As an intermittent energy source, the efficient utilization of solar energy relies on stable and efficient energy conversion and storage technologies. Phase change materials (PCM) have become ideal candidate materials for solar thermal storage due to their high energy storage density and reversible cycling characteristics. However, traditional organic solid-liquid phase transition materials are prone to leakage during the phase transition process and have a relatively low photothermal conversion efficiency, which limits their practical application. To address the above issues, this study designed a novel composite phase change material (CPCM). By collaboratively loading nanomaterials of different dimensions, such as copper nanowires (CuNWs) and MXene, into a graphene porous framework and encapsulating paraffin (PW), the reduced graphene oxide (rGO)/ CuNWs/MXene/PW (rGCuMPW) composite material was successfully constructed. Among them, the high light absorption capacity of MXene, combined with the excellent thermal conductivity of CuNWs, significantly improved the photothermal conversion efficiency (92.11 %) and thermal energy storage density (ΔH = 165.77 J·g −1 ) of the material. In addition, this material still maintains a stable phase transition enthalpy value after 100 cycles, demonstrating excellent cycle stability and reusability. The CuNWs-MXene synergistic modification strategy proposed in this study not only effectively reduces the leakage rate of organic PCM, but also significantly improves the performance of photothermal conversion and thermal energy storage, providing a new type of high-performance CPCM for the efficient utilization of solar energy.

Critical-sized bone defects pose a significant clinical challenge, with inadequate blood supply being a major factor impairing bone healing. In the initial stage of bone healing, the blood clot acts as a “natural glue,” serving not only as a scaffold for stem cell growth but also providing a reservoir of cytokines and growth factors that regulate and reconstruct the osteogenic microenvironment. In this study, we hierarchically integrated platelet concentrates with distinct functions into an injectable thermosensitive hydrogel, constructing a “biomimetic blood clot” system. First, leukocyte-platelet-rich fibrin (L-PRF) lyophilized powder, which promotes the osteogenic differentiation of periosteum-derived mesenchymal stem cells (PMSCs), was incorporated into methacrylated gelatin hydrogel microspheres (GM) to form GM L-PRF . Subsequently, advanced platelet-rich fibrin (A-PRF) lyophilized powder, which enhances the angiogenic differentiation of lamina propria-derived mesenchymal stem cells (LMSCs), was blended into a hydrogel precursor composed of chitosan (CS), polygalacturonic acid (PgA), β-glycerophosphate (β-GP), and GM L-PRF . This yielded a thermosensitive hydrogel, designated CSPgA A-PRF GM L-PRF (CP A G L ), which exhibits favorable mechanical properties at 37 °C and enables the programmed release of growth factors from both A-PRF and L-PRF. The CP A G L hydrogel could induce the differential differentiation of distinct types of MSCs. It facilitates vascularized bone regeneration by activating the JAK2-STAT3/HIF-1α and the TGF-β/Wnt signaling pathway, thereby effectively initiating the coupled an gio -osteogenic process. In summary, the biomimetic blood clot system CSPgA A-PRF GM L-PRF represents a potential injectable biomaterial strategy for bone defect repair.

This work focuses on the development of a paraffin-based shape stabilization phase change composite containing chitosan@polypyrrole aerogel as a skeleton carrier for low temperature thermal energy storage and efficient photothermal conversion. Such a composite is fabricated by incorporating the three-dimensional network aerogel, that synthesized through the deposition of polypyrrole on the pores of chitosan using the in situ oxidation and polymerization processes. Characterization results indicate that polypyrrole and chitosan are bonded via hydrogen bridges, forming a rigid and open-celled network structure that is able to accommodate the liquid paraffin with a mass ratio as high as 93.25%. At such a composition, the composite achieves a melting temperature of 36.86 °C and a latent heat of 194.95 J/g. The doping of polypyrrole largely improves the composite thermal stability and thermal conductivity. In comparison with the pure paraffin, the thermal decomposition temperature and thermal conductivity of the composite containing 9.66 wt% chitosan@polypyrrole aerogel are respectively enhanced by 33.7% and 3.26 times. Splendid thermal cycling performance is also achieved in the composite. After 300 repeated heat-cold cycles, the paraffin concentration is only decreased by 4.35%, and no apparent leakage or deformation is observed in the composite. Photothermal conversion tests reveal that polypyrrole endows the composite with highly efficient broadband light absorption capabilities. Under simulated sunlight irradiation of 100 mW/cm 2 , the heating rate of the composite can reach 33.74 °C/h, and the photothermal conversion efficiency is up to 73.22%.

