Summary: Ionic covalent organic frameworks (COFs) with zwitterionic groups exhibit high SO2 adsorption capacity and impressive SO2/CO2 selectivity due to the separated cationic and anionic groups in their channels. The zwitterionic groups in COFs' channels can induce complete proton carrier deprotonation, leading to outstanding anhydrous proton conductivity. This work opens up possibilities for designing well-defined zwitterionic frameworks for gas separation and ion conduction.

Summary: This study proposes a promising synthetic method for functionalized titanium dioxide (TiO2) by combining photoactive porphyrin-periodic mesoporous organosilica (PMO) with hollow TiO2 nanospheres, forming a multi-component synergistic system. The prepared composite TiO2@Pro exhibits photocatalytic activity in the aerobic oxidation of sulfide in the aqueous phase under visible light. The high reactivity is attributed to the catalyst's large specific surface area, amphiphilicity, wide visible light absorption, and high electron-hole pair separation rate. This strategy provides a new approach for designing TiO2-based photocatalysts for heterogeneous catalysis under visible light.

Summary: The confinement of proton carrier molecules in nanostructures can reduce their proton dissociation energy. However, restricted molecular motion from surface attraction impedes the easy transportation of free protons. To address this issue, imidazole is confined in the channels of porous coordination polymers with tunable geometries, and its electric/structural relaxations are measured. Imidazole confined in square-shaped channels exhibits heterogeneity in dynamics with a core-shell-cylinder model. The dimensions and geometry of the nanochannels play a crucial role in shielding the blocking effect from attractive surfaces and facilitating the filling of internal proton carrier molecules, leading to enhanced dynamics and proton conductivity.

Summary: The solvothermal method improves the structural and chemical defects of crystal growth by adjusting the factors affecting its growth. This allows for the control of crystal morphology, size, and functionalization. The solvothermal method is cost-efficient for synthesizing micro/nano carbons (M/NCs) due to its low reaction temperature, environmental friendliness, and high yields. The review provides a brief history and process of solvothermal synthesis and summarizes the different methods and applications of M/NCs in various fields.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
