Nevertheless, despite the advantages of ANE-based thermoelectric technologies, the need for external magnetic fields in most ANE materials hinders their practical applications. The advancement of permanent magnets showing excellent ANE performance is a crucial solution. In this study, we introduce Pt2CoNi-based thermoelectric permanent magnet thin films that demonstrate substantial in-plane and out-of-plane coercivities (exceeding 1 T) and exhibit impressive ANE performance with a thermopower exceeding 1.8 µVK−1. A comprehensive evaluation of the electrical/thermoelectric transport reveals that these films possess a giant transverse thermoelectric conductivity of 4.1 Am−1K−1 at room temperature, which is among the highest values for permanent magnet films. Furthermore, through systematic and high-throughput investigations, we identify a broad range of compositions for Pt2-q-pCo1+qNi1+p films with tunable coercivity and comparable ANE performance, and propose a conceptual design for a single-material-based thermopile utilizing these newly developed materials.

However, the similar physicochemical properties of the CH4 and N2 coupled with the vast structural diversity of MOFs, render the conventional trial-and-error to discovering of high-performance materials particularly difficult. To dresses this challenge, herein, we utilize a data-driven strategy that integrates machine learning (ML) with high-throughput computational screening (HTCS) to facilitate the rational design of novel MOFs for CH4/N2 separation. By mining experimental databases and conducting probabilistic modelling, extracting the ligand fragments and metal centres associated with positive molecular fingerprint features. Finally, fingerprint-positive fragments were assembled into novel ligands and experimentally synthesized with corresponding metals to form a new MOF (Ni-BIC). The synergistic effect of pore size and pore environment enables Ni-BIC to exhibit high CH4/N2 adsorption ratio (6.4) and outstanding CH4/N2 (50/50, v/v) selectivity (13.1) at 298 K and 1 bar.

Nevertheless, conventional light‐driven systems require a direct line‐of‐sight and suffer from limited optical field penetration, restricting their use when considering applications in clinically relevant environments. In this work, we address these limitations by integrating wavelength‐selective liquid crystalline elastomer (LCE) soft actuators with a tailored side‐emitting optical fiber as an endoluminal‐compatible platform. The fiber redistributes the input optical energy to the side output, enabling wavelength‐selective actuation in individual segments of the soft robot body, and providing physical guidance for controlled locomotion along its surface. Beyond the conventional designs that typically integrate LCEs at the waveguide distal tip only for tip steering or gripping tasks, our system comprises a kirigami‐engineered 3D cylindrical architecture fitting around the fiber, and a light‐locking mechanism enabled by photothermal deformation of LCEs. This design permits wavelength‐selective step motion and amplified out‐of‐plane deformation for enhanced locomotive efficiency. We show that programmed temporal illumination patterns result in controllable inchworm‐like locomotion. This line‐of‐sight‐independent locomotion is suited for future applications in confined endoluminal environments.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751478","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 network not only facilitates ordered cation migration through carbon channels, markedly enhancing thermoelectric current and power density, but also effectively traps water molecules to improve environmental stability. Notably, the composite achieves a high thermopower of 26.9 mV K−1 and a peak power density of 0.95 W m−2 under a 20 K temperature difference. And it sustains stable operation for over 46 days without external energy storage. An integrated device built from this material can directly power small electronics such as thermohygrometers, demonstrating its practical potential for low-grade waste-heat recovery.

Spectroscopic analysis and calculations link the design to controlled aggregate packing that suppresses nonradiative decay yet preserves sufficient heat generation.

Herein, we elucidate this mechanism through the molecular design of a conjugated carbonyl compound (DHB) and its oxidized-derivative (o-DHB). While DHB undergoes a 4-electron storage process, strategic oxidation expands this to a reversible 6-electron process in o-DHB. Remarkably, the resultant Zn||o-DHB battery delivers an exceptional specific capacity of 323 mAh g−1 even at a high current density of 5 A g−1 and retains 71% of its capacity after 3,500 cycles, outperforming most reported organic AZIBs. Combined electrochemical and spectroscopic comparative analyses reveal that the high oxidation potential of terminal ortho-hydroxyl groups (C─O─H) in DHB inhibits their full utilization. In contrast, o-DHB enables the reversible reduction of both ortho- and para-C = O groups at relatively low potentials to form C─O─Zn bonds, confirming Zn2+ migration—not H+ insertion—as the dominant charge-storage mechanism. Theoretical calculations further demonstrate that the oxidation engineering lowers the LUMO energy and narrows the HOMO–LUMO gap of o-DHB, promoting electron delocalization, enhancing conductivity, and accelerating reaction kinetics. This work provides profound mechanistic insights and establishes a molecular design principle for developing high-performance organic cathodes for AZIBs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"28 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751476","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}

By exploiting the interplay between bipolar barriers, the device enables modulation of photocurrent polarity—realizing dynamic ternary-state output (‘−1’, ‘0’, ‘+1’) governed solely by laser position, bias voltage, wavelength, and power- coded. The vertical structure exhibits a bipolar response with an ultralow switching bias of −0.025 V (less than 1/10 that of the horizontal structure), along with wavelength-tunable polarity, a responsivity of 0.22 A/W, a detectivity of 8.6 × 109 cm Hz1/2 W−1, and a fast response time of ∼ 121 µs due to its large photosensitive area, shortened carrier transport, and wavelength-dependent optical field distribution.

The non-uniform lithium nucleation and “tip effect” induced uneven potential distribution are the primary causes. Herein, we propose to in situ construct an interlock interface through QSPE (PPAIA) with facial silver (Ag) gauze makeup immediate contacting with LMA. Li-Ag alloy is in situ formed through the immediate contact of Ag in PPAIA with LMA, which decreases the nucleation barrier to uniform lithium nucleation thermodynamically. And the electronic conductive Ag is directly exposed around the Li nuclei to disperse accumulated charges and uniform tip potential distribution, leading to homogeneous Li ions diffusion kinetically. Consequently, homogeneous Li deposition solves the lithium dendrite growth problem. The Li||Li symmetric cell operates stably for 600 h at 0.2 mA cm−2. The LFP||Li battery retains 95% initial capacity after 850 cycles at 1 C, and the NCM811||Li battery maintains 83% capacity retention after 800 cycles at 0.5 C.
