ZnS and CdS nanoparticles were prepared by a simple microwave irradiation method under mild conditions. The obtained characterized XRD, TEM EDX. results indicated that high purity of nanosized was successfully with cubic hexagonal crystalline structures, respectively. band gap energies estimated using UV-visible absorption spectra to be about 4.22 2.64 eV, Photocatalytic degradation methylene blue carried out physical mixtures 500-W halogen lamp visible light irradiation. residual...
Zinc sulfide semiconductor nanoparticles were synthesized in an aqueous solution of polyvinyl pyrrolidone via a simple microwave irradiation method. The effect the polymer concentration and type sulfur source on particle size dispersion final ZnS nanoparticle product was carefully examined. Microwave heating generally occurs by two main mechanisms: dipolar polarization water ionic conduction precursors. introduction affects rate restriction rotational motion dipole molecules immobilization...
Nanocrystalline magnesium ferrites (MgFe 2 O 4 ) were produced with an average grain size of about 20 nm. Their structural, morphological, and magnetic characterizations studied. The cytotoxic effects MgFe nanoparticles in various concentrations (25, 50, 100, 200, 400, 800 μ g/mL) against MCF‐7 human breast cancer cells analyzed. MTT assay findings suggest the increased accumulation apoptotic bodies increasing concentration a dose‐dependent manner. Flow cytometry analysis shows that g/mL are...
The present work reports a detailed mechanistic interpretation of the role solubility dopants and resultant midgap defect energies in band gap engineering. While there is general perception that single dopant associated with mechanisms, reality, potential for multiple mechanisms requires more nuanced interpretation. Similarly, Kröger-Vink equilibria assume stoichiometries during substitutional interstitial solid as well Schottky Frenkel pair formation are compensated by diffusion matrix ions...
Abstract In this article, cadmium oxide (CdO) was deposited using pulsed laser deposition approach on porous silicon (Si) wafer for visible light photodetector application, through which a series of devices were proposed as function the energy. The microstructural well optical characteristics prepared film/s demonstrated, respectively, x-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and ultraviolet spectroscopy (UV–Vis) analysis. details, UV–Vis analysis...
Holey 2D metal oxides have shown great promise as functional materials for energy storage and catalysts. Despite impressive performance, their processing is challenged by the requirement of templates plus capping agents or high temperatures; these also exhibit excessive thicknesses low yields. The present work reports a metal-based coordination polymer (MCP) strategy to synthesize polycrystalline, holey, oxide (MO) nanosheets with two-unit cells. process involves rapid exfoliation...
The La5/8Sr3/8MnO3 (LSMO) thin films were directly grown on MgO and Si wafer substrates by Pulsed Laser Deposition (PLD) technique. characterized using X-ray diffraction (XRD), field emission-scanning electron microscope (FE-SEM). electrical magnetic properties of are studied. From the XRD patterns, found polycrystalline single-phases. highest magnetoresistance (MR) value obtained was −17.21% for LSMO/MgO film followed −15.65% LSMO/Si at 80K in a 1T field. Transition temperature (TP) is 224K...
The manganite LSMO films were successfully grown on glass substrates without any additional buffer layer by pulsed laser deposition. have been investigated X-ray diffraction (XRD), field emission-scanning electron microscope (FE-SEM), electrical and magnetic measurements. From the XRD pattern film is found to be polycrystalline single-phase's character. thin growth substrate, follows island model with average grain size of 44.46nm. metal-insulator transition (TMI) temperature was above room...
