Here, we report on the synthesis of tungsten diselenide (WSe2) nanosheets using an atmospheric pressure chemical vapor deposition technique via rapid selenization thin films. The morphology and structure, as well optical properties, so-produced material have been studied electron microscopies, X-ray photoelectron spectroscopy, photoluminescence, UV–visible Raman spectroscopies, diffraction. These studies confirmed high crystallinity, quality, purity, orientation WSe2 nanosheets, in addition...
Herein, we present, for the first time, a chemoresistive-type gas sensor composed of two-dimensional WSe2, fabricated by simple selenization tungsten trioxide (WO3) nanowires at atmospheric pressure. The morphological, structural, and chemical composition investigation shows growth vertically oriented three-dimensional (3D) assemblies edge-enriched WSe2 nanoplatelets arrayed in nanoflower shape. sensing properties flowered (2H-WSe2) are investigated thoroughly toward specific gases (NH3 NO2)...
2D materials, given their form-factor, high surface-to-volume ratio, and chemical functionality have immense use in sensor design. Engineering heterostructures can result robust combinations of desirable properties but design methodologies require careful considerations about material orientation to maximize response. This study introduces a approach that combines the excellent electrical transport transduction graphite film with reactivity derived from edge sites semiconducting molybdenum...
The present work reports on the low-pressure, radio-frequency, plasma-driven synthesis of ε-Fe3N-type nanoparticles homogeneously deposited a high-surface-area porous carbon support, with tunable magnetic properties, directly depending plasma treatment conditions. Iron are formed from degradation solid organometallic precursor mixed xerogel in nitrogen-containing (argon/ammonia) discharge. Variation working pressure during affects residence time reactive species, which determines crystalline...
Laminated metal dichalcogenides are candidates for different potential applications ranging from catalysis to nanoelectronics. However, efforts still needed optimize synthesis methods aiming control the number of layers, morphology, and crystallinity, parameters that govern properties synthesized materials. Another important parameter is thickness length samples with possibility large-scale growth target homogeneous Here, we report a chemical vapor deposition method at atmospheric pressure...
Abstract In this paper, a previously established 3D multi-scale simulation chain of plasma deposition process, based on combination direct Monte Carlo (gas phase) algorithm and kinetic (kMC) (film growth) code, is improved by the addition particle-in-cell collision in order to take into account clarify role charged particles. The code also extended with binary approximation handle This modelling strategy successfully applied growth TiO 2 thin films means reactive magnetron sputtering....
The aim of this work is to investigate the consequences lattice distortion on vibrational features rare-earth perovskites. To end, a series REMO3 compounds has been synthesized with different rare earths (RE = La, Pr, Nd, Sm) and transition metals (M Fe, Co) evaluate their respective role distortion. Thin films these materials have deposited by magnetron cosputtering in reactive mode followed annealing air same experimental conditions. Characterizations including energy-dispersive X-ray...
In this study, the tuning of KOH electrolyte composition is proposed as a strategy to drastically limit capacitance fade vanadium nitride (VN) electrode. We demonstrate that use V 5+ (as VO 4 3− vanadates anions) containing enhances cycling stability VN thin film electrode: loss 59% observed for electrode tested in over 3000 consecutive cycles. After addition electrolyte, decreased 23%. Furthermore, presence species solution leads enhancement from 379 mF cm −2 ions free up 577 at 5 mV s −1...
Nanocatalyst materials based on metal nanoparticles (NPs) deposited mesoporous carbon substrates are widely used in catalysis and energy storage; however, conventional wet-chemical deposition methods the reduction of salts not always best choice when looking for a process ensuring easy scalability low environmental impact. Moreover, additional surface functionalization steps, such as addition nitrogen- or oxygen-containing groups, more explored to increase activity chemical stability...
