More efficient and reliable refrigerators and air conditioners a step closer
Scientists at Research Triangle Institute in North Carolina have created the world?s first working device that uses nanometer-scale materials to convert electric power into cooling or heating, or heat into electricity. Among its many potential applications, the development could eventually lead to more reliable solid-state refrigerators and air conditioners, and more efficient and compact power sources, according to the researchers.
NASA to Develop Biohazard ‘Smoke’ Detector
Researchers at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., have demonstrated a prototype device that automatically and continuously monitors the air for the presence of bacterial spores. The result is a novel alarm capability reminiscent of smoke detectors. Current methods for detecting bacterial spores, such as anthrax, require a trained operator. The large number of trained monitors required, with associated costs, limits widespread implementation of these methods.
