Immobilization of diastase α-amylase on nano zinc oxide

Food Chemistry, 2016
Diastase α-amylase extracted from malt, catalyses break down of starch into maltose. It is commonly used in food and fermentation industry. In the present study nano zinc oxide is used as support for this starch hydrolyzing enzyme. IR study revealed that the enzyme got adsorbed via electrostatic interaction with the functional groups on the support ...

Preparation and Use of Nano Zinc Oxide in Neoprene Rubber

International Journal of Polymeric Materials and Polymeric Biomaterials, 2008
Zinc oxide (ZnO) of nanometer particle size was prepared by solid-state pyrolytic method. TEM, XRD, and surface area studies showed that the prepared zinc oxide had particle size in the range of 15–30 nm and surface area in the range of 12–30 m2/g. This nano zinc oxide was used as a curing agent in neoprene rubber.

Photoinduced adsorption of Cr(VI) ions in nano‐zinc oxide and nano‐zinc oxide/polypyrrole composite

Journal of Applied Polymer Science, 2022
AbstractZinc oxide‐polypyrrole composites (ZnO‐PPY) are novel materials that have attracted significant attention in recent years. These materials have the potential to remove hazardous pollutants from water effectively. Here, we explore facile synthesis, characterization, and adsorption capacity of hexavalent chromium anions, by nano‐ZnO and nano‐ZnO ...

Kinetics of Nano-zinc Oxide in Desert Calcareous Soils

NeuroQuantology, 2022
A laboratory experiment was carried out to study the kinetics reaction of zinc added to calcareous soils from different fertilizer sources and extracted by DTPA solution. Where two types of fertilizers were added, the first, nano-zinc fertilizers in the form of nano-metallic zinc oxide (ZnnO), nano-chelated zinc (ZnnDTPA), and nano-zinc humate (ZnnHA),

Preparation and characterization of nano-zinc oxide

Journal of Materials Processing Technology, 2007
Abstract Zinc oxide nanocrystals were prepared by homogeneous precipitation method using urea and zinc nitrate as raw materials. The orientation adhesion of nanocrystallites formed by connection of crystallites was discussed by the growth unit model of anionic coordination polyhedrons.

Toxicity of nano zinc oxide to mitochondria

Toxicology Research, 2012
Zinc oxide nanoparticles (ZnO NPs) are increasingly applied in a diverse array of industrial and commercial products. Therefore, it is urgently required to characterize their toxic behavior. ZnO NPs have been reported to induce toxic effects at the levels of the individual organism, tissue, cell and DNA.
