Cryo-Gel autonomously self-heals mechanical damage at −20 °C using only fluidic water molecules without external stimuli. • Cryo-Gel delays frost formation by 20-fold and ice accretion by 2.5-fold compared to uncoated surfaces at −45 °C. • Self-healing arises from reversible borate ester bonds, hydrogen bonds, and electrostatic interactions. • The coating restores transparency and anti-icing function after 350-μm scratches and 1,000 Taber abrasion cycles. • Global energy modeling predicts a net annual gain of 1.833 TWh if the Cryo-Gels are applied in frost-prone regions. The functional failure of anti-icing surfaces under mechanical damages in frigid environments is a critical, yet unsolved, challenge, as conventional self-healing mechanisms are inoperative by freezing. Here, we report a Cryo-Gel material, which autonomously repairs damage at −20 °C, driven solely by fluidic water molecules. This material is a zwitterionic hydrogel network integrating dynamic non-covalent borate esters within a covalent framework. It achieves a synergistic mechanical robustness and rapid bond reconfiguration at subzero temperatures, enabling water-triggered self-healing upon rinsing, defrosting, or rainfall. A single defrosting cycle is sufficient to heal the abraded Cryo-Gel and restore its exceptional anti-icing properties. At an extreme −45 °C, the Cryo-Gel delays frost formation by 20-fold and ice accretion by 2.5-fold compared to an uncoated surface. This work establishes a new principle for creating durable, adaptive ice-phobic materials capable of withstanding extreme conditions, overcoming the fundamental kinetic limitations that have plagued previous self-healing systems. Zwitterionic Cryo-Gels incorporate sulfobetaine methacrylate and 2-hydroxyethyl methacrylate through borate ester crosslinks. It achieves a synergistic mechanical robustness and rapid bond reconfiguration at subzero temperatures, enabling water-triggered self-healing upon rinsing, defrosting, or rainfall. A single defrosting cycle is sufficient to heal the abraded Cryo-Gel and restore its exceptional anti-icing properties, overcoming traditional self-healing coatings' low-temperature failure limitations.

The degradation of yttria-stabilized zirconia (YSZ) by silicate melts is a first order challenge to aviation. Yet the respective roles of dissolution thermodynamics and kinetics remain insufficiently distinguished. Here, in an effort to decouple these effects, three naturally-occurring (sand, dust, and volcanic ash) and five synthetic silicate melts were reacted with 8YSZ for up to 100 h. Corrosion depths were determined from the yttrium-depleted, mechanically softened, zone and quenched interfaces which largely preserve the high-temperature reaction state, were mapped. The naturally-occurring melts exhibited a complex behavior whereby ash melt penetrated rapidly at early stages but was arrested at 29 μm, whereas sand melt exhibited sustained penetration to 49 μm. The yttrium solubility index, calculated with the aid of compositional correlation models, exhibits a higher correlation with the terminal degradation depth than other, more conventional composition-based descriptors. The kinetic fragility index captures the transitions between continuous dissolution, crystallization-induced passivation, and penetration arrest. A two-parameter map based on these two parameters (thermodynamic capacity and kinetic fragility) can be used to illustrate and rationalize the degradation trajectories of silicate melts against 8YSZ. This approach provides a potential basis for screening corrosive deposits based on their composition-projected thermodynamic capacity and kinetic fragility for the customized regional design of more resistant ceramic systems.

Architectured ceramic absorbers are expected to simultaneously withstand mechanical loading and attenuate electromagnetic (EM) waves over a broad frequency range; however, achieving an optimized balance between structural integrity, impedance matching, and dielectric loss remains a major obstacle. In this work, a rhombus-like triply periodic minimal surface (TPMS) SiOC ceramic was fabricated and subsequently decorated with carbon nanowires (CNWs) along the ridge regions through an integrated process involving vat photopolymerization, polymer-derived ceramics (PDCs) conversion, chemical vapor deposition (CVD), and thermal treatment. This structural design establishes a hierarchical conductive–dielectric framework, where the TPMS geometry and ridge-oriented CNWs distribution collectively regulate mechanical and EM responses. The TPMS skeleton provides continuous load-transfer pathways while promoting EM wave penetration and multiple reflections, whereas the CNWs network introduces conductive channels and additional polarization interfaces to enhance EM dissipation. With a CNWs content of 3.95 wt%, the CNWs/SiOC ceramic delivers a minimum reflection loss (RL min ) of −54.66 dB and an effective absorption bandwidth (EAB) of 6.9 GHz at 3.35 mm. CST-based EM simulations confirm that the CNWs/SiOC architecture maintains a favorable dielectric response from 4 to 18 GHz, supporting broadband attenuation. In addition to its absorption capability, the sample containing 7.75 wt% CNWs reaches a compressive strength of 21.84 MPa, indicating the contribution of the architectured ceramic framework and ridge-oriented CNWs reinforcement to mechanical robustness. The improved attenuation is associated mainly with localized electric-field enhancement near the ridges, conductive dissipation through the CNWs network, and polarization loss generated by heterogeneous interfaces. These findings demonstrate that the ridge-oriented CNWs modification of architectured SiOC ceramics provides an effective strategy for the integrated realization and simultaneous optimization of load-bearing capability and broadband EM wave absorption.

