Conventional coating techniques─such as blade coating, spraying, and spin-coating, the primary methods for existing MXene coatings─require specific substrate properties and face significant challenges in conforming to geometrically complex surfaces. To address these limitations, we developed an electrochemical ion-diffusion-induced gelation approach for fabricating MXene-based composite coatings (Fe2+ M/G). This method enables uniform deposition on substrates of arbitrary geometry while achieving remarkable mechanical strength (198.31 MPa) and infrared stealth capability (infrared emissivity: 0.19). Furthermore, the coating exhibits exceptional electrical conductivity (3571.4 S cm-1), enabling dual functionality: (1) an average electromagnetic shielding effectiveness of 49.35 dB in the X-band and (2) rapid Joule heating (reaching 84 °C at 1.5 V in 120 s), suitable for low-temperature deicing applications. Beyond its core infrared stealth performance, this multifunctional coating system integrates superior physical properties, offering both fundamental insights and practical solutions for developing advanced stealth materials with extended operational capabilities.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"244 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144337480","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}

This study introduces an innovative approach using poly(vinyl alcohol) (PVA)-based ionogels incorporating 1-ethyl-3-methylimidazolium dicyanamide ([EMIM][DCA]) and specific additives: 2-carboxyphenylacetic acid (H), 2-sulfobenzoic acid (S), and 2-carboxyphenyl phosphate (P)). These additives enable successful tailoring of the crystallinity, leading to a substantial increase in the ionic figure-of-merit (zTi), from 0.006 for the PVA ionogel to 0.27 for the ionogel with P additives. Furthermore, the P-additive ionogels exhibit excellent mechanical properties, with a tensile stress of 1.75 MPa and a strain of 460%. A four-pair ionic thermoelectric capacitor made from these ionogels generates 0.33 V and achieves a power output of 2.4 mW m-2.

To address these challenges, gelatin (GEL) was incorporated into the membranes to enhance their osteogenic capacity, while alendronate (ALN)─a bisphosphonate with both osteoclast inhibitory activity and osteogenic potential─was loaded at varying concentrations (1, 5, 10 wt %) to fabricate PG-1ALN, PG-5ALN, and PG-10ALN membranes. The membranes were characterized based on their physicochemical properties, and drug release studies confirmed that the PG-ALN group exhibited sustained ALN release over 28 days. In vitro, PG-1ALN enhanced isolated osteogenesis, but it showed limited efficacy in coculture systems, exhibiting a correlation with unchanged BMP-2 and OSM levels in RAW264.7-conditioned medium. In contrast, PG-5ALN exhibited osteoclast suppression in both isolated and coculture models, supported by the lowest RANKL/OPG ratio of 0.025 (four times lower than that of the PCL group). Micro-CT and histological (H&E, Masson staining) of rat cranial defects demonstrated PG-5ALN's superior bone regeneration; the bone volume fraction (BV) in the PG-5ALN group increased to 5.4 mm3 (control PCL group: 1.3 mm3). The bone mineral density (BMD) in the PG-5ALN group rose to 0.30 g/cm2 (control PCL group: 0.036 g/cm2), marked by dense OCN deposition and minimal TRAP-positive osteoclasts. Notably, PG-5ALN achieved optimal osteoimmunomodulation by balancing osteoblast activation and osteoclast inhibition, thereby advancing the design of dual-functional GBR membranes for osteoclast-active alveolar bone defects.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"25 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144337482","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}

However, practical applications of these materials were constrained by significant swelling and inferior durability in aqueous environments. Herein, natural halloysite nanotubes (HNTs) were intercalated into layered montmorillonite (MMT) membranes to boost the osmotic energy conversion efficiency. The spatial confinement provided by HNTs, along with electrostatic interactions between MMT and functionalized HNTs, mitigates the water swelling of nanofluidic membrane, and the interlayered spacing decreases from 1.60 to 1.26 nm after complete hydration. Furthermore, the hollow structure of HNTs offers short and efficient pathways that improve fluidic permeability and accelerate cation translocation. HNT/MMT achieved a maximum OEC power output of 5.12 W m-2 under a 50-fold salinity gradient of KCl electrolytes, which significantly outperformed the one-component clay two-dimensional (2D) nanofluids.

In this paper, a series of nano core–shell structure La₂Ni_2–<i>x</i>Fe_<i>x</i>O₆@CeO₂ composite catalysts with Ni and Fe double regulation at the B-site were prepared by the sol–gel method and applied to the DRM reaction. The experimental results showed that the addition of the Ni ion at the B position of double perovskite can boost the active sites on the prepared catalyst surface and thereby promote the activation and decomposition of reactants. Simultaneously, the incorporation of Fe ions can also increase the lattice oxygen migration and internal oxygen vacancy concentration of the perovskite, and the La₂Ni_1.6Fe_0.4O₆@CeO₂ sample has the highest surface chemisorbed oxygen content (53.37%). Moreover, the strong interaction between the La₂Ni_2–<i>x</i>Fe_<i>x</i>O₆ core and the CeO₂ shell can enlarge the specific surface area and pore volume, which could further improve the oxygen vacancy concentration and coke resistance ability and thus may stimulate the adsorption and dissociation of CH₄ and CO₂. Meanwhile, the suitable doping ratio of Ni and Fe can effectively enhance the redox performance of the catalyst, and the synergistic effect between Ni and Fe can markedly improve its thermal stability and carbon resistance. The density functional theory was employed to reveal the CH₄ adsorption kinetics, and the calculation results convinced us that the La₂Ni_1.6Fe_0.4O₆@CeO₂ catalyst possessed a lower energy barrier and carbon elimination effect in DRM as expected. Moreover, a fixed-bed tubular reactor was employed to evaluate the catalytic performance of the as-prepared samples, and the 6 h experiment results indicate that the La₂Ni_1.6Fe_0.4O₆@CeO₂ catalyst achieves top reaction performance with the desired H₂/CO of 1, with conversions of CH₄ and CO₂ reaching 93.12% and 89.95%, respectively. Finally, 41 h continuous stability experiments exhibit a slight decrease of CH₄ and CO₂ conversions (average: 89.25% and 84.37%), and the average H₂/CO ratio still remained at 1.01.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"517 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144335088","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}

