This study developed a green and integrated hydrothermal liquefaction process for efficiently converting cellulosic materials into ketone-based aviation fuel precursors. To address issues such as low hydrolysis efficiency and weak catalytic activity during biomass hydrothermal conversion, dielectric barrier discharge non-thermal plasma pretreatment was employed, combined with an Fe/NaHCO 3 synergistic catalytic system to regulate the reaction microenvironment and enhance product selectivity. First, plasma pretreatment utilizes high-energy electrons and active particles to disrupt the crystalline regions and hydrogen bonding network of cellulose, significantly reducing its crystallinity and exposing more reactive hydroxyl sites, thereby improving the hydrolysis and conversion efficiency of cellulose under hydrothermal conditions. Experimental results showed that after DNTP pretreatment at 12 kV for 15 min, the relative peak area of ketone products from cellulose increased by 28.2% compared to the untreated sample under hydrothermal conditions of 260 °C for 30 min. Furthermore, the introduction of NaHCO 3 together with Fe formed a synergistic catalytic system. The alkalinity of NaHCO 3 effectively neutralizes organic acids generated during liquefaction, eliminating H + poisoning of Fe active sites, while promoting the conversion of Fe into highly active Fe 3 O 4 and enhancing the Fe 3+ /Fe 2+ redox cycle. This suppresses intermediate condensation and coking, thereby improving the selectivity and carbon efficiency of ketone synthesis. Using holocellulose derived from rapeseed straw as feedstock, a ketone selectivity of 60.7% was achieved at an Fe-NaHCO 3 mixing ratio of 1:1. This process is characterized by its green nature, high efficiency, and ease of catalyst recovery, offering a promising technological pathway for the production of sustainable aviation fuels from biomass.

Corn germ meal contains high-quality protein with the potential of producing bioactive peptides. This study aimed to improve the peptide yield and bioactivity of protein hydrolysates from corn germ meal via thermal-alkaline treatment and solid-state fermentation. Corn germ meal was subjected to thermal-alkaline treatment, and the processing conditions were screened. The material obtained under the optimal conditions was then used for solid-state fermentation. The optimal conditions for thermal-alkaline treatment were 100 meshes, a treatment temperature of 100 °C, an alkali concentration of 1.3%, a treatment duration of 30 min, and a water addition of 120%. The protein digestibility of corn germ meal under optimal conditions improved by 86.28%. The combined treatment of thermal-alkaline treatment and solid-state fermentation significantly altered the chemical composition and structural characteristics of corn germ meal, thereby influencing the solubility and hydrolyzability of its proteins. This approach effectively increased the protein yield (≤37.89%) and peptide yield in protein hydrolysates (≤26.01%) of corn germ meal, consequently enhancing the antioxidant activity and angiotensin I-converting enzyme (ACE) inhibitory activity of protein hydrolysates. Furthermore, the treatment altered amino acid composition in the meal material and effectively degraded anti-nutritional factors such as phytic acid and tannin and improved the comprehensive utilization of corn germ meal.

Walnut kernels are highly susceptible to lipid oxidation because of their high content of unsaturated fatty acids. This study screened five lipid-soluble antioxidants—tert-butylhydroquinone (TBHQ), butylated hydroxytoluene (BHT), propyl gallate (PG), dilauryl thiodipropionate (DLTP), and ascorbyl palmitate (AP), and further evaluated binary and ternary formulations based on BHT. Treated walnut kernels were subjected to accelerated oxidation, and the oxidative stability was assessed using peroxide value, thiobarbituric acid-reactive substances (TBARS), DPPH radical scavenging activity, electron spin resonance, fatty acid composition, thermogravimetric analysis, and sensory evaluation. Among the individual antioxidants evaluated at their respective maximum permitted concentrations, BHT showed the most consistent protective effect, with the lowest oxidation indices, the strongest DPPH radical scavenging activity, and the weakest thermally induced radical signal. The BHT + TBHQ formulation performed significantly better than BHT alone in several oxidation indices (p< 0.05). The ternary BHT + TBHQ + DLTP formulation showed the best overall performance, with antioxidant activity comparable to that of the commercial antioxidant blend and significantly lower TBARS values than the BHT + TBHQ group (p< 0.05). Linoleic, oleic, and α-linolenic acids remained at 58.78–62.54%, 17.62–21.33%, and 10.64–11.31%, respectively. No significant differences in aroma or flavor were observed among treatments (p> 0.05). These findings indicate that BHT + TBHQ + DLTP effectively improves the oxidative stability of walnut kernels during accelerated storage.

