Discovery for modifying diamonds could change computing

Marc WeberPULLMAN, Wash. – A group of WSU researchers has discovered a way to modify diamonds that opens up important applications in the field of quantum computing and in radiation detection.

Kelvin Lynn, professor of physics and of mechanical and materials engineering, and his team were using very thin strips of diamond inside a particle accelerator when they made an intriguing scientific discovery — by accident. » More …

Researchers transform graphite into hexagonal diamond

Dynamic Compression Sector at Argonne National Labs Advanced Photon SourceA new study by Washington State University researchers answers longstanding questions about the formation of a rare type of diamond during major meteorite strikes.

Hexagonal diamond or lonsdaleite is harder than the type of diamond worn on an engagement ring and is thought to be naturally made when large, graphite-bearing meteorites slam into Earth.

Scientists have puzzled over the exact pressure and other conditions needed to make hexagonal diamond since its discovery in an Arizona meteorite fragment half a century ago. » More …
