Rapid, highly sensitive detection of mustard gas is a critical requirement in public safety and national defense. However, achieving highly sensitive, ppb-level detection of mustard gas under low-power conditions remains a significant challenge. Focusing on the typical blister agent simulant 2-chloroethyl ethyl sulfide (2-CEES), a solvothermal method was employed combined with controlled thermal treatment to fabricate an ultrathin porous NiFe 2 O 4 /NiO nanosheets heterostructure sensor derived from an Fe-Ni-MOF in-situ grown on a ceramic tube in this study. This material possesses uniformly distributed intimate heterogeneous interface, a high specific surface area (95.8 m 2 ·g −1 ), and abundant surface active sites, thereby significantly enhancing its adsorption and catalytic oxidation capability toward 2-CEES. At a low operating temperature of 130 °C, the sensor demonstrates a high response of 41.5 toward 10 ppm 2-CEES, a rapid recovery capability of only 84 s, and a low detection limit of 20 ppb, along with excellent selectivity, humidity resistance, reproducibility, and long-term stability. Through systematic characterization including XPS, in-situ DRIFTS, TPD, and DFT calculations, the multi-step catalytic oxidation pathway of 2-CEES on the composite surface is elucidated, along with the mechanism by which the heterostructure enhances gas-sensing performance via band structure modulation, interfacial charge transfer, and the built-in electric field. This study offers both new materials and novel insights for the development of low-power, highly sensitive sensors for trace detection of chemical warfare agents.

Effective oral delivery of natural products is essential for sustained therapeutic effects for type 2 diabetes mellitus (T2DM) therapy. However, compromised bioavailability leads to undesirable effect and hypoglycemia. Herein, biomimetic nanoplatform based on mesoporous polydopamine (MPDA) and inulin gel were designed to enhance the oral delivery of 1-Deoxynojirimycin (DNJ). DNJ was adsorbed via mesopores and hydrogen bonding by MPDA and encapsulated within the inulin hydrogel. The MPDA@Inulin gel exhibited sustained-release properties that allowed DNJ to be released persistently in the small intestine, thereby enhancing its oral bioavailability. Moreover, the capacity of DNJ@MPDA@Inulin gel in controlling the blood glucose levels was evaluated in a high-fat diet induced T2DM model. Notably, after 4 weeks of daily oral administration, DNJ@MPDA@Inulin demonstrated enhanced efficacy in controlling blood glucose levels in T2DM model mice, improving insulin sensitivity. More important, this hydrogel nano-sustained release platform based DNJ delivery system could ameliorate glucolipid metabolism, enhance intestinal mucosal barrier and reshape gut microbial composition. Thus, it is anticipated that inulin-MPDA based oral delivery system have a potential for natural products delivery to improve bioavailability and alleviate T2DM.

The poor sinterability and intrinsically positive τ f of BaZr(PO 4 ) 2 ceramics were addressed by introducing ZnO as a sintering aid and property modifier. In a conventional solid-state reaction route, ZnO promoted liquid-phase sintering through the in situ formation of BaZn 2 (PO 4 ) 2 , enabling near-full densification (>99% relative density) at 1250 °C. The ZnO content strongly affected phase evolution, microstructure, and microwave dielectric properties. The Q × f value reached a maximum at ∼4 wt% ZnO and then decreased because of losses associated with the secondary phase and increased grain-boundary density. Notably, τ f could be systematically tuned from positive to negative values through compensation by the negative- τ f BaZn 2 (PO 4 ) 2 phase. The optimized composition (4 wt% ZnO) exhibited ε r ≈ 10.1, Q × f ≈ 36,300 GHz, and τ f ≈ +0.4 ppm/°C. These results identify a promising microwave dielectric material that can be densified at a lower temperature and establish a practical strategy for tailoring τ f in phosphate ceramics through controlled secondary-phase formation.

