L-Leucinium Oxalate, (abbreviated as LLO) an organic nonlinear optical crystal was grown from aqueous solution. Transparent crystals of size 21mm × 5mm × 4mm were obtained. The grown crystals were characterized with single crystal X-Ray diffraction. The Powder X – Ray Diffractogram of the crystal has been recorded and the various planes of reflections are identified. The XRD studies confirm the crystalline nature of the complex. The chemical composition of LLO was determined by carbon, hydrogen and nitrogen (CHN) analysis. The qualitative analysis on the crystal has been carried by using Fourier Transform Infrared (FTIR) spectral measurements. The presence of hydrogen and carbon in the grown crystal was confirmed by using proton and carbon nuclear magnetic resonance (NMR) spectral analyses. Optical behavior of the crystal was studied using UV – Visible spectroscopy. The mechanical strength of the grown crystals was found by using Vickers micro hardness test. The dielectric behavior of the crystal was determined at room temperature in the frequency range of 70 Hz to 5 MHz. The thermal stability and decomposition of the crystal were studied by thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC). The nonlinear optical property of the crystal was tested by Nd:YAG laser source.

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.
