This review systematically examines the synthesis-structure-property relationships of hybrid graphene and carbon fiber reinforced composites, encompassing polymer, metal, and ceramic matrix systems. The hybridization of graphene with carbon fibers addresses the intrinsic limitations of conventional composites, such as weak interfacial bonding and insufficient multifunctionality. The review consolidates recent advances in fabrication strategies, including electrophoretic deposition, layer-by-layer assembly, and precursor impregnation, which enable controlled graphene distribution and orientation. Critical analyses of mechanical, tribological, electrochemical, and anti-ablation properties reveal that graphene addition significantly enhances interfacial shear strength, thermal stability, and electrical conductivity. For instance, in copper matrix composites, the incorporation of reduced graphene oxide with short carbon fibers improves tribological performance, reducing wear rates under specific load conditions. In ceramic matrix composites, graphene-modified C/C-SiC composites exhibit superior anti-ablation resistance, with mass loss rates reduced by up to 30% at elevated temperatures. Furthermore, graphene-coated carbon fiber electrodes demonstrate high specific capacitance and cycling stability in energy storage applications. The review also addresses challenges such as dispersion uniformity, scalability, and cost-effectiveness, proposing future directions for industrial adoption. By providing a comprehensive framework, this work guides the design of next-generation hybrid composites tailored for aerospace, automotive, and energy storage sectors.

Continuous monitoring of 114 volatile organic compounds (VOCs) was conducted in the urban atmosphere of Haigang District, Qinhuangdao City, from September 2022 to February 2023. The volume concentrations of total VOCs were 42.72×10⁻⁹ in autumn and 25.15×10⁻⁹ in winter. The predominant species were isopentane, ethane, and ethylene. Ozone formation potential (OFP) analysis indicated that alkanes and alkenes dominated the atmospheric pollution during autumn and winter, with isopentane and ethylene being the largest contributors. Aromatic hydrocarbons contributed up to 85.00% of the secondary organic aerosol formation potential (SOAFP), with benzene as the primary species. Positive matrix factorization (PMF) identified four major sources: technological processes and oil/gas volatilization (35.57%), combustion and petrochemical emissions, motor vehicle emissions, and regional background sources. The results underscore the need for targeted control of VOCs from industrial and vehicular sources to mitigate secondary pollution in coastal cities.

Halide perovskite nanocrystals (PNCs) exhibit high photoluminescence quantum yield (PLQY), narrow full width at half maximum (FWHM), and high color purity, yet their intrinsic instability under ambient, thermal, and photonic stress restricts deployment in optoelectronic devices. Embedding CsPbX3 (X = Br, I) PNCs within inorganic glass matrices mitigates degradation, but dense glass networks impede nucleation and growth. This work adjusts the GeO2-SiO2-B2O3 glass network via B2O3 addition to create loose, compact structures that facilitate PNC precipitation. Optimized CsPbBr3@Glass achieves a PLQY of 85%. Glass powders with varying particle sizes are screened for stability, identifying an optimal size range. Composite films of CsPbX3@Glass@PS (X = Br, I) with polymer materials yield light conversion films. Under 120 h blue light irradiation, green-light samples outperform red-light samples in stability. In situ heating-cooling cycles show thermal recovery exceeding 90% for green and 86% for red samples. A white light-emitting diode (WLED) constructed with CsPbBr3@Glass, CsPbBrI2@Glass, and a 460 nm InGaN chip achieves a color gamut covering 123% of NTSC 1953 and 91.8% of Rec 2020. An LCD incorporating green CsPbBr3@Glass@PS and red CsPbBrI2@Glass@PS films with a 450 nm mini-blue chip retains >90% of initial PL intensity after 15 days in 95% ethanol, demonstrating dual protection from glass and polymer. These results establish a pathway for stable, wide-gamut display backlights.

This study addresses the intermittent nature of solar energy by developing a dual-mode energy storage material. A bulky azobenzene derivative, 4’-aminoazobenzene-4-sulfonic acid (AABS), was grafted onto the surface of ZIF-90, yielding ZIF-90-AABS (ZIF-AABS). The surface template effect enables reversible cis-trans isomerization of AABS, achieving photochemical energy storage of 5.1 J g−1. Because AABS is confined to the surface, ZIF-AABS retains the crystalline porous structure of ZIF-90, allowing encapsulation of octadecyl alcohol (OD) as a phase change material (PCM). The resulting composite, OD/ZIF-AABS, exhibits a latent heat storage capacity of 121.3 J g−1 at maximum OD loading, with no significant degradation after 50 melting/solidifying cycles. This work demonstrates a synergistic approach that combines photochemical and phase-change energy storage within a single MOF-based platform, expanding the application scope of azobenzene and MOF composites for solar energy storage.

Bacterial infection disrupts wound repair through sustained inflammatory responses and impaired angiogenesis, while antibiotic resistance severely limits conventional therapies. This study reports a dissolving microneedle (MN) system for transdermal delivery of ε-poly-L-lysine (EPL)/hyaluronic acid (HA) nanoparticles (EH NPs) to eliminate methicillin-resistant Staphylococcus aureus (MRSA) and accelerate wound healing. Electrostatic co-assembly of EPL and HA yields nanoparticles with enhanced cellular phagocytosis, enabling combined antimicrobial, angiogenic, and anti-inflammatory activities. In vitro, the MN system eradicates >99.9% of MRSA, upregulates endogenous nitric oxide release and CD31 expression in human vascular endothelial cells, and promotes macrophage polarization from M1 to M2 phenotype. In a drug-resistant bacteria-infected skin wound mouse model, the MN system significantly enhances granulation tissue formation and collagen deposition by promoting angiogenesis and reducing inflammation, thereby accelerating wound closure. This multifunctional microneedle platform addresses the limitations of conventional dressings by overcoming the skin barrier for efficient transdermal delivery of synergistic bioactive nanoparticles, offering a promising clinical strategy for infected wound management.
