Dry fabrication minimizes active gas loss during patch preparation. • Selective encapsulation enables differentiated CO₂/ClO₂ dual-gas release. • Centripetal moisture absorption triggers humidity-responsive gas generation. • Differential gas release extends fresh-cut cabbage shelf life to nine days. Premature CO₂/ClO₂ loss during wet-casting fabrication bottlenecks moisture-responsive packaging scale-up. To address this, this study prepared polyacrylate nanoparticles loaded with 85.8% sodium chlorite (200–400 nm) and alginate-gelatin films (tensile strength 9.7 MPa, water vapor permeability 19.9 g·mm/m 2 ·day·kPa). Dry nanoparticles, sodium bicarbonate, and citric acid were then loaded into alginate-gelatin pouches to create a sandwich patch, minimizing fabrication-stage gas loss. In humid environments, the polyacrylate core absorbed threefold more water than the film, driving unidirectional moisture influx. Selective encapsulation—sodium chlorite in polyacrylate/film bilayers versus sodium bicarbonate in film monolayer—enabled differentiated release: CO₂ peaked at 15% (v/v) within 12 h, while ClO₂ plateaued at 14.9 ppm ( w / v ) on day 3. Applied to fresh-cut purple cabbage, the differentially released gases suppressed respiration, extending shelf life from 3 to 9 days without visible wilting or decay. This dry-processing route enables multi-component gas differentiated release in smart packaging. Download: Download high-res image (88KB) Download: Download full-size image

Objective The aim of this study is to explore the potential target of Tongmai Xianxiang in the prevention and treatment of postherpetic neuralgia (PHN) by gas chromatography–mass spectrometry (GC‐MS) and network pharmacology. Methods Quantitative analysis using GC‐MS was employed to obtain the chemical components of Tongmai Xianxiang, and target site prediction was conducted; PHN‐related targets were collected from relevant disease databases; the anti‐PHN targets of Tongmai Xianxiang were obtained through network pharmacology methods, and molecular docking was performed on the main targets. Results A total of 633 active components were screened by GC‐MS, corresponding to 772 targets. By searching the disease database, a total of 169 PHN‐related disease targets were obtained after removing duplicates. A total of 53 core genes, including SLC6A4, MAOA, DRD2, and ALB, were obtained by intersecting the corresponding target and PHN target. Through molecular docking, the results indicate that ALB has the lowest free binding energy with Z‐butylidenephthalide, 2‐undecanol, and 1,6,10‐dodecatrien‐3‐OL, 3,7,11‐trimethyl‐, (E)‐. Conclusion Tongmai Xianxiang can prevent PHN by multitarget, multiprocess, and multipathway. This study provides new ideas and new targets for the intervention of Tongmai Xianxiang in PHN.

Photothermal catalytic CO2conversion into chemicals that provide added value represents a promising strategy for sustainable energy utilization, yet the development of highly efficient, stable, and selective catalysts remains a significant challenge. Herein, we report a rationally designed p-n junction heterostructure, T-CZ-PBA (SC), synthesized via controlled pyrolysis of high crystalline Prussian blue analogues (PBA) precursor, which integrates CuCo alloy, ZnO, N-doped carbon (NC), and ZnII-CoIIIPBA into a synergistic architecture. This unique configuration offers dual functional advantages: (1) the abundant heterointerfaces provide highly active sites for enhanced CO2and H2adsorption/activation, and (2) the engineered energy band structure optimizes charge separation and transport efficiency. The optimized T-C3Z1-PBA (SC) achieves exceptional photothermal catalytic performance, demonstrating a CO2conversion rate of 126.0 mmol gcat⁻1h⁻1with 98.8% CO selectivity under 350 °C light irradiation, while maintaining robust stability over 50 h of continuous operation. In situ diffuse reflectance infrared Fourier transform spectroscopy (in situ DRIFTS) investigations have identified COOH* as a critical reaction intermediate and elucidated that photoexcitation accelerates charge carrier dynamics, thereby substantially promoting the conversion of key intermediates (CO2* and CO*) and overall reaction kinetics. This research provides insights for engineering high-performance heterostructured catalysts by controlling interfacial and electronic structures.

Pyrolysis, thermal reduction, and mechanochemical force are commonly used for biomass utilization, materials synthesis, and spent Li-ion batteries recycling. However, the effect of mechanical treatment on pyrolysis gas generation and thermal reduction remains unclear. Herein, we study the effect of mechanical treatment on the biomass pyrolysis reduction of LiCoO2. The mechanical milling generates oxygen vacancies in the LiCoO2 lattice. In addition, the mechanical treatment can regulate the pyrolysis gas of sawdust in terms of increasing the content of H2, CH4, and CO while decreasing the CO2 content. The oxygen vacancies and pyrolysis gas are beneficial for the thermal collapse of the LiCoO2 structure, leading to the rapid and complete separation of Li and Co, thereby increasing the recovery efficiency to above 98%. The understanding of the interplay of mechanical force, oxide structure, and pyrolysis gas composition helps design green approaches to enabling metal and organic resource recovery and utilization.

