Antimicrobial Effect of Transition Metal Oxide Nanoparticles

Reducing zinc oxide in rubber industry use through the development of mixed metal oxide nanoparticles

Despite its superior characteristics, there is an increased concern about the environmental effects that zinc oxide causes and over the years lower levels of zinc have been tried in order to decrease its impact and to minimise the production costs. Different approaches have been considered for reducing zinc levels. Between all the alternatives proposed, the use of nano–sized ZnO particles with ...

Metal Oxide Nanoparticles

This chapter covers the fundamental science, synthesis, characterization, physicochemical properties and applications of oxide nanomaterials. Explains fundamental aspects that determine the growth and behavior of these systems, briefly examines synthetic procedures using bottom-up and top-down fabrication technologies, discusses the sophisticated experimental techniques and state of the art the...

Toxicity of 100 nm zinc oxide nanoparticles: a report of 90-day repeated oral administration in Sprague Dawley rats

Nanoparticles (NPs) are used commercially in health and fitness fields, but information about the toxicity and mechanisms underlying the toxic effects of NPs is still very limited. The aim of this study is to investigate the toxic effect(s) of 100 nm negatively (ZnO(AE100[-])) or positively (ZnO(AE100[+])) charged zinc oxide (ZnO) NPs administered by gavage in Sprague Dawley rats, to establish ...

Zinc Oxide Nanoparticles Prepared by the Reaction of Zinc Metal with Ethanol

Zinc oxide nanoparticles have been prepared by a very simple reaction of zinc metal with ethanol at 200 oC. The diameters of the nanoparticles range from 50–200 nm with an average diameter of 100nm. The reaction involves the cleavage of C-O bond of the alcohol, which occurs readily on zinc metal surface. Addition of ethylenediamine to the reaction yields nanorods, the amine acting as a shape co...
