In response to the critical challenge of managing dye wastewater in the textile industry, this research presents an economically viable modification approach to enhance the dye/salt separation efficacy and operational stability of polyamide (PA) based nanofiltration membranes. By incorporating diethanolamine (DEA) as piperazine-aqueous phase additive and polyquaternium-10 (PQ-10) as surface modifier, this technique significantly optimized the properties of loose nanofiltration membranes. Structural modifications resulted in a significant reduction in surface zeta potential at pH 7.0, from −28.9 mV to −2.0 mV, expanded the molecular weight cut-off (MWCO) and most probable pore radius from 360 to 2340 Da and 0.28 to 0.64 nm, respectively. These changes led to high water permeability of 420.4 L·m −2 ·h −1 ·MPa −1 and much low sodium sulfate (Na 2 SO 4 ) rejection of 10.3 %, while maintaining a 98.9 % rejection for dye Congo red (CR). Long-term operational tests demonstrated stable rejection of approximately 98 % for CR and 11 % for Na 2 SO 4 over 50.0 h, affirming the high separation efficiency and good durability of membranes. This enhancement in dye/Na 2 SO 4 separation not only optimizes the balance between permeability and selectivity but also shows significant potential for scaling to industrial applications. The findings provide a robust strategy for addressing critical demands in wastewater treatment within the industry.

Synthesis of 5-ethoxymethylfurfural (EMF) from the etherification of 5-hydroxymethylfurfural (HMF) and the dehydrative etherification of fructose over K-10 clay supported dodecatungstophosphoric acid (abbreviated as K-10 clay-HPW). 30% wt.% K-10 clay-HPW was found to be the efficient and robust catalyst for the synthesis of EMF. The highest EMF yield of 91.5% was obtained from HMF after 10 h at 100 °C. Further more, the catalyst also showed high catalytic activity for the dehydrative etherification of fructose with EMF yield of 61.5%. The reaction work-up is very simple and the catalyst could be reused several times without the significant loss of its catalytic activity.

Using an immersion method, an organic methyltrimethoxysilane (MTMS) coating was prepared on the surface of aluminum alloys at room temperature. A more corrosion-resistant coating has been successfully developed by optimizing hydrolysis conditions, adding surfactant OP-10 and conducting maturation treatment. To characterize the solution, a conductivity meter, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and a particle size analyzer were utilized. As for the analysis of the surface properties of the samples, a series of methods such as X-ray photoelectron spectroscopy (XPS), attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), contact angle measurements, scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), and Tafel polarization analysis were adopted. The results showed that the synergistic effect of OP-10 and maturation treatment can significantly improve the corrosion resistance of the coating.

Cytochrome P450 2J2 (CYP2J2) enzyme attracts more attention because it not only metabolizes clinical drugs but also mediates the biotransformation of important endogenous substances and the regulation of physiologic function. Although CYP2J2 is very important, few animal models are available to study its function in vivo. In particular, a CYP2J gene knockout (KO) rat model for drug metabolism and pharmacokinetics is not available. In this report, the CRISPR/Cas9 technology was used to delete rat CYP2J3/10, the orthologous genes of CYP2J2 in humans. The CYP2J3/10 KO rats were viable and fertile and showed no off-target effect. Compared with wild-type (WT) rats, the mRNA and protein expression of CYP2J3/10 in liver, small intestine, and heart of KO rats were completely absent. At the same time, CYP2J4 mRNA expression and protein expression were significantly decreased in these tissues. Further in vitro and in vivo metabolic studies of astemizole, a typical substrate of CYP2J, indicated that CYP2J was functionally inactive in KO rats. The heart function indexes of WT and KO rats were also measured and compared. The myocardial enzymes, including creatine kinase–muscle brain type (CK-MB), creatine kinase (CK), and CK-MB/CK ratio, of KO rats increased by nearly 140%, 80%, and 60%, respectively. In conclusion, this study successfully developed a new CYP2J3/10 KO rat model, which is a useful tool to study the function of CYP2J in drug metabolism and cardiovascular disease.

