Photoinduced adsorption of Cr(
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 ...

Preparation and characterization of nano-zinc oxide
Journal of Materials Processing Technology, 2007Abstract 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, 2012Zinc 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.

Immobilization of diastase α-amylase on nano zinc oxide
Food Chemistry, 2016Diastase 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 ...

Lasing Characteristics of Nano-structured Zinc Oxide
MRS Proceedings, 2006ABSTRACTHighy-quality nano-structured ZnO samples have been synthesized by simple chemical solution and post-thermal treatment. The samples were characterized by x-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), temperature-dependent photoluminescence (PL) spectra measurements. XRD patterns illustrated

Sintering studies of nano-crystalline zinc oxide
Ceramics International, 2008Abstract Sintering and grain growth of nano-crystalline undoped ZnO has been studied in detail over a wide range of temperature and holding time. Below 800 °C, sintering of over 70% theoretical density is not observed, irrespective of particle size.

Nano zinc oxide for UV protection of textiles
International Journal of Technology Transfer and Commercialisation, 2008This paper describes the effect on the fading of dyed polyester fabrics in artificial sunlight, when the Ultra Violet (UV) component of the radiation was blocked by coating the fabric with zinc oxide nanoparticles, dispersed in an acrylic polymer. Zinc oxide is photoactive and generates superoxide and hydroxyl radicals (Reactive Oxygen Species; ROS ...

Environmental Monitoring and Assessment, 2019
Multiple applications of nanoparticles (NPs) could result in their potential release into agricultural systems and raised concerns about food safety. The NPs once released in the environment may interact with numerous pollutants, including other NPs. Present study assessed the impact of a single (CuO and ZnO NPs) and binary mixture (CuO+ZnO NPs) on the

The Application of Nano-zinc oxide in Petrochemical
Advances in Engineering Technology ResearchIn today’s world, fossil fuels dominate the energy supply. However, petroleum refining produces many toxic gases, including sulfur oxides, which have caused many serious environmental and health problems. To reduce this negative externality, petroleum firms use desulfurizers to absorb the sulfur.
