Report: Diamond 'super-earth' may not be quite as precious

A planet 40 light years from our solar system, believed to be the first-ever discovered planet to consist largely of diamond, may in fact be of less exquisite nature, according to new research led by University of Arizona astronomy graduate student Johanna Teske.

New Form of Carbon is Stronger Than Graphene and Diamond

Chemists have calculated that chains of double or triple-bonded carbon atoms, known as carbyne, should be stronger and stiffer than any known material The sixth element, carbon, has given us an amazing abundance of extraordinary materials. Once there was simply carbon, graphite and diamond. But in recent years ...

Researchers optically levitate a glowing, nanoscale diamond

Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. In a paper published this week in Optics Letters, they describe how they used a laser to trap nanodiamonds in space, and – using another laser – caused the diamonds to emit light at given frequencies.

New type of carbon is hard enough to dent diamonds

A new form of very hard carbon clusters with a rather unusual structure is so hard it dented the diamond anvil used in its creation.

Room temperature quantum bit created

Scientists have taken a big step towards practical quantum computing, with the creation of qubits that can exist in a solid-state system at room temperature.

Working quantum computer built inside a diamond

A quantum computer created inside a diamond is the first of its kind to include protection against 'decoherence' – noise that prevents it from functioning properly.

Astronomers discover a planet made of diamond

An international team of scientists has discovered a planet made of diamond after first detecting a pulsar using the Parkes and Lovell radio telescopes.

Research shows diamonds aren't forever

New research has shown that diamonds aren’t forever. Sorry ladies, the commercials are lying to you.

Silver-Diamond mix offers cool capabilities for electronics

Georgia Tech Research Institute researchers are working on a new material to help cool the microelectronics in defense systems.

The diamond as big as a planet

It's a long way to go, but it could be worth it: most of the rocks on an odd gas giant 1,200 light years away could be made of diamond, astronomers say.
