Manufacturing Bits: Sept. 9

Whispering sensors Inspired by a whispering technology from a famous cathedral, Washington University in St. Louis and Tsinghua University in China have developed a new sensor that can detect and count nanoparticles down to 10nm and perhaps below. Researchers have devised a Raman microlaser sensor in a silicon dioxide chip. The microsensor is called a whispering gallery mode resonator (WGMR... » read more