Conversion-based metal sulfides/selenides anodes are promising for sodium-ion batteries (SIBs) owing to their high capacities and good electronic conductivity. However, their large volumetric variation during cycling often leads to rapid capacity decay, hindering commercial applications. Meanwhile, developing a low-cost and efficient synthesis strategy to enhance sodium storage remains challenging. Herein, defect engineering is introduced in bulk Fe 7 Se 8 (bulk-Fe 7 Se 8-x ) to fabricate a carbon-free and defect-rich anode. The optimized bulk-Fe 7 Se 8-x realizes remarkable fast-charging performance and good temperature adaptability, achieving excellent cyclic stability (384 mAh g −1 after 1300 cycles at 5 A g −1 and 25 °C, 170.6 mAh g −1 after 1000 cycles at 2 A g −1 and 0 °C, and 371.7 mAh g −1 after 500 cycles at 5 A g −1 and 40 °C) and ultrahigh rate capability (up to 40 A g −1 ), significantly surpassing reported Fe 7 Se 8 anodes. Reaction mechanism and reaction kinetics are elucidated through in/ex situ characterization, kinetics analysis, and DFT calculations. Furthermore, the exploration of full cells demonstrates their potential application of bulk-Fe 7 Se 8-x in SIBs. The universal strategy is also successfully applied to synthesize the high-performance, defect-rich bulk-Fe 7 S 8-x and bulk-CoSe 2-x , which provides an effective approach for other conversion-based anode materials.

Sulfurized zero-valent iron (SZVI) is a promising material for controlling soil/groundwater halogenated hydrocarbon pollution. However, systematic studies on how various physicochemical properties of soil affect SZVI dechlorination activity are still lacking. To explore the influence of solid and soluble components on SZVI activity, this study compared the dechlorination performance of SZVI on trichloroethylene (TCE) in three different soils across five systems: SZVI water (aqueous solution system), SZVI soil (soil system), SZVI pre-soil (pre-adsorbed TCE soil system), SZVI ex (soil extract system), and SZVI de-soil (soil system without soluble components). Additionally, the SZVI activity before and after aging in soil extract and solutions of various soluble components (within the concentration range of the soil extract) was compared, and the mechanism by which key soluble components influence the SZVI activity was explored. Results indicated that the dechlorination activity of SZVI was higher in soils compared to the performance in aqueous solution, and high soil organic matter content was the key inhibitor. The influence of soil solid-phase components on SZVI activity was significantly greater than that of soluble components. Soil particles enhanced SZVI activity by providing effective contact sites between SZVI and TCE, whereas soluble components inhibited SZVI activity by altering the physicochemical properties of its surface (e.g., NO 3 − and PO 4 3− ) and competing with TCE for electrons during the reaction (e.g., NO 3 − and Mn 2+ ). These findings offer new critical insights for selecting and optimizing materials based on soil physicochemical properties.

In the oil and gas industry, sulfonated drilling fluid, as a water-based drilling fluid, is applied on a large scale. The waste fluid mixed with drilling cuttings forms solid waste-sulfonated drilling waste (SW-SDM). Considering the water-soluble refractory organic matter in SW-SDM and the possible leaching of soil organic matter, processing SW-SDM to protect soil and groundwater from pollution is urgent. The present article systematically investigated the degradation of benzo[a]pyrene (BaP) in SW-SDM by iron (Fe) activated persulfate (PS) oxidation with special attention to revealing the influence of background Fe on degradation. The experimental results demonstrated that BaP in SW-SDM could be partly degraded by the activated PS oxidation system. Parameters such as the pH and dosages of PS and Fe may greatly influence the experimental results. A higher dosage of Fe inhibits degradation, whereas the addition of a small amount of Fe or even no Fe may facilitate the degradation of BaP. Naturally present Fe(II), Fe(III), and dissolved Fe from SW-SDM itself may activate PS for BaP degradation. The feasibility of the SW-SDM treatment was evaluated. Finally, the degradation intermediates of BaP by Fe and PS oxidation in soil were enriched by solid phase extraction and identified by gas chromatography-mass spectrometry to propose a transformed pathway.

