Abstract In this paper the synthesis of zinc sulfide nanoparticles by different routes has been discussed.
Formation of zinc sulfide nanocrystals in aqueous solutions of various polymers has been studied. The authors declare no conflict of interest. Zinc sulfide (ZnS) nanoparticles (NPs) with tunable photoluminescence (PL) emission and high photocatalytic activity have been obtained by means of a microwave-assisted solvothermal (MAS) … Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS.
A variety of chemical and physical procedures could be used for the synthesis of metal sulfide nanoparticles. Zinc sulfide nanoparticles have been synthesized using sodium dodecylsulfate micelles as a stabilizing agent. Zinc sulfide nanoparticles were prepared, characterized and loaded on commercially available activated carbon. The objective of this study was to assess the suitability and efficiency of zinc sulfide nanoparticle loaded activated carbon (ZnS‐NP‐AC) for the removal of Methylene blue (MB) from aqueous solution. Synthesis of chitosan zinc sulfide nanoparticles For the synthesis of CS-ZnS-NPs, ZnS NPs (0.25 g) were added into 50 mL of 1% chitosan solution using a 1% acetic acid solution.
A Review on Zinc Sulphide Nanoparticles: From Synthesis, Properties to Applications Keywords: Zinc sulphide; Electroluminescence; Sensors Abstract In this paper the synthesis of zinc sulfide nanoparticles by different routes has been discussed. However, these methods suffer from some disadvantages including the use of toxic solvents, generation of hazardous by-products, and high energy consumption. The zinc sulfide nanoparticles were obtained by microwave-assisted heating of a reactant mixture of zinc acetate (219.5 mg) in 1-dodecanethiol (5 g) at 300 °C for 25 min. Metal sulfides are considered as stable species in the environment, while transformation and risk of nanoparticles have attracted increasing attention due to their specific physicochemical properties compared to bulk materials. The aim of the present study was to develop zinc sulfide nanoparticles (ZnS NPs) and to study their cytotoxicity against the KG‐1A (human acute myeloid leukemia) cell line. EDAX analysis confirmed the presence of Zinc and Sulphur while the FTIR study affirmed the role of glycosides components as capping and stabilizing agents. The emergence of nanotechnology and the synthesis of nanomaterials have revolutionized the field of science and technology.
ZnS NPs were synthesized using the pyrolytic method and characterized by X‐ray diffraction, dynamic light scattering, surface zeta potential, scanning electron microscopy and atomic force microscopy. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite.Although this mineral is usually black because of various impurities, the pure material is …
The zinc sulfide nanoparticle was characterized by UV–vis, SEM and XRD analysis. Spectral properties of ZnS nanoparticles have been investigated, the structure of the long-wave edge of the fundamental absorption band of ZnS nanocrystals has been analyzed. Conflicts of interest. IC 50 values of ZnS nanoparticles and Stevia extract against MCF-7 cell line were 400 and 2000 μg/mL, respectively. The as-prepared nanoparticles are characterized by ultraviolet-visible spectroscopy, energy dispersive X-ray spectroscopy, X-ray diffraction and transmission electron microscopy. The mixture was sonicated for 30 min at room temperature until the NPs were homogeneously disseminated and NaOH solution (2 M) was added to precipitate CS-ZnS-NPs.
With the rapid development of nanotechnology, metal sulfide nanoparticles have been widely detected in the environment including water, soils and sediments.
