BACKGROUND The release of heavy metal-containing nanoparticles (NP) into the environment may be harmful to the efficacy of beneficial microbes that function in element cycling, pollutant degradation and plant growth. Nanoparticles of Ag, CuO and ZnO are of interest as antimicrobials against pathogenic bacteria. We demonstrate here their antimicrobial activity against the beneficial soil microbe...

Abstract With a high NIR reflection, transparent radiative cooling photonic structure consisting of 2D silica gratings atop ZnO/Ag/ZnO is conceived and demonstrated. 77% visible light transmitted, 57% solar radiation reflected 91% thermal infrared emitted, synthetical realized by this structure. The theoretical total power more than double that planar 63.3% higher typical reflecting filter, is,...

This study investigated the effect of zinc oxide nanoparticles (ZnO-NPs) and silver (AgNPs) on expression rsmA rsbA genes in multi-drug resistant Proteus mirabilis. The were synthesized using cell-free supernatant P. Gene levels quantified quantitative Reverse Transcription Real-Time PCR (qRT-PCR) technique. results showed that gene was significantly downregulated mirabilis isolates treated wit...

Abstract A multilayer thin film from zinc oxide and silver (ZnO/Ag film) has been synthesized via the technique of pulsed infrared laser deposition at 600 °C to be used as a portable catalyst for degradation 4-nitrophenol. The was formed by two steps; first one making with 300 nm thickness, followed 100 Ag, which characterized different characterization techniques. XRD data demonstrated presenc...

Chitosan is a natural polymer that has been widely utilized for many purposes in the food, textile, agriculture, water treatment, cosmetic and pharmaceutical industries. Based on its characteristics, including biodegradability, non-toxicity and antimicrobial properties, it has been employed effectively in wound healing applications. Importantly, however, it is necessary to improve chitosan’s ca...

We investigated the surface photovoltage (SPV) behaviors of ZnO/Ag one-dimensional (1D) nanogratings using Kelvin probe force microscopy (KPFM). The grating structure could couple surface plasmon polaritons (SPPs) with photons, giving rise to strong light confinement at the ZnO/Ag interface. The larger field produced more photo-excited carriers and increased the SPV. SPP excitation influenced t...

ZnO/Ag/ZnO nanolaminate structures were deposited by consecutive RF sputtering at room temperature.The optical transparency, sheet resistance, and figure of merit are determined in relation to the deposition time Ag film thickness ZnO top layer. An improved transmittance has been found visible spectral range structure compared multilayers without Ag. High 98% 550 nm, resistance 8 Ω/sq, (FOM) 11...

Abstract A cerium/silver/zinc oxide (Ce/Ag/ZnO) inorganic nanocomposite was synthesized through a homogeneous precipitation method. The characterization and photocatalysis procedures were carried out by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), UV-Vis diffuse reflection photocatalytic performan...

In this article we present a new type of 1D nanostructures consisting of supported hollow ZnO nanorods (NRs) decorated with Ag nanoparticles (NPs). The 3D reconstruction by high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) electron tomography reveals that the Ag NPs are distributed along the hollow interior of the ZnO NRs. Supported and vertically aligned Ag-N...
