In this work, a synergistic design approach is presented to address both challenges by simultaneously modulating the room‐temperature nonergodic relaxor to ergodic relaxor phase boundary and introducing engineered defect dipoles (Pd) in (Bi0.5Na0.5)0.93Ba0.07TiO3 (BNBT) ceramics through B‐site co‐substitution with aliovalent (Sn0.5Sb0.4)4+ complex ions. This dual‐modulation strategy leverages field‐induced phase transitions, the morphotropic phase boundary effect, and the cooperative alignment between spontaneous polarization and defect dipole polarization. As a result, the material system exhibits markedly suppressed negative strain, a substantial internal bias field that facilitates reversible domain switching, and an exceptional electromechanical response. Specifically, an ultrahigh electrostrain of 1.06%, a giant effective piezoelectric coefficient of 1317 pm V−1, and an ultralow strain hysteresis of 7.2% are achieved. These metrics rival those of benchmark lead‐based ceramics such as Pb(Zr1‐xTix)O3.

In this work, a thickness‐driven transition of switching kinetics from the Kolmogorov‐Avrami‐Ishibashi model to nucleation‐limited switching behavior is reported in AlScN films through pulsed transient electrical measurements. In addition, an asymmetry of switching between N‐polar and M‐polar states is observed, which decreases as the film thickness reduces. Integrated differential phase contrast scanning transmission electron microscopy reveals an inhomogeneous distribution of defects between interfacial and bulk regions, as well as the pinning of ferroelectric domains near the interface during switching, which could account for the change of switching behaviors with thickness scaling. The thickness‐dependent switching kinetics and their correlation to defects present an alternative route to engineer the wurtzite ferroelectrics, potentially enabling novel applications in multi‐state ferroelectric memory and neuromorphic computing architecture.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"42 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145002927","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}

In this study, biomass‐derived, amphibious, and erasable adhesives are fabricated by grafting 3‐aminobenzoic acid and 3‐aminobenzeneboronic acid onto epoxidized soybean oil (ESO), yielding ESO‐Am adhesives. These adhesives are dynamically cross‐linked with boroxines, hydrogen bonds, and hydrogen‐bonded hydrophobic nanodomains. ESO‐Am adhesives exhibit strong and durable adhesion to a wide range of substrates under dry conditions, with adhesion strengths comparable to those of commercial counterparts. Remarkably, they also demonstrate exceptional underwater adhesion without the need for post‐curing, achieving an adhesion strength of 5.2 MPa on iron, surpassing previously reported underwater adhesives. This outstanding performance is attributed to the synergistic effect of dynamic boroxine linkages and hydrogen‐bonded hydrophobic nanodomains, which enhance both cohesive strength and interfacial interactions. Importantly, the dynamic cross‐links allow for complete and on‐demand removal of the adhesive by simple ethanol rinsing. In addition, ESO‐Am adhesives are biocompatible, degradable in soil, and reusable, retaining 96% of their original adhesion strength after ten cycles of reuse. The combination of strong amphibious adhesion, full erasability, biodegradability, and reusability makes ESO‐Am adhesives highly promising for a wide range of sustainable and advanced applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"470 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145003074","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}

In contrast, NP NiOx shows weaker hole depletion and a negligible hole barrier and enhances hole extraction, achieving a higher efficiency. The improved interfacial behavior of NP NiOx is attributed to the presence of carbon ligands, which mitigate interfacial recombination.

Among emerging technologies, photothermal membrane distillation (PMD) stands out due to its effective solar-energy conversion, scalability, and simplicity. Here, we report a hybrid PMD membrane fabricated by electrospinning MXene (Ti3C2Tx) nanosheets integrated with silver nanoparticles (AgNPs) onto a poly(vinylidene fluoride-co-hexafluoropropylene) (PH) substrate. The hybrid membrane synergistically combines MXene's exceptional photothermal conversion capabilities and the broad-spectrum antibacterial properties of AgNPs, thereby achieving enhanced permeate flux, excellent salt rejection (>99.99%), and superior resistance to biofouling. Under simulated solar irradiation (1 sun), the fabricated PMD membranes demonstrated permeate fluxes of 0.94 LMH and 3.08 LMH at ambient temperature (∼20 °C) and 30 °C, respectively, achieving a remarkable photothermal efficiency of 63.5% at ambient temperature, with a 35 g/L NaCl feed solution. When challenged with real Red Sea water (39 g/L salinity), the permeate flux showed only a marginal reduction (8.5%), underscoring excellent antifouling performance under realistic conditions. Beyond its desalination performance, the membrane demonstrated excellent antibacterial properties with a 99.8% killing effect. These findings underscore the potential of the Ag@MXene/PHNF membrane as a robust, scalable, and sustainable solution for decentralized water production, capable of producing approximately 24 L of potable water per square meter per day.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"40 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145003240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present a statistical analysis of the crystallographic orientation of MoS2 grown on GBs via chemical vapor deposition, and calculate the energy landscape between MoS2 cluster molecule and underlying MoS2 containing GBs. Our results reveal that the interlayer energy strongly depends on the size, termination edge type and nucleation position of MoS2 cluster. Additionally, the regulatory effect of GBs on MoS2 clusters is notably effective within ∼4 Å but negligible outside. Theoretically, the most favorable stacking configurations at GBs are bilayer MoS2 with 0° and small deflection angles (defined as the angle deviating from the regulation of perfect lattice), consistent with our experimental results.

The aging state MPEA (AG-MPEA) has a multi-scale heterostructure controlled by spinodal decomposition: (I) Bimodal-size structure; (II) Different component regions divided by coherent diffusion phase interfaces; (III) Uniformly distributed Cu-rich and Fe-rich particles in the matrix. The multi-scale heterostructure provides more diffusion phase interfaces and different flow stress regions. The coherent diffusion phase interface hinders the hard transfer of dislocations between different compositional regions, which shortens the free path of dislocation slip. In addition, when crossing from one region to another, dislocations repeatedly face slip congestion, causing the slip band to be filled with accumulated dislocations. Different compositional regions are highly effective in delaying the movement of dislocations, which benefits from their lattice strain and surrounding strain gradient. The enhanced hetero-deformation-induced strain hardening and the formation of microscopic strain bands stabilize plastic deformation and improve ductility. The results indicate that the AG-MPEA exhibited a yield strength of 1,024 MPa and an ultimate tensile strength of 1,293 MPa, along with an excellent ductility of ~28%. Compared to the solid-solution state MPEA (679 MPa, 865 MPa and ~26%), the strength-ductility of the AG-MPEA has been synergistically enhanced.

This study presents a glycosylation‐enabled, chemoselective strategy to label, enrich, and characterize newsECM proteins with augmented specificity and sensitivity. Applying newsECM profiling to bioengineered tumor tissues, either built upon decellularized ECM materials (dECM‐tumor) or as ECM‐free tumoroids, revealed distinct ECM synthesis patterns. Tumor cells cultured within dECM scaffold present elevated ECM remodeling activities, mediated by augmented digestion of pre‐existing ECM coupled with upregulated synthesis of tumor‐associated ECM components. These findings highlight the sensitivity of newsECM profiling to capture remodeling events that are otherwise under‐represented by bulk proteomics and underscore the significance of dECM support for enabling native‐like tumor cell behaviors.
