Summary: Recent research has focused on finding new electrode materials to improve the specific capacitance of supercapacitors. Conductive polymers and metal oxides have been extensively tested as electrode materials and their composite shows excellent electrochemical performance for supercapacitors. In this study, nanoscale alpha-NiMoO4 particles were fabricated on electronically conducting polymer nanocomposites based on Polyvinyl alcohol (PVA)/Poly(vinyl) pyrrolidone (PVP) for supercapacitor applications. The prepared nanocomposites exhibit non-uniform rod-like structure and show high specific capacitance and columbic efficiency, indicating their potential as portable and flexible electrodes for energy storage applications.

Summary: Molecularly Imprinted Polymers (MIPs) modified screen-printed carbon electrode (SPCE) was developed for the determination of p-aminophenol (p-AP). The MIP was prepared using p-AP as a template, chitosan as a base polymer, and glutaraldehyde and sodium tripolyphosphate as crosslinkers. The results showed that the MIP selectively accumulated analytes on the electrode surface, and MIP with glutaraldehyde as a crosslinker increased the signal.

Summary: The study investigates the distribution of Geobacter spp. and their electrochemical performance within exemplary fixed-bed electrodes. Results show that approximately 10% of the bed volume, specifically near the current collector, achieves the majority of electroactivity. Despite Geobacter spp. dominating all sampled granules, engineered bed electrodes are needed to improve electron exchange between microorganisms and granules.
