Borophene, graphene’s lesser-known cousin, advances as 2D materials platform

By Lisa McDonald / March 22, 2019

Borophene, a 2D sheet of boron atoms, is extremely flexible, strong, and lightweight—even more so than graphene, its carbon-based cousin. Researchers at Brookhaven National Laboratory and Yale University have succeeded in growing large-area sheets of borophene for the first time.

Video: Search for an ideal anti-fog coating “heats” up the competition

By Lisa McDonald / March 20, 2019

ETH Zurich researchers developed an anti-fog coating that works by absorbing sunlight and generating heat rather than being hydrophilic, like other common anti-fog sprays. The researchers are collaborating with an industry partner to bring their coating to market.
