Abstract :

A series of N-aryl-2-[(2-aryl-1, 3-benzoxazol-5-yl) carbonyl] hydrazine carbothioamides (4a-p) were synthesized on refluxing 2-aryl-1, 3-benzoxazole-5-carbohydrazides with aryl isothiocyanates starting from methyl-4-hydroxy-3-amino benzoate via synthesis of intermediate 2-aryl-1, 3-benzoxazole-5-carbohydrazides. The compounds were characterized by 1H NMR, IR spectra and by means of C, H, and N analysis.

Abstract :

This article focused on the factor of time in separation process of rare earth elements (REEs) between solid phase and leaching sample of Iran Saghand's uranium mine. First, sufficient amount of samples were been collected from the region and analyzed. Then the acid leaching process was used for the selected sample. In this method, separating REEs from the minerals can be done easily and selectivity. As a result of this separation the obtained amounts include 500 ppm Yttrium, 580 ppm Cerium and 940 ppm Lanthanum. However, ion exchange method with fixed bed is an appropriate technique to separate REEs. Therefore, 0.5 cc Dowex 5owx8 (H+) solid phase have been brought in to 50cc of leaching solution for 10 to 60 minutes. This experiment includes two stages, absorption and efficiency stage, only absorption stage has to be used. The sample analysis showed that maximum of absorption amount obtained for 475 ppm Yttrium, 290 ppm Cerium and 658 ppm Lanthanum in 30 minutes.

Abstract :

A one-dimensional Lanthanum sulphate [C4H16N3]2 [La2(SO4)6], I, has be prepared by interacting diethylenetriamine sulphate with La3+ ions at 100oC. The compound has been characterized with the help of powder x-ray analysis, scanning election microscopy, and infrared spectroscopy. The thermal behaviour of compound I has been studied by thermogravimetric analysis. Compound I crystallizes in monoclinic symmetry, space group P21/c (No. 14) with cell parameters a = 8.3305, b = 17.5000, c = 9.8407Å, ß = 101.610, vol = 143461Å. The inorganic framework [La2(SO4)6]6 - is anionic and charge compensation is achieved by incorporation of two molecules of fully-protonated diethylenetriamine.

Abstract :

Thin films of Cu4SnS4 were grown by chemical bath deposition technique. The deposition parameters such as bath temperature (50 °C), deposition time (120 min), electrolyte concentration (0.05 M) and bath pH (pH 1.5) were optimized to obtain good quality of films. The thin films were characterized using X-ray diffraction and atomic force microscopy in order to study the structural and surface morphological properties. The band gap energy, transition type and absorption properties were determined using UV-Vis Spectrophotometer. The X-ray diffraction analysis showed the presence of polycrystalline in nature and the most intense peak occurred at 2q = 30.2° which belongs to (221) plane of Cu4SnS4. Atomic force microscopy image reveals that grains are uniformly distributed over the surface of substrate. An optical absorption study shows the presence of direct transition with band gap energy of 1.6 eV.

Abstract :

Mixed ligand four coordinated tetrahedral complexes of palladium (o) and platinum (o) with 3-(4-pyridyl) - Triazoline ­5-thione and triphenyl phosphine have been prepared and characterised on the basis of elemental analysis, electronic, infrared and far-infrared spectral data. The shifting and change in intensity of four thioamide bands of ligand are used as diagnosis for metal-ligand bonding. Metal ligand vibrations in the far-infrared spectra of complexes have been located and reasonably assigned.

Abstract :

In order to find out suitable of water for safe drinking, domestic and irrigational purpose the chemical analysis of groundwater at the prominent residential sectors of outer skirts of Kota City, an important city of Rajasthan state of India, has been carried out and presented in this paper. For this purpose ground water were systematically analysed following the standard methods and procedures during pre-monsoon period in 2006. It was observed that on some locations of the outer skirts of Kota City have poor water quality status due to seepage of effluent from industries into the ground water table, poor maintenance of sewer lines and leachates travel due to solid waste dumping in and around the study area.
