Summary: This study confirmed the significant synergistic effect in the photocatalytic ozonation process for less adsorbed organic pollutants, while catalytic ozonation showed faster kinetics due to the higher exposed surface area of TiO2 agglomerates. The high BET surface area of the photocatalyst is crucial for fast surface reactions, while good dispersion and charge separation play important roles in the degradation of less adsorbed pollutants.

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: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
