The rapid escalation of power density in modern electronic devices has heightened the demand for efficient thermal interface materials (TIMs) to ensure system reliability and stability. Silicone composites incorporating hexagonal boron nitride ( h -BN) fillers are widely used. However, their performance is hampered by weak interfacial interactions between BN and the polydimethylsiloxane (PDMS) matrix, which induce structural defects, intensify phonon scattering, and compromise mechanical flexibility and environmental adaptability. Here, we report a facile and scalable synthesis of a dual dynamic crosslinked polyborosiloxane (DN-PBS) elastomer. With its intrinsic self-healing capability, DN-PBS was employed as the thermal interface material matrix, within which a three-dimensional hydroxylated h -BN (BNOH) thermally conductive network was assembled using a novel blade-coating/lamination/hot-pressing strategy. The resulting DNPBS/BNOH composites exhibited room-temperature self-healing and high thermal conductivity, thus addressing the challenge of ordered h -BN assembly. Moreover, the synergistic interactions between coordination and hydrogen bonds endowed the material with autonomous healing at room temperature and markedly suppressed interfacial phonon scattering. At a BNOH loading of 40 wt%, the composite exhibits a superior thermal conductivity of 8.9 W m −1 K −1 (representing a 39-fold enhancement) and an ultralow thermal resistance of 1.19K cm 2 W −1 . Simultaneously, it demonstrates exceptional mechanical compliance, characterized by a low Young’s modulus of 0.88 MPa and a high elongation at break of 433.8%, alongside intrinsic room-temperature self-healability. Moreover, the low dielectric constant and dielectric loss ensured minimal signal attenuation and energy dissipation, rendering the material highly suitable for thermal management in advanced electronic devices under complex service environments. This work provides a promising platform for next-generation high-performance TIMs in emerging electronics.

Determining rare earth elements (REEs) and Sr-Nd isotope ratios at low abundance levels in ultramafic rocks remains a significant challenge. This study presents a simplified method for the separation of trace multi-elements using a tandem column of SR-TODGA resin combination, and thereby the elements at very low levels, and 87Sr/86Sr and 143Nd/144Nd ratios in ultramafic rocks were determined by inductively coupled plasma-mass spectrometry (ICP-MS) and thermal ionization mass spectrometry (TIMS). The samples were digested using HF-HNO3, and prepared to HNO3-H3BO3 solutions. After loading the sample solutions onto the tandem column, Sr was eluted from the SR resin column using 10 mL of 0.045 M HNO3. The TODGA column was eluted sequentially with 10 mL of 0.45 M HNO3 and 1.4 M HF for Zr, Hf, Th and U, 7 mL of 2.1 M HCl for La, Ce and Pr, 5 mL of 1.5 M HCl for Nd, and 10 mL of 0.06 M H2SO4 for other REEs (Sm-Lu and Y). The procedural recovery yields were evaluated by adding standards, and they ranged from 97.3% for La to 103.9% for Th. The blank ranges from 0.01 ng (Ho, Tm and Lu) to 24.4 ng (Sr). Eight ultramafic reference materials, JP-1, DTS-2b, UB-N, MUH-1, SARM-6, Harz01, DZΣ-1 and DZΣ-2, were analyzed, and the analytical results exhibit good agreement with certified and literature values. Therefore, the proposed method can be applied to accurately analyze both the contents of multi-elements at very low levels and Sr-Nd isotopic ratios in ultramafic rocks.

Polarization multiplexing has garnered increasing attention due to its superior performance in sensing, communication and imaging. Extensive studies in this field are mainly focused on metasurfaces, however, some drawbacks including high costs, complicated fabrication processes and the limited information capacity imped their practical applications. Herein, this study proposes a machine learning strategy to fabricate twisted-stacking functional films with user-specified polarization-responsive performances, achieving a robust mapping relationship among structural parameters, polarization states, and transmission characteristics. This work demonstrates a continuous manipulation of the spectra and the output color display by the arbitrary combinations of the input polarization channels and structure/process parameters, enabling accurate forward prediction of output displays and, consequently, allowing for the inverse design with a high information capacity (10 6 ) and information encryption. Moreover, by utilizing a reverse fully connected neural network for comparison and multi-region joint determination, this work proposes a novel fully polarization detection platform, favoring the identification of arbitrary unknown incident light.

