With the rapidly growing demand for flexible energy storage devices in wearable electronics, the development of electrode materials that combine high energy/power density with excellent flexibility has become critical. Inspired by the natural “spiderweb–mucilage” structure, we successfully prepared a lignin-based electrode material via electrospinning, carbonization, and hydrothermal processes. This material achieves efficient dual-mode energy storage by mimicking the synergistic roles of the spider web and mucilage. The material features an rGO-CNFs skeleton with high conductivity (4.02 S·cm–1) and flexibility, serving as a “conductive spider web”, while NiCo-LDHs nanosheets are anchored as “mucilage” for rapid Faradaic reactions. The above components are tightly interconnected by stable M–O–C chemical bonds, endowing the composite structure with excellent mechanical robustness. This design yields exceptional performance: a specific capacitance of 1492.6 F·g–1 at 1 A·g–1, vastly surpassing pure CNFs (161.4 F·g–1) and rGO-CNFs (440.6 F·g–1). Such excellent electrochemical performance originates from the synergistic effect of dual-energy storage and the significantly enhanced electrolyte wettability of the electrode, whose contact angle with the electrolyte is reduced from 133.3° to 34.4°. The assembled flexible symmetric supercapacitor achieves an energy density of 82.67 Wh·kg–1 at 800 W·kg–1 and retains 94.5% capacitance after 2000 cycles, demonstrating excellent stability.

The necessity for high-efficiency, low-power room-temperature (RT) ammonia (NH3) sensors is particularly acute in environmental monitoring, industrial safety, and medical diagnostics. However, conventional chemiresistive sensors frequently require elevated temperatures to initiate reactions, leading to high energy consumption and potential safety risks. Inspired by plant photosynthesis, this paper successfully designs a ternary S-scheme heterojunction for a photo-activated RT NH3 sensor. The design effectively mimics the efficient charge transfer process in photosynthesis, thereby significantly promoting the separation and migration of photogenerated carriers and enhancing the sensing performance. Experimental results demonstrate exceptional performance under illumination: a high response value of 1679% (representing a 20-fold improvement over the dark state), rapid response and recovery times of 2.1 s and 1.9 s, respectively, along with outstanding selectivity, excellent stability, and a detection limit as low as 17 ppb. This work demonstrates a novel, efficient RT photo-activated NH3 sensor and provides innovative insights into designing biomimetic, smart gas-sensing materials and devices.

Hydrogel dressings offer a promising treatment option for the bacterial infection of skin wounds. In this work, we developed multifunctional hydrogels by incorporating carbon nanotubes and protocatechualdehyde into a thiolated chitosan network via multiple interactions. The hydrogels exhibited tunable adhesion (2.7–3.1 kPa), on-demand detachment, as well as restorable antioxidant activity, approximately 80% of its original level. They demonstrated electrical conductivity, in the range of 0.009–0.027 S/m, and maintained stability for nearly 400 s under pressing cycles, suitable for monitoring physiological signals. They demonstrated potent mild photothermal antibacterial capability under near-infrared (NIR) light, with the temperature increasing to 48 ± 0.85 °C and the antibacterial rate up to 99.9%. In an infected mouse wound model, the hydrogels with NIR irradiation achieved ∼ 99.9% wound closure by day 9, outperforming a commercial antibiotic ointment. This work presents a comprehensive strategy for integrated biomass-based wound management systems, combining advanced therapy with smart bioelectronic sensing.

Bacterial infections at wound sites impede healing and pose a serious threat to human health. Conventional antibiotic therapies, however, tend to trigger resistance. Consequently, copper (Cu)-based materials have recently emerged as highly promising alternatives that synergistically kill bacteria and thereby accelerate wound healing. Herein, we developed a core–satellite nanomedicine (PZH) composed of a degradable Cu-doped phosphate-based glass (PBG) core and multiple ZIF-8/hyaluronic acid (HA) satellites. PZH shows pH-triggered behavior: at physiological pH its structure remains intact and Cu2+ release is minimal, whereas the acidic microenvironment of infected wounds triggers disassembly, releasing Cu2+ and generating •OH radicals through peroxidase-like (POD-like) activity. This dual-functional ionic-catalytic mechanism achieves potent bactericidal effects against both Gram-positive and Gram-negative bacteria. At 6 μg/mL, PZH eliminates >99% of Staphylococcus aureus. In vitro assays further confirm that PZH is cytocompatible and accelerates cell migration. To overcome the application limitations of conventional Cu nanoparticle suspensions, PZH was loaded into a thermosensitive F127 hydrogel to yield PZHF, which preserves the POD-like activity and enables minimally invasive, injectable delivery to irregular wound geometries. In vivo tests further demonstrated that the biocompatible PZHF hydrogel displayed good antibacterial properties and promoted wound healing. As a smart, clinically translatable Cu-based nanomedicine, this system provides a precision therapeutic strategy for treating bacterially infected wounds.

