Metal clusters and nanoparticles.
By the 1980s, this field had matured, but a renaissance occurred with the availability of more advanced and sophisticated physical methods used to characterise such compounds. This renaissance can also be traced back to the rediscovery of colloid chemistry as well as to the realisation that metal-rich cluster complexes can be considered as a bridge between classical small metal complexes of the...
متن کاملMetal clusters inside out.
Solid-state chemistry of cluster compounds with metals in the left part of the periodic table is described. As a function of the metal valence electron concentration (VEC), characteristic changes occur with stepwise changing features. Strongly metal-metal-bonded and ligand-encapsulated clusters exist for large values of VEC. At decreased values, endohedral atoms stabilize the clusters, and with...
متن کاملresponse articles: micro and macro analysis
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...

There is still no sharp discrimination between the terms ‘cluster’ and ‘nanoparticle’ in the literature. Clusters are mostly considered as species, exactly defined in chemical composition and structure, whereas the expression ‘nanoparticle’ usually means particles of less precise characterization, often linked with a certain size distribution and so to some extent substitutes the historical exp...
متن کاملExperimental and computational studies of alkali-metal coinage-metal clusters.
Coinage and alkali metal mixed clusters, M4Na- (M = Cu, Au) have been investigated experimentally using photoelectron spectroscopy and computationally at correlated ab initio levels. The related Cu4Li-, Ag4Li-, Ag4Na-, and Au4Li- clusters as well as the neutral Cu4Li2 and Cu4Na2 clusters have also been studied computationally. The calculations show that the two lowest isomers of the negatively ...
