Washington, DC--A team led by Carnegie's Thomas Shiell and Timothy Strobel developed a new method for synthesizing a novel crystalline form of silicon with a hexagonal structure that could potentially ...

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 ...

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 ...

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.

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 ...

Hexagonal boron nitride has a layered crystalline structure in a hexagonal lattice arrangement composed of alternating boron and nitrogen atoms held together by strong covalent bonds. This structure ...

ANU Associate Professor Jodie Bradby said her team – including ANU PhD student Thomas Shiell and experts from RMIT, the University of Sydney and the United States – made nano-sized Lonsdaleite, which ...

A 40-atom gold nanocluster breaks from gold's signature dense packing, forming square atomic planes with a central channel that accelerates electron relaxation about 80x.

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 ...

For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than cubic diamonds found in nature and often used in jewelry. Hexagonal diamonds have been found at ...
