Nonvolatile memories based on low-dimensional materials are pivotal for miniaturized data storage but face challenges in endurance and charge retention. We report a mixed-dimensional memory architecture integrating monolayer MoS₂ with CdSe@CdS core-shell quantum dots (QDs) to address these limitations. By synthesizing polyhedral QDs with facet-engineered surfaces and electrochemically inert passivating ligands, interfacial defects are substantially minimized, enabling efficient charge confinement within CdSe cores via Fowler-Nordheim tunneling. The optimized heterostructure device demonstrates a memory window of 140 V, an on/off ratio of 10⁶, endurance exceeding 5 × 10⁴ cycles, and 96.5% charge retention over 10 years—outperforming previously reported QD-based memories. Furthermore, the cascaded charge transfer mechanism (MoS₂→CdS→CdSe), corroborated by electrical measurements, highlights the critical role of synergistic structural and surface optimization in suppressing charge leakage. This work establishes a scalable platform combining 2D semiconductors and defect-engineered QDs, offering insights into charge dynamics and advancing the development of high-performance, nanoscale nonvolatile memories.

基于低维材料的非易失性存储器是小型化数据存储的关键，但在耐用性和电荷保持方面面临挑战。我们报告了一种将单层MoS2与CdSe@CdS核壳量子点（QDs）集成在一起的混合维存储架构，以解决这些限制。通过合成具有面工程表面和电化学惰性钝化配体的多面体量子点，可以大大减少界面缺陷，从而通过Fowler-Nordheim隧道在CdSe核心内实现有效的电荷约束。优化后的异质结构器件的记忆窗口为140 V，开关比为106，续航时间超过5 × 104次，超过10年的电荷保留率为96.5%，优于先前报道的基于量子点的存储器。此外，电测量证实了级联电荷转移机制（MoS2→CdS→CdSe），强调了协同结构和表面优化在抑制电荷泄漏中的关键作用。这项工作建立了一个结合二维半导体和缺陷工程量子点的可扩展平台，提供了对电荷动力学的见解，并推进了高性能、纳米级非易失性存储器的发展。

Microscale biohybrid robots harnessing naturally motile cells offer autonomous long-lasting propulsion and biocompatibility. Yet, precisely directing and controlling their motion remains challenging. Here we demonstrate independent and simultaneous control over different types of biohybrid microrobots and complex motion pattern generation by combining multiple inputs into a single microrobot. We present a novel motion control mechanism for simultaneous phototactic and magnetotactic operation of biohybrid microrobots based on wild-type and blind Chlamydomonas reinhardtii (CR) modified with gelatin-Fe₃O₄ nanoparticles (gel-SPION). As a result, we developed methods to precisely control the motion of three distinct biohybrids with combined light and magnetic fields. By applying a combination of light and magnetic fields, different biohybrid strains can be sorted in different directions and controlled independently by decoupling the biohybrid magnetotactic and phototactic responses. This work lays the foundation for programmable, selective manipulation of biohybrid microrobots in variable environments, paving the way for advanced control strategies.

微型生物混合机器人利用自然运动细胞提供自主持久推进和生物相容性。然而，精确地指导和控制它们的运动仍然是一个挑战。在这里，我们展示了对不同类型的生物混合微型机器人的独立和同时控制，以及通过将多个输入组合到一个微型机器人中来生成复杂的运动模式。基于明胶- fe3o4纳米粒子修饰的野生型和盲型莱茵衣藻（CR）（gel-SPION），提出了一种同时进行趋光和趋磁操作的生物混合微型机器人运动控制机制。因此，我们开发了一种方法，通过结合光和磁场来精确控制三种不同的生物杂交体的运动。在光、磁场联合作用下，通过解耦生物杂交种的趋磁和趋光响应，可以实现不同生物杂交种在不同方向上的分选和独立控制。这项工作为可变环境下生物混合微型机器人的可编程、选择性操作奠定了基础，为先进的控制策略铺平了道路。

Atmospheric moisture sorbents (AMSs) possess ideal structures that enable spontaneous absorption of substantial amounts of moisture from ambient environment. This passive adsorption process requires no additional energy input and is considered as a clean technology for sustainability. Characterized by their environmental friendliness, versatility, and scalability, AMSs have enabled sustainable applications across the agriculture, food, environment, and energy nexus. In this review, the interaction mechanism between AMSs and moisture is systematically revealed from multiple perspectives. Then we comprehensively assess AMSs-enabled sustainability across agricultural productivity, food security, environmental resilience, and energy transition. In order to meet sustainability objectives, particular emphasis is placed on evaluating the efficiency, feasibility, and cost-effectiveness of practical applications based on comprehensive analysis of material compositions, structural characteristics, and performance metrics. In the future, AMSs are expected to play a pivotal role in addressing critical challenges in agriculture, food, environment, and energy systems, particularly in resource-constrained regions, while contributing to the global strategic goals of energy conservation and carbon neutrality.

