Summary: The study investigates the effects of Cr and N doping on the properties of TiO2 anatase nanoparticles, including adsorption capacity, photocatalytic performance, and antibacterial response. Doping with Cr and Cr/N enhances adsorption capacity and photocatalytic performance, with Cr-TiO2 nanoparticles exhibiting antibacterial activity under visible light. The differences in electrostatic charge and nanoparticle dispersion are suggested as the main reasons for the varied antibacterial response among the doped nanoparticles.

Summary: Fe3+-doped anatase TiO2 hollow spheres were prepared using carbon sphere templates, and the effects of Fe content on their properties were investigated. The results showed that the crystallinity and crystal sizes of the samples decreased with increasing Fe dopant levels, and the defect states of Fe4+, Fe3+, Fe2+, and oxygen vacancies directly influenced the optical behavior, electrical conductivity, and photocatalytic activity of the Fe:THs. The hollow spheres with an Fe doping level of 0.25 mol% exhibited the highest photodegradation efficiency under visible-light irradiation, attributed to their large surface area and high pore volume.

Summary: Cu and Y co-doped TiO2 nanoparticles were prepared using an acid-catalytic sol-gel process, resulting in a single anatase phase with reduced crystallite size. SEM observations showed uniform nanospheres being synthesized under the proposed conditions. XPS results demonstrated the presence of Cu+ and Y3+ ions. The photoactivity of the co-doped TiO2 was improved due to effective separation of electron-hole pairs, increased formation of active radicals, and increased surface area.

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.
