Hello, does anyone know a good concise basic introductory book or other kind of source or course where I can find a good introduction to XRD with applied solved problems? My field of research is Heterogeneous Catalysis and I am starting a new project in which we have to use a powder xrd system to characterize catalysts like M/Zeolites (Ni, Pd, etc) with a modified pore structure. I need some background to start working. Thanks a lot!
