Summary: This study aims to investigate the correlation between the structural properties of different TiO2 catalysts and their photocatalytic performance and selectivity in CO2 reduction at different pH levels. Two types of TiO2 catalysts were prepared and extensively characterized using various techniques. The prepared catalysts exhibited higher selectivity in CO2 reduction compared to a commercial P25 catalyst. The TiSG catalyst, which had the lowest portion of hydroxyl oxygen species, showed the highest photoreduction efficiency. The study also explored the effect of pH on the efficiency and selectivity of photocatalytic CO2 reduction, revealing different product distributions in acidic and basic environments.

Summary: Based on the results, co-doping of Sn/Fe in TiO2 nanoparticles inhibited the crystallization transformation and decreased the energy band gap. The abnormal grain growth of the particles was observed due to the influence of calcination temperature and dopant. The co-doped nanoparticles with 0.6 at.% Sn/0.2 at.% Fe and 1.0 at.% Sn/1.0 at.% Fe showed better photocatalytic performance under visible light irradiation, while the nanoparticles co-doped with 0.2 at.% Sn and 0.6 at.% Fe and calcined at 650 degrees C exhibited the highest photocatalytic performance under UV light irradiation.

Summary: In this study, samarium titanate (Sm2Ti2O7) with increased porosity was synthesized using tetrabutylammonium hydroxide (TBAOH). The use of TBAOH significantly enhanced the porosity of the samples, resulting in improved photocatalytic performance. Sm2Ti2O7(1.0) exhibited the highest BET surface area and pore volume, and the lowest photoluminescence intensity, indicating the lowest recombination efficiency of electrons and holes. Degradation efficiency tests showed that Sm2Ti2O7(1.0) had the highest degradation efficiency and reusability.

Summary: In this study, MgO particles were synthesized via sol-gel technique and characterized under different heating rates. It was found that MgO powders had a high crystalline structure and surface morphologies did not change with heating rates. MgO particles produced at 2 degrees C/min heating rate showed better antibacterial performances, possibly due to surface oxygen vacancies and higher surface area.

Summary: The effect of different laser beam power on the nanoindentation and corrosion properties of Ti6Al-4V alloys fabricated by the DMLS method was investigated. It was found that as the laser beam power increased, the proportion of the b phase in the microstructure increased, while the reduced elastic modulus and hardness values decreased, indicating better anti-wear capacity and resistance to deformation. Additionally, Ti6Al-4V samples fabricated with low laser power showed better corrosion resistance.

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.
