The central challenge in advancing solid-state energy conversion is the discovery of materials capable of decoupling the intrinsically coupled thermoelectric parameters. While existing layered ionic materials, such as hexagonal Mg3Sb2, exhibit structural anisotropy, they often lack the requisite directional transport and suffer from imbalanced performance at different doping conditions. To address this limitation, we introduce a general design principle, namely the cation-stabilized monolayer network principle. This strategy conceptually segregates the crystal structure into tunable building blocks, which facilitates the rational engineering of new phases with customized anisotropy. Utilizing this principle, we computationally discovered three novel compound categories: tetragonal CICIIAV ternaries, tetragonal CII3AV2 binaries, and orthorhombic CICII2AV2 ternaries. A systematic high-throughput screening of 370 candidates identified 26 thermodynamically stable materials. We confirm the strong anisotropy in both electron and phonon transport achieved in these phases, exemplified by CsMgBi (a CICIIAV compound) which demonstrates an ultra-high anisotropy in the directional thermal conductivities of ρκ = 3.5. Moreover, the identification of tetragonal β-Mg3Sb2 (a CII3AV2 compound) as a superior p-type material addresses a significant performance deficit present in the prevailing hexagonal Mg3Sb2. This work validates the charged monolayer stabilization principle as a powerful approach for the rational discovery of novel, highly anisotropic, and high-performance ionic layered thermoelectrics.

推进固态能量转换的核心挑战是发现能够解耦本质耦合热电参数的材料。虽然现有的层状离子材料,如六方Mg3Sb2,表现出结构的各向异性,但它们往往缺乏必要的定向输运,并且在不同的掺杂条件下性能不平衡。为了解决这一限制,我们引入了一个通用的设计原则,即阳离子稳定单层网络原则。该策略在概念上将晶体结构分离为可调谐的构建块,从而促进了具有定制各向异性的新相的合理工程。利用这一原理,我们计算发现了三种新的化合物类别:四方CICII2AV2三元化合物、四方cici3av2二元化合物和正交CICII2AV2三元化合物。对370种候选材料进行了系统的高通量筛选,确定了26种热力学稳定的材料。我们证实了这些相中电子和声子输运的强各向异性,例如CsMgBi(一种CICIIAV化合物)在ρκ = 3.5时的定向热导率表现出超高的各向异性。此外,四边形β-Mg3Sb2(一种CII3AV2化合物)作为一种优越的p型材料的鉴定,解决了目前普遍存在的六边形Mg3Sb2的显著性能缺陷。这项工作验证了带电单层稳定原理是合理发现新型、高各向异性和高性能离子层状热电材料的有力方法。

Natural anisotropic tissues, such as tendons and cartilages, achieve remarkable mechanical properties and various biofunctions through oriented hierarchical structures. Inspired from organisms, we develop a synergistic molecular and structural engineering technique based on the thermodynamically reversible reconfiguration of hydrogen bonds to achieve high-performance anisotropic supramolecular hydrogels by quenching pre-stretched polymer networks. Multiple inherent hydrogen bonds gradually dissociate under high-temperature processing to allow the good alignment of the polymer chains by uniaxial pre-stretching. The oriented polymer chains are then fixed on-site by rapid quenching-mediated hydrogen bond reconstruction at low temperatures (e.g., ice bath). This process merely relies on the inherent hydrogen bonds of polymer chains instead of traditional salting-out, metal ionic coordination and solvent effects. The optimal anisotropic hydrogel shows a tensile strength of 19.4 ± 0.7 MPa and toughness of 53.8 ± 5.2 MJ m-3 along the pre-stretching direction, which are 2.6- and 1.7-times higher than that of the unquenched isotropic hydrogels, respectively. This general strategy is applicable to different strong hydrogen bonding supramolecular hydrogel systems. Furthermore, we fabricate anisotropic hydrogel fibers as damping materials. This general approach for the preparation of anisotropic supramolecular hydrogels shows great potential for various engineering applications, such as in the fabrication protective and cushioning materials, flexible optoelectronics, and mechano-functional scaffolds.

