Multiple groups claim to create first atom-thick silicon sheets

(PhysOrg.com) -- Since its discovery in 2004, graphene -- sheets of carbon an atom thick -- has sparked a flurry of research into the nanomaterial's potential applications for blazing fast, tiny electronics. Now, several ...

Atom Pinhole Camera Acts as a Shrinking Copy Machine

(PhysOrg.com) -- 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 ...

New materials bring quantum computing closer to reality

For 60 years computers have become smaller, faster and cheaper. But engineers are approaching the limits of how small they can make silicon transistors and how quickly they can push electricity through devices to create digital ...

Researchers 'iron out' graphene's wrinkles

From an electron's point of view, graphene must be a hair-raising thrill ride. For years, scientists have observed that electrons can blitz through graphene at velocities approaching the speed of light, far faster than they ...

New transitory form of silica observed

A Carnegie-led team was able to discover five new forms of silica under extreme pressures at room temperature. Their findings are published by Nature Communications.
