Summary: This review article focuses on supercapacitor electrode materials based on composites of metal-organic frameworks (MOFs) and conductive polymers (CPs). The combination of MOFs and CPs is an effective strategy to enhance the electrochemical performance of electrode materials. MOFs have unique properties such as high porosity and large surface area, but their low electrical conductivity limits their energy storage applications. CPs, on the other hand, have controllable conductivity and mechanical properties, making them attractive for supercapacitor applications. The review discusses hybridization strategies and provides a summary of recent advances in MOF@CP hybrids.

Summary: Anthropogenic activities release radioactive materials into the environment, posing serious health concerns. Limited research has been conducted on the occurrence, sources, distribution, and remedial solutions for radioactive contamination. Reports show higher concentrations of radionuclides in rivers and potable water than allowed levels, especially in parts of Europe and Asia. Adsorption is the common method for decontaminating polluted sites, but integrated approaches need to be investigated. Future research should focus on cost-effectiveness, waste minimization, sustainability, and rapid decontamination. Proper infrastructure is crucial for harnessing radioactive materials for nuclear power generation and preventing catastrophic disasters.

Summary: This study reviews the sequestration of aromatic organoarsenic compounds (AOCs) from aqueous media through adsorption. It discusses key components related to AOCs' adsorption, such as adsorbent performance, mechanism, isotherm, kinetics, and thermodynamics. The highest reported adsorption capacities for different AOCs were determined, as well as the dominant adsorption mechanisms. The Langmuir or Freundlich isotherm models were found to be the best-fit for describing adsorption equilibrium, and the pseudo-second-order model for kinetics. Thermodynamic studies showed that AOCs' uptake is generally spontaneous, suggesting the potential for industrial-scale removal. Future work should focus on using column systems for adsorption and proper disposal or recycling of used adsorbents.
