Macroscopic labels are straightforward to fabricate and read but are vulnerable to duplication, whereas microscopic physically unclonable functions (PUFs) offer high security at the expense of fabrication complexity and verification cost. Here, we propose a wrinkle-assisted fluorescent hierarchical PUF strategy that integrates controllable replication with nanoscale randomness through transfer printing of self-assembled quantum dot (QD) nano-meshes via a surface-engineered PDMS wrinkled stamp. Random wrinkles with rigid and hydrophilic surface shells are initially generated on PDMS via UVO-induced bilayer buckling and subsequently subjected to post-wrinkle surface engineering to restore a soft and low-surface-energy stamp, which is essential for high-quality and durable hierarchical PUF patterns. The reproducibly transferred micro-fingerprint patterns can be conveniently recorded using portable imaging devices for rapid verification; QD-assembled nano-meshes within the wrinkle ridges maintain intrinsically stochastic features arising from interfacial self-assembly and wrinkle-assisted transfer, and cannot be deterministically reproduced. When combined with deep learning and feature-based comparison, this architecture supports accurate and real-time identification with incremental scalability. This work offers a promising PUF architecture to combine scalable replication and intrinsic security in the anti-counterfeiting field.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"13 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751480","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 layer‐by‐layer integration for multimodal sensing often results in bulky devices and is prone to interfacial delamination. Inspired by the hierarchical information processing of human tactile system, we present an embodied multimodal sensing textile (EMST) enabled by a multiscale textile‐structure design, from composite functional yarns to engineered woven architectures. The EMST achieves integration, decoupling, and tactile mapping of position and pressure signals directly at the textile‐structure level by leveraging on‐body current‐division and resistance‐gradient principles. A geometric model of the touch trajectory is established to elucidate the decoupling mechanism for 2D coordinate sensing. The controllability of the EMST in virtual car motion, as validated by MuJoCo simulations, further demonstrates its potential for assistive interaction with intelligent navigation systems. This work provides a practical and scalable technical strategy for advancing conformable tactile textile interfaces and next‐generation human‐machine interaction.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"19 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147739220","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}

Based on how light and heat contribute to the reaction dynamics, the mechanisms of photothermal cooperative catalysis can be classified into three distinct types, including thermo‐assisted photocatalysis, photo‐assisted thermocatalysis, and synergistic photothermocatalysis. This review starts with the introduction of different principles and reaction forms for each reaction type. Then we introduce different catalysts, reactions, and reactors in photothermal catalysis.

Their operational reliability necessitates regular lubricant inspection to prevent premature failure, posing a challenge to the development of high‐accuracy and low‐cost online monitoring sensors for oil. This study developed a smart triboelectric metal‐polymer sliding bearing (T‐MPSB) based on diamond‐like carbon (DLC) coating for the real‐time monitoring of the lubricating oil. Fluorine and nitrogen codoped diamond‐like carbon (FN‐DLC) coatings were systematically investigated as promising electronegative materials with enhanced triboelectric output and extraordinary tribological robustness. Integration of the FN‐DLC coating to the sliding bearing system reduced the friction under boundary lubrication and enabled self‐sensing ability for intelligent monitoring of moisture, wear debris, and oxidation in the base lubricating oil. Additionally, commercial engine oil with full additive packages was used to demonstrate the ability of the T‐MPSB in monitoring the consumption of additives, which has never been reported before. Furthermore, an intelligent monitoring system for the consumption of lubricant additives was realized by combining the T‐MPSB with AIoT technology, thereby achieving online visualization of the oil condition and early warning of additive depletion. This study provides a feasible pathway for the intelligent monitoring of lubricant conditions toward future smart machinery.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"3 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147739218","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}

