Zinc oxide nano-particles with the average diameter of about 25 nm were modified with different mole ratios of trimetoxyvinyl silane (TMVS) and oleic acid, as coupling agents, in order to modify their surface properties and render them more hydrophobic. Then, dispersibility of the surface modified nano-particles was examined in some monomers with different levels of hydrophobicity, including me...

In the present work, we report the synthesis of binary nano metal oxides such as Zinc /Copper Oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. The synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦C. X...

Nanomaterials are particles with 10 to100 nanometer size. They can easily be transportedthrough the skin, lung alveoli, and placenta. Materials in nano scales show different propertiescompared with the same materials in macro or larger scale. It is found that zinc element is anessential metal for normal physiological functions. However increase or decrease of this elementduring pregnancy, for e...

Antibiotic resistance has impelled the research for new agents that can inhibit bacterial growth without showing cytotoxic effects on humans and other species. We describe the synthesis and physicochemical characterization of nanostructured ZnMgO whose antibacterial activity was compared to its pure nano-ZnO and nano-MgO counterparts. Among the three oxides, ZnO nanocrystals-with the length of ...

The aqueous extract of Ocimum basilicum leaves and zinc salts (zinc sulphate) was used as precursors in this investigation to create oxide nanoparticles. ultraviolet-visible spectroscopy, scanning electron microscopy, Dynamic light scattering (DLS) were characterize the produced (SEM), Energy-dispersive X-ray analysis (EDX), Because UV-Vis spectra exhibit absorption peaks 350 nm range. DLS prov...

Since the prohibition of tributyltin (TBT)-based antifouling paints in 2008, the development of environmentally compatible and commercially realizable alternatives is a crucial issue. Cost effective fabrication of antifouling paints with desired physical and biocompatible features is simultaneously required and recent developments in the direction of inorganic nanomaterials could play a major r...
