Two new antimony telluride single source precursors (SSPs), Ph2SbTeR (R = Et, Ph), have been used to synthesise pure and defect free hexagonal Sb2Te3 nanoplates by thermal decomposition in an organic solvent. The chemical composition of the SSPs plays an important role in the formation of antimony telluride nanocrystals.

sulphide was determined spectrophotometrically at 628 nm and ph 6.7 based on its catalytic reduction of toluidine blue in the presence of se(iv) using a flow injection system. after optimization of the measuring conditions the calibration curve was found linear up to 25 mg/ml and the detection limit was 0.3 mg/ml (30 ml injections). the relative standard deviation for the determination of 10 mg...

Emergence of resistance to pentavalent antimonials has become a severe obstacle in the treatment of visceral leishmaniasis (VL) in the Indian subcontinent. Mitogen-activated protein kinases (MAPKs) are well-known mediators of signal transduction of eukaryotes, regulating important processes, like proliferation, differentiation, stress response, and apoptosis. In Leishmania, MAPK1 has been shown...

The effects of grain size and strain on the temperature-dependent thermal transport of antimony telluride (Sb2Te3) thin films, controlled using post-annealing temperatures of 200°C to 350°C, were investigated using the 3-omega method. The measured total thermal conductivities of 400-nm-thick thin films annealed at temperatures of 200°C, 250°C, 300°C, 320°C, and 350°C were determined to be 2.0 t...

In today’s world of electronics, nanomaterial applications pose a challenge. The spin coating approach was used to create nanostructured ZnO with wurtzite structure in recent study. Antimony doping, aluminum, and antimony codoping 2.0 percent were make these films. impact doped codoped films on structural, optical properties, morphological has been examined using variety characterization approa...

Manure pits and silos are potentially dangerous, gas-containing confined spaces on the farm that may generate hazardous levels of hydrogen sulphide and nitrogen dioxide respectively. Although these inhalation injuries are uncommon, emergency physicians who work within transport distance of rural areas should be aware of the toxic agents involved and their acute management. This article reviews ...

Acton el al. (1932) used a vegetable medium from a green variety of mung dal (Phaseolus mungo) for cultivation of the intestinal bacteria. Brewer (1943) suggested a mixture of soyabean and cotton seed or peanut meal for the preparation of a general purpose media using sodium sulphide as an activator; the sodium sulphide would readily generate sulphuretted hydrogen which by lowering the pH of th...

In this work we report the synthesis and characterization of hybrid nanostructures of multiwall carbon nanotubes (MWCNT) and cadmium sulphide (CdS) nanoparticles. In a solution of thioacetamide and cadmium sulphide, purified MWCNT are added to prepare the CNT/CdS hetrostructure. XRD diagrams, SEM images, and also photoluminescence spectra of the prepared samples are analyzed. SEM images show th...

In surface sediments, metal mobility is controlled by the recruitment and turn-over of organic matter whereas sulphide is thought to control the concentration of metals in sediment pore water by removing them from the solution. DGT is a dynamic probe that measures the kinetically available fraction of metals or sulphide. DGT uses a credit card size probe inserted into the sediment that provides...