To develop energy-efficient building coatings with enhanced thermal energy storage performance, paraffin/sepiolite composite phase change coatings were prepared using ultrasonic-assisted acid-activated sepiolite as a supporting matrix. The effects of acid treatment duration on the structural properties of sepiolite and the performance of the resulting coatings were systematically investigated. The results showed that acid activation for 1 h produced the optimal pore structure, yielding a maximum internal specific surface area of 125.881 m2g−1. Longer treatment durations (>2 h) caused structural degradation and possible deterioration of pore structure. The paraffin/sepiolite composite phase change material prepared with JK-1 h exhibited a latent heat of 77.29 J g−1, outperforming that prepared with JK-2 h. Increasing the paraffin and CPCM contents enhanced the thermal storage capacity of the coatings; however, excessive CPCM loading deteriorated film integrity, resulting in cracking, reduced adhesion, and decreased hydrophobicity. Among all formulations, sample S3 demonstrated the best overall performance, with a latent heat of 33.51 J g−1, a pull-off strength of 5.9 MPa, and a water contact angle of 102.53°. Thermal cycling tests further confirmed its excellent thermal reliability and reusability. These findings indicate that paraffin/sepiolite composite phase change coatings have considerable potential for reducing building energy consumption and improving indoor thermal regulation.

A colchicine-loaded nanoemulgel (COL-nEMG) was developed for rapid and potent topical therapy of acute gouty arthritis (AGA). An O/W COL-loaded nanoemulsion (COL-nEMS, 14.20 ± 1.73 nm) was first prepared and optimized step by step, including excipient screening, pseudo-ternary phase diagram, in vitro transdermal delivery and D-optimal design. The optimized COL-nEMS containing 10% isosorbide dimethyl ether (DMI) was then dispersed into a gel matrix to produce the final COL-loaded nanoemulgel (COL-nEMG-DMI10). COL-nEMG-DMI10 exhibited a homogeneous appearance, favorable rheological properties, stable three-dimensional porous structure, and good storage stability with a steady-state transdermal flux of 54.6 ± 3.7 µg/cm²/h and 8 h cumulative permeation amount of 425.6 ± 28.3 µg/cm². In an AGA mouse model, COL-nEMG-DMI10 demonstrated rapid therapeutic effects with joint swelling inhibition rate (JSIR) of 37.0 ± 3.4% and maximum possible effect of 37.5 ± 5.3% at 1 h post-administration. In addition, COL-nEMG-DMI10 significantly suppressed the levels of local inflammatory cytokines, including TNF-α and IL-1β, in the ankle joints of AGA animals. This COL-nEMG-DMI10 topical formulation provides a promising treatment strategy for AGA with rapid and pronounced therapeutic efficacy.

Constructs a bilayer passive cooler integrating radiative and evaporative cooling. • Achieves high solar reflectance and strong mid-infrared emissivity. • Enables rapid moisture sorption and stable evaporative cooling. • Reduces building cooling energy consumption across diverse climate zones. The rapidly growing demand for space cooling, driven by urbanization and climate change, poses significant challenges to energy sustainability and carbon mitigation. Passive daytime radiative cooling offers a promising low-energy cooling strategy but is fundamentally constrained by climatic sensitivity and limited cooling power. Here, inspired by thermohygroregulation in desert mammals, we report a self-sustained coupled radiative-evaporative (CRE) cooling material that integrates radiative and evaporative cooling within a bilayer architecture. The CRE cooler comprises a porous polyethylene aerogel top layer with ultrahigh solar reflectance (∼98.0%) and high mid-infrared transparency, and a salt-based hygroscopic composite bottom layer encapsulated within a porous polytetrafluoroethylene membrane, enabling reversible moisture sorption and evaporation through a closed water cycle. Benefiting from hierarchical pore engineering, the CRE cooler exhibits high mid-infrared emissivity (∼0.92), low thermal conductivity (∼38 mW m −1 K −1 ), rapid moisture uptake (up to 1.72 g g −1 at 60% RH), and weakly humidity-dependent evaporation behavior. Outdoor experiments demonstrate robust daytime cooling of up to ∼5.1 °C relative to an uncovered control and ∼2.6–3.0 °C compared with a radiative-only cooler under both sunny and cloudy conditions. Building energy simulations across 18 global cities reveal annual cooling energy savings of 6.7%–21.2% and carbon emission reductions of 1.5–5.0 tCO 2 -eq. This work establishes a biomimetic and climate-resilient strategy for synergistic passive cooling with strong potential for low-carbon building thermal management.

