However, existing systems often rely on mechanical water movement, liquid water supplementation, or high-humidity conditions, limiting their practical applications in fluctuating environments and wearables. Here, a self-gradient hydrogel-based moisture-induced electric generator (SHMEG) is reported, formed by the self-diffusion of pre-gel solution on carbon blacks loaded knitted fabric and a pair of sliver electrodes, which can maintain high performance and flexibility under various environments. The main driving source of SHMEG is the electric double-layer gradient formed at the hydrogel–carbon interface and the intrinsic properties of electrode. The SHMEG demonstrates a sustained voltage output of 0.75 V for 140 h and a current output of 15 µA at ≈75% RH under room temperature (≈25 °C). Benefitting from the high hygroscopicity, moisture retention, and temperature adaptability, SHMEG reliably delivers a stable electrical output of 0.5 V at 20% RH and 0.7 V at −10 °C. Moreover, SHMEG demonstrates versatility by powering small electronics and functioning as a strain sensor with up to 300% stretchability. This work represents a significant advance in moisture-induced energy harvesting, expanding its applicability to a broader range of environments and wearables.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"52 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144516256","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}

Therefore, uranium extraction technologies with high efficiency, environmental friendliness, and high selectivity are highly required, but remain challenging. In this work, a microreactor based on cation-exchange reaction (CIEX) is designed for dual-enhanced uranium extraction. The microreactor with local pH regulation, self-generated long-range flow, abundant functional groups, and the photoreduction greatly enhances the transport of uranium toward the adsorbent, as well as the adsorption of binding sites by breaking the adsorption–desorption equilibrium in an energy-saving and environmentally friendly manner. Benefited from the above, a significant uranium removal capacity of 1556 ± 44.5 mg g⁻¹ is reached within 120 min in 30 mg L⁻¹ uranium solution.

The variation of strain has a large and systematic effect on the unit cell volume, and the spin splitting is clearly correlated with the volume, where increased volume favors the HS state. At equilibrium geometry, the local density approximation (LDA) favors the LS state, while the generalized-gradient approximation (GGA) favors the HS state. However, when using the experimental lattice parameters, the GGA also favors the LS. The more accurate HSE and r²SCAN functionals both favor the HS state, but for BTO, on application of a small in-plane compressive uniaxial strain of 2–3%, both the HS and LS states become degenerate in energy thus exhibiting bistable magnetism. Investigation of the magnetic anisotropy (including spin-orbit coupling) shows a change in the (001) to (010) direction of the spin easy axis from the tetragonal to orthorhombic structural phases of Co:PTO/Co:BTO. The application of an external electric field on a Co:PTO slab has a small effect on the magnetic and structural properties of the system.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144516229","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, conventional metamaterial designs typically prioritize optimizing single‐field responses, constraining their adaptability and functional integration potential in complex multi‐physics scenarios where coordinated regulation of multiple fields is required. Here, a V‐shaped 3D electrothermal dual‐function metamaterial (V‐ETDFM) architecture is proposed, enabling efficient and reconfigurable control of both electric and thermal transport. By expanding conduction pathways into 3D space, the proposed V‐shaped structure introduces additional degrees of freedom, enhancing its functional integration and adaptability. Through theoretical and numerical analysis, the feasibility of dynamically controlling cloak parameters, including size, shape, and spatial positioning, is demonstrated by reversibly stretching and compressing the V‐shaped framework based on transformation principles that maintain effective parameter invariance. Experimentally, a series of electrothermal cloaks with varying cloaked regions are fabricated to validate key design principles, confirming the static properties of the theoretical framework, while the implementation of real‐time dynamic tuning presents an avenue for future exploration.

However, conventional fractal antennas are typically fabricated by high‐cost, unscalable, and complicated lithography processes. The inevitable diffraction limit restricts the fabrication of higher‐order fractals and the improvement of multiband infrared response. In this study, a lithography‐free Au fractal nanoantenna platform is developed via film dewetting. The antennas can support multiple resonances over a broad spectral range spanning from near‐infrared to mid‐infrared. The fractal orders can be controlled by adjusting dewetting times. Moreover, due to the spontaneous fractal growth mechanism, the iteration number is theoretically unlimited. Through electromagnetic field simulation and infrared spectroscopy, the fractal order‐dependent multiband resonance mode and dense “hot spots” enabled electric‐field enhancement are revealed. Based on the infrared‐enhanced antenna, a minimum detection limit of 6 nm for the thickness of poly(methyl methacrylate) nanolayers is achieved. Additionally, a noninvasive sensor concept for glucose molecules in aqueous solution is demonstrated. This study presents a lithography‐free approach for constructing high‐generation and large‐area fractal nanoantennas with multiband resonance capabilities, which holds great promise for trace detection and high‐sensitivity biochemical sensing of various analytes in the near‐ to mid‐infrared spectral region.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"630 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144500537","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}

Sustaining a high and homogeneous osmotic pressure within this layer remains challenging, thereby impeding continuous water delivery to the evaporative surface and constraining overall efficiency. In this study, a facile and controllable method to fabricate polyelectrolyte gradient hydrogels via an electric‐field‐driven grafting method is presented. The resulting surface‐localized polyelectrolyte gradient generates an exponentially increasing osmotic pressure, significantly enhancing directional water transport.

The design of nanoparticles is inspired by the tentacles of squid that deformed arbitrarily and exchanged substances with the external environment. A strategy to effectively reduce the energy barrier between liquid–liquid interfaces and amphiphilic lignin nanoparticles (LNPs) with interfacial activities through progressive directed assembly is proposed to achieve stable, reconfigurable encapsulation of liquids. An anisotropic nanoparticle structure consisting of a mixture of hydrophilic and lipophilic sites distributed on a spherical surface is designed to improve adsorption stability at the liquid–liquid interface. The surface polarity and spherical nanoscale dimensions of LNPs are regulated by modulating the phenolic hydroxyl content and molecular weight of lignin. Furthermore, a regulatory pathway between the molecular structure of lignin and the interfacial properties of LNPs is constructed. This strategy yielded more stable equilibrium sites for LNPs interfacial anchoring, resulting in highly integrated and stable structured liquids. This opens a wider range of possibilities for the interfacial design of encapsulation materials, drug delivery channels, and microreactors.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"53 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503662","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, a soft electronic skin (E‐skin) for 3D hand reconstruction, inspired by human biology is proposed, which integrates a multi‐sensor fusion of stretchable carbon nanotubes (CNTs) strain sensors and microelectromechanical system (MEMS) ultrasonic transducers. A straightforward screen‐printing process is introduced‐ to fabricate a multi‐layer stacked structure of the E‐skin.
