Protonation of Propene on Silica-Grafted Hydroxylated Molybdenum and Tungsten Oxide Metathesis Catalysts: A DFT Study

Theoretical assessment of the protonation reaction in the activation of propene on hydroxylated Mo(VI) and W(VI) metathesis catalysts is presented in this paper using the density functional theory calculations and five support clusters varying from simple SiO4H3 clusters to a large Si4O13H9 cluster. The bond distances and thermochemical...

Comparison of doped combination zirconium-tungsten, zirconium- molybdenum and molybdenum-tungsten on single-wall vanadium oxide nanotube in hydrogen gas adsorption

In this study, doped vanadium oxide nanotubes were evaluated using different software to study the absorption of hydrogen gas. Vanadium oxide nanotubes are one of the options for absorption and storage hydrogen gas. In this research study for the first time, the Monte Carlo simulation was used to investigate the hydrogen gas absorption behavior in molybdenum-tungsten, molybdenum-zirconium and z...

Process Control of Atomic Layer Deposition Molybdenum Oxide Nucleation and Sulfidation to Large-Area MoS2 Monolayers

Recent advances in the field of two-dimensional (2D) transition metal dichalcogenide (TMD) materials have indicated that atomic layer deposition (ALD) of the metal oxide and subsequent sulfidation could offer a method for the synthesis of large area two-dimensional materials such as MoS2 with excellent layer control over the entire substrate. However, growing large area oxide films by ALD with ...

Switching operation and degradation of resistive random access memory composed of tungsten oxide and copper investigated using in-situ TEM.

In-situ transmission electron microscopy (in-situ TEM) was performed to investigate the switching operation of a resistive random access memory (ReRAM) made of copper, tungsten oxide and titanium nitride (Cu/WOx/TiN). In the first Set (Forming) operation to initialize the device, precipitation appeared inside the WOx layer. It was presumed that a Cu conducting filament was formed, lowering the ...

In-situ Observation of the Growth of Tungsten Oxide Nansotructures

This paper describes a method for producing tungsten oxide nanostructues in an environmental scanning electron microscope. The growth is observed in real time and offers direct observation of the morphology of the tungsten oxide condensed onto the cooler part of a typical W Scanning Electron Microscope filament. We also find that the growth of nanostructures occurs on timescales much shorter th...