天然各向异性组织,如肌腱和软骨,通过定向分层结构获得了显著的力学性能和各种生物功能。受生物体的启发,我们开发了一种基于氢键热力学可逆重构的协同分子和结构工程技术,通过淬火预拉伸聚合物网络来获得高性能的各向异性超分子水凝胶。多个固有氢键在高温处理下逐渐解离,通过单轴预拉伸使聚合物链良好排列。然后在低温(如冰浴)下通过快速淬火介导的氢键重建将定向聚合物链固定在现场。该工艺仅依靠聚合物链固有的氢键,而不是传统的盐析、金属离子配位和溶剂作用。最佳各向异性水凝胶沿预拉伸方向的抗拉强度为19.4±0.7 MPa,韧性为53.8±5.2 MJ -3,分别是未淬火各向异性水凝胶的2.6倍和1.7倍。这种一般策略适用于不同的强氢键超分子水凝胶体系。此外,我们还制备了各向异性水凝胶纤维作为阻尼材料。这种制备各向异性超分子水凝胶的一般方法在各种工程应用中显示出巨大的潜力,例如在制造保护和缓冲材料,柔性光电子和机械功能支架方面。

Due to their unique mixed ionic-electronic working mechanism and good biocompatibility, organic electrochemical transistors (OECTs) show great potential for applications in bioelectronics and neuromorphic electronics. Compared with the widely adopted floating gate setup, side gate OECTs, with well-defined device geometry and simpler fabrication and testing procedures, which may unleash the potential of OECTs for further integration and commercialization, are still under development. Here, the gate size (SG) and gate-channel distance (DGC) of side gates in vertical OECTs are precisely modulated by combining high-resolution printed silver gates and photo-patternable transistor channels. It is demonstrated that the performances of Homo-gDPP-based vOECTs show distinct variation when SG and DGC vary from 200 to 1600 µm2 and from 500 to 15 µm, respectively, for a channel area of only 30 × 30 µm2. Champion on current, peak transconductance, and on/off current ratio values of 13.83 ± 0.54 mA, 87.56 ± 2.76 mS, and (5.21 ± 0.27) × 108 are obtained with an SG of 1600 µm2 and a DGC of 15 µm, which are among the highest reported for side gate OECTs. Moreover, high-density complementary circuits are integrated in combination with the channel size and SG control, revealing the fastest switching speed (<9 ms) in reported side gate OECT circuits based on quasi-solid-state electrolytes (PEG-LiCl). This work provides a strategy for the optimal design and performance enhancement of OECTs and demonstrates ways for the miniaturization and integration of next-generation electronics based on OECTs.

有机电化学晶体管(OECTs)由于其独特的离子-电子混合工作机制和良好的生物相容性,在生物电子学和神经形态电子学领域显示出巨大的应用潜力。与广泛采用的浮动栅极结构相比,侧栅极OECTs仍处于开发阶段,具有明确的器件几何形状和更简单的制造和测试程序,可能释放出OECTs进一步集成和商业化的潜力。在这里,通过结合高分辨率印刷银门和光电图制化晶体管通道,精确调制垂直OECTs中侧门的栅极尺寸(SG)和栅极通道距离(DGC)。结果表明,当通道面积仅为30 × 30µm2时,SG和DGC分别在200 ~ 1600µm2和500 ~ 15µm范围内变化时,基于homo - gdpp的vOECTs的性能表现出明显的变化。在SG为1600µm2, DGC为15µm的情况下,获得了13.83±0.54 mA, 87.56±2.76 mS和(5.21±0.27)× 108的冠军电流,峰值跨导和通断电流比,这是报道的最高侧栅oect之一。此外,结合通道尺寸和SG控制集成了高密度互补电路,揭示了最快的开关速度(

Recurrent bacterial invasion delays the healing of infected sites; therefore, the development of a sustained antibacterial therapeutic strategy is essential. Herein, we use one simple multi-stage assembly strategy to develop a Lactobacillus reuteri-capsule patch that could achieve sustained antibacterial applications. The encapsulated strain retains its activity within the sodium alginate (SA) capsule, showing sustained release in response to pH changes in the infection microenvironment. In addition, the nanofiber structure of bacterial cellulose (BC) prevented contact between the strains and the lesion to avoid additional inflammatory reactions (the isolation rate reached 99.9%). The patch exhibited a sustained antibacterial effect against the formation of common pathogen biofilms by hindering biosynthesis (including E. coli, S. aureus, MRSA and P. aeruginosa), which avoided recurrent bacterial invasion. Transcriptomics results demonstrate that the patch exhibits various bioactivities to promote proliferation, migration and vascularization, in contrast with traditional antibiotic therapy. In vivo infection model verification further demonstrates that this patch effectively clears biofilms to prevent the recurrent invasion of P. aeruginosa, while achieving substantial tissue regeneration through collagen deposition and neovascularization. This strategy provides a simple and efficient approach for persistent anti-infection application.

