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

Atomic structure of the hexagonal diamond. Image from the study. Researchers named it lonsdaleite, after crystallographer ...

A research team co-led by Professor Yang Lu from the Department of Mechanical Engineering, Faculty of Engineering, The University of Hong Kong (HKU), and Professor Chengming Li from the Institute for ...

A diamond purchase in Egypt is rarely just a purchase. It is an engagement milestone, a family keepsake in the making, and, ...

Tiny diamond particles can help fabric release heat—and despite being diamonds, they’re surprisingly affordable to make. On a hot day, most clothing traps heat. But fabric coated with ...

Carbon forms the graphite in pencils, the diamonds in jewelry and the molecules that make up every living thing. But under extreme conditions—like the heat and pressure of intense explosions—carbon ...

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

Diamond wafer prepared using the customized microwave plasma chemical vapor deposition (MPCVD) method. A research team co-led by ...

The findings further hint that space rocks may have brought the building blocks of RNA and DNA to Earth long ago ...

For more than a century, condensed matter physics has grappled with one of its greatest unsolved challenges: how to build superconductors that operate at room temperature and transmit electricity with ...

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

Researchers use supercomputers and artificial intelligence to predict how carbon transforms under extreme heat and pressure, paving the way for revolutionary materials.
