Direct space methods of structure determination from powder diffraction: principles, guidelines and perspectives
In the last twenty five years structure determination from powder diffraction has evolved from a complex, time-consuming method to one easily usable...

03/2007 | Zeitschrift für Kristallographie, Oldenbourg WissenschaftsverlagApplication of the apparent lattice parameter to determination of the core-shell structure of nanocrystals
In this review work we discuss applicability of Bragg scattering to examination of nanocrystals. We approximate the structure of nanograins by a commonly accepted core-shell model...
