MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641019210 A) filed by Srm Institute Of Science And Technology; and Easwari Engineering College, Chennai, Tamil Nadu, on Feb. 19, for 'from lattice shock to multifunctional gain: urea-gallic acid molecular crystals.'
Inventor(s) include Dr. M. Saravanan; and M. Keerthana.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "Deliberate modification of a molecular crystal with an external stimulus is one of the most efficient ways to improve multilevel functions. Urea gallic acid (UGA) single crystals were prepared by slow evaporation and subsequently exposed to a Mach 1.3 shock wave during slow cooling to investigate their structural, optical, electronic, and biological properties. Shock waves generated from a laboratory-scale shock tube, where pressurized air bursting through paper diaphragms created high-pressure blasts. The crystals were exposed to shocks of 2.5 ms at 2-second intervals. Uv-Vis-Optical studies revealed improved optical transparency, a smoother absorption edge, and a slight bandgap widening after shock treatment, indicating reduced defect states and enhanced electronic order. The shocked crystals manifested a substantial increase in antibacterial and antifungal activities. Besides, Z-scan analysis revealed a significant enhancement in the third-order nonlinear optical parameters. In vitro experiments on HepG2 cancer cells resulted in anticancer activity augmentation. The results constitute an inaugural detailed account of UGA crystals impacted by shock waves. This work is the first to provide a full report on the antibacterial, antifungal, and anticancer properties of UGA single crystals.They empower structural, optical, and bioactive performance alteration in a single-step manner, thus, opening possibilities for nonlinear optical, photonic, and biomedical applications."
