The development of high-performance transparent conductors (TCs) is critical for advancing transparent electronics and optoelectronic devices. While n-type TCs are well established, the development of p-type TCs remains hindered by the limited availability of suitable materials. In this study, the layered double perovskite Cs₄ZnBi₂Cl₁₂ was synthesized as a promising p-type TC, which exhibits a wide direct band gap of 3.56 eV and intrinsic p-type conductivity. A hydration-mediated strategy was developed to trigger a near-spherical nanocrystal-to-nanorod transformation and modulate the electronic structure. First-principles calculations clarify that the lattice compressive strain induced by hydration significantly reduces the hole effective mass while increasing conductivity from 8.99 to 9.21 mS cm⁻¹, outperforming traditional p-type TCs, such as CuAlO₂ (3.4 mS cm⁻¹) and SrCu₂O₂ (0.48 mS cm⁻¹). These findings not only provide experimental validation of the theoretical predictions regarding Cs₄ZnBi₂Cl₁₂ as a p-type TC but also establish a hydration strategy for optimizing the optical and electrical performance of layered double perovskites.

高性能透明导体（TCs）的发展对于推进透明电子和光电子器件的发展至关重要。虽然n型碳纳米管已经很成熟，但p型碳纳米管的发展仍然受到合适材料供应有限的阻碍。在本研究中，合成了层状双钙钛矿Cs4ZnBi2Cl12作为有前途的p型TC，它具有3.56 eV的宽直接带隙和固有的p型电导率。开发了一种水化介导策略来触发近球形纳米晶体到纳米棒的转变并调节电子结构。第一性原理计算表明，水化引起的晶格压缩应变显著降低了空穴的有效质量，同时将电导率从8.99 mS cm−1提高到9.21 mS cm−1，优于传统的p型tc，如CuAlO2 （3.4 mS cm−1）和SrCu2O2 （0.48 mS cm−1）。这些发现不仅为Cs4ZnBi2Cl12作为p型TC的理论预测提供了实验验证，而且为优化层状双钙钛矿的光学和电学性能建立了水化策略。

Proteins serve as bioactive components and primary building blocks of hydrogels for bioengineering. While extracellular matrices and blood derivatives from animals and humans have been widely explored, the use of in vitro-cultured cells as bioactive sources remains limited. The cell secretome holds therapeutic potential administered in its liquid form and has been previously incorporated within exogenous materials that confer structural features to secretome-enriched devices. Producing hydrogels exclusively from cell-secreted sources could enhance the predictability, potency, and autologous character of these technologies. Here, we suggest the processing of secretomes derived from adipose-tissue-derived mesenchymal stromal cells (MSCs) and their further crosslinking into volumetric structures. Secretomes from pristine and interferon-γ (IFN-γ)-primed MSCs showed different protein compositions, with high reproducibility between production cycles, generalized high cytocompatibility, and pro-angiogenic activity. The platform introduced herein may be used to explore secretomes of different cell types, targeting applications that may benefit from their therapeutic and biotechnological potential.

All-inorganic CsPbX₃ perovskite quantum dots (PeQDs) offer exceptional optical properties, yet producing bright, stable, pure-blue CsPbBr₃ light-emitting diodes (PeLEDs) remains challenging due to a lack of reliable methods to precisely control the size of PeQDs and induce strong quantum confinement. Here, we report a spatial-confinement approach using metal-organic frameworks to synthesize monodisperse CsPbBr₃ QDs as small as 1.9 nm. Subsequent surface engineering via 3,3-diphenylpropylamine ligand exchange and ionic liquid treated hole transport layers yields pure-blue PeLEDs with a luminance of 2,037 cd m⁻² and an external quantum efficiency of 5.04% at 460 nm. Additionally, we introduce a scalable and solution-processable stamp-mask patterning technique for in situ fabrication of large-scale patterned pure-blue PeLEDs in the emission layer while preserving QD crystallization, nucleation, and film integrity. This simple, rapid, and effective strategy offers valuable reference for the controlled synthesis of ultrasmall PeQDs and the advancement of patterned optoelectronic devices.

