Single crystals of sulphanilic acid have been grown from aqueous solution by doping with L-proline and L-lysine monohydrochloride dihydrate by solvent evaporation technique, with the vision to improve the physiochemical properties of the sample. The characterization of the grown crystals were made by X-ray diffraction analysis and FTIR spectral analysis. Thermal analysis was performed to study the thermal stability and the maximum temperature for non linear optical applications of sulphanilic acid in the presence of dopants. Transmission range of the grown crystals were determined by UV-vis-NIR measurements. Frequency response of the dielectric constant and dielectric loss factor have been studied over the frequency range of 100Hz - 5MHz. Second harmonic generation (SHG) was confirmed in all the samples using the Kurtz and Perry powder technique. Thus the pure and doped single crystals of sulphanilic acid make them suitable for photonic device application..

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.
