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

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

A team of physicists, materials scientists and engineers affiliated with several institutions in China, working with a colleague from Umeå University, in Sweden, has grown a diamond that is harder ...

Researchers made small, pure samples of the elusive mineral lonsdaleite – also known as hexagonal diamond — and tested its ...

Researchers in China have made what they claim to be the first samples of pure hexagonal diamond, a theorised rare variant of ...

A collaborative group of researchers has potentially developed a means of controlling spin waves by creating a hexagonal pattern of copper disks on a magnetic insulator. The breakthrough is expected ...

In brief: Chinese researchers have developed a synthetic diamond that is significantly harder and more resilient than those that occur naturally here on Earth. If commercially viable, the new diamond ...