Fermented fish products are gaining popularity in Chinese cuisine, with Chouguiyu emerging as a prominent example due to its distinctive flavor and economic value. Despite its growing appeal, the species-level microbial contributions to its quality and flavor remain underexplored. This study analyzed three different brands of Chouguiyu samples (S1, S2, S3), employing species-level microbial profiling to investigate their relationship with volatile organic compounds (VOCs), free amino acids, and other quality indicators. Key findings identified Leuconostoc citreum (S1), Lactiplantibacillus plantarum and Levilactobacillus brevis (S2), and Hafnia alvei (S3) as dominant strains, each correlating significantly with 17 major flavor compounds, 8 core free amino acids, and differential lipids. Notably, Leuconostoc citreum was associated with the production of Glutamic acid, Alanine, and various alcohols and aldehydes, enhancing product quality. Concurrently, it was observed that excessive fermentation reduced the flavor and quality of the product. These findings offer valuable insights into optimizing fermentation processes to improve the quality of Chouguiyu .

Developing efficient and stable electrocatalysts for the oxygen evolution reaction (OER) is essential for alkaline water electrolysis. Herein, ruthenium-doped cobalt phosphide encapsulated in open hollow nanoboxes of boron-nitrogen-codoped carbon (Ru-CoP/BNC-1) was successfully synthesized via a three-step strategy. Structural characterization revealed that the synergistic effect between Ru and boron- nitrogen-codoped carbon quantum dots (BCQDs) facilitated the selective etching of the ZIF-67 precursor, leading to a unique nanostructure with abundant lattice distortions and a high specific surface area after phosphidation. X-ray photoelectron spectroscopy (XPS) and in situ Raman spectroscopy confirmed that Ru doping effectively modulates the electronic structure of Co, promoting the formation of high-valent cobalt species, while B doping facilitates surface reconstruction via interfacial effects and leaching during OER, thereby optimizing the reaction pathway. Electrochemical measurements demonstrated that the catalyst delivers outstanding OER performance under alkaline conditions, requiring an overpotential of only 227 mV at 10 mA cm-2 and a Tafel slope of 80.01 mV dec-1, outperforming most reported cobalt-based catalysts and even commercial RuO2. Moreover, the catalyst exhibited excellent stability, showing negligible decay after 117 h of continuous operation at 50 mA cm-2. Density functional theory (DFT) calculations further revealed that the co-doping of Ru and B synergistically reduces the free-energy barrier for the *O-to-*OOH step, improving the reaction kinetics. This work provides a novel strategy for designing high-performance cobalt-based electrocatalysts through multi-element synergy.

Advanced thermal protection systems require ultralight, robust, thermally insulating, and ablation‑resistant composites. While promising, the three-dimensional (3D) skeleton/matrix design is challenged by fabricating an ideal skeleton with structural continuity, high‑temperature stability, interfacial compatibility, and scalability. Herein, we fabricate composite aerogels using an internally porous boron nitride (BN) fiber‑based 3D aerogel as the reinforcing skeleton and a phenolic (PF) aerogel as the matrix. The resulting PF/BN composite aerogels exhibit ultralow densities of 0.141–0.167 g/cm 3 . Excellent interfacial compatibility via π‑π interactions and hydrogen bonding ensures efficient stress transfer to the robust BN skeleton, preventing structural collapse during ambient pressure drying (APD) and endowing enhanced mechanical properties: up to 70% compressive strain and compressive strengths of 3.4–7.8 MPa. The aerogels also show outstanding thermal insulation, with the PF/BN2.0 sample exhibiting a low thermal conductivity of 45.3 mW·m −1 ·K −1 . Furthermore, under butane flame ablation (∼1300°C), a 20 mm‑thick PF/BN2.0 maintains a backside temperature of only 370°C after 15 min, and simply attaching it to an aluminum plate enables effective high‑temperature infrared stealth. This performance is attributed to a hierarchical structure formed in situ during ablation, consisting of a dense outer layer and a porous inner layer. This work not only demonstrates the effectiveness of the 3D BN fiber‑based skeleton as a high‑performance reinforcement, but also provides a new strategy for developing lightweight, multifunctional composites for extreme‑environment applications.

