Circularly polarized luminescence (CPL) materials, which exhibit their unique chiroptical properties, display great potential for applications in optoelectronics and bioimaging. However, it remains a significant challenge to synthesize CPL materials with high dissymmetry factors (g lum ) and photoluminescence quantum yields (PLQY) simultaneously. Herein, we report a deep-eutectic-solvent (DES)-assisted self-assembly protocol integrated with an active-learning (AL) framework that enables the targeted fabrication of G-quadruplex (G4) supramolecular gels with high g lum and PLQY. AL pinpointed the optimal synthesis parameters in just four iterations, dramatically accelerating material development. The top-performing gel achieved a g lum of 0.29, setting a new benchmark for nucleoside/nucleotide-based CPL materials. The maximum PLQY reached 10.64%, which represents a substantial level of performance. Furthermore, by integrating SHapley Additive exPlanations (SHAP), we elucidated the relationship between reaction parameters and target properties. Building on this result, we also demonstrated multicolor fluorescence resonance energy transfer (FRET) by incorporating dyes, successfully developing a series of multicolor CPL-active materials. This work not only provides new insights into the design of bio-based chiral CPL materials but also highlights the promising role of artificial intelligence in advancing material development.

Moisture-electric generator (MEG) is attractive sustainable energy sources, but environmental fluctuations cause unstable output, and low power/short supply limit practical use. Here, we developed a MEG device based on an activated carbon structured-gradient hydrogel, which achieved milliampere and milliwatt level electrical energy output and continuous voltage output for over 1 month. Unlike conventional isotropic materials, this structure promotes the directional migration of water and ions, effectively accelerating charge accumulation and enabling continuous power generation. Concurrently, the synergistic effect between the humidity-induced hydrogel and the slow anodic corrosion of the aluminum electrode establishes an H+/Al3+ gradient diffusion, further improving the electrical output performance. A single MEG device (with an area of approximately 1 cm2) can stably output a voltage exceeding 1.6 V across a wide humidity range (20–80% RH) and a broad temperature spectrum (−40 to 60 °C), with continuous operation for over 740 h. Significantly, the single MEG achieves 22.1 mA/cm2 current and 3.2 mW/cm2 power density, both an order of magnitude higher than previous MEGs. Large-scale integration technology provides an effective pathway for amplifying the electrical output performance of MEG arrays, connecting 100 MEG units in parallel yields a continuous current of ∼45 mA, with a series configuration of 120 units providing ∼192 V. The MEG array can successfully power a 5 W black light bulb and a wireless sensing system directly, showing great potential application in smart agriculture. This work provides a idea for advancing the development of high-performance MEG devices and real applications.

The high-value utilization of wheat straw, which is a major agricultural residue in China, is of significant importance. This study presents a mild and efficient process for the oxidative fractionation of wheat straw using a synergistic alkaline deep eutectic solvent (DES) combined with Fenton-like reagents (OH– + H2O2 + Fe2+). Under mild conditions (90 °C, 1 h), the process achieved 85.78% delignification while retaining 91.76% of the cellulose. Notably, the resulting pulp showed excellent digestibility, yielding 96.12% glucose and xylose with a very low cellulase loading (6 FPU of CTec3), which outperforms most state-of-the-art systems. Comprehensive investigations confirmed the critical role of alkaline DES and the enhancing effect of the Fenton-like reagents. Furthermore, the DES could be recycled ten times with only a minor reduction in fractionation efficiency. This work offers a promising strategy for the mild and sustainable biorefining of lignocellulosic biomass.

Gel-based materials are promising candidates for flexible sensors in wearable health monitoring owing to their inherent flexibility, conductivity, and biocompatibility. However, integrating rapid fabrication, robust mechanical properties, and strong interfacial adhesion into a single gel system remains a significant challenge. Here, we report a liquid metal nanoparticle-initiated rapid polymerization strategy to fabricate organic-ionogels without external initiators or cross-linkers. The resulting gels exhibit ultrafast gelation (∼3 min), remarkable toughness (∼27 MJ m–3), high lap shear strength (∼2.4 MPa), and reliable strain sensing performance. Density functional theory (DFT) calculations reveal that strong intermolecular interactions, including hydrogen bonding and electrostatic forces, underpin the enhanced mechanical and adhesive properties. Furthermore, we demonstrate the practical utility of these liquid metal–organic-ionogels (LM-AHG) in a wearable health monitoring device (WHMD) integrated with machine learning algorithms. The system enables real-time, high-precision classification of joint rehabilitation stages based on strain signals, achieving 100% accuracy in stage identification. This work provides a rapid and scalable fabrication route for high-performance organic-ionogels and establishes a material-algorithm codesign paradigm for next-generation personalized rehabilitation and smart wearable electronics.

