Building better electron sources with graphene

Photocathodes that produce electron beams for electron microscopes and advanced accelerators can be refreshed and rebuilt repeatedly without opening the devices that rely on them, provided the electron emitting materials ...

Researchers design novel antibiofouling biomimetic diamond film

Biofouling is a worldwide problem that leads to severe deterioration after a substrate comes into contact with seawater. Traditional polymers and other antifouling coatings suffer from poor mechanical and chemical stability, ...

Manipulating metals for adaptive camouflage

Many species have naturally evolved remarkable strategies to visually adapt to their environments for protection and predation. Researchers have studied adaptive camouflaging in the infrared (IR) spectrum, although the method ...