Aiming at the urgent demand for multifunctional materials integrating thermal protection, stealth performance and load-bearing capacity in the field of next-generation hypersonic aircraft, this study develops a facile, template-free self-expansion foaming route to fabricate carbon fiber-reinforced porous (Hf, Zr, Ti)C medium-entropy ceramics, denoted as C f /(Hf, Zr, Ti)C (HZT). The influence of carbon fiber content (0–10 wt%) on the microstructure, thermophysical properties, mechanical performance, and electromagnetic wave absorption characteristics is systematically investigated. The synergistic mechanism among lattice distortion-induced polarization enhancement, porous structure-mediated multiple scattering, and carbon fiber-constructed conductive networks is elucidated, which effectively breaks the inherent trade-off between thermal insulation, mechanical strength, and microwave absorption in conventional porous ultra-high temperature ceramics. The sample with 6 wt% carbon fiber (HZT-06) possesses a porosity of 70.2% and a low density of 0.67 g/cm 3 . It exhibits a room-temperature thermal conductivity of 0.253 W m −1 K −1 , exceptional broadband microwave absorption with a minimum reflection loss (RLmin) of −59.69 dB and an effective absorption bandwidth (EAB, RL ≤ −10 dB) of 6.32 GHz at a matching thickness of 2.3 mm, and a high compressive strength of 49.62 MPa. This work realizes the multifunctional integration of low thermal conductivity, high load-bearing capacity and strong broadband microwave absorption at room temperature, and provides promising design strategies and fundamental data support for the development of advanced multifunctional thermal protection materials for hypersonic vehicles.

A novel near-infrared-responsive Sn-PHI has been developed. • Revealing the microscopic mechanism of the Lewis acid dilution effect for the first time. • Breaking the trade-off between broad spectrum absorption and high crystallinity. Tin poly(heptazine imide) shows superior light absorption over traditional alkali/alkaline earth metal counterparts. Tin(II) chloride (SnCl 2 ) is a convenient tin source but its strong Lewis acidity introduces structural defects that cause non-radiative recombination of photogenerated carriers. To address this issue, we dilute the Lewis acidity of SnCl 2 using five types of chloride salts. Taking LiCl as an example, molecular dynamics simulations confirm that the introduction of LiCl transforms the coordination environment of Sn 2 + from N-dominated to Cl - -dominated, reducing the Sn–N coordination number, thereby validating the Lewis acidity dilution effect. Experimentally, appropriate LiCl addition buffers SnCl 2 Lewis acidity, suppresses excessive and deep nitrogen vacancies, and thus significantly suppresses non-radiative recombination. This Lewis acidity dilution strategy resolves the contradiction between framework integrity and broadband light absorption, paving the way for novel crystalline carbon nitride photocatalysts with broad-spectrum response.

Cellulose has garnered widespread attention in the field of triboelectric nanogenerators (TENGs) due to its unique properties. However, constrained by the inherent characteristics of the material, the application of cellulose in TENGs is mostly limited to positive triboelectric materials. In this study, a TEMPO-oxidized nanocellulose (TOCN) aerogel film modified with polycarboxyl silicone oil was successfully prepared and utilized as a cellulose-based negative triboelectric material. By integrating a calcium copper titanate (CCTO)-doped, cross-linked amine-modified TOCN composite aerogel film, a cellulose-dominant TENG device was successfully fabricated, achieving an output voltage of up to 12.5 V. In addition, TOCN was employed as a reinforcing filler for PVDF-based negative triboelectric materials. After undergoing further surface roughening or stretching treatments, the composite material achieved an output voltage of 90 V, exhibiting excellent cycling stability, retaining 99.3 % of its initial output voltage after 5000 continuous operating cycles. This study provides valuable insights into the development of TENG devices based on renewable cellulose-derived components, offering new strategies for constructing high-performance cellulose-dominant TENGs.

