Replacing α -hydroxyl group with an α , β -unsaturated group markedly enhanced the decomposition reactivity of dimer. • α , β -Unsaturated group promoted C α ─C β bond cleavage, while α -hydroxyl group led to β -O-4 bond cleavage. • α , β -Unsaturated group accelerated reaction rate ∼14-fold at 120 °C. • Dehydration of α -hydroxyl group into α , β -unsaturated group facilitated lignin depolymerization. Lignin is a promising feedstock for the production of monomeric aromatics, which can be further upgraded into valuable chemicals or fuel hydrocarbons. In this work, the effect of the α , β -unsaturated group on the conversion of lignin and its β -O-4 model dimers into monomeric aromatics was investigated. The results showed that replacing the native α -hydroxyl group with an α , β -unsaturated group markedly enhanced the decomposition reactivity of the dimer. Specifically, the α , β -unsaturated group promoted C α ─C β bond cleavage, whereas the native α -hydroxyl group led to β -O-4 bond cleavage. This significant enhancement in reactivity was consistent across varied reaction conditions and enabled near-quantitative yields of monomeric aromatics from the dimer containing the α , β -unsaturated group. Kinetic analyses indicated apparent first-order kinetic behavior for both dimers, showing that the α , β -unsaturated group accelerated the reaction rate by a factor of approximately 14 at 120 °C. Moreover, an α , β -unsaturated group generated in situ via dehydration of the α -hydroxyl group during pretreatment effectively facilitated lignin depolymerization. This work outlines a promising approach for developing efficient lignin depolymerization technologies targeting monomeric aromatics.

Although cGAS-STING immunotherapy holds immense potential, its efficacy is severely compromised by pathway evasion. To overcome this, we engineered a core-shell bilayer nanobomb (M/ZIF/MnO 2 @DBCO) via a template-assisted approach, integrating MSC1094308 into ZIF-8 cores followed by MnO 2 shell deposition and DBCO functionalization. In a simulated tumor microenvironment, ZIF-8 loading accelerated Mn 2+ release from MnO 2 , increasing the cumulative release by nearly 30% within 8 h compared to pristine MnO 2 . Cellular assays demonstrated rapid bio-orthogonal targeting of azide-modified tumors, achieving lysosomal escape within 6 h postuptake. Subsequently, MnO 2 -mediated glutathione (GSH) depletion and hydroxyl radical (·OH) generation, combined with Zn 2+ induced mitochondrial oxidative stress, produced cytotoxic reactive oxygen species (ROS) that triggered immunogenic cell death. Furthermore, Mn 2+ , Zn 2+ , and dsDNA released from damaged mitochondria cooperatively activated the cGAS-STING pathway. Concurrently, MSC1094308 inhibited ESCRT-mediated negative regulation, as evidenced by a ∼0.2 decrease in the p-STING/VPS4B-RFP colocalization coefficient, confirming the blockade of cGAS-STING evasion. In vivo studies revealed that the nanoplatform profoundly stimulated antitumor immunity, increasing tumor-infiltrating cytotoxic T lymphocytes approximately 8-fold versus untreated controls after 21 days. This work establishes an integrated strategy harnessing Zn 2+ /Mn 2+ synergy, nanobomb reactivity, and ESCRT inhibition to circumvent cGAS-STING evasion, offering a promising paradigm for cancer immunotherapy.

The biocatalytic conversion of green methanol, a promising feedstock, into high value-added products is seen as an attractive way to establish sustainable biomanufacturing. Although natural and engineered microorganisms can utilize methanol, efficiently converting C1 carbon into valuable chemicals in growing cells remains challenging because non-native pathways often suffer from low carbon utilization and limited catalytic stability. Here, we report the integration of an engineered enzyme cascade into resting cells and its coupling with a screened alcohol oxidase enzyme to develop an efficient and stable enzyme-resting cell cascade system for methanol conversion, achieving customizable production of L-erythrulose (C4 sugar) or L-sorbose (C6 sugar). This system shows a stimulated carbon atom economy for L-erythrulose production from methanol and significantly improved stability compared to free enzyme catalysis. By integrating enzyme cascades with durable resting cells, this strategy provides a versatile platform for converting methanol and other C1 substrates into value-added products.