反复的细菌侵袭会延迟感染部位的愈合;因此,开发一种持续的抗菌治疗策略至关重要。在这里,我们使用一个简单的多阶段组装策略来开发一个罗伊氏乳杆菌胶囊贴片,可以实现持续的抗菌应用。被封装的菌株在海藻酸钠(SA)胶囊内保持活性,在感染微环境的pH变化下表现出持续释放。此外,细菌纤维素(BC)的纳米纤维结构阻止了菌株与病变之间的接触,避免了额外的炎症反应(分离率达到99.9%)。该贴片通过抑制常见病原菌生物合成(包括大肠杆菌、金黄色葡萄球菌、MRSA和铜绿假单胞菌),对常见病原菌生物膜的形成具有持续的抗菌作用,避免了细菌的反复侵袭。转录组学结果表明,与传统的抗生素治疗相比,该贴片具有促进增殖、迁移和血管形成的多种生物活性。体内感染模型验证进一步表明,该贴片有效清除生物膜,防止铜绿假单胞菌的复发侵袭,同时通过胶原沉积和新生血管实现实质性的组织再生。该策略为持久的抗感染应用提供了一种简单有效的方法。

Materials with strong negative thermal expansion (NTE) are crucial for both fundamental research and thermal expansion control engineering. Our previous studies have shown that significantly enhanced NTE can be achieved in PbTiO3-BiFeO3 and PbTiO3-BiCoO3 ferroelectrics by improving the tetragonal distortion (c/a) of the parent PbTiO3. However, the detailed microscopic mechanisms behind this intriguing phenomenon remain unclear. In this study, we explored the temperature-dependent chemical bonding characteristics using high-energy synchrotron X-ray powder diffraction combined with Rietveld refinement, the maximum entropy method, and first-principles calculations. The temperature evolution of the electron density distribution in the ferroelectric phase of 0.5PbTiO3-0.5BiFeO3 and 0.6PbTiO3-0.4BiCoO3 provides direct evidence of strong covalency, not only in the A-site Pb/Bi-O2 bonds but also in the B-site Ti/Fe/Co-O1 bonds. This covalent character promotes spontaneous polarization through displacements of the highly polarizable A- and B-site cations. Our results reveal that the distinct covalent nature of the Fe-O and Co-O bonds results in contrasting temperature-dependent unit cell volume behaviors, with PbTiO3-BiFeO3 exhibiting strong nonlinear NTE and PbTiO3-BiCoO3 displaying colossal volume contraction. These findings elucidate the microscopic origin of the NTE in PbTiO3-based ferroelectrics and pave the way for the design of new materials with enhanced NTE properties.

具有强负热膨胀特性的材料在基础研究和热膨胀控制工程中具有重要意义。我们之前的研究表明,通过改善母体PbTiO3的四方畸变(c/a),可以显著增强PbTiO3- bifeo3和PbTiO3- bicoo3铁电体的NTE。然而,这一有趣现象背后的详细微观机制仍不清楚。在这项研究中,我们利用高能同步加速器x射线粉末衍射,结合Rietveld细化,最大熵法和第一性原理计算,探索了温度依赖的化学键特征。0.5PbTiO3-0.5BiFeO3和0.6PbTiO3-0.4BiCoO3的铁电相电子密度分布的温度演化提供了强共价的直接证据,不仅在a位Pb/Bi-O2键中,而且在b位Ti/Fe/Co-O1键中。这种共价特性通过高度极化的A和b位阳离子的位移促进自发极化。我们的研究结果表明,Fe-O和Co-O键的不同共价性质导致了不同温度依赖的单元胞体积行为,PbTiO3-BiFeO3表现出强烈的非线性NTE,而PbTiO3-BiCoO3表现出巨大的体积收缩。这些发现阐明了pbtio3基铁电体中NTE的微观来源,并为设计具有增强NTE性能的新材料铺平了道路。

Advancements in wearable human-machine interfaces require haptic systems that are mechanically compliant, functionally versatile, and capable of delivering rich tactile and proprioceptive feedback under varying interaction conditions. However, existing haptic devices are often constrained by bulky structures, rigid components, insufficient actuation modalities, and the absence of self-sensing capabilities, which restrict their wearability, responsiveness, robustness, and seamless integration with the human body. This work presents multimodal, self-sensing, haptic interfaces enabled by programmable soft magnetic composites and phase change materials, which provide three distinct working modes (normal, rotational shear, and skin stretch) within a compact, skin-conformal form factor. The haptic interface leverages soft magnets with programmable magnetization profiles to enable multimodal actuation. Hybrid electromagnetic coils, incorporating both solenoid and planar configurations fabricated with stretchable gallium-based conductors, are designed to enhance stretchability and actuation output. Combined with a Kirigami-patterned elastomeric spring, the haptic actuator generates forces and displacements that exceed human tactile perception thresholds while maintaining performance under deformation. Furthermore, the inductance-based self-sensing mechanism provides real-time displacement monitoring for closed-loop control, ensuring consistent performance across varying actuation and interaction conditions.

