ZT 16 - Dynamics of nanocrystal structure induced by surface chemistry (Z.Kaszkur)


The group engages in studies of nanocrystal structure and dynamics of its change during chemical reaction and other physico-chemical processes.  The studied materials are mostly catalysts with focus on the structure of small metallic nanoclusters. The developed methods allow detection of surface reconstruction of metal nanocrystals, monitoring of surface segregation phenomena in nanoalloys and interpretation of non periodic structures like icosahedra. The key developements include new method of analysis of diffraction pattern series and new ways of the pattern evolution interpretation- reaching beyond Bragg's law and employing large scale atomistic simulations.

The Group activity in instrumental part overlaps with activities of the Laboratory of X-Ray Powder Diffractometry and Spectrometry  .