2,5-Furandimethanol (BHMF) is an important biobased chemical, which can be widely used in the production of fuels, drugs, and polymers. However, BHMF production mainly relies on chemical methods for reduction of 5-hydroxymethylfurfural (HMF), which suffer from low selectivity and environmental concerns. In this study, alcohol dehydrogenase AdhP from Escherichia coli was screened and engineered at residue W84 to generate the 84A mutant, exhibiting a 1.3-fold increase in the catalytic reduction rate compared with the wild-type AdhP at pH 7.0 and 35 °C. Coupling W84A with glucose dehydrogenase (GDH) created the recombinant E. coli AD84 whole-cell catalyst, which might efficiently transform high-titer HMF (1 M) into BHMF (118 g/L) in a yield of 93.3% under 30 °C and pH 7.0 in 6 h. Furthermore, a chemoenzymatic one-pot approach was developed to transform waste bread into BHMF, achieving the valorization of food waste through tandem catalysis with a deep eutectic solvent (DES) chemocatalyst and whole-cell biocatalyst. In a deep eutectic solvent (Betaine:Malic acid:Glycerol)-H2O (10:90, wt/wt) system, waste bread (20.0 g/L) was transformed to 5-HMF at 190 °C for 15 min, with a yield of 26%. Subsequently, E. coli AD84 cells catalyzed the bioreduction of waste bread-derived HMF into BHMF, acquiring a yield of 97% (0.26 g of BHMF/g of bread waste). This work constructed a robust reductase biocatalyst for efficiently transforming high titer of HMF and waste bread-derived HMF into BHMF, providing a sustainable approach for food waste valorization.

Inspired by the catechol chemistry of mussel adhesive proteins, we designed a multifunctional hydrogel that combines antibacterial activity, self-healing, excellent biocompatibility, enhanced mechanical properties, adjustable adhesion, and controlled drug release. A P(AA-co-UH) primary network was synthesized through the copolymerization of acrylic acid and urushiol, while a P(CNC-PB) secondary network was assembled from cellulose nanocrystals, polyvinyl alcohol, and borax. The two networks were interlaced to form an interpenetrating polymer network, which substantially enhanced mechanical performance, achieving a tensile strength of 61.45 kPa and excellent fatigue resistance. The cis -hydroxy groups in cellulose nanocrystal and polyvinyl alcohol, along with the hydroxyl groups of urushiol, engage in dynamic covalent borate ester bonds with borate ions in borax solution. This dynamic covalent crosslinking provides a way to control the concentration of catechol groups, thereby tuning the adhesive performance. Moreover, the incorporation of borax modifies the pore structure and swelling behavior of hydrogels, enabling controlled drug release. This hydrogel exhibits excellent self-healing properties, wet adhesion, and drug-loading capacity. It can self-heal within 5 h, with wet adhesion increasing from 14.13 kPa to 17.51 kPa and drug loading capacity rising from 10.9 mg/g to 19.6 mg/g. Antibacterial and cytotoxicity assays confirmed its favorable biocompatibility and antimicrobial efficacy. In summary, these multifunctional hydrogels are highly promising for smart medical dressing applications.

Non-invasive collection of weak electroneurographic signals is crucial for cognitive neuroscience. However, animal scalps are often covered by dense hair, which presents a substantial barrier in the scalp-electrode interface for accurate electrophysiological acquisition. Although scalp hair removal is common practice in clinical settings, it has detrimental effects on the test subjects and is infeasible in many non-clinical scenarios. Here we report a hair-adaptable and adhesion-tunable (HAAT) scalp-electrode interface that can accurately acquire electroneurographic signals from hairy skins of animal and human. By synthetically integrating dynamic covalent bonds and ionic conduction channels in the copolymer poly(sodium thioctate- co -sulfobetaine methacrylate), we implement the key functionalities of the HAAT interface including penetration of dense hair layers, strong conformal skin-electrode adhesion, on-demand painless detachment, and sensitive neuroelectric coupling. We achieve stable and precise electroneurographic signals acquisition from human, monkey and mouse’s scalps with various hair densities. The accurate event-related potential monitored during monkey vision-attention tasks facilitates the study of monkey brain activity. These results demonstrate the HAAT interface as an outstanding platform for conducting non-invasive research on animal cognition.

Achieving both robust mechanical and osteogenic properties of bone adhesives remains challenging. Here, we developed a novel polyurethane-based bone adhesive (PCLU- g -nHA) by covalently incorporating aminated nanohydroxyapatite (nHA-NH 2 ) into a biodegradable poly (ε-caprolactone) urethane (PCLU) network. This design promoted uniform nHA dispersion and strong organic–inorganic integration through urea linkages, significantly enhancing compressive modulus (4.91 ± 0.10 MPa) and adhesive strength (3.41 ± 0.24 MPa in lap-shear). The adhesive cured rapidly under mild conditions with minimal heat release. PCLU- g -nHA showed improved biocompatibility and stimulated bone marrow mesenchymal stem cells (BMSCs) osteogenic differentiation in vitro . Transcriptomics revealed upregulation of extracellular matrix remodeling and collagen synthesis pathways. In vivo , PCLU- g -nHA enhanced bone regeneration and osseointegration in rabbit femoral condyle defect and tibial fracture models, outperforming a commercial PMMA bone cement. This study offers a scalable strategy for developing highly bioactive and tough bone adhesives with clinical translational potential.

