Two-dimensional metal-organic coordination networks at a Cu(100) surface are transformed to a new supramolecular structure with one-dimensional coordination character by the addition of a second organic ligand.

introduction: gutta-percha, the concrete milky juice of the sapotaceae family tree, is the most commonly used material for obturation of prepared canal space. natural 1-4 trans stereochemical structure of gutta-percha is taken to a heating- inclusion process of various organic and inorganic elements by manufacturers. the purpose of this study is to detect the presence and percentage of inorgani...

this paper reports results of a study regarding the activities of nano structure mn/γ-al2o3 and γ-al2o3 catalysts for oxidation of 2-propanol (as a model of volatile organic compound). nanostructure of catalysts was revealed using xrd, sem and tem techniques. catalytic studies were carried out in u-shaped packed bed reactor under atmospheric pressure and at the reaction temperature of 150- 500°...
