Passive radiative cooling (PRC) textiles offer a sustainable route for personal thermoregulation, yet their performance is often compromised under high humidity or intense perspiration. Here, we present a synergistic radiative-evaporative cooling and sweat-sensing textile (RECS textile) that unifies efficient thermal regulation and high-fidelity sweat monitoring for personal hygrothermal regulation. The textile consists of two asymmetrically functionalized bilayers, the SiO2- and K2Ti6O13-modified Janus nonwovens printed with flexible liquid-metal electrodes, collectively forming a Janus structure with asymmetric porosity and wettability. This design enables unidirectional sweat transport across the textile thickness, simultaneously sustaining evaporative cooling, enhancing radiative spectral selectivity through cooperative Mie scattering, solar reflection, and mid-infrared emission, and continuously delivering sweat to the sensing electrode without accumulation or dilution. Consequently, the synergistic radiative-evaporative mechanism contributes a cooling effect of 19.9°C (12.0°C contributed by evaporative cooling) under hygrothermal environments, and enables real-time sweat volume monitoring with a sensitivity of -14.6 Ω µL−1 over a detection range of 20–120 µL, maintaining reliable performance during prolonged perspiration. This work provides a promising paradigm for next-generation intelligent textiles that integrate adaptive thermal management and physiological sensing.

Intervertebral disc degeneration (IVDD), frequently accompanied by low back pain, is a global public health challenge. Current therapeutic approaches are unable to halt IVDD progression due to their limited efficacy in promoting extracellular matrix (ECM) remodeling and suppressing inflammatory cascades. To address these issues, we develop an injectable hydrogel-based thermotherapy platform incorporating mesoporous polydopamine (mPDA) nanoparticles (NPs), termed mPDA@Gel. The introduction of mPDA NPs confers dual therapeutic benefits—efficient photothermal conversion and potent reactive oxygen species scavenging, while the prolonged retention of hydrogel matrix within the intervertebral disc (IVD) enables repeated thermotherapy interventions and exerts sustained anti-inflammatory effects following a single injection of mPDA@Gel. In vitro studies demonstrate that multiple mild thermotherapies combined with mPDA NP administration effectively restore ECM metabolic homeostasis in lipopolysaccharide-stimulated nucleus pulposus cells (NPCs) by modulating inflammatory signaling pathways. In vivo evaluation using a rat model of IVDD reveals that a single IVD administration of mPDA@Gel followed by multiple mild thermotherapy cycles significantly reduces disc height loss, minimizes ECM degradation, alleviates inflammatory responses, inhibits NPC apoptosis, relieves non-specific pain, and preserves biomechanical functions. These findings suggest that the proposed system offers a promising minimally invasive therapeutic strategy for the management of degenerative musculoskeletal diseases.

Multistability offers a powerful means to embed adaptability, energy management, and mechanical memory in architected materials. Achieving symmetric and reversible bistability, however, requires precise control of internal stress fields—a capability that remains inaccessible to current additive manufacturing approaches. Here, we introduce a residual-stress programming strategy based on controlled thermal cycling that exploits transient viscoelastic relaxation to deterministically stabilize reciprocal energy landscapes in 3D-printed architected solids. The approach enables geometry-preserving, symmetric bistability in monolithic printed structures, independent of hinges, multimaterial interfaces, or manual assembly, which are typically required to realize multistable architectures. Finite element simulations and reduced-order models capture the coupling between differential cooling dynamics and elastic buckling onset, linking stress evolution to bistable equilibria. We demonstrate this principle in both lattice- and shell-based metamaterials that exhibit sequential, layer-by-layer energy dissipation under impact loading. Together, these results establish a general framework for programming robust multistability into architected materials, enabling new opportunities in energy management, mechanical computing, metamaterials, and soft robotics.

Despite the advantages of additive manufacturing (AM) in creating customized 3D shapes, conventional layer‐by‐layer approaches are limited by low production rates, restricting their broader applications. Volumetric additive manufacturing (VAM) has emerged as a promising technique, enabling the simultaneous photopolymerization of entire volumes, which significantly reduces fabrication time. However, current computed axial lithography requires manual operations per print cycle, such as loading resin into a vial, physically placing and aligning the vial (with or without an index‐matching medium), and removing the printed object, limiting continuous, high‐throughput production of multiple parts. Here, we propose a dispensing volumetric additive manufacturing (DVAM) method that prints and dispenses each part within a droplet in less than a minute. The printing process occurs within a single droplet dispensed from a glass pipette, enabling simultaneous printed object removal and resin replenishment in a second. Light pattern distortion caused by the absence of the index‐matching fluid was corrected through real‐time droplet profile estimation and inverse ray‐tracing within the optical system. We demonstrate rapid serial VAM of 10 different objects within 10 min. This approach establishes a practical pathway toward scalable, high‐throughput volumetric manufacturing, enabling rapid production of complex 3D structures without the operational bottlenecks of conventional VAM workflows.

