Summary: An interface-induced synthesis of FeNx-CNTs with high activity in ORR was achieved by coating PPy thin layers on Fe-ZIF. The polymer/MOF interface constructed suppressed Fe atomic site agglomeration and facilitated CNTs formation with FeNx coordination in the carbon matrix. The produced FeNx-CNTs catalyst exhibited excellent ORR activities with peak power densities of 1.15 and 1.16 W cm(-2) in anion and proton exchange membrane fuel cells.

Summary: With the rapid development of the economy, there is an urgent need for energy. Microbial fuel cells (MFCs) are considered to be the ideal choice for the next generation of energy storage equipment due to their non-toxic, safe, and environmentally friendly advantages. However, the slow kinetics of oxygen reduction reaction (ORR) on MFC air cathodes and the high cost of traditional platinum (Pt) catalysts hinder their practical application. Recent research has shown that metal-organic framework (MOFs) and carbon nanocomposites can provide efficient, low-cost, and stable electrocatalysts as alternatives.

Summary: Due to odd weather patterns and post-pandemic economic recovery, there has been an increase in global demand for oil, coal, and natural gas. However, the excessive usage of these fuels has led to depletion of their reserves and contributed to global warming and power shortage problems. In light of this, it is crucial to focus on and promote the use of renewable energy sources for power production and storage.

Summary: Electrocatalysis is crucial for achieving a sustainable energy economy by facilitating redox reactions for the generation of clean fuels and chemicals from various resources. The widespread implementation of electrocatalysts is hindered by the lack of readily available catalysts that are economically viable, long-lasting, and efficient. MXenes, a family of emerging 2D materials, exhibit exceptional properties as electrocatalysts in metal-air batteries due to their hydrophilicity, high electrical conductivities, and tunable surface properties.

Summary: To improve the safety of Li-ion batteries, understanding their behavior under high temperature is crucial. In this study, charge and discharge experiments were conducted on battery packs to evaluate the impact of thermal management on battery performance. By analyzing the temperature distribution among the cells under different conditions and using phase change material, it was found that thermal management significantly affects the battery pack's performance and safety. Active cooling (air cooling) and passive cooling (using PCM) were both effective methods to reduce the temperature difference compared to ambient temperature, with passive cooling showing the most promising results.

Summary: This study successfully prepared a composite material by carbonization of V-MIL-101, in which vanadium oxide nanoparticles and nanoporous carbon network were embedded, significantly improving the electrochemical performance of the material as a cathode in an aqueous Zn-ion battery system. The loading of manganese oxide further stabilized the composite material and improved the rate capability of the cathode material in the aqueous zinc ion battery. The MnO2@NVC composite cathode material exhibited a capacity of 299 mAh/g at a 0.1C rate for 100 cycles, benefiting from the synergistic effect of the high conductivity of vanadium oxide nanoparticles and the suitable voltage of MnO2. The materials showed superior capacity retention and better cycling performance compared to unmodified vanadium oxide nanoparticles on a carbon substrate as cathode material. Comparative morphological and electrochemical studies confirmed the improved performance, suggesting that the vanadium oxide nanoparticles anchored on a high surface area carbon network intertwined with manganese oxide nanowires provide enhanced conductivity.

Summary: The sensing of bio-molecules and toxic compounds has been a long-term interest. However, the similar reduction potential values and diverse chemical nature of these analytes make the simultaneous and accurate determination challenging. In this study, a transition metal oxide/graphitic-carbon nitride composite was successfully fabricated, which exhibited suitable band-gap formation and facilitated the reduction of dopamine and hydrazine at different potentials. The characterization of the composite material was conducted by SEM-EDX, XRD, FTIR, and electro-chemical analysis. The sensor response analysis revealed that the as-prepared material showed superior LOD for hydrazine compared to dopamine.

Summary: In this study, Cu-doped ZnS thin films with different doping concentrations were fabricated on glass substrates using the spin coating technique. Various characterization techniques including X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, and Fourier transform infrared spectroscopy were employed to analyze the thin films. The results showed that Cu-doped ZnS thin films had a single phase wurtzite structure, but the formation of secondary phases was observed in the 6% doped samples. Cu doping led to a decrease in the energy band gap of the thin films, which could be attributed to the existence of Cu-3d states in the upper part of the valence band.
