High pressure since P. W. Bridgman - A personal view

Abstract

In this paper an attempt is made to review high pressure research over the past three or four decades from a personal viewpoint. Focus is first on two technical developments; the introduction of shock wave techniques in solids, and the extension of the static pressure range by a factor of 20–30.

The major emphasis is on the introduction of high pressure into the mainstream of modern science through the concept that pressure is a powerful, indeed an essential tool in understanding molecular and electronic properties of matter. These properties are classified under the headings (q) structure (x-rays) (b) molecular dynamics (c) pressure tuning spectroscopy (d) chemical and electronic rate phenomena (e) chemical synthesis.

Key Words:

• shockwaves
• pressure range molecular dynamics
• pressure tuning
• reactions
