Growth of platinum clusters via addition of Pt(II) complexes: A first principles investigation

Article Abstract:

The growth of platinum clusters by the addition of Pt(II) complexes to clusters with an average oxidation state higher than zero is investigated by means of first principles molecular dynamics. The analysis of the electronic density of states of the growing clusters shows that immediately after the adsorption of the Pt(II) complexes on the cluster surface the electronic states of the complex extend over the whole cluster.

High-resolution electron microscopy of montmorillonite and montmorillonite/epoxy nanocomposites

Article Abstract:

The procedures necessary to image both the inter- and intrasheet lattice spacings in polymer/layered silicate nanocomposites are described, using a combination of high-resolution transmission electron microscopy (HREM) theory and experiment. Analysis of the radius of curvature in a stack of coherently bent intercalated morphology of montmorillonite (MMT) sheets gave a failure strain in a bending geometry of 0.033.
