In the present work, Copper cobaltites (CuCo 2 O 4 ) were efficiently developed by the CTAB-assisted sonochemical process succeeded by calcination at 350 °C for 3 h. The differential scanning calorimetric analysis results showed that all the reactions ended at 300 °C. The Fourier transform infrared spectroscopy and X-ray diffraction results established the formation of spinel CuCo 2 O 4 /CuO. The morphological analytic results exposed that CuCo 2 O 4 possesses both the nanorods and nanoparticles structure. Furthermore, cyclic voltammetry (CV) and chronopotentiometric (CP) methods were used to evaluate the electrochemical properties of various CuCo 2 O 4 formed. It is observed that the freshly prepared CuCo 2 O 4 electrodes exhibit a very high specific capacitance of 811 Fg -1 at a scan rate of 5 mV s -1 and also demonstrates superior cycling stability retaining 91% of the initial capacitance even after 3000 continuous CV cycles. Hence, typical CuCo 2 O 4 could be considered as an important electrode material for supercapacitor applications.

In our efforts to propose, Praseodymium (III) metal complex derived from 5-Bromo-2-hydroxybenzyl-2-furyl methyl for the biological efficacy. The structure of the synthesized imine and complex has been characterized by UV, IR, Mass, 1 H and 13 C NMR. The ligand and the metal complex carried for their anti-microbial tendency to control the disease-causing pathogens such as Escherichia coli, Klebsiella pneumonia, Salmonella typhimurium, Acinetobacter baumannii, Pseudomonas aeruginosa and Staphylococcus aureus. The derived metal complex exhibited better result and is additional effective bactericides than the ligand.

This work described the synthesis and characterization of 1-(furan-2-yl) methanamine condensed with 5-bromo-2-hydroxybenzaldehyde Schiff base rare earth metal (Ln3+, Pr3+, Nd3+, Sm3+ and Eu3+) complexes.. They were characterized using relevant spectral techniques and docked against microbial target proteins (1H9Z, 3ZBO) theoretically. The experimental antibacterial and anticancer activities (HeLa, MCF7) of these metal complexes were investigated for biological efficacy. Out of five metal complexes, Pr3+ complex exposed good biological efficacy result in both assays.
