Abstract:

Zinc sulfide is a material that has many uses in various fields. Zinc sulfide is deriving from the mineral sphalerite. The purpose of this study was to evaluate the feasibility of producing zinc sulfide from zinc acetate and sodium sulfide using the precipitation-assisted ultrasonic radiation method. This method is the most efficient method for the synthesis of zinc sulfide nanoparticles, because it does not take much time and the resulting product is high. The evaluation was done from the engineering and economic perspectives. The feasibility analysis method from the engineering perspective was done by designing the initial production design on a large scale, whereas the analysis from an economic perspective was done by calculating various economic parameters, that is Gross Profit Margin, Cumulative Net Present Value, Internal Rate Return, Payback Period, Break Event Point, and Profitability Index. The engineering perspective showed that the production of zinc sulfide nanoparticles can be done on a large scale due to the commercial availability of materials and tools. Based on the economic evaluation, the production of zinc sulfide nanoparticles by precipitation-assisted ultrasonic method is ideal for an industrial scale. Earned increased profits over 20 years, the payback on investment costs lasted only two years. We hope that this study can provide references to readers, industry, and researchers regarding the feasibility analysis of the production of zinc sulfide nanoparticles using the precipitation-assisted ultrasonic radiation method

Abstract:

Cadmium sulfide (CdS) and zinc sulfide (ZnS) nanostructures were formed by means of electrophoretic deposition of nanoparticles with mean diameter of 6 nm and 20 nm, respectively. Nanoparticles were prepared by a microwave assisted synthesis in aqueous dispersion and electrophoretically deposited on aluminum plates. CdS thin films and ZnS one-dimensional nanostructures were grown on the negative electrodes after 24 hours of electrophoretic deposition at direct current voltage. CdS and ZnS nanostructures were characterized by means of scanning electron (SEM) and atomic force (AFM) microscopies analysis. CdS thin films homogeneity can be tunable varying the strength of the applied electric field. Deposition at low electric field produces thin films with particles aggregates, whereas deposition at relative high electric field produces smoothed thin films. The one-dimensional nanostructure size can be also controlled by the electric field strength. Two different mechanisms are considered in order to describe the formation of the nanostructures: lyosphere distortion and thinning and subsequent dipole-dipole interactions phenomena are proposed as a possible mechanism of the one-dimensional nanostructures, and a mechanism considering pre-deposition interactions of the CdS nanoparticles is proposed for the CdS thin films formation.

Abstract:

Doped ZnS nanocrystals have attracted attention since 1994. Previous results suggest that doped semiconductor nanocrystals form a new class of luminescent materials, which have a wide range of applications in displays, lighting, sensors and lasers. In this work we synthesized Y3+ doped ZnS nanoparticles by a chemical precipitation method. The reaction was performed with ZnSO4, Na2S, phosphates and Yttrium acetate in aqueous solution. Fluorescence (FL) studies of these nanoparticles have been carried out. FL analysis reveals that the incorporation of Yttrium and phosphates to colloidal solution of ZnS nanoparticles enhances the FL signal by 6-7 times of magnitude compared with uncapped ZnS nanoparticles.

Abstract:

Dissimilatory reduction of sulfate, mediated by various species of sulfate-reducing bacteria (SRB), can be used to remediate acid mine drainage (AMD). Hydrogen sulfide (H2S/HS-) generated by SRB can be used to remove toxic metals from AMD as sulfide biominerals. For this, SRB are usually housed in separate reactor vessels to those where metal sulfides are generated; H2S is delivered to AMD-containing vessels in solution or as a gas. This allows more controlled separation of metal precipitation and facilitates enhanced process control. Industries such as optoelectronics use quantum dots (QDs) in, for example, light emitting diodes and solar photovoltaics. QDs are nanocrystals with semiconductor bands that allow them to absorb light and re-emit it intensely at specific wavelength couples. Small nanoparticles have the possibility to get electrons shifted to a higher energy and then emit light during the relaxation phase. The QD elemental composition and the presence of doping agent determines its electronic band gaps and can be used to tune the QD to desired emission wavelengths. Traditional QD production at scale is costly and/or complex. Waste H2S gas from growth of SRB has been used to make zinc sulfide QDs which are indistinguishable from ’classically’ prepared counterparts with respect to their physical and optical properties. Clean recycling of minewater bioremediation process waste gas into high value QD product is described.

