattice constants from those of the common Si wafers, which leads to a high density of defects, including dislocations, micro-twins, cracks, and delaminations.

Harvesting Energy from Regular, Day-to-Day Motions

Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life. Although motion is an abundant source of energy, only limited success has been achieved because the devices used only perform well over a narrow band of frequencies.
