Summary: Blood purification is an important field in biomedical engineering and medicine, with hemoperfusion being an effective method to physically separate impurities from the blood. Traditional adsorbents used in hemoperfusion have limitations, but the emergence of ordered porous materials (OPMs) has shown promise in overcoming these limitations. OPMs have unique properties, such as adjustable pore structures and high specific surface area, which make them ideal candidates for blood purification. This review discusses the synthesis, properties, and applications of OPMs in hemoperfusion, highlighting their potential for future clinical use.

Summary: Pore-selective silver-functionalized honeycomb-patterned polystyrene films were fabricated using a modified breath figure method. The antibacterial activity of the functional film was achieved by creating micro-trapping pits through the selective coating of silver in the pores. The film showed good antibacterial activity against Escherichia coli and Staphylococcus aureus. Furthermore, this method could potentially be used to selectively functionalize other metals or inorganic materials, providing diverse applications for honeycomb-patterned films.

Summary: The objective of this study was to determine the most representative methods of measuring air-water interfacial area for the retention and transport of PFAS and other interfacially active solutes in unsaturated porous media. Comparing multiple measurement and prediction methods, it was found that all methods produced coincident results for the interfacial area of glass beads, validating the aqueous interfacial tracer-test methods. The differences in interfacial areas measured for sands and soil were shown to be due to method-dependent contributions of solid-surface roughness.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