Flux-free T-FPN enables ceramifiable silicone rubber at low filler loading. • ALSR/T-FPN4 achieves UL-94 V-0, 34.7% LOI, and lower heat release. • The composite passes 4.5 kV tracking with only 0.26% erosion after 6 h. • Hindered amine groups quench radicals and suppress backbone degradation. • Confined cross-linking forms a dense SiOC barrier against heat and arcs. Ceramifiable silicone rubber (SR) is promising for electrical insulation and fire-safety applications, but conventional low-melting-point fluxes often compromise flame retardancy and mechanical performance. Herein, a flux-free strategy (without conventional low-melting-point fluxes) is proposed for addition-cure liquid silicone rubber (ALSR) composites by surface-modifying fluorophlogopite nanosheets with a hindered amine-functionalized silane (T-FPN). Incorporating 4 phr T-FPN simultaneously improved the fire safety, tracking resistance, and mechanical properties of ALSR. Among the T-FPN loadings from 1 to 5 phr, ALSR/T-FPN4 exhibited the best overall performance. It achieved a limiting oxygen index (LOI) of 34.7% and a UL-94 V-0 rating, with peak heat release rate and total heat release reduced by 37.6% and 22.2%, respectively. It passed the 4.5 kV inclined-plane test with an erosion rate of 0.26% after 6 h. The improvement arises from a synergistic mechanism: well-dispersed FPN nanosheets restricted heat and mass transfer, while the hindered amine functionality provided oxygen-centered radical-scavenging capability and helped suppress oxidative degradation of the SR backbone. Meanwhile, confined interlaminar spaces favored Pt-assisted in situ cross-linking of preserved siloxane chains, forming a compact SiOC ceramic layer that shielded the matrix from heat and high-voltage arc erosion. This work offers an efficient route to fire-safe and tracking-resistant silicone rubber. Download: Download high-res image (177KB) Download: Download full-size image

Inorganic luminescent materials play a critical role in the fields of multimodal anti-counterfeiting. Although integrating multiple luminescence modes into a single matrix is considered a feasible strategy, it still faces significant challenges such as the regulation and identification of trap levels. Herein, Ba 0.75 Al 11 O 17.25 :Eu 2+ ,Yb 3+ ,Er 3+ phosphors integrating multiple luminescence modes, including afterglow, up-conversion luminescence (UCL), photo-stimulated luminescence (PSL), and thermoluminescence (TL) were developed. Importantly, the introduction of the Yb 3+ /Er 3+ ion pair not only suppresses the concentration of shallow traps but also induces the formation of numerous deep traps (1.62 eV), which are essential for multimodal luminescence and enhance the thermal stability of the luminescence. Furthermore, through comprehensive analysis of density functional theory (DFT) calculation, TL curves, electron paramagnetic resonance (EPR) and X-ray photoelectron spectroscopy (XPS), it is confirmed that the trap levels primarily originate from oxygen vacancies and interstitial aluminum. Finally, a highly stable flexible film was fabricated, whose emission intensity and color can be controlled by external light/thermal stimuli, and its applications in anti-counterfeiting and information encryption are demonstrated. This work facilitates the research on advanced luminescent materials and traps regulation mechanisms.

Ultraviolet (UV) photocuring imprinting technology enables the efficient and high-fidelity fabrication of silica glass micro/nanostructures under room-temperature and low-pressure conditions, showing unique advantages for the manufacturing of complex silica glass optical components. However, thick-walled silica glass components are highly prone to cracking during the forming process, which severely restricts the extension of this technology to the fabrication and application of thick-walled silica glass components. To address this issue, this study first elucidates the physical origin of internal-stress instability in thick-walled photocuring systems. A light-thermal synergistic regulation manufacturing strategy is then proposed innovatively. The strategy mitigates stress accumulation from three dimensions. The photoinitiator concentration is optimized to balance the photoinitiation efficiency and penetration depth. A sequential bidirectional exposure process assisted by a customized light shield is introduced to flatten the optical energy gradient. A dynamic preheating treatment at 60 °C is applied to broaden the stress-relaxation window and alleviate the polymerization exotherm peak. The experimental results show that this strategy successfully produces crack-free green bodies with thickness up to 7 mm. After thermal treatment, dense and transparent silica glass components were obtained, exhibiting a visible-light transmittance of 92% and a nearly uniform through-thickness Vickers hardness of approximately 1205 HV, both comparable to those of commercial fused silica glass. The synergistic strategy is further extended to the fabrication of a near-square-aperture lens array, achieving nearly isotropic shrinkage of the array structure and high-fidelity transfer of the lens surface profile. The fabricated lens arrays exhibit excellent beam homogenization and focusing imaging performance. This study overcomes the thickness limitation of ultraviolet photocuring imprinting technology for silica glass fabrication and provides a feasible route for the structure-function integrated manufacturing of silica glass components with both thick bulk features and complex microscopic surface precision.