MOF-based nanozymes are promising for colorimetric biosensing but are often limited by rigid coordination environments and poor active-site accessibility. Here, a 2-methylimidazole-regulated MIL-88B(Fe) nanozyme (2-MIM@MIL-88B) was prepared via an in situ coordination-competition strategy. Compared with pristine MIL-88B(Fe), 2-MIM@MIL-88B retained a spindle-like morphology but showed reduced crystallinity, nitrogen-containing species, pore-texture reorganization, and local Fe-site electronic modulation with increased defect-related centers. These changes correlated with enhanced peroxidase-like activity in the TMB-H 2 O 2 system, despite a reduced BET surface area. In a glucose oxidase-coupled colorimetric assay, 2-MIM@MIL-88B enabled glucose detection over 0.015–0.5 mM with a detection limit of 1.7 µM.

Unlike neutral aqueous batteries with cationic Zn 2+ as the charge carrier, alkaline batteries with anionic [Zn(OH) 4 ] 2‒ and OH ‒ are actually commercially feasible and thermodynamically stable thanks to their ability to suppress hydrogen evolution. Whereas commercial separators in alkaline batteries, without ion regulation capability, fail to suppress severe dendrite and passivation of anionic [Zn(OH) 4 ] 2‒ and accelerate ion transport of anionic OH ‒ . Herein, we tailor the coordination structures of alkali-stable cationic complexes in polymer separators (CCPS) to construct anionic OH ‒ selective transfer channels. Synchrotron spectroscopic characterizations and theoretical calculations reveal that the low-coordination cationic complexes expose more positive charge density, electrostatically attracting more negative charge from [Zn(OH) 4 ] 2‒ . In situ electrochemical digital holography technology and time-of-flight secondary ion mass spectrometry analyses further confirm the homogeneous [Zn(OH) 4 ] 2‒ distribution at the CCPS-electrode interface, oriented Zn deposition, and impeded passivation. As a result, CCPS enables alkaline Zn||Cu cells to operate over 5500 cycles at 1 mA cm ‒2 with a high coulombic efficiency of 99.99%. Alkaline Ni–Zn batteries exhibit ultrastable cycling over 1000 cycles at 6 C and maintain 86.17% of their maximum capacity at 10 C. Our work may provide practical and effective separator strategies to accelerate the commercialization of alkaline batteries.

Hydrogen is regarded as a promising alternative to fossil fuels; however, approximately 95% of the global hydrogen supply still comes from “gray hydrogen”, with high carbon emissions. Efficient separation of CO2 and H2 is a key challenge in gray hydrogen production. This study proposes a novel H2 recovery process based on an aqueous solution of 2-methylimidazole (2-MeIm). The 2-MeIm aqueous solution possesses both strong CO2 absorption capacity and easy desorption performance, which can reduce energy consumption. Pure component solubility experiments were carried out at temperatures ranging from 283.15 to 353.15 K and pressures ranging from 0 to 2.0 MPa, yielding 66 sets of pure CO2 solubility data and 15 sets of pure H2 solubility data, which were used to regress the binary interaction parameters of the NRTL model. Comparison between the fitted NRTL model parameters and the experimental data indicates that the mean relative error of CO2 is 5.19%, whereas that of H2 is only 0.18%. Further, single-equilibrium-stage phase equilibrium experiments were conducted using a mixed gas stream with a CO2/H2 molar ratio of 40:60 to further validate the accuracy of the fitted NRTL parameters. The results demonstrate that the solubility-based fitted model achieves a mean absolute error (MAE) of 0.03 for gaseous CO2 and a mean relative error (MRE) of 0.93% for liquid-phase CO2, indicating high predictive accuracy. Based on Aspen Plus, this study has developed a rigorous process simulation model with a processing capacity of 100,000 N m3/h. The operating conditions were defined through sensitivity analysis, resulting in the following optimized parameters: 7 theoretical stages for the absorber, an operating pressure of 3.8 MPa, a volumetric gas-to-liquid ratio of 200, and a desorption temperature of 373.15 K. Under these conditions, H2 purity and recovery reached 99.99% and 99.13%, with specific energy consumption of only 260.27 kgoe/t H2 (10.88GJ/t H2). Compared with the conventional Rectisol process, the 2-MeIm-based process not only achieves higher H2 purity and recovery rate, but also significantly reduces total energy consumption by 32.07%. This marked performance enhancement underscores the outstanding energy-saving potential of the 2-MeIm system in the field of H2/CO2 separation.

