A Practical Approach to Low Temperature Microscopy and X-Ray Microanalysis

Abstract

Abstract Water is the most abundant and most important molecule in the hydrosphere, outer lithosphere and the biosphere of our planet. It is also the most abundant and energetically the least expensive building block of living material, forms an integral parts of natural inorganic matrices such as soil and is a constituent of many synthetic organic materials such as paints and polymers. Paradoxically, water does not exist naturally, in the pure state. Water, when converted to the solid state, can provide the perfect matrix in which we may observe the structure and study the in situ chemistry of hydrated samples. We will consider the nature of this solid matrix, and its constituent components in a range of sample, and show how it may be formed, manipulated, examined and analysed. In the short amount of time and space available, one can do little more than highlight the main features of the subject.