Develop AlCl 3 -assisted mechanochemical strategy enabling efficient one-pot conversion of recalcitrant cellulose to HMF. • Synergistic interplay between Lewis acidity and mechanical stress disrupts H-bonding networks and lowers crystallinity, markedly enhancing the chemical reactivity of cellulose. • Optimization of the Brønsted/Lewis acid balance by controlled HCl addition achieves a high HMF yield of 62.8% from mechanochemically pretreated cellulose. • This green and scalable approach can be broadly extended to diverse lignocellulosic biomass wastes, including waste paper, corncob residue, bamboo powder, and corn straw, to efficiently produce HMF. 5-Hydroxymethylfurfural (HMF) is a pivotal bio-based platform chemical, yet its direct production from inexpensive and abundant cellulose remains challenging due to the intrinsic recalcitrance of cellulose and the competing degradation of intermediates and products under acidic conditions. Herein, we report an AlCl 3 -assisted mechanochemical strategy that couples catalytic Lewis acidity with ball-milling mechanical force to activate cellulosic feedstocks, enabling their efficient one-pot conversion to HMF. Detailed structural characterizations demonstrate that the synergistic interplay between AlCl 3 and mechanical stress disrupts the extensive hydrogen-bonding network and partially cleaves β-1,4-glycosidic linkages, leading to pronounced reductions in cellulose crystallinity and degree of polymerization and, consequently, markedly enhanced chemical reactivity. The resulting mechanochemically pretreated cellulose (BMM-AlCl 3 ) was directly converted into HMF without additional catalysts during the reaction step, as the Al species introduced during pretreatment served as the catalytic sites, affording a yield of up to 46.8%. By further optimizing the Brønsted/Lewis acid balance through controlled HCl addition, the HMF yield increases to 62.8%. Importantly, this pretreatment strategy is broadly applicable to diverse lignocellulosic biomass resources, including waste paper pulp, corncob residue, bamboo powder, and corn straw, consistently delivering high HMF yields. This work establishes an efficient and potentially scalable mechanochemical route for the valorization of cellulose and lignocellulosic biomass into HMF.

Temporary plugging and diverting fracturing is an effective strategy to enhance fracture network complexity and expand the stimulated reservoir volume. However, in ultra-deep reservoirs, temporary plugging agents face a critical contradiction between maintaining high pressure-bearing capacity and achieving rapid deplugging under ultra-high temperatures, as dense structure is usually accompanied by slower degradation rate. And also, after deplugging, fractures tend to close under ultra-high in-situ stress, significantly reducing conductivity. Inspired by the stage-specific functionality and core utilization strategy of chia seeds, this study proposes an innovative, resource-efficient “soft shell–rigid core” plugging structure. A dense yet rapidly self-degradable soft shell, formed from high-temperature-resistant polymers and degradable crosslinkers, is employed to encapsulate a high-strength core to form a core–shell structure. This design balances high pressure resistance with rapid degradation, while providing sustained fracture support post-deplugging. The prepared Gel@CP undergoes a sequential process of “injection-plugging-degradation-fracture support.” It exhibits excellent fluid compatibility and suspension stability in the carrier fluid (static >3 h). Under 200 °C and 170,000 ppm salinity, the material reaches a maximum plugging pressure of 21.5 MPa, maintains 20 MPa for over 240 min, and shows a degradation rate above 99.9 % within 12 h, converting into environmentally benign water-soluble polymer fragments. After degradation, the exposed CP core effectively supports fractures, maintaining conductivity above 876 mD·cm under 70 MPa closure stress. This delicate biomimetic core–shell design endows this material with superior performance simultaneously in pressure bearing, fast degradation, and post-deplugging fracture support, which is reported for the first time, providing an innovative, sustainable, and practical solution for temporary plugging and propping under extreme reservoir conditions.

