Herein, an aqueous electrochemical capacitor for wide-voltage and ultrafast-response filtering is developed using the boron-doped diamond electrodes that feature both the ultra-wide potential window of 2.93 V and vertical-oriented nanoarray architecture. This capacitor exhibits a wide voltage window up to 2.5 V larger than those of reported aqueous filtering capacitors to date and a high-frequency response capability with a characteristic frequency f0 = 3338 Hz, as well as a phase angle of −80.4° and a high specific energy density of 365.6 µFV2 cm−2 at 120 Hz. These superior properties enable effective ripple smoothing of rectified AC signals with complex waveforms, high frequency (60–1000 Hz), and large voltage amplitudes up to 5 V.

Using first-principles calculations and micromagnetic simulations, this study have discovered that in the LaCl2/In2S3, LaBr2/In2Se3, and LaCl2/In2Se3 heterostructures, the ferroelectric (FE) polarization reversal is able to manipulate the magnetic frustration in the ferromagnetic (FM) monolayer, thus allowing the creation and annihilation of nontrivial topological spin textures. In particular, in the LaI2/In2Te3 heterostructure, the FE polarization reversal can alter the bimeron morphology. A semiconductor-to-half-metal transition has also been observed in the FM monolayer, mainly due to interfacial charge transfer, making electrical-current-driven motion possible. The dynamics of bimeron clusters has been thus investigated in the half-metal under 100% spin-polarized electrical current and the behavior of skyrmions with large topological numbers under magnetic fields. These results indicate that the electrically-tunable topological spin textures in multiferroic heterostructures have potential applications in low-power and nonvolatile information technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"6 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269270","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}

Common strategies of introducing additional separators or cross-linking can significantly increase the manufacturing complexity of SPEs, thus limiting their commercialization. Herein, inspired by the musculoskeletal structure, a “soft-hard synergy” enhanced SPE (named PPH-SPE) is successfully designed and manufactured by a simple one-step in situ microphase separation strategy for high-temperature lithium–metal batteries. In the bicontinuous PPH-SPE, the “soft” polyphosphazene liquid polymer electrolyte (PPZ-LPE) phase provides excellent electrochemical properties, interfacial compatibility, and high-temperature stable Li3N/Li3PO4-rich hybrid interfaces. PVDF-HFP crystals are skillfully used to build a 3D continuous, high-strength (0.32 ± 0.02 MPa at 90 °C), thermotolerant “hard” skeleton. In the synergy of two phases, Li//Li cell can maintain continuous electrodeposition over 4500 h of the plating/stripping process at 0.25 mA cm−2 and 0.25 mAh cm−2. Furthermore, LiFePO4//Li coin and pouch cells achieve an ultra-long lifetime of over 1000 (1 C) and 1800 (0.5 C) cycles at 90 °C, respectively.

By introducing solvents that weaken polymer-polymer interactions, glassy polymers can be converted into soft states. To obtain mechanical strength and ductility simultaneously, a supramolecular solvent-mediated polymeric gel with high toughness and adhesion is proposed by the synergistic effect of supramolecular solvent and polyacrylic acid. Polymerization of acrylic acid within the supramolecular solvent composed of β-cyclodextrin and citric acid results in a macroscopically homogeneous system with in-situ microphase separation: the polymer-rich phase exhibits compelling high elastic behavior under tensile strain, and the supramolecular solvent-rich phase weakens interchain interactions within polymer chains and establishes a robust solvent-polymer interface interaction, improving the toughness. The supramolecular solvent-mediated polymeric gels exhibit high toughness (208 MJ m−3), high stretchability (≈3400%), self-healing, and recyclability. The dynamic feature and strong affinity of supramolecular solvent would enable them to adaptively wet rough surfaces and form topological cross–linking for adhesion, thereby improving the interfacial toughness. Reversible adhesion could be realized by moisture treatment. The application of adaptive grasping soft robotics with in-situ repair capability is also demonstrated. This work provides a novel and simple strategy for the fabrication of tough gels with excellent adhesive performance.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"102 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144260762","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 study implements an ultrasound (US) responsive 2D Bi2WO6 nanosheets (BWO NSs) as sonosensitizers to generate reactive oxygen species (ROS), resulting in sonodynamic broad-spectrum bacterial elimination. Notably, lanthanide Ytterbium ions are introduced (BWO-x%Yb NSs) to boost the generation of ROS, leading to an enhanced antibacterial effect. The RNA sequencing further reveals the underlying antibacterial mechanism, wherein ROS induces lipid oxidation in bacterial cell membranes and deterioration of membrane integrity, ultimately leading to cellular death. In vitro experiments verify that BWO-x%Yb NSs sonosensitizers attain 100% elimination on Methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli) under US irradiation, demonstrating a broad-spectrum bactericidal ability. Furthermore, to improve the biocompatibility for in vivo SDT, BWO-x%Yb NSs are integrated with hydrogel, serving as a sonosensitizer-hydrogel platform. This platform expedites the healing process of MRSA-infected wounds under ultrasonic stimulation and reduces the wound area by 75% in 10 Days.

These biomimetic scaffolds are designed to modulate the mechanotransduction pathways of neural stem cells (NSCs), thereby enhancing neurogenesis and guiding neuronal differentiation. They also influence essential cellular processes such as adhesion, cytoskeletal alignment, morphological polarization, and gene regulation. This review systematically evaluates current strategies for optimizing topographical designs, emphasizing their role in promoting neurite outgrowth, axonal guidance, and synaptic reformation. The mechanisms are elucidated by which scaffold topographies regulate NSC fate decisions through mechanobiological signaling and interactions with the extracellular matrix. Additionally, critical barriers are analyzed for clinical translation, including the precision fabrication of tunable architectures, the scalability of novel materials, and strategies to mitigate glial scar formation.

The design of semiconducting layers with tunable mechanical properties is crucial to improving the performance and reliability of plastic electronics, particularly for flexible and stretchable devices. Here, a method is demonstrated for systematically controlling the persistence length, allowing improvement of the mechanical properties of a single conjugated polymer system without the need for complex chemical modifications to the rigid backbone. The effects of plasticizing molecular additives (PMAs) on the rigidity of conjugated chains are thoroughly investigated through persistence length analysis. Solution-based small-angle neutron scattering reveals how different PMAs influence the persistence length of the benchmark rigid conjugated polymer PDPP2T-TT-OD. The mechanical, thermal, morphological, and electrical properties of PMA-blended films are evaluated under deformation. The results show that the mechanical modulus is primarily influenced by modification of the persistence length and the formation of uniformly entangled networks with smaller crystalline grains. The analysis suggests that the uniform distribution of PMAs in PDPP2T-TT-OD films, combined with physically crosslinked chains, significantly enhances thin film deformability. Notably, charge mobility remains stable even after stretching to 100% strain. These findings provide valuable insights into the design principles of PMA-blended conjugated polymer systems, offering a pathway for tailoring mechanical properties in future plastic electronics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"2 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144260653","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}