Developing highly efficient organic corrosion inhibitors plays a crucial role in enhancing copper's resistance to degradation in aggressive environments. This research evaluates the corrosion inhibition efficacy of 2-aminothiophene-3-carboxamide (2ATCA) at the copper interface in simulated seawater medium (3.5 wt% NaCl). The findings indicate that incorporating 0.60 g/L of 2ATCA into the NaCl solution leads to a significant drop in corrosion current density, from 12.1 μA·cm -2 to 1.7 μA·cm -2 , achieving an inhibition efficiency of 86%. The Langmuir adsorption isotherm model was derived by applying the thermodynamic principles governing the corrosion inhibitor's mechanism. The surface characteristics and composition of copper were characterized through a combination of analytical techniques including scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS). The adsorption inhibition mechanism and reactivity of 2ATCA on the copper surface were further investigated through theoretical computational analysis. This study not only elucidates the adsorption behavior and mechanism of 2ATCA on copper but also provides a foundation for designing more effective organic inhibitors for copper corrosion in marine environments.

Vitamin D deficiency (VDD) is common in type 2 diabetes mellitus (T2DM) and has been linked to dyslipidemia, but the specific lipids associated with low vitamin D status are not well defined. To address this, we sought to characterize lipidomic alterations associated with VDD in T2DM and describe the changes following vitamin D₂ (VD2) supplementation. Specifically, untargeted serum lipidomics with anthropometric and clinical measurements were performed in 219 adults with T2DM, classified as VDD (25(OH)D < 20 ng/mL; n = 138) or non-VDD (25(OH)D ≥ 20 ng/mL; n = 81). A subset of VDD participants (n = 20) completed a 3-month VD2 supplementation trial. Lipids were profiled by UHPLC-HRMS and analyzed in relation to metabolic and anthropometric measures. Our analysis identified 112 lipid species differentially expressed in VDD, characterized by reduced ether-linked phosphatidylcholines (EtherPCs) and elevated ceramide 16:0. EtherPCs showed negative correlation with HbA1c, BMI, as well as body fat, and positive associations with muscle mass and bone mineral content, whereas ceramides inversely associated with these metabolic indices. Following 3-month VD2 supplementation, increases in circulating 25(OH)D and reductions in HbA1c were observed, accompanied by changes on the targeted lipidome, including elevated EtherPCs and reduced ceramide profiles (Cer 20:0, Cer 22:0, Cer 16:0/24:0). In conclusion, VDD in T2DM is associated with a distinct lipidomic profile marked by EtherPCs depletion and ceramide accumulation. The observed lipidomic changes following VD2 supplementation suggest the presence of a VD2-responsive lipid signature, which may have potential implications for metabolic risk management in T2DM.

Chemodynamic therapy (CDT) generates cytotoxic hydroxyl radicals (•OH) in tumors via Fenton/Fenton-like reactions using elevated H₂O₂ and acidity. However, its clinical potential is limited by poor tumor selectivity and the difficulty in balancing catalytic metal ion doses with toxicity. In this work, using HPBio (2-Pyridinecarboxaldehyde biotin bis-hydrazide) as the ligand, a biotinylated tri-nuclear copper(II) complex of POBio-Cu 3 has been in-situ synthesized. The solution assemble behavior and in-situ oxidation process has been investigated by time-dependent ESI-MS technology. In the atomically precise POBio-Cu 3 , biotin moiety was acting as a cancer-targeting unit and multi-nuclear Cu(II) core as a GSH depletor for augmented CDT effect. POBio-Cu 3 could preferentially accumulate in cancerous Hep-G2 cells, due to the cell discrepancy toward normal WI38 cells. The Cu(II) centers in POBio-Cu 3 were available for consuming glutathione (GSH) and amplifying oxidative stress. Furthermore, the results of in vivo experiments showed that POBio-Cu 3 could remarkably inhibit tumor growth without significant damage to major organs.

