Why do Bimetallic Clusters have more Chemical Reactivity? Study the VnNim (2 ≤ n + m ≤ 6) Clusters as the Nano Species
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=...
متن کاملStructure and local reactivity of PdAg/Pd(111) surface alloys.
Motivated by a recent detailed experimental study [Y. Ma et al., Phys. Chem. Chem. Phys., 2011, 13, 10741], the structure and local reactivity of PdAg/Pd(111) surface alloys were studied using periodic density functional theory calculations. As a probe of the local reactivity, CO adsorption energies were evaluated as a function of concentration and configuration of silver and palladium atoms an...
متن کاملEffect of Type of Surface Treatment and Adhesive System on Shear Bond Strength of Composite Resin to a Non-Precious Metal Alloy
Background and Aim: Fractured metal-ceramic restorations may be repaired with composite in some cases to postpone the fabrication of a new restoration. Knowledge about the bond strength can help predict the success rate of this treatment modality. The aim of this study was to assess the effect of two types of mechanical surface treatment of metal along with the use of different adhesive systems...
متن کاملHydroxyl capped silver-gold alloy nanoparticles: characterization and their combination effect with different antibiotics against Staphylococcus aureus
Objective(s): Metal nanoparticles (NPs) offer a wide variety of potential applications in pharmaceutical sciences due to the unique advances in nanotechnology research. In this work, bimetal Ag-Au alloy NPs were prepared and their combinations with other antibiotics were tested against Staphylococcus aureus. Materials and Methods: Firstly, Ag-Au alloy NPs with Au/Ag molar ratio of 1:1 was f...
متن کاملNanoengineered Ultralight and Robust All-Metal Cathode for High-Capacity, Stable Lithium–Oxygen Batteries
The successful development of Li-O2 battery technology depends on resolving the issue of cathode corrosion by the discharge product (Li2O2) and/or by the intermediates (LiO2) generated during cell cycling. As an important step toward this goal, we report for the first time the nanoporous Ni with a nanoengineered AuNi alloy surface directly attached to Ni foam as a new all-metal cathode system. ...