可穿戴人机界面的进步要求触觉系统具有机械适应性、功能通用性,并且能够在不同的交互条件下提供丰富的触觉和本体感觉反馈。然而,现有的触觉设备往往受到笨重的结构、刚性组件、不充分的驱动模式和缺乏自我传感能力的限制,这限制了它们的可穿戴性、响应性、稳健性和与人体的无缝集成。这项工作提出了由可编程软磁复合材料和相变材料实现的多模态、自传感、触觉界面,在紧凑的皮肤保形形状因子内提供三种不同的工作模式(正常、旋转剪切和皮肤拉伸)。触觉界面利用具有可编程磁化配置文件的软磁铁来实现多模态驱动。混合电磁线圈结合了电磁线圈和平面结构,由可拉伸的镓基导体制成,旨在提高可拉伸性和驱动输出。结合kirigami图案的弹性弹簧,触觉致动器产生的力和位移超过了人类的触觉感知阈值,同时在变形下保持性能。此外,基于电感的自传感机制为闭环控制提供实时位移监测,确保在不同的驱动和交互条件下保持一致的性能。最终,我们的软多模态触觉装置可以促进多种皮肤机械感受器的选择性刺激,并已被证明可以准确地编码肢体空间位置和关节运动,以获得全面的本体感觉反馈。

Conventional Miura Origami (Miura-Ori) metamaterials, despite their geometric elegance and tunable folding behavior, are inherently constrained in energy absorption performance due to their rigid periodicity and structural uniformity. In this work, we disrupt these limitations by introducing strategically engineered geometric disorder into Miura-Ori-based sandwich structures, resulting in dramatic enhancements in both mechanical robustness and energy dissipation. Among the tested designs, the best-performing disordered structures exhibit a 194.98% increase in elastic modulus, 105.22% enhancement in specific energy absorption, and 118.03% rise in mean compressive force compared to their uniform counterparts. Driven by these breakthroughs, we develop a powerful computational inverse design algorithm that autonomously generates geometric configurations to precisely match target force-displacement profiles. This algorithm unlocks a vastly expanded design space, enabling the creation of highly customizable and high-performance disordered metamaterials. Rigorous simulations and experimental validations corroborate the superior capabilities of our approach. As a compelling application, we design a Miura-Ori-inspired fuselage tube, where geometric disorder effectively suppresses peak impact forces during crash events. This study redefines the role of disorder-transforming it from a structural limitation into a functional asset-and establishes a foundational paradigm for the data-driven design of next-generation energy-absorbing metamaterials.

传统的三浦折纸(Miura- ori)超材料,尽管具有几何优雅和可调的折叠行为,但由于其刚性周期性和结构均匀性,在能量吸收性能上受到固有的限制。在这项工作中,我们通过在基于miura - ori的三明治结构中引入战略性工程几何无序来打破这些限制,从而大大增强了机械稳健性和能量耗散。试验结果表明,与均匀结构相比,无序结构弹性模量提高194.98%,比能吸收提高105.22%,平均压缩力提高118.03%。在这些突破的推动下,我们开发了一种强大的计算反设计算法,可以自主生成几何构型,以精确匹配目标力-位移剖面。该算法解锁了一个极大扩展的设计空间,使创建高度可定制和高性能的无序超材料成为可能。严格的模拟和实验验证证实了我们的方法的优越性能。作为一个引人注目的应用,我们设计了一个受三浦-奥里启发的机身管,其中几何无序有效地抑制了碰撞事件中的峰值冲击力。本研究重新定义了无序的作用,将其从结构限制转变为功能资产,并为下一代吸能超材料的数据驱动设计建立了基础范例。

Daytime sub-ambient radiative cooling offers a passive means of reducing surface temperatures below ambient levels under direct sunlight. Existing hybrid systems that combine radiative and evaporative cooling rely exclusively on broadband radiative coolers, which are effective only for sky-facing horizontal surfaces. However, their performance deteriorates sharply in vertical orientations, such as building façades and vehicle exteriors, where angular limitations and environmental heat gains significantly diminish cooling efficiency. Here, we present a robust approach that achieves persistent sub-ambient daytime cooling on vertical surfaces by integrating a spectrally selective thermal emitter with a self-hygroscopic hydrogel. The selective emitter minimizes radiative heat influx from the ground and surroundings while protecting the hydrogel, which absorbs atmospheric moisture at night and drives evaporative cooling during the day. Under direct solar irradiation of 900 W m-2, our system achieves temperature reductions of up to 6.1 °C below ambient temperatures. This durable and orientation-tolerant cooling strategy provides a practical pathway to extend passive cooling technologies from horizontal to vertical and other non-traditional surfaces.

