In this study, the extract of coffee powder for green synthesis of zinc oxide nanoparticles has been used because it is compatibility with the environment and it does not produce any toxic substances in the reaction. Then, the interaction of zinc oxide nanoparticles with calf thymus DNA with various spectroscopic methods such as UV-Visible, fluorescence and circular dichroism (CD) techniques wa...
In this study, zinc oxide (ZnO) as well ZnO/GO (zinc oxide/graphene oxide) were successfully synthesized. The Carica papaya leaf extract was used to synthesize ZnO and oil palm empty fruit bunch biomass obtain graphene, which further graphene oxide. samples characterized through a variety of analytical methods such scanning electron microscopy, transmission X-ray diffraction analysis, Fourier t...
We report the nanostructures and gas-sensing properties of Zinc oxide nanosheets prepared by hydrothermal method. In particular, needlelike Zinc oxide was also prepared for comparison. The morphology and structural properties were investigated using X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). Subsequent gas-sensing measurement between ...
Background & Aims: Phenylhydrazine cause adverse effect on testis tissue and hormone levels. This study was conducted to evaluate the effects of nano zinc oxide on the Testis Tissue and sex hormone levels after Phenylhydrazine-induced hypoxia in male mice. Materials & Methods: In order to perform the study 72 adult male mice with the capability of fertilizing with the age range of 6-8weeks ran...
An experiment was conducted to estimate the bioavailability and evaluation chemical properties of different zinc sources such as zinc sulfate, zinc oxide A, zinc oxide B and Bioplex Zn in broiler chickens fed by semi-puirfeid diets., At first, for chemical and solubility evaluation of different zinc sources in different solvents based on standards methods, 3 samples each containing 1 and 0...
In recent years, research into materials with high dielectric constants, including doped titanium oxide, has increased because of the potential for modern microelectronics applications and high-density energy storage. The aim of this study was to investigate the effects of zinc oxide as an acceptor additive on the dielectric properties and microstructure of titanium oxide ceramics. The amount o...
Jasada bhasma (zinc ash) is an extensively used Ayurvedic medicine for treating diabetes mellitus. The present communication presents yet unavailable comprehensive scientific data on its physico-chemical nature vis-a-vis anti-diabetic activity and toxicity profile.Zinc ash prepared by traditional method was found to consist of 200-500 nm sized particles, predominantly zinc oxide with hexagonal ...
in this research zinc oxide (zno) nano-crystalline powders were prepared by sol-gel method using zinc acetate. the zno nanoparticles were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), ultraviolet-visible (uv-vis), fourier transform infra-red (ft-ir) and energy dispersive x-ray (edx) spectroscopy. the structure of nanoparticles was studied using xrd pattern. the c...
