Summary: The study prepared CMO microspheres with porous core-shell structure and investigated their properties. As an electrode for capacitive deionization, the optimized AC || CMO device exhibited high salt removal capacity and current efficiency, with a relatively high capacity retention rate. It was found that the intercalation/de-intercalation of sodium ions in CMO were governed by the (103) and (221) crystal planes, which had higher adsorption energies for Na+.

Summary: Capacitive deionization is an emerging electrochemical technique for water desalination, with extensive research being conducted on architectures and materials to enhance electrosorption performance. Asymmetric architectures with faradaic materials are found to have superior performance compared to symmetric architectures. Faradaic materials also outperform carbon-based materials. Customization of architectures and materials allows for selectivity of target components and heavy metal removal. Factors such as synthesis procedures, additives, operational modes, and fouling can affect electrosorption performance. Further research is needed to fully understand and improve the performance of capacitive deionization.

Summary: Hydrothermal liquefaction is a promising technology for microalgae-based biofuel production, but its aqueous wastes containing toxic ammoniacal nitrogen have little established reuse. The use of microbial electrolysis cells to valorize this waste has shown efficient removal of organic compounds and ammoniacal nitrogen for hydrogen production. The effluent from microbial electrolysis cells can be reused to grow the same microalgal strains, creating a circular biofuel production system with potential for further development.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.