Monodisperse microspherical silver powder with a high yield of 99.9%, high tapped density, and excellent dispersibility was prepared via a controlled liquid-phase reduction route. • Ag(111)-based simulations revealed dispersant adsorption behavior, while experiments confirmed their regulation of silver particle growth. • The prepared silver powder was further used to construct a flexible wearable sensing materials, enabling real-time monitoring of various human motions. High-quality monodisperse microspherical silver powders hold considerable promise for conductive pastes and flexible electronics. However, the concurrent realization of high yield, dense packing, and excellent dispersibility remains challenging. Herein, we report a controlled liquid-phase reduction route based on an ammoniacal silver complex, using formaldehyde as reductant and stearic acid as dispersant. The resulting silver powder exhibits an ultrahigh yield of 99.9%, a tapped density of 6.0 g/cm 3 , and excellent sphericity and dispersibility. Moreover, this exceptional performance is enabled by a stable organic interfacial layer formed through carboxyl-group adsorption on the silver surface, which suppresses disordered agglomeration and promotes uniform particle growth. Notably, a flexible strain sensor constructed from this powder delivers a rapid response time of 125 ms and stable real-time monitoring of various human motions. This work demonstrates a practical pathway for the controlled synthesis of high-performance spherical silver powder for wearable sensing applications.

Selective separation of precious metals from chloride-rich acidic media remains challenging because of the complex aqueous speciation of metal ions and the interference of competing ions. In this study, a polyethyleneimine (PEI)-functionalized tannin-based phenolic resin (TPR@PEI), enriched with O/N binding sites, was synthesized via Schiff base reactions for the selective separation and recovery of Au(III) and Pd(II) from complex acidic chloride solutions. The effects of key synthesis parameters, including tannic acid (TA) dosage, formaldehyde (FA) volume and crosslinking time, on adsorbent structure and Au(III)/Pd(II) adsorption performance were systematically investigated. Under the optimized synthesis conditions (1 g TA, 5 mL FA, and 2 h crosslinking time), TPR@PEI exhibited rapid adsorption kinetics, reaching equilibrium within 40 min for both metal ions. The adsorption behavior was well described by the pseudo-second-order kinetic model and the Langmuir isotherm model, with maximum adsorption capacities of 416.67 mg g −1 for Au(III) and 270.27 mg g −1 for Pd(II) at pH 2. More importantly, TPR@PEI showed superior selectivity toward Au(III) (> 99%) and Pd(II) (> 87%) in both binary and multicomponent systems, and maintained removal efficiencies remaining above 90% over five adsorption-desorption cycles. Combined characterization and density functional theory calculations (DFT) revealed that the excellent separation performance was governed by the synergistic effects of electrostatic attraction, redox interaction, and coordination/chelation enabled by the cooperative O/N-rich binding sites. These results demonstrate that TPR@PEI is a promising adsorbent for the highly selective separation and recovery of precious metals from complex chloride-rich acidic solutions.

Detection of 3-hydroxy-2-butanone (acetoin), a characteristic volatile metabolite of Listeria monocytogenes (LM) , represents a promising non-invasive strategy for monitoring contamination levels of foodborne pathogens in food. However, current sensing materials suffer from poor selectivity and insufficient sensitivity at trace concentrations. Herein, a series of Pd-loaded Cd 2 GeO 4 (Pd/CGO) chemiresistive gas sensors that achieves highly selective and sensitive acetoin detection was reported. Among them, the 0.5 wt% Pd/CGO-based sensor exhibits a high response, with an ultrafast response time and a detection limit as low as 10 ppb. The sensor also demonstrates excellent selectivity over common interfering gases, good reproducibility, and robust long-term stability. Mechanistic investigations combining O 2 -TPD, XPS, and DFT calculations reveal that Pd loading not only increases the proportion of chemisorbed oxygen species on the CGO surface, which enhances the overall sensing response, but also serves as new active sites. This work demonstrates that rational Pd modification combined with dual-site engineering offers a promising paradigm for designing high-performance metal oxide gas sensors for pathogen biomarker detection in food.

