Nanocrystals Could Aid in Solid-State Lighting and CO2 Storage

Scientists at Berkeley Lab have created non-toxic magnesium oxide nanocrystals whose size can be adjusted within just a few nanometers. The nanocrystals glow blue when exposed to ultraviolet light, and could be a bright candidate for lighting that consumes less energy and has a longer lifespan. The nanocrystals could also allow researchers to probe a key pathway in carbon dioxide sequestration.