The therapeutic efficacy of transarterial chemoembolization (TACE) is strongly limited by the hypoxic and immunosuppressive tumor microenvironment (TME). Herein, monodisperse perfluorooctyl bromide (PFOB)-loaded fucoidan/gelatin microspheres (P@FGMS) with excellent oxygen-carrying capability were prepared for enhanced TACE treatment of hepatocellular carcinoma (HCC). It was found that the introduction of fucoidan endowed P@FGMS with excellent electrostatic affinity for positively charged doxorubicin (DOX) and metformin (MET), enabling their efficient co-loading and sustained release. The resulting drug-loaded microspheres (DMP@FGMS) largely enhanced chemotherapy sensitivity through an in-outside hypoxia remodeling strategy: the supplement of exogenous O 2 via PFOB and inhibition of intracellular oxygen consumption by MET. Notably, DMP@FGMS could not only modulate hypoxic TME, but also generate intracellular ROS and disrupt the redox homeostasis, thereby triggering cancer ferroptosis. Moreover, DMP@FGMS effectively remodeled the immunosuppressive TME by alleviating tumor hypoxia and inducing immunogenic cell death (ICD), thereby enhancing CD8 + T cell infiltration while reducing immunosuppressive cell populations. Consequently, DMP@FGMS could effectively suppress tumor growth in an orthotopic HCC rat model, with this effect further potentiated by combination with immune checkpoint blockade therapy. Therefore, this study demonstrates that DMP@FGMS is a potent embolic agent capable of remodeling the hypoxic/immunosuppressive TME, representing a promising strategy for TACE treatment of HCC.

The development and functional utilization of light-colored lignin are largely hindered by uncontrolled condensation reactions during extraction, which reduces lignin reactivity and compromises its functional performance. Herein, a formic acid/L-Cysteine (FA/L-Cys) pretreatment system was developed to fractionate functional light-colored lignin from bamboo. Under mild conditions (100 ° C, 1 h), this system achieved 95.3% delignification and 71.3% lignin recovery, affording pale beige lignin with a lightness value of 80.9. 2D-HSQC NMR analysis revealed that L-Cys suppressed lignin condensation by nucleophilically trapping reactive intermediates. When incorporated into a sun protection factor (SPF) 15 sunscreen formulation at 5 wt %, the optimized lignin (L-Cys-0.3) increased the SPF to 71.7. Moreover, L-Cys-0.3-derived lignin nanoparticles efficiently stabilized Pickering emulsions and exhibited a 12-fold enhancement in UV absorption capacity compared with their LNPs aqueous dispersion counterparts. This work highlights condensation-controlled fractionation as an effective strategy for producing light-colored lignin with potential applications in sustainable sunscreens and functional Pickering emulsion systems.