The preparation conditions of zeolite are the key factors affecting the adsorption performance of organic sulfur from natural gas. The influence of crystallization time, pH and Si/Al ratio of ZSM-5 zeolite preparation on the crystallinity, which is further related to the dimethyl sulfide adsorption performance in gas was explored for the first time. After conditional screening, the suitable conditions for organic sulfur adsorption are crystallization time of 36 h, Si/Al of 50, and pH as 13, and the breakthrough capacity of ZSM-5 is 8.23 mg/g. The Si/Al ratio has the greatest impact on the adsorption performance. With Si/Al ratio reduced from 200 to 50, the breakthrough time increased by 146%. The breakthrough time of ZSM-5 in methane is reduced by 12.5% compared with nitrogen. After the 5 cycles, the breakthrough time of the ZSM-5 decreases by less than 5%, indicating that the ZSM-5 can be reused for a long time in the natural gas purification industrial application process. This research provides research directions and guidance for the optimization of zeolite preparation conditions and the development of new organic sulfur adsorbents.

Amine-functionalized sorbents are investigated widely for CO2 capture from flue gas, to mitigate the crisis of global CO2 emission, with the advantages of excellent adsorption and regeneration performance. However, the presence of O2 in flue gas (3–10%) would induce the degradation of the sorbents, and some previous works proposed the strategies at the sacrifice of partial CO2 adsorption capacity. Herein, we focused on the oxidation behavior of PEI-functionalized silica in the long-term operation and analyzed the degradation mechanism by characterizing the oxidized sorbents. The sorbent proved to be oxidative stable under a lower temperature of air exposure, but the oxidative degradation would indeed occur at more harsh temperatures (above 90 °C). This study demonstrated that CO2 capture from O2-containing flue gas was feasible by controlling the operating temperature (below 75 °C), and the effective capacity of above 135 mg/g could be maintained in the cyclic CO2 capture.

Flavonoids exhibit high structural complexity not only from their diverse cores and substitutions but also from glycosylation with various glycans, leading to numerous isomeric species. This study employed cyclic ion mobility mass spectrometry (cIM-MS) to achieve high-resolution separation of flavonoid and flavonoid glycoside isomers with subtle structural differences. A multipass cIM strategy featuring adjustable drift path lengths significantly enhanced both resolution and operational flexibility. Notably, multiple ion mobility peaks were frequently observed for individual pure compounds, which were identified as charge-site isomers arising primarily from sodium adduction at distinct molecular sites. Computational chemistry and collision cross section (CCS) analysis were integrated to elucidate the three-dimensional configurations corresponding to these different mobility peaks. The results reveal that sodium ions, by coordination with multiple electronegative oxygen atoms within the molecule, stabilize specific gas-phase conformations, leading to distinct CCS values resolvable by ion mobility spectrometry. This work advances the understanding of charge-site isomerism by providing atomic-level insights into metal ion–molecule interactions. It also establishes an integrated cIM-MS and computational modeling framework, which substantially enhances analytical depth for complex isomeric systems.

An automated SHS–GC–MS method was developed for VOC tracking during UPR curing. • Seven VOCs were simultaneously quantified with low detection limits and good accuracy. • Compound-specific VOC emission behaviors during artificial stone curing were revealed. • Styrene peaked at 953 μg g⁻¹ during the early stage of the curing process. • VOC emissions were observed to persist for 29 days. To enable rapid and reliable tracking of volatile organic compounds (VOCs) emitted from unsaturated polyester resin (UPR)based artificial stone, an automated static headspace gas chromatography–mass spectrometry (SHS–GC–MS) method was developed and systematically optimized. Key parameters, including incubation temperature (60°C), incubation time (30 min), and inlet temperature (250°C), were optimized to achieve efficient extraction and separation of seven target VOCs: dichloromethane, methyl acetate, ethyl acetate, ethylbenzene, styrene, benzaldehyde, and styrene oxide. The method demonstrated excellent linearity ( R ² = 0.991–0.998), low limits of detection (0.18–0.36 µg g -1 ) and quantification (0.54–1.11 µg g -1 ), along with satisfactory accuracy (recoveries of 88.3–104.6%) and precision ( RSD < 12.2%). Uncertainty analysis revealed that calibration and standard preparation were the dominant contributors to overall measurement uncertainty. Application of the method to UPR-based artificial stone during curing showed a pronounced time-dependent decline in VOC emissions. Styrene was the dominant component, peaking at 953 µg g -1 in the early curing stage and decreasing to baseline levels after approximately 29 days. Dichloromethane and ethyl acetate declined to near detection limits within 8 days, ethylbenzene persisted for about 13 days, while methyl acetate and benzaldehyde remained detectable for up to 24 days. These results indicate that the early curing stage poses the highest emission risk. Overall, the proposed method provides a robust analytical tool for VOC tracking, supporting emission control and environmental risk assessment of UPR-based artificial stone.