Effectively separates biomass oxidation from parasitic OER using cuprous-integrated spinel heterostructures. • Suppresses OER by thermodynamically elevating the energy barrier for *OH deprotonation. • Unlocks a record-broad anodic potential window for stable high-voltage electrosynthesis. • Sustains ampere-scale currents (>4 A) with near-unity FDCA selectivity (>90%). • Demonstrates exceptional stability up to 2200 mV in a high-flux flow electrolyzer. The industrial viability of electrochemical biomass valorization is fundamentally throttled by the parasitic oxygen evolution reaction (OER), which severely confines the stable operational window. Here, we report a strategy for expanding the operational horizon of ampere-scale biomass electrorefining using a cuprous-integrated NiCo-spinel heterostructure (Ni 1.5 Co 1.5 O 4 -Cu 2 O) that effectively decouples these competing pathways. By engineering a cuprous-integrated heterostructure, we establish a functional dichotomy wherein synergistic Ni/Co sites activate 5-hydroxymethylfurfural, while the Cu 2 O moiety selectively suppresses OER by thermodynamically elevating the *OH deprotonation barrier. This design unlocks a record-broad anodic window and, when integrated into a flow cell, delivers an exceptional 2,5-furandicarboxylic acid yield (> 90%) at industrial-scale currents (> 4 A) across an extended voltage range (up to 2200 mV). In situ spectroscopy and density functional theory calculations validate this mechanism, confirming that optimized interfacial coupling drives the selective 5-hydroxymethyl-2-furancarboxylic acid pathway. This work provides a generalizable electronic-structure engineering strategy for high-performance, scalable organic electrosynthesis.

AN-DVB-AO amidoxime resin, widely used for industrial Ga recovery in China, was synthesized. • AN-DVB-AO resin was employed for Ga adsorption from bauxite Bayer liquor in Southwest China. • The failure mechanism of the AN-DVB-AO amidoxime resin in bauxite Bayer liquor was elucidated. In recent years, the rapid development of high-tech industries including semiconductors and new energy has boosted the demand for gallium (Ga), a critical strategic metal. Bayer liquor derived from bauxite processing is the major primary source of Ga. Given increasing resource scarcity and environmental restrictions, developing efficient and eco-friendly Ga recovery technologies has attracted extensive interest. In this study, an acrylonitrile–divinylbenzene (AN–DVB) resin was synthesized via suspension polymerization and further amidoxime (AO)-functionalized with hydroxylamine hydrochloride to obtain AN–DVB–AO resin. Adsorption–desorption behavior and deactivation mechanism of the resin were systematically investigated in real bauxite Bayer liquor. Results demonstrated that the AN–DVB–AO resin exhibited high selectivity for Ga. The maximum adsorption capacity reached 13.1 mg/g after 12 h of amidoximation. After 14 reuse cycles, the Ga adsorption capacity decreased to 6.22 mg/g, representing 52.6% reduction. The primary reason for resin deactivation was the formation of a dense aluminum hydroxide (Al(OH) 3 ) layer after multiple cycles, which blocked active sites and degraded selective Ga adsorption. The aluminum (Al) content on the resin surface increased by 42.7% after 14 cycles, confirming that Al precipitation was the dominant cause of deactivation. The adsorption mechanism was clarified, providing a theoretical basis and technical support for practical Ga recovery from Bayer liquor using AO-modified resin.

Branched-chain amino acids play critical roles in cardiac physiology and diseases. Genetic deficiency in the valine catabolic enzyme ACAD8 is clinically associated with isobutyryl-CoA deregulation and cardiomyopathy in humans, but its roles in cardiac disease remain undefined. Here, we show that the levels of ACAD8 are reduced in humans and male mice with cardiac hypertrophy. Cardiomyocyte-specific Acad8 knockout in male mice exacerbates cardiac hypertrophy and cardiac dysfunction underwent pressure overload. Mechanistically, Acad8 deficiency leads to the accumulation of its substrate isobutyryl-CoA, which enhances histone isobutyrylation, chromatin accessibility and TEAD2 enrichment at promoter regions of hypertrophy-related genes, which increases the sensitivity to hypertrophic stress in mouse hearts and cardiomyocytes. Conversely, ACAD8 overexpression in cardiomyocytes suppresses isobutyryl-CoA accumulation and histone isobutyrylation, thereby attenuating cardiac hypertrophy and dysfunction. These results elucidate the roles of ACAD8 deficiency in cardiac diseases and reveal histone isobutyrylation in transcription regulation and cardiac pathology.

