SYNTHESIS AND CHARACTERIZATION OF PURE ZINC OXIDE NANOPARTICLES AND NICKEL DOPED ZINC OXIDE NANOPARTICLES

International Journal of Research in Engineering and Technology, 2015
In this paper, Zinc oxide nanoparticles are synthesized by simple wet chemical precipitation method. Zinc nitrate and sodium hydroxide are used as the starting materials.Zinc oxide nanoparticles are formed at a very low temperature of the order of 80 0 C. Nickel doped zinc oxide nanoparticles are synthesized in two steps.

Physiology of Zinc Oxide Nanoparticles in Plants [PDF]

, 2021
Since ZnO nanoparticles (ZnO NPs) are extensively applied engineered nanomaterials, e.g. in cosmetics or therapeutics due to their anticancer or antimicrobial effect, their emission to the environment has grown. Although there are several examples for “green” synthesis of ZnO NPs applying various plants or plant extracts, numerous studies exhibited ...
