In this paper, we address the synthesis of nano-coalesced microstructured zinc oxide thin films via a simple thermal evaporation process. The role of synthesis temperature on the structural, morphological, and optical properties of the prepared zinc oxide samples was deeply investigated. The obtained photoluminescence and X-ray photoelectron spectroscopy outcomes will be used to discuss the sur...

the use of an inorganic phase in water-in-oil (w/o) microemulsion   has   received considerable attention recently for preparing metal oxide   nanoparticles. this is a technique, which allows preparation of ultrafine   metal oxide nanoparticles within the size range 40 to 80 nm. preparation of   nano zno and cr 2 o 3 studied, investigated in the inverse   microemulsion system. therefore the nuc...

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...

OBJECTIVES Recurrent caries was partly ascribed to lack of antibacterial properties in composite resin. Silver and zinc nanoparticles are considered to be broad-spectrum antibacterial agents. The aim of the present study was to evaluate the antibacterial properties of composite resins containing 1% silver and zinc-oxide nanoparticles on Streptococcus mutans and Lactobacillus. MATERIALS AND ME...

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...

Zinc oxide nanostructures are deposited on glass substrates in the presenceof oxygen reactive gas at room temperature using the radio frequency magnetronsputtering technique. In this research, the effects of zinc oxide sputtering pressure on thenanostructure properties of the deposited layer are investigated. The deposition pressurevaries from 7.5 to 20.5 mTorr. AFM resu...

Silver doped zinc oxide nanoparticles are synthesized by a solution combustion method. The samples characterized by a variety of spectroscopic and other techniques clearly reveal the presence of silver nanoparticles as well as silver clusters. The silver in the two forms was identified by careful deconvolution of X-ray photoelectron spectral results. Their formation was also confirmed by the pr...