Mesophase pitch-based carbon fibers (CFs) with ultrahigh axial thermal conductivity can significantly enhance through-plane heat transfer in thermal interface materials by vertical alignment, yet raise short-circuiting and electromagnetic interference (EMI) risks. Although incorporating insulating fillers or coating CFs can suppress electron migration, it often compromises thermal performance. Herein, we engineer multi-functionally trunk-branch hierarchical heterostructures to address above limitations. Vertically aligned trunk-like CF scaffolds ensure superior through-plane heat transfer. Branch-like boron nitride (BN) networks optimize impedance matching by enhancing electrical insulation and consequently improve electromagnetic wave (EMW) absorption. Meanwhile, in situ BN networks interconnect CF scaffolds, extending bidirectional thermally conductive and EMW propagation paths. At only 20.17 vol% filler, the composite exhibits a through-plane thermal conductivity of 57.96 W·m −1 ·K −1 (specific thermal conductivity enhancement of 1431.62 %·(vol%) −1 ) and an in-plane thermal conductivity of 2.93 W·m −1 ·K −1 , together with excellent electrical insulation and absorption-dominated EMI shielding, addressing the challenge of thermal-electrical-electromagnetic coupling for next-generation electronics.

Pre-modification-free in-situ alkaline activation triggers spontaneous interfacial reconstruction between aramid and BN nanofibers. • Leaf-vein-inspired anisotropic nanocomposites establish vertical phonon highways via single-bottom directional cryogenic ice-templating. • Multi-scale capillary micro-confinement yields 1.12 W/(m·K) out-of-plane thermal conductivity and anti-dripping fire-shielding boundaries. The aggressive implementation of fast charging protocols in high-energy-density lithium-ion batteries severely intensifies internal Joule heating, triggering a hazardous electro-thermal-fire trilemma. Traditional organic phase-change materials (PCMs) offer an attractive energy-free cooling route but suffer from low thermal conductivity, liquid leakage, flammability, and poor electrical insulation. Herein, a leaf-vein-inspired anisotropic phase-change composite material (CPCM) is fabricated via an elegant, pre-modification-free in-situ alkaline activation and directional ice-templating strategy. By leveraging the residual nucleophilic hydroxyl ions natively dwelling within the strongly alkaline aramid nanofiber (ANF) slurry, the unpassivated edge defects of pristine boron nitride nanofibers (BNNFs) undergo a spontaneous interfacial chemical reconstruction. This in-situ reaction matures an extensive hydrogen-bonding network and mechanical interlocking with neighboring ANF backbones, structurally locking them into highly aligned, vertical lamellar cell walls. Benefiting from continuous vertical phonon highways, the engineered CPCM delivers an outstanding out-of-plane thermal conductivity of 1.12 W/(m·K) while preserving a premium latent heat density of 216.9 J/g with an elite cycling enthalpy retention of 96.58% across 400 continuous thermal iterations. Furthermore, the robust aerogel framework confers exceptional shape-stabilization, reliable electrical isolation (12.47 MΩ), and advanced anti-dripping structural integrity that effectively prevents hazardous flaming liquid runoff and pool fires during aggressive thermal matrix decomposition. When evaluated under a continuous 2C constant-current rapid-charging protocol for 1800 s, the dynamic synergy between accelerated directional heat conduction and large-capacity latent heat buffering successfully shunts intense internal heat flux outward, pinning the battery contact interface temperature at 34.3 °C with a peak regulation efficiency of 69.2%.

Driven by the practical demand for industrial-scale alkaline seawater electrolysis, chloride-induced corrosion and insufficient stability at high current densities remain critical challenges. Herein, a quinary NiFeCoAlSm high-entropy alloy (HEA) was synthesized by electrodeposition, followed by selective anodic dealuminization for 60 min to obtain a chloride-resistant bifunctional HEA electrocatalyst. The partial dealuminization process regulates the electronic structure and induces a dynamic hydroxyl-rich interface. Density functional theory (DFT) calculations reveal optimized OH − adsorption and suppressed Cl − adsorption on the reconstructed surface. Sm further strengthens the metal-hydroxyl (M OH) structure and stabilizes the catalytic interface. In alkaline seawater, the catalyst delivers an oxygen evolution reaction (OER) overpotential of 356 mV at 500 mA cm −2 and operates stably for over 1000 h, while achieving stable hydrogen evolution reaction (HER) performance at 1000 mA cm −2 for over 100 h. Anion exchange membrane water electrolyzer (AEMWE) for seawater electrolysis assembled with this electrode reaches 500 mA cm −2 at 2.06 V with long-term durability. This work provides a strategy for developing efficient and corrosion-resistant catalysts for industrial-scale seawater electrolysis.

