In this study, dual S-scheme ZnIn2S4–Al2O3–ZnO (ZIS–Al–Zn) heterojunctions were produced by a facile, low cost, and rapid combustion technique. These accelerated the photocatalytic hydrogen production due to multi-channel-promoted separation of photocarriers. By optimizing content components, synthesized ZIS–Al–Zn composite with 20 wt% ZnIn2S4 30 Al2O3 in demonstrated highest rate 54.2 mmol g–1...

<p>In this paper, a simple color image compression system has been proposed using signal decomposition. Where, the RGB band is converted to less correlated YUV model and pixel value (magnitude) in each decomposed into 2-values; most least significant. According importance of significant (MSV) that influenced by any simply modification happened, an adaptive lossless bit plane (BP) slicing,...

Herein we demonstrate a novel plating bath, free from cyanide, to plate highly adherent nanocrystalline copper-silver (ncCuAg) coating on stainless-steel substrate and its application as an antimicrobial coating. The microstructures, such the grain size, texture, microstrain, crystalline preferential orientation of CuAg deposits, are systematically investigated by X-ray diffraction analysis. ra...

The electrolysis of water for substantial production hydrogen and oxygen with very high purity is considered as a potentially practical technology. In the present study, we have fabricated graphene-oxide hybrid zinc-selenide electrocatalyst characterized it using different techniques. XRD analysis confirms phase crystal structure electrocatalyst. Furthermore, elemental arrangement morphology we...

In this work, we propose a model with Lorentz symmetry violation which describes the electronic low energy limit of AA-bilayer graphene (BLG) system. The AA-type bilayer is known to preserve linear dispersion relation layer in limit. theoretical shows that BLG system, time-like vector can be associated separation and contributes eigenstates. Based on these properties, describe $(2+1)$-dimension...

The sustainable production of hydrogen and oxygen through the electrolysis water requires development an efficient electrocatalyst. In this work, we report electrocatalytic activity Pd nanoparticles dispersed on CeO2/N, S-rGO (where N, represents nitrogen sulfur-doped reduced graphene oxide). were synthesized by hydrothermal chemical reduction methods, respectively. Electrochemical measurements...

The ionic liquid (IL)-based electrolyte comprising 1.2 M lithium bis(fluorosulfonyl)imide (LiFSI) in N-Propyl-N-methylpyrrolidinium (PYR13FSI) (ILE) has been evaluated as a suitable system for the high-voltage cathode material LiNi0.5-xMn1.5+xO4 (LNMO) when cycled vs. graphite anodes. oxidative stability of ILE was by linear sweep voltammetry (LSV) and synthetic charge-discharge profile (SCPV) ...

Water pollution control and the development of clean technologies for water, air soil treatments comprise one most important challenges modern society. Ozone is known as a strong oxidizing agent that can be used water wastewater treatment. In this research, novel Ti/TiHx/SnO2-Sb2O5-NiO-CNT modified titanium electrode containing carbon nanotubes (CNT) was fabricated in-situ ozone generation. The...

This review summarizes some recent developments in the fabrication of modified sensors and biosensors using carbon-based materials. The great potential electrodes as sensing platforms is exciting due to their unique electrical chemical properties, high accessibility biocompatibility. Carbon-based materials are particularly interesting almost infinite possibility functionalization with a wide va...

Carbon supported PdCo catalysts in varying atomic ratios of Pd to Co, namely 1 : 1, 2 : 1 and 3 : 1, were prepared. The oxygen reduction reaction (ORR) was studied on commercial carbon-supported Pd and carbon-supported PdCo nanocatalysts in aqueous 0.1 M KOH solution with and without methanol. The structure, dispersion, electrochemical characterization and surface area of PdCo/C were determined...
