Summary: The influence of Mo content on the structural, tribo-logical, and mechanical properties of TiN films is investigated in this study. It is found that adding 18% Mo enhances the mechanical properties of TiMoN films, resulting in a high hardness of 28 GPa and lower friction coefficient compared to binary TiN films. The multi-phase strengthening and higher (H/E, H3/E2) values contribute to the improved mechanical properties and wear resistance of TiN films by alloying with Mo.

Summary: Systematic investigation was conducted on ultrathin (AlxGa1-x)(2)O-3/Al2O3 films with higher Al content prepared by magnetron sputtering method. The films showed improved crystalline quality with higher sputtering power, and increasing Al content led to a shift in Fermi level towards the valence band and an increase in work function. However, the higher Al content also suggested the possibility of a large number of defects or vacancies.

Summary: Rational design of heterostructures is an effective strategy for enhancing the photocatalytic activity of semiconductors. In this study, a dual Z-scheme CdS/ZWO/ZnS heterojunction photocatalyst was synthesized by assembling zero-dimensional CdS and ZnS quantum dots onto one-dimensional ZnWO4 nanorods. The photocatalytic experiments demonstrated that the dual Z-scheme heterojunction photocatalyst exhibited significantly higher photodegradation activity compared to individual CdS, ZnS, and binary CdS/ZWO and ZnS/ZWO heterojunctions. The characteristics and photocatalytic mechanism of the CdS/ZWO/ZnS photocatalysts were investigated using various measurement techniques and computational calculations.

Summary: A new type of Ag2MoO4/ZnWO4 composite photocatalyst with a Z-scheme mechanism was developed by anchoring AMO nanoparticles onto ZWO nanorods. The performances and photocatalytic mechanism of the AMO/ZWO heterojunctions were studied through multiple characterization methods and DFT calculations. The enhanced photocatalytic mechanism of the AMO/ZWO heterojunctions was revealed to be the efficient separation of photocarriers via a Z-scheme transfer process, which was confirmed by simulated-sunlight-driven photodegradation experiments and DFT calculations.

Summary: AuAg alloy nanoparticles were decorated on delta-Bi2O3 surface to obtain AuAg@delta-Bi2O3, and then AuAg@delta-Bi2O3 were hydrothermally combined with BiOBr plate to form Z-scheme AuAg@delta-Bi2O3/BiOBr. The photocatalytic activity of samples was evaluated under simulated sunlight irradiation, and the addition of delta-Bi2O3 significantly enhanced the photocatalytic activity of BiOBr. The introduction of AuAg nanoparticles further improved the photocatalytic activity, leading to highly efficient removal of pollutants. The presence of AuAg alloy nanoparticles at the interface of Z-scheme delta-Bi2O3/BiOBr promoted the separation of photogenerated charges through a Z-scheme charge migration mechanism.

Summary: A polyacrylamide gel method combined with low temperature sintering technology was used to fabricate BaTiO3/gamma-Al2O3 composite photocatalysts with excellent photocatalytic activity for the degradation of tetracycline hydrochloride under simulated sunlight. The effects of BaTiO3/ gamma-Al2O3 mass percentages, drug concentrations and pH values on photocatalytic activity were investigated. The optimum conditions were found to be 5 wt% BaTiO3/ gamma-Al2O3, 50 mg/L drug concentration, and pH 6.77. The enhanced photocatalytic activity of BaTiO3/ gamma-Al2O3 was attributed to the defect states in alumina, interfacial defects between barium titanate and alumina, and the type II band arrangement structure.

Summary: To improve optical fiber sensing performance and broaden its application, a photonic crystal fiber (PCF) plasmonic sensor with a U-shaped channel based on surface plasmon resonance (SPR) is proposed in this study. The influence rules of structural parameters, such as the radius of the air hole, the thickness of the gold film, and the number of U-shaped channels, were investigated using COMSOL and the finite element method. The dispersion curves, loss spectrum, and electric field intensity distribution were studied under various conditions. The proposed sensor achieved a maximum refractive index sensitivity of 24.1 mu m RIU-1 in the RI range of 1.38-1.43, with a FWHM of 10.0 nm, a FOM of 2410 RIU-1, and a resolution of 4.15 x 10(-6) RIU. The sensor combines the highly sensitive SPR effect and allows for real-time detection of the external environment. The detection range and sensitivity can be increased by adjusting the structural parameters. The sensor has a simple structure and excellent performance, providing a new approach for real-time detection and highly integrated sensing.

Summary: In this study, novel 13-Bi2O3/BiFeO3 heterojunctions were designed to enhance the piezo-photocatalytic activity for tetracycline hydrochloride (TC) elimination. The results showed that the optimal composite 9.1 %BO/BFO had a photodegradation activity 5.2 times higher than that of BiFeO3 and 1.9 times higher than that of 13-Bi2O3, which can be explained by the heterojunction-interface-field-induced Z-scheme photocarrier transfer mechanism. The piezo-photodegradation activity of the 9.1 %BO/BFO composite was further increased under both simulated sunlight and ultrasonic irradiation, demonstrating a synergistic enhancement between photocatalysis and piezocatalysis.

Summary: In this research, a tunable broadband absorber based on a layered resonant structure was designed, which achieved high absorption (more than 0.9) in the frequency range of 18-28 THz. The high absorption was attributed to strong resonance absorption between the layers and the resonance of the localised surface plasmon. The absorber, consisting of three layers of Dirac semimetal and three layers of optical crystal plates on a gold substrate, also showed tunability and absorption stability.

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.
