By combining polyanionic and polycationic gels based on DES, synchronized contraction of the two yarn electrodes is achieved via selective ion intercalation and enables unipolar actuation in solid-state CNT yarn actuators. The studies on the electrochemical properties of the actuator show that the contractile stroke and the stroke-to-charge ratio increase as the amount of ionic units in the polymers increases. At high ionic monomer content, evidence of an early scan-rate-enhanced-stroke (SRES) effect can also be observed. The solid-state actuator reaches a contractile stroke of 2.25% under a 90 mN load and remains stable over 300 cycles in ambient conditions. Textile integration through inlaying preserves actuator functionality, achieving up to 3.4% strain, demonstrating excellent compatibility with smart wearable platforms. These results highlight the potential of DES-based gel coatings for the scalable development of unipolar, high-performance, and environmentally sustainable artificial muscles suitable for e-textiles, soft robotics, and prosthetics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"2 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183347","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}

Prussian blue analogues (PBAs), with their open framework and multi-electron redox capability, are promising candidates for NH4+ storage. However, their capacity is fundamentally limited by the electrochemically inert low-spin Fe (FeLS) sites, which contribute minimally to redox activity. In this work, it is demonstrated that the kinetic inactivity of FeLS is not intrinsic but can be partially unlocked through targeted defect engineering. The introduction of [Fe(CN)6]4− vacancies and coordinated water molecules significantly improves NH4+ diffusion and charge transfer, enabling the participation of FeLS in the electrochemical reaction. The resulting defect-rich FeHCF material (PB-0) achieves a high reversible capacity of 120 mAh g−1, exceeding conventional PBA benchmarks. Furthermore, by optimizing the electrolyte composition, the system delivers outstanding long-term cycling stability (96.4% capacity retention after 500 cycles) and excellent rate performance (82.4% capacity retention at 500 mA g−1). These results demonstrate how defect engineering can improve the performance of PBA-based electrodes for AAIBs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183346","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}

Inspired by the “for” loop function in computer programming, this work proposes a dynamic active site strategy to modulate “self-adaptive” adsorption of OH− to achieve a continuous urea-to-water electrolysis for the first time, with a highly selective switching from UOR to OER. Specifically, MoO42−-doped NiCo-based layered double hydroxide (NiCo-LDH-MO) is developed as the UOR/OER bifunctional catalyst through the hydrothermal doping and electrochemical reconstruction of Prussian blue analogs. With the aid of density functional theory (DFT) calculation and the in situ characterizations, it suggests that OH− is preferentially adsorbed on Co sites to generate CoOOH for UOR in the presence of urea, and then self-adaptively adsorbs on Ni sites to generate NiOOH for OER after the removal of urea. As a result, the reconstructed electrode exhibits remarkably low potentials of 1.27/1.36 V for UOR at 10/100 mA cm−2, respectively, and only 347 mV overpotential for OER at 100 mA cm−2.

However, incomplete coverage, poor uniformity, and insufficient stability of SAM films still hinder the large-scale industrial application of SAM-based HTLs in PSCs. Here, an interfacial hybrid engineering (IHE) strategy is proposed that incorporates a molecular suppressor, 4,4,4-tris(phosphoryl) triphenylmethane (PA), to regulate SAM assembly and optimize interfacial properties. PA effectively mitigates molecular aggregation of 2-(9H-carbazol-9-yl) ethylphosphonic acid (2PACz) through steric hindrance and chemical interactions, which ensures the homogeneous distribution, well-ordered assembly, and scale-up preparation of SAM molecules. Thereby, the perovskite/HTL interface exhibits improved energy level alignment, charge extraction efficiency, and defect passivation. The champion PCE of the PA-based small-area devices is 26.55%. Large-area modules incorporating PA exhibit record-breaking efficiencies of 22.81% (22.8 cm2) and 20.16% (750.5 cm2), representing the highest performance reported for single SAM-HTL layers in scalable PSCs. Additionally, PA-modified devices demonstrate remarkable operational stability under ISOS-D and ISOS-L testing conditions. This IHE strategy provides an effective and scalable solution for achieving uniform SAM deposition in large-area PSCs while simultaneously enhancing device efficiency and long-term durability, paving the way for the commercialization of SAM-based perovskite photovoltaics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"90 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145153595","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 type, depth, distribution, and density of these traps govern the release features and dynamics of charge carriers, and consequently dictate the wavelength, intensity, and duration of PersL. Despite extensive research on PersL, a comprehensive review specifically focusing on the role of defects is lacking. Herein, we provide an overview of the composition and mechanisms of PersL, followed by systematic explorations on the types of defects, common characterization methods, their impact on PersL performance, and defect engineering strategies for PersL optimization. After highlighting defect-guided design of persistent luminescent nanoparticles (PLNPs), advances in first-principles modeling of defects, and representative applications of PersL materials are summarized.

Centered on Fe2⁺/Fe3⁺ dynamic coordination, the binder incorporates control via the intricate and rigid rosin architecture and a hierarchy of distinct bonding mechanisms, thereby enhancing its capacity for both rapid energy dissipation and strain-triggered reinforcement. Sodium alginate serves as a continuous phase framework, reinforced by phosphorylated cellulose nanocrystals, conformation-locking segments of acrylic acid rosin, and a multivalent coordination network that enables this strain-triggered state transformation.

In this study, a ROS-scavenging polyurethane nano-decoys (NDs) modified with N-acetylneuraminic acid (sialic acid, SA) (PTSA) is developed for therapy of MI via convenient intravenous injection. Due to the high affinity of SA to macrophages, PTSA is better camouflaged to avoid fast immune clearance, allowing long-term retention in the damaged myocardium. The loaded nicorandil (NIC) could be faster released in response to ROS environment, which in turn scavenged ROS and alleviated the inflammation. The NIC@PTSA effectively inhibited abnormal mitochondrial function and apoptosis of cardiomyocytes in vitro. Under the synergistic effect of ROS-scavenging and NIC release, the function of endothelial cells is reprogrammed, promoting the process of vascularization.
