This study examined the effects of different impregnation methods and solutions on texture of soft-pack (retort) canned abalone. Results showed that room temperature and pressure immersion, with either pure water or sodium alginate, did not significantly affect abalone meat hardness. Ultrasonic immersion caused myofibril rupture, leading to a looser structure. Combining sodium alginate with ultrasonic immersion decreased hardness. Vacuum immersion utilized negative pressure to create larger voids, accelerating sodium alginate absorption and enhancing water retention, achieving tenderization without lipid oxidation. Overall, sodium alginate and vacuum impregnation proved most effective for improving abalone texture.

Liquid-phase advanced oxidation processes (AOPs) offer a promising approach for enhanced VOC removal. However, hampered by low gas-liquid mass transfer efficiency and insufficient reactive oxygen species production, the efficient elimination of hydrophobic VOCs remains a challenge. This study evaluated the enhancement of aromatic hydrocarbon elimination from gas streams by adding H 2 O 2 or peroxymonosulfate (PMS) to ozone micro-nano bubbling (O 3 /MNB) technology. Results indicated that MNB increased the O 3 mass transfer coefficient (K L a) to 0.17 min −1 , 4.9 times that of conventional macrobubbling. Under an inlet load of (16 ± 0.8) g·m −3 ·h −1 and empty bed contact time (EBCT) of 45 s, adding H 2 O 2 or PMS markedly increased VOC removal. The O 3 /MNB/H 2 O 2 system achieved removal efficiencies of 86%, 83%, and 86% for benzene, toluene, and xylene, corresponding to elimination capacities of (13.76 ± 0.69), (13.28 ± 0.66), and (13.76 ± 0.62) g·m −3 ·h −1 , respectively. In the O 3 /MNB/PMS system, the removal efficiencies for these compounds were 91%, 80%, and 83%, with elimination capacities of (14.56 ± 0.73), (12.80 ± 0.64), and (13.28 ± 0.23) g·m −3 ·h −1 , respectively. Electron paramagnetic resonance (EPR), quenching tests, and probe experiments revealed that O 3 /MNB/H 2 O 2 system primarily utilized hydroxyl radicals (•OH) and singlet oxygen ( 1 O 2 ), whereas O 3 /MNB/PMS system employed •OH and sulfate radicals (SO 4 •- ). System optimization demonstrated that the O 3 /MNB/H 2 O 2 system showed optimal performance for moderate-to-low concentration waste streams under controlled pH, while the O 3 /MNB/PMS system exhibited superior adaptability for complex, high-concentration exhausts across broad pH ranges. This work provides a theoretical basis for industrial hydrophobic VOC treatment and insights into advanced low-temperature control technologies.

Alkali and alkaline-earth metals (AAEMs) are inherently present in biomass and exert pronounced influences during thermochemical conversion. However, the effects of different AAEM salt systems on the pyrolysis behavior and product distribution of individual biomass components remain insufficiently understood. In this work, the effects of representative AAEM salt systems based on different cations (K + , Na + , Ca 2+ , and Mg 2+ ) and potassium salts with different counter-anions (Cl - , CO 3 2- , HCO 3 - , SO 4 2- , PO 4 3- , and CH 3 COO - ) on the fast pyrolysis of cellulose, hemicellulose (xylan), and lignin were systematically investigated using thermogravimetric analysis coupled with detailed product characterization. The results demonstrate that AAEM salt composition strongly influences thermal decomposition behavior, product evolution, and carbon partitioning among char, bio-oil, and gas phases. Under chloride salt conditions, monovalent cations (K + and Na + ) generally promote depolymerization-related transformations and moderate formation of sugars or oxygenated compounds, whereas divalent cations (Ca 2+ and Mg 2+ ) induce distinct changes in ring-opening, dehydration, and furan-related product formation, likely associated with stronger interactions with oxygen-containing structures. Different potassium salt systems exhibit distinct product distributions, indicating that K + availability and counter-anion-associated chemistry, contribute to the observed pyrolysis behaviors. Phosphate- and sulfate-containing salts show stronger tendencies toward carbon retention, whereas acetate-, bicarbonate-, and carbonate-containing systems lead to different distributions of volatile oxygenates and hydrocarbons. In xylan pyrolysis, K 2 CO 3 - and KHCO 3 - -containing systems generate contrasting hydrocarbon and oxygenated product distributions, highlighting the influence of salt composition on intermediate transformation under intensified salt–biomass interactions. Overall, AAEM effects depend on metal species, counter-anion chemistry, biomass composition, and loading conditions. Lower AAEM concentrations favor stabilization of primary pyrolysis intermediates, whereas higher loadings promote secondary conversion processes that redistribute products among char, bio-oil, and gas phases. These findings provide mechanistic insights into the role of AAEM salts in biomass pyrolysis and offer guidance for tailoring product distributions toward renewable chemicals and carbon-rich materials.

