Zinc-ion batteries (ZIBs) have gained significant attention as promising candidates for large-scale energy storage systems owing to their low cost, environmental friendliness, and inherent safety, and have become a key focus of both academic research and industrial development strategies. However, significant challenges must be resolved, such as suboptimal charge kinetics, inadequate electrode structural stability, and complicated and costly manufacturing methods, prior to achieving meaningful advancements. Building on this foundation, this review offers a comprehensive overview of electrode materials, beginning with the fundamental factors that influence their electrochemical performance, such as electronic conductivity, ion diffusion pathways, structural stability, redox activity, and surface/interface characteristics. A clear understanding of these parameters is essential for guiding the rational design and optimization of high-performance electrodes for ZIBs. Secondly, we critically assess the current progress, identify persistent limitations, and explore potential strategies to overcome the challenges in achieving long-term cycling stability and fast reaction kinetics. Detailed analyses of structural engineering approaches, electrochemical behavior, and zinc-ion storage mechanisms across diverse material systems are presented to provide deep insights into the design principles driving next-generation AZB development. Finally, we also included a comprehensive outlook on the future development of ZIBs by identifying critical challenges and promising opportunities to drive their rapid progress and extensive practical deployment in the field.

Polymers, as foundational materials in modern industry, face persistent challenges in precision design and performance improvement due to structural intricacy, multifunctionality requirements, and sustainability imperatives. Machine learning (ML) has emerged as a transformative tool for elucidating structure–property correlations and expediting polymer material discovery. This review systematically examines ML applications across three domains: autonomous synthesis via reaction kinetic modeling, cross-scale property prediction linking polymeric configurations to bulk behavior, and sustainability-driven design frameworks. For automation synthesis, ML integrates polymerization kinetics with structure control and polymerization efficiency, enabling closed-loop systems for autonomous process refinement. In performance prediction, ML deciphers hierarchical architectures relationships with thermal resilience, optoelectronic responses, and mechanical robustness, providing physicochemical theory frameworks for tailored material design. Critical analyses address persistent limitations, including data paucity in specialty polymer classes, interpretability deficits in multimodal architectures, and validation gaps between simulation and experiments. By synergizing generative algorithms with high throughput experimentation, this strategy transcends empirical trial-and-error approaches, establishing a computational design paradigm spanning molecular-to-bulk scales. The resultant synergy between computational intelligence and polymer science not only streamlines material discovery cycles but also unlocks sustainable solutions for energy storage, eco-friendly materials, and adaptive smart systems, heralding a new era of data-driven macromolecular engineering.

聚合物作为现代工业的基础材料，由于结构的复杂性、多功能性要求和可持续性要求，在精密设计和性能改进方面面临着持续的挑战。机器学习（ML）已成为阐明结构-性能相关性和加速聚合物材料发现的变革性工具。这篇综述系统地考察了机器学习在三个领域的应用：通过反应动力学建模的自主合成，将聚合物配置与整体行为联系起来的跨尺度性质预测，以及可持续性驱动的设计框架。对于自动化合成，ML将聚合动力学与结构控制和聚合效率集成在一起，使闭环系统能够自主改进过程。在性能预测中，机器学习破译了与热弹性、光电响应和机械鲁棒性的层次结构关系，为定制材料设计提供了物理化学理论框架。关键分析解决了持续存在的局限性，包括特殊聚合物类别的数据缺乏，多模态架构的可解释性缺陷，以及模拟和实验之间的验证差距。通过将生成算法与高通量实验相结合，该策略超越了经验试错方法，建立了一种跨越分子到体尺度的计算设计范式。计算智能和聚合物科学之间的协同作用不仅简化了材料发现周期，而且还为能源存储、环保材料和自适应智能系统提供了可持续的解决方案，预示着数据驱动的大分子工程的新时代。

