Thiourea cadmium-zinc sulphate (CZTS), a semi-organic nonlinear optical material has been grown from solution by slow evaporation technique. Solubility of the synthesized material has been determined for various temperatures using water as solvent. Single crystal X-ray diffraction studies confirm that the grown crystal belongs to the triclinic system. The surface morphology and facets of the as-grown crystal were studied by contact goniometry. Functional groups present in the sample were identified by FTIR spectral analysis. Microhardness and etching studies have been carried out on the grown crystals. The SHG relative efficiency of thiourea cadmium-zinc sulphate crystal was found to be 1.8 times higher than that of KDP.

African padauk wood having inner color light sandal and outer yellowish orange is characterized using Fourier Transform Infrared (FTIR) spectra, Powder X‐ Ray Diffraction (P‐XRD) and thermal analysis. The FTIR analysis confirms the presence of cellulose, lignin and hemicelluloses. Also outer part of the wood is more lignified than inner part. P‐XRD analysis reveals inner part of the padauk wood is less crystalline than outer part. Compression test shows that the outer part of the sample is having compression strength around 3.6 times than that of the inner one. Hence inner part can be used for pulp and paper industries while outer part can be used for construction. From thermal analysis, both the parts of the sample shows different values of glass transition temperature, different steps of mass loss and different values of residues after decomposition. Hence they are physically distinct. From the thermal analysis it is concluded that outer part can be used as carbon sink.
