With the rapid advancement of digital inkjet printing technology, considerable attention has been directed toward the formulation design of inks. In this research, a comprehensive investigation was conducted into the physicochemical properties of reactive dye inks formulated with C.I. Reactive Blue 194. An orthogonal experimental design approach was utilized to optimize the proportions of the various solvents, resulting in the preparation of a reactive dye ink exhibiting exceptional performance. The ink possessed outstanding thermal stability, freeze–thaw stability, and robust centrifugal stability. Additionally, the ink's drying performance was verified; after 185 h of drying, the weight retention rate was 48%, while maintaining good wetting ability. Fabrics printed with this ink demonstrated high-quality results following steaming at 100°C and 100% relative humidity for 10 min. The rubbing and soaping fastness ratings of the printed fabrics were both in the range of grade 4–5, demonstrating excellent color fastness. Moreover, the variation rates of printed line width in the warp and weft directions were 12.05% and 18.79%, respectively, indicating clear pattern definition on cotton fabrics. This study offers strong support for the technological progression and industrial deployment of digital inkjet printing for high-quality textile printing.

A Whole-cell method co-displaying ACT and PPK2 enables low-cost butyrolactam biosynthesis. • Co-display of ACT and PPK2 increases butyrolactam productivity by 46.4% against ACT display alone. • Fed-batch fermentation achieves 39.13 g/L butyrolactam with 94.7% yield, showing industrial potential. Butyrolactam is a high value-added monomer and an important intermediate for various physiologically active substances, and has been widely used in the pharmaceutical, pesticide, and chemical industries. Though the biosynthesis of butyrolactam is gradually advancing, challenges such as the requirement for expensive cofactor adenosine triphosphate (ATP) and the barrier of substrate transmembrane transport in whole-cell synthesis hinder its large-scale industrial application. In this study, an integrated whole-cell catalytic strategy combining ice nucleation protein (INP)-mediated surface display and ATP regeneration was developed. Compared with the butyrolactam productivity of cells intracellularly expressing β-alanine CoA transferase (ACT), co-expressing polyphosphate kinase 2 (PPK2) to regenerate ATP and display ACT on the cell surface only increased it by 23.1% and 25.0%, respectively. Co-displaying ACT and PPK2 further increased the butyrolactam productivity, which was 46.4% more than that of only ACT displayed cells. Using fed-batch fermentation strategy, a final butyrolactam titer of 39.13 g/L and a yield of 94.7% were achieved in the strain co-displaying ACT and PPK2. Our findings demonstrate a potentially attractive strategy for the industrial butyrolactam production.

Qingke(highland barley) is a unique Tibetan Plateau crop, vital for local diets and traditional products. However, flavor differences among its varieties remain unclear. This work examined 4 representative Qingke varieties to investigate their flavor profiles and key aroma contributors. 60 aroma compounds were identified in the 4 Qingke varieties using gas chromatography–mass spectrometry and aroma extract dilution analysis. The results revealed that black/white and blue/yellow Qingke had similar flavor profiles respectively. Besides, black and white Qingke possessed more intense and abundant aromas, with 81 and 77 compounds, respectively. These two varieties were selected for further flavor analysis by aroma recombination experiment, which identified ( E )-2-octenal, vanillin, γ -caprolactone, 3-methylthiopropanal and 4-vinylguaiacol as key odorants. Additionally, 1-pentanol, 3-hydroxy-2-butanone, phenylethanol and guaiacol were found to be the flavor differentiators of black and white Qingke using omission experiment. This work provides a scientific foundation for Qingke's flavor quality assessment, product development and future applications.

