Ethanol (C2H6O) sensitivity of zinc oxide (ZnO) thin film has been studied in present work. Semiconductor thin films of zinc oxide (ZnO) were deposited onto alkali-free glass substrates by the sol–gel method and dip-coating technique. The ZnO sol was synthesized by dissolving zinc acetate dehydrate in ethanol, and then adding Tetra ethanol-amine.  The as-coated films were preheated at 150 ºC fo...

PURPOSE OF REVIEW To evaluate clinical data indicating the benefits of oral zinc supplementation to prevent and/or treat diarrhea in children and extend these findings to adults. RECENT FINDINGS Zinc plays an important role in modulating host resistance to infectious agents and reducing the risk, severity, and duration of diarrheal diseases. Zinc is important in the developing world and in lo...

Zinc filter cakes (ZFCs) have economic values as secondary sources, but also are classified hazardous waste and negative effects on human health the environment because they contain several heavy metals. Especially extraction recovery of lead zinc metals from ZFCs will provide environmental benefits. Therefore, in this study, with a weak acid (ammonium acetate, AmAc) leaching was investigated, ...

Sodium silicate binders are a promising binder base for obtaining effective granular thermal insulation materials. Increasing water resistance, first of all, will expand the scope their application in construction. At same time, features modification sodium by compounds polyvalent metals have not been fully studied, interaction with which leads to formation hardly soluble silicates. The purpose...

Most countries are facing problems of environmental pollution due to toxic organic pollutants being discharged into the environment from various man-made sources. Heterogeneous photocatalysis is a possible solution for mentioned problem, and it has been widely applied removal aqueous solutions, thanks its high efficiency friendliness. Among commonly used metal oxides, ZnO attracted researchers’...

The goal of the current research was to synthesis zinc oxide nano-particles (ZnONPs) via simple, cheap and eco-friendly method which include reduction acetate dehydrate ZnONPs by using black currant aqueous extract (BC) as a reducing-agent. characterization stability, size, morphology, present functional groups on surface synthesized ZnOBCNPs were achieved SEM, X–ray diffraction, FTIR spectrosc...

Zinc(II) complexes with dangling functional organic groups were synthesized by reaction of zinc acetate with a series of bifunctional p-substituted benzene derivatives (a combination of carboxylate, oximate, amino, β-ketoimine, and salicylaldime groups). Selective coordination to carboxylate groups was observed when the second functional group was an oxime or β-ketoimine group. When the second ...

Low-temperature aqueous chemical growth methods have shown great potential in the synthesis of ZnO nanostructures. Hexamethylenetetramine (HMTA) is the most common chemical substance used in the hydrothermal synthesis. In this study zinc oxide nanoparticles were prepared via hydrothermal growth using zinc acetate dihydrate and sodium hydroxide, as precursors instead of HMTA, as it is commercial...

The mononuclear zinc title complex, [Zn(C(20)H(22)N(2)O(4))(H(2)O)], was obtained by the reaction of 3-eth-oxy-salicyl-aldehyde, ethane-1,2-diamine, and zinc acetate in methanol. The Zn atom is five-coordinated by two phenolate O and two imine N atoms of the tetradentate Schiff base ligand and by one water O atom, forming a square-pyramidal geometry. In the crystal, pairs of mol-ecules are link...
