Inorganic luminescent materials are highly demanded for solid-state white lighting. 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. Last, the remaining challenges and future development prospects of Ce³⁺-activated garnet phosphors in solid-state lighting are provided.

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。

Bacterial infections threaten global human health, driving the rapid development of antibacterial materials over the past two decades. However, the clinical application is limited due to the rapid presence of antibiotic-resistant bacteria and the brutal penetration of biofilm. ’Smart’ responsive antibacterial materials (SRAMs) that respond to endogenous/exogenous stimuli to release antibacterial factors are appealing therapeutic agents for developing next-generation antibacterial materials. Those materials can evade existing mechanisms associated with acquired drug resistance and could also provide an alternative strategy to treat biofilms due to their spatiotemporal controllability and negligible side effects. SRAMs have emerged as a promising tool to combat bacterial infections that are difficult to treat. To better understand the interaction between SRAMs and biological tissues, this review highlights the mechanisms underlying SRAM-mediated eradication of both planktonic bacteria and biofilms and recent advances in designing SRAMs that respond to internal/external stimuli. Meanwhile, we also summarize the latest progress in the development of SRAMs. Properties of internal- or external-stimuli-responsive smart antibacterial materials are outlined, and we also discuss the potential features required for antibacterial applications of various infectious diseases. Furthermore, it also discussed the current challenges and future prospects, particularly emphasizing clinical translation for these smart antimicrobial platforms.

细菌感染威胁着全球人类健康，推动了抗菌材料在过去二十年中的快速发展。然而，由于耐药细菌的快速存在和生物膜的残酷渗透，临床应用受到限制。“智能”反应性抗菌材料（sram）响应内源性/外源性刺激释放抗菌因子，是开发下一代抗菌材料的有吸引力的治疗剂。这些材料可以逃避与获得性耐药相关的现有机制，并且由于其时空可控性和可忽略的副作用，也可以提供治疗生物膜的替代策略。sram已经成为对抗难以治疗的细菌感染的一种很有前途的工具。为了更好地理解sram与生物组织之间的相互作用，本文重点介绍了sram介导的浮游细菌和生物膜根除的机制，以及设计响应内外刺激的sram的最新进展。同时，我们也总结了sram的最新发展进展。概述了内部或外部刺激响应智能抗菌材料的特性，并讨论了各种传染病抗菌应用所需的潜在特征。此外，还讨论了当前的挑战和未来的前景，特别强调了这些智能抗菌平台的临床转化。

Pharmacotherapy is the core approach for treating various brain diseases. However, the intricate anatomical structure and the blood–brain barrier (BBB) of the brain present challenges for intracerebral drug delivery and therapeutic efficacy. Although systemic administration and surgical interventions can alleviate symptoms, they are limited by low therapeutic effects and potential adverse side effects. Moreover, due to their complex pathogenesis, insidious development, and deep-seated lesions, brain diseases are difficult to diagnose accurately. To address these challenges, there is an urgent need to develop intelligent nanocarriers that can efficiently load drugs and penetrate the BBB for precise therapy of brain diseases. In this connection, micro/nanorobots (MNRs) are multifunctional drug carriers at the micro-nano scale, which possess exceptional penetration and targeting capabilities. Employing externally powered propulsion or chemical self-propulsion, MNRs can navigate in the brain and cross the BBB. This review comprehensively summarizes the recent advances and future outlook of smart MNR drug delivery systems for brain disease treatment. It covers broad topics from nanocarriers to active smart MNRs. Furthermore, it elucidates the therapeutic mechanisms of these smart MNR drug delivery systems in brain diseases based on pathogenesis and pathology. Our aim is to provide a reference for designing and developing novel smart MNRs for drug delivery in the brain, paving the way for their clinical applications in treating brain diseases.

