A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

Diamond is famously known as the hardest mineral on Earth. “There are hundreds of claims from people who believe they have seen it,” says Oliver Tschauner, a mineralogical crystallographer at the ...

Researchers are analyzing the new find at the mine in northern Botswana and paying attention to a quality never before documented.

Single-crystalline diamond nanowires embedded with platinum nanoparticles were fabricated for high-temperature solar-blind photodetection. At room temperature, the photodetector's responsivity ...
