This manuscript reports the simultaneous electrodeposition of Cu and Rh from an aqueous nitrate solution. The early stages nucleation growth bimetallic layer were explored using techniques such as cyclic voltammetry current transients. Non-dimensional Scharifker-Hills graphs showed occurrence diffusion-controlled three-dimensional best described by Volmer-Weber mechanism. Additionally, differen...

This article gives you proof that bimetallic transition metal clusters with the difference in electronegativity are better catalysts than monoatomic one. To prove this fact, a study of ethylene adsorption on bimetallic clusters vanadium-nickel VnNim (2≤n+m≤6) has been demonstrated. Our result shows that hardness has a quite good linear correlation with the non-Lewis of VnNi (n=1-5) cluster (R2=...

Chromium-vanadium (Cr-V) bimetallic catalysts are prepared by the introduction of vanadium into the Phillips catalyst which is one of the most significant industrial ethylene polymerization catalysts for tuning the Phillips catalyst performances and improving polyethylene properties. In the present work, titanium species were introduced into the fluorine-modified chromium-vanadium bimetallic ca...

Dealloyed Pt core-shell nanoparticles constitute the most active and stable bimetallic oxygen reduction catalysts for low-temperature fuel cells. Here, we review recent advances on their preparation, structural characterization, and electrocatalytic performance. Starting with bimetallic metal overlayer model systems, for which we illustrate fundamental principles of the ORR activity enhancement...

We have prepared supported gold, palladium and gold–palladium bimetallic catalysts by the physical mixing of the acetate salts of the metals followed by a simple heat treatment. The use of the acetates as the metal precursor eliminates chloride from the catalyst preparation step. Extensive characterisation shows the formation of bimetallic alloy particles. These catalysts are extremely active f...

The Skellefte mining District is located in northern Sweden and comprises Palaeoproterozoic, metamorphosed, supracrustal rocks and associated intrusive rocks, which are all host to several ore deposits. Modelling was performed in the GoCAD software platform, using structural geology and petrology as well as magnetic, gravity, seismic, electric and electromagnetic geophysical data, in order to p...

This paper summarises the use of digital remotely sensed data for Quaternary deposits mapping in central Sweden. Landsat TM scene of the beginning of May 1985 was applied. Only six groups of quaternary deposits were distinguished. The classification accuracy of the resultant map was about 50 % in average. Comparison was done with the existing map of Quaternary deposits.

The combination of (High-resolution) electron microscopy, Selected Area Diffraction and X-ray Diffraction was applied to study the structural, compositional and morphological alterations of two Pd/Ga2O3 catalysts relevant for methanol steam reforming upon different oxidative and reductive treatments. These systems include well-defined Pd particles grown epitaxially on vacuum-cleaved NaCl(001) s...