However, their commercial applications have been hindered due to their weak absorption. Herein, the LiAl5O8 crystal is present as the host for Cr3+ and Ni2+ ions due to its high density of available doping sites (Al3+) per unit volume (0.048/Å3) for Cr3+ sensitizers. By heavily increasing the doping concentration of Cr3+, an unprecedented broad emission band peaking at 773 nm emerges, enhancing the spectral overlap between the emission of Cr3+ and absorption of Ni2+, thus boosting the energy transfer efficiency from Cr3+ to Ni2+. This accelerated energy transfer rate competes favorably against nonradiative processes, allowing higher concentrations of Cr3+ without any photoluminescence quenching. Moreover, by substituting Ga3+ for Al3+, the excitation peak is successfully tuned from 405 to 445 nm, aligning perfectly with commercial blue diode chips. As a result, the optimal LiAlGa4O8: 0.26Cr3+, 0.1Ni2+ phosphor exhibits a broadband emission ranging from 950 to 1600 nm, achieving internal/external photoluminescence quantum yields up to 94.12 and 72.62%, respectively.

Fungal-induced calcium carbonate (CaCO₃) precipitation via urea hydrolysis offers a fast and robust self-healing mechanism to seal the cracks, extending the lifespan while reducing the carbon (C) footprint of concrete infrastructure. However, current studies rely on bulk-scale analytical methods, which lack the spatial resolution and chemical sensitivity to distinguish and map CaCO₃ polymorphs at the nanoscale. This study combined scanning electron microscopy (SEM) and synchrotron-based scanning transmission X-ray microscopy (STXM) with near-edge X-ray absorption fine structure (NEXAFS) spectroscopy to characterize fungal CaCO₃ polymorphs at the nanoscale. CaCO₃ biominerals precipitated by three urease-positive fungi were sectioned into 75–200 nm thin layers. STXM data were collected from at least two spots per section, focusing on Ca (L-edge) and C (K-edge) chemical speciation and elemental quantitative mapping. Calcite, the thermodynamically most stable polymorph, was identified as the predominant mineral phase precipitated by all fungi species, while aragonite and non-CO₃–Ca species (CaCl₂ or Ca adsorbed onto extracellular polymeric substances (EPS)) occurred as minor components. In fungal species 2, we observed nanoscale heterogeneity in Ca phases across five analyzed spots, three dominated by calcite with minor contributions of other Ca species, while the others showed mixed CaCO₃/non-CO₃ phases, as confirmed by NEXAFS spectra. These findings suggest that biomineralization in the fungal micro and nanoenvironment is influenced by localized physicochemical and metabolic conditions that shape mineral phases. C NEXAFS spectra further supported the Ca data, showing C-specific spectral features in the calcite-rich regions across all samples. This underscores STXM’s capability to resolve complexities and mechanisms of fungal CaCO₃ formation (e.g., mineral phase composition, fungal organic-mineral interactions, and spatial heterogeneity). Overall, this study provides critical nanoscale insights into fungal CaCO₃ precipitation, thus providing valuable guidance in optimizing fungal systems in self-healing concrete applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"268 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144335090","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}

However, single functionality and limited integration with wounds hinder their efficacy. Hence, a bilayer micropattern dressing (BMPD) consisting of micropatterned scaffold G5A0.4-MP and an antiadhesion PDMS/A1 layer is prepared. G5A0.4-MP facilitates tissue integration, while the PDMS/A1 layer protects wounds and prevents adhesion. G5A0.4-MP is cross-linked through a photomask, resulting in cylindrical hydrogels with a diameter of 387.4 ± 27.2 μm and a thickness of 417.8 ± 32.3 μm. The swelling ratios of these two layers are significantly different, which allows the detachment of G5A0.4-MP from the PDMS/A1 layer to integrate well with the granulation tissue after lyophilized BMPDs are applied onto wounds. BMPDs with different micropattern interspaces are obtained by changing photomasks, among which the one with an interspace of 100 μm (BMPD-100) shows the best effect on improving wound healing. Hence, a hypoxic ADSC-conditioned medium is loaded into G5A0.4-MP to obtain CM@BMPD-100. CM@BMPD-100 enriches MMP-9 into the micropatterned hydrogel and downregulates the corresponding content in granulation tissue. Additionally, it promotes cell proliferation, regulates the polarization of macrophages from M1 type to M2 type, and enhances vascularization and collagen deposition, and it has been shown to promote diabetic wound healing.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144328911","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}

This review summarizes the various applications of CDs in postharvest processing, including their roles as preservatives, antimicrobial agents, and antioxidants. Specifically, this review particularly focuses on the unique mechanisms of action within chloroplasts and the plant body, examining how CDs affect postharvest plant physiological processes. It also explores the unique antioxidant functions of CDs from a plant metabolism perspective. The fluorescent properties of CDs offer unique advantages in real-time monitoring of quality changes in horticultural products, and they show broad prospects in the development of novel intelligent packaging materials that incorporate smart indicators and nondestructive detection, thereby improving their market competitiveness. As materials in direct contact with edible products, this review also emphasizes the safety and stability of CDs in practical applications.
