Application of the two-dimensional lateral microanalysis by SIMS and EPMA in materials research

Summary Possibilities of the measurement of elemental maps and their digital processing are demonstrated. Hardware and software developments and some applications for various material problems are discusses.     

Thermal analysis as a tool for investigations in metal oxide chemistry

Applications of thermoanalytical methods for the controlled preparation of metal oxides from various initial compounds (‘precursors’) as well as for investigations of physical properties and the chemical behaviour of oxidic phases as function of temperature and atmosphere are presented. Studies elucidating the course of such processes yield important contributions to the understanding of the reactivity of solids in general. Moreover, they are, e.g. in the field of heterogeneous catalysis, of practical relevance. It is shown, however, that the capability of mere thermal analysis suffers from limitations which have to be overcome by using additional, independent methods such as X-ray diffraction as well as light and electron microscopy.

Infinitesimale Deformationen von Diedersingularitäten

Denote by T¹ the vector space of infinitesimal deformations of a dihedral singularity of type D_{n, q}. Using Pinkham's method for quotient surface singularities we prove a formula for dim T¹.
