In this study, Zinc Oxide nanoparticles (ZnONPs) were synthesized by chemical method and their antibacterial efficiency against a clinical isolate of Staphylococcus aureus was studied. The Zinc Oxide nanoparticles have shown a commendable inhibition effect on the growth of most notorious bacterial pathogen S.aureus. The nanoparticles size and shapes were characterized by trans...

Leaching mechanism of zinc oxide is important not only to understand zinc smelting process but also to develop of new zinc recycling process. Recycling of zinc is mainly done by treatment of electric arc furnace dust (EAF dust). In Japan pyro metallurgical process is enhanced for EAF dust treatment, however only zinc oxide can be recovered by pyro metallurgical process. Hydro metallurgical proc...

The Cover Feature illustrates that asphaltene, an oil sands by-product typically used for road making, can be as a conductive substrate effective Mn−Co based bifunctional electrocatalysts in zinc-air batteries. A by-product, commonly associated with the negative environmental impact of fossil fuels, has been repurposed part solution to our dependence on these fuels. More information found Resea...

Optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of ZnO semiconductor. In optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the Bruggeman homogenization formalism. ZnO nano rods (ZONRs) as a nucleus layer were fabricated on the Indium Tin Oxide (ITO) by chronoamperometry (CA) in a...

The sluggish kinetics of electrocatalysts in the alkaline hydrogen evolution reaction (HER) is a critical challenge to attain efficient progress water electrolysis for carbon-neutral production. Here, we present high-performance and durable heterostructure NiMo/CoMoO4 HER constructed via two-pot situ growth strategy on nickel foam (NF). density active sites surface area hybrid catalyst augmente...

the antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. the useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. the aim of this study was to evaluate antibacterial activity properties of silver doped zinc...

Objective(s): Since microbial contamination can reduce the shelf life of the foodstuff and there is a potential for the growth of some pathogen microorganisms, films containing antimicrobial agents were produced, which are also biodegradable. In this study, the effect of 1, 3 and 5% nano-zinc oxide on antimicrobial properties and permeability of poly lactic acid film was invest...

Platinum (Pt) was selectively photodeposited onto zinc rhodium oxide (ZnRh2O4) to serve as a hydrogen (H2)-evolution photocatalyst in silver (Ag)-inserted ZnRh2O4 and bismuth vanadium (Bi4V2O11) solid-state (ZnRh2O4/Ag/Bi4V2O11). The amount of deposited Pt controlled by the photodeposition time generate Pt-loaded ZnRh2O4/Ag/Bi4V2O11 (Pt/ZnRh2O4/Ag/Bi4V2O11) containing up 0.17 wt % cocatalyst. p...

The layered ternary chalcogenide, palladium phosphorous sulphide (PdPS), and its composite with reduced graphene oxide are shown to be efficient hydrogen evolution electrocatalysts. The Tafel slope and the exchange current density values associated with hydrogen evolution reaction are determined to be 46 mV dec(-1) and 1.4 × 10(-4) A cm(-2) respectively.
