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 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 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 ...

Positron, the antiparticle of electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of ...

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 ...

Fast ionic transport in microporous activated-carbon electrodes is a prerequisite for the effective energy storage in electrochemical supercapacitors 1,2. However, the quartz-crystal microbalance ...

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 ...