This work modified lignin using a facile two-step grafting method with high yield. • Modified lignins show improved radical scavenging activity and thermal stability. • DDSA modification enhances hydrophobicity and reduces glass transition temperature. • NR/PL and NR/DPL exhibit higher vulcanization efficiency. • NR/DPL shows a superior anti-thermo-oxidative performance. Developing high-performance lignin-based anti-thermo-oxidative agents offers a promising pathway for both the valorization of lignin and the sustainability of rubber materials. To enhance the thermo-oxidation resistance of natural rubber (NR), this study tailored lignin's structure via facile molecular engineering approaches, producing p -aminodiphenylamine-grafted lignin (PL) and (2-dodecen-1-yl)succinic anhydride (DDSA)/ p -aminodiphenylamine co-grafted lignin (DPL) with high grafting yields. Their structures were verified by FTIR, 2D-HSQC and elemental analysis. The introduction of p -aminodiphenylamine significantly improved the thermal stability of lignin, while the incorporation of DDSA markedly enhanced its hydrophobicity and reduced its glass transition temperature. In NR composites, both PL and DPL impart a high vulcanization efficiency and a rubber reinforcing effect. Notably, the NR/DPL sample after thermo-oxidative aging exhibits an improvement of 138.5% in tensile strength and 44.2% in elongation at break compared to the NR/L benchmark, and shows the highest anti-aging coefficient (0.52) outperforming NR/L by threefold. DSC, FTIR and TG-MS were applied to illustrate the thermo-oxidative behavior of the NR samples. This work provides a molecular engineering strategy for shaping lignin into an effective bio-based anti-thermo-oxidative agent.

The development of lightweight, broadband, and high-efficiency electromagnetic wave
(EMW) absorbing materials requires both strong attenuation and effective
impedance matching. To address this challenge, ZIF-67 was introduced
into a resorcinol-formaldehyde (RF) sol–gel system and carbonized
at 600–800 ° C to construct nanoscale Co/C nanoparticle-embedded
carbon aerogels (Co/C-CA). The resulting Co/C-CA composites contain
ZIF-67-derived nanoscale Co/C nanoparticles anchored within a hierarchical
porous carbon aerogel network, which helps preserve the three-dimensional
skeleton and creates magnetic-dielectric interfaces. The optimized
Co/C-CA-700 composite exhibited a minimum reflection loss (RL min ) of −60.9 dB and a maximum effective absorption
bandwidth (EAB) of 6.34 GHz. The improved absorption is attributed
to balanced impedance matching, interfacial polarization, dipole relaxation,
magnetic resonance, and conductive loss regulated by carbonization
temperature, together with cross-scale coupling between nanoscale
Co/C units and the carbon aerogel framework. This work provides a
structure-oriented strategy for lightweight and broadband EMW absorption.

A photocatalytic self-propelled nanomotor adsorbent was developed for Pd(II) recovery. • Self-propulsion overcomes diffusion-limited adsorption kinetics. • EPR reveals the ROS-mediated mechanism of long-term propulsion. • Selective Pd(II) recovery is achieved in complex acidic wastewater. The recovery of palladium (Pd) from complex acidic industrial wastewater is severely restricted by sluggish interfacial mass transfer and inherent diffusion-limited adsorption kinetics. To address this long-standing bottleneck, asymmetric N/Se-codoped resorcinol-formaldehyde nanomotors (Se-RF@NMs) were rationally fabricated via an emulsion-confined anisotropic growth strategy for photocatalytic self-propulsion-boosted Pd(II) recovey. Under light irradiation, the photoresponsive resin framework enables continuous in-situ H 2 O 2 generation. Meanwhile, the adsorption-induced in-situ reduction of Pd(II) further accelerates catalytic H 2 O 2 decomposition to generate oxygen microbubbles, endowing nanomotors with sustainable autonomous motion and dynamically promoting interfacial ion transport. EPR characterization confirms that photogenerated holes and reactive oxygen species sustain the cyclic H 2 O 2 generation-decomposition system, effectively stabilizing the self-propulsion behavior of Se-RF@NMs. Benefiting from the synergistic coupling of photocatalytic self-propulsion and N/Se-based selective coordination adsorption, the optimized Se-RF@NMs achieve a superior Pd(II) adsorption capacity of 196.75 mg g −1 , as well as excellent selectivity in multi-metal competitive systems and practical industrial wastewater matrices. This work elucidates a photocatalysis-driven active mass transfer enhancement mechanism, establishing a feasible paradigm to break the intrinsic diffusion limitation of conventional adsorption. It provides new insights into the rational design of intelligent self-propelled catalytic adsorbents for high-efficiency precious metal recovery in complex and harsh water environments.

