However, addressing the intrinsic safety concerns of liquid electrolytes and the sluggish reaction kinetics in existing photoelectrochemical storage cathodes (PSCs) remains a significant challenge. In this work, functionalized light-driven composite solid electrolyte (CSE) fillers are systematically screened, and optimized PSC materials are employed to construct advanced photo-assisted solid-state sodium-metal battery (PSSMB). To further enhance the mechanical properties and poly(ethylene oxide) compatibility of the CSE, natural lignocellulose is incorporated, enabling the fabrication of flexible PSSMBs. In situ tests and density functional theory calculations reveal that the light-driven electric field facilitated sodium salt dissociation, reduced interfacial resistance, and improved ionic conductivity (0.1 mS cm-1). Meanwhile, energy-level matching of the PSC maximized the utilization of photogenerated carriers, accelerating reaction kinetics and enhancing interface compatibility between the electrolyte and cathode. The resulting flexible pouch-type PSSMB demonstrates a remarkable discharge capacity of 117 mAh g-1 and outstanding long-term cycling stability, retaining 89.1% of its capacity and achieving an energy storage efficiency of 96.8% after 300 cycles at 1 C.

It discusses methods, challenges, and future directions, alongside the impact of computational modeling and artificial intelligence in accelerating the experimental development of more sustainable surface materials. While significant progress is made in superhydrophobic materials, sustainable superoleophobic surfaces remain a challenge. However, bioinspiration and experimental techniques supported by computational platforms are paving the way to new renewable and biodegradable repellent surfaces that meet environmental standards without sacrificing performance. Nevertheless, despite environmental concerns, and policies, several bioinspired designs still continue to apply fluorination and other environmentally harmful techniques to achieve the required standard of repellency.

However, due to the strong interlayer π–π stacking interactions, the preparation of high‐quality and atomic‐scale single‐crystalline conjugated MOF structures continues to pose a significant challenge. The investigation of its nonlinear optical (NLO) property and application for ultrafast photonics is still rare. Herein, the ultrathin Cu3(HHTP)2 and Ni3(HHTP)2 (HHTP = 2,3,6,7,10,11‐hexahydroxytriphenylene) nanosheets (CuHHTPNs and NiHHTPNs) with single‐crystalline characteristic are prepared by surfactant‐assisted solution synthesis strategy. Moreover, the π–π stacked CuHHTPNs(NiHHTPNs)/graphene van der Waals heterostructures (CuNsG‐VHS and NiNsG‐VHS) are achieved by ultrasound‐assisted method. According to characterization analyses and theoretical simulations, this preferable stacking ultrathin van der Waals heterostructures exhibits superior π‐conjugated electron cloud extension, charge transfer, and NLO properties. Noticeably, the third‐order NLO polarizability of CuNsG‐VHS keeps in a relatively high level compared with the reported 2D saturable absorber materials in the near‐infrared wavelength range. Based on these outstanding properties, CuNsG‐VHS can serve as an excellent saturable absorber to achieve fundamental mode‐locking with femtosecond pulse duration, and high‐order harmonic mode‐locking with GHz repetition frequency. These demonstrations provide a valuable strategy for the development of promising conjugated MOFs for ultrafast photonics and advanced optoelectronic devices.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"8 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143435435","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}

This study introduces an autonomous, moisture‐driven flexible electrogenerative dressing (AMFED) that overcomes these limitations. The AMFED integrates a moist‐electric generator (MEG), an antibacterial hydrogel dressing, and concentric molybdenum (Mo) electrodes to provide a self‐sustaining electrical supply and potent antibacterial activity against Staphylococcus aureus and Escherichia coli. The MEG harnesses chemical energy from moisture to produce a stable direct current of 0.61 V without external input, delivering this therapeutic electrical stimulation to the wound site through the Mo electrodes. The AMFED facilitates macrophage polarization toward reparative M2 phenotype and regulates inflammatory cytokines. Moreover, in vivo studies suggest that the AMFED group significantly enhances chronic wound healing, with an approximate 41% acceleration compared to the control group. Using a diabetic mouse wound model, the AMFED demonstrates its effectiveness in promoting nerve regulation, epithelial migration, and vasculogenesis. These findings present a novel and efficient platform for accelerating chronic wound healing.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"29 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143435446","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 skin mucus of Andrias davidianus plays a critical role in self-protection and tissue repair, yet the fundamental regenerative factors and mechanisms involved remain elusive. Here, this work presents evidence that glycosaminoglycans (GAGs) derived from the skin secretion of Andrias davidianus (SAGs) serve as potent mediators of angiogenesis and inflammatory remodeling, facilitating efficient healing of diabetic wounds. Mechanistic studies reveal that SAGs promote macrophage polarization toward an anti-inflammatory and pro-regenerative phenotype (CD206+/Arg1+) via glucolipid metabolic reprogramming. This process suppresses excessive inflammation and enhances the expression of VEGF and IL-10 to create a facilitative microenvironment for tissue regeneration. Additionally, this work develops SAGs-GelMA composite microspheres that address multiple stages of wound healing, including rapid hemostasis, exudate control, and activation of endogenous regenerative processes. This engineered approach significantly improves the scarless healing of diabetic wounds by facilitating the recruitment and activation of reparative macrophages. The findings offer new insights into the regenerative mechanisms of Andrias davidianus and highlight the potential therapeutic application of SAGs in tissue repair.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2417801"},"PeriodicalIF":27.4,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447490","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}

Unlike traditional processes that rely on toxic solvents such as N-methyl-2-pyrrolidone (NMP), the DBE technique uses solvent-free methods, reducing environmental impact and production costs while enhancing compatibility and performance. However, polytetrafluoroethylene (PTFE), the only binder currently used for large-scale DBE fabrication (binder fibrillation), faces potential regulatory restrictions under Polyfluoroalkyl Substances (PFAS) guidelines and limits Li-ion conductivity, elastomeric properties, and particle adhesion. This study explores a novel dual-binder system, termed the \"bollard hitch\" model, designed to overcome these limitations as the first PTFE-less binder for binder fibrillation. Poly(acrylic acid)-grafted sodium carboxymethyl cellulose (PC) acts as the \"bollard,\" strongly attaching to the PTFE \"anchor.\" This binder system reduces PTFE usage by over 70% and enables the fabrication of high-mass loading cathodes (up to 90 mg cm- 2, 15.6 mAh cm- 2) with superior performance.

The ternary heterojunction made of C5‐16:L8‐BO binary acceptors diluted with D18 shows the strongest structural order, benefiting from the strong interactions between L8‐BO and C5‐16. The enhanced structural order within the photoactive layer prepared by layer‐by‐layer deposition of the diluted p‐type and n‐type heterojunctions contributes to enhanced light absorption, improved charge transport, and inhibited charge recombination.

However, the challenges associated with the synthesis of ultrathin Carpy‐Galy films and understanding the impact of strain on their properties limit their integration into devices.

Using density‐functional theory calculations, scanning probe microscopy, X‐ray diffraction, scanning transmission electron microscopy, and polarization switching experiments, it is confirmed that these films possess exceptional ferroelectric properties, including a polarization of 18 µCcm−2 – more than three times higher than previously reported – as well as persistence of ferroelectricity down to a single‐unit‐cell thickness.

Moreover, these 1D inorganic electrides exhibit lower work functions (≈3 eV) on the (001) surface, significantly enhancing their applications in ammonia synthesis. Further experimental synthesis and characterization suggested that 1D inorganic electrides exhibit extremely high stability owing to the strong hybridization between IAEs and atoms and the small surface area of IAEs.
