ZnO finds a wide variety of applications and is one of the most studied wide band gaps (~3.2eV at room temperature) material. ZnO exhibits interesting electrical, optical and chemical properties. Here structural and optical property of the as-synthesized nanoparticle were characterized by XRD and UV- Visible spectroscopy X-Ray Diffraction technique was used to identify the crystalline structure, phase purity and crystallite size of the as-prepared Zno nanostructures. It was observed that ZnO nano powders are highly crystalline and single phase with hexagonal structure. UV-Visible absorption studies reveal the Optical characterisation of the as-prepared ZnO nanostructures were conducted using JASCO V760 Spectrophotometer. Direct bandgap of the ZnO nanostructures is obtained by this study. Bandgap of the samples were found to be 3.18eV. Antibacterial studies showed that green synthesised grown ZnO nanostructures can be used effectively for the destruction of human pathogens Kpneumonia and Shigella 2022-05-01T00:00:00Z https://digitallibrary.bishopmoorecollege.ac.in/xmlui/handle/123456789/1685 “IN VITRO LIPOLYTIC ASSAY OF THE PHENOLIC AND FLAVONOID EXTRACTS OFCurcuma longa L.

India is one among the megadiverse countries, of which western ghats and Srilanka are regarded as one of the hotspot of the total 34 global hotspots. Since some species exhibit large complexities, in an overall view this plant group is facing the threat of vulnarability and extinction. In this condition a floristic assessment is necessary to determine the present status of plant distribution. The Present work is on the diversity and taxonomy pteridophytes of Thazhava panchayath of kollam district. About 26 species of pteridophytes were collected from the study area; which comes under 10 families. In which pteridaceae is the largest family with 6 genus and 10 species. Among the collected species most species are included in least concern category; Salvinia molesta included in Invasive Species Specialist Group and Pteris perrottetii is endemic to south India according to IUCN. 2022-05-01T00:00:00Z