Six new phenylazophenol derivatives with tunable substituents were designed to address highly selective Li + /Na + separation. • Structure-performance analysis identifies typical phenol HS-5 as optimal extractants and establishes clear design rules. • The new HS-5/TOPO synergistic system achieves 95.3% single-stage extraction and 99.6% Li + recovery in two stages. • The mechanism underlying the high Li + /Na + selectivity and stability was elucidated by combined DFT and experimental analyses. As brines creasingly constitute source of lithium, the selective extraction of Li + from Na + -rich, high-salinity matrices has become a critical challenge in materials design. In this study, six phenylazophenol derivatives with systematically tunable were designed and synthesized to explore Li + /Na + separation from lithium-containing mother liquor, with structures by 1 H NMR and mass spectrometry. Systematic evaluation of electronic and steric substituent effects established clear structure–performance relationships, identifying 2-phenylazo- 4-trifluoromethylphenol (HS-4) and 4-methanesulfonyl-2-phenylazophenol (HS-5) as the most efficient extractants. A hetero-coordination synergistic extraction system based on HS-5 and trioctylphosphine oxide (TOPO) was further developed and optimized. The optimized system achieved a single-stage Li + extraction efficiency of 95.3%, a Li + /Na + separation factor of 293, and a stripping efficiency of 95.4%. Two-stage cross-flow extraction enabled 99.6% Li + recovery with only 9.3% Na + co-extraction, demonstrating that near-complete lithium removal can be realized with minimal stages. The HS-5/TOPO system retained 79.9% extraction efficiency over ten extraction-stripping cycles without significant degradation. Mechanistic investigations revealed a 1:2 Li + –ligand stoichiometry by Job's method, while DFT calculations showed that HS-5 coordinates to Li + in a bidentate manner through phenolate-O and azo-N, with two P O donors from TOPO completing the distorted tetrahedral coordination environment. These findings underscore the considerable potential of phenylazophenol-based systems for efficient lithium recovery from brines.

An electrocatalytic Cu-GHM system with tunable nanoconfined spaces is constructed. • The electrified system enables 73%–100% degradation of 13 emerging contaminants. • 100 h of continuous operation is demonstrated without loss of structural integrity. • The electrified system also exhibits high energy efficiency (0.07 kWh/m 3 ). • DFT calculations and MD simulations elucidate the degradation mechanism. Persulfate-based advanced oxidation processes are promising for removing refractory contaminants from aquatic systems, however, their performance is often constrained by limited reactive oxygen species utilization and restricted mass transfer. Although spatial confinement engineering of electrocatalytic membranes has improved persulfate activation, the underlying structure–property–performance relationships remain insufficiently understood. Here, we report an electrochemical peroxomonosulfate activation system employing a three-dimensional graphene hydrogel-supported copper nanoparticle membrane (Cu-GHM) as the cathode. The system demonstrated broad applicability, achieving 73%–100% degradation across 13 representative emerging contaminants in real water matrices. Its long-term stability was further confirmed through a 100-h continuous operation test specifically using ranitidine as the model pollutant. By regulating pore architecture through controlled compression, the nanoconfined space was tuned from 13.5 to 5.0 nm, revealing a strong dependence of catalytic performance on confinement scale. The smallest pore size (5.0 nm) resulted in an 8.1-fold enhancement in degradation kinetics, attributed to increased local reactant concentration, improved mass transport, and facilitated interfacial electron transfer. Comprehensive spectroscopic analyses and molecular dynamics simulations elucidated the confinement-enhanced catalytic pathways and mass-transfer behavior. This study provides mechanistic insights into synergistic nanoconfinement and electric-field effects, offering a rational framework for designing energy-efficient electrified membrane systems for water treatment.

Biological materials composed of inorganic nanofillers and biopolymeric matrix ( e.g. , bone and crab shells) generally display excellent mechanical performance. However, conventional chitin/nanohydroxyapatite composites exhibit limited mechanical properties, primarily due to the random distribution and aggregation of nanohydroxyapatites within the chitin matrix. Herein, we develop uniaxially and biaxially oriented chitin/nanohydroxyapatite hydrogels through a facile stretching strategy. The influences of pre-stretching/transversely strains and nanohydroxyapatite morphology (spherical, rod-shaped, and sheet-like nanohydroxyapatites) on the structure and mechanical properties of hydrogels were systematically investigated. Finally, the bone plates were prepared through sequential solvent exchange, drying, and machining of biaxially oriented hydrogels containing sheet-like nanohydroxyapatites. The resultant plates showed high tensile strength (102 MPa) and toughness (7.9 MJ/m 3 ) and exhibited good biocompatibility and biodegradability. This work presents a straightforward strategy for fabricating high-performance plates by controllably arranging nanohydroxyapatites within a chitin matrix.
