Pure and Magnesium Nitrate hexahydrate (MgN) doped Barium Nitrate (BaN) crystals were grown by slow evaporation technique. FTIR spectral studies have been carried to identify the presence various functional groups. An FTIR spectrum of grown crystals confirms the presence of ionic bonds in the structure of pure and doped BaN crystals. The influence of MgN doping on FTIR spectra was absorbing frequencies by pure and doped BaN crystals were studied. Thermogravimetric of pure and doped BaN crystals were analysed to characterise thermal stability. Thermal parameters are evaluated using thermogram. The results are presented and discussed in this paper.

The single crystal of cis-2,6-bis(4-chlorophenyl)-3,3-dimethylpiperidin-4-one (4C3DMPO) has been grown using a slow evaporation technique. 4C3DMPO is a non-centrosymmetric crystal which crystallizes in the orthorhombic system with space group Pna21. Benzene is used as a solvent for the crystal growth based on solubility studies. The mechanical studies, using microhardness methods, have also been carried out. The compound is characterised using UV, FT-IR and NMR spectral studies. Furthermore, the thermal stability of the crystal is established by TG/DTA. The nonlinear optical studies (SHG) of the crystal have been determined using the Kurtz and Perry powder technique and the activity observed is 2.5 times greater than that of KDP.

AbstractA simultaneous DSC–thermomicroscopy system (DSC450 Linkam Scientific) was applied to the study of phase transitions in rubidium nitrate and silver iodide, the oxidation of polyethylene, the thermal degradation of polylactic acid and magnesium nitrate hexahydrate, and the reversible transitions in thermochromic inks. The results demonstrated the benefits of obtaining simultaneous optical data, both images and light intensity measurements, with DSC, particularly in the interpretation of complex processes and the detection of events with small changes in enthalpy.

Evaporation Technique

Single crystals of 2-Aminothiazole 3,5-Dinitrobenzoic acid has been synthesized and good quality optical crystals were grown by slow evaporation technique at room temperature. The crystallinity nature of the grown crystal was confirmed from X-ray diffraction technique. An optical transmittance study was also carried out by UV – Vis spectra. FTIR spectra confirm the presence of functional groups in the grown crystal. The dielectric measurements were carried out in the range of 50Hz to 2MHz. The dielectric constant was seen to increase exponentially at lower frequencies. The microhardness studies were carried out using Vickers hardness indenter. Photoluminescence study shows that maximum emission occurs at 435nm.

Magnesium borate hydroxide (MgBO2(OH) ) were synthesized using magnesium nitrate hexahydrate(MgNO3.6H2O) and borax decahydrate(Na2B4O7.10H2O) by hydrothermal route. Effect of reaction temperature , reaction time and water's volume on the composition , structure , and crystal morphology of the products were investigated, and the products were characterized by XRD and SEM. The results indicated that all of the products were szaibelyite with the reaction condition investigated, and crystal morphology could be tailored via varying the reaction condition.
