Recenzje

"Dinnebier, Leineweber and Evans have done an outstanding job of explaining the fundamentals of the method and summarizing the exciting new developments. With this book, the reader can find answers to two questions: what information is stored in a powder diffraction pattern, and how to extract that information using TOPAS. I particularly like this combination of theory and practice and I wholeheartedly recommend this excellent read to any user of the powder diffraction method."