Abstract:

nanosized zinc sulfide (ZnS) is a special property semiconductor material widely used in many applications such as catalyst, light emitting diode, transistor, gas sensors, biosensors, UV-light sensors, and photovoltaic cell. The wet chemical method is a simple and low-cost method to prepare nanosized zinc sulfide. However, the wet chemical reaction using sodium sulfide without surfactant or template has rarely been reported. In the present work nanosized zinc sulfide particles were synthesized by simple wet chemical reaction method at room temperature and without any surfactant. The influence of sulfur source, sodium sulfide and potassium sulfide used as the reactant were investigated. The samples were characterized by scanning electron microscopy coupling with energy-dispersive X-ray spectroscopy (FESEM-EDX), and transmission electron microscopy (TEM). The results show that the nanoparticles of zinc sulfide were obtained from sodium sulfide and potassium sulfide with particles sizes are in the range of 10 to 50 nm and 25 to 50 nm respectively. In addition, from FESEM microphotograph the primary ZnS particles size of around 5 nm and 25 nm were obtained by 10% salt (sodium chloride, potassium chloride, sodium acetate) addition with sodium sulfide and potassium sulfide reactant respectively.

Abstract:

Green synthesis of materials such as nanoparticles pose several advantages including greener and lesser volume of waste generation making it a less hazardous and eco-friendly alternative. Nanoparticles have been used widely for treatment of wastewater. In the study, synthesis of zinc sulfide (ZnS) nanoparticles were conducted through green synthesis using Jatropha curcas Linn latex and its photocatalytic activity in degrading methylene blue was determined. Synthesized zinc sulfide nanoparticles were characterized based on its absorbance and average size determined through microscopic analysis. Absorbance analysis showed that there is dependency on the concentration of nanoparticles and latex formulations used. The average size of the synthesized nanoparticles is 80 nm. By monitoring changes in absorbance for 90 minutes, the photocatalytic degradation was determined. Photocatalytic degradation activity of 7.72% was recorded during the first 15 minutes which was the highest reading obtained. These findings suggest that nanoparticles synthesized thru green synthesis may be developed as an eco-friendly and non-hazardous materials for wastewater treatment.

A series of zinc oxide-modified mesoporous SBA-15 materials were synthesized. The desulphurization test with a gas mixture containing 0.1 vol % hydrogen sulfide was carried out on these materials. Materials before and after the desulphurization test were analyzed using a variety of characterization techniques. The results suggest that zinc oxide modification can accelerate the transformation from a mesoporous to a zeolitic phase. The sample with the zinc content higher than 15.5 wt % shows the highest hydrogen sulfide breakthrough capacity up to 177.3 mg S/g.

Abstract:

Aims Nanoparticles (particles with a diameter of 10-500 nm) are currently used in the cosmetics industry as well as for pharmaceuticals, diagnostic imaging, and tissue engineering. Since these nanoparticles are used in industry and drug delivery, they can also be used by pregnant women. Thus, the current study investigated the teratogenic and cytotoxic effects of Zinc Sulfide (ZnS) nanoparticles on the embryo and their fibroblastic cell culture. Methods & Materials Zinc sulfide (ZnS) nanoparticles were synthesized. Then, nanoparticles at the concentrations of 5, 10, 15, 30, and 40 mg/mL/egg were injected into the air sac of the eggs in three replicates on the third day of incubation. Next, the treated and control eggs, on day 19 of incubation were opened, and embryos were weighted, and the relevant mortality rate was recorded. Fibroblast cells were isolated, cultured, and treated from the control embryo, and morphological changes and cell survival percentages were recorded. Findings The obtained results revealed that the embryos’ survival rate depends on the nanoparticle concentration. As a result, at the highest concentration, only 36.32% of the embryos survived, and the lethal dose 50% (LD50) was equal to 32.47 mg/egg. Morphological study of the treated embryos club foot and skeletal staining suggested the deletion of caudal vertebrate. The cytotoxicity study results of ZnS nanoparticles on fibroblastic cells indicated the survival fractions of 88.45%, 68.75%, and 49.32%, respectively, and its IC50 value was measured aas1460 μM. Conclusion The present study results suggested that ZnS nanoparticles had no significant toxic effects on the embryos and culture of chicken fibroblastic cells at low concentrations.

