New model helps define optimal temperature and pressure to forge nanoscale diamonds

Nanodiamonds, bits of crystalline carbon hundreds of thousands of times smaller than a grain of sand, have intriguing surface and chemical properties with potential applications in medicine, optoelectronics and quantum computing. To forge these nanoscopic gemstones, researchers expose organic explosive molecules to powerful detonations in a controlled environment. These explosive forces, however, make it difficult to study the nanodiamond formation process, even under laboratory conditions.
