Summary: Mixed matrix membranes (MMMs) combining polymeric and inorganic materials have emerged as a promising membrane material, offering dimensional stability, efficient gas separation ability, facile fabrication, and low cost. Zeolite imidazolate frameworks (ZIFs) show good compatibility with polymers and beneficial properties, making them widely incorporated into polymer matrix for MMM fabrication. Modification techniques of ZIFs are discussed to enhance gas separation performance of MMMs, revealing potential to alter membrane structure and overcome trade-off effects.

Summary: Dihydromyricetin (DHM) holds potential as an antitumor agent, but its low bioavailability limits its clinical application. In this study, DHM@ZIF-8 nanoparticles were developed using ZIF-8 as a carrier to enhance its antitumor activity. The nanoparticles exhibited a regular morphology with a suitable particle size and a high drug release rate in a simulated tumor micro acid environment. Compared to the prodrug, DHM@ZIF-8 showed increased killing effect on HepG2 cells, along with enhanced removal of ROS, promotion of apoptosis, and significant modulation of apoptosis-related proteins within tumor cells.

Summary: The aim of this study was to investigate CO2 adsorption on the highly porous ZIF-8. Characterization of ZIF-8 was done through techniques such as X-ray diffraction, scanning electron microscopy, TGA analysis, and N2 adsorption-desorption isotherms. Adsorption isotherms were obtained at different temperatures (273 K, 298 K, 323 K, and 353 K). A new model based on multilayer with saturation was simulated and interpreted. Physicochemical parameters describing the CO2 adsorption process and thermodynamic functions governing the adsorption process were determined. The results showed that CO2 adsorption on ZIF-8 was spontaneous and exothermic.

Summary: This study reports a self-adjusting metal-organic framework based on multiple weak binding interactions for capturing trace amounts of xenon and krypton from nuclear reprocessing off-gas. The self-adjusting behavior of ATC-Cu and its mechanism have been visualized and studied. The results show that ATC-Cu exhibits unprecedented high uptake capacities and record xenon capture capability from the nuclear reprocessing off-gas. This work not only provides a benchmark xenon adsorbent, but also proposes a new route for constructing smart materials for efficient separations.

Summary: In this study, a Pt-Al-Ce catalyst was prepared and applied in the photo-thermo-chemical dry reforming of methane (DRM) driven by concentrated solar irradiation. It was found that the Pt-Al-Ce catalyst showed good stability and significantly enhanced H-2 and CO production rates compared to other catalysts. Light irradiation induced photocatalytic activities on Pt-Al-Ce and reduced the reaction activation energy.

Summary: Metal-organic frameworks (MOFs) are promising materials for energy storage due to their large specific surface area and defined porosity. However, their utilization in supercapacitors has been hindered by poor conductivity. Recently, 2D conductive MOFs have emerged, and an anodic electrodeposition (AED) approach has been developed to fabricate uniformly deposited 2D conducting MOFs on nickel foam, which can be directly used as electrodes for supercapacitors without any additives. Electrochemical measurements have demonstrated the superior performance of these 2D conducting MOFs in both aqueous and organic electrolytes, highlighting the advantages of the AED approach over traditional methods.

Summary: The operation of a molten salt reactor requires the circulation of a cover gas to remove radioactive gases and maintain an inert atmosphere. This study developed a metal organic framework (MOF) for the capture of xenon (Xe), a major component of the off-gas. The MOF was tested using a laser-induced breakdown spectroscopy (LIBS) sensor to monitor noble gases, and the study demonstrated the feasibility of using LIBS sensors to aid in the development of new capture systems for molten salt reactors.

Summary: We demonstrated enhanced ion transport properties of a type-II porous liquid electrolyte that utilizes crown ethers to coordinate and transport Li+ and Mg2+ ions. The 12-crown-4-based electrolyte showed the highest ionic conductivity due to the size match between the crown ether cavity and Li+ ion. Molecular simulations provided detailed insights into the solvation environment and complexation between the ions and crown ethers.
