Dental care is an essential phenomenon in human health. Oral pathogens can cause severe break which may show the way to serious issues in human disease like blood circulation and coronary disease. In the current study, we demonstrated the synthesis and antimicrobial activity of cadmium sulphide and zinc sulphide nanoparticles against oral pathogens. The process for the synthesis of cadmium sulp...

Diamond-reinforced zinc sulphide composites have increased toughness as compared to that of pure zinc sulphide. While the mechanical properties of the composites are relatively insensitive to green state processing, the optical properties are greatly affected by the processing which governs the quality of diamond dispersion. Improved dispersion and hence good optical transmission have been achi...

This work deals with the evaluation of diphenyl sulphide as a corrosion inhibitor for zinc in 0.5N HCl and 0.5N H2SO4 by conventional weight loss and gasometric methods. Results indicate that diphenyl sulphide exhibited high inhibition efficiencies in both the acids but performed better in 0.5N H2SO4 than in 0.5N HCl. The inhibition efficiency was found to increase with increase in the inhibito...

Arsenic is the 20th most abundant element in the earth's crust at a level of about 2 ppm. It is a constituent of over 300 minerals and is commonly found in non-ferrous ores such as copper, lead, zinc, gold and uranium. Efficient separation of arsenic minerals from other sulphide minerals is of great importance for the metallurgical performance of flotation processes. This work was undertaken to...

BACKGROUND/AIMS While the social significance of flatus derives mainly from its odour, previous studies have focused on the non-odoriferous components of rectal gas. The aims of the present study were to determine the role of sulphur-containing gases in flatus odour and test the efficacy of a device purported to reduce this odour. METHODS Flatus was quantitatively collected via rectal tube fr...

We demonstrate that copper-zinc-tin-sulphide nanoplatelets can be directly grown onto a molybdenum-coated substrate using spray pyrolysis starting from a mixture of metal thiocarbamates precursors. The structure and phase purity of the nanoplatelets is discussed in detail.

ABSTRACT The II-VI group semiconductors are of great importance due to their applications in various opto electronic devices. Among these semiconductor. Zinc sulphide is the most suitable for its utility in opto electronic devices. Zinc Sulphide has been prepared on glass substrate by using Spray Pyrolysis method. The optical properties of these films have been studied in the wavelength range 3...

Zinc Sulphide particle in the nanometer size regime has been synthesized using chemical routes. The particles were capped using 2-mercaptoethanol to achieve the stability and avoid the coalescence. The as-obtained particles were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), UV–VIS absorption and photoluminescence (PL) spectra. The dielectric measurements of t...

There are two crystalline modifications of zinc sulphide. The high-temperature hexagonal (e) phase and the low-temperature cubic (/~) phase exhibit a reconstructive transformation at a transition temperature of about 1020 ° C. The transformation of e phase back to ~ phase is a sluggish process compared to that of/3 to :~ [1], therefore once it is formed the a phase will remain as a metastable p...
