BACKGROUND Galvanization is the process of coating steel or cast iron pieces with a thin layer of zinc allowing protection against corrosion. One of the important hazards in this industry is exposure to zinc compounds specially zinc oxide fumes and dusts. In this study, we evaluated chronic effects of zinc oxide on the respiratory tract of galvanizers. METHODS Overall, 188 workers were select...

Nanostructured zinc oxide is intensively studied semiconductor showing photocatalytical activity. There are several precursors which can be used for the preparation of nanostructured zinc oxide like zinc acetate, zinc sulphate and many others. Zinc chloride is another compound which can serve as a zinc source for zinc oxide preparation. Nowadays the environmental aspects connected to applicatio...

objective: the aim of this study was to evaluate the effect of zinc and magnesium supplementation on glycemic control and serum insulin in type 2 diabetic patients. materials and methods: in this randomized clinical trial 70 diabetic patients who referred to yazd diabetes center were selected. subjects received 500 mg/day magnesium oxide or 100 mg/day zinc sulfate randomly for 8 weeks. at the s...

The complex [Zn2(btca)(H2O)4] was synthesized with 1,2,4,5-benzenetetracarboxylic acid (H4btca) and zinc acetate as materials via a room-temperature solid state reaction. The composition and structure of the complex were characterized by elemental analyses (EA), Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), and thermogravimetric (TG) analysis. The index results...

Ultra-violet protection and self-cleaning action of nano zinc oxide (ZnO) and titanium di-oxide (TiO2) with acrylic binder has been assessed on the cotton fabric using pad-dry-cure method. Different precursors, such as zinc acetate and titanium tetrachloride have been used to synthesize nanoparticles. Zinc acetate is synthesized into nanoparticle by wet chemical technique and titanium tetrachlo...

Phosphate-based glasses have been examined in many studies as a potential biomaterial for bone repair because of its degradation properties, which can be controlled and allow the release of various elements to promote osteogenic tissue growth. However most of these experiments studied either tertiary or quaternary glass systems. This study investigated a qinternary system that included titanium...

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...

We present an all-oxide solar cell fabricated from vertically oriented zinc oxide nanowires and cuprous oxide nanoparticles. Our solar cell consists of vertically oriented n-type zinc oxide nanowires, surrounded by a film constructed from p-type cuprous oxide nanoparticles. Our solution-based synthesis of inexpensive and environmentally benign oxide materials in a solar cell would allow for the...
