Despite significant successes in material design and structure optimization, existing lamellar membranes remain challenging to achieve boosted permeance, selectivity, and stability simultaneously, owing to their limited nanochannel chemistry and unstable nanochannel architecture. Herein, a new class of gel‐locked lamellar membranes (GLLMs) that feature versatile gel‐decorated nanochannel chemistry and gel‐crosslinked lamellar nanochannel architecture are discovered by an original photothermal‐triggered confined gelation (PTCG) approach. In the PTCG, the photothermal‐enabled localized heating from nanosheets is leveraged to trigger rapid and efficient generation of free radicals in their vicinity, allowing for precisely confining polymerization and gelation into lamellar nanochannels. With this method, a series of GLLMs are constructed by easily devising functional monomers and nanosheets and exhibit ultrastable nanochannel architecture with antiswelling ability in many harsh conditions. It is demonstrated that the GLLMs with customized gel‐decorated nanochannels showcase boosted permeance and selectivity over conventional lamellar membranes in many separation scenarios such as isotopic separation, optical resolution, organic solvent nanofiltration, and CO2/CH4 separation. The findings represent a paradigm shift in exploiting a family of advanced lamellar membranes with broader applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"105 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188633","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}

Currently, relaxor ferroelectrics primarily consist of inorganic oxides, while achieving a pronounced relaxation in metal-free molecular ferroelectrics remains challenging due to the strong coupling between the relaxation mechanism and molecular dipole dynamics under applied electric fields. Consequently, this constraint leads to limited studies on their relaxation behavior and hinders progress in high-sensitivity applications, such as photo-pyroelectric detection. Here, Debye-type relaxation is unlocked in the molecular ferroelectric of bis(imidazolium) L-tartrate. In contrast to inorganic counterparts, this metal-free transparent single-crystal ferroelectric exhibits rare Debye-type dielectric relaxation arising from the molecular dipole reorientation that relates to the dynamic motion of organic imidazolium. Exceptionally, broadband photo-pyroelectric effects allow inch-size crystals for wide-spectral photodetection spanning UV to NIR-II wavelengths (266-1950 nm), breaking the conventional bandgap constraint on conventional materials. This work demonstrates that Debye-type relaxor molecular ferroelectrics are promising candidates for high-performance photo-pyroelectric detectors.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"71 1","pages":"e15625"},"PeriodicalIF":29.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194608","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 controlled synthesis of single-crystal neodymium oxychloride (NdOCl) nanosheets with submillimeter sizes (169 µm) and ultrathin thickness (5 nm) is presented using a modified physical vapor deposition (PVD) approach. The NdOCl nanosheets exhibit a high dielectric constant (κ≈11.7), ultralow leakage currents (≈10-7 A cm-2), and a wide bandgap of 4.57 eV. MoS2/NdOCl field-effect transistors (FETs) achieve high on/off current ratios (108), steep subthreshold swings, and suppressed Coulomb scattering, enabling a carrier mobility of 123 cm2 V-1 s-1 at 80 K, a value three times higher than MoS2/SiO2 FETs. The implementation of high-κ NdOCl dielectrics facilitates the successful fabrication of short-channel MoS2 FETs (100 nm) and high-gain logic inverters (60.9).

The continuous balance of interfacial charge attraction and repulsion forces is maintained during the sliding process. By systematically investigating the friction and adhesion force, frictional heating, and electrical outputs of various types of sliding-mode TENGs, this checkered board design TENG (CB-TENG) reduces the sliding friction force and static friction force by more than 30% and 80% compared with the lock-free TENG, and exhibits a maximum temperature reduction of 69.5% as that of the freestanding TENG (FS-TENG). Besides, the CB-TENG achieves 220% enhancement in transferred charge and fourfold enhancement in output energy of FS-TENG over the same sliding distance. Moreover, the segmented electrode design and phase difference in dual-channel AC outputs also enable it function as a direction and displacement sensor for intelligent driving systems.

Nevertheless, there is short of systematic studies on the influences of photocatalytic PCET process by regarding the above two factors at the molecular level. Herein, a series of covalent organic framework (COFs) (Py-Bd COF, Py-Sa COF and Py-OH-Sa COF) were synthesized by co-controlling charge-distribution of skeletons and microenvironment of pores, and were used as photocatalysts for O2-to-H2O2 and H2O-to-H2 reaction. Particularly, the strong electron-withdrawing sulfone groups and strong electron-rich hydroxy groups in Py-OH-Sa COF boosted photo-generated charge separation, also triggered more hydrophilic pores, thus enabling efficient transfer of the photo-induced electrons and protons to catalytic sites. By the above dual regulation, Py-OH-Sa COF showed high photocatalytic H2O2 yield (4.78 mmol g-1 h-1) and H2 production (64.21 mmol g-1 h-1). Moreover, the Py-OH-Sa COF exhibits an extraordinary apparent quantum yield (AQY) of 6.52% and 8.25% at 380 nm for H2O2 and H2 production.

Here, a superhydrophilic/superaerophobic 3D carbonized wood-loaded Ni3Fe-MoO2 (Ni3Fe/MoO2/CW) heterojunction is designed to address these challenges. X-ray absorption fine structure (XAFS) and theoretical calculations reveal that the introduction of MoO2 shortens the Ni─Fe bond length, induces electron transfer from Ni3Fe to MoO2, and regulates the d-band center of Ni/Fe. These optimized Ni─Fe bonds and electronic structure enhance H─OH bond dissociation and H* adsorption/desorption, thereby accelerating the HER Volmer-Heyrovsky step. Simultaneously, for the OER adsorption evolution mechanism on Ni3Fe (1.462 eV), the strengthened Ni─O─Mo bond on Ni3Fe-MoO2 heterojunction reduces the energy barrier (1.092 eV) of the rate-determining step, significantly improving catalytic efficiency. Thus, Ni3Fe/MoO2/CW displays good activity (HER: η-10/-750 = 45/342 mV; OER: η300/1000 = 251/306 mV). Notably, the large specific area of Ni3Fe/MoO2/CW from its nanosheet-particle structure enhances the electrolyte/bubble exchange at the gas-liquid-solid three-phase interface, enabling stable operation at 1000 mA cm-2 for 24 h in an anion exchange membrane electrolyzer.

Here, an effective electrolyte engineering strategy is presented using rare‐earth ions to regulate Zn plating. Combined multiscale experimental analyses and computational modeling reveal that these ions preferentially adsorb onto the prismatic {} facets, suppressing lateral epitaxial growth of the basal (0002) planes. This redirects Zn plating toward an apparent screw dislocation‐driven growth along the [0001] axis. The resulting growth pathway, together with randomly oriented Zn nucleation, yields dense, uniform, and dendrite‐free Zn layers with markedly improved cycling stability and high depth‐of‐discharge operation, thereby challenging the prevailing assumption that dendrite suppression requires (0002)‐oriented growth parallel to the substrate.
