Photocatalytic oxygen reduction reaction (ORR) offers a sustainable method for producing oxygen, yet its efficiency is limited by poor charge separation and severe carrier recombination. Single-component photocatalysts suffer from sluggish carrier dynamics, while multi-energy-state systems frequently experience recombination at intermediate states. S-scheme heterojunction engineering offers an effective strategy to address these challenges by regulating interfacial charge transfer while preserving strong redox potentials. Here, we report the construction of an S-scheme photocatalyst by integrating a triazine-based covalent organic framework (COF) with sulfur-vacancy-rich Mn0.2Cd0.8S (Sv-MCS). This dual-functional design preserves both the intrinsic n→π* electronic transitions of the COF and defect-state absorption of Sv-MCS, delivering an exceptional H2O2 production rate of 5389.6 µmol·h-1·g-1 in pure water. Concurrently, the photostability of the catalyst is simultaneously enhanced. X-ray absorption fine-structural analysis confirms interfacial Cd-O coordination between Cd atoms and COF carbonyl groups. In situ spectroscopies combined with density functional theory elucidate a preferential two-electron ORR pathway, while femtosecond transient absorption spectroscopy confirms suppressed carrier recombination enabled by synergistic S-scheme charge transfer and interfacial chemical bonding. This work establishes design principles for multi-energy-state S-scheme photocatalysts and advances solar-driven H2O2 production toward artificial photosynthesis.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73326"},"PeriodicalIF":26.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831080","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}

Their diagnostic potential is immense, yet their heterogeneity poses persistent challenges for isolation and characterization, often leading to low yield, co-isolation of contaminants, and vesicle damage. Here, we present a thermoresponsive polymer-integrated plasmonic metasurface sensor that enables spatiotemporally controlled, label-free EV isolation. The metasurface, engineered by repurposing nanograted optical disks, was functionalized with poly(N-isopropylacrylamide) (PNIPAM) and anti-CD63 antibodies to achieve selective EV capture at physiological temperature and gentle release upon a minute thermal change near the polymer's lower critical solution temperature (∼35°C). Using MCF-7 and HEK-293-derived EVs as a proof-of-concept, the platform exhibited a dynamic detection range spanning three orders of magnitude. Release efficiency reached 87.03 ± 23.5%, while both nanoparticle tracking analysis (NTA) and fluorescent NTA (fNTA) revealed up to ∼100-fold increase in EV purity relative to the ultrafiltration process. Electron microscopy and Western blotting confirmed preserved vesicle morphology and marker expression. By integrating thermoresponsive chemistry with a cost-effective metasurface platform, this system offers a non-destructive, portable, and real-time solution for precise EV manipulation, advancing EV-focused biosensing and point-of-care strategies for liquid biopsy applications in the future.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e22964"},"PeriodicalIF":26.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831096","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}

The resulting iChon+hPDC assembloids exhibit intrinsic spatial organization, forming chondral- and osteo-like zones with an intermediate interface without exogenous scaffolds. In vitro characterization confirmed layered glycosaminoglycan-rich cartilage and collagen I-rich osteo-associated domains, with interface continuity emerging through self-directed matrix organization. Upon implantation into full-thickness osteochondral defects, iChon+hPDC assembloids promoted robust hyaline-like cartilage repair, supported subchondral bone formation with ongoing repair/remodeling, and partially reestablished collagen fiber anisotropy. Protein-level mapping further supported a surface-associated cartilage phenotype and remodeling-associated signatures in the deep compartment. Transcriptomic profiling revealed complementary biological programs, with iChon showing features suggestive of stable cartilage regulation and extracellular-matrix remodeling competence, and hPDC showing a transient hypertrophic program associated with endochondral ossification.

However, as increasing their energy densities with high-loading thick electrodes, the ion transport kinetics are usually limited during cycling. Here, asymmetric roll-ups of transition metal carbides (MXenes) are fabricated via a modified stiffness-mediated rolling-up strategy. Such asymmetric structure induces an electron concentration gradient along the axis of MXene roll-up, leading to a strong polarization electric field. Under the polarization, ionic transport conductance of the asymmetric MXene roll-up in various ions (e.g., H+, Li+, Na+, NH4 +, Zn2+, Mg2+, Al3+) is up to ∼102 µS, which is an order of magnitude higher than the constituent building blocks (∼101 µS). As a result, the film constructed from asymmetric MXene roll-up exhibits an ultrahigh rate capability of ∼400 F g-1 at 5000 mV s-1 and unique thickness-independent capacitive features. Moreover, the areal capacity of the 400-µm-thick MXene roll-up film with a high mass loading of ∼50 mg cm-2 is up to ∼26 F cm-2, outperforming the most reported materials.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73340"},"PeriodicalIF":26.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147855506","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, its industrial application at ampere-level current densities (ACDs) remains challenging. Conventional disordered gas-evolving electrode (GEE) scaffolds endow with sluggish bubble detachment kinetics and mechanical instability, preventing operation at high ACDs, while rational scaffold designs for accelerating bubble detachment remain rarely explored. Inspired by starfish scaffolds, we design and fabricate a biomimetic GEE with conical sieve-plate hole scaffolds via 3D printing. Combined COMSOL simulations and in situ bubble behavior analyses reveal that like the breath and mass exchange of starfish, the sieve plate optimizes bubble force balance to accelerate detachment, while the conical structure conducts bubbles rapidly into the electrolyte. Such starfish-inspired GEE design yields a 21-fold lower mass-transfer overpotential vs. current density slope than that of common flat round-hole scaffold. Consequently, champion lowest overpotentials of 159 and 430 mV among all the well-documented state-of-the-art GEEs are achieved at the ACD of 1000 mA cm-2 for HER and OER, respectively. Moreover, our starfish-inspired GEE sustains ACDs operation with ≈100% Faraday efficiency for over 150 h, demonstrating its potential for practical AWE applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73344"},"PeriodicalIF":26.8,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831119","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}

To address this challenge, we developed a synergistic fabrication strategy that integrates freeze-thawing, mechanical training, and solvent exchange to construct hierarchically structured hydrogels. The polyvinyl alcohol-based hydrogel that has been repeatedly freeze-thawed, was then immersed in a glycerol/water solvent containing ferric chloride and subjected to approximately 200 000 mechanical training cycles. The resulting hydrogel exhibited remarkable comprehensive properties, including a tensile strength of 9.38 MPa, a fracture energy of 187.5 kJ m-2, a fatigue threshold of 7850 J m-2, a conductivity of 0.64 S m-1, and excellent flexibility even at -80°C. Leveraging this multifunctionality, the hydrogel was further assembled into a strain sensor capable of precise, rapid monitoring of finger motion and was employed in a gesture-controlled drone system.
