In recent years, with the development of electric vehicles and electric vessels, the issues of battery thermal safety have garnered significant attention. Composite phase-change materials (CPCMs) hold great potential as passive cooling systems in battery thermal management systems (BTMS), but their high flammability remains an unresolved challenge. This study successfully developed a flexible composite phase-change material, CPCM/P-CSF@rGO, by encapsulating a eutectic phase-change material composed of mannitol and galactitol in a three-dimensional hydrogen-bonded network, self-polymerised by phosphated corn straw cellulose (P-CSF) and reduced graphene oxide (rGO). The study demonstrates that the strong hydrogen bonding network formed between the phosphate groups introduced by phosphoric acid modification and rGO constructs highly efficient thermal conduction pathways, achieving a thermal conductivity of 1.039 W/(m•K) and significantly accelerating thermal response rates. Simultaneously, the incorporation of the P-CSF@rGO framework endows the material with excellent flexibility and shape stability. Due to the in-situ flame-retardant modification of the framework, the phase-change material maintains a high latent heat of phase-change (194.7 J/g) and achieves superior flame retardancy through gas-phase and condensation-phase mechanisms. It exhibits a limiting oxygen index of up to 30.64% and rapidly extinguishes itself when exposed to open flame in atmospheric conditions. Thus, the flexible composite phase-change material (CPCM/P-CSF@rGO) supported by a phosphorylated cellulose framework emerges as a promising candidate for ensuring safety and high performance in thermal management applications.

With increasing environmental awareness, developing renewable and biodegradable bio-based greases is a research priority. Herein, phosphorylated cellulose nanofibrils (PCNF) were selected as a bio-based thickener due to their renewability, excellent network-forming ability, and improved interfacial properties. However, the inherent hydrophilicity of PCNF limits its compatibility with non-polar vegetable oils. To overcome this, methyltrimethoxysilane (MTMS) was used for hydrophobic modification of PCNF, and fully bio-based greases were fabricated by combining modified PCNF (M-PCNF) with castor oil. The effects of MTMS silanization degree and M-PCNF content on the microstructure, physicochemical properties, rheology, and tribology of the greases were systematically investigated. Results show that increasing silanization degree enhances penetration, oil separation, and mechanical stability but reduces viscosity and structural strength. Increasing M-PCNF content improves thickening capacity, viscosity, structural strength, and rebuild rate. Notably, the friction coefficient of M-PCNF-based greases stabilizes at 0.04–0.06, lower than that of commercial lithium grease, demonstrating excellent friction-reducing stability. This work provides a feasible strategy for high-performance bio-based greases and offers insights into structure–property relationships relevant to cellulose-based thickener design for green lubrication.

Multidrug resistance (MDR) remains a central obstacle in cancer therapy, accounting for over 90% of cancer-related mortality. Although calcium overload has emerged as a promising anticancer strategy, its clinical translation is largely limited by insufficient tumor selectivity. Hydroxyapatite nanoparticles (HAPNs) possess intrinsic biocompatibility and the ability to induce tumor-specific Ca 2+ overload; however, conventional synthesis methods often yield polydisperse and aggregation-prone particles, resulting in high dosage requirements and inconsistent antitumor efficacy. Herein, we reported a tumor-targeting monodisperse hydroxyapatite core–shell nanospheres (TMHCNs) fabricated via microfluidic coaxial chips (MCC)-assisted soft-templating strategy to achieve precise physicochemical control for tumor-specific synergistic Ca 2+ overload therapy. FDA-approved components, sebacic acid, glycerol, and polyethylene glycol, were used to compose uniform nanomicelles as soft templates for homogeneous mineralization, enabling reproducible generation of uniform core–shell nanospheres. Subsequent surface functionalization with hyaluronic acid (HA) yielded monodisperse tumor-targeting nanospheres, TMHCNs (47.0 ± 5.0 nm) with enhanced CD44-mediated cellular uptake. The antimalarial drug and sarcoplasmic/endoplasmic reticulum Ca 2+ -ATPase (SERCA) inhibitor, artemisinin (Art), was then selected and encapsulated into TMHCNs to construct the synergistic Ca 2+ overload nanosystem Art@TMHCNs. TMHCNs alone induced sustained and tumor-selective intracellular Ca 2+ overload. Loading the SERCA inhibitor Art further amplified tumor-specific Ca 2+ overload, triggered mitochondrial dysfunction, depleted ATP, and activated both intrinsic and extrinsic apoptotic pathways, thereby effectively reversing MDR. In an A549/PTX xenograft model, Art@TMHCNs achieved complete tumor growth suppression and pronounced tumor-specific calcification with minimal off-target toxicity. This work establishes a precisely engineered, monodisperse hydroxyapatite core–shell platform that amplifies tumor-specific calcium dysregulation and provides a clinically translatable strategy for safe and effective MDR reversal in cancer therapy.