The accurate determination of pharmaceuticals and personal care products (PPCPs) in wastewater is crucial for comprehensive environmental risk assessment and human exposure evaluation. Given the complex matrices of aqueous environmental samples, efficient sample preparation remains a critical challenge in analytical procedures. This study presents an ionic liquid-based aqueous two-phase system (IL-ATPS) extraction methodology used as a pretreatment step prior to high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) for the simultaneous determination of 38 PPCPs. A mechanistic investigation revealed that target analytes with more hydrogen-bonding sites and higher hydrogen-bond donor (HBD) capacity exhibited enhanced solubility in ILs. In addition, IL anions with stronger hydrogen-bond acceptor (HBA) capacity further improved the solubility of the 38 PPCPs. These findings indicate that hydrogen bonding between analytes and ILs likely played a critical role in the dissolution mechanism. The established IL-salt ATPS extraction method utilized a 15 mL aqueous sample, 0.2 g tetraethylammonium acetate ([N 2222 ][OAc]), and 12 g K 2 HPO 4 , with a 1-minute vortex mixing. Compared with traditional solid phase extraction (SPE), this approach significantly reduced the sample volume from 1 L to 15 mL, avoided the use of volatile organic solvents, simplified the overall processing, and enabled rapid (<15 minutes) pretreatment. The method demonstrated excellent sensitivity with limits of detection (LODs) ranging from 0.00013 to 0.11 ng/mL. Method validation via standard addition experiments demonstrated satisfactory accuracy, yielding recoveries between 74.3 and 129.8 %. Precision was assessed using both intra-day and inter-day measurements. The intra-day relative standard deviations (RSDs) ranged from 0.7 % to 19.9 %, while the inter-day RSDs ranged from 1.4 % to 18.4 %, demonstrating that the method provides consistent and reproducible results under controlled laboratory conditions. These findings underscore the present IL-based ATPS extraction method, followed by HPLC-MS/MS analysis, as an eco-friendly, robust, and scalable approach for PPCPs monitoring in aqueous environmental samples, offering potential applications in environmental monitoring and risk assessment.

Objectives The aim of this study is to evaluate the effectiveness of polyelectrolyte-cation complexes pre-precursor (PCCP) process using polymaleic acid (PMA) for inducing intrafibrillar mineralization, dentin remineralization and occlusion of dentinal tubules. Methods Collagen fibrils were successively treated with PMA-Ca suspension and phosphate solution, 5 min each, and incubated in artificial saliva for 2 days. Demineralized dentin of human dentin disks and rabbit’s incisors were treated as aforementioned, 20 min each, and followed by 2 days of incubation. They were identified by scanning/transmission electron microscopy (SEM/TEM) and high resolution TEM (HRTEM) with selected area electron diffraction (SAED). The mechanical properties of de- and remineralized dentin were evaluated by nanoindentation test. The dentin permeability testing of de- and remineralized dentin treated with different ways was conducted. The oral mucosa irritations of mineralization media were evaluated. Results The intrafibrillar mineralization and in vitro/in vivo remineralization of demineralized dentin were successfully achieved. The mechanical properties of remineralized dentin were recovered from demineralized dentin ( P < 0.001) close to natural dentin ( P > 0.05). The dentinal tubules were occluded exceeding 100 µm and dentin permeability was significantly decreased ( P < 0.001). No evident mucosa irritation was detected. Conclusions The PMA-Ca suspension following phosphate group could effectively induce in vitro/in vivo remineralization of demineralized dentin with in-depth occlusion of open dentin tubules and great reduction of dentin permeability. The effectiveness of PCCP process using PMA was validated. Clinical significance The PCCP process using PMA could be used for management of dentin caries and dentin hypersensitivity.

In the environment, chromium usually exists in both the trivalent and hexavalent states. Cr(VI) is of particular concern because it is highly toxic. However, it remains challenging to conduct field detection for trace concentrations of different valence states of Cr. Here, we propose a method based on laser-induced breakdown spectroscopy (LIBS) combined with an ion enrichment chip (IEC) to rapidly and sensitively detect the total Cr and Cr(VI) in water and soil. This method was termed IEC–LIBS. A chip with a millimetric channel was used for separating and enriching total Cr and Cr(VI) and LIBS was used for detection. The limits of detection (LoDs) of total Cr and Cr(VI) in water were 10 μg L−1 and 4 μg L−1, respectively, and the recoveries from spiked pool water ranged from 90 to 114%. The method also had good quantitative ability for soil detection, with total Cr and Cr(VI) LoDs of 13.6 mg kg−1 and 3.8 mg kg−1, respectively. The detection sensitivity of this method met the Cr environmental quality standards in China, and the detection time was within 20 min. IEC–LIBS is a simple and environmentally friendly method for detecting trace Cr in different valence states, and it is expected to be useful for field application.

