Single crystals of Zinc tris-thiourea Sulphate (ZTS) and L-Threonine added Zinc tris-thiourea Sulphate were grown from aqueous solution by slow evaporation method. The cell parameters of the grown crystals were estimated by single crystal X-ray diffraction technique. The powder X-ray diffraction patterns were recorded and indexed for further confirmation of crystalline nature of grown crystals. The presence of functional groups has been confirmed by FTIR analysis. The UV-Vis absorption spectra have been recorded to find the cut-off wavelength. The TGA/DTA and DSC studies show the thermal behavior of the grown crystals. Microhardness study on the crystal samples revealed that the hardness number (Hv) increases with applied load for all the grown crystals. The second harmonic generation of ZTS and L-Threonine added ZTS crystals was observed by Kurtz Perry powder method using Nd:YAG laser. The crystal perfection and quality have been identified by etching studies..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