Royal jelly as a functional food has great potential to promote human health. As a unique ingredient in royal jelly, 10-hydroxy-2-decenoic acid (10-HDA) is a vital criterion to evaluate the quality of royal jelly. Current approaches for 10-HDA detection mainly rely on high-performance liquid chromatographic (HPLC), but it requires large-scale equipment and skilled technicians that are costly and time-consuming. Herein, we report a colorimetric sensing strategy for 10-HDA detection based on Ag(I) and tetramethylbenzidine (TMB), a widely used chromogenic reagent. Ag(I) can oxidize TMB to generate oxidized TMB (oxTMB) showing a light-blue color. Due to the chelation with Ag (I), the introduction of 10-HDA can prevent the generation of oxTMB that results in a color fading and a decrease in absorbance. This colorimetric sensing strategy enables highly sensitive detection of 10-HDA with a linear range from 1 μM to 10 μM and a limit of detection of 0.13 μM. More importantly, this 10-HDA assay allows for a visual readout either by a smartphone or the naked eye with low cost, convenience, and rapid response that has been successfully applied for evaluating the quality of royal jelly in actual samples. The sensing strategy developed in this work provides a new colorimetric approach that holds great promise as a point-of-care platform for the food industry.

Aluminum-containing hydrocarbon fuels cannot fully release their energy due to the poor dispersion and easy agglomeration of aluminum nanoparticles (ANPs). To solve the issues, oleic acid (OA) was used to modify the surface of ANPs, and then Al@OA particles were incorporated into exo-tetrahydrodicyclopentadiene (JP-10) to form Al/JP-10 bi-phase system. Experimental and molecular simulation methods were used to analyze the stability, ignition, and combustion performance of the Al/JP-10 bi-phase system. The results show that at low temperatures, OA can improve the antioxidant and hydrophobic performance of Al@OA particles, which can effectively protect the ANPs from deep oxidation . At high temperatures, OA can accelerate the oxidative exothermic process of ANPs, and the Al@OA particles can shorten the ignition delay time of JP-10 droplets and intensify the combustion. Notably, when the ratio of Al and OA is 10:3 in the Al@OA particles, the Al/JP-10 droplet exhibits the shortest ignition delay.

10-Hydroxycamptothecin (HCPT) liposomes surface modified with stearyl glycyrrhetinate (SG) were prepared by the film dispersion method. Characterization of the liposomes, including drug release in vitro, pharmacokinetics and tissue distribution, was done. HCPT in plasma and tissues was determined by high-performance liquid chromatography (HPLC). Compared with the conventional HCPT-liposomes and commercially available hydroxycamptothecin injection (HCPT Inject), pharmacokinetic parameters indicated that SG-HCPT-liposomes had better bioavailability. Regarding tissue distribution, the concentration of HCPT loaded by SG modified liposomes in the liver was higher than other tissues and the risk to the kidney was lower than HCPT-liposomes and HCPT Inject. These results support the hypothesis that the HCPT-liposomes modified with SG show enhanced liver-targeting through the glycyrrhetinic acid (GA) receptor to be an efficient drug carrier, which may help to improve therapeutic methods for hepatic diseases in the future.

An imidazolium-based ionic liquid (IL) was employed and modified by sodium lignosulfonate (LnNa) to synthesize hierarchical ETS-10 zeolite with porous structure, morphology and surface properties effectively adjusted. The template and structure-directing effects of both IL and LnNa proved to be well maintained after modification. And more importantly, the unique molecular recognition of LnNa was preserved well, while the aggressiveness of LnNa implementing through interaction with other inorganic species can be efficiently suppressed. This led to the formation of hierarchical ETS-10 zeolite with not only high crystallinity and structure integrity but also enhanced catalytic performance in aqueous-phase biomass conversion. Thus, for guaiacol hydrodeoxygenation, a notable conversion (92.8%) and cyclohexane yield (89.7%) can be acquired. This remarkable catalytic reactivity should be owing to its distinguished analogous molecular recognition pattern, promoted crystallinity, modified morphology and porous structure, and what’s more, the strengthened acid property.

