Is it canard?
WASHINGTON, Feb. 25 (UPI) -- Scientists at Carnegie Institution''s Geophysical Laboratory in Washington claim to have created gem-sized diamonds harder than any other crystals.
The researchers created the diamonds from a gas mixture in one day -- at a rate that is up to 100 times faster than other methods used to date.
"We believe these results are major breakthroughs in our field," said Chih-shiue Yan. "Not only were the diamonds so hard that they broke the measuring equipment, we were able to grow gem-sized crystals in about a day."
The scientists developed a special high-growth rate chemical vapor deposition process to create the cystals that were then subject to high-pressure and high-temperature treatments.
"This has opened up an entirely new way of producing diamond crystals for a variety of applications, such as the next generation diamond-based electronics devices and cutting tools," said Russell Hemley.
The study was published in the Feb. 20, online Physica Status Solidi.
