Scientists created a pure hexagonal diamond in the lab, confirming a long-debated carbon structure slightly harder than natural diamonds.
A team of researchers has reported the first laboratory synthesis and recovery of bulk hexagonal diamond, a crystal form long predicted to be harder than the conventional gems used in cutting tools ...
Gas-jet deposition has emerged as a highly promising technique for the synthesis of diamond structures, employing high-velocity gas streams to activate and transport precursor species under controlled ...
