The demand for developing advanced hybrid materials with improved functions and performance is rising due to the current challenges in the environmental and energy fields. Hybridization of nanomaterials can address the shortcomings of individual components and afford composite nanomaterials with improved performance through synergistic effects. MXenes are among the growing families of inorganic two-dimensional (2D) materials with unique properties such as high electrical conductivity, hydrophilicity, easy processability, and excellent photothermal and electrochemical characteristics. Some limitations of MXenes, including poor chemical stability in oxidative conditions and low porosity due to restacking the 2D flakes, could hinder their potential in environmental applications. On the other hand, covalent organic frameworks (COFs) are highly porous organic networks but with primary shortcomings of low electrical conductivity and poor processability. Combining the metallic conductivity and excellent photothermal and electrochemical properties of MXenes with the high porosity of COFs enables the formation of COF@MXene nanomaterials with improved properties. Here, we provide a comprehensive review of the strategies utilized for designing and fabricating COF@MXene heterostructures through chemical and physical hybridization. The synergistic effects of hybridization are discussed for diverse applications, including catalysis, energy storage materials, sensors, water purification, and anti-corrosion coatings. Finally, the future outlook of the COF@MXenes, their challenges and possible solutions for these challenges are discussed.

由于当前环境和能源领域的挑战，对开发功能和性能改进的先进混合材料的需求正在上升。纳米材料的杂交可以解决单个组分的缺点，并通过协同效应提供性能提高的复合纳米材料。MXenes是不断发展的无机二维（2D）材料家族之一，具有高导电性、亲水性、易加工性、优异的光热和电化学特性等独特性能。MXenes的一些局限性，包括在氧化条件下化学稳定性差，以及由于二维薄片的重新堆积而导致的低孔隙率，可能会阻碍其在环境应用中的潜力。另一方面，共价有机框架（COFs）是高多孔性的有机网络，但主要缺点是电导率低，可加工性差。将MXenes的金属导电性和优异的光热电化学性能与COFs的高孔隙率相结合，可以形成具有改进性能的COF@MXene纳米材料。在这里，我们提供了利用化学和物理杂交设计和制造COF@MXene异质结构的策略的全面回顾。讨论了杂化的协同效应在催化、储能材料、传感器、水净化和防腐涂料等方面的应用。最后，对COF@MXenes的未来前景、面临的挑战以及可能的解决方案进行了讨论。

Multi-atom catalysts (MACs) can break the limitation of single-atom catalysts (SACs) by introducing metal clusters, presenting a more diversified way in the composition, structure and performance of multi-atom sites, and utilizing the synergistic effect of multi atoms and metal-support interactions to jointly regulate the electronic structure of active sites, which endow them with advantageous electrocatalytic performance and unique reaction mechanism and expand new opportunities for the electrocatalytic field. Here, we summarize synthesis strategies, in situ structural characterization and the features reflecting structure-activity relationships of MACs with respect to composition and configuration, electron distribution as well as multiple functional effects. Then, the design principles of high-performance MACs are accentuated, involving multi-atom sites, coordination environments, interfacial defects, reaction media, and special thoughts including bio-inspired design and computing-learning-prediction. Subsequently, the applications in energy storage and conversion technologies are provided. Lastly, we conclude with some personal thoughts and perspectives on the growth and development of MACs in their nascent state.

Molecular doping is an effective approach to modulate the electrical properties of polymer semiconductors. However, doping efficiency is often limited by incomplete charge transfer between polymers and dopants. Herein, we designed three polymers, Pg₃2T-Se, Pg₃2T-T, P2T-Se, with tailored highest occupied molecular orbital (HOMO) levels by combining selenophene/thiophene backbone and alkyl/oligoethylene glycol side chains. It is found that the degree of charge transfer is strongly dependent on the energy offset between polymer and dopant (F4TCNQ). Pg₃2T-Se with a shallowest HOMO level shows completely integer charge transfers (ICT) state, even dopant dianions (double doping) is detected at a low dopant concentration, while both ICT state and charge transfer complex (CTC) state are observed in doped P2T-Se with a deepest HOMO level. A remarkably electrical conductivity of Pg₃2T-Se up to 1135.9 S cm⁻¹ is obtained via single-solution doping, which is attributed to its high carrier concentration. The microstructure evolution of polymer packing upon doping further indicate that the dopants insert into the side chain will facilitate the generation of ICT states. Our results demonstrate that a large energy offset, together with dopant located in the side chains (away from the backbone), promotes high doping level, thereby achieving high conductivity.

分子掺杂是调制聚合物半导体电性能的有效途径。然而，掺杂效率往往受到聚合物和掺杂剂之间电荷转移不完全的限制。在此，我们设计了三种聚合物，Pg32T-Se, Pg32T-T, P2T-Se，通过结合硒苯/噻吩主链和烷基/低聚乙二醇侧链来定制最高占据分子轨道（HOMO）水平。发现电荷转移程度强烈依赖于聚合物和掺杂剂（F4TCNQ）之间的能量偏移。最浅HOMO能级的Pg32T-Se表现为完全整数电荷转移（ICT）状态，在低掺杂浓度下甚至可以检测到掺杂离子（双掺杂），而在最深HOMO能级掺杂的P2T-Se中可以观察到ICT状态和电荷转移复合物（CTC）状态。通过单溶液掺杂，Pg32T-Se的电导率可达1135.9 S cm−1，这是由于其载流子浓度高。聚合物填料在掺杂后的微观结构演变进一步表明，掺杂剂插入侧链会促进ICT态的生成。我们的研究结果表明，大的能量偏移，以及位于侧链（远离主链）的掺杂剂，促进了高掺杂水平，从而实现了高电导率。此外，由于低功耗和提高灵敏度，高导电性聚合物薄膜对传感器具有吸引力。掺f4tcnq的Pg32T-Se作为柔性压阻传感器的有源层，具有较高的灵敏度和循环稳定性，在可穿戴设备中具有广阔的应用前景。

