Growth and characterization of zinc doped bis-thiourea strontium chloride Rakesh Hajiyani, Bhoomika Jogiya, Chetan Chauhan, Harshkant Jethva, Mihir Joshi Aip Conference Proceedings, 2018 Organo-metallic crystals are good non-linear optical materials. The synthesis and characterization of zinc doped bis-thiourea strontium chloride was done using slow solvent evaporation technique at room temperature. The unit cell parameters of grown crystal were found as: a = 9.810Å, b = 10.708 Å and c = 18.070Å, α = β = γ = 90° obtained from the powder XRD pattern. FT-IR spectrum suggested the presence of stretching and bending vibrations for different functional groups present. Thermal stability of the grown crystal was studied by TGA/DTA analysis. From the TGA curve, the crystal was stable up to 190°C. The second harmonic generation efficiency of Nd:YAG laser was found to be 0.987 times that of standard KDP.
Growth, thermal and spectroscopic studies of bis-thiourea nickel barium chloride single crystals Rakesh R. Hajiyani, Chetankumar K. Chauhan, Mihir J. Joshi Asian Journal of Chemistry, 2018 Bis-thiourea nickel barium chloride was synthesized and crystals were grown by slow aqueous solvent evaporation technique. The powder XRD analysis of grown crystal was suggested to have orthorhombic crystal structure. The unit cell parameters of grown crystal as: a = 9.70 Å, b = 10.68 Å and c = 17.95 Å. The contents of nickel and barium in the grown crystals was analyzed using EDAX. The presence of various functional groups was confirmed by FTIR spectroscopy studies. From the UV-visible spectrum, the material has about 90 % optical transparency in the entire visible region. From the thermogravimetric analysis, it was found that the crystals remained stable up to 170 ºC. The endothermic reactions were identified from the differential thermal analysis.
Synthesis and characterization of struvite nano particles K. R. Rathod, B. V. Jogiya, C. K. Chauhan, M. J. Joshi Aip Conference Proceedings, 2015 Struvite, Ammonium Magnesium Phosphate Hexahydrate [(AMPH) - (NH4)MgPO4.6(H2O)], is one of the fascinating inorganic phosphate minerals. Struvite is one of the components of the urinary stones. Struvite occurs as crystallites in urine and grows as a type of kidney stone. In this study, struvite nano particles were synthesized by wet chemical technique. The aqueous solutions containing dissolved Mg(CH3COO)2.4H2O and (NH4)H2PO4 mixed at the Mg/P molar ratio of 1.00. The synthesized struvite nano particles were characterized by XRD, FT-IR, Thermal Analysis and TEM. From XRD, crystal structure of the nano particle was found to be orthorhombic and crystalline size was found to be within 11 to 26 nm. The FT-IR spectrum for the struvite nano particles confirmed the presence of a water molecule and metal-oxygen stretching vibration, O-H stretching and bending, N-H bending and stretching, P-O bending and stretching vibrations. The Thermal Analysis was carried out from room temperature to 900°C. From TEM analysis, ...
Growth and characterization of bis-thiourea strontium chloride single crystals R. R. HAJIYANI, D. J. DAVE, C. K. CHAUHAN, P. M. VYAS, M. J. JOSHI Modern Physics Letters B, 2010 Bis-thiourea strontium chloride was synthesized and single crystals were grown by the slow solvent evaporation technique using aqueous solvent. The solubility curve was obtained and the determination of the induction period as well as the evaluation of kinetic parameters of nucleation was carried out. The powder XRD analysis suggested orthorhombic crystal structure. The FT-IR spectrum confirmed the presence of various functional groups. The thermo-gravimetry analysis was carried out and the crystals were found to be stable up to 170°C. Applying Coats and Redferm relation to the thermo-gram, the kinetic and thermodynamic parameters of dehydration were calculated. The dielectric study was carried out in the frequency range of applied field from 500 Hz to 1 MHz. The variations of dielectric constant, dielectric loss, AC resistivity and AC conductivity were studied with frequency. It was found that the dielectric constant and the dielectric loss decreased as the frequency of applied field increased, whereas the AC resistivity increased as the frequency increased.
