Growth, XRD, Spectroscopic, Hardness and SHG studies of L-asparagine monohydrate single crystals

ABSTRACT Single crystals of L-asparagine monohydrate (LAM) have been grown by slow evaporation solution growth technique. Single crystal X-ray diffraction analysis was employed to identify the cell parameters. The reflection planes of LAM crystal were confirmed by the powder X-ray diffraction study and diffraction peaks were indexed. Functional groups of the sample were identified by FTIR analysis. Optical properties such as optical transmittance and second harmonic generation were also studied on the grown LAM crystals. The soft nature of LAM crystal was checked by measuring the microhardness test

Oxalic acid incorporated acetamide single crystal growth dynamics, characterization, NLO and antimicrobial activities via shock wave treatment

Shock waves are applied to non-linear optical materials, particularly organic materials, due to their fast response in electro-optic switches and high nonlinear efficiency. At room temperature, an acetamide-doped oxalic acid single crystal has been grown using the slow evaporation method among other crystal growth techniques. Single crystal oxac applies to shock waves in steps of 50 and 100 shock waves to the tail or the material properties without altering the original crystal system. The grown and shock wave treated crystals of OXAC were structurally identified by X-ray diffraction and Fourier transform infrared spectroscopy,UV–Visible and Photoluminescence spectral analysis, nonlinear optical activity (NLO) studies. The antimicrobial studies such as antibacterial and antifungal activities of the grown crystals of oxalic acid, OXAC and OXAC with 50 and 100 shocks were performed and the obtained results were discussed. From we declared results, we state that the post shock wave induced OXAC crystal is enhancing properties of NLO, antimicroibial studies relatively pre shock wave induced OXAC crystal and reflected in structural and optical studies
