Titanium (Ti) alloys have emerged as one of the most sought-after metallic materials for additive manufacturing (AM). This originates from the unparalleled synergy of AM's capability to produce intricate geometries and the superior mechanical properties and corrosion resistance inherent to Ti alloys. Despite these benefits, AM Ti alloys continue to face persistent challenges that hinder their in-service reliability and broader adoption. Unlike conventionally manufacturing, AM introduces unique microstructural features such as non-uniform residual stresses and inhomogeneous grain structures, which often result in pronounced variability in material properties. Crucially, this variability underscores an urgent need for thorough performance evaluation of AM-produced parts, especially for critical structural applications where safety and durability are paramount. Previous reviews have broadly addressed AM Ti alloys' static properties and general processing challenges. In contrast, this review takes a comprehensive approach to examine the dynamic performance aspects—specifically, fatigue and damage tolerance—which remain insufficiently summarized yet vital for real-world applications. It deepens into the underlying mechanisms governing these properties, emphasizing the influence of key defects (e.g., porosity, segregation) as well as microstructural characteristics such as grain morphology and residual stresses. Additionally, this work expands the discussion to assess the behavior of AM Ti alloys under extreme environmental conditions (high-temperature and cryogenic operations), which are increasing demand in the automotive and energy sectors. By providing a detailed evaluation of these critical aspects, this review aims to bridge existing knowledge gaps, offering actionable insights to refine AM Ti alloy processing and enhance their structural reliability for demanding applications.

钛（Ti）合金已成为增材制造（AM）中最受欢迎的金属材料之一。这源于AM生产复杂几何形状的能力以及钛合金固有的优越机械性能和耐腐蚀性的无与伦比的协同作用。尽管有这些优点，AM钛合金仍然面临着持续的挑战，阻碍了它们的使用可靠性和更广泛的应用。与传统制造不同，增材制造引入了独特的微观结构特征，如不均匀的残余应力和不均匀的晶粒结构，这通常会导致材料性能的显著变化。至关重要的是，这种可变性强调了对am生产部件进行全面性能评估的迫切需要，特别是对于安全性和耐久性至关重要的关键结构应用。以前的评论广泛地讨论了AM Ti合金的静态性能和一般的加工挑战。相比之下，这篇综述采用了一种全面的方法来研究动态性能方面，特别是疲劳和损伤容限，这些方面仍然没有得到充分的总结，但对实际应用至关重要。它深入到控制这些性能的潜在机制，强调关键缺陷（例如，孔隙度，偏析）以及微观结构特征（如晶粒形态和残余应力）的影响。此外，这项工作扩大了讨论范围，以评估AM Ti合金在极端环境条件下（高温和低温操作）的行为，这在汽车和能源部门的需求不断增加。通过对这些关键方面的详细评估，本综述旨在弥合现有的知识差距，提供可操作的见解，以改进AM钛合金的加工，并提高其结构可靠性，以满足苛刻的应用。

Traditional artificial vision systems are constrained by the von Neumann architecture, which segregates the components responsible for image perception, memory, and processing. This segregation results in low integration, high energy consumption, and inefficient processing. In contrast to traditional vision systems, bio-inspired neuromorphic vision systems utilize photoelectric memristors to integrate sensing, memory, and computation, enabling parallel processing of visual information. These systems can not only emulate the retina direct response to light signals to perform image preprocessing tasks, such as noise reduction and contrast enhancement, but also replicate the image recognition and classification functions of the brain visual cortex. Additionally, they offer a reliable hardware platform to enable progress in complex artificial vision technologies. This review primarily summarizes the research progress in artificial visual systems based on photoelectric memristors, offering an overview of their device structure, working mechanisms, material and device design, as well as their applications and challenges in artificial vision. This work is intended to analyze new technologies and their future outlook, focusing on how they may fuel innovation and facilitate extensive adoption.

To generate an infinite spectrum of vibrant colors, both nature and human can exquisitely manipulate matter and its interactions with light through finely screened materials, optimally designed micro- and nanostructures, and precisely regulated processes. Even in today’s digital world, rewritable paper-based stimuli-responsive chromic materials remain essential to socioeconomic development and the advancement of civilization, leading to the creation of sophisticated optical materials and devices. In this review, we systematically explore various types of stimuli-responsive chromic papers, categorized by their color-changing mechanisms, including thermo-, photo-, hydro-, mechano-, electrochromism, and others such as light emission, structural color, electronic chromism, and coordination chemistry. Our aim is to comprehensively elucidate the relationships among structure, properties, functions, and applications of these color-changing systems across disciplines, demonstrating their diverse applications in dynamic color displays, inkless printing, information encryption, anti-counterfeiting technologies, smart home products, healthcare, and diagnostic systems. Furthermore, we highlight current challenges and future perspectives in the design and fabrication of sustainable rewritable papers. This review is expected to attract significant interest from the advanced materials community, as well as photonic devices, nanotechnology, and engineering, thereby fostering significant breakthroughs in both scientific investigations and commercial applications.

