research papers on zno nanoparticles

In this research ZnO NPs were synthesized via a green chemistry method using phenylalanine At the first step phenylalanine 5– sulfosalicylaldehyde sodium salt and zinc acetate dehydrate were separately solved in water The obtained solutions were then mixed and stirred to appear white sediment ZnOZnS CSNPs on any type of soft substrate it would be of interest to reduce the synthesis temperature much below 160 oC In this research paper we have fabricated an easy-to-use highly selective and sensitive test paper based on ZnOZnS core shell nanoparticles (CSNPs) synthesized using the chemical approach

A green chemical approach to the synthesis of gold nanoparticles from the Caulerpa racemosa and its biomedical applications are reported The C racemosa mediated synthesized gold nanoparticles ([email protected]) were characterized by various spectral and microscopy techniques The [email protected] exhibited a surface plasmon resonance (SPR) peak at 528 nm in UV–Vis spectrum

However the Nd–ZnO nanoparticles have reported little work on the photodegradation of organic contaminants under visible light irradiation In this paper the mainly research is focused on the preparation process and removal properties of organic pollutants Cong red from the wastewater using the Nd doped zinc oxide nanoparticles

Recent research has demonstrated strong UV and visible photoluminescence as well as optically pumped lasing in ZnO nanowires 1–4 However only a few ZnO-based electroluminescence (EL) devices have been fabricated to date using ZnO nanowires nanorods or epitaxial films due to inconvenient and expensive preparation methods 5–8 As a result stable and low-cost ZnO EL devices are still

Zinc oxide nanoparticles (NPs) are the third highest in terms of global production among the various inorganic nanoparticles and there are concerns because of their worldwide availability and accumulation in the environment In contrast zinc is an essential element in plant growth and metabolism and ZnO NPs (nano-ZnO) may have unknown interactions with plants due to their small

Dried plum-like ZnO assemblies consisting ZnO nanoparticles were synthesized by an ultrasonic spray pyrolysis method (USP) ZnO assemblies were characterized by X-ray diffraction (XRD) field-emission scanning electron microscopy (FE-SEM) energy-dispersive spectroscopy (EDS) and field-emission transmission electron microscopy (TEM)

Here we reported photoelectrocatalytic oxidation of methane into methanol over ZnO nanowire arrays (NWAs) decorated with Au nanoparticles (NPs) under simulated sunlight illumination with ambient conditions The photoelectrochemical (PEC) performances of the ZnO and ZnO/Au photoanodes were investigated to analyze the behavior and intensity of the reaction process of methane oxidation The

Optical properties of ZnO nanoparticles on p-type Si and Al2O3 substrates by utilizing a spin-coating method were investigated While the PL spectra of ZnO nanoparticles on p-type Si substrates shows only strong exciton related to near band emission peak without a green-emission peak those of ZnO nanoparticle on Al2O3 substrate shows broad green-emission spectra by defect

ZnO nanoparticles Toxicity X-rays Mesquite Uptake abstract The impact of metal nanoparticles (NPs) on biological systems especially plants is still not well under-stood The aim of this research was to determine the effects of zinc oxide (ZnO) NPs in velvet mesquite (Prosopis juliflora-velutina)
