However, conventional ionogels suffer from electrolyte leakage, interfacial instability, and susceptibility to external disturbances, leading to compromised sensing fidelity. Herein, a Janus-adhesive ionogel is engineered via a stepwise polymerization strategy to integrate asymmetric adhesion with stable ionic conduction. The adhesive layer ensures conformal and durable skin-electrode coupling through cation-π interactions and hydrogen bonding, while the non-adhesive layer provides mechanical protection and environmental insulation, enabling functional decoupling. The ionogel exhibits excellent mechanical performance (fracture energy of 17.70 kJ m<sup>−2</sup> and toughness of 6.39 MJ m<sup>−3</sup>), stable ionic conductivity (0.55 mS cm<sup>−1</sup>), and durable adhesion. Benefiting from its asymmetric architecture, the device achieves low interfacial impedance and suppresses motion artifacts and interference. It enables high-fidelity acquisition of electrophysiological signals (sEMG, ECG) with enhanced signal-to-noise ratios compared to commercial electrodes, as well as precise detection of subtle biomechanical motions. The results establish a generalizable strategy for improving interfacial stability and signal fidelity in wearable ionotronics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"24 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147726430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work successfully synthesized CdS-T-3 material featuring a high-density twin distribution. Under the influence of the twin structure, CdS-T not only enhanced photocatalytic performance but also synergistically improved the selectivity of multiple carbon products. The CO yield of CdS-T-3 (371.804 µmol·g<sup>−1</sup>·h<sup>−1</sup>) was 1.891 times and 1.398 times that of CdS-T-1 and CdS-T-5, respectively. Simultaneously, the C<sub>2</sub>H<sub>4</sub> yield of CdS-T-3 (195.988 µmol·g<sup>−1</sup>·h<sup>−1</sup>) was 5.385 and 3.043 times that of CdS-T-1 and CdS-T-5, respectively. This is attributed to the self-generated electric field at the twin interfaces, which not only effectively promotes electron transfer but also significantly suppresses electron–hole recombination. Consequently, electrons are efficiently utilized during the reduction process, enhancing photocatalytic CO<sub>2</sub> reduction performance. More importantly, the influence of twinning becomes more pronounced with increasing twinning density. This study analyzes the performance impact of twinning structures in photocatalytic CO<sub>2</sub> reduction from two perspectives: charge transfer behavior at twinning interfaces and twinning density regulation, while exploring its underlying mechanisms.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"21 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving high multifunctional efficiency remains challenging, as lithium-ion transport in carbon fibers is restricted at high current densities, resulting in poor rate capability and significantly decreased reversible capacity. To solve this problem, this work develops an integrated structural anode of carbon/carbon composite (C/C) for both structural support and energy storage. Atomic force microscopy combined with in situ characterization techniques, including in situ Fiber Bragg Grating sensing, in situ electrochemical impedance spectroscopy, and Operando Raman spectroscopy, reveals that the unique “onion-skin” buffering structure in C/C significantly enhances the mechano-electrochemical properties of the electrode through a synergistic “shielding-channeling” mechanism. The all-fiber structural lithium-ion battery with commercial organic electrolyte demonstrates a high energy density of 60 Wh kg<sup>−1</sup> with excellent power density (65 W kg<sup>−1</sup>) and cycling stability. Remarkably, it achieves a record-high near-unity multifunctional efficiency (0.96), while maintaining remarkable electrochemical stability under tensile, bending and out-of-plane compressive conditions, demonstrating great potential for applications in aerospace systems, intelligent transportation, and next-generation lightweight structural energy storage technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"135 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike conventional metallic implants, which frequently exhibit poor biocompatibility, high infection risks, and mechanical mismatches with host tissues—leading to complications like implant failure and revision surgeries—BMHEAs leverage their multi-principal element composition to integrate superior properties such as enhanced biocompatibility, mechanical strength, antimicrobial activity, and controlled degradation. For instance, CoCrFeNiMn-based BMHEAs have demonstrated exceptional corrosion resistance and osteogenic promotion in vitro, outperforming titanium alloys by reducing bacterial adhesion by up to 90% while fostering better cell proliferation. Similarly, TiZrHfNbTa BMHEAs exhibit tunable Young's modulus close to that of cortical bone (10–30 GPa), minimizing stress shielding and improving long-term osseointegration, as evidenced by animal studies showing accelerated bone healing compared to stainless steel implants. These examples underscore BMHEAs’ immense potential to address clinical challenges, including infection control and tissue integration. Despite ongoing hurdles like predictive design and in vivo validation, the rapid progress in computational screening positions BMHEAs as transformative candidates for next-generation implants, promising enhanced patient outcomes and reduced healthcare burdens.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"12 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147726574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, a specific silver paste formulation with low corrosivity and excellent rheological properties enables the formation of low-contact resistance.

