Summary: In this study, interfacial segregation was explored as a strategy to enhance the electrical conductivity of Cl--doped ZnO. Cl-anions were found to segregate at the surface and grain boundaries, leading to a significant reduction in electrical resistivity. The calculated electric potential barrier height and activation energy for conduction also decreased with Cl-doping.

Summary: The abuse of antibiotics leads to antibiotic residues in aquatic environments, causing environmental pollution. In this study, a light-driven nanomotor system was developed that efficiently degrades antibiotics. The nanomotors removed a significant amount of antibiotics in a short period of time and displayed stable catalytic activity.

Summary: Inspired by capacitors, well-defined CuInSe2/N-doped carbon (CISe/N-C) nanorod arrays are synthesized to regulate charge migration and separation. The optimized CISe/N-C photoanode achieves a higher photocurrent (4.28 mA cm(-2)) compared to CuInSe2 photoanode (0.51 mA cm(-2)) due to the strong interfacial coupling between CISe and N-doped carbon. The interfacial coupling effects on carrier transfer dynamics are investigated by Kelvin probe force microscopy analysis and density functional theory calculation. This work provides new insights into improving the performance of photoanodes for PEC water splitting.

Summary: Metal oxide nanoparticle-reinforced polymers have attracted attention for their superior mechanical properties. This study investigated the effect of nanoscale reinforcements on polymer composites and found that a composite with 5 wt% ZnO nanorods exhibited improved elastic modulus, stiffness, and hardness. The viscoelastic response of the composite also showed enhanced performance to high impacts. However, the composites were still vulnerable to hypervelocity impact, although those reinforced with ZnO nanorods exhibited a cellular-like matrix with shock-induced voids.

Summary: The study shows that the ZnO/Au/ZnO sample with Au as the intermediate layer has the highest transmittance in the visible region (68.95%) and the highest Figure of Merit (5.1 x 10(-4) omega(-1)). Therefore, it can be considered as relatively the optimal sample for energy-saving building windows due to its low U-value (2.16 W/cm(2) K) and low emissivity (0.45).

Summary: Organic materials can modify the optical properties of layered (2D) hybrid perovskites, and their effects on photophysics are often overlooked. In this study, the impact of spacer size and perovskite phase configuration on charge transfer excitons in 2D perovskites is investigated using transient absorption spectroscopy and electroabsorption spectroscopy. It is found that charge transfer excitons form in the Dion-Jacobson (DJ) phase, leading to a photoinduced Stark effect dependent on the spacer size. Moreover, temperature-dependent measurements reveal new features in the transient spectra of the Ruddlesden-Popper (RP) phase at low temperatures due to the quantum-confined Stark effect.

Summary: The abuse of antibiotics and the resulting antimicrobial resistance have made the development of new antibacterial materials an urgent and significant issue. In this study, a hybrid ZnO@Au nanorod array was reported, which showed fast bacterial inactivation and excellent recyclability. The antibacterial mechanism involves the generation of reactive oxygen species (ROS) from photocatalysis and piezoelectricity, electron transfer (ET) from bacteria to nanorod array, and mechanical effects from the nanorod. The study demonstrates the potential of hybrid structures in antibacterial applications and provides insights into the design of next-generation antibacterial materials.

Summary: This study compares the performance of Au/n-Si Schottky diodes/contacts (SDs) with different interfacial layers and finds that the structures with hydrothermally synthesized ZnO-PVP and ZnO/Ag2WO4-PVP interfacial layers outperform traditional metal-semiconductor Schottky diodes due to their ability to control barrier height, surface passivation, and leakage current reduction. The rectification ratio of the Au/(ZnO/Ag2WO4-PVP)/n-Si SD is significantly higher than that of the other structures, and the ideality factor and zero-bias barrier height are found to be the lowest for this structure. The ZnO-PVP and ZnO/Ag2WO4-PVP interfacial layers effectively prevent Au and n-Si from reacting or diffusing with each other and passivate the dangling bonds at the Si surface.
