Herein, an effective and facile interfacial reaction strategy is developed to fabricate 3D COF 320 membranes with variable pore sizes. By simply changing composition of dual acids, both the framework structure and the membrane assembly process are regulated, enabling effective control over pore sizes and membrane thicknesses. The membranes exhibited high solvent permeance and could efficiently separate molecules with similar molecular weights. Moreover, further investigations revealed that the as‐prepared membranes are solvent‐responsive, enlarging their intrinsic pore sizes when exposed to methanol. By varying the ratio of water to methanol, the membrane could facilitate the graded molecular sieving of complex dye mixtures, achieving solute‐solute separation.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143805620","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, poor cycling performances and low-temperature electrochemical properties remain major technical issues in MIBs. Electrode materials impose a great influence on the electrochemical characteristics of MIBs. 2D transition metal dichalcogenides (TMDs) are potentially excellent electrode materials for MIBs on account of their open framework and outstanding electrochemical characteristics. In this work, the pre-intercalation modification strategy is adopted to design the K+ pre-intercalated WS2 material as the electrode material of MIBs. Structural characterizations and density functional theory (DFT) calculations demonstrate that the Mg2+ diffusion barrier in the K+ pre-intercalated WS2 is effectively lowered accompanied by the interlayer expansion in the layered structure, aiding quick ion diffusion and reliable Mg2+ ion storage. Consequently, the K-WS2 electrode demonstrates excellent electrochemical performances, a reversible capacity of 217 mA h g−1 at 0.2 A g−1 with outstanding cycling stability. In addition, the K-WS2 electrode is capable of running smoothly at low temperatures, showing superior capacity preservation of 97% upon completion of 1000 cycles at −30 °C. This work supplies an uplifting means to the modification and optimization of cutting-edge electrode materials for MIBs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"13 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143806064","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}

Despite notable progress, the unavoidable high thermal budget in conventional silicon-transistor-based 3D integration results in high process complexity and degraded device performances. Herein, a heterogeneous 3D complementary metal-oxide-semiconductor field effect transistor (CMOS FET) technology, integrating carbon nanotube (CNT) transistors into Si back-end-of-line (BEOL) processes is presented. Experiments show that CNT transistors can be integrated using a low-thermal-budget (<150 °C) process, requesting little modification in the well-established Si processes. Comparative analysis also indicates that the low-thermal-budget integration results in little damage to the Si components. More importantly, Si-BEOL-compatible gate control enhancement and threshold voltage modulation techniques for CNT transistors are developed, resulting in noise margin improvement and power suppression in inverters. The experimental results further demonstrate that CMOS FET inverters feature high noise margins (NMH/NML = 0.404/0.353 × VDD) and ultra-low power consumption (390 pW, >100× lower than those in the Si counterparts). Moreover, numerical simulations predict that 14-nm-node CNT/FinFET 3D CMOS FET inverters outperform the conventional FinFET counterparts in noise margins and power efficiency. These findings demonstrate the possibility of 3D integration's complexity reduction by adopting <150 °C CNT-based processes.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"287 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143806068","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}

The efficient separation of the layers within solar cells is crucial for successful recycling. However, current methods for interlayer dissociation, which rely on pyrolysis and organic reagent dissolution, are slow, produce toxic byproducts, and hinder complete component recovery. This study introduces an innovative instantaneous pressure-difference strategy for separating photovoltaic modules. During the rapid pressure release process, water vapor generates a significant pressure differential, causing the separation of module interlayers owing to the abrupt expansion of water vapor. The proposed method enables the complete separation of all components in waste CIGS cells within 150 s. The method effectively enriches valuable metals and facilitates their leaching recovery., while the separated ethylene-vinyl acetate and polyethylene terephthalate exhibit properties comparable to those of commercial materials. Life cycle assessment indicates that the proposed recycling strategy has a lower environmental footprint and cost compared with conventional methods. Additionally, this approach can be applied to the delamination and recycling of other retired photovoltaic modules. Overall, the strategy provides a viable solution for managing end-of-life solar panels, contributing to the development of a circular economy.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"91 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143806416","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, CEAs are limited by fragility, shrinkage, lack of a dermal layer, and risks of contamination. Here, aiming to overcome these limitations, this work develops a personalized skin equivalent featuring an engineered scaffold composed of electrospun poly(ε-caprolactone) (PCL) functionalized with the bioactive peptide fluorenylmethyloxycarbonyl-phenylalanine-arginine-glycine-aspartic acid (Fmoc-FRGD). This scaffold is designed to mimic the natural extracellular matrix (ECM), promoting cellular adhesion, integration, and proliferation while maintaining structural integrity. In vitro analysis demonstrated the scaffold's ability to support multi-layered human skin cell growth, while in vivo experiments confirmed its efficacy in facilitating wound closure and full-thickness skin regeneration in a murine model.

By constructing an HZO-ZrO2 ferroelectric superlattice to achieve fast switching and a low depolarization field, both the duration and intensity of charge injection are reduced during polarization switching. Thus, the charge injection effect during polarization switching is effectively suppressed, resulting in the enhanced endurance of over 1012 cycles.

The rational regulation of active hydrogen (*H) is pivotal for NO2−-to-NH3 conversion, yet it remains a significant challenge in the context of NO2RR. In this study, molybdenum boride (MBene) multilayers are introduced as an electronic support to integrate with palladium (Pd) nanoparticles, creating dual catalytic sites that effectively balance the adsorption of *H and *NO2−, thereby enabling synergistic catalysis of the NO2RR. Theoretical and experimental analyses revealed that *H is efficiently generated on Pd sites and subsequently undergoes spillover to *NO2−-adsorbed MBene surfaces, facilitating accelerated hydrogenation and NH3 synthesis. Consequently, the Pd/MBene catalyst demonstrated exceptional performance, achieving a high NH3 Faradaic efficiency of 89%, an NH3 yield rate of 16.9 mg h−1 mgcat−1, and remarkable cycling stability at a low applied potential of -0.3 V versus RHE. Motivated by the outstanding NO2RR performance, the Pd/MBene catalyst is further utilized as the cathode catalyst to construct Zn-nitrite and formaldehyde-nitrite batteries. These systems demonstrated the dual functionality of simultaneous NH3 production and electricity generation, highlighting the potential of Pd/MBene as a versatile and efficient catalyst for sustainable energy conversion.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143798547","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}