In-situ alloying by additive manufacturing (AM) is a versatile and efficient approach for the rapid development of new materials. However, its successful implementation critically depends on achieving effective and homogeneous alloying during the process — an outcome that is highly sensitive to the process parameters and remains challenging to predict. In this study, a process map incorporating the degree of in-situ alloying was developed for laser powder bed fusion (LPBF) of a titanium-tantalum binary alloy with 30 wt% tantalum (Ti-30Ta) by correlating single-track melt pool characteristics with bulk sample properties through the integration of machine learning and analytical modelling. This approach coupled and quantified the relationship between the melt pool mode and mechanical properties, refining the process window for the Ti-30Ta alloy system. Under the defined process window, fabricated Ti-30Ta bulk samples exhibited optimised mechanical properties, with an ultimate tensile strength (UTS) of 745.8 MPa and an elongation of 16.9 %. Synchrotron X-ray diffraction analysis confirmed that the microstructure is predominantly composed of orthorhombic α″ phase. Furthermore, the samples demonstrated enhanced biocompatibility and a favorable balance between structural density and alloy homogeneity, underscoring their broad application potential. Beyond its direct implications for Ti-30Ta alloy, this study establishes a transferable framework for in-situ alloying process maps development across various alloy systems, paving the way for more advanced alloy development and manufacturing strategies in the field of in-situ alloying AM and beyond.

原位合金化增材制造（AM）是一种快速开发新材料的通用而高效的方法。然而，它的成功实施关键取决于在过程中实现有效和均匀的合金化-这一结果对工艺参数高度敏感，并且仍然具有挑战性预测。在本研究中，通过集成机器学习和分析建模，将单轨熔池特征与体样特性相关联，开发了含有30 wt%钽（Ti-30Ta）的钛-钽二元合金的激光粉末床熔合（LPBF）的过程图，其中包含了原位合金化程度。该方法耦合并量化了熔池模式与力学性能之间的关系，细化了Ti-30Ta合金体系的工艺窗口。在确定的工艺窗口下，制备的Ti-30Ta体试样具有最佳的力学性能，其极限抗拉强度（UTS）为745.8 MPa，伸长率为16.9 %。同步加速器x射线衍射分析证实，其微观结构主要由正交α″相组成。此外，样品具有较强的生物相容性，并在结构密度和合金均匀性之间取得了良好的平衡，具有广阔的应用潜力。除了对Ti-30Ta合金的直接影响外，本研究还为跨各种合金系统的原位合金化工艺图开发建立了一个可转移的框架，为原位合金化AM等领域更先进的合金开发和制造策略铺平了道路。

Biological tissues, especially human skin, exhibit remarkable abilities to sense, adapt, and interface with surrounding environments, driving a significantly increasing interest in creating synthetic materials that can mimic these functions. Electrically conductive hydrogels (ECHs) represent a promising class of bioinspired materials poised to reshape the landscape of flexible mechanosensing technologies. Their intrinsic softness, biocompatibility, and tunable electrical conductivity enable them to serve as skin-like interfaces, translating mechanical stimuli (e.g., strain or pressure) into electronic signals. Despite the rapid development of ECHs, there still lacks a comprehensive understanding of the rational design principles, key functionalization strategies, and novel engineering methods, for achieving advanced mechanosensors. New applications in health monitoring, soft robotics, human-machine interactions, and plant monitoring also increasingly demand better sensitivity, durability, multifunctionality, and environmental stability of mechanosensors. This review consolidates the latest advances in ECH-based flexible mechanosensors, systematically analyzes the materials chemistry and mechanics that underpin their performance, and highlights the state-of-the-art fabrication approaches that expand their potential. By examining the principles and progress of this rapidly evolving field, we provide insights not only as a current benchmark for ECH-based sensor technologies but also as a strategic guide, illuminating pathways for future breakthroughs that can address pressing practical challenges.

生物组织，尤其是人类皮肤，表现出非凡的感知、适应和与周围环境交互的能力，这促使人们对创造能够模仿这些功能的合成材料的兴趣显著增加。导电水凝胶（ECHs）代表了一类有前途的生物启发材料，准备重塑柔性机械传感技术的景观。它们固有的柔软性、生物相容性和可调节的导电性使它们能够作为皮肤样的界面，将机械刺激（例如，应变或压力）转换为电子信号。尽管ECHs发展迅速，但仍缺乏对合理设计原则、关键功能化策略和新颖工程方法的全面理解，以实现先进的机械传感器。在健康监测、软机器人、人机交互和工厂监测方面的新应用也越来越要求机械传感器具有更好的灵敏度、耐用性、多功能性和环境稳定性。本文综述了基于ech的柔性机械传感器的最新进展，系统地分析了支撑其性能的材料化学和力学，并强调了扩大其潜力的最先进的制造方法。通过研究这一快速发展领域的原理和进展，我们提供的见解不仅是基于ech的传感器技术的当前基准，而且是战略指南，为未来的突破指明了道路，可以解决紧迫的实际挑战。
