Different from traditional batteries, dual-ion batteries (DIBs) operate via a mechanism in which both cations and anions actively participate in electrochemical reactions at their respective electrodes. This distinctive feature enables DIBs to achieve higher operating voltages, leading to greater energy output. Given that cathode materials play a pivotal role in anion storage, their performance directly determines the overall efficiency of DIBs. However, the limited specific capacity and poor interfacial stability of cathodes remain bottlenecks that hinder the advancement of DIBs. Therefore, a systematic evaluation and comprehensive overview of recent research progress are critically needed. In this review, we analyze the key challenges faced by cathode materials in DIBs and highlight strategies employed to optimize these materials for enhanced anion storage. By consolidating recent research insights, this review aims to guide the development of high-performance DIBs.

与传统电池不同的是，双离子电池（DIBs）是通过阳离子和阴离子在各自的电极上参与电化学反应的机制发挥作用的。这种独特的特性使dib能够实现更高的工作电压，从而产生更大的能量输出。由于阴极材料在阴离子存储中起着关键作用，其性能直接决定了dib的整体效率。然而，阴极有限的比容量和较差的界面稳定性仍然是阻碍dib发展的瓶颈。因此，对最近的研究进展进行系统的评价和全面的综述是必要的。在这篇综述中，我们分析了dib中阴极材料目前面临的挑战，并重点介绍了优化这些材料以增强阴离子存储的策略。通过综合这些见解，本文旨在指导高性能dib的开发。

Biomaterials that can facilitate tissue repair following injury caused by trauma, diseases and aging are highly demanded for the innovation of medicinal and pharmaceutical applications. Self-adaptive biomaterials represent a new class of functional biomaterials designed to interactively regulate the pathological tissue microenvironment post-injury to promote tissue repair in an adaptive manner. This dynamic adaptive interaction involves the biomaterials reacting to the biological cues of tissue microenvironment, which in turn influences the structure and compositions of the biomaterials, creating a feedback loop. In this review, we systematically summarize the components of the inflammatory microenvironment after tissue injury, and underscore its key characteristics and modulation principles, which are instrumental in guiding the design of self-adaptive biomaterials. Subsequently, we outline the current self-adaptive biomaterials, detailing their structures and functionalities. Furthermore, we elaborate the state-of-the-art of their biomedical applications in tissue repair. Additionally, we discuss the challenges and future perspectives of self-adaptive biomaterials in the design of therapeutic strategies and their potential for future clinical applications in tissue repair. It is anticipated that the self-adaptive biomaterials will provide valuable insights and guide the direction of biomaterial development for tissue repair applications.

Hydrogen (H₂) stands as a cornerstone of sustainable energy and an indispensable pathway toward achieving carbon neutrality. Yet, the advancement of the hydrogen economy is significantly impeded by challenges related to storage and transportation. Conventional storage strategies—primarily high-pressure gaseous storage—rely on expensive fiber-reinforced composite tanks that not only escalate costs but also suffer from low efficiency and notable safety concerns. This scenario underscores the critical need for hydrogen storage solutions that are safe, efficient, and economically viable. Carbon-based materials have emerged as a compelling alternative, offering robust hydrogen storage capabilities via both physical adsorption and chemical bonding. These materials promise enhanced safety and improved efficiency for hydrogen transport. This review comprehensively examines the state-of-the-art developments in hydrogen storage across three distinct categories of carbon-based materials: solid carbon materials, gaseous carbon dioxide (CO₂) hydrogen carrier, and liquid organic hydrogen carriers. Moreover, it critically evaluates the reversibility of these storage mechanisms and explores their potential for commercial application, providing insight into their role in the future of the hydrogen economy. This refined exploration aims to guide future research at the intersection of material science and energy technology, fostering innovations that may eventually overcome the current barriers in hydrogen storage and utilization.

