Superfluorescence is a cooperative emission phenomenon arising from the coherent coupling of excited dipoles and has historically been observed only under optical excitation in carefully engineered quantum systems. Here, we report the first observation of superfluorescence triggered by ionizing radiation in lead-halide perovskite nanocrystal (NC) superlattices. Using CsPbBr3 NC assemblies with long-range structural and electronic order, we show that secondary electrons generated by high-energy photons can induce intense cooperative emission bursts with an unprecedented scintillation lifetime of ∼40 ps, defining a new class of coherent scintillating metamaterials. Side-by-side optical and scintillation measurements reveal a direct analogy between ionizing and intense optical excitation, both producing high excitonic densities that drive superfluorescent emission at mild, technologically accessible cryogenic temperatures. The finding that stochastic ionization cascades can seed coherent many-body optical responses with radiatively accelerated luminescence and large Stokes shifts establishes a pathway toward ultrafast, reabsorption-free, quantum-ordered scintillators for next-generation radiation detectors.

Organoid-based strategies offer unique advantages for bone regeneration by recapitulating the multicellular architecture and dynamic microenvironment of native tissue. However, their clinical translation remains constrained by reliance on immunogenic, animal-derived matrices and limited immunomodulatory capacity. We propose a non-immunogenic, xeno-free, and cytokine-free plant-derived bioink composed of aloe vera gel, laponite nanoclay, and gelatin methacrylate (GelMA) for constructing immune-instructive bone organoids. This bioink enables long-term reprogramming of macrophages toward an M2 phenotype without exogenous cytokines, establishing a stable pro-regenerative immune microenvironment that enhances mesenchymal stem cell osteogenesis and extracellular matrix (ECM) maturation. The construct supports robust 3D tissue organization, immune-guided osteoinduction, and functional integration in vivo. Notably, this is the first demonstration of a plant-based bioink platform for organoid bioengineering, offering a scalable and translationally viable alternative to Matrigels. Our strategy redefines osteoimmunomodulatory material design and establishes immune-responsive bone organoids as a next-generation solution for large bone defect repair.

Organic mechanoluminescence (ML) enables light emission directly triggered by mechanical force, offering opportunities for stress sensing and wearable technologies. However, conventional organic systems based on fluorescent guests typically suffer from low efficiency, thermal quenching, and poor signal reproducibility. Here, we report a guest-centered design strategy in which thermally activated delayed fluorescence (TADF) guests are integrated into piezoelectric host crystals for the construction of efficient, robust ML materials. The resulting systems exhibit greatly enhanced light output, strong thermal amplification of emission, and stable performance over hundreds of compression cycles. Photophysical experiments and theoretical analyses reveal that TADF guests strengthen electromechanical coupling and improve mechano-exciton utilization via efficient harvesting of excited states. Extending this strategy to blue, green, and red emitters achieves spectrally tunable ML across the visible range. This work establishes a general molecular design principle for high-performance organic ML with potential impact on reusable stress sensors, wearable electronics, and structural health monitoring.

Global warming poses a critical threat to food security as the heat stress impairs photosynthesis and reduces the effectiveness of conventional agrochemicals. Addressing this challenge requires new materials strategies that can deliver nutrients precisely while protecting plants from heat-induced oxidative stress. We developed an effective microneedle platform that penetrates leaves, dissolves rapidly, and releases nutrients on demand under mild near-infrared light. This integrated system not only delivers iron to promote photosynthesis but also scavenges harmful reactive oxygen species, safeguarding chloroplast function. Demonstrated in cotton, the platform significantly improved growth and chlorophyll levels. More broadly, the plant-material biointerface strategy can enhance nutrient efficiency, reduce chemical losses, and strengthen leafy crop resilience under climate stress.

Black color is the most typical feature of natural and synthetic melanins, which results from the complex packing and chemical disorder of the molecular structure within melanins. From nature and beyond nature, breaking through the black color boundary, expanding the scope of inherent functions, and establishing clearer structure-function relationship of melanin is necessary but hard due to the inherent chaos structure caused by random covalent coupling and supramolecular assembly. Herein, starting from melanin-inspired monomers, we chose and assembled typical organic acceptor molecules (TCNB/TCNQ) with melanin-inspired donor molecules to prepare a series of colorful melanin-inspired pigments through the co-crystallization strategy. The resulting colorful melanin-inspired pigments exhibited multiple colors and different rod-like morphologies compared with many melanin-like polymers. Particularly, green DHI/TCNQ powder presented excellent photothermal efficiency (∼69.8%) for antibacterial application. This work would provide new structure-function tailoring strategy toward the design of melanin-like polymers with highly ordered structures and desirable properties.

Strong, reversible, and adaptive adhesives can be designed by tailoring non-covalent interactions. This preview demonstrates a supramolecular strategy for programming adhesion, which integrates various non-covalent interactions and dynamic covalent bonds to achieve robust adhesion performance across diverse surfaces. This work demonstrates how molecular-level designs enable sustainable, reconfigurable adhesives and highlights data-driven methods for bridging molecular interactions with macroscopic adhesive properties.

We introduce AdaCarbon, a high-throughput automation system designed to accelerate the development of GDEs for CO2 electrolysis. AdaCarbon consists of seven collaborative robots that automate GDE fabrication, characterization, and zero-gap CO2 electrolysis testing. Using this platform, we fabricated and tested 90 GDEs with varying Cu–Ag metal compositions and Nafion-Sustainion ionomer bilayers to optimize ethylene production at 200 mA cm−2. Our results show that higher Cu and Nafion content increased ethylene selectivity by 5%–9%. Furthermore, AdaCarbon accelerates GDE development by a factor of three compared to manual workflows, demonstrating its potential to significantly enhance CO2 electrolysis research.

Natural soils form hierarchical structures through physicochemical self-assembly—a principle that can be harnessed to design sustainable, high-performance building materials. We present a scalable approach that tunes kaolinite self-assembly via controlled chemical environment and guar gum (GG) addition, enhancing strength while retaining 3D printability. Physicochemical, rheological, and mechanical analyses show that pH regulates clay self-assembly by altering particle surface charge, whereas GG restructures networks through polymer bridging. Multiscale characterization reveals that although similar microstructures can develop across compositions when stabilized with sufficient biopolymer at different pH, the pathways leading to their formation differ. Networks are formed primarily through colloidal interactions (van der Waals and electrostatic forces) or induced by biopolymer bridging. Despite appearing structurally similar, biopolymer-assembled networks exhibit significantly greater strength—exceeding 110% improvement—compared to those formed through colloidal interactions. These results highlight that the origin of microstructure critically governs performance, introducing a new designing principle for sustainable, printable materials.

Bimetallic halides combine the merits of single-metal halides and multi-metallic systems, offering tunable emission, high efficiency, and stability for optoelectronics. We designed a new bimetallic halide, (C8H20N)4MnBiCl9, and investigated its optical and physical properties under extreme stimuli. With pressure up to 10.0 GPa, its emission color shifts from blue (ambient) to red, and intensity increases at lower temperature. A high photoluminescence quantum yield (PLQY) of ∼58% with green emission is achieved at 1.8 GPa, over 5-fold higher than ambient. Under ambient pressure, strong emission response is observed across 130–470 K, showing dual pressure- and temperature-dependent responsiveness. Pressure-induced distortions of [BiCl5]2− and [MnCl4]2− polyhedra, along with reduced interunit distance, enhance energy transfer, yielding stronger emission and color shifts. These properties highlight its potential for information encryption, optical sensing, and system calibration in extreme environments.