10-Hydroxycamptothecine (10-HCPT), a natural alkaloid, is widely used in clinical practice because of its significant anti-cancer activity and small toxic side effects. In this work, graphene nanosheets (GNs) were prepared by ultrasonic exfoliation of graphite using N -methylpyrrolidone (NMP) as the solvent. The prepared GNs were characterized using transmission electron microscopy and scanning electron microscopy, and then used to construct a novel sensing platform for 10-HCPT. The electrochemical behaviors of 10-HCPT on the glassy carbon electrode (GCE) and GNs modified GCE (GNs/GCE) were studied. Compared with bare GCE, the prepared GNs/GCE increased the oxidation signal of 10-HCPT significantly, owing to larger active area of GNs/GCE and thus higher accumulation efficiency of 10-HCPT. Utilizing the signal amplification strategy of GNs, a highly-sensitive electrochemical method was established for the detection of 10-HCPT. The linear range was from 10.0 to 250.0 μg L −1 , and the detection limit was 3.21 μg L −1 (8.81 nM). It was used to detect 10-HCPT in urine samples, and satisfactory results were obtained.

The Pt@FGS/JP-10 nanofluids (0.1 wt% for Pt) were successfully prepared by two consecutive steps: loading Pt nanoparticles on the functionalized graphene sheets (FGS) grafted octadecylamine (ODA) via wet chemical method, following by dispersing it in JP-10 hydrocarbon fuel. The characterization of the prepared Pt@FGS showed that the size of Pt nanoparticles is ca. 2.2 nm, which could be stably dispersed in JP-10 for 2 weeks without significant aggregation or sediment, and the thermal conductivity of 0.2 wt% Pt@FGS/JP-10 nanofluids increases by ca. 35.2% compared with that of pure JP-10. Catalytic cracking performances of Pt@FGS/JP-10 nanofluids were evaluated in a batch reactor heated by fluidized sand at 360–420 °C, and observed that the cracking rate of JP-10 (400 °C, 5 h) improves by 150% in presence of 0.5 wt% Pt@FGS with improved hydrogen selectivity. The possible reason may be attributed to the catalytic dehydrogenation of JP-10 over Pt nanoparticles and the carbon defects on FGS (ca. 71.0% improvement in cracking rate for FGS/JP-10 nanofluids). This work provides a promising method to synchronously improve the thermal conductivity and endothermic cracking rate of JP-10 as a coolant for advanced aircrafts through adding trace Pt@FGS.

On the basis of the method used by Reinsch and Solovyeva, the aluminum based MOF material CAU-10-H (CAU stand for Christian-Albrechts-University) was synthesized by multiplying the amount of aluminum sulfate octahydrate and isophthalic acid by 10 times. CAU-10-H (b) is obtained after washing. In order to improve the water vapor adsorption performance of pure CAU-10-H (b), lithium chloride (LiCl) solution was compounded with CAU-10-H (b) by impregnation method to obtain a composite adsorbent CAU-10-H (L) and its adsorption characteristics were studied. The results showed that the composite adsorbent showed good adsorption and desorption performance under test conditions. Among them, the equilibrium adsorption capacity of the composite adsorbent with 33.1% LiCl content is 0.5007 g/g after 30 cycles, which is about 1.675 times of the adsorption capacity of pure CAU-10-H (b) under the same conditions. This shows the potential of the composite adsorbent to be used in the air-water extraction system.

There remains a great challenge to develop a switchable and feasible membrane for integrate reversible separation of oil/water mixtures. Herein, a highly-quality CAU-10-H mesh membrane with switchable superwettability was fabricated via solvothermal synthesis for on-demand oil/water separation. The CAU-10-H membrane exhibited under-liquid dual superlyophobicity due to the hierarchical micro-/nanostructures constructed by interpenetrating CAU-10-H crystals grown on the mesh. Meanwhile, the secondary growth time affecting the wetting behavior of the membrane is studied. More importantly, the membrane can achieve both immiscible oil/water separation and emulsion separation with high separation flux and high efficiency (>99.9%). Moreover, the membrane shows an excellent anti-corrosive property in various harsh environment. The present development would provide novel insights into the rational fabrication of MOF-based membranes for on-demand oil/water separation.
