Synthesis of Zinc hydrogen phosphate (ZnHPO4) and Calcium doped ZnHPO4 single crystals were grown in silica gel at ambient temperature. Effect on various parameters like gel pH, and gel ageing, gel density and concentration of reactants on the growth of these crystals were studied. Crystals with different morphologies and habits were obtained. Some of them were transparent diamond, X - shaped and some are twinned. The crystals were characterized by X- Ray Diffraction (XRD), Scanning electron microscope (SEM), Fourier transform infra red (FTIR), Ultra violet (UV), Non – linear optical (NLO) and Thermo gravimetric analysis (TG-DTA). XRD study reveals that the crystal lattice of Calcium doped ZnHPO4 is orthorhombic and crystalline perfection of the crystals were extremely good. SEM image showed plate like morphology and further plate like growth was observed on some plates..

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.
