Lockheed Martin’s Hybrid Air Vehicle can transport people or cargo to any type of landing area, or can act as an “eye in the sky,” staying aloft for up to three weeks at an altitude of 20,000 feet.

Identifying defects in LEDs improves performance

Using state-of-the-art theoretical methods, University of California, Santa Barbara, researchers identified a specific type of defect in the atomic structure of an LED that results in less efficient performance.

Halogen atoms shed light on solar cell efficiency

Researchers at the Department of Energy’s Oak Ridge National Laboratory found a potential path to further improve solar cell efficiency by understanding the competition among halogen atoms during the synthesis of sunlight-absorbing crystals.
