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 ...

Grinding (solvent-free) method was used as a superior technique to prepare mesoporous photocatalysts of ZnO, ZnS, ZnO / ZnS, CdO, CdS and CdO / CdS-SBA-15. In this technique, the nitrate, acetate and chloride salts of zinc and/or cadmium were grinded with as-synthesized SBA-15 as a mesoporous material. The controllable sulfurationis was used to prepare ZnS, ZnO/ZnS, CdS and CdO/CdS-SBA-15 a...

.Zinc sulfide/carbon nanofibers ZnS/CNFs composite was successfully synthesized through a facile and simple method. The X-ray diffraction XRD patterns revealed the formation of ZnS decorated CNFs composite. The photocatalytic activity of ZnS/CNFs composite was investigated by the photodegradation of Rhodamine 6G Rh-6G dye in aqueous solutions. The effect of operational parameters such as initia...

SiO2/ZnS core/shell nanostructures have been synthesized at room temperature by a simple wet chemical method. The prepared materials are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared spectroscopy (IR), UV–vis spectroscopic and transmission electron microscopy (TEM) studies. X-ray diffraction pattern exhibits peaks correspond to the cubic phase of ZnS. Th...
