a novel zinc oxide - agar nanocomposite was successfully synthesized using zinc chloride as a precursor. the nanocomposite was prepared using a domestic microwave oven. the prepared nanocomposites have been characterized by fourier transform infrared (ftir) spectroscopy, x-ray diffraction (xrd) analysis, scanning electron microscopy (sem) and uv- visible spectroscopy. the crystalline properties...

zno nanocrystalline thin films were synthesized using cathodic reduction of zn foil in aqueous electrolyte containing  zncl2 and h2o2, followed by annealing at 400 oc in the air. the x-ray diffraction pattern exhibited a set of well-defined diffraction peaks corresponding to the zno wurtzite phase. scanning electron microscope and transmission electron microscope images clearly revealed formati...

BACKGROUND Antibiotic resistance is a global issue that threatens public health. The excessive use of antibiotics contributes to this problem as the genes of antibiotic resistance can be transferred between the bacteria in humans, animals and aquatic organisms. Metallic nanoparticles could serve as future substitutes for some conventional antibiotics because of their antimicrobial activity. The...

Ab initio calculations at the density functional theory (DFT) and the second-order Møller−Plessetperturbation theory levels with 6-31+G(d), 6-31G(d) basis sets for non-metal atoms and LANL2DZfor metal have been performed for the adsorption of dimethyl methylphosphonate (DMMP) on ZnOby Gaussisn 98 program. The calculated rotational constants by B3LYP/6-31G(d) are in moreagreement with the experi...

Objective(s): Nanoparticles (NPs) are particles with the size range approximately from 1 to 100 nanometers that are made in different shapes. Nanotechnology is an emerging technology that expected to open some new opportunities in order to destroy and control of microorganisms using of materials and systems at the scale of the atom. Echinococcus granulosus is the agent of cystic echinococcosis ...

The consequences of zinc oxide (ZnO), Aluminum oxide ( 3 2O Al ) and Titanium oxide (TiO2) on tree growth have been comprehensively investigated in this paper. Zinc oxide (ZnO), II-VI compound semiconductor, is used in varistors in power insulation life. Due to its excellent electrical properties such as nonlinearity of current-voltage (I-V) characteristics, high fast-transient response and hig...
