The second English edition is largely based on the third German edition of the Teubner Studienbuch “ Kristallstrukturbestimmung,” which appeared in 2002. In particular, Chapter 7, dealing with experimental methods, has been extensively rewritten. In view of the huge recent advances in the use of area detector systems for single-crystal data collection, their description has replaced much of the...
The microstructure of gold catalysts supported on rutile was obtained by Rietveld refinement. Three-dimensional images of the crystallites were generated in real space, as well as 3-D images of the microstrain distribution in reciprocal space. These images were used to analyze the effect of the different parameters of the refinement models on the interpretation of the microstructure of the samp...
During investigations of phase transformation kinetics by diffraction techniques, several hundreds or even thousands of diffraction patterns are collected. Automation of the data analysis process is mandatory to perform for example a long sequence of Rietveld refinements. The Bragg edge transmission (BET) technique, a neutron time-of-flight method, allows acquiring patterns of sufficient statis...
The raw materials obtained from the Earth’s crust (Geomaterials) are of fundamental importance for a wide range industries [...]