To prevent the reactions of disinfection byproducts (DBPs) or natural organic matters with residual chlorine in drinking water in the course of the water store, residual chlorine is quenched by chlorine quenchers, while some chlorine quenchers may result in dechlorination of DBPs. Phenolic compounds are a group of highly toxic DBPs compared to regulated aliphatic DBPs (trihalomethanes (THMs) and haloacetic acids (HAAs)), which might be a great threat to drinking water safety. Nevertheless, impact of popular chlorine quenchers on phenolic DBPs is less understanding. In this study, the influences of ammonium chloride , ascorbic acid , sodium thiosulfate , and sodium sulfite on phenolic DBPs are assessed. Total concentration of 19 phenolic DBPs in drinking water from 7 Chinese cities was 145–1821 ng/L, suggesting a widely occurrence of these pollutants. Four assessed chlorine quenchers have not impacts on mass spectra of studied phenolic DBPs. Additionally, when the storage time ≤24 h, recoveries of 19 phenolic DBPs using four assessed chlorine quenchers are within the accept levels (70–130 %). However, when the storage time increased to 168 h, ascorbic acid and sodium thiosulfate satisfied the recovery requirement of phenolic DBPs during the sample analysis, and ammonium chloride and sodium sulfite showed a unacceptable impact on bromo-chloro-phenols. In general, ascorbic acid and sodium thiosulfate are recommended to be the ideal chlorine quenchers of phenolic DBPs. Mechanism study indicated that sodium sulfite induced the dechlorination of 2-chloro-4-bromophenol via nucleophilic reaction. This study is the first attempt to provide the impact of chlorine quenchers on phenolic DBPs and corresponding reaction mechanism.

Radiation-induced pulmonary fibrosis (RIPF) is a common adverse effect of thoracic radiation therapy. Although pirfenidone is approved for treating pulmonary fibrosis, its utility is limited by its short half-life and ability to scavenge reactive oxygen species (ROS). Thus, a nanoscale complexes of cerium(III), 10-carboxyl-pirfenidone, and 1,10-phenanthroline (NPs Ce(phen)Pirf 3 ) was developed to prevent RIPF in a mouse model. NPs Ce(phen)Pirf 3 was successfully prepared using a simple moderate solvothermal method and characterized using FTIR , electrospray ionization MS , 1H nuclear magnetic NMR, and transmission electron microscopy . The cerium(III) nanocomplexes exhibited a near-spherical shape and dissolved in water with a diameter of ∼125.2 nm , as characterized by dynamic light scattering . Compared with pirfenidone, NPs Ce(phen)Pirf 3 with blue fluorescence exhibited prolonged retention times with thoracic-specific accumulation in vivo. Mice received 15 Gy gamma-ray treatment on the thorax with or without NPs Ce(phen)Pirf 3 or pirfenidone administration. NPs Ce(phen)Pirf 3 improved lung function, alleviated radiation-induced pathological changes in the lung tissues, and reduced collagen deposition 16 weeks after radiation. Our results from in vivo and in vitro experiments demonstrated that NPs Ce(phen)Pirf 3 increased the ROS-scavenging ability. Additionally, NPs Ce(phen)Pirf 3 regulated epithelial-mesenchymal transition (EMT)-related proteins, including up-regulate E-cadherin and down-regulate N-cadherin, α-SMA, and TGF-β1 in RLE-6TN cells, which suggested NPs Ce(phen)Pirf 3 may alleviate RIPF by inhibiting EMT. Finally, NPs Ce(phen)Pirf 3 also inhibited the growth of thoracic tumor cells in mice. NPs Ce(phen)Pirf 3 had a protective role against RIPF and antitumor effects, suggesting that they are a promising therapy for thoracic radiation-induced RIPF.

Smart windows , which could save building energy consumption by modulating indoor thermal and light intensity, have attracted considerable attention in recent years. Photochromic (PC) and electrochromic (EC) are two representative working modes of smart windows. Integrating PC and EC on a single smart window is beneficial for adapting to various environments and meeting individual needs. However, it remains challenging to develop PC and EC dual-responsive materials. In this work, we reported two extended viologen derivatives, EV-1 and EV-2 , with both PC and EC properties. Photochromic devices (PCDs) and electrochromic devices (ECDs) based on these materials were fabricated successfully. Under UV light irradiation , the PCDs exhibited a significant color change from transparent to green ( PCD-1 ) and blue ( PCD-2 ) color, and the colored state can maintain a long time (2.73 h for PCD-1 and 41.72 h for PCD-2 ) after removing the UV light. Owing to the extension of the conjugate length of the chromophore as compared with traditional viologens using bipyridine as chromophores, the spectra response range of the devices was extended to the near-infrared (NIR) region. To obtain different light modulation capabilities, we fabricated electrochromic devices using propylene carbonate as solvent. These devices display different colored states (red for ECD-1 and purple for ECD-2 ) and spectra absorption compared to PCD-1 and PCD-2 . Furthermore, a photo/electrochromic device ( PECD ) smart window system was developed to enhance light and thermal regulation. This system offers four working modes, including off mode, photochromic mode, electrochromic mode, and photo-electrochromic mode, which opens up new possibilities for expanding its applications.

