They’ve invented photomasks containing tiny, transparent pipes into which the engineers have injected dyes that dim the ultraviolet (UV) radiation passing through. Where less UV light penetrates ...

with funding from the U.S. Office of Naval Research (ONR), developed biofilm-resistant glass using UVC radiation, the shortest and most effective at disinfecting wavelength of UV radiation.

It is an amorphous commodity thermoplastic that can be colorless and transparent but is ... with relatively good chemical resistance (solvents are its weak area, particularly stress cracking therein).
