New LED packaging technology improves performance

(—Many researchers have reported improvements in LED technology by enhancing the properties of the LED itself. But the packaging that secures and protects the LED also impacts its overall performance. In a new ...

Atom Pinhole Camera Acts as a Shrinking Copy Machine

( -- In 1983, Richard Feynman proposed the idea of a machine that could create smaller scale replicas of itself. Today, such a system is still a challenge, but a machine that can produce nanometer-sized copies ...

Chemists make new silicon-based nanomaterials

Chemists from Brown University have found a way to make new 2-D, graphene-like semiconducting nanomaterials using an old standby of the semiconductor world: silicon.