氢（H2）是可持续能源的基石，也是实现碳中和不可或缺的途径。然而，氢经济的发展受到与储存和运输相关的挑战的严重阻碍。传统的储存策略——主要是高压气体储存——依赖于昂贵的纤维增强复合材料储罐，这不仅增加了成本，而且效率低，而且存在明显的安全问题。这种情况强调了对安全、高效、经济可行的储氢解决方案的迫切需求。碳基材料已经成为一种引人注目的替代方案，通过物理吸附和化学键结合提供强大的储氢能力。这些材料有望提高氢气运输的安全性和效率。本文全面考察了三种不同类别的碳基材料在储氢方面的最新发展：固体碳材料、气态二氧化碳（CO2）氢载体和液态有机氢载体。此外，它批判性地评估了这些储存机制的可逆性，并探索了它们的商业应用潜力，为它们在未来氢经济中的作用提供了见解。这项精细化的探索旨在指导未来材料科学和能源技术交叉领域的研究，促进创新，最终克服目前氢储存和利用方面的障碍。

The growing demand from flexible and wearable electronic systems for devices that simultaneously offer autonomous energy supply and high-sensitivity pressure sensing has accelerated the development of self-powered pressure sensors. Although substantial research has been conducted on either energy harvesting or pressure sensing mechanisms, most efforts have primarily focused on performance enhancement, lacking a systematic examination of the coupling between energy conversion and pressure response processes. This absence of integration logic hinders the rational design of fully functional devices. This review centers on the critical intersection of ionic materials, self-powered energy conversion, and pressure sensing. It systematically summarizes ion-involved energy harvesting mechanisms such as triboelectric, piezoionic, along with pressure sensing methods that can be coupled with them. Structural design approaches, including porous architectures, gradient structures and so on , are further examined for their roles in enhancing ion transport regulation. Finally, the review outlines current applications in intelligent tactile interfaces, human communication aids, and other related areas. By adopting a unified perspective that connects mechanism, structure, and function, this work proposes a scalable design strategy for self-powered pressure sensors, offering a conceptual framework for future device development and system-level integration.

灵活和可穿戴电子系统对同时提供自主能源供应和高灵敏度压力传感的设备的需求不断增长，加速了自供电压力传感器的发展。尽管已经对能量收集或压力传感机制进行了大量研究，但大多数努力主要集中在性能增强上，缺乏对能量转换和压力响应过程之间耦合的系统检查。这种集成逻辑的缺失阻碍了功能齐全的器件的合理设计。本文综述了离子材料、自供电能量转换和压力传感的关键交叉点。它系统地总结了离子涉及的能量收集机制，如摩擦电，压电离子，以及可以与它们耦合的压力传感方法。结构设计方法，包括多孔结构、梯度结构等，进一步研究了它们在增强离子传输调节中的作用。最后，综述概述了目前在智能触觉界面、人类交流辅助和其他相关领域的应用。通过采用连接机制、结构和功能的统一视角，本研究提出了一种可扩展的自供电压力传感器设计策略，为未来的设备开发和系统级集成提供了概念框架。

Electrocatalytic CO₂ reduction reaction (CO₂RR) represents a highly promising carbon-negative technology, capable of mitigating atmospheric CO₂ concentrations while simultaneously generating value-added chemicals. Rare earth (RE) elements have been extensively used to fabricate advanced electrocatalysts for enhancing the performance of CO₂RR due to their unique 4f electron configurations and redox characteristics. However, critical challenges of achieving precise modulation on CO₂ selectivity with RE elements and their mechanisms are still being pursued. This review systematically summarizes recent advances in RE-based electrocatalysts for selective conversion of CO₂ towards each C₁ (CO, HCOOH/HCOO⁻ and CH₄) or C₂₊ (C₂H₄, C₂H₅OH) products, and aims to construct the relationship between the RE-mediated structure and electrocatalytic performance. Primarily, the fundamental aspects of CO₂RR selectivity and RE characteristics are established. Subsequently, selective modulation mechanisms for specific CO₂RR product and corresponding RE-based catalysts are proposed and classified. We elucidate the synergistic modulation on CO₂ reduction pathway by RE elements unique physicochemical properties (including 4f-electron properties, larger atomic radius, oxygen affinity, and high-valence state) in critical reaction metrics: CO₂ activation, *CO adsorption energy, C–C coupling kinetics, electron/mass transport efficiency and long-term catalytic stability. Building on this foundation, atomic-level control over Cu/RE ratio governs the selective generation of C₁ versus C₂₊ products by modulating reaction pathways, while the intrinsic high-valence stability of RE effectively enhances catalytic durability. Finally, we outline the current challenges and future research directions for RE-mediated CO₂RR systems. This review will offer rational principles and deeper understanding for engineering RE-based electrocatalysts toward desired chemicals under industrial-scale CO₂RR.

