Mixed crystal of ammonium dihydrogen phosphate (ADP) and potassium dihydrogen phosphate (KDP) has been grown using aqueous solution method by temperature lowering seed rotation technique. The grown mixed crystal has a positive temperature coefficient of solubility. Metastable zone width and induction period have been determined and analysed. The lattice parameters of the grown mixed crystal have been obtained by single-crystal X-ray diffraction analysis. The optical transmission spectrum of the mixed crystal was recorded using UV-Vis-NIR spectrum. Second-harmonic generation (SHG) studies were carried for the pure ADP, KDP and ADP: KDP (85:15) mixed crystals. It was found that the SHG efficiency of the mixed crystal is 1.5 times that of pure KDP. The dielectric measurements were used to analyse the dielectric constant and dielectric loss of the mixed crystal.

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.
