In this work, growth and assembly of the micro polyhedral zinc oxide was performed using airbubble assisted Triton X100, as a templating agent. In absence of air bubbling in the reactionsystem the nano plate zinc oxide was synthesized. The prepared samples were characterized by Xraydiffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV-Visspectrop...

Zinc (Zn) deficiency in major food crops has been considered as an important factor affecting the crop production and subsequently the human health. Rice (Oryza sativa) is sensitive to Zn deficiency and thereby causes malnutrition to most of the rice-eating Asian populations. Application of zinc solubilizing bacteria (ZSB) could be a sustainable agronomic approach to increase the soil available...

Nanostructured zinc oxide (ZnO) was successfully synthesized by precipitation method using the extract of Cylea barbata Miers (CBM) leaves as a soft template after 3 h of calcinations in furnace at 500oC in the open air. Characterization results showed that the nanostructured ZnO had hexagonal wurtzite structure with space group P63mc and nano-scale particle diameter. It was suggested that the ...

Objective(s): Since microbial contamination can reduce the shelf life of the foodstuff and there is a potential for the growth of some pathogen microorganisms, films containing antimicrobial agents were produced, which are also biodegradable. In this study, the effect of 1, 3 and 5% nano-zinc oxide on antimicrobial properties and permeability of poly lactic acid film was invest...

introduction: the aim of this study was to evaluate the cytotoxicity of a new nano zinc-oxide eugenol (nzoe) sealer in comparison with ah-26 and pulpdent root canal sealers. methods and materials: the l929 mouse fibroblast cells were cultivated and incubated for 24, 48 or 72 h with different dilutions (1/1, 1/2, 1/4, 1/8, 1/16 and 1/32) of culture media previously exposed to either of the test ...

metal-organic frameworks (mofs) represent a new class of highly porous materials. on this regard,  two nano porous metal-organic frameworks of [zn2(1,4-bdc)2(h2o)2∙(dmf)2]n (1) and [zn2(1,4-bdc)2(dabco)]·4dmf·1⁄2h2o (2), (1,4-bdc = benzene-1,4-dicarboxylate, dabco = 1,4-diazabicyclo[2.2.2]octane and dmf = n,n-dimethylformamide) were synthesized and characterized. they were used for preparation ...

the photocatalytic degradation of betamethasone sodium phosphate was investigated in aqueoussuspensions of zinc oxide nanoparticular with diameter size 20 nm under a variety of conditions.different parameters such as irradiation time, the amount catalyst (0.12-0.8 g lh), initialconcentration of drug (10-50 mgljand initial ph values (ranging from 3 to ii) were investigatedin the presence of vari...

Objective(s): Nowadays, tendency to use green materials can reduce environmental pollution and plastic waste. Poly (lactic Acid) PLA is one of the natural biodegradable polymers mainly used in the production of bioplastics for packaging which is made of non-toxic compounds and is easily biodegradable. In this research, the effect of 1, 3 and 5% nanocomposite zinc oxide on the morphological, mec...

The hexagonal zinc oxide coated nickel (Ni/ZnO) nanostructure photocatalyst has successfully been prepared by the reduction of nickel chloride hexahydrate using hydrazine hydrate through the solvothermal process at 140 °C followed by surface modification of the product by the reflux method at 110 °C for 1 h. The X-ray diffraction (XRD) pattern showed that the 'as prepared' sample consists of fa...