High-intensity focused ultrasound (HIFU) has emerged as a game-changing breast-conserving therapeutic modality owing to its dual functions of non-invasive tumor ablation and immunity activation. However, its low focal gain in the target region results in residual tumor tissue after ablation. Inspired by the exceptional acoustic response of bone tumor to HIFU, we developed bone-derived hydroxyapatite (HA)-mineralized metal-organic frameworks (designated as AZSH MOFs) as sonosensitizer that co-encapsulated Zn 2+ , hypoxic-activated prodrug AQ4N, and STING agonist SR-717 for acoustic-immunological synergistic therapy. AZSH MOFs enabled targeted delivery of HA to mimic bone tumor-like acoustic environment, markedly amplified HIFU energy deposition in the breast tumor tissue, and thus achieved more thorough ablation and local hypoxic. The exacerbated hypoxic selectively activated AQ4N to trigger immunogenic cell death. Meanwhile, Zn 2+ with SR-717 upregulated stimulator of interferon genes (STING) pathway to promote intratumoral infiltration of immune cells, and ultimately relieved the immunosuppressive tumor microenvironment. Thus, AZSH MOFs not only improve ablation efficiency of HIFU but also treat residual tumor via enhanced multilevel immune activation, offering valuable insights to facilitate the extensive clinical application of HIFU technology.

Natural biomaterial-derived membranes show great potential for guided bone regeneration (GBR) and bone tissue engineering due to excellent biocompatibility and degradability. While incorporating inorganic nanoparticles like hydroxyapatite (HA) is a common strengthening strategy, the systematic impact of nanoparticle morphology on the integrated performance of composite membranes remains a critical, yet underexplored, knowledge gap. Here, we developed chitosan (CS)-based composite membranes incorporating hydroxyapatite (HA) nanoparticles of four morphologies: large lamellar (LHA), small lamellar (SHA), wire-like (WHA), and rod-like (RHA). Additionally, HA’s capacity as an ion carrier enabled the loading of silver (Ag) to impart antibacterial properties. High-aspect-ratio fillers (LHA, WHA) promoted crack deflection and energy dissipation, achieving tensile strengths up to 82.47 ± 4.10 MPa and toughness up to 28.61 ± 5.02 MJ·m −3 —significantly outperforming pure CS membranes. This reinforcement mechanism extended to other matrices, such as sodium alginate. Simultaneously, the Ag-loaded HA (Ag-HA) composite membranes synergistically enhanced osteogenic activity (alkaline phosphatase) and exhibited strong antibacterial efficacy. These findings elucidate morphology–size–performance correlations, providing a framework for designing multifunctional GBR biomaterials with enhanced mechanical properties, osteogenesis, and antimicrobial capabilities.

In-situ preparing robust CoFe 2 O 4 /PCN PMS activator for multi-pollutant degradation. • Complete degradation TC within 3 min with the rate constant 24-fold higher than CN • Degradation intermediates, routes and toxicity were explored • Wide light absorption, exposed active sites, and charge behavior boost photocatalysis Facing the urgent environmental crisis, it is imperative to create an efficient and robust technology for treating diverse pollutants in aquatic environments. Herein, a CoFe 2 O 4 /PCN composite was designed via a facile in-situ growth method, in which CoFe 2 O 4 uniformly grows on carbon nitride. This architecture not only forms a close interface that facilitates efficient charge separation and migration, but also introduces abundant mixed-valence metal sites, that serve as superior active centers for peroxymonosulfate (PMS) activation and subsequent organic pollutant removal. Specifically, under visible light, the optimized catalyst can 100% degrade TC within 3 min (complete degrade rhodamine B within 20 s, methyl orange within 40 s, and methylene blue within 3 min), and the rate constant was 24-fold higher than pristine CN, surpassing most reported catalysts. The catalyst also demonstrates excellent recyclability and broad pH adaptability. The mechanism behind the performance enhancement stems from the significantly broadened light absorption (supported by UV–vis DRS), fully exposed active sites (evidenced by SEM/TEM/AFM and N₂ adsorption), and enhanced charge behaviors (supported by PCR, EIS, PL/TRPL and KPFM), especially caused by strong internal electric field. At last, the active species, degradation intermediates and their toxicity were investigated using TC degradation as a model, coupled with DFT theoretical calculations. This work proposes a rational design strategy toward constructing efficient and robust photocatalysts, revealing significant promise for water remediation.

