Background and Aim: Lesions of the skin can impair its vital function to protect humans against external pathogens. Therefore, producing a suitable wound dressing to repair injuries is always one of the challenges of researchers. The present study aims to Synthesize a hydrogel film for wound dressing applications. Methods: In this research, a hydrogel film of polyvinyl alcohol / hyaluronic a...
Silver doped zinc oxide nanoparticles are synthesized by a solution combustion method. The samples characterized by a variety of spectroscopic and other techniques clearly reveal the presence of silver nanoparticles as well as silver clusters. The silver in the two forms was identified by careful deconvolution of X-ray photoelectron spectral results. Their formation was also confirmed by the pr...
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...
Background and Objectives: The advancement of nanotechnology has made it more important to study the destructive effects of nano-materials on organisms. Titanium dioxide and zinc oxide nanoparticles can enter the body in different ways and cause damage to the liver and other organs of the body. The purpose of this study was to evaluate the effects of zinc oxide and titanium dioxide nanoparticle...
In the title compound, [Zn(C(6)H(4)NO(3))(2)(H(2)O)(2)], the Zn atom is located on a centre of inversion and shows a distorted octa-hedral coordination geometry. Two aqua ligands occupy the axial positions and four O atoms of the two chelating picolinic acid N-oxide ligands are located in the equatorial plane. Inter-molecular hydrogen bonds between aqua ligands and organic ligands link mol-ecul...
Zinc-ion batteries (ZIB), with various manganese oxide-based cathodes, provide a promising solution for textile-based flexible energy storage devices. This paper demonstrates, the first time, aqueous ZIB manganese-based cathode fabricated in single woven polyester cotton textile. The textile was functionalized polymer membrane layer that fills gaps between yarns, enabling fine control over dept...
Zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in Hypericum perforatum cell suspension culture. High performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in H. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...
Studies were carried out to evaluate the initially preformed density and initial aspect ratio on the densification behavior of sintered Zinc and Zinc Oxide composite. The preform possessed 0.85 is the initial density. Aspect ratio for three different oxidizing temperatures (at 150°C, 200°C and 250°C) varied from 0.4 to 0.85. Properties of Zinc-Zinc Oxide composites with respect to linear strain...
a feasibility study on the possible growth of rod-shaped nano size zinc oxide particles on the surface of polyester fabric was investigated. the nanoparticles were produced using a hydrolysis method, with a zinc compound being utilized as the starter material. fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy/energy dispersive x-ray spectrometry (sem/eds) and x-ray d...
