The electrodeposition of a Ag/Cd ultrathin film on a Au(1 1 1) surface and the formation of a surface alloy during this process have been studied using classical electrochemical techniques and in situ Scanning Tunneling ...

The formation of an ultrathin bilayer of Ag/Cd in the system Au(111)/Ag+,Cd2+,SO2 2/4 has been studied by conventional electro-chemical techniques and in situ scanning tunneling microscopy (STM). Cyclic voltammetric ...

Active subaerial geothermal systems are regarded as modern analogues of low- to intermediate-sulfidation epithermal Au–Ag deposits, where minor amounts of Cu are mostly present as chalcopyrite. Although trace element ...

Las nanopartículas metálicas (NPsM), específicamente, las nanopartículas de oro (NPsAu) y las nanopartículas de plata (NPsAg), exhiben excelentes propiedades físicas, químicas y biológicas, intrínsecas a su tamaño ...

The Pingüino vein system forms part of the low-sulfidation epithermal mineralization associated with the Deseado Massif, Patagonia, Argentina. The ores are complex, with high tenors of Zn, Pb, Ag, Cd, Au, As, Cu, Sn, W and ...

The Jurassic Au-Zn mineralization at El Faldeo district is hosted mainly in felsic volcanic and subvolcanic rocks. Early epithermal gold mineralization is related to silicic alteration and deposition of pyrite, arsenopyrite, ...

The Patricia ore deposit represents an unusual example of economic Zn-Pb-Ag mineralization at the northernmost end of the Late Eocene-Oligocene metallogenic belt in Chile. It is hosted by volcano-sedimentary units, which ...