Octacalcium phosphate (OCP) is a biodegradable material with excellent biocompatibility and osteoinductive activity, showing great promise in bone repair applications. Although silk fibroin (SF) demonstrates osteogenic potential and SF-modified OCP has shown enhanced mineralization and osteogenesis in vitro, the underlying regulatory mechanism remains unclear. In this study, by combining cryo-transmission electron microscopy analysis and density functional theory (DFT) calculations, the SF-modified OCP is revealed that possesses a higher density of dislocations. The hydrophobic amino acid sequence of SF induced the formation of edge dislocations via an “adsorption-epitaxy-extrusion” mechanism, accompanied by changes in adsorption energy, which facilitated the transformation of OCP into hydroxyapatite (HAp) and enhanced osteoinduction. In vitro experiments further confirmed that SF-modified OCP enhanced cytocompatibility, promoted ALP and ARS activity, upregulated osteogenic gene expression, and strengthened osteogenic protein expression. This work proposed a novel strategy for modulating defect structures in bioceramics through organic molecules and demonstrated the potential of dislocation-engineered SF-OCP for bone defect repair.

Wood surface superhydrophobic modification effectively mitigates liquid–water–induced shrinkage/swelling, enhancing dimensional stability. However, most researches focus on wood transverse sections due to inherent roughness, whereas few have achieved superhydrophobicity on environmentally exposed tangential surfaces. Furthermore, practical application of superhydrophobic wood remains challenging due to its poor interfacial stability. Herein, a scalable alkali etching strategy that partially removes hemicellulose/lignin to enhance roughness and active sites on wood tangential surfaces is proposed. Subsequent spraying of hydroxyapatite-polydimethylsiloxane (HAP-PDMS) composite solution forms a robust superhydrophobic coating. Etching-induced microcracks and voids facilitate nanoparticle anchoring, synergistically functioning with the cellular framework as a protective barrier to ensure exceptional durability. The modified surface can withstand mechanical abrasion, chemical corrosion, and UV exposure, retaining superhydrophobicity after 60-day outdoor aging. Notably, it exhibits autonomous self-healing: post seven abrasion-repair cycles, the water contact angle recovers to 142° (92.4% restoration efficiency). This work provides an economical route to engineer stable superhydrophobic tangential wood surfaces, extending product service life. Graphical abstract

Transition metal (TM) doped transition metal oxides (TMOs) have emerged as promising materials for supercapacitor application due to their redox activity, large surface area, and high specific capacitance. However, optimizing their electrochemical properties remains challenging. In this work, we have synthesized Ni- and Co-doped CuO nanocomposites via a straightforward hydrothermal approach to examine the effects of doping on their nanostructure, crystallinity, and redox properties. Additionally, machine learning (ML) was employed to optimize fabricated material composition to enhance the electrochemical efficacy of the designed materials. Results demonstrate that ML-optimized Ni-doped CuO has shown a high specific capacitance of 496 Fg −1 at a current density of 1.5 Ag −1 as compared to Co-doped CuO (245 Fg −1 ). Ni-doped CuO achieved a high-power density of 12,469 Wkg −1 and energy density of 111 Whkg −1 , demonstrating enhanced electrochemical performance. The improved properties of Ni-doped CuO are attributed to enhance synergistic effect between Ni-doped CuO, which facilitates faster electron transfer and enhances the material's stability and achieved capacitance retention of 95.1 %. This study presents an economical and effective method for optimizing TM-doped CuO nanocomposites. Ni-doping exhibits excellent performance, which offers significant potential for next-generation energy storage devices.

