Thin films of tungsten trioxide were deposited on quartz substrates by RF magnetron sputtering. Different annealing temperatures in the range from 423 to 973 K were used under ambient atmosphere. The influence of the annealing temperature on the structure and optical properties of the resulting WO3 thin films were studied. The surface morphology of the films is composed of grains with an averag...

Efficient evolution of hydrogen through electrocatalysis at low overpotentials holds tremendous promise for clean energy. Hydrogen evolution can be easily achieved by electrolysis at large potentials that can be lowered with expensive platinum-based catalysts. Replacement of Pt with inexpensive, earth-abundant electrocatalysts would be significantly beneficial for clean and efficient hydrogen e...

In this work, we demonstrate a novel carrier transporting combination made of tungsten trioxide (WO3) nanomaterials and Cs2CO3/PCBM buffer bilayer for the fabrication of perovskite solar cells (PSCs). Two different types of WO3, including nanoparticles and nanorods, were prepared by sol-gel process and hydrothermal method, respectively. Cs2CO3/PCBM buffer bilayer was inserted between WO3 and pe...

Abstract 2D materials‐based device performance is significantly affected by film non‐uniformity, especially for large area devices. Here, it investigates the dependence of MoS 2 phototransistor on morphology through correlative mapping. Monolayer films are quazi‐epitaxially synthesized C‐plane sapphire (Al O 3 ) substrates chemical vapor deposition, and growth time molybdenum trioxide MoO precu...

Nowadays bimetallic nanoparticles (NPs) have emerged as key materials for important modern applications in nanoplasmonics, catalysis, biodiagnostics, and nanomagnetics. Consequently the control of bimetallic structural motifs with specific shapes provides increasing functionality and selectivity for related applications. However, producing bimetallic NPs with well controlled structural motifs s...

Abstract In this study, a group of molybdenum boro-tellurite glass samples and their mechanical parameters nuclear radiation shielding competencies were investigated. The amorphous structures glasses confirmed by XRD patterns. Synergistic positive effect MoO 3 reinforcement on gamma ray attenuation properties was For aim, in the energy range 0.015–15 MeV, mass coefficients (MAC) had been comput...
