background: the current study aimed to determine the effect and properties of surface-modified copper doped cu:zno nps on killing curves of bacterial pathogens. m ethods:   preparation  of   in  situ   surface-modified  copper  doped  zno nanoparticles (cu:zno nps) was done according to standard procedure.assay for antimicrobial activity of cu:zno nps against bacterial pathogens was carried out...

The problem of sulfur content in heavy oil is a challenge for researchers to meet the needs environmentally friendly fuels. catalyst preparation plays an important role desulfurization process. synthesis ZnO-activated carbon as and its activity oxidative (ODS) reaction has been successfully carried out. In this work, ZnO activated (AC) were blended by solid-solid reaction. ZnO, AC, ZnO-AC then ...

The binary MgO–ZnO and CaO–ZnO systems the ternary CaO–MgO–ZnO system were thermodynamically optimized with phase equilibria studies in this study. Bragg-Williams random mixing model was used for solid solutions, while Modified Quasichemical Model liquid solution. thermodynamic optimization conducted using Factsage 8.1 thermochemical software. diagrams fit well experimental results. performed a...

Various forms of zinc oxide (ZnO) are frequently used in the design optical and electrochemical sensors. However, properties ZnO should be properly adjusted depending on application area. Therefore, this work, we have investigated changing/tuning by depositing a layer polydopamine (PDA) its surface. In order to perform investigation, surface fluorine-doped tin (FTO) was modified with nanorods P...

Tremendous effort has been put into developing viable lithium sulfur batteries, due to their high specific energy and relatively low cost. Despite recent progress in addressing the various problems of sulfur cathodes, lithium sulfur batteries still exhibit significant capacity decay over cycling. Herein, we identify a new capacity fading mechanism of the sulfur cathodes, relating to Li(x)S deta...

Theoretical predictions using a modified radical species ternary diagram for C–H–O system indicate that addition of sulfur expands the C–H–O gas phase compositional window for diamond deposition. Sulfur addition to no-growth domain increases the carbon super-saturation by binding the oxygen and the addition of sulfur to the non-diamond domain reduces the heavy carbon super-saturation by decreas...

ZnO nanoparticles were prepared by hydrothermal method. The modified Hummer process was then used to prepare go. ZnO-GO com posites mixed produce different ratios of ZnO-GO, characteris ed and their photocatalytic properties investigated using rhodamine B as the target degradation species. results showed that r ates 41.96% 84.42% for nano-ZnO 7% composites, respectively, when illuminated with x...

Abstract In this study, a novel adsorbent (SRM-ZnO) was prepared using zinc oxide supported on red mud in seawater medium and used for the adsorption of methyl orange (MO). It is expected to solve recycling prepare an economical with high efficiency adsorb dye wastewater. Material composition morphology analyses showed that hydrotalcite compounds were attached surface SRM-ZnO. The can increase ...
