Summary: TiO2 and CdS were synthesized and characterized in this study, and used to fabricate photoanodes for the degradation of naproxen in aqueous matrices. CdS with a low energy band gap was found to increase the photocurrent generated in the photoanode. The proposed photoanode showed efficiency for the photoelectrochemical degradation of naproxen with a kinetic constant of k = 1.1 x 10(-2) min(-1) and half-life of t(1/2) = 62.2 min(-1).

Summary: A C/CdS/TiO2 composite was prepared through a calcination method using sodium alginate as a medium. The carbon-based materials acted as a bridge connecting CdS and TiO2, promoting the efficient absorption of UV light and the construction of Z-scheme heterojunctions. The photocatalytic decolorization rate of cationic yellow X-GL in aqueous solutions by the composite was significantly higher than that of TiO2 due to the synergistic effect of hierarchical structure and the separation efficiency of photogenerated carriers.

Summary: A series of composite CdS/TiO2 powders were synthesized by nucleating TiO2 on CdS nanoseeds. This composite exhibited the appropriate band edge position for photocatalytic redox reactions: visible light irradiation of CdS facilitated electron injection into TiO2, thereby extending charge lifetimes. The obtained electrons were utilized for the efficient photoreduction of 4-nitrobenzaldehyde to 4-aminobenzaldehyde, as confirmed by H-1 NMR and ESI-MS positive ion mode. Simultaneously, sacrificial oxidation of 2-propanol occurred, serving as the proton source. Characterization techniques highlighted the crucial factors driving the photocatalytic reaction, including the nanoscale anatase crystalline domains, the presence of dispersed CdS forming an extended active junction CdS/anatase, and the presence of mesopores as nanoreactors. This system not only exhibited high photocatalytic activity using visible light but also demonstrated improved stability and recyclability due to the combination of TiO2 and CdS.

Summary: This study constructed highly ordered titanium dioxide nanotube arrays (TNTs) by changing the tissue structure of the titanium substrate, and investigated the influence of the titanium substrate structure on the growth morphology of nanotubes. The results showed that after rolling, there were a large number of dislocations and microscopic internal stresses in the grain structure of the titanium substrate, which improved the corrosion resistance of the materials. The changes in the microstructure of these materials made the nanotube arrays have highly ordered structure and better photoelectrochemical properties, providing a new idea for improving their applications in photoelectrochemistry.

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.

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.
