The same properties that make engineered nanoparticles attractive for numerous applications — small as a virus, biologically and environmentally stabile, and water-soluble — also cause concern about their long-term impacts on environmental h…
A new chemical analysis technique developed by a research group at the National Institute of Standards and Technology (NIST) uses the shifting ultrasonic pitch of a small quartz crystal to test the purity of only a few micrograms of material. …
NIST will use the new ultra-dark detector, described in a new paper in Nano Letters,* to make precision laser power measurements for advanced technologies such as optical communications, laser-based manufacturing, solar energy conversion, and in…