Zero-valent iron (ZVI) is a promising material for the remediation of Cd-contaminated paddy soils. However, the effects of ZVI added during flooding or drainage processes on cadmium (Cd) retention remain unclear. Herein, Cd-contaminated paddy soil was incubated for 40 days of flooding and then for 15 days of drainage, and the underlying mechanisms of Cd immobilization coupled with Fe/S/N redox processes were investigated. The addition of ZVI to the flooding process was more conducive to Cd immobilization. Less potential available Cd was detected by adding ZVI before flooding, which may be due to the increase in paddy soil pH and newly formed secondary Fe minerals. Moreover, the reductive dissolution of Fe minerals promoted the release of soil colloids, thereby increasing significantly the surface sites and causing Cd immobilization. Additionally, the addition of ZVI before flooding played a vital role in Cd retention after soil drainage. In contrast, the addition of ZVI in the drainage phase was not conducive to Cd retention, which might be due to the rapid decrease in soil pH that inhibited Cd adsorption and further immobilization on soil surfaces. The findings of this study demonstrated that Cd availability in paddy soil was largely reduced by adding ZVI during the flooding period and provide a novel insight into the mechanisms of ZVI remediation in Cd-contaminated paddy soils.

The conventional Fenton process has the drawbacks of low efficiency of Fe 3+ /Fe 2+ conversion, low utilization of H 2 O 2 , and narrow range of pH. In this paper, molybdenum sulfide (MoS 2 ) was used as a co-catalyst to boost the nanoscale zero-valent iron (nZVI) based heterogeneous Fenton-like process for the degradation of Rhodamine B (RhB). The catalytic performance, influences of parameters, degradation mechanism, and toxicity of intermediates were explored. Compared with the conventional like-Fenton process, the existence of MoS 2 accelerated the decomposition of H 2 O 2 and the RhB degradation rate constant of MoS 2 /nZVI/H 2 O 2 reached more than six times that of nZVI/H 2 O 2 . In addition, the effective pH range of MoS 2 /nZVI/H 2 O 2 was broadened to 9.0 with 84.9% of RhB being removed within 15 min. The co-catalytic system of MoS 2 and nZVI was stable and had high reusability according to the results of four consecutive runs. Quenching tests and electron paramagnetic resonance (EPR) demonstrated that hydroxyl radical (·OH), superoxide anions (·O 2 − ), and singlet oxygen ( 1 O 2 ) were all involved in MoS 2 /nZVI/H 2 O 2 . Compared with nZVI/H 2 O 2 system, MoS 2 not only increased the corrosion of nZVI but also accelerated the conversion of Fe 3+ /Fe 2+ . ECOSAR analysis suggested that the overall acute and chronic toxicity of the degradation products decreased after treatment. Hence, this MoS 2 co-catalytic nZVI based Fenton-like process can be used as a promising alternative for the treatment of organic wastewater.

The in-situ reduction of zero-valent iron (ZVI) is an effective method for removing chlorinated aliphatic hydrocarbons (CAHs) from groundwater. The heterogeneity of environmental conditions is also crucial in affecting dechlorination efficiency. Until now, the effect of Sulfate (SO42–) on ZVI activity has been debated, and the related mechanism research on SO42– behaviour during the abiotic reduction process of chlorinated alkanes is still lacking. In this study, the impacts of SO42– concentrations (0, 2, 4, 8, 80 mM) on the degradation of 1,1,2-trichloroethane (1,1,2-TCA) by micron-size ZVI (mZVI) and nano-size ZVI (nZVI) were systematically investigated. For mZVI, Kobs increased by 0.6 (2 mM), 0.5 (4 mM), 1.1 (8 mM), and 1.6 times (80 mM). For nZVI, Kobs decreased by 32% (2 mM), 39% (4 mM), 45% (8 mM), and 9% (80 mM). The results showed that SO42– increased the rate of 1,1,2-TCA degradation by mZVI but weakened the reduction performance of nZVI; however, this inhibition was reduced when the concentration reached 80 mM. SO42− controlled the degradation of 1,1,2-TCA mainly through the formation of different iron-sulfate complexes on the ZVI surface: water-soluble bidentate iron-sulfate complexes formed on the mZVI surface promoted the corrosion of the oxide layer and accelerated the reduction of 1,1,2-TCA, monodentate complexes mainly formed on the nZVI surface inhibited the reduction of 1,1,2-TCA by blocking surface sites. These results demonstrate the proof of concept to assist land managers in the field application of ZVI technology for the remediation of CAHs contaminated sites with different background concentrations of SO42−.

