Herein, this review discusses recent advances in the preparation of multi‐dimensional macroscopic materials from MOFs‐NC and their applications in environmental remediation, including dye adsorption and degradation, pharmaceutical removal, heavy metal ion capture, adsorption and degradation of volatile organic compounds (VOCs), CO2 capture and separation, particulate matter (PM) separation, and others. A summary of two commonly used strategies for preparing MOFs‐NC composites proposes a valuable insight on how processable macroscopic architectures can be effectively achieved. Furthermore, this review provides an overview of the structure‐property‐function relationship between multi‐dimensional MOFs‐NC composites and highlights their versatile applications in the remediation of polluted environments. The mechanisms, challenges, and future prospects of the material in removing environmental pollutants are also present in detail.

This hydrogel can adapt to irregular PF wounds through injectable self‐leveling and achieve transient unilateral adhesion via light‐activated radical crosslinking with tissue‐inherent molecules. In vitro and in vivo studies demonstrate its ability to provide full‐cycle PF management by serving as a long‐lasting physical barrier while offering antimicrobial properties, rapid hemostasis, anti‐inflammatory effects, reversible fibrosis induction, and enhancing pancreatic tissue repair.

Among these, the behavior of excess lead iodide (PbI2) during perovskite synthesis is particularly concerning. Excess PbI2 that promotes perovskite growth will accumulate at grain boundaries during annealing, which restricts the device performance and hinders its long‐term applicability. In this work, an innovative pretreatment strategy is developed by depositing the Cs3ErCl6 quantum dots (QDs) on the perovskite film during annealing, which is different from the traditional post‐treatment strategy by depositing QDs after annealing. It is evident that PbI2 can react with Cs3ErCl6 QDs, enabling its secondary utilization and promoting the secondary growth of perovskite in the vicinity of grain boundaries to inhibit the formation of excess PbI2. The pretreated perovskite layer has a better fit grain, resulting in higher power conversion efficiency (PCE) and better stability of the device. The (FAPbI3) 0.95(MAPbBr3) 0.05 perovskite solar cell treated using the pretreatment method demonstrates a champion PCE of 26.01%. This work offers new perspectives for inhibiting excessive PbI2 growth and thus holds great promise for advancing the commercial viability of perovskite solar cells and contributing to the future landscape of renewable energy.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"47 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603441","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}

Ordering engineering among the nanostructure evolution has emerged as a promising strategy to address these issues, which involves enhancing the structural ordering of SEI, managing the distribution and orientation of inorganic components within SEI, and optimizing the morphostructure and texture of Li deposition. Herein, recent advances in ordering engineering which effectively promote the interface ordering are systematically summarized.

By leveraging rationally designed DNA nanomachines, it is possible to directly attack subcellular structures or deliver therapeutic agents to precise locations, triggering organelle‐mediated cell death. This innovative approach offers several advantages, including enhanced efficacy, lower dosages, minimized off‐target effects, reduced multidrug resistance, and improved therapeutic durability.

Herein, two iron‐chelating and reactive oxygen species (ROS)‐scavenging polymers with thioketal and thioester bonds delivering Lip‐1 are designed and self‐assembled into NPsLip‐1, which pose a triple threat to RGC of Acute Glaucoma via ROS scavenging, iron ion chelation, and potent ferroptosis inhibition. Upon immediate cellular uptake of NPsLip1 by RGCs, the elevated intracellular ROS triggers the cleavage of thioether bonds and the oxidation of thioester bonds, resulting in ROS consumption and simultaneous release of Lip‐1 and exposure of polymer chains with pendant 1,4,7‐triazacyclononane‐1,4,7‐triacetic acid (NOTA) groups. On the one hand, the NOTA groups can chelate with iron ions, thereby inhibiting ferroptosis in RGCs. On the other hand, the released Lip‐1 can inhibit ferroptosis by upregulating glutathione peroxidase 4 (GPX4). Together, NPsLip‐1 with a triple threat markedly reduced ferroptosis and oxidative stress, significantly enhancing the survival of R28 cells. Further, NPsLip‐1 effectively inhibits the RGC ferroptosis and preserves the visual function.

However, the irreversible deposition of K2S2/K2S severely hinders sulfur utilization and cycling stability. Herein, a NiS–DES interfacial regulation strategy is developed that leverages the dual functionality of a deep eutectic solvent (DES) to govern the adsorption and conversion behavior of K2S2/K2S at the catalytic interface, enabling their highly reversible transformation. Specifically, DES forms moderate electronic coupling with NiS to weaken the excessively strong adsorption of K2S and prevent catalyst deactivation. Simultaneously, strong electronic interactions between DES and K2S promote interfacial activation and conversion, thereby extending the reaction pathway and enhancing reduction depth. As a result, the intermediate‐temperature K‐S batteries deliver an initial capacity of 810 mAh g−1 with a minimal capacity decay of 0.02%/cycle over 1300 cycles at 6 mg cm−2 sulfur loading. Even under lean catholyte (4.2 µL mg[sulfur]−1) and higher sulfur loading (12 mg cm−2), they achieve 521 mAh g−1 initially, retaining stability with 0.03%/cycle decay over 500 cycles.