白天的亚环境辐射冷却提供了一种在阳光直射下将地表温度降低到环境温度以下的被动方法。现有的结合辐射和蒸发冷却的混合系统完全依赖于宽带辐射冷却器,这种冷却器仅对面向天空的水平表面有效。然而,它们的性能在垂直方向上急剧恶化,例如建筑立面和车辆外墙,在这些地方,角度限制和环境热量的增加大大降低了冷却效率。在这里,我们提出了一种强大的方法,通过集成光谱选择性热发射器和自吸湿水凝胶,在垂直表面上实现持续的亚环境白天冷却。选择性发射器最大限度地减少来自地面和周围环境的辐射热流入,同时保护水凝胶,水凝胶在夜间吸收大气水分,白天驱动蒸发冷却。在900 W m-2的太阳直接照射下,我们的系统实现了比环境温度低6.1°C的温度降低。这种耐用且可定向的冷却策略为将被动冷却技术从水平表面扩展到垂直表面和其他非传统表面提供了切实可行的途径。

Seawater splitting has emerged as a promising alternative to overall water splitting because it eliminates the kinetically sluggish oxygen evolution reaction (OER), which is a bottleneck in water splitting, and avoids the low economic value of O2. Moreover, in seawater splitting, H2 evolution coupled with the oxidation of chloride (Cl-) to value-added chlorine (Cl2) and/or hypochlorous acid (HOCl) can simultaneously benefit the energy and environmental sectors. Cl2 and HOCl are widely used for bleaching, disinfection, sanitisation and sterilisation in the medical sector and for purifying drinking water and water in swimming pools owing to their strong oxidising and antibacterial properties. Mainstream industrial production employs the chlor-alkali electrolysis of sodium chloride (NaCl), which requires significant energy input and releases enormous amounts of CO2. To achieve the sustainable production of Cl2 and HOCl while reducing energy consumption and environmental impacts, photocatalytic (PC) and photoelectrochemical (PEC) technologies have been employed as green alternatives. Importantly, PC and PEC enable the on-site production of Cl2/HOCl in remote areas, which can circumvent their instability (decomposition), storage and transport issues. This article reviews the recent progress in the PC and PEC production of Cl2/HOCl, along with the catalytic materials used and their designs and photocatalytic performance. The applications of in situ HOCl production in anti-bacterial treatment, ammonia removal, the selective oxidation and conversion of organic compounds, and CO2 conversion are discussed. We also address the challenges in this area and highlight prospects for future research directions. Overall, we demonstrate that the PC and PEC production of Cl2/HOCl serves as a green and sustainable alternative to the chlor-alkali process. This research area is still in its infancy, and we hope that this review article will garner the attention of researchers to contribute to this area, leading to a step closer toward practical applications.

海水裂解由于消除了析氧反应(OER)这一分解水的瓶颈,避免了O2经济价值低的问题,成为替代整体水裂解的一种很有前景的方法。此外,在海水分解过程中,H2的演化与氯(Cl-)氧化生成增值氯(Cl2)和/或次氯酸(HOCl)同时有益于能源和环境部门。二氧化氯和高氯酸盐由于具有很强的氧化和抗菌性能,被广泛用于医疗部门的漂白、消毒、消毒和灭菌,以及净化饮用水和游泳池的水。主流工业生产采用氯碱电解氯化钠(NaCl),这需要大量的能量输入,并释放大量的二氧化碳。为了实现Cl2和HOCl的可持续生产,同时减少能源消耗和环境影响,光催化(PC)和光电化学(PEC)技术已被用作绿色替代技术。重要的是,PC和PEC能够在偏远地区现场生产Cl2/HOCl,这可以避免它们的不稳定性(分解)、储存和运输问题。本文综述了Cl2/HOCl的PC和PEC生产的最新进展,以及所使用的催化材料、设计和光催化性能。讨论了原位生产HOCl在抗菌处理、除氨、有机物选择性氧化转化、CO2转化等方面的应用。本文还讨论了该领域面临的挑战,并对未来的研究方向进行了展望。总的来说,我们证明了Cl2/HOCl的PC和PEC生产是一种绿色和可持续的氯碱工艺替代方案。这一研究领域还处于起步阶段,我们希望这篇综述文章能引起研究人员的关注,为这一领域做出贡献,使其向实际应用更近一步。