Abstract:

The effect of chitosan as a capping agent on the synthesis of ZnS nanoparticles via wet chemical route was studied. The used of chitosan as a capping agent for ZnS nanoparticles had allow the synthesis to be carried out in water which is a more simple and environmental friendly. In dilute acetic acid, the amines in the chitosan will protonated to become NH3+ ions. The positive charges around the ZnS nanoparticles are then used to disperse the nanoparticles via electrostatic repulsion. Chitosan also has an effect on the size of produced nanoparticles. From the X-ray analysis found that the crystallite size of nanoparticles decreases with the increasing of the chitosan concentration. The increase in chitosan concentration will promote the growth of the nanoparticles and subsequently produced smaller nanoparticles.

Abstract:

Single-step ultrasound-assisted synthesis of Copper Zinc Tin Sulfide nanoparticles (CZTS) has been studied at two different frequencies. While the effects of frequency on the particle size of the CZTS nanoparticles were insignificant, a noticeable change was observed in composition. As-obtained particles presented the amorphous nature and spherical morphology with a high degree of agglomeration. Annealing of the synthesized CZTS nanoparticles increased the crystallinity while the sulfur content decreased considerably. The poly-dispersity and agglomeration of the nanoparticles increased upon annealing. The as-obtained CZTS nanoparticles synthesized at 45 kHz frequency presented a copper deprived and zinc-rich composition suitable for higher photo-conversion efficiency of the solar cells. The bandgap of the annealed and non-annealed particles ranged between 1.25 eV and 1.65 eV.

Abstract:

Abstract. The effectiveness of zinc oxide (ZnO) nanoparticles as filtering media for controlling the levels of hydrogen sulfide (H2S), ammonia (NH3), and odor in swine facilities was evaluated in this study. Semi-pilot scale tests were done to determine basic operational factors, the results of which showed that the fluidized bed air filtration system (FBAFS), loaded with ZnO nanoparticles at a rate of 0.28 g cm-2 of filter area, and a gas flow rate equivalent to 0.5 m s-1 face velocity achieved significant reduction in target gas levels. The performance of this filter system was further investigated in a room-scale environmental chamber representative of normal swine production conditions. When installed as part of the ventilation air recirculation system of the room, the FBAFS with ZnO nanoparticles achieved about 65% H2S and 42% NH3 reductions in the human-occupied zones but had no significant impact on pig performance as well as odor levels in the chamber. Keywords: Ammonia, Face velocity, Filtration, Hydrogen sulfide, Nanoparticles, Odor, Swine, Ventilation, Zinc oxide.

Abstract:

Using microwave-assisted solid-state method, a series of zinc oxide-modified mesoporous SBA-15 materials were synthesized. The desulphurization test with a gas mixture containing 0.1 vol % hydrogen sulfide was carried out on these materials. Chemicals before and after the desulphurization test were analyzed using nitrogen adsorption, XRD, EDS, TEM, ICP and other standard methods. The results suggest that zinc oxide modification can accelerate the transformation from a mesoporous to a zeolite phase. The different zinc loading results in different zinc-phase dispersions on the materials.

