There's a big diamond in the sky made by connecting the stars Arcturus, Spica, Denebola and Cor Caroli. Once found, you can ...

By Elizabeth Paton Do you care where a diamond comes from? Historically, consumers didn’t have a choice. Natural diamonds were formed billions of years ago, deep beneath the earth’s surface ...

Hexagonal SiGe, with its direct band gap ... However, unlike group III–V compound materials such as gallium arsenide (GaAs), Si and Ge, in their most common diamond cubic crystal form, zincblende (ZB) ...

The resulting diamond has a hexagonal lattice crystal structure, rather than the normal cubic structure. Hexagonal diamond (or lonsdaleite) was first brought to the attention of scientists more than ...

The synthetic hexagonal diamond exhibits high thermal stability up to 1,100°C and a hardness of 155 GPa, promising advancements in aerospace and defense industries. Chinese scientists develop ...

By adjusting the parameters of their setup, the researchers found they could get the graphene to grow into a synthetic diamond with hexagonal lattices. The first diamond made by the group was ...

James is a published author with four pop-history and science books to his name. He specializes in history, strange science, and anything out of the ordinary. A team of scientists from two ...

However, researchers say, the applications of such a hexagonal diamond (HD), known as lonsdaleite, have been “largely unexplored” due to the low purity and minuscule size of most samples obtained.

For the first time, researchers in China have synthetically produced a nearly pure hexagonal diamond, marking a significant breakthrough in materials science. Long renowned for their exceptional ...
