Potassium doped zinc mercury thiocyanate ZnHg(SCN)4 crystals have been grown by gel technique by diffusion process in silica gel medium in various pH values ranging between 2.0 – 2.8. The grown crystal was characterized to explore its structural, molecular and nonlinear optical properties. Fourier transform infrared spectrum (FTIR) studies were performed and the strong absorption bands due to SCN were revealed. UV-visible-near infrared spectrum was recorded and the cut off wavelength was determined. SHG studies have shown an enhancement in the conversion efficiency with respect to Voltage (V) versus Time (s). Chemical analysis was carried out using EDAX and the actual composition of the crystal material was identified. The unit cell parameters and cell volume are obtained by single crystal X-ray diffraction analysis. Thermogravimetric and differential thermal analysis were performed and the thermal stability of the crystal was analysed..

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.
