Preparation of ZnS nanoparticles by ultrasonic radiation method

Ultrasonic-assisted Method for Preparation of Cu-doped ZnS Nanoparticles in Water as a Highly Efficient Visible Light Photocatalyst

Ultrasonic-assisted method was applied for preparation of Cu+2-doped ZnS nanoparticles (mole fractions of Cu+2 ions are 0.000, 0.015, 0.030 and 0.060) in water as a template-free and green method at 30 min. The prepared nanoparticles were investigated by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and UV–Vis diffuse reflectance spectra (DRS)...

Development of a Mild Hydrothermal Method toward Preparation of ZnS Spherical Nanoparticles

Preparation of ZnO and ZnS nanoparticles and in-vitro study of their antimicrobial effect

Zinc sulfide (ZnS) & zinc oxide (ZnO) nanoparticles was evaluated for their antimicrobial activity against four pathogenic strains. ZnS&ZnO nanoparticles were synthesized by simple aqueous chemical reaction in an aqueous solution. The main advantage of these nanoparticles (size of 10-30 nm) was that simply could be prepared by using cheap precursors in a cost effective and high throughput manne...

CAVITATION DEPOSITION OF ZnS NANOPARTICLES INTO COMPOSITE WITH MONTMORILLONITE PARTICLES

In this paper we report on ZnS nanoparticles produced by precipitation of zinc acetate and sodium sulphide and stabilized by cetyltrimethylammonium bromide (CTAB) in aqueous media and deposited on montmorillonite (MMT). For the deposition a new method based on intensive cavitation was used. The montmorillonite carrier was first disintegrated by intense turbulent mixing in an ultrasonic field in...

Preparation of Chitosan-Copper Nanoparticles Coated Kraft Paper, Characterization and its Antimicrobial Activity

In this paper, Chitosan-copper nanoparticles were successfully coated onto the Kraft paperusing a dip coating process. First, chitosan-copper nanoparticles solution was prepared byreduction method and the use of ultrasonic radiation. It was employed copper sulphate pentahydrateas precursor salt, NaOH as a reducing agent and Chitosan as capping agent to prepareChitosan-copper nanoparticles solut...