Early fault detection of lithium-ion batteries (LIB) is crucial for the safe operation of electrical measurement systems. Detecting the dimethyl carbonate (DMC) vapor in the LIB electrolyte can effectively improve the early warning time. However, the response speed of the existing semiconductor resistive gas sensors is significantly slower compared with the commonly used temperature and pressure sensors. To address the issue within gas sensors, a DMC gas sensor with an extremely fast response speed was developed based on mixed-phase bismuth oxide, which can effectively respond to 20 ppm DMC within 6 s. Moreover, the sensor successfully triggered the alarm approximately 15 min before the start of thermal runaway and within 22 s after the mechanical rupture of the battery in the simulated abuse test, demonstrating the application potential of gas sensor in the early fault warning of LIB.

Mango, as a highly perishable climacteric fruit, incurs significant postharvest losses due to rapid ripening and spoilage. To address this challenge, environmentally friendly bioactive coating technology has emerged as a promising preservation strategy. This study developed a novel coating based on fish gelatin (FG), enhanced by a metal-phenolic network (MPN) formed through the coordination between tannic acid (TA) and Fe 3+ ions. By systematically optimizing the molar ratio of TA to Fe 3+ , the formulation with a 0.2% Fe 3+ concentration (FG/MPN 2 ) was identified as optimal, exhibiting the best system stability (zeta potential: +16.32 ± 1.21 mV) and micro-uniformity (PDI < 0.3). Structural analyses via Fourier-transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy confirmed the formation of a stable composite structure within the FG matrix. Benefiting from this, the FG/MPN 2 coating demonstrated significantly enhanced barrier properties, interfacial adhesion, and excellent antioxidant activity. Finally, the coating was applied to mango preservation (25°C, 60% RH). The preservation results indicated that the coating could significantly inhibit weight loss, maintain higher fruit firmness (17.92 ± 0.50 N) on the 12th day, effectively delay color yellowing, and reduce lipid peroxidation damage, thereby extending the shelf life.

The selective electrocatalytic oxidation of glycerol (GOR) into high-value chemicals is crucial for sustainable biorefineries, yet achieving high selectivity, particularly for C1 products like formic acid, remains a significant challenge. Herein, we report the rational design and facile one-step hydrothermal synthesis of ZrO2@Co-MOF heterostructures, where ZrO2 nanoparticles act as core sites influencing Co-MOF growth. The optimized ZrO2@Co-MOF(0.11) catalyst exhibits unprecedented performance for GOR, achieving 98.7% selectivity and near-unity faradaic efficiency for formic acid production at industrially relevant current densities, alongside excellent long-term stability. Comprehensive electrochemical evaluations, ex situ characterization methods, and in situ/operando spectroscopic investigations reveal a pivotal innovation: the ZrO2 interface not only modulates the electronic structure of Co centers and tailors MOF morphology but, critically, directs and stabilizes the in situ electrochemical reconstruction of the Co-MOF into highly active CoOOH/Co(COO)2 species. Furthermore, theoretical calculations elucidate that this engineered interface significantly lowers the energy barrier for critical C–C bond cleavage (ΔG = 0.03 eV), thereby suppressing C3 intermediates and driving the reaction pathway selectively toward formic acid. This work unveils a powerful strategy in hetero-interfacial engineering of MOF-derived materials for precise and efficient biomass valorization.

Unlocking the cross-linked network structure of low-rank coal is pivotal for its high-value utilization, yet this process is severely constrained by mass transfer resistance. To address this challenge, a “carrier-permeation” synergistic strategy is proposed herein, which integrates high-permeability dimethylformamide (DMF) with high-activity deep eutectic solvents (DES). Molecular dynamics simulations indicate that DMF may function as a molecular carrier, promoting the deep penetration of viscous DES components into the coal matrix. Experimentally, this synergistic effect induces substantial physical restructuring: particle size is reduced by more than 82% (to 22.57 μm) and the aromatic interlayer spacing ( d 002 ) is increased to 0.355 nm via effective disruption of stacking interactions. Chemically, the system achieves an exceptional desulfurization rate of 90.81%, along with the selective cleavage of ether bridges and long aliphatic chains (CH 2 /CH 3 ratio minimized to 2.71). Consequently, pyrolysis pathways are substantially redirected by this structural remodeling, shifting product distribution from low-value alkanes to high-value olefins (50.47%) and esters (24.09%). A molecular-scale deconstruction system is elucidated, offering a novel approach for clean and value-added utilization of lignite.
