ZnS thin film properties are overviewed in this research paper. These include absorbance, transmittance, optical band gap, refractive index and structure (on the basis of X-ray diffraction and scanning electron microscopy). It has been observed that these film properties are dependent on various parameters e.g. thickness of the film, deposition method, deposition rate, substrate material, subst...

Template growth and catalytic growth are two typical mechanisms for the solution-chemistry synthesis of one-dimensional (1D) II-VI semiconductor nanomaterials. Here, we systematically demonstrate the competition relationship between them by tuning the synthesis of 1D ZnS nanostructures in different chain-length primary alkyl-amines. The template growth, derived from the coordination effect of a...

The solid state thermal, one pot, efficient chemical reaction between Zn and S or Se elements in a closed reactor at 650 degrees C/60 min under their autogenic pressure in an inert atmosphere yielded luminescent ZnS and ZnSe semiconducting nanopowders (NPs). Scanning and Transmission electron microscopy measurements confirmed the size and shape of the as formed ZnS and ZnSe NPs. The wide size d...

BACKGROUND Nanotechnology has the potential to provide agriculture with new tools that may be used in the rapid detection and molecular treatment of diseases and enhancement of plant ability to absorb nutrients, among others. Data on nanoparticle toxicity in plants is largely heterogeneous with a diversity of physicochemical parameters reported, which difficult generalizations. Here a cell biol...

Langmuir–Blodgett (LB) technique has been used to deposit composite multilayers of poly(3-octylthiophene) with cadmium arachidate (POT-CdA), zinc arachidate (POT-ZnA) and copper arachidate (POT-CuA). These composite multilayers were used as precursors to develop the respective semiconducting CdS, ZnS and Cu2S nanoclusters in the POT-arachidic acid (POT-AA) matrix. The formation of sulphide nano...

CuGaS2, (AgInS2)x-(ZnS)2-2x, Ag2ZnGeS4, Ni- or Pb-doped ZnS, (ZnS)0.9-(CuCl)0.1, and ZnGa0.5In1.5S4 showed activities for CO2 reduction to form CO and/or HCOOH in an aqueous solution containing K2SO3 and Na2S as electron donors under visible light irradiation. Among them, CuGaS2 and Ni-doped ZnS photocatalysts showed relatively high activities for CO and HCOOH formation, respectively. CuGaS2 wa...

The evolutionary processes governing variability within genomic regions of low recombination have been the focus of many studies. Here, I investigate the statistical properties of a measure of interlocus genetic associations under the assumption that mutations are selectively neutral and sites are completely linked. This measure, denoted ZnS, is based on the squared correlation of allelic ident...

Zinc sulfide (ZnS) nanoparticles were synthesized by the wet chemical method. The crystal structure and grain size of the particles were determined, using X-ray diffraction (XRD). The optical properties were studied by the Ultraviolet-Visible (UV-Vis) absorption spectrum. The dielectric properties of ZnS nanoparticles were examined using a HIOKI 3532-50 LCR HITESTER over the frequency range of ...

Abstract Over the past decade, piezoelectric nanogenerator have attracted much attention to harvest mechanical energy from abundant resources in nature. Here, ZnS microspheres is prepared by hydrothermal method and core-shell structured PANI/ZnS are synthesized situ polymerization then used as filler for preparation of flexible [P(VDF-HFP)] based nanogenerator. The P(VDF-HFP)/PANI-ZnS Electrosp...

objective(s):  medicinal benefits of quantum dots have been proved in recent years but there is little known about their toxicity especially in vivo toxicity. in order to use quantum dots in medical applications, studies ontheir in vivo toxicity is important.  materials and methods:cdse:zns quantum dots were injected in 10, 20, and 40 mg/kg doses to male mice10 days later, mice were sacrificed ...