A microscale zero-valent iron (mZVI) composite integrating surface phosphate (P) modification and lattice nitrogen (N) doping (NP-mZVI) was successfully fabricated by one-step mechanochemical method in aim to establish synergistic adsorption-reduction pathways for enhanced Cr(VI) removal. NP-mZVI demonstrated superior reactivity for Cr(VI) removal with 100% of both removal efficiency and conversion rate, which significantly outperform the pristine ball-milled mZVI bm and P-modified mZVI bm . Furthermore, NP-mZVI also exhibited excellent removal performance for a range of heavy metals (e.g., Ni(II), Pb(II), Cu(II), and Cd(II)), and was also demonstrated to be pH-universal, long-term stability, and environmental applicability. The strategic integration of lattice N doping and surface P coordination in NP-mZVI establishes a dual-path optimization mechanism for enhanced Cr(VI) removal. Surface P groups enable bidentate Cr(VI) complexation through ligand-specific recognition, reducing adsorption energy barriers while creating Fe-O-P mediate directional charge transfer. Concurrently, interstitial N doping induces lattice tensile strain via Fe Fe bond elongation, weakening metallic bonding networks to amplify electron liberation from the Fe 0 core. N facilitates electron release through strain engineering while P directs interfacial electron utilization. This synergistic coupling of core activation and surface mediation resolves the kinetic mismatch between electron supply and interfacial demand, achieving superior Cr(VI) removal efficiency through adsorption-reduction pathway integration. This study highlighting the synergistic effects of surface P modification and lattice N doping for mZVI in enhancing the reduction and removal of Cr(VI), and provides a new insight into rational design of modified mZVI with high reactivity.

As a renewable building material, wooden material is susceptible to frost and icing when exposed to harsh outdoor conditions, which not only severely affects the service life of wood but also cause significant safety hazards. Constructing superhydrophobic wooden surfaces with photothermal functions is an effective way to delay droplet freezing and ice accumulation. However, this modification strategy always involves complex preparation processes, and the durability of these superhydrophobic wooden surfaces is unsatisfactory. In this work, a one-stone-two-birds tactic to construct durable superhydrophobic wood/bamboo surface with photothermal effect was proposed. By thermally decomposing wood pre-coated with a polydimethylsiloxane/hydroxyapatite nanospheres (PDMS/HAP) layer, PDMS was converted into silica nanoparticles with silane on the surface, and a carbon layer with photothermal conversion properties was formed on the wooden surface. The simultaneous generation of hydrophobic silica nanoparticles and a carbon layer endowed the wood/bamboo surface with durable superhydrophobic properties and photothermal conversion capabilities. This method can be applied to various wood species and bamboo. The obtained wooden superhydrophobic surface exhibited a water contact angel of 160.5°, and has excellent durability. This superhydrophobic surface could not only withstand physical abrasion such as sandpaper abrasion and water impact, but also maintain its superhydrophobicity after exposure to chemical corrosion and UV irradiation. This superhydrophobic layer also provided the wooden materials with good dimensional stability and moisture resistance. In addition, the photothermal conversion effect enabled the wood surface to rapidly rise to 55.3 °C under one sun illumination, and ice crystals slid off its surface within 8 s. This work presents a simple and promising strategy for constructing photothermal and superhydrophobic layer on wood/bamboo surface, and is expected to mitigate the frosting and icing problems of wooden building materials in cold conditions and extend their service life.

Stabilizing metastable active centers under harsh reaction conditions represents a significant challenge in heterogeneous catalysis. The F-Al-O species exhibits excellent catalytic activity for the gas-phase dehydrofluorination of potent greenhouse gas hydrofluorocarbons (HFCs) to produce hydrofluoroolefins (HFOs). However, this species is prone to transform into the F-Al-F configuration via excessive fluorination, subsequently leading to catalyst deactivation because of coke deposition. To address this issue, we present a viable strategy for stabilizing the metastable active centers. Al 2 O 3 doped with boron (B), phosphorus (P), and sulfur (S) was synthesized via the sol-gel method. Results demonstrate that in the dehydrofluorination of HFC-245fa, the phosphorus-doped Al 2 O 3 catalyst (P-Al 2 O 3 ) outperforms its boron- and sulfur-doped counterparts, achieving a conversion of 87% compared to 68% and 49%, respectively. The incorporation of P significantly alters the coordination environment of Al 3 + within the Al 2 O 3 lattice, forming O-Al-O-P bonding configurations. During the subsequent dehydrofluorination reaction, these structures undergo fluorination to yield HF-resistant F-Al-O-P species. This process effectively impedes the deep fluorination of Al 2 O 3 into AlF 3 , thereby stabilizing the metastable F-Al-O active centers. Furthermore, this anti-fluorination mechanism significantly suppresses catalyst coking and prevents pore structure collapse. In the dehydrofluorination of HFC-245fa to HFO-1234ze, the P-Al 2 O 3 catalyst achieved a high conversion of 87%, representing an approximately threefold enhancement over conventional Al 2 O 3 , and no significant deactivation trend was observed after 500 h of reaction. This work provides a fundamental understanding of stabilizing metastable active centers and paves a practical pathway for designing robust catalysts for reactions under corrosive atmospheres.