Photocatalytic CO₂ reduction offers a promising route to address climate change while producing sustainable solar fuels. However, achieving efficient conversion under low CO₂ concentrations, especially at atmospheric levels near 400 ppm, remains highly challenging due to sluggish kinetics, limited accessibility of active sites, and complex multi-electron pathways. This review critically evaluates recent advances in photocatalyst design and application-oriented strategies that seek to overcome these limitations. High-surface-area frameworks such as MOFs and COFs, defect-engineered nanosheets, and conjugated porous polymers have been developed to enhance CO₂ adsorption and charge carrier dynamics. Additional strategies to improve light harvesting and charge separation include noble metal modification and heterojunction construction. Application-oriented approaches are also highlighted, including the integration of photocatalysis with direct air capture and the design of catalysts that maintain activity in the presence of O₂, SO_X, and other impurities. Despite progress, CO remains the dominant product under dilute conditions, while selective formation of C₂₊ products remains rare and energy intensive. Future progress will require rationally designed hierarchical architectures, multifunctional catalysts, and in situ mechanistic investigations. Artificial intelligence and high-throughput screening are emerging as powerful tools for accelerating discovery. Together, these strategies define a roadmap toward scalable CO₂ conversion technologies under realistic conditions.

光催化二氧化碳还原为解决气候变化问题提供了一条有希望的途径，同时生产可持续的太阳能燃料。然而，在低二氧化碳浓度下，特别是在大气浓度接近400 ppm时，由于动力学缓慢，活性位点的可及性有限，以及复杂的多电子途径，实现高效转化仍然是极具挑战性的。这篇综述批判性地评估了光催化剂设计和面向应用的策略的最新进展，以寻求克服这些限制。高表面积框架，如mof和COFs、缺陷工程纳米片和共轭多孔聚合物已经被开发出来，以增强二氧化碳吸附和载流子动力学。改善光收集和电荷分离的其他策略包括贵金属修饰和异质结的构建。应用导向的方法也得到了强调，包括光催化与直接空气捕获的集成，以及在O2， SOX和其他杂质存在下保持活性的催化剂的设计。尽管取得了进展，但CO仍然是稀条件下的主导产物，而C2+产物的选择性形成仍然很少，而且是能源密集型的。未来的进展将需要合理设计分层结构、多功能催化剂和原位机理研究。人工智能和高通量筛选正在成为加速发现的有力工具。总之，这些策略定义了在现实条件下可扩展的二氧化碳转换技术的路线图。

Persistent organic pollutants (POPs) pose a growing environmental and public health crisis, necessitating the development of advanced, sustainable remediation strategies. Carbon nanostructures (CNSs)—including fullerenes, carbon nanotubes (CNTs), graphene, quantum dots (CQDs/GQDs), and nanodiamonds—offer unprecedented photocatalytic potential owing to their tunable dimensionality (0D–3D), high surface area, and exceptional charge transport. This review delivers a mechanistically driven and application-oriented perspective on CNS-based photocatalysts, emphasizing structure–property correlations, targeted surface engineering, and advanced synthesis routes. We highlight how heteroatom doping, defect manipulation, and covalent/non-covalent functionalization modulate band gaps, enhance light harvesting, and accelerate interfacial charge transfer. At the same time, type-II and Z-scheme heterojunction architectures preserve redox potential and minimize recombination. Uniquely, this article integrates green synthesis strategies, computational modeling, machine learning, and toxicity assessments into a unified design roadmap, offering insights beyond conventional literature surveys. Remaining challenges—such as synthesis reproducibility, dispersibility, photostability, and environmental risk—are critically analyzed, with strategic recommendations for scalable, low-cost, and safe CNS deployment. By bridging mechanistic fundamentals with translational pathways, this review positions CNSs as next-generation, high-performance platforms for large-scale photocatalytic water purification and pollutant degradation.

As an efficient approach, electrolyte optimization has been extensively studied and leads to significant improvements in battery performance. Compared with the specific formulations, the interactions between electrolyte components and the resulting solvation structures have attracted widespread attention. This is because they provide deep insights into the solvation structure-property relationships of electrolytes. Faced with rapid progress in understanding the various interactions within electrolyte in recent years, it is crucial to promptly summarize these advances in detail and establish a theoretical framework. Such a framework will aid in comprehending the essence behind the performance enhancement of numerous existing formulations and guiding future electrolyte design. In this review, we begin by summarizing the processes related to ion transport and interfacial chemistry in electrolytes, along with their relationship to electrolyte solvation structures. Building on this foundation, detailed analysis is provided on how the various interactions within the electrolyte influence the solvation structure and consequently impact the above two key functions. Furthermore, some conflicting aspects and feasible strategies in interaction regulation are discussed. With a comprehensive and deep understanding of the fundamental interactions and solvation structure-property relationships, bottom-up electrolyte design can be achieved, improving the efficiency and precision of electrolyte development.

