Summary: In this study, low-surface-energy fluorinated silica nanoparticles were prepared using a combination of plasma and perfluorodecyltrimethoxysilane. These nanoparticles self-assembled on the surface of epoxy resin, resulting in a thin film structure. The self-assembly structure significantly improved the surface flashover voltage and hydrophobicity of the epoxy resin composites. The maximum surface flashover voltage increased by 35.73% to 12.08 kV, and the maximum water contact angle reached superhydrophobicity at 155.5 +/- 3 degrees. This study provides a promising approach for synergistically improving the flashover voltage and hydrophobicity of insulating materials.

Summary: Absorption losses and laser-induced damage threshold (LIDT) are the main limitations for the development of optical coatings for high-power laser optics. This study developed heterostructures using sub-nanometer thin films of SiO2 and HfO2 with the plasma-enhanced atomic layer deposition (PEALD) technique. Various thin-film characterization techniques were employed to extract optical constants, residual stress, layer formation, and functional groups of the heterostructures. The heterostructures showed tunable refractive index, bandgap, improved optical losses, and LIDT properties.

Summary: Lead halide perovskite nanocrystals have great potential for photoelectronic applications, but maximizing their stability remains a challenge. A novel surface functionalization method was developed, resulting in superhydrophobic SiO2-coated CsPbBr3 nanoparticle films with excellent water repellency, self-cleaning properties, and high stability. The luminescent films showed a 46% increase in photoluminescence intensity over 180 days, and CsPb2Br5-based luminescent films maintained 75% of their initial intensity after 10 days of water soaking. White-light-emitting diode devices using these nanoparticles achieved over 20% external quantum efficiency and maintained high stability even after 2 weeks.

Summary: Optically induced magnetic resonances (OMRs) are highly tunable scattering states that cannot be reproduced in systems that only support electric resonances. In this study, we synthesized OMR-based thin films composed of monodisperse crystalline silicon nanoparticles and investigated their absorption and scattering response. The results show that the thin films exhibit near complete blackbody absorption and strongly directional forward scattering, providing angle- and polarization-insensitive antireflection properties across the visible spectrum. A modified effective medium model considering multipole resonances and interparticle coupling is found to agree well with the experimental results.

Summary: Smart window glazing technology has great potential in reducing energy demand in buildings. Thin films based on VO2 are suitable for smart window applications, but optimization is still ongoing. Codoping VO2 with Sr and W brings the parameters close to the desired range, but full satisfaction of smart window requirements is not achieved. Embedding V1-x-ySrxWyO2 between optimized TiO2 layers adds degrees of freedom to meet all optical parameters and improves T-lum by approximately 10%.

Summary: Solar steam generation through hydrogel-based evaporators has shown great promise for freshwater production. However, developing hydrogel-based evaporators with stable performance in high-salinity brines remains challenging. In this study, phase-separated polyzwitterionic hydrogel-based evaporators with sponge-like structures were fabricated and shown to demonstrate stable water evaporation rates and high solar-to-vapor efficiency in high-salinity brines under simulated solar light irradiation. The polyzwitterionic hydrogel evaporators with sponge-like porous structures have potential applications in high-salinity seawater desalination.

Summary: Antimicrobial photodynamic therapy (PDT) is a promising strategy for eradicating biofilms, but its efficacy is hindered by the low solubility and poor penetration of photosensitizers (PSs) into the biofilms. This study develops a dissolving microneedle (DMN) patch composed of a supramolecular PS for enhanced biofilm penetration and eradication. The DMN patch can efficiently penetrate the biofilms, allowing for optimal photodynamic elimination of bacterial biofilms. In addition, the DMN patch shows good biosafety in vivo for eradicating Staphylococcus aureus biofilm infection.

Summary: Based on molecular dynamics (MD) simulation, the adsorption and absorption of shale oil in a type II kerogen slit were calculated, and the influences of temperature, pressure, and pore diameter on the occurrence of shale oil were discussed. The results showed that temperature had opposite effects on the distribution of shale oil in adsorption and absorption, while pressure and pore diameter had minimal influence. Under aqueous conditions, the absorption of shale oil was blocked once water clusters formed. The evolution of the ratio of free-adsorbed-absorbed oil at different temperatures and pressures was also established, providing a new method for detecting the occurrence and mobility evaluation of shale oil under reservoir conditions.

Summary: In this study, a near-infrared light-regulated PDT nanoplatform (TPP-UCNPs@MOF-Pt) was constructed to overcome the limitations of tumor hypoxia in photodynamic therapy. The nanoplatform effectively relieved tumor hypoxia by converting H2O2 to oxygen and enhanced PDT efficacy under NIR light irradiation. Additionally, the TPP-UCNPs@MOF-Pt targeted mitochondria, causing mitochondrial membrane depolarization and activation of the apoptotic pathway, further amplifying the therapeutic efficacy. In vitro and in vivo experiments demonstrated the significantly enhanced photodynamic therapeutic efficacy of TPP-UCNPs@MOF-Pt. This study provides a promising strategy for the construction of an MOF-based multifunctional nanoplatform to address the limitations of PDT treatment for hypoxic tumors.

It is shown that the relative positions of the photonic bandgap of the hydrogel and the absorption band of Ce6 can tune the generation efficiency of singlet oxygen. The slow photons at the blue edge of the photonic bandgap exhibit advantages in improving singlet oxygen generation compared to those at the red edge.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