In this study, we designed three Y6-based photothermal molecules with distinct alkyl chain architectures: Y6-0 (no alkyl chain), Y6-nC11 (linear), and Y6-iC11 (branched). Biomimetic nanoparticles incorporating these molecules were constructed (DP@Y6-0, DP@Y6-nC11, and DP@Y6-iC11). The structure–property relationships between the alkyl chain structure, photothermal performance, and storage stability were investigated. Molecules with alkyl chain modifications (Y6-nC11 and Y6-iC11) were found to enhance liposome-binding affinity via hydrophobic interactions. Long alkyl chains promoted more ordered molecular packing, branched side chains (compared to their linear counterparts), and disrupted <i>π–π</i> stacking distances, thereby diminishing photothermal performance. Therefore, the DP@Y6-nC11 nanoparticles exhibited a more pronounced redshift in absorption and superior photothermal performance compared to DP@Y6-iC11. Furthermore, fusion with tumor cell membranes significantly enhanced the tumor-specific accumulation of these nanoparticles. Overall, M@DP@Y6-nC11 nanoparticles exhibited excellent photothermal therapeutic efficacy in personalized tumor-specific models.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"12 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147726450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we demonstrate that morphology-induced crystal phase modulation of ZrO<sub>2</sub> supports enables effective optimization of interfacial sites in Ni/ZrO<sub>2</sub> catalysts. By engineering cubic (Ni/ZrO<sub>2</sub>-C) and stellated (Ni/ZrO<sub>2</sub>-S) architectures, a metastable mixed-phase structure (54.8% monoclinic/37.3% tetragonal) is stabilized to achieve precise phase regulation. Systematic characterization reveals that this phase transformation strengthens metal–support interactions, improves Ni dispersion, and generates abundant oxygen vacancies. As a result, Ni/ZrO<sub>2</sub>-C achieves 95% ethanol conversion with lower by-product formation and exhibits exceptional stability, with a 50% lower deactivation rate (0.13% h<sup>−1</sup>) than Ni/ZrO<sub>2</sub>-S (0.26% h<sup>−1</sup>). The enhanced performance is attributed to improved surface basicity and more efficient coke gasification facilitated by interfacial oxygen vacancies. ​Theoretical calculations further confirm kinetically favorable pathways with reduced activation barriers, particularly for carbon oxidation, accounting for the observed 3.2-fold higher activity of Ni/ZrO<sub>2</sub>-C.

In practical engineering systems, the realization of macroscale superlubricity is often accompanied by irreversible material loss, leading to increased wear rates and reduced service lifetimes. To address this challenge, a supramolecular composite lubricant film composed of citric acid (CA)–chitosan (CS) functionalized Ti <jats:sub>3</jats:sub> C <jats:sub>2</jats:sub> T <jats:sub>x</jats:sub> MXene (CA–CS@MXene) was fabricated. This CA–CS@MXene film exhibits macroscale superlubricity (friction coefficient ∼0.006) and a near‐zero wear rate under 50% relative humidity. This extraordinary behavior arises from a humidity‐driven transition of interlayer interactions, where static strong hydrogen bonds among Ti <jats:sub>3</jats:sub> C <jats:sub>2</jats:sub> T <jats:sub>x</jats:sub> MXene nanosheets are converted into dynamic, weak, and rapidly exchangeable ones. Such a transformation lowers the interlayer sliding energy barrier and enhances hydrogen‐bond‐mediated structural reconstruction, enabling real‐time self‐healing under frictional stress. This work offers new insights into the design of solid lubricants that combine macroscale superlubricity and self‐healing capabilities, and demonstrates broad applicability in representative mechanical components such as planar bearings, spur gears, spherical bearing inner rings, and flexible rubber substrates.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"16 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147719826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
