Synthesis, structural, mechanical, thermal, magnetic and antimicrobial properties of β-L -Glutamic acid

Abstract

β - L - Glutamic acid a semiorganic single crystal and grown by slow evaporation technique at room temperature. The lattice parameters of the grown single crystals were determined by using single crystal X – ray diffraction analysis and it reveals that the crystal lattice system is orthorhombic. Powder X- ray diffraction confirms the crystalline nature and the diffraction planes were indexed. The mechanical strength of the grown crystal was estimated using Vickers microhardness tester. The dielectric response of the grown crystal was analyzed at different temperatures in the frequency range from 50 Hz to 2 MHz. Thermal properties were investigated by thermogravimetric, differential thermal and differential scanning calorimetric analyses. Antibacterial and antifungal studies were carried out against ACDP declared harmful pathogens. The surface features of the grown crystal were analyzed using scanning electron microscopy analysis. The magnetic property was studied with the help of vibrating sample magnetometer.