Throughout its twelve-year funding period, the centre has been guided by the vision of its main funders—the Swiss National Science Foundation and the University of Fribourg—to draw inspiration from biological systems to create stimuli-responsive materials, understand how these materials interact with living systems, and translate the this knowledge into real-world applications, in the fields of chemistry, physics, materials science, and biomedicine.&lt;/p&gt;\u0000&lt;p&gt;The Centre is headquartered at the Adolphe Merkle Institute of the University of Fribourg (UniFr), with the École Polytechnique Fédérale de Lausanne (EPFL) and the Eidgenössische Technische Hochschule Zürich (ETHZ) as its primary partner institutions. Since its inception, a total of 30 research groups from six Swiss institutions and six other universities in the UK, Germany, Austria, Belgium, Finland, and the USA have participated in this venture. These groups work at the intersection of several disciplines, including chemistry, physics, biology, materials science, and medicine. The NCCR was initially launched under the directorship of UniFr professors Christoph Weder and Curzio Rüegg. In 2021, the directorship transitioned to UniFr professor Ullrich Steiner and EPFL professor Esther Amstad, who have since led the centre through the second half of its funding period.&lt;/p&gt;\u0000&lt;p&gt;The Centre's research programme has traditionally been organised into three modules: mechanically responsive materials, photonic materials, and bio-interfaces. These three areas of research have shaped the NCCR's identity and informed its activities throughout its twelve-year funding period. At the same time, the NCCR has launched several other complementary research programmes. For instance, in 2018, an interdisciplinary programme combining microfluidics, sensing technologies, and cell biology was initiated to create a dynamic lab-on-a-chip platform for investigating cell–material interactions. Other examples include cross-disciplinary collaborative projects investigating long-standing challenges in cancer diagnosis, optical manipulation, and bio-inspired power conversion. In 2022, a new module was launched to support projects with translation potential. These projects focus on edible, bio-inspired colours, healable polymers, soft actuators, and carbon capture materials. The NCCR also offers Women in Science Fellowships, which have funded eleven projects led independently by female researchers. This programme has significantly advanced the careers of the fellows, with six of them transitioning to assistant professorships and equivalent positions worldwide.&lt;/p&gt;\u0000&lt;p&gt;Since its launch, the NCCR has made significant contributions to its areas of activity.

However, the fundamental conflict between the high electromagnetic loss required for radar stealth and the low emissivity essential for infrared stealth has long impeded progress toward such intelligent and compatible systems. Herein, we break this limitation through superelastic magnetic nanofiber aerogels (MNFAs) featuring a semi-honeycomb cellular architecture. Such a design enables on-demand, synchronous switching between “on” and “off” states for dual-band stealth, while maintaining outstanding mechanical robustness, as evidenced by stable performance over 500 compression cycles at 50% strain. In the released state, the MNFAs exhibit exceptional radar wave absorption (reflection loss of –42 dB) and outstanding thermal insulation (the thermal conductivity of 51 mW m⁻¹ K⁻¹), providing simultaneous stealth against both spectra. Upon 70% compressive strain, the effective absorption bandwidth vanishes while the surface temperature rises dramatically, simultaneously disabling both the radar and infrared stealth functions. This study elucidates the mechanism of mechanically driven multispectral synergistic intelligent regulation through multi-scale analysis, providing a new paradigm for the design of next-generation adaptive camouflage materials.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"30 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147736026","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}

Herein, we investigate the synergistic effects of structural and solvation regulation on dihydroxyanthraquinone (DHAQ)-mediated “dead zinc” revitalization kinetics for ZFBs. 1,5-DHAQ, featuring two alfa-position hydroxyl groups, results in a more compact solvation shell and higher zinc affinity to facilitate the diffusion, desolvation, and absorption processes.

However, the conventional monolithic gel constituted with randomly oriented polymeric walls significantly increases the diffusion/transfer resistance of water and contained matters. Here, we demonstrate a gel-granule ensemble evaporator, featuring programmatically assembled structures and functionalities, for enhanced solar evaporation and synergistic applications. Unlike the nano-microchannels inherent in monolithic gels, the microfluidic-directed ensemble of photothermal gel-granules, assembled through self-healing forces, creates unique interconnected gaps that facilitate efficient light absorption, thermal management, and mass transfer, leading to a higher content of intermediate water and a reduced evaporation enthalpy. A 3D ensemble evaporator attains an evaporation rate of 3.2 kg m⁻² h⁻¹ under 1 sun, and demonstrates exceptional salt resistance thanks to powerful capillary action and compensatory flows driven by the Marangoni effect. By substituting photothermal components with functional materials, photocatalysis, fluorescence, and structural colors are readily customized, expanding the in situ practical application of solar evaporators.

However, the correlations between ion–polymer interactions and ion-doping retention characteristics remain poorly understood. Notably, strategies that simultaneously control ion–polymer interactions and synaptic retention via electrolyte ions as independent design variables remain underexplored. In this study, we demonstrate that hydrogen-bond-mediated anion–polymer interactions play a central role in governing synaptic retention. Anions with asymmetric charge distribution give rise to strengthened hydrogen-bond interactions, which regulate ion dynamics and suppress ion back-diffusion. This hydrogen-bond interaction effectively transforms ion relaxation behavior from a diffusion-dominated to an interaction-stabilized regime within the organic semiconductor. As a result, the devices exhibit enhanced synaptic retention together with excellent linearity during long-term potentiation/depression (LTP/D). These findings provide molecular insight into hydrogen-bond-mediated synaptic retention in EGSTs, offering a mechanistic basis for the rational optimization of ion-driven neuromorphic devices.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"2 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147736163","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}
