Summary: The use of new photocathodic protection technology to protect 304 stainless steel has attracted significant attention from corrosion researchers due to the severe consequences of metal corrosion on resources and economy. However, the photocatalytic materials used for protection still have some defects, such as high recombination rates and inefficient transfer of photoinduced electrons. In this study, PbS quantum dots modified TiO2 nanotubes were successfully synthesized and showed improved photocurrent density and optical absorption compared to pure TiO2, providing effective photocathodic protection for stainless steel under visible light irradiation.

Summary: Flower-like and bulk-like Co(OH)(2)-modified TiO2 p-n heterojunctions were successfully fabricated by a solvothermal method. The flower-like Co(OH)(2) microsphere-modified TiO2 showed better photoelectrochemical performance with narrower bandgap, upwardly shifted conduction band, and faster separation and migration of interfacial carriers compared to bulk-like Co(OH)(2). Additionally, the flower-like Co(OH)(2) microsphere-modified TiO2 photoelectrode exhibited effective photo cathodic protection for 304 stainless steel with a low photogenerated potential.

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.

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.
