The intrinsic reason for the difficulty in recovering functionality at the end of life of conventional polymeric membranes is the permanent chemical crosslinks. Here, we introduce a dynamic homogeneous interpenetrating concept of separation membranes with combined dynamic chemistry and permanent crosslinks. The current membrane design outperforms the conventional membrane with a 3.3-fold increase in flux, being highly competitive with previous reports. The membrane recovers 94.0% of the separation factor with less than a 4.5% fluctuation in flux after physical damage and the healing process. This design advances separation membranes with efficient and recoverable separation performance, establishing a versatile membrane framework for applications including but only limited to water treatment, biofuel production, and resource recovery.&lt;/div&gt;&lt;div&gt;&lt;div&gt;Developing functional polymeric membranes that heal irreversible physical defects while recovering the superior separation performance remains a challenge. Herein, we designed a dynamic homogeneous interpenetrating network of separation membranes, where the polydimethylsiloxane (PDMS)-based dynamic covalent network bridged with imine bonds facilitates self-healing capability, while the PDMS permanent network crosslinked by methacrylate groups ensures efficient separation capability. The healed membrane recovered 92.4% of its mechanical strength and 94.5% of its extensibility, with coarse-grained dynamic simulation, incorporated by the RevCross three-body potential, further observing the molecular-scale bond exchange. Furthermore, the resulting membrane outperformed the conventional membrane with a 3.3-fold increase in flux, also being of significant competitiveness compared with other reports. After healing of the damaged membranes, 94.0% of the phenol separation factor was recovered with a 4.5% fluctuation in flux, which was also consistently verified in other aqueous organic systems. This unique design could establish an engineered membrane platform for reusing waste membranes adaptable to various separation systems.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;Developing functional polymeric membranes that heal irreversible physical defects while recovering the superior separation performance remains a challenge.

Here, we demonstrate that simple acid-base chemistry between readily available metal hydroxides and acidic organic linkers can serve as a general and scalable strategy for constructing diverse MOFs under mild and environmentally benign conditions. This approach bypasses conventional high-energy synthetic routes and enables rapid framework formation with reduced solvent consumption and minimal energy input. Using low-cost gallate-based MOFs as a representative system, we further show that this strategy yields porous materials capable of efficient molecular-sieving separation of challenging alcohol/benzene azeotropes, which are difficult to separate using conventional adsorbents. More generally, this acid-base assembly strategy provides a potentially scalable and environmentally benign platform for MOF synthesis, offering a practical route toward the production of porous coordination materials with reduced synthetic complexity. This may facilitate their broader exploration in gas separation and catalytic applications where processability, cost, and scalability are critical considerations.&lt;/div&gt;&lt;div&gt;&lt;div&gt;Green, scalable, and atom-efficient synthesis remains a central challenge for the practical deployment of metal-organic frameworks (MOFs). Here, we establish a generalized Brønsted acid-base reaction strategy for MOF synthesis, wherein metal hydroxides react directly with organic linkers to yield crystalline frameworks with water as the sole byproduct. This strategy is compatible with various metals (Mg&lt;sup&gt;2+&lt;/sup&gt;/Ni&lt;sup&gt;2+&lt;/sup&gt;/Co&lt;sup&gt;2+&lt;/sup&gt;/Cu&lt;sup&gt;2+&lt;/sup&gt;/Cr&lt;sup&gt;3+&lt;/sup&gt;/Zr&lt;sup&gt;4+&lt;/sup&gt;) and linkers (carboxylates to azolates). Notably, Cr- and Zr-MOFs are constructed from their corresponding metal hydroxides for the first time. The method enables kilogram-scale synthesis of Mg-gallate with an exceptional space-time yield of up to 9,840 kg m&lt;sup&gt;−3&lt;/sup&gt; day&lt;sup&gt;−1&lt;/sup&gt; and a cost of 3.2 USD kg&lt;sup&gt;−1&lt;/sup&gt;, approaching that of commercial zeolites. The gallate MOFs exhibit precise molecular-sieving capabilities for alcohol/benzene azeotropes, with Mg-gallate delivering a methanol productivity of 4.35 mol kg&lt;sup&gt;−1&lt;/sup&gt;, over twice of state-of-the-art MOFs, and an ethanol productivity of 0.74 mol kg&lt;sup&gt;−1&lt;/sup&gt;, representing a 68% impr","PeriodicalId":388,"journal":{"name":"Matter","volume":"9 10","pages":"Article 102918"},"PeriodicalIF":15.7,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148624207","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, the random distribution of atomic-level defects significantly hinders the regulation of internal structures and the improvement of related performances. This work achieves the re-directional distribution of defects by constructing texture channels and inducing a strain mismatch across the thickness. Through phase-field simulations and high-precision microscopic characterizations, the domain configuration, polarization orientation, and total system energy are comprehensively considered to evaluate the local responses. Under the guidance of a field-aligned &lt;001&gt; oxygen vacancy anchoring strategy, an impressive apparent deformation of 3.74% with remarkable temperature stability and fatigue resistance is achieved.

Here, we propose a field-aligned oxygen vacancy anchoring strategy to construct a spatially graded defect architecture with designed asymmetry by leveraging the directional migration along textured channels. Multiscale phase-field simulations and high-precision characterizations collaboratively reveal the significant modulation of domain configuration and surface stress. This induces a steep internal bias gradient, creating a massive trans-thickness strain mismatch. Consequently, a large electrobending deformation of 3.74% featuring a wide operating temperature range (RT-170°C, 3.74%–4.40%) and outstanding fatigue resistance (Δ∼9.1%, after 10&lt;sup&gt;5&lt;/sup&gt; cycles) is obtained.

However, their acoustic performance often degrades under the high-pressure conditions of deep-sea environments. This work addresses a fundamental design challenge: decoupling wave propagation speed from static modulus in engineered materials. Through morphological computation, we have developed an extremal elastic metamaterial that exhibits both high modulus, which resists ambient pressure, and slow wave propagation, enabling low-frequency resonance. By integrating this metamaterial with viscoelastic rubber, we establish a paradigm for underwater sound absorption that exhibits exceptional pressure robustness across a broad range of pressure conditions. Our findings resolve a fundamental conflict between static and dynamic properties in solids, establishing a foundation for the next generation of deep-sea acoustic materials.&lt;/div&gt;&lt;div&gt;&lt;div&gt;The static modulus of natural solids fundamentally scales with the square of elastic wave speed. This intrinsic coupling has long constrained the development of underwater sound-absorbing materials, which demand both high modulus and slow wave propagation for deep-sea applications. This property trade-off causes existing materials to suffer pressure-induced performance degradation. Here, we overcome this fundamental limitation through morphogenesis design, leading to the discovery of an extremal elastic metamaterial. By engineering a tailored distribution of hard and soft modes with weakly coupled isotropic-isochoric eigenmodes, the metamaterial achieves unprecedented decoupling between static modulus and wave speed, delivering a 6.8-fold modulus enhancement relative to the theoretical limit of isotropic materials. Transcending prior designs, a composite integrating this metamaterial with rubber demonstrates pressure-invariant underwater sound absorption, maintaining an average coefficient exceeding 0.9 across a three-octave low-frequency band under extreme pressures up to 4.5 MPa.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;The static modulus of natural solids fundamentally scales with the square of elastic wave speed.