In this work, a series of near-infrared persistent luminescent phosphors CaSnO 3 :Bi,xMg 2 + were prepared via Mg 2+ co-doping, and the effects of Mg²⁺ doping on the structure, luminescence properties, Bi valence state, and defects of the phosphors were systematically studied. The results show that at low doping concentrations, Mg²⁺ primarily enters the CaSnO 3 lattice in an interstitial manner, leading to lattice expansion. The interstitial incorporation of Mg²⁺ introduces positive charges, which promotes the reduction of Bi³ ⁺ to Bi²⁺, thereby increasing the concentration of Bi²⁺ and enhancing the near-infrared photoluminescence efficiency of the phosphors. Moreover, Mg²⁺ codoping modified the defect distribution in the phosphor, which further enhances the near-infrared persistent luminescence intensity. Under the optimal Mg 2+ doping concentration, the photoluminescence intensity of the phosphor increased by 0.8 times, and the initial persistent luminescence brightness improved by 6.3 times compared to the Bi singly-doped sample. This study not only provides a new near-infrared persistent luminescent phosphor but also offers a novel strategy for regulating the valence state of Bi ions through interstitial codoping to prepare Bi 2+ -based near-infrared persistent phosphors.

Carbon dots (CDs) have emerged as promising room-temperature phosphorescence (RTP) materials for advanced anti-counterfeiting and encryption applications owing to their tunable emission and favorable biocompatibility. However, the simultaneous realization of multicolor phosphorescence, long lifetime, and dynamic color modulation within a single CDs-based system remains a significant challenge. Herein, a boric acid-crosslinked and silane-confined CDs system was constructed to investigate the roles of rigid-network confinement and the rhodamine B (RhB)-regulated phosphorescence Förster resonance energy transfer (P-FRET) in governing dynamic multicolor afterglow. Compared with the conventional aminopropyl silane (APTES)-derived network, the long-chain diamine silane (DAMO)-derived network provided additional amino sites and a rigid-flexible confinement environment, which enhanced n–π* transition processes and promoted intersystem crossing, thereby extending the phosphorescence lifetime from 106.37 to 448.87 ms. Phosphorescence spectroscopic analysis revealed that increasing the RhB content introduced low-energy acceptor centers, which enhanced the P-FRET process from CDs to RhB-related acceptors and enabled tunable afterglow emission from blue (480 nm) to red (595 nm). The shortened donor lifetime, time-resolved emission evolution, and reduced energy gap revealed by density functional theory (DFT) calculations collectively supported the T 1 -S 1 P-FRET process from CD donors to RhB related acceptors. The resulting time-dependent afterglow color evolution was further demonstrated in dynamic digital encryption, multicolor QR codes, and time-resolved logic-gate anti-counterfeiting. This work provides a rational strategy for designing dynamic CDs-based RTP materials through rigid-network confinement and energy-transfer engineering.

2D MXene synergistically combines with biochar fibers to construct a porous 3D conductive network. • Ceramic aerogels possess superior microwave absorption capabilities coupled with structural stability. • A synergistic attenuation mechanism dielectric loss, magnetic loss, polarization, as well as multiple refraction and scattering is achieved. • An ultra-strong reflection loss of −60.1 dB is achieved at a thickness of 2.9 mm. Developing efficient electromagnetic wave absorbing materials capable of adapting to complex environments is of significant importance for advanced radar and electronic systems. Here, highly conductive MXene nanosheets are introduced into the biomass macromolecule bacterial cellulose (BC), and a BC/MXene (BM) hybrid scaffold with a honeycomb-like structure was prepared via directional freeze-drying. Subsequently, the SiBCOFe precursor was combined with the BM scaffold using a liquid-phase infiltration method, yielding BM/SiBCOFe ceramic aerogels. The results show that the conductive network formed by pyrolyzed BC-derived biomass carbon synergistically with MXene enhances the dielectric loss capability of the aerogel. Meanwhile, the heterostructures in situ generated on the surface of the BM from the precursor effectively improve the interfacial polarization effect and mechanical properties of the aerogel. Fe doping not only enhances magnetic loss but also optimizes impedance matching, ultimately achieving dual improvement in microstructure design and electromagnetic wave absorption performance. The BM/SiBCOFe ceramic aerogels exhibits excellent electromagnetic wave absorption performance: at a matching thickness of only 2.9 mm, the minimum reflection loss ( RL min ) reaches −60.1 dB, with an effective absorption bandwidth (EAB) of 4.6 GHz. The aerogel also exhibits excellent thermal and structural stability, making it an efficient electromagnetic wave absorbing material suitable for extreme environments.