Chlorinated volatile organic compounds (CVOCs), such as chlorobenzene, are highly toxic and persistent, with low-temperature catalytic oxidation being a key abatement strategy. However, SO 2 often coexists with CVOCs in industrial flue gases, leading to sulfur poisoning of Mn-based oxides. The effectiveness and limits of catalyst regeneration remain unclear. In this study, Mn 2 O 3 is used as a model catalyst, and a controllable gas-phase presulfation strategy is proposed to construct a “fresh–poisoned–regenerated” tri-state system for evaluating surface sulfur species. Fresh Mn 2 O 3 -F shows low light-off temperatures for chlorobenzene oxidation (T 50 = 278 °C, T 90 = 326 °C), but SO 2 pretreatment significantly reduces activity, with increasing SO 2 concentrations further inhibiting the reaction. None of the presulfated samples reach 90% conversion within the tested temperature window. After acid regeneration, sulfur content decreases from 2.37 wt% to 1.30 wt%, leading to partial recovery of activity (T 90 rises to 375 °C, Ea decreases to 59.36 kJ/Mol). In situ DRIFTS reveals that SO 2 forms stable surface sulfates, which block active sites, occupy oxygen vacancies, and hinder lattice oxygen migration, resulting in partial deactivation. The regeneration process removes weakly bound sulfur species, but residual sulfates and structural changes limit full recovery. This work provides a framework for evaluating sulfur-tolerant design and regeneration pathways for Mn-based catalysts.

Recent advancements have positioned nonaqueous amine-based absorbents as promising candidates for energy-efficient CO2 capture. However, detailed physicochemical data are still essential to support accurate modeling for scaling up the process. Diffusivity (D) and physical solubility (H) of N2O and CO2 in organic solvents were determined by using a stirred cell. Gas solubility ratios (HCO2/HN2O) in these solvents exhibit an inverse correlation with the solvents’ Hoy solubility parameters. Changes in the DCO2/DN2O ratio and D^(1/2)/H in various solvents are governed by interactions between gas properties and solvent polarity. Specifically in the 2-hexyloxyethanol (2-HE)/2-(ethylamino)ethanol system, DN2O was found to be inversely proportional to solvent viscosity with a power of 0.6. The ratios of the derived combined parameter D^(1/2)/H for CO2 and N2O increase with solvent polarity. This correlation framework allows reliable prediction of transport properties in the 2-HE based nonaqueous system, supporting kinetic study and scalable carbon capture design.

Nonaqueous amine-based absorbents offer advantages over aqueous monoethanolamine (MEA), but they inevitably evolve into water-lean systems when treating humid flue gas, presenting a challenge for long-term performance stability. In this work, a formulated water-lean absorbent, 50B-40BE-10 W, was evaluated for CO 2 capture from simulated humid flue gas in an upgraded lab-scale continuous plant over 720 h, benchmarking it against 30 mass% MEA. Key operational parameters and water balance behavior were systematically investigated to inform rational process design. Under a framework of absorbent-tailored regeneration strategy coupled with dynamic water-balance control, the 50B-40BE-10 W solvent achieved a remarkably low desorber heat duty, about 50–65% reduction compared to MEA. Critically, a dynamic water-management strategy was proposed and demonstrated, involving controlled discharge of desorber overhead condensate following a membrane dehydration process. This approach successfully maintained stable water content of ∼10 wt% in the solvent over a 100-h period, effectively addressing the challenge of water accumulation in water-lean systems. Furthermore, NMR analysis of the absorbent after ∼1700 h of operation, even under high‑oxygen exposure, indicated no catastrophic degradation. The compelling performance and stability demonstrated at the bench-scale pave a solid pathway for further development of this advanced water-lean capture technology.

This study was to evaluate the feasibility of controlling carcinogenic nitrosodiethylamine (NDEA) formation from greenhouse gas adsorbent 3-diethylaminopropylamine (DEAPA) by pre-O 3 in subsequent chlorination/chloramination processes. The result indicated that the NDEA yields (0.4 %) during chlorination was 1.3 times of that during chloramination (0.3 %); pre-oxidation with 4 mg/L O 3 significantly cut down its formation; the reduction rates were up to 67.5 and 48.5 %, respectively. OH scavenger greatly augmented the final NDEA amount from 1.86 to 5.05 μg/L during ozonation , while its roles on subsequent processes differed with disinfection methods as well as O 3 (g) dosages. Most of co-existed substances inhibited NDEA generation, except NO 2 − , CO 3 2− and SO 4 2− , which slightly promoted during ozonation. Basing on Gaussian calculation, GC/MS and UPLC-Q-TOF-MS analysis, the influencing mechanisms of pre-O 3 on NDEA formation in subsequent disinfection processes were proposed. In addition, the calculated toxicity analysis as well as the whole toxicity was applied to evaluate the possibility of pre-O 3 on risk control.