The spatial distribution of magnetic nanofillers within fibrous carbon scaffolds determines both impedance matching and broadband attenuation, yet the aerodynamic forces governing filler rearrangement during spinning remain unexploited as a design variable. We demonstrate that an L-shaped precursor needle within a solution blow spinning nozzle generates asymmetric aerodynamic shear. This shear converts the near-nozzle gas flow from a symmetric annular jet into a localized asymmetric forcing field. Large-eddy simulations reveal gas-phase shear rates above 3.0 × 10 5 s − 1 and coherent vortical structures absent in conventional nozzles. The near-nozzle extensional stress exceeds the van der Waals cohesion of Co@BCN bundles, consistent with the disaggregated cobalt domains observed after carbonization. Post-carbonization electron microscopy and elemental mapping reveal discrete cobalt domains within the carbon nanofiber matrix, a configuration that enhances interfacial polarization while suppressing percolative conductivity. At 10 wt.% filler loading in the paraffin matrix, the optimized Co@BCN-CF-2 achieves a minimum reflection loss of −69.4 dB at 8.08 GHz (3.4 mm). The effective absorption bandwidth reaches 5.2 GHz (2.2 mm), and the simulated radar cross-section reduction attains 20.98 dB. These findings establish near-nozzle aerodynamic forcing as a demonstrated, tunable processing variable for filler-domain assembly in the present Co@BCN/PAN SBS nanofiber system.

Diabetic patients frequently experience impaired healing of tooth extraction wounds, likely due to excessive reactive oxygen species (ROS) in the diabetic bone microenvironment, which compromises bone marrow mesenchymal stem cells (BMSCs). While Prussian blue nanoparticles (PBNPs) show promise as ROS scavengers, their clinical application remains limited due to the lack of stable, targeted and minimally invasive delivery systems. To address this, we developed an injectable microsphere system encapsulating PBNPs through microfluidic technology (GelMA/PEGDA/PBNPs). These microspheres exhibited excellent mechanical properties, controlled biodegradability, a pro-proliferative microenvironment, and photoacoustic imaging (PAI) tracking capabilities. In vitro, they significantly enhanced stem cell expansion, reversed oxidative stress in BMSCs, and enhanced osteogenesis. In vivo, these microspheres, through surface-loaded stem cell delivery, accelerated regeneration of irregular bone defects in tooth extraction sockets in diabetic rat. Transcriptomic sequencing analysis indicated that the antioxidant effects of the microspheres were closely associated with activation of the PI3K/AKT/mTOR signaling pathway. The optimized system enhanced local retention, achieved sustained and stable release of PBNPs, improved bioavailability of PBNPs, and enabled real-time tracking of the implants. This nano-hybrid microsphere system provides a novel minimally invasive therapeutic strategy for bone tissue defects in diabetic patients, demonstrating significant potential for clinical translation.

Electromagnetic pollution constitutes an emerging environmental and health threat, and the escalation is driving the search for sustainable and efficient mitigation technologies. This study presents an environmentally friendly and scalable solution through the design of composite nanofibers for effective electromagnetic pollution control. Utilizing the energy-efficient and industrially compatible solution blow spinning (SBS) technique, we successfully constructed a three-dimensional porous network within carbon fibers by integrating SiO 2 nanoparticles and in-situ pyrolyzed Co@BCN nanotubes. The design not only features SiO 2 as a dielectric modulator that optimizes impedance matching, but also induces abundant heterointerfaces with the carbon matrix and Co@BCN nanotubes, significantly enhancing interfacial polarization loss. The optimal material achieves a minimum reflection loss (RL min ) of −70.3 dB at a thickness of 1.8 mm and an effective absorption bandwidth (EAB) of 5.2 GHz at a thickness of 2.3 mm, significantly reducing material usage and promoting lightweight design. The study demonstrates that high performance and environmental sustainability can be synergized, providing a new pathway for developing next-generation green electromagnetic protection materials that align with the goals of sustainable industrial development.

Phase-change materials (PCMs) possess great potential for latent heat storage and thermal regulation, yet their practical application is often hindered by leakage during phase transitions. Here, we report an efficient strategy for PCM encapsulation based on the co-assembly of cellulose nanocrystals and oil-soluble dimethyl distearylammonium chloride, which stabilizes the water-paraffin wax (PW) interface. Cellulose nanocrystal surfactants (CNCSs) are formed in situ at the interface, where their high interfacial activity and jammed multilayer structure enable the preparation of stable PW-in-water emulsions. Freeze-drying of these emulsions yield PCM microcapsules with robust CNCS shells that can effectively prevent leakage during heating. Polymerization of the emulsion continuous phase produces phase change hydrogels with uniformly distributed PCM microcapsules, exhibiting excellent thermal insulation, heat-regulation, and thermal-protective properties.
