Constructing low-cost evaporators with high hydrophilicity, strong light absorption, good salt resistance, excellent mechanical strength and flexible adaptability is of great significance for solar interfacial evaporation. To this end, a self-floatable double-layer inorganic evaporator (CPDA@HG) was rationally designed using natural halloysite nanotube (HNT). The abundant vertical channels and excellent hydrophilicity of the geopolymer evaporator substrate (HG) endows it with rapid water transfer and outstanding salt dissolution performance, while the carbonized polydopamine modified meta-halloysite (MHNT) as photothermal layer is conducive to enhancing light absorption. Besides, the HNT dispersed in HG can further enhance the hydrophilicity of the evaporator, and the inorganic material characteristics of the geopolymer imparts it remarkable structural stability. As expected, CPDA@HG evaporator demonstrates high evaporation rates of 2.57/4.51 kg m<sup>-2</sup> h<sup>-1</sup> under 1000/2000 W m<sup>-2</sup>, exceeding the currently reported geopolymer-based evaporators. Besides, CPDA@HG exhibits eminent salt resistance and high evaporation rate of 2.36 kg m<sup>-2</sup> h<sup>-1</sup> under a high salt concentration of 10%. Notably, it also displays excellent evaporation performance in dye, acid and alkali wastewater, which can meet the standards of pure water after evaporation. Encouragingly, the evaporation rate is greater than 2.5 kg m<sup>-2</sup> h<sup>-1</sup> in cycling with neglectable fluctuation, indicating the evaporator has distinguished long-term durability. Outdoor tests further substantiates the enormous practical application potential of CPDA@HG. This study provides a versatile and low-cost strategy for development of efficient evaporators for solar seawater desalination and wastewater treatment.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 6","pages":"94908272-94908272"},"PeriodicalIF":0.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147893246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although various biomaterial-based strategies have been explored, coordinating the complex diabetic wound microenvironment remains difficult to achieve. This study proposes a novel multifunctional hydrogel dressing designed to synergistically address multiple issues. Its key innovation lies in dynamically crosslinking deer antler decellularized matrix (dECM) with oxidized dextran via imine bonds, creating a self-healing hydrogel (dECMH). The deer antler dECM, rich in pro-regenerative components, provides a biomimetic scaffold, while Schiff base crosslinking confers mechanical self-healing and injectability. To further address the complexity of diabetic wounds, magnesium gallate metal-organic frameworks (Mg-EGCG) were embedded within the dECMH network, forming Mg-EGCG@dECMH. This innovative combination enables sustained co-delivery of epigallocatechin gallate (EGCG)—possessing antibacterial, anti-inflammatory, and antioxidant properties—alongside magnesium ions that actively promote cell proliferation and vascular regeneration. <em>In vitro</em> analyses confirmed the hydrogel's capacity to enhance endothelial cell proliferation, boost angiogenesis, and mitigate oxidative stress. <em>In vivo</em> evaluations demonstrated accelerated wound healing, manifested by rapid inflammation resolution, ordered collagen deposition, and stimulated neovascularization. Additionally, the material exhibited excellent biocompatibility, hemostatic effects, and antimicrobial activity. This multifunctional dressing synergistically integrates the inherent bioactivity of unique antler decellularized matrix with the multimodal therapeutic effects of metal-organic nanocomposites, offering an innovative and effective strategy for diabetic wound management.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 1","pages":"94908255-94908255"},"PeriodicalIF":0.0,"publicationDate":"2025-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/article_pdf/1989172442296799234.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oxidase-mimetic activity of BM@Metal is independent of ROS and generally enhanced by incorporation of metal nanoclusters.

Here, multilayer borophene nanowalls were successfully synthesized on aluminum foil substrates using chemical vapor deposition. The lattice mismatch between borophene and the Al substrate, reaching 22.56%, results in significant accumulated growth stress that drives the vertical growth of the nanowalls. By carefully tuning the growth conditions, we achieved controlled fabrication of nanowalls with tailored sizes, shapes, thicknesses, and densities.
