The diamonds found inside the meteorite have a hexagonal crystal structure called lonsdaleite. This crystal structure makes the diamonds even harder than 'traditional' ones, perhaps by as much as 60%.

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, ...

Scientists have created the first sizable meteorite diamond — also known as lonsdaleite or hexagonal diamond — a material predicted to be even harder than the diamonds normally found on Earth. The ...

They realized pure hexagonal silicon by first growing nanowires made from another material, with a hexagonal crystal structure. Then they grew a silicon-germanium shell on this template.

Crystal structure of hexagonal boron nitride (h-BN) and basic characteristics of h-BN nanomechanical resonators. (a) Top view of h-BN crystal structure.

At ambient pressures, silicon nitride has a hexagonal crystal structure and sintered ceramic of this phase is opaque. Sintering is the process of forming macroscopic structures from grain material ...

Like diamond, lonsdaleite is made up of carbon atoms, but they are arranged into a hexagonal crystal structure instead of a cubic one. "Lonsdaleite is very puzzling," Asimow told Live Science.

Researchers in Europe have found a way to make silicon-germanium (SiGe) alloys emit light efficiently, a breakthrough that has the potential to revolutionize integrated silicon photonics. In that ...

Using near-infrared radiation for these applications is safer and more accurate than using ultraviolet light. But to be effective at upconversion, the crystals need to be less than 20 nm in size and ...