大气吸湿剂（ams）具有理想的结构，能够从周围环境中自发吸收大量的水分。这种被动吸附过程不需要额外的能量输入，被认为是一种可持续的清洁技术。ams的特点是环境友好、多功能性和可扩展性，使农业、食品、环境和能源领域的可持续应用成为可能。本文从多个角度系统地揭示了ams与水分的相互作用机制。然后，我们全面评估了农业生产力、粮食安全、环境恢复力和能源转型等领域的ams可持续性。为了满足可持续发展的目标，特别强调在材料成分、结构特征和性能指标的综合分析的基础上评估实际应用的效率、可行性和成本效益。未来，预计自动农业系统将在应对农业、粮食、环境和能源系统的重大挑战方面发挥关键作用，特别是在资源受限地区，同时为实现节能和碳中和的全球战略目标作出贡献。

Sodium-metal anodes hold great promise for high-energy-density sodium-based batteries, yet their application is hindered by poor cycling stability and safety concerns arising from interfacial instability and uncontrolled dendritic growth. Herein, we propose a multifunctional sodium-metal composite anode based on 3D porous carbon framework embedded with molybdenum nitride (MoN) nanoparticles. During sodiation, MoN undergoes in situ conversion to metallic Mo and Na₃N while catalyzing NaPF₆ decomposition to form NaF, leading to a self-evolved fluoronitrided interphase (Na₃N/NaF). This robust SEI combines mechanical resilience, high surface energy, and superior Na⁺ conductivity, ensuring uniform deposition and dendrite suppression. Consequently, the symmetric cell achieves low overpotential and exceptional cycling stability over 2,000 h at 3 mA cm⁻². When paired with a Na₃V₂(PO₄)₃ cathode, the full-battery presents remarkable electrochemical performance with an energy density of 265 Wh kg⁻¹. This strategy stabilizes sodium-metal interfaces and paves a promising route toward high-performance and durable sodium-metal batteries for sustainable energy storage.

钠金属阳极在高能量密度钠基电池中具有很大的应用前景，但由于界面不稳定和不受控制的枝晶生长引起的循环稳定性差和安全性问题，阻碍了它们的应用。在此，我们提出了一种基于嵌入氮化钼纳米粒子的三维多孔碳框架的多功能钠-金属复合阳极。在钠化过程中，MoN在原位转化为金属Mo和Na3N，同时催化NaPF6分解形成NaF，导致自进化的氟氮化界面（Na3N/NaF）。这种坚固的SEI结合了机械弹性、高表面能和优异的Na+导电性，确保了均匀的沉积和枝晶抑制。因此，对称电池在3ma cm - 2下实现了低过电位和超过2000小时的卓越循环稳定性。当与Na3V2(PO4)3阴极配对时，该电池的能量密度达到265 Wh kg−1，具有良好的电化学性能。这一策略稳定了钠-金属界面，为高性能和耐用的钠-金属电池的可持续能量存储铺平了一条有希望的道路。

Structural colors in living creatures often feature diverse gradient color patterns composed of (sub)micron-sized pixels, leading to dynamic and complex visual signals. However, conventional single-material printing of artificial structural colors yields only one color at a time, limiting spatial resolution and tunability. Here, we report a combinatorial aerosol printing (CAP) strategy, a multi-ink variant of aerosol jet printing, to produce pixelated mechanochromic cholesteric liquid crystal elastomers (CLCEs) with ≈15 μm line resolution and 1.1 μm thickness. By co-delivering and mixing aerosolized inks in situ, CAP enables continuous compositional gradients within individual pixels, yielding high-saturation colors with tunable helical pitch and Young’s modulus. Further, CLCE patterns can be directly printed on curved substrates, surpassing constraints of traditional methods. The ability to tailor optical and mechanical properties at high resolution establishes a versatile platform for mechanochromic materials, with applications in responsive displays, QR coding, biomimetic camouflage, and wearable photonic sensors.

As a key component of rechargeable batteries, electrode materials significantly influence their electrochemical performance. However, existing electrode materials fail to meet the growing demands of practical applications, posing a major obstacle to advancing rechargeable battery technology. In recent years, high-entropy materials (HEMs) with unique structural characteristics have been considered as promising candidates for enhancing the electrochemical performance of rechargeable batteries. In this review, we systematically discuss the preparation methods, characterization technologies, electrochemical properties, and energy storage mechanisms of HEMs. In addition, we summarize the research progress of HEMs for application in rechargeable batteries, including alloys, oxides, sulfides, selenides, phosphates, Prussian blue analogs, and MXene. More importantly, we deeply analyze the relationship between the properties of HEMs and their potential applications in rechargeable batteries, as well as the remaining challenges of HEMs. This work provides strategic insights to accelerate the discovery of next-generation electrode materials for rechargeable batteries.

电极材料作为可充电电池的关键部件，对电池的电化学性能有着重要的影响。然而，现有的电极材料不能满足日益增长的实际应用需求，这是推动可充电电池技术发展的主要障碍。近年来，具有独特结构特性的高熵材料被认为是提高可充电电池电化学性能的有希望的候选材料。本文系统地介绍了HEMs的制备方法、表征技术、电化学性能和储能机理。此外，我们还总结了HEMs在可充电电池中的研究进展，包括合金、氧化物、硫化物、硒化物、磷酸盐、普鲁士蓝类似物和MXene等。更重要的是，我们深入分析了HEMs的性能与其在可充电电池中的潜在应用之间的关系，以及HEMs仍面临的挑战。这项工作为加速发现下一代可充电电池电极材料提供了战略见解。
