Photonic radiation sensors survive huge doses undamaged

Researchers at the National Institute of Standards and Technology (NIST) have published landmark test results that suggest a promising class of sensors can be used in high-radiation environments and to advance important medical, industrial and research applications. Photonic sensors convey information with light instead of electric currents in wires. They …

A new way to measure nearly nothing

Many semiconductor fabricators and research labs are under increasing pressure from, of all things, vacuum. These facilities need to remove greater amounts of gas molecules and particles from their setups as new technologies and processes demand lower and lower pressures. For example, the vacuum chambers in which microchip manufacturers lay …

NIST method measures 3D polymer processing precisely

Recipes for three-dimensional (3D) printing, or additive manufacturing, of parts have required as much guesswork as science. Until now.  Resins and other materials that react under light to form polymers, or long chains of molecules, are attractive for 3D printing of parts ranging from architectural models to functioning human organs. …