The synthesis of bio-based modified amphoteric epoxy modified acrylate sizing emulsion based on reversible addition fragmentation chain transfer (RAFT) polymerization and its application in paper sizing were studied. A macromolecular chain transfer agent for RAFT polymerization was synthesized by the esterification of epoxy resin E-51 with RAFT agent to eliminate the active groups on RAFT agent. Amphoteric polymer emulsifiers with good emulsification and dispersion effects in acidic and alkaline media were successfully prepared by RAFT polymerization. After neutralization, other monomers were polymerized to access cationic sizing emulsion (acid neutralization) and anionic sizing emulsion (alkali neutralization). The effects of bio-based monomer content, hydrophilic monomer dimethylaminoethyl methacrylate (DM) content and degree of quaternization on the properties of sizing emulsion and sizing paper were further explored. In addition to the particle size and polymer dispersion index (PDI) of latex particles in different experimental groups, the water resistance, folding resistance, bursting strength, tensile strength and surface roughness of sized paper were analyzed and evaluated. Based on these results, a better sizing emulsion formulation was established. It was confirmed that the addition of bio-based monomers can improve the sizing performance of paper.

Heterogeneous catalytic ozonation (HCO) is attractive for water decontamination and catalyst is a core element. However, it is difficult to maintain high efficiency and stability of catalysts under stern conditions. In this study, we proposed Mn-loaded C-SiO 2 -Framework (Mn-CSF) which contained stable silica core and robust carbon shell for efficient catalytic ozonation. The pseudo-first-order kinetic rate constant for oxalic acid removal of Mn-CSF catalytic ozonation was 160 % and 875 % higher than those of Mn-SiO 2 and pristine CSF, respectively. Mn-CSF was also proven effective in gasification wastewater treatment , where the COD was decreased to 46 mg·L −1 , 37 % lower than that of Mn-SiO 2 . These results indicated that the graphitization carbon layer and Mn significantly enhanced the activity of the catalyst. Furthermore, a fulvic-like component and a protein-like component were recognized through 3D-EEM in coal gasification wastewater. It was proven that Mn-CSF catalytic ozonation exhibited higher fulvic-like component and protein-like component removal compared with ozonation. Moreover, O 2 − and 1 O 2 were identified to be responsible for organic degradation in this research. Sufficient external specific surface area and porous structure were important for complex wastewater treatment. Specifically, external specific surface area could enhance the degradation of macromolecular organics while porous structures were vital for smaller molecular pollutant removal . The results highlighted that Mn-CSF was a promising HCO catalyst for advanced wastewater treatment, and this study provided evidence of relationship between structure of catalysts and HCO efficiency.

Organic solvent nanofiltration (OSN) membranes have a great application prospect in organic solvent separation, but the development of OSN membranes is mainly restricted by trade-off between permeability and rejection rate. In this work, a TA/Fe 3+ polymer was introduced into polyetherimide (PEI) ultrafiltration membranes crosslinked with hexamethylene diamine as the intermediate layer, and OSN membranes with high separation performance and solvent permeability were obtained through interfacial polymerization and solvent activation. The interlayer with high surface hydrophilicity and a fixed pore structure controlled the adsorption/diffusion of the amine monomer during interfacial polymerization, forming a smooth (average surface roughness < 5.5 nm), ultra-thin (separation layer thickness reduced from 150 to 16 nm) and dense surface structure polyamide (PA) layer. The PA- Fe 3 3 + -HDA/PEI membrane retained more than 94% of methyl blue (BS) in 0.1 g·L −1 BS ethanol solution at 0.6 MPa, and the ethanol permeation reached 28.56 L −1 ·m −2 ·h −1 . The average flux recovery ratio (FRR) of PA- Fe 3 3 + -HDA/PEI membrane was found to be 84%, which has better fouling resistance than PA-HDA/PEI membrane, and it was found to have better stability performance through different solvent immersion experiments and continuous operation in 0.1 g·L −1 BS ethanol solution. Compared with thin-film composite nanofiltration membranes, the PA- Fe 3 3 + -HDA/PEI membrane can be manufactured from an economical and environment-friendly method and overcomes the trade-off between permeability and rejection rate, showing great application potential in organic solvent separation systems.