全无机CsPbX3钙钛矿量子点（PeQDs）具有优异的光学性能，但由于缺乏精确控制PeQDs尺寸和诱导强量子约束的可靠方法，生产明亮、稳定的纯蓝色CsPbBr3发光二极管（pled）仍然具有挑战性。在这里，我们报道了一种使用金属有机框架的空间约束方法来合成小至1.9 nm的单分散CsPbBr3量子点。随后通过3,3-二苯基丙胺配体交换和离子液体处理的空穴传输层进行表面工程，得到亮度为2037 cd m−2的纯蓝色pled，在460 nm处的外量子效率为5.04%。此外，我们还介绍了一种可扩展和溶液可加工的印章掩模图图化技术，用于在发射层中原位制造大规模图图化纯蓝色pled，同时保持QD结晶，成核和薄膜完整性。这一简单、快速、有效的方法为超小型peqd的受控合成和图像化光电器件的发展提供了有价值的参考。

We demonstrate that a single DNA duplex that is designed to allow binding to specific metal ions (Hg²⁺/Ag⁺) and <3 nm in length can function as a fully electronic multi-bit memory system (+1, 0, −1). The system is reversible, allowing digital information to be electrically written, read, and erased in a solid-state, chip-based platform. This demonstrates a method that can enable DNA-based systems to be integrated with conventional electronics at scale and to electrically control chemical reactions that allow the electronic structure within the DNA to be modified to store information.

我们证明，单个DNA双工被设计成允许与特定金属离子（Hg2+/Ag+）结合，并且长度为<； 3nm，可以作为一个全电子多比特存储系统（+ 1,0,−1）。该系统是可逆的，允许在固态芯片平台上对数字信息进行电写入、读取和擦除。这证明了一种方法，可以使基于DNA的系统与传统电子学大规模集成，并通过电气控制化学反应，从而修改DNA内的电子结构以存储信息。

Since the discovery of the underwater superoleophobic phenomenon in fish scales, natural archetypes have continuously driven the advancement of underwater superoleophobic materials (USMs). Despite notable progress, achieving robust performance in complex real-world applications remains a challenge. In this review, we systematically trace the evolution of bioinspired USMs (BUSMs) from bioinspired design to practical demands. First, the evolution of bioinspired design and related foundational theories is reviewed. Then, we outline key design principles spanning non-responsiveness to stimuli-responsive interfaces and evaluate their performance against practical demands, including mechanical stability, environmental tolerance, and recovery capacity. Furthermore, we highlight emerging applications, such as oil droplet manipulation, anti-oil fouling, and oil/water separation. Finally, we discuss the critical challenges and opportunities of advanced BUSMs that are proposed to address emerging demands in their development.

自发现鱼鳞的水下超疏油现象以来，自然原型不断推动着水下超疏油材料（USMs）的发展。尽管取得了显著进展，但在复杂的实际应用程序中实现健壮的性能仍然是一个挑战。在这篇综述中，我们系统地追溯了生物启发usm （busm）从生物启发设计到实际需求的演变。首先，回顾了仿生设计的发展历程和相关的基础理论。然后，我们概述了从非响应性到刺激响应性界面的关键设计原则，并根据实际需求评估了它们的性能，包括机械稳定性、环境耐受性和恢复能力。此外，我们重点介绍了新兴应用，如油滴操纵，防油结垢和油水分离。最后，我们讨论了先进商业智能管理系统的关键挑战和机遇，这些挑战和机遇是为了解决其发展中出现的新需求而提出的。

Halogen-based batteries (HBBs) exhibit promising potential for advanced energy storage demands due to their superior theoretical capacities and substantial raw material abundance. However, the inherent limitations associated with halogen chemistry severely impede the practical application of HBB technology. Host material engineering has emerged as an effective solution to address problems, including slow charge-transfer kinetics, unstable halogen redox, and undesired active species shuttling in HBBs. This review systematically delineates recent progress in host material development for advanced HBBs. Initially, the theoretical framework of HBBs is established by tracing evolutionary history, delineating battery configurations, and clarifying the fundamental halogen-based energy storage principles. Subsequently, the challenges associated with halogen conversion chemistry, the essential criteria for host materials, and current host design patterns are outlined. Finally, this review identifies the persistent challenges in current host applications and proposes strategic future research directions for developing high-performance next-generation HBBs.

Metal-organic framework (MOF) thin films offer exceptional properties for diverse applications, yet the mechanisms underlying MOF crystallization are not fully understood. Knowledge gaps remain regarding the nucleation and growth mechanisms of these highly porous, crystalline materials under dynamic evaporative conditions. Here, an in situ grazing incidence wide-angle X-ray scattering (GIWAXS) combined with a microkinetic model is used to probe the dynamic growth of MOF films. We show that while most high-order oligomers are produced in the solution phase, the key parameters that control thin-film growth are autocatalytic synthesis of secondary building units (SBUs) followed by physisorption on silicon wafer substrate, exponential growth due to evaporation-driven step growth, and transition to the stationary phase due to mass-transfer-limited growth. Importantly, this study demonstrates the applicability of this microkinetic modeling framework to predict film properties across a range of temperatures and reactant concentrations, allowing for rational design of MOF thin films.