药物治疗是治疗各种脑部疾病的核心方法。然而，大脑复杂的解剖结构和血脑屏障（BBB）对脑内药物传递和治疗效果提出了挑战。虽然全身给药和手术干预可以缓解症状，但由于治疗效果低和潜在的不良副作用，它们受到限制。此外，由于其发病机制复杂、发展隐匿、病灶深，脑部疾病难以准确诊断。为了解决这些挑战，迫切需要开发能够有效装载药物并穿透血脑屏障的智能纳米载体，以精确治疗脑部疾病。在这方面，微/纳米机器人（MNRs）是微纳米尺度上的多功能药物载体，具有卓越的渗透和靶向能力。利用外部动力推进或化学自我推进，磁磁共振可以在大脑中导航并穿过血脑屏障。本文综述了脑疾病治疗中智能MNR给药系统的最新进展及未来展望。它涵盖了从纳米载体到主动智能磁阻的广泛主题。此外，从发病机制和病理角度阐明了这些智能MNR给药系统在脑部疾病中的治疗机制。我们的目的是为设计和开发新型脑内药物传递智能核磁共振提供参考，为其在脑疾病治疗中的临床应用铺平道路。

Over the past few decades, various antifogging strategies and preparation methods have been proposed. Unfortunately, a surface with a single antifogging function cannot achieve a wide range of practical applications. For example, medical endoscopes require antifogging and antibacterial capabilities to improve diagnostic accuracy and safety. Inspired by the near-perfect multifunctional properties of natural creatures, antifogging materials with specific functions have drawn more and more attention owing to their promising and wide applications. However, the design of bioinspired antifogging surfaces with broad applicability still presents some challenges, such as the integration of multifunctional properties, and the optimization of preparation routes. In this review, beginning with the fogging mechanism and wettability theory, the latest antifogging surface materials and pattern designs are analyzed in detail and critically evaluated. The natural biomaterials with multifunctional characteristics are summarized, and the integration mechanism and design difficulties of the four multifunctional characteristics are then emphatically analyzed. Based on artificial intelligence (AI) assisted design optimization, we introduce the neural network into the bionic multifunction antifogging path realization for the first time and summarize the antifogging prototype and antifogging multifunction database.

Inspired by the near-perfect multifunctional properties of natural creatures, antifogging materials with specific functions have drawn more and more attention owing to their promising and wide applications. However, the design of bioinspired antifogging surfaces with broad applicability still presents some challenges, such as the integration of multifunctional properties, and the optimization of preparation routes.

Lignocellulose offers significant promise as a renewable and environmentally sustainable material for construction, while its inherent combustibility poses a major challenge to its widespread application, especially in fire-sensitive environments. In this review, the combustion behavior of lignocellulose and the key mechanisms underlying its flame-retardant strategies are examined. Various classes of flame retardants (FRs), categorized based on the functional elements, are discussed in terms of their flame-retardant mechanisms and interactions with lignocellulosic substrates. Emerging approaches that integrate FRs are explored and compared, with a focus on enhancing flame resistance while minimizing their adverse effects on material properties. Finally, the review concludes with an outlook on current challenges and future research directions, shedding the light to develop more effective, durable, and sustainable flame-retardant solutions for lignocellulose-based materials.

Triptycene, a member of a distinct class of aromatic compounds called iptycenes, has garnered significant attention across various research domains. In recent years, triptycene and its derivatives have emerged as valuable and efficient building blocks for the design and synthesis of novel porous materials with tailored structures and properties. Porous organic polymers (POPs) based on triptycene are organic macromolecules regarded as emerging materials because of their high carbon content, high specific surface area, tunable porosity, low density, high chemical and thermal stability and variable composition. Triptycene-based POPs have demonstrated their competitiveness in various applications, including but not limited to gas storage and separation, water treatment, and catalysis applications. This review comprehensively summarizes recent research on triptycene-based porous organic polymers in materials chemistry.

Bioprinting that can quickly generate custom-shaped organ-like constructs opens up a new horizon for tissue engineering and regenerative medicine. The importance of bioinks cannot be overemphasized in advancing bioprinting development. Superior to conventional static bioink, dynamic bioink, mimicking the natural extracellular matrix, possesses reversible dynamic molecular networks that provide cellular activity and growth and thus enhance the maturation of bioprinted organ-like constructs, which has gained lots of attention and developed rapidly in the past decade. This paper completely summarizes the progress of dynamic bioink in bioprinting. First, we outline the molecular design principle of dynamic bioinks, involving two main patterns: supramolecular force and reversible chemical bonding. Then, key factors of dynamic bioinks in advancing bioprinting, including printability, structural stability, and modulation of cell behavior, are highlighted. Finally, the review further discusses the challenges and perspectives in fabricating tissues and organs with dynamic bioinks, aiming to offer an illuminating insight into bioprinting.