The convergence of materials science and biomedicine has driven a paradigm shift towards personalized, responsive medical solutions. This review focuses on three pivotal classes of stimuli-responsive smart materials: shape memory polymers (SMPs), stimuli-responsive hydrogels (SRHs), and liquid crystal elastomers (LCEs), for transformative biomedical applications. SMPs offer programmable shape recovery triggered by stimuli (e.g., temperature, light), enabling minimally invasive procedures and adaptive scaffolds. SRHs combine the biocompatibility and softness of traditional hydrogels with dynamic, multifunctional responses to environmental cues like heat, light, or pH. LCEs uniquely integrate liquid crystal order with elastomeric networks, exhibiting reversible deformation and actuation ideal for biomimetic prosthetics and tissue engineering. Critically, the emergence of 4D printing technology, integrating these SRMs with additive manufacturing, overcomes limitations of static fabrication by enabling the creation of structures that dynamically transform in situ under specific triggers. This allows precise spatiotemporal control for complex, personalized medical devices across scales.

With the increasing severity of urban heat islands, personal thermal management (PTM) has emerged as a critical solution for maintaining human thermophysiological comfort in dynamic environments. Traditional air conditioning systems are energy-intensive and lack individualized control, highlighting the need for efficient, low-energy PTM strategies. Current PTM materials often operate in static modes, limiting their adaptability to varying conditions. To overcome this, we developed a Janus-structured humidity-photothermal actuator (TpPa-SO₃H/Ag@M) by integrating a TpPa-SO₃H covalent organic framework (COF) for rapid water transport and a silver nanoparticle (AgNP)-intercalated MXene (Ag@M) for humidity gradient formation and enhanced photothermal conversion. The COF layer facilitates moisture accumulation, while the Ag@M laminar structure delays water diffusion, enabling a sensitive humidity response. AgNPs expand the MXene interlayer spacing, improving water uptake and response efficiency by triple compared to initial TpPa-SO₃H/MXene systems, while also preventing structural collapse during cycling. Additionally, AgNPs enables strong solar absorption, boosting photothermal performance. Under combined humidity and light stimulation, the Janus actuator exhibits dynamic bending, enabling autonomous sweat evaporation and body temperature regulation without external energy input. This dual-responsive design offers a promising approach for adaptive, energy-efficient PTM in extreme environments.

随着城市热岛的日益严重，个人热管理（PTM）已成为动态环境中维持人体热生理舒适的关键解决方案。传统的空调系统是能源密集型的，缺乏个性化的控制，突出了对高效、低能耗的PTM策略的需求。目前的PTM材料通常在静态模式下工作，限制了它们对变化条件的适应性。为了克服这一问题，我们开发了一种jans结构的湿热执行器（TpPa-SO₃H/Ag@M），通过集成用于快速水输送的TpPa-SO₃H共价有机框架（COF）和用于形成湿度梯度和增强光热转换的银纳米颗粒（AgNP）嵌入MXene （Ag@M）。COF层有利于水分积累，而Ag@M层流结构则延迟水分扩散，从而实现敏感的湿度响应。AgNPs扩大了MXene层间距，与最初的TpPa-SO₃H/MXene系统相比，吸水率和响应效率提高了三倍，同时还防止了循环过程中的结构坍塌。此外，AgNPs具有很强的太阳能吸收能力，提高了光热性能。在湿度和光线的联合刺激下，Janus致动器表现出动态弯曲，无需外部能量输入即可实现自主汗液蒸发和体温调节。这种双响应设计为极端环境下的自适应节能PTM提供了一种有前途的方法。

The performance of inverted perovskite solar cells (PSCs) employing bio-inspired chlorophyll (Chl)-based hole transport materials (HTMs) is frequently limited by interfacial losses and non-radiative recombination. We address this challenge through a molecular-level interface engineering strategy, implementing a novel dopant-free, dual-function polymeric HTM. Synthesized via electrochemical polymerization, the polymeric copper serinyl pyropheophorbide-a features an extended π-conjugated framework for efficient hole extraction. Subsequent surface modification with trifluoroacetate anions at the amino acid terminals generates Lewis base sites that coordinate with undercoordinated Pb^2 + ions at the HTM/perovskite interface, enabling simultaneous defect passivation and crystallization control. The optimized devices achieve a champion power conversion efficiency (PCE) of 24.5 %—a record for Chl-based HTMs—with an exceptional fill factor of 85.3 %. Crucially, these PSCs demonstrate outstanding operational stability, retaining 93.2 % of their initial PCE after 2700 h under ambient conditions (unencapsulated). By elucidating the structure-property-performance relationships, this work not only underscores the significant potential of dopant-free Chl-derived materials for next-generation photovoltaics but also provides generalizable insights into multifunctional interfacial modification for highly efficient and stable perovskite devices.