金属有机框架（MOF）薄膜为各种应用提供了卓越的性能，但MOF结晶的机制尚不完全清楚。关于这些高多孔晶体材料在动态蒸发条件下的成核和生长机制的知识差距仍然存在。本文采用原位掠入射广角x射线散射（GIWAXS）技术结合微动力学模型来研究MOF薄膜的动态生长。我们发现，虽然大多数高阶低聚物是在溶液阶段产生的，但控制薄膜生长的关键参数是二级构建单元（SBUs）的自催化合成，随后在硅片衬底上物理吸附，蒸发驱动的阶梯生长导致的指数增长，以及由于传质限制生长而过渡到固定相。重要的是，这项研究证明了这种微动力学建模框架在不同温度和反应物浓度下预测薄膜性能的适用性，从而允许合理设计MOF薄膜。

Although dimeric acceptors have demonstrated promising efficacy for improving operational stability of organic solar cells (OSCs), the power conversion efficiencies (PCEs) of corresponding binary devices remain constrained due to their weak intermolecular interactions and undesirable molecular packing. Here, we integrate a dimerization with asymmetric terminal strategy to design a heterodimer acceptor, NVB. Breaking molecular symmetry enhances dipole interactions and optimizes molecular packing, leading to superior charge transport and suppressed recombination. As a result, the PM6:NVB-based device achieves a record-high efficiency of 19.90% (certified as 19.35%), representing the highest value reported for all dimer-based binary devices thus far. Remarkably, the NVB-based device exhibits enhanced stability with a T₈₀ (lifetime for maintaining 80% of its initial efficiency) over 1,500 h, attributed to elevated glass transition temperature (T_g). Overall, this work establishes an “asymmetric dimerization” paradigm that concurrently improves efficiency and stability through molecular engineering, providing a practical pathway toward high-performance OSCs.

尽管二聚体受体在提高有机太阳能电池（OSCs）的运行稳定性方面表现出了良好的效果，但由于其分子间相互作用弱和不良的分子堆积，相应的二元器件的功率转换效率（pce）仍然受到限制。在这里，我们将二聚化与不对称末端策略相结合，设计了一个异二聚体受体NVB。打破分子对称增强偶极相互作用和优化分子堆积，导致优越的电荷传输和抑制重组。因此，基于PM6: nvb的器件实现了19.90%（认证为19.35%）的创纪录高效率，代表了迄今为止所有基于二聚体的二进制器件所报告的最高值。值得注意的是，由于玻璃化转变温度（Tg）升高，基于nvb的器件表现出更高的稳定性，T80（保持80%初始效率的寿命）超过1500小时。总的来说，这项工作建立了一种“不对称二聚化”模式，通过分子工程同时提高了效率和稳定性，为高性能osc提供了一条实用的途径。

Ultra-high dynamic strength and toughness are crucial for fibrous materials in impact-protective applications. However, the trade-off between strength and toughness is a persistent challenge in materials science. Herein, by regulating the orientation of long carbon nanotubes within fibers, we fabricated carbon nanotube/heterocyclic aramid composite fibers with a dynamic strength of 10.3 GPa and a dynamic toughness of 706.1 MJ m⁻³. The ultra-high dynamic performance is attributed to the inhibited slippage and thus remarkable breakage of polymer chains during the high-strain-rate loading process; these behaviors are due to the improved alignment of polymer chains, reduced porosity, and thus enhanced interfacial interactions and load transfer efficiency therein induced by aligned long carbon nanotubes and multi-stage drafting. This work provides a fresh understanding and a feasible route for utilizing the intrinsic mechanical performance of polymer chains at the macroscale.

在冲击防护应用中，纤维材料具有超高的动态强度和韧性。然而，强度和韧性之间的权衡是材料科学中一个持久的挑战。通过调节长碳纳米管在纤维中的取向，我们制备了碳纳米管/杂环芳纶复合纤维，其动态强度为10.3 GPa，动态韧性为706.1 MJ m−3。超高的动态性能是由于在高应变率加载过程中抑制了聚合物链的滑移和明显的断裂；这些行为是由于排列的长碳纳米管和多阶段拉伸导致聚合物链的排列改善，孔隙率降低，从而增强了界面相互作用和负载传递效率。这项工作为在宏观尺度上利用聚合物链的内在力学性能提供了新的认识和可行的途径。