Abstract:

The paper presents on the synthesis and optical properties of mesomorphic composites, based on a glassy liquid-crystalline caprylate matrix, with CdSе/ZnS hetero-nanoparticles. The synthesis of complex core-shell semiconductor nanoparticles was carried out by fusing together a cadmium caprylate composite with CdSе nanoparticles and zinc caprylate composite with ZnS nanoparticles. The cadmium and zinc chalcogenide nanoparticles have been synthesized in molten cadmium caprylate and zinc caprylate respectively. It has been found by optical spectroscopy that the have hetero-nanoparticles a core-shell structure. The effect of the composition (molar ratio of the components) of CdSе/ZnS hetero-nanoparticles on their spectral characteristics has been studied. It has been shown that the nanocomposites with hetero-nanoparticles are characterized by a more intense exciton fluorescence band than composites with individual CdSе or ZnS nanoparticles. It has been found that by varying the hetero-nanoparticle composition, one can change the core-shell thickness ratio and adjust thereby the absorption and emission band edge. As the number of ZnS nanoparticles in CdSе/ZnS hetero-nanoparticles increases some narrowing of the long- wavelength emission region first takes plase, which may be attributed to a reduction in the recombination of the smaller number of surface trapped exciton, and then, at a large ZnS content, a broadening of the long- wavelength emission region takes plase due to the extended CdSе/ZnS surface. It has been found that the main contribution to the exciton fluorescence of nanocomposites with CdSе/ZnS hetero-nanoparticles is made by cadmium selenide nanoparticles, and that zinc sulfide nanoparticles enhance exciton fluorescence, also due to decrease in surface emission. It has been shown that the nanocomposites with hetero-nanoparticles are characterized by a more intense exciton fluorescence band that the nanocomposites with individual CdSе. The highest emission is observed in the case of the 35-55 % ZnS content of the shell, and at a smaller or larger amount of ZnS, emission intensity decreases.

Abstract:

Immiscibility between dimethyl sulfoxide (DMSO) and polar solvents used for poly(N-vinylcarbazole) (PVK) solutions, leads to failed light-emitting diodes when colloidal cadmium sulfide (CdS) nanoparticles capped with thiophenol are incorporated to their active layer. To prevent this, a heat treatment is applied to the CdS nanoparticles in order to evaporate DMSO solvent. After evaporation most of the nanoparticles increased their size, and some of them show hexagonal crystalline structure instead of the original cubic zinc-blende observed in colloidal pre-treated nanoparticles. Nevertheless, enhanced electronic properties are measured in light-emitting devices when DMSO-free nanoparticles are embedded in the poly(N-vinylcarbazole) active layer. Light emission from these hybrid devices comprises the whole visible range of wavelengths as searched for white LEDs. Moreover, electroluminescence from both types of CdS nanoparticles (smaller cubic and bigger hexagonal) has been discriminated and interpreted through Gaussian deconvolution.

Abstract:

Synthesis of nanoparticles doped with various ions can significantly expand their functionality. The conditions of synthesis exert significant influence on the distribution nature of doped ions and therefore the physicochemical properties of nanoparticles. In this paper, a correlation between the conditions of synthesis of manganese-containing cadmium sulfide or zinc sulfide nanoparticles and their optical and magnetic properties is analyzed. Electron paramagnetic resonance was used to study the distribution of manganese ions in nanoparticles and the intensity of interaction between them depending on the conditions of synthesis of nanoparticles, the concentration of manganese, and the type of initial semiconductor. The increase of manganese concentration is shown to result in the formation of smaller CdS-based nanoparticles. Luminescent properties of nanoparticles were studied. The 580 nm peak, which is typical for manganese ions, becomes more distinguished with the increase of their concentration and the time of synthesis.

Abstract:

Thin films based on limited solid solutions of cadmium and zinc sulfides have been synthesized by a one-stage epitaxial layer-by-layer deposition from an ammonium-containing aqueous solution of cadmium and zinc chlorides and thiocarbamide on a glass substrate. The thickness control of sulfide layers was carried out by selection of reagent concentrations and the deposition conditions. The relationship between the synthesis conditions of CdxZn[Formula: see text]S thin films and the size of sulfide nanoparticles in these films is established. The films contain two phases: hexagonal (space group [Formula: see text]) phase with [Formula: see text] structure of wurtzite type and cubic (space group [Formula: see text]-[Formula: see text]) phase with [Formula: see text] structure of sphalerite type. It is shown that the CdxZn[Formula: see text]S film consists of separate [Formula: see text][Formula: see text]nm agglomerates which are a collection of smaller nanometer-sized particles. The dependence of the band gap of the synthesized films on their thickness is found.
