Progress in the discovery of new materials has been accelerated by the development of reliable quantum-mechanical approaches to crystal structure prediction. The properties of a material depend very sensitively on its structure; therefore, structure pred
Structure and Bonding 2.5 BODY CENTERED CUBIC STRUCTURE The coordination number of first nearest neighbors in closed packed structures is 12. Nevertheless, several metals crystallize in the body centered cubic structure (W type, Pearson symbol cI2, Figure 2.5). The coordination number is reduced to ...

The structure of liquid carbon elucidated by in situ X-ray diffraction A precise structure measurement of liquid carbon at pressures of around 1 million atmospheres obtained by in situ X-ray diffraction at an X-ray free-electron laser shows a complex fluid with transient bonding and approximately...
However, bonding in ceramics is not simply ionic or covalent. In actuality, the bonding in ceramics crosses a spectrum from ionic to covalent, with different degrees of the extent of ionic and covalent character from material to material; for example, MgO is 73% ionic. The properties of a ...
