The nanocluster models were built for all the intermetallics using a recently developed algorithm implemented into TOPOS. The relations of the structures based on the 0@4@22 core are explored as a result of migration of atoms between different shells of the nanoclusters. It is shown that the 0@4@22 nanoclusters frequently occur as building units of intermetallics of different composition and structure type. Regularities in chemical composition of 702 gamma-brass-type nanoclusters were found within both the nanoclusters approach (multishell structure) and the nested-polyhedra model. A database containing all topological types of gamma-brass nanoclusters is created with which one can search for the corresponding atomic configuration in any intermetallics.  ISSN : 0020-1669  Journal Name : INORGANIC CHEMISTRY  Volume : 52  Issue Number : 22  Publishing Year : 1434 AH 2013 AD  Article Type : Article  Added Date : Monday, July 17, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email A Pankova Pankova, A Researcher     V Blatov Blatov, V Researcher     G Ilyushin Ilyushin, G Researcher     D Proserpio Proserpio, D Researcher     Files File Name Type Description  42044.pdf pdf   Back To Researches Page
