Summary: The use of multi-pore nanostructured g-C3N4 photocatalysts can effectively separate photogenerated charge carriers and enhance visible light photocatalytic performance. In this study, a novel technique based on P407 bubble clusters templating and fixation by freezing was introduced to fabricate 3D opened-up macroporous g-C3N4 nanostructures for photocatalytic H2 evolution. The resulting hierarchical nanostructures provide more active sites and promote the creation of heterogeneous catalytic interfaces, leading to a remarkable visible light-induced H2 evolution rate.

Summary: Self-doped Ti3+-TiO2 and amorphous ZnS layers-coated Ti3+-TiO2 nanostructures were successfully synthesized for organic pollutant degradation under visible-light illumination. The Ti3+-TiO2 clusters exhibited efficient visible-light absorption and photocatalytic performance, while the amorphous ZnS layers greatly enhanced the charge separation between ZnS layers and self-doped Ti3+-TiO2 clusters. The Ti3+-TiO2@ZnS-15% heterojunction showed the highest photocatalytic activity, approximately 9.87 times that of commercial TiO2, and also exhibited enhanced performance in degrading ciprofloxacin and tetracycline under visible-light illumination.

Summary: SnO2:Bi3+ nanoparticles were synthesized by a one-step hydrothermal method. The influence of Bi3+ impurity concentrations on the size, morphology, and band gap width of SnO2:Bi3+ materials was deeply investigated. The interaction between the SnO2 crystalline host and Bi3+ was studied using characterization techniques such as SEM, XRD, UV-Vis, PL, and EPR. The photocatalytic activity of the SnO2:Bi3+ nanoparticles was higher than that of pure SnO2 nanoparticles. The high degradation efficiency of the SnO2:Bi3+-2% sample was attributed to its small crystal size and defect states, which increased the specific surface area and surface charge carrier transfer rate.

Summary: In this study, a high surface area nanoporous carbon derived from MOF-5 was used as a hard template for the synthesis of TiO2 nanoparticles by nanocasting. The interconnected mesoporous network of the carbon template led to the formation of brookite and anatase TiO2 with highly developed mesoporous and macroporous structures. Furthermore, the fabricated brookite and anatase showed enhanced photocatalytic efficiency in visible light due to increased light harvesting ability and reduced band gap energy.

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: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

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.

It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