Extensive studies have been carried out on phosphate removal by zero valent iron (ZVI). Different mechanisms of phosphate removal by ZVI such as phosphate adsorption and precipitation of ferric phosphate and vivianite (Fe 3 (PO 4 ) 2 ·8H 2 O) have been reported. In this study, attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), X-ray powder diffraction (XRD), and X-ray absorption near edge spectroscopy (XANES) were used to elucidate the mechanisms of phosphate removal by micron-scale zero-valent (mZVI). Time-series ATR-FTIR analysis revealed that phosphate was removed by ZVI in two steps: a) adsorption of phosphate in the first 3 days, and b) slow conversion of the adsorbed phosphate into the precipitated form in 6 days. XRD and XANES analysis determined that iron oxides, ferric ion, and ZVI with oxide layer inhibited the formation of vivianite, resulting in the formation of phosphate precipitates, such as H 2 Fe(II)P 2 O 7 . The results suggested that phosphate is removed by ZVI mainly through precipitation under aerobic conditions. The knowledge gained in this study improves the fundamental understanding of the phosphate removal processes via ZVI.

Diabetic cardiomyopathy is a primary myocardial injury induced by diabetes with complex pathogenesis. In this study, we identify disordered cardiac retinol metabolism in type 2 diabetic male mice and patients characterized by retinol overload, all-trans retinoic acid deficiency. By supplementing type 2 diabetic male mice with retinol or all-trans retinoic acid, we demonstrate that both cardiac retinol overload and all-trans retinoic acid deficiency promote diabetic cardiomyopathy. Mechanistically, by constructing cardiomyocyte-specific conditional retinol dehydrogenase 10-knockout male mice and overexpressing retinol dehydrogenase 10 in male type 2 diabetic mice via adeno-associated virus, we verify that the reduction in cardiac retinol dehydrogenase 10 is the initiating factor for cardiac retinol metabolism disorder and results in diabetic cardiomyopathy through lipotoxicity and ferroptosis. Therefore, we suggest that the reduction of cardiac retinol dehydrogenase 10 and its mediated disorder of cardiac retinol metabolism is a new mechanism underlying diabetic cardiomyopathy.

The density and viscosity of N-butylmorpholine bromide iron-based ionic liquids ( r FeCl 3 / [Nbmm]Br) with two iron-morpholine ratios ( r = 0.8 and 1.0) mol·mol −1 were measured at 303.15–348.15 K and 101.3 kPa. Density and viscosity data were fitted by empirical correlations for temperature. The average relative errors were less than 0.02 % and 2 %, respectively. The density and viscosity decrease with increasing temperature. The density increases with the increase of r , while the viscosity shows the opposite trend. The gas-liquid equilibrium data of H 2 S in r FeCl 3 /[Nbmm]Br were measured by the isochoric pressure drop method at temperatures of 303.15–348.15 K, pressures of 0–200 kPa, and r of 0.8 and 1.0 mol·mol −1 . The total solubility of H 2 S increases with decreasing temperature, increasing pressure, and decreasing r . The measured solubility data were fitted by the reaction equilibrium thermodynamic model. Chemical reaction equilibrium constant and the Henry's constant at different temperatures and different r were obtained. The average relative error of model fitting is less than 3 %. The results show that the chemical reaction equilibrium constant and the Henry’s constant both decrease with the increase of r , and decrease of temperature. Effect of molecular structure on reaction equilibrium constants was explained by quantum chemistry calculation. The absorption of H 2 S in r FeCl 3 / [Nbmm]Br at low pressure is dominated by chemical absorption. With the increase of pressure, the proportion of physical absorption continues to increase, and gradually occupies the main part.
