Antimicrobial Activity of ZnS and ZnO-TOP Nanoparticles Againts Pathogenic Bacteria.

This study aims to synthesize ZnS nanoparticles (NPs) and investigate their biocidal effects, along with those of ZnO-Trioctylphosphine (ZnO-TOP) NPs, on various pathogenic microbes. The NPs were synthesized via the polyol method using the forced hydrolysis of zinc acetate. They were characterized by XRD and TEM.

Efficient degradation of phenol using natural clay as heterogeneous Fenton-like catalyst.

A natural containing Fe-clay (NRC) was used for the Fenton-like oxidation of phenol. This new catalyst was very efficient in phenol elimination in aqueous medium under mild experimental conditions (20 °C, atmospheric pressure and low concentration of hydrogen peroxide). The influence of different parameters like calcination's temperature, particle size, initial phenol and H2O2 concentrations were examined considering both phenol conversion and total organic carbon (TOC) removal.