Modified g-C 3 N 4 /HKUST-1/diatomite composite is rationally fabricated. • CN x , HKUST-1 and diatomite synergistically enhance adsorption and photocatalytic oxidation. • Light-induced ·O 2 − and ·OH participate in oxidation of formaldehyde. Effective removal of indoor formaldehyde (HCHO) is critical for improving indoor air quality and protecting human health. In this study, a ternary composite material CN x @DH-4 was constructed by rationally combining K-doped modified carbon nitride (CN x ), diatomite, and HKUST-1. This combination integrates adsorption enrichment with visible light-driven photocatalytic degradation. Structural and surface characterization analyses confirmed the uniform dispersion of CN x and HKUST-1 on the diatomite carrier, while XPS revealed the interface electronic interactions, which regulated the electronic structure. Owing to the optimized CN x loading, extended visible-light absorption, and abundant nitrogen vacancy sites acting as active centers, CN x @DH-4 achieved a HCHO removal efficiency of 83.34%. EPR measurements confirmed the light-induced generation of ·O 2 − and ·OH radicals, suggesting that reactive oxygen species play an important role in HCHO oxidation. CN x @DH-4 maintained its optical and structural stability during 10 cycles and exhibited excellent durability. This study provides a practical strategy for designing multifunctional adsorption-type photocatalysts, where the adsorption sites, defect engineering, and structural stability interact synergistically to achieve continuous and efficient indoor HCHO purification.

The fragility of aerogel is inherited from the bead-like structure, where the fine interconnections between these spheres act as weak points under load. Herein, aerogels with tailored fibrous structures were proposed to offer mechanical properties that surpass those of raw material by order of magnitude. Wherein, sodium alginate derived nanoribbons and fibrous template were progressively exfoliated in the wake of hydrogen bonding self-assembly and solvent-induced differentiation respectively. Interconnected nanofibrous architecture, which enabling efficient load transfer and stress distribution, endowed the silicone/phenolic (SiR/PR) aerogels with ultra-high compressive strength. Given facile ambient pressure drying technology and exceptional compressive strength (9.2 MPa), fibrous SiR/PR aerogels performed superior among reported ablative aerogels. Additionally, considering the uniform distribution of phenolic pyrolyzed carbon within the matrix, aerogel escaped from devitrification up to 1400 °C, thereby preserving fibrous morphology and larger specific surface area after annealing. This strategy for constructing microfibrous aerogels will pave the way for the robust fibrous aerogel with devitrification resistance.

Rapid and reliable detection of methane (CH 4 ), a key clean energy source and potent greenhouse gas, is of great importance for industrial safety and environmental protection. In this work, a high-performance CH 4 gas sensor is developed based on hollow ZnO nanobowls decorated with Pd nanoparticles, synthesized via a template-assisted strategy followed by mild impregnation. The hollow nanobowl architecture features a uniform particle size (~350 nm), ordered mesopores (~3.4 nm), and a high specific surface area of 104.06 m 2 g −1 , which effectively enhances gas diffusion and surface reaction kinetics without relying on complex heterojunctions or bimetallic systems. The introduction of Pd increases the oxygen vacancy content from 29.41% to 41.48%, provides additional active sites, and facilitates electron transport. Moreover, Pd catalyzes O 2 dissociation via a spillover effect and lowers the activation energy for C H bond cleavage in CH 4 , while the work function difference between Pd and ZnO induces a Schottky barrier at the interface, dynamically modulating the sensor conductivity. Benefiting from the synergistic effects of morphological regulation and interfacial electronic modulation, the sensor exhibits a high response of 67% to 1000 ppm CH₄ at an operating temperature of 253.5 °C, along with an ultrafast response/recovery time of 2/10.5 s and a wide detection range of 20–10,000 ppm. In addition, the sensor demonstrates good selectivity and excellent long-term stability, with less than 10% signal fluctuation over 30 days. Building upon the reliable concentration discrimination validated by CNN-1D models, an LSTM-based short-term dynamic prediction framework was further introduced to evaluate temporal early-warning performance under rapid methane concentration variations. The results demonstrate that the proposed sensor–algorithm integration can effectively capture dynamic concentration evolution and accurately predict the 5000 ppm alarm threshold across multiple diffusion rates, highlighting its potential for early-warning applications in confined spaces.