电催化二氧化碳还原反应（CO2RR）是一种非常有前途的负碳技术，能够在减少大气二氧化碳浓度的同时产生增值化学品。稀土元素由于其独特的4f电子构型和氧化还原特性，已被广泛用于制造先进的电催化剂，以提高CO2RR的性能。然而，利用稀土元素实现对CO2选择性的精确调制及其机制仍是一个重要的挑战。本文系统地综述了re基电催化剂在CO2选择性转化为C1 （CO， HCOOH/HCOO−和CH4）或C2+ (C2H4, C2H5OH)产物方面的最新进展，旨在构建re介导的结构与电催化性能之间的关系。首先，建立了CO2RR选择性和RE特性的基本方面。随后，提出并分类了特定CO2RR产物的选择性调制机制和相应的re基催化剂。我们阐明了稀土元素独特的物理化学性质（包括4f电子性质、更大的原子半径、氧亲和和高价态）在CO2活化、*CO吸附能、C-C耦合动力学、电子/质量传递效率和长期催化稳定性等关键反应指标上对CO2还原途径的协同调节。在此基础上，原子水平上对Cu/RE比的控制通过调节反应途径来控制C1和C2+产物的选择性生成，而RE固有的高价稳定性有效地提高了催化耐久性。最后，我们概述了re介导的CO2RR系统目前面临的挑战和未来的研究方向。本文综述将为工业规模CO2RR条件下的工程稀土电催化剂催化所需化学物质提供合理的原理和更深入的认识。

The failure of organic coatings protecting metal structures in aerospace and marine engineering under atmospheric corrosion has become a critical threat to structural safety. The NACE report indicates that 38 % of global corrosion costs stem from coating failure. This data is directly associated with the accelerated failure of the coating’s physical barrier caused by Cl⁻ in the marine atmosphere (diffusion coefficient D ≈ 5 × 10⁻¹¹ cm²/s). This review focuses on organic coatings for metal structures and constructs a systematic scenario-mechanism-technology-model framework: ① Analyze three core environmental characteristics—electrochemical catalytic effects of SO₂/NO_x in industrial atmospheres, deliquescence-crystallization cycles of Cl⁻ in marine atmospheres, and synergistic effects of hypoxia, low temperature, and intense UV in aerospace high-altitude environments; ② Reveal multi-scale failure mechanisms: molecular-level degradation (e.g., ester bond hydrolysis in epoxy resins, C-F bond cleavage in fluorocarbon coatings), microscale defect propagation, and macroscopic delamination, establishing a medium penetration-interface reaction-structural deterioration failure clock model; ③ Compare monitoring technologies (EIS has a 12 % false negative rate in marine environments, SKP achieves 89 % accuracy in aerospace interface debonding early warning) and evaluate prediction models (Arrhenius empirical model shows > 20 % error at high temperatures, LSTM-GARCH model achieves < 10 % error under multi-factor conditions). Key bottlenecks identified include: lack of cross-scale modeling for multi-factor synergistic failure, engineering obstacles for self-healing smart coatings, and heavy data dependence of AI models. Future research should focus on quantifying physical-electrochemical coupling mechanisms and integrating fiber optic sensing with digital twins to provide lifecycle protection for high-end equipment coatings.

