A simple relation is derived between the compressibility and absorption frequency of ionic crystals. This relation takes into account the change which a displacement induces in the electronic ...

Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 (1,200,000,000,000,000,000) ions. The lattice arrangement continues in three dimensions.

A chemical compound used to stabilize particles in suspension has proved capable of controlling the growth of ice crystals, according to researchers in France. Surprisingly, the compound in question ...

A growing body of evidence from the analysis of biominerals 1,2, the crystallization of ionic compounds 3,4,5,6 and proteins 7,8,9,10, colloidal assembly 11,12 and nanocrystal synthesis 13,14,15 ...

The study of crystal growth and characterisation of fluorite-like compounds has garnered significant attention owing to their unique structural features and promising functional properties. These ...

The theory of the thermoelectric power of solid ionic conductors has been considered thermodynamically by Holtan, Mazur & de Groot (1953) and kinetically by Howard & Lidiard (1957a,b). In the ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

Whereas π-stacking systems involving aromatic compounds are quite common, those made from antiaromatic units are rare. In a recent study, researchers from Japan developed modified norcorrole molecules ...
