Investigation of structural and electronic properties of small Au n Cu m (n+m≤5) nano-clusters for Oxygen adsorption
In this study, the structures, the IR spectroscopy, and the electronic properties of AunCum (n+m≤5) bimetallic clusters were studied and compared with those of pure gold and copper clusters using the generalized gradient approximation (GGA) and exchange correlation density functional theory (DFT). The study of an O2-AunCum system is important to identify the promotion effects of each of the two...

متن کامل$(m,n)$-algebraically compactness and $(m,n)$-pure injectivity
In this paper, we introduce the notion of $(m,n)$-algebraically compact modules as an analogue of algebraically compact modules and then we show that $(m,n)$-algebraically compactness and $(m,n)$-pure injectivity for modules coincide. Moreover, further characterizations of a $(m,n)$-pure injective module over a commutative ring are given.
متن کاملStructural, stability and electronic properties of OsmCn (m+n 7) clusters
The structures, relative stabilities and electronic properties of OsmCn clusters for m+n 7 have been investigated by the density functional theory. The planar geometries have been preferred for small carbon mixed clusters up to m+n=5, for those with size of m+n 6, the C-rich clusters are still planar structures, while Os-rich clusters are three-dimensional structures, and the most energetic fav...
