Several epoxy nanocomposites incorporating layered silicates and fly ash based geopolymer were analysed by utilising the wide angle X-Ray diffraction (XRD) to characterise the nanoscale dispersion of the layered silicates. The morphological study of the nanocomposites using X-ray diffraction was an operative method to identify exfoliated and intercalated structures in the nanocomposite. It was discovered that the exfoliated structure was observed in the nanocomposites filled with montmorillonite (MMT) and fly ash-based geopolymers; while the intercalated structure was found in the nanocomposites with 3wt% of MMT. The results suggest that that the addition of fly ash-based geopolymers into epoxy/MMT mixture may contribute to superior compressive properties, in comparison to those nanocomposites without geopolymer filler addition.

L-Histidine Barium Chloride dihydrate (LHBC), a semi organic nonlinear optical material was grown from aqueous solution by slow solvent evaporation method at room temperature.  The LHBC crystals were characterized by X-ray powder diffraction analysis.  The presence of functional groups was identified through Fourier Transform Infrared Spectroscopy.  Thermogravimetric and Differential Thermal Analysis confirm that the crystal is stable up to 269oC.  The mechanical properties of the grown crystals have been studied using Vickers microhardness test.  The second harmonic generation behavior of LHBC crystal was tested by Kurtz-Perry powder technique.

Single crystals of pure and Lanthanum doped L-Alanine Tartrate were grown by slow evaporation method. The cell parameters were determined using single crystal X-ray diffraction method. To improve the physical properties of the LAT crystal, Lanthanum dopant was added by 2 mol%. ICP studies confirm the presence of Lanthanum in the grown LAT crystal. Transparency range of the crystal was determined using UV-VIS-NIR spectrophotometer. The functional groups of pure and doped LAT crystals were analyzed by FT-IR spectroscopy. Using Vickers microhardness tester, mechanical strength of the material was found. Dielectric studies of pure and doped LAT single crystals were carried out. The doped LAT crystal is found to have efficiency higher than that of pure LAT crystal.