航空航天和海洋工程中保护金属结构的有机涂层在大气腐蚀作用下的失效已成为威胁结构安全的重要问题。NACE报告指出，全球38%的腐蚀成本源于涂层失效。这一数据与海洋大气中Cl−引起的涂层物理屏障加速失效（扩散系数D≈5 × 10−11 cm2/s）直接相关。本文以金属结构有机涂层为研究重点，构建了系统的场景-机制-技术-模型框架：①分析了工业大气中SO2/NOx的电化学催化效应、海洋大气中Cl−的潮解-结晶循环以及航空航天高空环境中缺氧、低温和强紫外线的协同效应三个核心环境特征；②揭示了多尺度失效机制：分子水平的降解（如环氧树脂中的酯键水解、氟碳涂料中的C-F键解理）、微观尺度的缺陷扩展、宏观层面的分层，建立了介质渗透-界面反应-结构劣化失效时钟模型；③比较监测技术（EIS在海洋环境中假阴性率为12%，SKP在航空航天界面剥离预警中准确率为89%）和评估预测模型（Arrhenius经验模型在高温条件下误差为20%，LSTM-GARCH模型在多因素条件下误差为10%）。确定的主要瓶颈包括：缺乏多因素协同故障的跨尺度建模，自我修复智能涂层的工程障碍，以及人工智能模型对数据的严重依赖。未来的研究应侧重于量化物理-电化学耦合机制，并将光纤传感与数字孪生相结合，为高端设备涂层提供生命周期保护。

While the dynamic characteristic of 4D printing empowers the original static objects fabricated by 3D printing to adapt to more complex application scenarios, their efficacy in orchestrating sophisticated tissue regeneration processes remains controversial given the pathophysiological complexity of native tissues. It is particularly noteworthy that significant changes in properties such as mechanical strength during dynamic transformation pose challenges for its application in load-bearing tissues like bone, warranting further research. Here, 4D printed bone implants were taken as the research objects, beginning with the construction strategies where the advantages of 4D printing over 3D printing in bone tissue engineering were also summarized, leading to the structural design and fabrication techniques of 4D printed bone implants. Then, three major challenges focused on shape transformation, stimulation methods and mechanical strength that 4D printed bone implants faced in practical applications were emphasized in sequence, with corresponding solutions being summarized. Overall, this review systematically analyzed both the advantages and challenges of 4D printed bone implants in the treatment of bone defects, aiming to facilitate the development of intelligent bone implants and accelerate the transition of 4D printed bone implants from basic research to clinical application.

Zinc (Zn) and its alloys have rapidly emerged as biodegradable metals with promising biomedical applications over the past decade. Their unique advantages include tunable degradation rates that align well with tissue healing, diverse biofunctions, and superior mechanical properties. These attributes position Zn alloys as a potential breakthrough for expanding the clinical utility of biodegradable materials and addressing existing technical challenges. This review begins with a historical development of industrial Zn alloys and Zn biology, highlighting the interdisciplinary efforts that gave rise to biodegradable Zn alloys, and the comparison of metallic Zn with other biodegradable metals and Zn-based biomaterials. We then examine the biodegradation process of Zn metals in physiological environments, focusing on material and environmental factors influencing degradation behavior and potential metabolic pathways of Zn degradation products. The biological functions of Zn alloy implants, including osteogenesis, antibacterial activity, angiogenesis, immunomodulation, and anti-restenosis effects, are discussed. Next, critical mechanical properties, such as strength, ductility, stiffness, fatigue, and creep, are also analyzed, along with factors that influence these properties. Furthermore, we explore the performance of Zn alloy implants in cardiovascular, orthopedic, and wound closure applications. Finally, we discuss challenges that must be addressed to facilitate clinical translation of Zn alloys and outline promising future directions including AI assisted design and “smart” Zn biomaterials for precision medicine.
