A comprehensive in vitro assessment of two commercial metal oxide nanoparticles, TiO2 and ZnO, was performed using human monocyte-derived macrophages (HMDM), monocyte-derived dendritic cells (MDDC), and Jurkat T cell leukemia-derived cell line. TiO2 nanoparticles were found to be non-toxic whereas ZnO nanoparticles caused dose-dependent cell death. Subsequently, global gene expression profiling...

Novel reusable magnetic carbon microspheres (MCMs) were prepared by hydrothermal method with glucose as carbon source and Fe3O4 nanoparticles as magnetic raw materials. And adsorption performance of MCMs for sulfonamide removal from water was investigated in detail. The results indicated that the calcination temperature and calcination time had significant effects on the surface area and its vo...

The effect of mechanical stirring on sol-gel synthesis of thorn-like ZnO nanoparticles (ZnO-NPs) and antimicrobial activities is successfully reported in this study. The in-house synthesized nanoparticles were characterized by XRD, SEM, TEM, FTIR, TGA, DSC and UV-visible spectroscopy. The X-Ray Diffraction analysis revealed the wurtzite crystal lattice for ZnO-NPs with no impurities present. Th...

in this work, zno/sio2 nanoparticles were prepared using sol-gel method, and platinum particles were loaded on zno/sio2 nanoparticles by photoreductive method. samples were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform infrared spectroscopy (ft-ir). the xrd patterns showed that the zinc oxide samples have a wurtzite structure (hexagonal phase...

In this paper the influence of ZnO shell thickness on the luminescence properties of Mn-doped ZnS nanoparticles is studied. Transmission electron microscopy (TEM) images showed that the average diameter of ZnS:Mn nanoparticles is around 14 nm. The formation of ZnO shells on the surface of ZnS:Mn nanoparticles was confirmed by X-ray diffraction (XRD) patterns, high-resolution TEM (HRTEM) images,...

This work focuses on the study the effect of ZnO nanoparticles on the vulcanizate properties of natural rubber (NR) latex films. Zinc oxide nanoparticles were synthesized by a simple and an efficient wet chemical method. The Powder X-ray Diffraction (PXRD) characterization confirmed the successful synthesis of pure ZnO and the average particle size was found to be 50 – 100 nm as indicated by pa...

Surface coating with an organic self-assembled monolayer (SAM) can enhance surface reactions or the absorption of specific gases and hence improve the response of a metal oxide (MOx) sensor toward particular target gases in the environment. In this study the effect of an adsorbed organic layer on the dynamic response of zinc oxide nanowire gas sensors was investigated. The effect of ZnO surface...

TiO(2) nanoparticles were directly coupled with porous silicon and this novel composite material shows very strong photocatalytic activity for the degradation of Rhodamine B with high photochemical stability under visible light irradiation.

The incorporation of Pt nanoparticles into a highly stable and porous amine-functionalized MIL-101(Cr) was performed for construction of a visible light driven H2 evolution system with high activity and strong stability.
