Advanced oxidation process (AOP) is a recently developed by the researchers for the wastewater treatment over a decade which has more advantages when compared with other conventional methods. Photocatalysis is the most efficient and attractive techniques for the degradation of organic pollutant using semiconductor nanostructured material in presence of solar energy. The researchers decided on the rising deprivation rate of pollutants by incorporating inorganic materials into conducting polymers to understand its synergistic and complementary behaviour among the polymer and inorganic materials. Based on this, the present study is to synthesize polymeric nanocomposite material ZnO with polyazomethine (PNZ) and TiO2 with polyazomethine (PNT) through ultrasonication technique. The synthesized polymeric nanocomposites were used for the photodegradation of cationic and anionic dyes. These synthesized polymeric nanocomposites can act as a potential alternate in future due to its enhanced dye degradation ability and higher stability nature. By varying pH of the dye solution at different time interval the degradation efficiency of photocalatystswere analyzed and found that cationic dyes are removed more when compared to anionic dyes.

The present study was elucidating the cardioprotective activity of hydroethanoic extract of Zanthoxylum armatum (Z. armatum) fruit on serum cardiac markers, lipid profile and the level of antioxidants in experimentally induced myocardial infarction (MI). The hydroethanolic extract of Z. armatum fruit was administered at a dose of 200 and 400 mg/kg body weight for 30 days to male Wistar albino rats. On 28th and 29th day, isoproterenol (ISO) (8.5mg/100g body weight) wasadministered to induce MI. Animals were sacrificed; blood and heart tissues were removed and the biochemical parameters were carried out. Serum markers such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB) and troponin –T were significantly (p<0.05) increased after ISO treatment. Altered lipid profile and significant changes in enzymic and non- enzymic antioxidants were also observed in MI. The altered levels were brought back to near normal by the administration of hydroethanoic extract of Z. armatum fruit which might be due to the active phytoconstituents present in it.
