Nanoscale materials can have cytotoxic effects. Here we present the first combined empirical and theoretical investigation of the influence of electrostatic attraction on nanoparticle cytotoxicity. Modeling electrostatic interactions between cells and 13 nm spheres of zinc oxide nanoparticles provided insight into empirically determined variations of the minimum inhibitory concentrations betwee...

The effect of topical application of copper and zinc nanoparticle suspensions on the dynamics of bacterial contamination of the experimental purulent wound was studied. A model of purulent wound infected with polyantibiotic-resistant clinical strains of Staphylococcus aureus isolated from orthopedic trauma patients was obtained in 30 white male rats. The use of copper nanoparticle suspension en...

Ferrites with spinel structure are the most widespread materials in radio engineering, electronics and communication industry, microwave devices and computer facilities. The change of synthesis temperature of ferrites results in cation redistribution of iron, which updates crystal properties, as macroscopic magnetic properties of ferrites. Among this extensive class of compounds nickel and copp...

RF thermal plasma synthesis of zinc-ferrite nanopowders has been studied from metallurgical wastes of high iron oxide and zinc oxide and/or hydroxide content. XRD measurements of the products revealed that an extensive spinel formation took place on RF plasma treatment. However, instead of expectable ZnFe2O4, formation of zinc ferrous ferrites (Zn0,7Fe2,3O4 and Zn0,4Fe2,6O4) was concluded from ...

Spinel zinc ferrite nanomaterials with exceptional physiochemical properties are potential candidates for various applications in the energy and environmental fields. Their can be tailored using several methods to widen their applications. The chemical combustion approach was followed prepare spinel nanomaterials, which were then subjected thermal treatment at a fixed temperature. Thermal heat ...

Phytotoxicity is an important consideration to understand the potential environmental impacts of manufactured nanomaterials. Here, we report on the effects of four metal oxide nanoparticles, aluminum oxide (nAl(2)O(3)), silicon dioxide (nSiO(2)), magnetite (nFe(3)O(4)), and zinc oxide (nZnO), on the development of Arabidopsis thaliana (Mouse-ear cress). Three toxicity indicators (seed germinati...

The soft chemical method was adopted for the synthesis of cobalt substituted nickel-zinc and zinc-nickel ferrites (Ni0.95-xZn0.05CoxFe2O4 Zn0.95-xNi0.05CoxFe2O4 x= 0.01, 0.02, 0.03, 0.04, 0.05, 0.06. We have recently studied structural, morphological, magnetic properties, initial permeability, dielectric constant samples. They are found with cubic ferromagnetic spinel structure along morphology...

in the present study, comparison of  photocatalytic activity of nanostructures semiconductor zinc oxide (zno) was prepared using the different methods on the degradation of organic dye such as methylene blue that was investigated. previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organ...