Cardiovascular disease (CVD) remains a leading global cause of mortality, underscoring the urgent need for innovative therapeutic solutions. Biodegradable magnesium-based stents (BMgS) have emerged as groundbreaking alternatives for coronary artery disease, offering temporary vascular support with safe biodegradation to minimize complications associated with permanent implants. Over the past decade, significant strides have been made in BMgS research, particularly in material science, advanced manufacturing techniques, and surface modifications. However, challenges such as uncontrolled degradation rates, insufficient mechanical strength, and limited biocompatibility continue to hinder their clinical adoption. This review provides a comprehensive and critical analysis of BMgS development advancements, with a particular focus on in vitro testing methodologies. Core areas include corrosion performance evaluation, mechanical property testing, and biocompatibility assessments, highlighting innovative approaches such as novel corrosion reactors, finite element analysis (FEA), and advanced biological assays. Development strategies center on alloy optimization (Mg-Zn and Mg-RE systems), cutting-edge manufacturing processes, and sophisticated surface modifications, including polymer, inorganic, and composite coatings, all tailored to enhance stent functionality. By synthesizing recent progress, this review not only identifies persistent challenges but also provides actionable insights for overcoming them. These findings serve as a valuable resource for researchers and industry stakeholders, paving the way for next-generation BMgS that strive to revolutionize cardiovascular care and improve patient outcomes.

Decellularized extracellular matrix (dECM) biomaterials and hydrogels have drawn particular attention for tissue development and regeneration of injured or diseased tissues/organs owing to their intrinsic tissue-specific biochemical cues. However, these biomaterials face serious challenges regarding their mechanical strength, structural stability, fast degradation, and difficult handling. These shortcomings indeed alleviate their therapeutic functions as tissue substitutes. Modifying dECM biomaterials with light-responsive agents enables them to establish covalent crosslinks upon UV or visible light exposure. This review aims to elaborate on the current status of photocrosslinking techniques and methodologies applied for dECMs and the underlying mechanisms of action. Herein, we also elucidate the application of light-activated dECM biomaterials in the engineering and regeneration of soft and hard tissues, implantable bioprostheses, translational medicine, disease or tumor modeling, and drug screening platforms. Moreover, the recent advances in the processability of photocrosslinked dECM bioinks for 3D bioprinting scaffolds and tissue-engineered constructs (TECs) with a focus on their bio-functionality are covered. Finally, the current challenges of light-activated dECM biomaterials and potential solutions to address these issues and pave the way for translational medicine are elaborated. The review concludes that the applicability of the light-activated dECM biomaterials holds great promise as a patient-specific healthcare solution.

Chemical looping (CL) is an increasingly important approach for net-zero energy conversion, power generation, and fine chemical production. By leveraging lattice oxygen in solid oxygen carriers (OCs) instead of gas-phase oxygen, a CL process intensifies redox transformations and avoids complex product separation. However, industrial CL processes demand structurally stable and chemically controllable OCs with high oxygen capacity, regulatable reactivity, and structural integrity even under harsh operational conditions. Currently, several key challenges exist: 1) Cation diffusion and agglomeration of OCs during cyclic lattice oxygen release and restoration; 2) sintering and inactivation of OCs under harsh reaction conditions (e.g., high temperatures); and 3) lack of effective OCs towards CL-coupled tandem catalysis. A potential strategy to resolve these challenges is to assemble hierarchical OCs that integrate oxygen storage materials, catalysts and inert supports from the nanoscale. In this regard, this review aims to critically assess the advanced design and synthesis of such hierarchical structures with embedded and core–shell configurations, and then clarify the relationships between the structural hierarchy and superior CL performance over a wide range of applications (from syngas to biomass conversion). The unique roles of confinement effects and strong metal–support interactions in hierarchical OCs are analyzed to explain the enhanced durability and CL activity. Based on current synthesis approaches, this review further identifies the challenges and future perspectives of hierarchical OCs for CL tandem catalysis, e.g. Fischer–Tropsch synthesis, alkane dehydrogenation, and CO₂ hydrogenation, towards CL-based “net-zero” applications.

