ABSTRACT With the increasing clinical use of titanium dioxide (TiO 2 ) nanoparticles, a better understanding their safety in blood stream is required. The present study evaluates toxic effect commercially available TiO nanoparticles (~100 nm) using battery cytotoxic, genotoxic, hemolytic and morphological parameters. cytotoxic effects human lymphocyte cells were studied with respect to membrane damage, mitochondrial function, metabolic activity lysosomal stability. Genotoxicity was...
Agricultural biotechnology has become familiar with nanomaterials' properties and potential use. The present experiment was conducted to examine the effect of 8.1±1.6 nm sized silver nanoparticles (AgNPs) on growth performance yield quality pea (Pisum sativum) as well Arbuscular Mycorrhizal Fungi (AMF) Rhizobium population in soil. Pea seeds were separately treated 3 h 1 mM, 2.5 5 mM AgNPs aqueous solution, after 2 weeks their seed germination, leaf number, shoot, root length, shoot dry...
Biosynthesis of gold nanoparticles (AuNPs) was obtained by a simple chemical reduction method using plant-derived aglycone flavonoid, quercetin, as reducing agent. The aqueous chloroauric acid when exposed to quercetin reduced and converted AuNPs in the size range from 20 45 nm. were characterised UV–visual spectroscopy, transmission electron microscopy, atomic force microscopy dynamic light scattering method. These quercetin-mediated have shown excellent stability for more than 30 days at...
Purpose: The present work was intended to evaluate the radioprotective effect of quercetin against gamma radiation-induced oxidative stress on red blood cells (RBC).Materials and methods: Swiss albino male mice were treated with (100 mg/kg body wt) for three consecutive days prior 5 Gy 60Co-gamma irradiation. RBC isolated estimate level intracellular reactive oxygen species (ROS), membrane lipid peroxidation (LPO), reduced glutathione (GSH), mean corpuscular hemoglobin concentration (MCHC),...
Sustainable Development (SD) is the universal essentiality of present times, and universities have a critical role in implementing this initiative through their functioning, policies practices. To integrate SD goals, should global outlook that still locally rooted its strategies. In last decade, various theories recommendations been proposed adopted globally for integrating sustainability higher education systems. India, environmental has mandated at all formal levels system. Still, there...
The present study reports an eco-friendly approach to synthesize gold nanoparticles by simple reduction of chloroauric acid using Moringa oleifera leaf extract as reducing agent. Aqueous when exposed was reduced and converted in the size range between 20–60 nm at normal room temperature. Various phytochemicals act agents stabilizers. Gold were characterized UV-Vis spectroscopy, atomic force microscopy dynamic light scattering method. Leaf mediated exhibited excellent stability for more than...
The performance of fiber-reinforced composites significantly relies on the microstructure and properties fiber–matrix interface. Escalating aspect ratio fiber surface by coating with nanoparticles is a proven technique for improving fiber/matrix adhesion. Subsequently, improved adhesion between epoxy fiber, which ascribed due to interfacial friction, chemical bonding, resin toughening would enhance strength such laminated composites. Here, graphite were oxidized, these charged particles...
India, as a developing nation, is consistently progressing in the education field. While Indian higher has expanded tremendously terms of enrolment, country failed to produce an adequate number world-class universities. Researchers have analysed challenges like demand-supply gap, lack quality research and innovation, inadequate infrastructure, shortage faculty, etc. Worldwide policies been transformed by various internationalisation processes that operate constant flux globalisation. Given...
AbstractChromium is a metal which has both biological and environmental interest. It occurs in nature mostly two stable oxidation states Cr(III) Cr(VI). non-toxic plays significant role carbohydrate fat metabolism, whereas Cr(VI) highly toxic (MAC value 50 μg L−1 only). Being major industrial pollutant, it hazardous effect on man, animal plant life. In the present investigation, an attempt been made to develop selective sensitive method for spectrophotometric determination of Cr(III), total...
Corrosion is a costly problem all over the world. Current approaches to controlling corrosion have some paucity of efficiency, which triggers search for novel materials that are green and cheap made from renewable resources. In this study, an attempt was prepare Acacia auriculiformis-seed-oil (ASO)-based fatty amide through simple reaction route involving aminolysis ASO acid diethylenetriamine. Fourier transform infrared spectroscopy hydrogen-1 ( 1 H) nuclear magnetic resonance were used...