C@MoS 2 @Ag 2 S heterojunction nanozyme was constructed. • C@MoS 2 @Ag 2 S presented exceptional peroxidase-like activity. • p-nitrophenol was efficiently degraded by C@MoS 2 @Ag 2 S through activating H 2 O 2 and PDS. In this study, a carbon-coated MoS 2 @Ag 2 S (C@MoS 2 @Ag 2 S) heterojunction nanozyme with superior peroxidase-like activity is prepared via heterojunction pre-construction followed by carbonization. The kinetic parameters toward H 2 O 2 are determined to be K m = 1.02 mM and V max = 38.08 × 10 −8 M·s −1 , and toward 3,3′,5,5′-tetramethylbenzidine (TMB) are K m = 0.14 mM and V max = 60.35 × 10 −8 M·s −1 . Notably, its affinity for H 2 O 2 is substantially higher than that of natural horseradish peroxidase (HRP, K m = 3.7 mM), and the catalytic efficiency (V max ) is also superior. Enhanced performance stems from three-component synergy improving electron transport, charge separation, and ROS generation. Through synergistically activating persulfate (PDS) and H 2 O 2 , SO 4 • ⁻ , •OH, and 1 O 2 are generated, which collectively degrade PNP, achieving 90% removal in 40 min. This study offers theoretical guidance for the controllable synthesis of biomass-derived carbon/metal sulfide heterojunction nanozyme and the design of dual-oxidant synergistic activation systems for degradation of organic pollutants.

Hierarchical HZSM-5 with integrated micro–mesopore structure is promising for boosting light olefin yield in light paraffin catalytic cracking, yet conventional alkali etching creates disordered large mesopores and rough crystal surfaces that degrade light olefin selectivity. Herein, this work adopts NaHCO 3 –TPAOH composite alkali treatment and pos-surface silanization treatment were used to regulate the micro-mesopore spatial distribution of hierarchical HZSM-5, for investigating the re-distribute of the hierarchical HZSM-5 and the effects of pore structure and its spatial arrangement on product selectivity. It was found TPA + in composite alkali system possesses large steric hindrance, which inhibits excessive local OH - corrosion, and avoids the formation of irregular large defective mesopores. On the optimized catalyst, the selectivity of light olefins is elevated by 8.7%. After surface silanization of zeolite, precisely passivates external acidic sites without blocking internal micropore channels, concentrating mesopores inside the zeolite framework. This structure greatly promotes the monomolecular cracking pathway of alkanes and achieves an improvement in ethylene production. This study clarifies the regulatory mechanism of spatially differentiated mesopores in HZSM-5 catalysts on the n-hexane catalytic pyrolysis reaction and their modulation effect on light olefin selectivity. It deepens the fundamental understanding of the structure-performance correlation of hierarchical porous zeolites and provides reliable guidance for the rational design and targeted fabrication of high-efficiency pyrolysis catalysts.

Thermally conductive composites are witnessing expanding applications in electronics, energy and aerospace sectors. However, the development of eco-friendly, durable and high-performance thermally conductive materials remains a key challenge. To address this challenge, we rationally designed and fabricated a cardanol-derived non-isocyanate polyurethane (NIPU). Boron nitride nanosheets (BNNSs) and diphenyl chlorophosphate (DCP) were incorporated into the NIPU matrix to improve its thermal conductivity and flame-retardant performance. Moreover, dynamic disulfide bonds were rationally incorporated into the system, endowing the NIPU composites with efficient and reliable self-healing capabilities. Consequently, benefiting from the continuous thermally conductive pathways established by BNNSs, the 20% NIPU-2 N sample exhibited a striking 270% enhancement in through-plane thermal conductivity at a BNNSs loading of 20 wt%, reaching a final thermal conductivity of 1 W·m −1 ·K −1 . Additionally, the 20% NIPU-2 N achieved efficient self-healing at 100 °C within 3 h, with a tensile-strength recovery of 95.5%, and attained a V-0 flame retardancy rating. This fabrication strategy, leveraging the nano-reinforcing effect of BNNSs, offers a scalable approach that integrates green synthesis, efficient thermal management, and prolonged service life, demonstrating outstanding application potential in flexible printed circuits and wearable sensors.
