OSA Journal details new liquid crystals for vehicle displays.

2016-02-11 14:31:08| Industrial Newsroom - All News for Today

"High performance liquid crystals for vehicle displays," published in Optical Materials Express, reports results of Shin-Tson Wu and colleagues, who developed 3 new liquid crystal mixtures that overcome upper and lower operation temperature limitations. According to Wu, liquid crystals should have clearing point higher than 100°C (212°F) and melting point below -40°C (-40°F). Accomplishment was brought about by mixing one dozen 3- and 4-ring compounds together with LMW compounds.

NIST calibrates quartz crystals for fusion device.

2015-11-17 14:31:11| Industrial Newsroom - All News for Today

Sandia National Laboratories’ Z Pulsed Power Facility, or "Z machine," a nuclear fusion research device located in Albuquerque, NM, is the most powerful x-ray generator in the world. In a collaboration among PML’s Radiation Physics Division, Artep Inc., and Sandia National Laboratories, set of 18 bent quartz crystals had their energy and sensitivity responses calibrated at NIST’s campus in MD. Curved crystals extend energy range of x rays that can be measured when emitted by Sandia’s Z machine.