化学环（CL）是一种越来越重要的零净能源转换、发电和精细化工生产方法。通过利用固体氧载体（OCs）中的晶格氧而不是气相氧，CL过程加强了氧化还原转化，避免了复杂的产物分离。然而，工业CL工艺需要结构稳定，化学可控的OCs，具有高氧容量，可调节的反应性，即使在恶劣的操作条件下也能保持结构完整性。目前存在的主要挑战有：1)循环晶格氧释放和恢复过程中阳离子的扩散和oc的团聚；2)在恶劣的反应条件下（如高温）烧结和oc失活；3)缺乏对cl偶联串联催化有效的OCs。解决这些挑战的一个潜在策略是组装层次化的OCs，将储氧材料、催化剂和纳米级惰性载体整合在一起。在这方面，本文旨在批判性地评估具有嵌入和核壳结构的这种分层结构的先进设计和合成，然后阐明结构层次与广泛应用（从合成气到生物质转化）中优越CL性能之间的关系。分析了约束效应和强金属-支撑相互作用在分层oc中的独特作用，以解释其耐久性和CL活性的增强。基于目前的合成方法，本综述进一步确定了CL串联催化（例如，费托合成、烷烃脱氢和CO2加氢）中分层OCs的挑战和未来前景，以实现基于CL的“净零”应用。

Rare earths (RE) have garnered significant attention in electrocatalysis due to their unique ability to modulate electronic structure of host materials. The gradient orbital coupling (GOC) based on f-p-d orbital interaction has recently been proposed to explain the key reason for RE-enhanced electrocatalysis. However, a systematic review elaborating the critical role of GOC in electrocatalysis remains lacking. Herein, this review presents a timely and comprehensive summary of GOC breakthroughs in RE-based electrocatalysts and highlights their key role in electrocatalysis. It begins by introducing the fundamentals of GOC. We further discuss the most recent progress in tuning the electronic state of metal active centers by GOC for various electrocatalytic reactions including oxygen electrocatalysis, hydrogen evolution, carbon dioxide reduction, nitrogen oxidation and urea oxidation. From GOC insight, this discussion of electrochemical performances and intrinsic catalytic mechanisms favors the construction of RE-evoked structure-performance relationship. At the end, we discuss the challenges and potential future directions for research related to the GOC. We hope this review will inspire novel designs and a deeper understanding of RE-based electrocatalysts.

Porous materials, particularly covalent organic frameworks (COFs), exhibit well-defined porosity, tunable structural features, and high chemical and thermal stability.

多孔材料，特别是共价有机框架（COFs），具有明确的孔隙度，可调的结构特征，以及高的化学和热稳定性。这些固有特性使COFs成为高效功能材料合理设计的极有希望的候选材料，从而吸引了不同科学和工程学科的极大兴趣。然而，原始的COF框架经常受到活性位点和功能部分密度不足的影响，从而限制了它们的实际性能。因此，将金属组件集成到COF架构中已经成为增强其功能的一种有前途的策略。在本文中，我们介绍了一种基于金属物种与碳纤维之间相互作用强度的新分类方案，使现有的金属改性碳纤维材料能够进行系统的组织。该框架从金属-COF相互作用强度的角度阐明了不同金属改性COF材料之间的内在关系和区别，从而促进了对其结构-性能相关性的基本理解，从而促进了对这类有趣材料的深入分析。综述了金属改性COF材料在吸附分离、光催化、电催化、储能、传感、生物医学等方面的研究进展。重点放在结构设计原则，合成方法，表征技术，以及不同的金属修饰COF材料如何影响反应途径和潜在的机制。最后，对金属改性COF材料面临的挑战和未来的研究方向进行了批判性的讨论。

Just with one decade of history (The discovery of Ti₃C₂ − 2011), studies on two-dimensional (2D) transition metal carbides, carbonatites, and nitrides (comprehensively stated as MXenes) vastly expanded from fundamental to applications level. The engineered MXenes are good competitors to 2D materials like graphene, metal–organic frameworks, etc., with widespread applications such as gas sensors, water purification, EMI shielding, energy storage, and catalysts etc. Owing to the 2D layered structure, the intercalation of cations, comprising multivalent ones and polar organic molecules, allows the control of interlayer distance and enables MXenes to be used in water purification and desalination. Besides, MXenes have a high aspect ratio due to the sheet structure, which provides nanochannels as diffusion paths for these applications. In this review, we explored the MXenes as membrane materials for pressure-driven membrane-based water desalination technology and the various physico-chemical modifications of MXene’s structure to enhance desalination performance. We also highlight membrane-desalination metrics, fabrication strategies of membranes, trade-off analysis, and the mechanisms behind enhanced performances due to modifications, which provide essential insights about these materials. Ultimately, we summarize the present challenges and provide the future outlook as the foundation for early researchers.

