    Abstract Abstract Hepatectomy, a surgical procedure for liver cancer, is often plagued by high recurrence rates worldwide. The recurrence of liver cancer is primarily attributed to microlesions in the liver, changes in the immune microenvironment, and circulating tumor cells in the bloodstream. To address this issue, a novel intervention method that combines intraoperative hemostasis with mild photothermal therapy is proposed, which has the potential to ablate microlesions and improve the immune microenvironment simultaneously. Specifically, the integrated strategy is realized based on the fibrous chitosan/polydopamine sponge (CPDS), which is constructed from shearing‐flow‐induced oriented hybrid chitosan fibers and subsequent self‐assembly of polydopamine. The CPDS demonstrates high elasticity, excellent water absorption, and photothermal conversion performance. The results confirm the efficient hemostatic properties of the fibrous CPDS in various bleeding models. Notably, in subcutaneous and orthotopic postoperative recurrence and metastasis models of hepatocellular carcinoma, the fibrous CPDS significantly inhibits local tumor recurrence and distant metastasis. Moreover, the combination with lenvatinib can substantially enhance the antitumor effect. This comprehensive treatment strategy offers new insights into hepatectomy of liver cancer, representing a promising approach for clinical management.

    Abstract Solar steam generation is a promising solar energy conversion technology due to its potential applications in water treatment, liquid–liquid phase separation, and sterilization. Therefore, finding highly efficient solar-thermal conversion materials and structures is highly desirable. Here, we developed a membrane consisting of a narrow bandgap semiconductor of CuFeSe₂ nanoparticles (NPs) decorated wood (coded as black wood membrane), for high-efficiency solar steam generation. The CuFeSe₂ NPs display a desirable narrow bandgap of 0.45 eV, and can be used as a novel light absorbing material for highly efficient solar-thermal conversion. Wood served as the substrate for the CuFeSe₂ NPs due to its excellent properties: a mesoporous structure, low density, heat-localization, low thermal conductivity, high hydrophilicity, and cost-effectiveness. All the properties of the designed CuFeSe₂ NP-decorated wood membrane make it an ideal absorber for solar steam generation, allowing it to achieve a high solar thermal efficiency of 86.2% under 5 kW m⁻². Moreover, the CuFeSe₂ NP-decorated wood membrane is cost-efficient and scalable, making it a fantastic material for various applications involving light absorption, photothermal conversion, and water purification.

    Abstract Carbonaceous materials, such as graphite, carbon nanotubes (CNTs), and graphene, are in high demand for a broad range of applications, including batteries, capacitors, and composite materials. Studies on the transformation between different types of carbon, especially from abundant and low-cost carbon to high-end carbon allotropes, have received surging interest. Here, we report that, without a catalyst or an external carbon source, biomass-derived amorphous carbon and defective reduced graphene oxide (RGO) can be quickly transformed into CNTs in highly confined spaces by high temperature Joule heating. Combined with experimental measurements and molecular dynamics simulations, we propose that Joule heating induces a high local temperature at defect sites due to the corresponding high local resistance. The resultant temperature gradient in amorphous carbon or RGO drives the migration of carbon atoms and promotes the growth of CNTs without using a catalyst or external carbon source. Our findings on the growth of CNTs in confined spaces by fast high temperature Joule heating shed light on the controlled transition between different carbon allotropes, which can be extended to the growth of other high aspect ratio nanomaterials.

    Abstract The global fresh water shortage has driven enormous endeavors in seawater desalination and wastewater purification; among these, solar steam generation is effective in extracting fresh water by efficient utilization of naturally abundant solar energy. For solar steam generation, the primary focus is to design new materials that are biodegradable, sustainable, of low cost, and have high solar steam generation efficiency. Here, we designed a bilayer aerogel structure employing naturally abundant cellulose nanofibrils (CNFs) as basic building blocks to achieve sustainability and biodegradability as well as employing a carbon nanotube (CNT) layer for efficient solar utilization with over 97.5% of light absorbance from 300 to 1200 nm wavelength. The ultralow density (0.0096 g/cm³) of the aerogel ensures that minimal material is required, reducing the production cost while at the same time satisfying the water transport and thermal-insulation requirements due to its highly porous structure (99.4% porosity). Owing to its rationally designed structure and thermal-regulation performance, the bilayer CNF–CNT aerogel exhibits a high solar-energy conversion efficiency of 76.3% and 1.11 kg m–² h–¹ at 1 kW m–² (1 Sun) solar irradiation, comparable or even higher than most of the reported solar steam generation devices. Therefore, the all-nanofiber aerogel presents a new route for designing biodegradable, sustainable, and scalable solar steam generation devices with superb performance.
