Manufacturing Bits: Aug. 5


Chemical weapon sensors Using nanoelectromechanical system (NEMS) technologies and other parts, Sandia National Laboratories has developed a tiny gas chromatograph sensor for use in detecting toxic gases and chemical weapons. Chemical identification involves the use of various instruments and systems. Larger systems are used in the lab. A portable version, called a mass spectrometer, is ava... » read more

System Bits: April 7


Ultra-efficient magnetic-field detector In a development that could lead to miniaturized, battery-powered devices for medical and materials imaging, contraband detection, and even geological exploration, MIT researchers have developed a new, ultrasensitive magnetic-field detector they say is 1,000 times more energy-efficient than its predecessors. Magnetic-field detectors, or magnetometers,... » read more
