Hexagonal diamonds are formed when graphite is subjected to strong impact and heat, such as due to a meteorite impact. While ordinary diamond has a structure called cubic, hexagonal diamond is ...

Through high pressure processing techniques performed in a symmetric diamond anvil cell, a group of researchers from the Department of Geological Sciences at Stanford University have successfully ...

The conventional view among scientists about how ice forms is that it begins from seeds in which water molecules are packed together in a hexagonal structure and maintains this structure as it grows.

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, whose hardness could surpass that of conventional diamonds, opens new ...

2D hexagonal boron nitride (h-BN) is a promising material that can undergo transition to strong, super lightweight films. Researchers have discovered that h-BN in layered, molecule-thin 2D sheets can ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Currently, diamond is regarded to be one of the hardest and most ...

In chemistry, structure is everything. Compounds with the same chemical formula can have different properties depending on the arrangement of the molecules they’re made of. And compounds with a ...

New research indicates that a rare form of diamond may originate in the burbling cores of distant worlds, arriving on Earth thanks to violent cosmic collisions. According to a team of scientists in ...

Cubic core: what is the crystal structure of iron at the centre of the Earth? (Courtesy: shutterstock/Johan Swanepoel) A long-standing debate about the structure of solid iron at the centre of the ...

The University of Cambridge, Plessey Semi and Anvil Semi have got together to apply a new material to lighting LEDs – cubic GaN, also known as 3C GaN. The standard material for lighting LEDs is GaN ...