This study presents the synthesis of novel Mg(BH 4 ) 2 @V 2 C, Mg(BH 4 ) 2 @Nb 2 C and Mg(BH 4 ) 2 @Ti 3 C 2 composites using a solution-based nanoconfinement strategy, achieving robust architecture of Mg(BH 4 ) 2 onto Mxene structures. Among these composites, the Mg(BH 4 ) 2 @V 2 C composite exhibited an initial dehydrogenation temperature of 76.4 °C and released 9 wt% hydrogen at 300 °C, which exhibited the optimal hydrogen release behavior. Its two-step dehydrogenation activation energies (104.44 kJ/mol and 118.52 kJ/mol) were significantly lower than those of pure Mg(BH 4 ) 2 , showing improved dehydrogenation kinetics. After four absorption-desorption cycles, the composite could still desorb 4.9 wt% hydrogen, demonstrating excellent cycling stability. Further structural investigations revealed that V 2 C actually acted as a “functionalized” matrix, which improved hydrogen storage through a combination of nanoconfinement and catalytic effects, promoting both hydrogen desorption and absorption. This work provides critical insights for designing high-performance hydrogen storage materials and advances the development of next-generation storage systems.

Electrooxidation offers a sustainable alternative by utilizing renewable energy to convert biomass-derived cyclohexanol (CHA) to adipic acid (AA), a key industrial chemical for nylon-66 and polyurethane production. While bimetallic Ni-based catalysts enhance the conversion, the role of secondary metals in modulating Ni active-site reconstruction during operation remains unclear, limiting performance optimization. Here, we demonstrate that Cr-doping promoted the dynamic reconstruction of Ni(OH)2 nanosheets to form NiOOH with abundant Ni3+ and oxygen vacancies (OVs), significantly boosting AA electrosynthesis. In situ characterizations reveal that Cr-doping accelerates OH– adsorption and promotes NiOOH formation, while subsequent Cr3+ leaching generates OVs, thus, resolving the long-standing dilemma between stabilizing high-valence Ni and maintaining abundant defects. The optimized catalyst achieves 78.1% AA yield and 85.4% Faradaic efficiency at 1.45 V vs RHE, outperforming undoped Ni(OH)2 and prior systems. Mechanistic studies identify surface Ni3+ and OVs-stabilized *OOH species as the keys for CHA dehydrogenation and cyclohexanone oxidation, respectively. Moreover, a membrane electrode assembly electrolyzer was designed for the efficient coproduction of AA (0.078 mmol h–1 cm–2) and H2 (42.9 mL h–1 cm–2) at a current density of 100 mA cm–2, demonstrating the scalability. This work clarifies the in situ reconstruction of bimetallic sites and provides a design strategy for the efficient electrosynthesis.

Di(2-ethylhexyl) phthalate (DEHP) is a widespread plasticizer and environmental contaminant. In this study, a highly efficient DEHP-degrading consortium, LCF, was enriched using DEHP as the sole carbon source. LCF achieved >92% DEHP removal within 48 h over a wide concentration range of 50–2000 mg/L, and the degradation followed first-order kinetics with half-lives of 7.63 –12.70 h. LCF maintained high activity under diverse environmental conditions (25–40°C, pH 7–10) and degraded multiple phthalate esters and key intermediates. Further, the corn straw biochar-immobilized microbial agent CSC-LCF improved DEHP removal in simulated wastewater by 33% over the free consortium, likely through coupled adsorption, sustained release, and biodegradation. Community analysis showed that LCF was dominated by Gordonia , Variovorax , and Rhodococcus . Combined with functional prediction and intermediate degradation results, a putative degradation pathway involving ester hydrolysis, aromatic intermediate transformation, and ring-cleavage metabolism was proposed. This study provides a valuable microbial resource and application reference for the bioremediation of phthalate-contaminated environments.
