Background: The purpose of this study was to investigate the effect of copper and aluminum-zinc oxide nanoparticles and their synergistic effects with conventional biocides against Bacillus cereus. Methods: Synthesis of copper-zinc oxide, aluminum-zinc oxide nanoparticles performed via co- precipitation method and nanoparticle properties were investigated using FTIR, XRD and TEM. The antimicro...
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...
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...
Materials and methods: Performance and nutrient digestibility were determined for pigs consuming either water treated by reverse osmosis (RO; 219 mg total dissolved solutes (TDS) per L, 29 mg sulfates per L) or untreated ground water (3078 mg TDS per L, 1650 mg sulfates per L). In each of two experiments, approximately 240 pigs (20 ± 3 days of age, 5.9 ± 1.0 kg) received either RO-treated or un...
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...
ICP-MS analysis of Streptococcus pneumoniae reveals a high cell-associated Mn(II) concentration that is comparable to that of Zn(II). Stressing these cells with 100–200 μM Zn(II) leads to a slow-growth phenotype and a total Mn(II) concentration that is reduced, with no decrease of other metal ions. Supplementation of the growth media with as little as 10 μM Mn(II) fully restores the growth defe...
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...
