In particular, upon entrapping an otherwise unstable metal cluster into a carbon cage, the so-called endohedral clusterfullerenes fulfil the mutual stabilization of the inner metal cluster and the outer fullerene cage … Science Center to Yoshihide Hayashizaki, and by a research grant from MEXT September 21, 2016 admin Uncategorized 11.

Based on magic cluster Zn12S12, we get singular nano materials with different dimensionality (0D’s dimer and trimer, 1D’s nanowire and 2D’s nanosheet). We use essential cookies to perform essential website functions, e.g. The structure of [Mo 2 (S 2) 6] 2-cluster is: So, the bridging S 2 2- is two and co-ordination number of Mo is 8. Despite many attempts at obtaining Si clusters well suited for building blocks, the fabrication of Si cage clusters with self-complete bonding is still a challenge although carbon forms stable clusters (fullerenes). 0000074556 00000 n Fullerenes have the characteristic of a hollow interior, and this unique feature triggers intuitive inspiration to entrap atoms, ions or clusters inside the carbon cage in the form of endohedral fullerenes. 0000018680 00000 n This may take some time to load. 0000017813 00000 n 0000008821 00000 n "Reproduced from" can be substituted with "Adapted from". Plessy, Bertin, Takahashi, Simone, Definition of Promotome–Transcriptome Architecture Using CAGEscan The Zn12S12 cages can bind into various porous materials with different dimensionality by the most stable bonding HH1. Education, Culture, Sports, Science and Technology (MEXT) for the RIKEN Omics A variety of metal clusters have been reported to form endohedral clusterfullerenes, including metal nitrides, carbides, oxides, sulfides, cyanides and so on, making endohedral clusterfullerenes the most variable and intriguing branch of endohedral fullerenes. A series of nanostructures of Zinc Sulfide (ZnS), including the small ZnnSn(n = 1–15) clusters, the magic cage-like Zn12S12 and its derivants (Zn12S12-based dimers, trimers, nanowires and monolayer) were systematically investigated by using a first-principles bottom-up calculation. There are some excellent texts which deal with particular areas of the chemistry of non-metal rings, cages and clusters in great depth but, with one or two exceptions, there are no useful introductions to this topic.