仅仅十年的历史（Ti3C2 - 2011的发现），二维（2D）过渡金属碳化物、碳酸盐和氮化物（统称为MXenes）的研究从基础到应用水平得到了极大的扩展。经过改造的MXenes是石墨烯、金属有机框架等2D材料的有力竞争对手，在气体传感器、水净化、电磁干扰屏蔽、储能和催化剂等领域有着广泛的应用。由于其二维层状结构，由多价离子和极性有机分子组成的阳离子的插入可以控制层间距离，使MXenes能够用于水净化和海水淡化。此外，由于片状结构，MXenes具有高宽高比，为这些应用提供了纳米通道作为扩散路径。在本文中，我们探讨了MXene作为压力驱动膜基海水淡化技术的膜材料，以及对MXene结构进行各种物理化学修饰以提高海水淡化性能。我们还强调了膜淡化指标，膜的制造策略，权衡分析以及由于修改而增强性能的机制，这些都为这些材料提供了重要的见解。最后，我们总结了当前面临的挑战，并提出了未来的展望，作为早期研究的基础。

Rare-earth Ce³⁺ ions activated garnet phosphors, as one of the most promising luminescent materials, have received tremendous attention for their potential applications in phosphor-converted white light-emitting diodes (pc-WLEDs), due to their high absorption efficiency, remarkable multi-color emissions, broadband emission spectra, high luminescence efficiencies, and excellent thermal stability. In this paper, recent advances in the developments of Ce³⁺-activated garnet phosphors for pc-WLEDs are reviewed. Firstly, the working principle of pc-WLEDs, the structural composition of garnet, the photoluminescence theory of Ce³⁺ ions, as well as the dominated factors affecting thermal stability and related thermal quenching mechanisms are highlighted. Secondly, several different synthesis methods of Ce³⁺-activated garnet phosphors are thoroughly elaborated, and the effects of these methods on the micro/nanoscale morphologies and luminescence properties are discussed. Thirdly, photoluminescence characteristics and thermal stability, as well as color stability of various color-emitting Ce³⁺-activated garnet phosphors together with their functional applications in pc-WLEDs are systematically summarized.

Classical rubbers and elastomers are normally prepared via a crosslinking process such as vulcanization, which can produce permanent covalently crosslinked structures and endows mechanical robustness, chemical resistance and thermal stability. However, the permanent covalently crosslinked networks make rubbers and elastomers cannot be reprocessed, reshaped or recycled, causing serious pollution and negative impacts on the environment. The design of dynamic covalent crosslinked structures in polymers brings new properties to classical rubber and elastomer materials, in particular in terms of thermal responses, reprocessability and recycling abilities. In recent years, there has been a growing interest in the design and synthesis of dynamic crosslinked polymers. In this review, the designs, characterizations, and utilizations of dynamic crosslinked elastomers and rubbers are summarized, focusing on the design and synthesis of dynamic crosslinked elastomers and rubbers with sustainability and recyclability, followed by an overview of the applications of dynamic crosslinked elastomers and rubbers. Furthermore, through the tuning and controlling on the dynamic crosslinked structure variedly, some functional behaviors can be realized. To declare and promote the consequence and potential utilization of the dynamic crosslinked elastomers and rubbers, perspectives and suggestions are presented for future research on the design, synthesis, and process strategies of dynamic crosslinked elastomers and rubbers.

经典橡胶和弹性体通常是通过硫化等交联工艺制备的，它可以产生永久的共价交联结构，并赋予其机械坚固性、耐化学性和热稳定性。然而，永久共价交联网络使得橡胶和弹性体不能再加工、重塑或回收，对环境造成严重污染和负面影响。聚合物中动态共价交联结构的设计为经典橡胶和弹性体材料带来了新的性能，特别是在热反应、再加工和回收能力方面。近年来，人们对动态交联聚合物的设计和合成越来越感兴趣。本文综述了动态交联弹性体和橡胶的设计、表征和应用，重点介绍了具有可持续性和可回收性的动态交联弹性体和橡胶的设计和合成，然后概述了动态交联弹性体和橡胶的应用。此外，通过对动态交联结构进行不同的调谐和控制，可以实现一些功能行为。为了阐明和促进动态交联弹性体和橡胶的重要性和潜在的应用，对动态交联弹性体和橡胶的设计、合成和工艺策略的未来研究提出了展望和建议。
