Gallium-based liquid metals offer high electrical conductivity and intrinsic fluidity, making them promising materials for coaxial 3D printing of flexible conductive fibers in soft electronics. However, their low viscosity and high surface tension limit their processability in coaxial 3D printing. Here, we present a nonaqueous high-internal-phase emulsion ink, composed of 85 wt % eutectic gallium-indium dispersed in a stearic acid/isopropanol continuous phase. Stearic acid molecules form a lubricating interfacial monolayer, enabling long-term chemical stability and shear-induced plastic flow. The ink is compatible with high-resolution direct ink writing and coaxial 3D printing with tunable core diameters (0.15–0.7 mm) and core-to-fiber area ratios up to 0.788. Printed fibers show excellent stretchability (≥200%), fatigue resistance (>1,000 cycles), and conductivity (6.0 × 105 S·m−1). Functional demonstrations include wearable textiles and deformable electromagnetic coils for wireless energy harvesting. This work provides a general and scalable approach to printing highly conductive, elastic fibers for emerging soft electronic applications.

Optoelectronic devices have demonstrated significant academic and practical value in a wide range of applications, including optical communication, environmental sensing, imaging, display technologies, and energy harvesting. However, traditional rigid optoelectronic devices are inherently limited by their bulkiness and mechanical inflexibility, making them unsuitable for wearable electronics. By contrast, optoelectronic fiber devices offer distinct advantages in terms of size, weight, and adaptability, with 1D structures and weavability, enabling them to conform better to human motion and complex deformations. Specifically, optoelectronic fiber devices, such as fiber-shaped photodetectors, fiber-shaped solar cells, and fiber-shaped light-emitting devices, have shown great promise in real-time monitoring, energy harvesting, and intelligent sensing. This comprehensive review thoroughly examines optoelectronic fiber devices, providing an in-depth overview of their operating mechanisms, material considerations, and fabrication strategies. It focuses on the latest advancements in device structures, performance optimization, and system integration, highlighting key research areas and recent breakthroughs. Moreover, the review discusses the integration of optoelectronic fiber devices into multifunctional fabrics for applications in wearable electronics, smart textiles, and health monitoring, as well as the challenges of large-scale fabrication, device durability, and energy efficiency. Finally, it underscores the crucial research directions that are essential for advancing the commercial viability and widespread application of optoelectronic fiber devices in cutting-edge technologies.

Targeted penetration enabled by special bioactive coatings and regulation of the tumor immune microenvironment are crucial for effective nanorobot therapy. Recently, researchers reported a modular train-style nanorobot in which exosomal “heads,” catalytic “bodies,” and photothermal “tails” were spatially segregated to optimize individual functions. Consequently, distinct propulsion, targeting, and microenvironment-modulating capabilities were integrated across connected modules, resulting in enhanced tumor penetration, metabolic reprogramming, and immune activation, thus leading to a satisfactory therapeutic effect in orthotopic colorectal cancer models.

Synthetic hydrogels provide powerful material platforms to engineer cellular microenvironments with control over stiffness, viscoelasticity, porosity, degradability, and biochemical signals. Here, we demonstrate how orthogonal crosslinking reactions allow fabrication of covalent adaptable networks to tailor photopolymerizable bioresin formulations relevant for tissue engineering. Specifically, we synthesize multifunctional poly(ethylene glycol) (PEG) macromers containing dynamic boronate ester bonds and dithiolane and norbornene moieties that allow for photopolymerization and projection-based biofabrication. These materials are used to print human mesenchymal stromal cells (MSCs) in formulations where the ratio of elastic versus adaptable crosslinks is engineered to study and manipulate MSC spreading, actin structure, and macroscopic material-level deformation. We demonstrate how material and print parameters, peptide ligands, actomyosin-modulating drug treatments, and cell types influence cell-material interactions and emergence of morphogenesis that is uniquely enabled by viscoelasticity. The presented materials introduce a versatile strategy for spatiotemporal control over dynamic mechanical properties in cell-laden matrices.

