Custom silica, silica-titania inks offer new possibilities for 3-D-printed optical glass

By Faye Oney / April 6, 2018

Researchers at Lawrence Livermore National Laboratory have broken the “3-D printed glass barrier” by developing a direct ink writing method to 3-D print optical glass that uses silica and silica titania from sol-gel.

Lucideon is aiming high with nanoporous ceramic pills intended to prevent abuse of painkillers

By April Gocha / February 1, 2016

Materials science company Lucideon has developed a new strategy that can prevent drug abusers from using dangerous methods to get high—the company’s ceramic pills are much more structurally robust than traditional pharmaceuticals, making them very difficult to crush or to dissolve into alcohol or other solvents.

Transformed aerogels: From amorphous carbon to nanocrystalline diamond

By Eileen De Guire / June 1, 2011

Laser-heated diamond anvil cell allows very large hydrostatic pressure to be applied to amorphous carbon aerogels. Cavity dimensions are approximately 100–170 μm wide by 35 μm thick. Credit: LLNL. While there has been considerable interest in capturing the properties of diamond in a low-density form, converting an amorphous carbon aerogel to a crystalline phase without…
