Method for Providing Semiconductors Having Self-Aligned Ion Implant

Refined self-aligned ion implantation for improved SiC high-temperature transistors. John H. Glenn Research Center, Cleveland, Ohio This is a modification to technology for realizing durable and stable electrical functionality of high-temperature transistors. This modification is believed crucial to experimental implementation of SiC junction field effect transistors that electrically operated continuously at 500 °C for over 10,000 hours in an air ambient with less than 10% change in operational transistor parameters.

Femtosecond Laser Processing of Metal and Plastics

Precision machining can be achieved with no thermal affects and minimal post-processing. Amada Miyachi America, Monrovia, California and Jenoptik, Jena, Germany While precise and fast, the down side to cutting with microsecond (ms) fiber lasers has been that the parts require a number of post-processing operations after they are cut, which add significantly to part cost, and can also damage mechanically delicate parts.

Simulation of Microfluidic Devices Using COMSOL

Modeling and simulation form a systematic framework for developing and optimizing microfluidic systems. Such simulations often involve coupling multiple physical effects such as single- and multi-phase flow, mixing, dispensing, heat transfer, species transport and diffusion, chemical reactions, surface tension and wetting, electrokinetic effects, and flow interaction with biological material.

NASA Spinoff: NASA’s UV Radiation Research Keeps Sun Worshipers Safe

Studying radiation effects on spacecraft led to a personal Sun exposure monitor. To understand the Sun’s impacts on Earth, NASA initiated the Living with a Star program in 2001, and began developing a key research satellite: the Solar Dynamics Observatory (SDO). One of the instruments created for the SDO was the Extreme Ultraviolet Variability Experiment (EVE), tasked with measuring extreme ultraviolet (UV) radiation, which plays a key role in atmospheric heating and satellite drag. In 2005, Goddard Space Flight Center scientist Shahid Aslam joined other researchers in developing EVE.
