Graphene and related materials are emerging revolutionary materials due to fascinating stimuli-responsive physiochemical properties having widespread applications in developing advanced nano-systems for detection, diagnostics, and therapeutics in biomedical fields. Various materials like metal nanoparticles, polymers, dyes, drugs, and proteins could be combined yielding graphene-based composite materials (GBCMs) to synergistically fulfill different biomedical requirements. The 2D conjugated structure, easy surface functionalization via covalent or van der Waal interactions, and combination with different components for versatile functionalities altogether contribute to the development of GBCM for healthcare applications. This review specifically focuses on GBCMs and discusses specific material properties relevant to their material applications in healthcare. Furthermore, the synthesis, toxicity, and biocompatibility of these GBCMs, and their interactions with biological materials are thoroughly discussed. Importantly, the recent cutting-edge applications in the field of healthcare, including its role in the development of antibacterial, anti-viral, and photothermal therapies, wound healing, drug delivery, neurodegenerative disease therapy, and biosensing based on GBCMs are well-updated. Additionally, the applications of GBCMs in point-of-care devices, wearable electronics, and tissue engineering are well summarized. We hope this review opens up more possibilities to design more innovative healthcare materials derived from graphene. © 2025 The Authors

Lithium dendrite formation poses a significant safety hazard in lithium-ion batteries（LIBs）, severely impeding their widespread adoption and further technological advancements. Here, we present a novel quaternized polybenzimidazolium（q-PBI） to armor polyimide（PI） nanofiber separator（q-PBI@PI）, in which the q-PBI containing lithiophilicity and anionphilicity sites serves as the multifunctional nano-layers to suppress the Li dendrite and reinforce the mechanical properties of PI nanofiber ***, the q-PBI@PI separator displays an unprecedented mechanical strength of 82.8 MPa, significantly outperforming previously reported PI nanofiber membranes（typically below 50.0 MPa）. Besides, we demonstrate that the q-PBI@PI separator simultaneously possesses low nucleation overpotential（59 mV） and exceptional average coulombic efficiency due to the suppression of Li dendrite. Importantly, q-PBI@PI-based Li||Li battery enables a stable Li plating-stripping at 1.0 m A cm-2for600 h. Attributing to these exceptional merits, the armored PI separator-based LIBs display remarkable specific capability and capacity retention. The density function theory calculations reveal that q-PBI is conducive to the desolvation of Li+and can immobilize Li+and PF6-ions near affinity sites of PI nanofibers for inhibiting the formation of Li dendrites. Our work paves a new avenue for the design of next-generation high-performing separators in LIBs.

Journal of Industrial and Engineering Chemistry 2025年 148卷 92-108页

作者： Deng, Yi Chai, Guoliang Zhang, Yinghe Carbon Materials Research and Comprehensive Application Shenzhen Key Laboratory of Advanced Functional Carbon Materials Research and Comprehensive Application School of Science Harbin Institute of Technology Shenzhen Shenzhen518055 China State Key Laboratory of Structural Chemistry Fujian Institute of Research on the Structure of Matter Chinese Academy of Sciences Fujian Fuzhou350002 China

Extensive lithium reserves in aqueous environments such as salt-lake brines, subterranean brines, and seawater underscore the importance of brine extraction in current research. Addressing the lack of a systematic framework for categorizing brine extraction technologies, this review presents a classification based on phase interactions within brines, specifically liquid–liquid and liquid–solid interfaces. The liquid–liquid system includes precipitation methods using carbonates, aluminates, and phosphates, along with extraction techniques involving β-diketones, crown ethers, organophosphorus compounds, and ionic liquids. The liquid–solid system focuses on lithium-ion transport and material interactions, encompassing transmembrane transport mechanisms (e.g., nanofiltration, liquid membranes, electrodialysis), adsorption embedding (with aluminum, manganese, and titanium-based adsorbents, and electrochemical ion deintercalation), and adsorption adherence (featuring natural ores, ion-exchange resins, and carbon-based materials). The review outlines the core principles of these methods and highlights cutting-edge technologies in brine lithium extraction. By integrating various techniques, these advancements aim to enhance efficiency, cost-effectiveness, and environmental sustainability, significantly improving the feasibility of lithium extraction from brines and supporting the sustainable development of the global lithium supply chain. © 2025 The Korean Society of Industrial and Engineering Chemistry

With the advancement of hypersonic vehicles, extreme high temperature environments have imposed increasingly stringent requirements on the performance of thermal protection systems. Consequently, the development of high-performance thermal protection materials capable of withstanding extreme conditions has become a primary focus of current research. Ultra-high temperature ceramics (UHTCs) and their composites, known for their excellent oxidation resistance and ablation performance, are regarded as highly promising non-ablative thermal protection materials. This paper provides a systematic review of recent research progress on UHTC composites in several key areas, including innovations and optimizations in fabrication processes, exploration of toughening strategies and mechanisms, in-depth studies on oxidation and ablation resistance mechanisms, and the development and potential applications of high-entropy ceramics. Furthermore, the paper discusses the practical application prospects of UHTCs and their composites in extreme environments, analyzes the current technical challenges, and proposes future research directions and priorities.