Thermal management is crucial for electronics, especially in the artificial intelligence era of high-power computing. Ultra-low thermal resistance materials are essential for graphics processing units (GPUs)/central processing units (CPUs) but face trade-offs between interfacial resistance, conductivity, mechanical compliance, and durability. Herein, we present a carbon-silicone composite pad with vertically aligned graphite flakes engineered through a two-step strategy: in situ crack formation via ultrasonic treatment followed by precision mechanical polishing. This approach synergistically realizes smooth interfaces and superior graphite deformability, thereby fundamentally addressing the intrinsic trade-off between bulk compressibility and interfacial contact integrity in vertically structured carbon-based thermal interface materials. The optimized composite shows outstanding performance (total thermal resistance = 1.8 mm2K/W at 50 psi, and bulk thermal conductivity exceeds 460 W/mK), high compressibility (45% strain at 50 psi), and fairly good thermal cycling stability. Our findings establish a transformative route toward next-generation thermal interface materials, offering a critical enabler for energy-efficient artificial intelligence hardware development.

Large language models (LLMs) provide new possibilities for accelerating materials research, yet their application in complex materials science remains limited. Here, we developed the collaborative multi-agent and robot system (MARS), a knowledge-driven hierarchical architecture coordinating 19 LLM agents with 16 domain-specific tools for closed-loop autonomous materials discovery. MARS combines scientific knowledge with decision-making capabilities while mitigating hallucination through retrieval-augmented generation with a customized knowledge base. In experimental validation, the system optimized perovskite nanocrystal synthesis within 10 iterations and designed a biomimetic “core-shell-corona” structure for water-stable perovskite composites in 3.5 h versus conventional methods requiring 4–6 months. This acceleration automates literature review and experimental planning, allowing researchers to focus on creative thinking while interacting through a natural language interface. This work establishes an integrated AI-driven framework for accelerating materials innovation and presents a paradigm for AI-enabled scientific discovery.

Traditional thermal camouflage materials often fail in outdoor settings due to surface heat accumulation from solar irradiation, necessitating the development of camouflage materials that can withstand direct sunlight and high temperatures. Herein, a gradient porous nanocomposite foam with continuous dual gradients in MXene content and porosity is prepared through electrostatic field-driven gradient polymerization. This foam demonstrates Janus spectral characteristics: the polymer-rich surface with high mid-infrared emissivity and strong solar reflectance enables efficient radiative cooling, while the MXene-rich surface with low emissivity suppresses thermal signatures. The dual-gradient architecture enables thermal rectification capabilities with a rectification factor of 28%, thereby redirecting excess heat from the sunlight-exposed surface to the radiatively cooled side to mitigate heat buildup and enhance camouflage performance. The gradient foam reduces surface temperature by up to 8.8°C compared to conventional uniform foam. This study offers a promising strategy for developing spontaneous-cooling thermal camouflage systems for challenging outdoor environments.

Ultrafine Pt nanocrystals with defined crystal structures are desirable for use as a catalyst of various electrochemical reactions; however, their preparation remains challenging, especially for fine control over the crystal size and dominant facet. Here, we report a fast heating and cooling (FHC) method to produce ultrafine (∼2.0 nm) {100} facets-dominant Pt nanocubes (Pt NCs) loaded on single-walled carbon nanotubes (SWCNTs). Experimental and computational investigations demonstrate that the grooves of SWCNT bundles act as a template that guides the growth of Pt NCs along the tube axis direction, while a small amount of oxygen facilitates the {100} facet formation and FHC stabilizes the size and shape of NCs. The resulting monodispersed Pt NCs confined on SWCNT networks exhibited high mass activity, low onset potential, high current density, and exceptional durability in ammonia oxidation reaction. This work offers a novel approach to synthesizing ultrafine Pt nanocrystals with excellent electrocatalysis performance.
