New sensors sniff out land mines

Article Abstract:

Researchers at Sandia National Laboratories are developing a new portable sensor that uses an ion-mobility spectrometer in detecting land mines. The sensor will have the same technology found in explosives-detection portals used in checking airline passengers. The novel device can detect and classify minute quantities of explosive molecules. Another group of researchers at Sandia is studying the development of chemical sensing technology by modeling the environmental fate and transport of explosive signature molecules.

Coating extends magnet life

Article Abstract:

Researchers at Iowa State University have developed a new coating system for rare-earth alloy such as neodymium-iron-boron or neo alloys. The coating system is said to prevent commercial neo alloys produced by high- pressure gas atomization from corroding due to humidity and high temperatures. With the coating system, the alloys become water-resistant and thermally stable up to 500 degrees C. Researchers are studying the coating system's effects on the magnetic properties of plastic magnets.