All‐inorganic CsPbI 2 Br perovskites are promising wide‐bandgap front‐cell candidates for tandem photovoltaics due to their outstanding thermal stability and optimal bandgap. However, their performance is significantly constrained by surface defects and imperfect film morphology, which promote non‐radiative recombination and energy losses. In this work, we propose a surface reconstruction (SRC) strategy employing the ionic liquid dimethylammonium acetate (DMAAc) to fundamentally reconstruct the CsPbI 2 Br surface. Moving beyond conventional passivation, this approach triggers the formation of an intermediate DMAPb(I 2 Br) 1‐x Ac 3x phase on the perovskite surface, followed by its in situ recrystallization into high‐quality CsPbI 2 Br crystals. This phase transformation effectively improves surface morphology, heals ionic defects, and optimizes interfacial energy level alignment. Consequently, SRC‐treated CsPbI 2 Br single‐junction solar cells achieve a champion power conversion efficiency (PCE) of 17.54% with a high open‐circuit voltage ( VOC ) of 1.37 V. Furthermore, by integrating this optimized wide‐bandgap subcell with a narrow‐bandgap organic solar cell, we demonstrate a monolithic all‐inorganic perovskite/organic tandem device that delivers an impressive PCE of 24.20% under AM 1.5G illumination. This study presents a generalized surface reconstruction route to mitigate interfacial losses, offering a viable pathway toward highly efficient and stable multi‐junction photovoltaics.
全无机CsPbI - 2br钙钛矿由于其出色的热稳定性和最佳的带隙，是极有希望用于串联光伏的宽带隙前电池候选者。然而，它们的性能明显受到表面缺陷和不完美薄膜形态的限制，这促进了非辐射复合和能量损失。在这项工作中，我们提出了一种表面重建（SRC）策略，利用离子液体二甲乙酸铵（DMAAc）从根本上重建CsPbI 2br表面。该方法超越了传统的钝化方法，在钙钛矿表面触发中间DMAPb(i2br) 1‐x Ac 3x相的形成，随后其原位再结晶为高质量的CsPbI 2br晶体。这种相变有效地改善了表面形貌，修复了离子缺陷，并优化了界面能级排列。因此，SRC处理的cspbi2br单结太阳能电池在1.37 V的高开路电压下实现了17.54%的冠军功率转换效率（PCE）。此外，通过将这种优化的宽带隙亚电池与窄带隙有机太阳能电池集成，我们展示了一种单片全无机钙钛矿/有机串联器件，在AM 1.5G照明下提供了令人印象深刻的24.20%的PCE。本研究提出了一种广义的表面重建途径来减轻界面损失，为高效稳定的多结光伏发电提供了一条可行的途径。

Scaling flexible perovskite solar cells (F‐PSCs) into high‐performance large‐area modules remains a fundamental challenge due to intrinsic defects and mechanical fragility in perovskite films. We innovatively introduce D‐trehalose (DTA) as a multi‐functional modulator. DTA's unique flexible disaccharide backbone and multi‐hydroxyl structure enable the construction of a dynamic and continuous hydrogen‐bonding network within the perovskite film, which not only regulates crystallization kinetics over large areas but also induces collective lattice polarization. This polarization stabilizes the perovskite framework, releases residual stress, and effectively suppresses ion migration and defect recombination across scalable devices. As a result, we fabricate large‐area flexible perovskite solar modules, achieving a certified efficiency of 18.86% (active area: 619.9 cm 2 ) with a geometric fill factor of 96.95%. Remarkably, the modules retain 92.76% of their initial efficiency after 10 000 bending cycles (radius: 4.9 cm), demonstrating unprecedented scalability and durability. This work provides a molecular crosslinking approach to decouple efficiency and flexibility constraints, advancing the commercialization of high‐performance flexible photovoltaics.
由于钙钛矿薄膜的固有缺陷和机械脆弱性，将柔性钙钛矿太阳能电池（F - PSCs）扩展到高性能的大面积模块仍然是一个根本性的挑战。我们创新地推出D -海藻糖（DTA）作为多功能调节剂。DTA独特的柔性双糖主链和多羟基结构使钙钛矿膜内形成动态连续的氢键网络，不仅可以调节大面积结晶动力学，还可以诱导集体晶格极化。这种极化稳定了钙钛矿框架，释放了残余应力，并有效地抑制了离子迁移和可扩展器件之间的缺陷重组。因此，我们制造了大面积柔性钙钛矿太阳能组件，实现了18.86%的认证效率（有效面积：619.9 cm 2），几何填充系数为96.95%。值得注意的是，在10,000次弯曲循环（半径：4.9 cm）后，模块保持了其初始效率的92.76%，显示出前所未有的可扩展性和耐用性。这项工作提供了一种分子交联方法来解耦效率和灵活性限制，推进高性能柔性光伏的商业化。

