Two groups of X-ray methods are now widely applied to the study of environmental samples for geochemistry and pollution investigations, X-ray emission spectrometry (XRS) and X-ray diffraction (XRD), and the underlying physical principles of these methods and their limitations are well understood.

This chapter covers the preliminary characterization of the crystals in order to determine if they are suitable for a full structure determination. Probably more frustrating than failure to produce crystals at all, is the growth of beautiful crystals which do not diffract, which have very large unit cell dimensions, or which decay very rapidly in the X-

X-rays are produced whenever electrons are suddenly brought to rest by colliding with matter. It is necessary therefore, for the following conditions to prevail: 1. a means of producing and sustaining a stream of electrons, i.e. a good vacuum, with a source of electrons which in most modern X-ray tubes is a heated filament; 2.

In this paper we briefly discuss the main concept and details of X-ray Lithography, a parallel lithographic technique belonging to the domain of UV lithography (UVL). The main difference lies on its usage of X-ray photons, which having a much shorter wavelength were supposed to provide for a ‘resolution reserve’ for Moore’s law requirements, long after
