Summary: This study compares the effects of two synthesis methods, Chemical Vapor Deposition (CVD) and Ultrasonic Nebulized Spray Pyrolysis of Aqueous Combustion Mixture (UNSPACM), on the Semiconductor-Metal Transition (SMT) characteristics of VO2 thin films. The SMT characteristics of the films were measured electrically and optically. The CVD films showed lower resistance ratio and SMT strength, while the films synthesized via UNSPACM had rougher surfaces. The observed behavior is attributed to morphology and off-stoichiometry resulting from the deposition process.

Summary: In this study, we demonstrate theoretically and experimentally a strong and tunable optical anisotropy in epitaxially-grown VO2 thin films. We reveal that these films exhibit an ultra-large birefringence through a combination of temperature-dependent X-ray diffraction, spectroscopic ellipsometry measurements, and first-principle calculations. Moreover, by leveraging the insulator-to-metal transition of VO2, we demonstrate a dynamic reconfiguration of optical properties from birefringent to hyperbolic, opening avenues for multi-functional devices with tunable anisotropy and hyperbolic dispersion.

Summary: In this study, Ti-doped CsXWO3 (Ti-CsxWO3) nanopowders were synthesized through a solvothermal reaction and post-annealing to improve the optical properties of CsxWO3. The 1.71 at. % Ti dopants significantly enhanced the visible transmittance and near-infrared shielding efficiency of CsxWO3. The Tlum and Psi NIR of the 1.71 at. % Ti-CsxWO3 polymer film were 63.87% and 76.90% respectively, which were 51.88% and 65.00% higher than those of the CsxWO3 film. Ti doping induced the broadening of the band gap and smaller size of the nanoparticles, leading to the improvement of Tlum, while the increased free electron concentration and energy levels of impurities resulted in the enhanced Psi NIR. The incorporation of Ti elements makes CsxWO3 a promising material for energy-saving applications.

Summary: The Z-scheme heterojunction is promising in photocatalysis due to its efficient carrier separation and strong photoredox properties. However, regulating charge separation at the nanometric interface remains a challenge. In this study, we used g-C3N4 and MoS2 as models and designed the Mo-N chemical bond to connect the CB of MoS2 and VB of g-C3N4. The Mo-N bond acts as an atomic-level interfacial bridge, facilitating charge carrier migration between g-C3N4 and MoS2. Experiments confirmed that the Mo-N bond and internal electric field greatly enhance photogenerated carrier separation. The optimized photocatalyst exhibits a hydrogen evolution rate 19.6 times higher than pristine bulk C3N4. This study demonstrates the importance of atomic-level interfacial chemical bond design in heterojunctions and provides a new approach for efficient catalytic heterojunction design.

Summary: The microwave-driven strategy for actuators has advantages of selective energization, uniform heating, and high penetration depth. Understanding the microwave stimulus-response mechanisms is crucial for developing universal construction strategies. The study focuses on implanting reduced graphene oxide (rGO) into liquid crystal elastomer (LCE) to construct soft and sensitive microwave actuators. The LCE-rGO composites demonstrate excellent polarization relaxation-dominated dielectric loss and electromagnetic energy conversion ability. Additionally, the implantation of rGO lowers the actuation threshold and shortens the response time of LCE-rGO.

Summary: The band structure of a heterojunction greatly affects the efficiency of photocharge separation. Designing heterojunctions with appropriate band structures is crucial for photocatalytic applications. In this study, we demonstrate that the ferroelectric polarization in a Bi5Ti3FeO15/BiOCl heterostructure can change the direction of photocharge flow, overcoming the energy barrier limitations of a type-I heterojunction. The results show that the polarized BTF/BOC films exhibit a photocurrent density three times larger than the unpolarized films, which is attributed to the large-area and semi-coherent interface of the BTF/BOC heterojunction.