Lanthanide‐doped nanocrystals are ideally suited for luminescent nanothermometry, yet their performance is often limited by deleterious cross‐relaxation and back energy transfer among lanthanide ions, which diminish both emission efficiency and thermal sensitivity. Here, we design a core–shell‐shell‐shell nanostructure in which Nd 3+ and Ho 3+ activator shells are spatially separated by a 12 nm‐thick Yb 3+ sensitizer interlayer. This spatial isolation effectively blocks cross‐relaxation between activators and suppresses back energy transfer from activators to sensitizers while enabling efficient interfacial and long‐range energy transfer. As a result, intense dual NIR emissions at 750 and 804 nm are unlocked, yielding a remarkable upconversion quantum yield of 2.29% and an unprecedented brightness of 12311.12 M −1 cm −1 under 170 W cm −2 excitation. Moreover, the Nd 3+ ‐related 804 nm emission shows thermal enhancement governed by lattice phonons, whereas the Ho 3+ ‐based 750 nm emission undergoes thermal quenching dominated by surface defects, resulting in a maximum thermal sensitivity of 3.7%°C −1 at 38°C and remaining above 3.0%°C −1 across the physiological temperature range. The designed nanoprobes also demonstrate excellent stability against variations in irradiation time, pH, and concentration, enabling precise thermal imaging at the cellular level. This work provides a general strategy for constructing high‐performance ratiometric nanothermometers.

Soft robotics has sought to integrate seamless, programmable shape morphing into dynamic, complex structures. We present a design‐for‐manufacturing focused approach leveraging reversible shape memory materials to create soft‐rigid hybrid self‐folding origami robots with fully reconfigurable, reversible actuation. Highly repeatable, closed loop, digital actuation control is achieved through integrated Joule heating of liquid crystal elastomer hinges. Embedded heating traces preserve the planar geometry of origami structures while maximizing the accessible range of motion. We introduce a hybrid direct ink write additive manufacturing system that embeds prefabricated sheet materials, such as flexible printed circuit boards, into 3D printed liquid crystal elastomers to create multi‐material composite structures. This approach enables streamlined fabrication of durable soft robotic origami structures with integrated and reconfigurable actuation, which demonstrate more than 1500 cycles with minimal performance degradation.

Realizing the intrinsic magnetic Weyl semimetal (MWSM) phase in ultra‐thin (SRO) films poses a substantial experimental challenge due to difficulties in controlling Ru stoichiometry. Here, we leverage pulsed laser deposition to stabilize the intrinsic MWSM phase in SRO films down to 4 nm. Optimized growth conditions yield near‐stoichiometric, high‐quality films exhibiting a Curie temperature K and a large residual resistivity ratio ( RRR ). By tuning the Ru content, we observe a transition from the MWSM to a conventional magnetic semimetal. The MWSM phase is evidenced in films as thin as 4 nm by key signatures: large, non‐saturating positive magnetoresistance (95% in 18 nm and 30.6% in 4 nm films at 2 K) and Shubnikov–de Haas oscillations. Analysis of these oscillations reveals high‐mobility Weyl fermions ( ) with small effective masses of and for the 4 nm and 18 nm films, respectively. Density functional theory corroborates these findings, showing Weyl nodes near the Fermi level with similar effective masses (0.12). Altogether, our work demonstrates the stoichiometry‐controlled realization of the intrinsic MWSM state in nanoscale SRO.
