The present study investigates the synthesis and analysis of zinc oxide nanoparticles (ZnO NPs) intended for use in electronic devices. ZnO NPs with an average crystallite size of 33 nm and a hexagonal wurtzite structure were produced by the combustion process. Scanning Electron Microscopy (SEM) revealed a densely packed, spherical morphology.

In this study, green-synthesized zinc oxide nanoparticles (ZnO NPs) were surface-modified with pluronic F-127 after being synthesized using the leaf extract of guava (Psidium guajava). The resulting material, ZnO@F-127, was then characterized, and its anticancer activity was evaluated on several cell lines.

The objective of this study is to synthesize ZnO and Mg doped ZnO(Zn1−xMgxO) nanoparticles via the sol-gel method, and characterize their structures and to investigate their biological properties such as antibacterial activity and hemolytic potential.Nanoparticles (NPs) were synthesized by the sol-gel method using zinc acetate dihydrate (Zn(CH3COO)2.2H2O) and magnesium acetate tetrahydrate (Mg(CH3COO)2.4H2O) as precursors. Methanol and monoethanolamine were used as solvent and sol stabilizer, respectively.

In this study, biogenic copper and zinc oxide nanoparticles (G-ZnONPs and G-CuONPs) were synthesized by the green synthesis method using Malva parviflora L. (Millow) leaf extract and the obtained nanoparticles were characterized in detail with UVVis, FTIR, SEM, XRD. The antibacterial properties of the synthesized nanoparticles on gram-positive and gram-negative bacteria were investigated and it was found that the nanoparticles had high antimicrobial activity in the results of the experiments.

In this study, effects of graphene oxide (GO) and ZnO nanoparticles on the properties of acrylic polymer (R4152) coating were investigated. SEM images indicated that ZnO nanoparticles distributed uniformly on GO sheets. Hence, GO/ZnO could be dispersed homogenously in the acrylic polymer matrix while ZnO nanoparticles were agglomerated in acrylic polymer matrix in the absence of GO.

In this work, we report our recent development of sol- gel and spin- coating methods to prepare thin films ZnO- SiO2 : Er3+. The characteristic PL spectra Er3+ ions are presented. The effect of temperature, doping concentration on the optical properties of the materials are annalyzed and discussed. The efficient energy transfer from ZnO nanoparticles to Er3+ ions involves to efficient PL emission is also observed.

Zinc (Zn) is a micronutrient, which is involved in activating many physiological and biochemical processes. Inadequate supply of Zn affects crop growth, development and in turn yields. Most of us depend on agriculture based foods which are grown under inadequate Zn supply and hence we get less of Zn as recommended. A few strategic approaches are being adapted to overcome inadequacy of Zn in food. Biofortification is one of the best strategies to enhance the Zn content in the food grain.

Edible films and coating are being widely studied as they have the potential to preserve the fresh produce, and are biodegradable. Taking this into account the aim of this study was to develop and evaluate the film properties such as thickness, percentage transmittance, mechanical properties such as percentage elongation and tensile strength, and sealability of the nanocomposite edible films based on aloe vera gel, glycerol and nanoparticles solution. After this all the film formulations were applied as a coating of Mango (Mangifera indica L.) and stored for 9 days at room temperature.

In this paper, an epoxy-based composite coating containing various combinations of zinc oxide submicrometer particles and organobentonite nanoparticles were prepared. Dispersion of zinc oxide particles with organobentonite nanoparticles within the composites were evaluated using XRD analyses. Hardness, adhesion, physical properties and corrosion resistance of composites were studied. The results showed that simultaneous use of low-loading fillers have a positive effect on the clay exfoliation behavior in resulting nanocomposites.

The commercial nanoparticles ZnO with - P63mc hexagonal structure, particle size of hundreds of nanometer and band gap energy about of 3.26 eV have been used on photocatalyst for methylene blue. The results showed that: as increasing irradiated time from 30 minutes to 120 minutes by 365 nm radiation of Narva LT 18W ultra - violet lamp, the color of methylene-blue and ZnO mixture were depleted gradually, in which the absorptance and photoluminescence intensity were also decreased.

In this paper, Fe3O4-ZnO heterostructure multifunctional nanoparticles (NPs) were successfully prepared in aqueous solution by ultrasound assisted thermolysis. First, iron oxide (Fe3O4) magnetic NPs were prepared by co-precipitation method. The Fe3O4 NPs were modified by 3-aminopropyltriethoxysilane (APTES) to have free amine (-NH2) groups on their surface, then, Zn2+ ions were added and stirred to adsorb onto the surface of Fe3O4-NH2 NPs in alkaline solution at a pH of 11.
