Crystallographic Methods, Principles, and Data. Third edition. By Charles S. Barrett and T. B. Massalski. (McGraw-Hill Series in Materials Science and Engineering.) Pp. xvii + 654. (London and New ...

When a liquid metal cools and turns into a solid, its atoms come together to form crystals. The structure of these crystals is not perfect. Sometimes an extra layer of atoms squeezes between other ...

A model showing how metallic bonds are formed - the first diagram shows the outer electrons in their atoms, and the second diagram shows that the electrons have become delocalised ...

The diagram shows a simple model of metallic structure. The metal ions are shown as tiny spheres, packed closely together in a regular pattern.

Metal nanoparticles are nanoscale structures composed of metals such as gold, silver, platinum, and copper. These particles typically range in size from 1 to 100 nanometers and exhibit unique physical ...

Microstructural analysis of this forged iron structure revealed an extraordinary convergence of properties that resulted in ...

and to point out that they provide interesting examples of the influence of steric hindrance on molecular structure and on the stability of metal chelates.