The nanosheet MFI zeolite synthesized with a short b-axis length exhibits broad potential for industrial applications due to its ability to facilitate mass transfer through the large straight-through channel along the b-axis. The current focus of research lies in the regulation of the zeolite crystal anisotropic growth rate through the addition of specific additives to the precursor liquid. The range of available additives, however, is limited, and their effects as well as potential mechanisms are still poorly understood. The impact of incorporating ten mononitrogen compounds into the gel on crystal growth was investigated. The influence of the N-containing compounds (functional group, C/N ratio, electrostatic potential of N atoms, and compound concentration) and growth time on crystal size was analyzed. N,N-dimethylformamide (DMF) and N-methylformamide (NMF) were revealed as potential inducers of the nanosheet zeolite. Herein, the effect of DMF on the nonclassical growth of the nanosheet zeolite is unveiled within crystallization engineering. The effects of various synthetic parameters on the DMF-assisted synthesis of nanosheet zeolites were also investigated. It is revealed that DMF plays a role in accelerating crystal growth and in regulating anisotropic crystal growth. This strategy can be extended to the synthesis of different heteroatomic nanosheet zeolites (such as Al-MFI, Fe-MFI, and Ti-MFI), and it is suitable for different types of silicon and metal sources. This study presents a straightforward strategy for the systematic and precise design and synthesis of nanosheet MFI zeolites, which exhibits significant potential for industrial utilization.

A facile, ultra-sensitive and cost-effective electrochemical sensor was successfully prepared by combining metal–organic framework ZIF-8 with MWCNTs-COOH, which detecting of tert -butylhydroquinone (TBHQ) in edible oil and fried foods. The hydrothermally synthesized ZIF-8 material with microporous structure was demonstrated to have large specific surface area, and together with the MWCNTs-COOH with high electrical conductivity and catalytic properties, was used as a modified substrate for electrodes. Because of the synergistic effect between ZIF-8 and MWCNTs-COOH, the modified electrode exhibited significant electrocatalytic ability for TBHQ. Under the optimal experimental conditions, the ZIF-8/MWCNTs-COOH modified electrode obtained good linearity when the TBHQ concentration ranged from 0.01 to 25.0 μg mL −1 with the LOD (limit of detection) of 0.009 μg mL −1 (S/N = 3). Moreover, the constructed electrochemical sensor exhibits better anti-interference capability, reproducibility and stability, and can be used to monitor the content of TBHQ in oil and fried foods.

The effects of N-methyl pyrrolidone hydrogen sulfate ([Hnmp]HSO 4 ), α-pyrrolidone hydrogen sulfate ([Hnhp]HSO 4 ), and dinucleated pyrrolidone hydrogen sulfate ([[Hnhp]HSO 4 ] 2 ) on ring-opening of epoxidized soybean oils (ESO) was comparatively investigated. Results showed that [Hnhp]HSO 4 had stronger catalytic activity than the other two. Under the optimal conditions ([Hnhp]HSO 4 loading of 6%, water-epoxy group ratio of 9:1 (mol/mol), reaction temperature of 45 °C, and reaction time of 4 h), the resulting di-hydroxylated soybean oils (DSO) with an epoxy content of 0.87% and hydroxyl value (OHV) of 213.41 mg KOH/g was achieved, which corresponded to a conversion rate of OHV of 57.98%. In-situ Fourier transform infrared spectroscopy (In-situ FTIR) and FTIR analyses indicated that the rapid ring-opening of ESO and formation of DSO mainly occurred at 2–3.5 h. The increase of polarity and molecular weight after ring-opening and the formation of hydrogen bonds resulted in the higher viscosity of DSO than ESO. ESO and DSO were thermally stable at up to 350 °C. The effectiveness of [Hnhp]HSO 4 in catalyzing the ring-opening of ESO was comparable to that of inorganic acids. Almost complete ring-opening of epoxy groups with much less etherification leads biopolyols to have more available hydroxyl groups. Thus, the resulting biopolyols can be processed as chemical intermediates under more flexible parameter conditions.

Carbon capture, utilization, and storage (CCUS) are among the key technologies to achieve large-scale carbon emission reduction globally. Amino acid ionic liquids (AAILs) featuring biodegradability and biological activity are capable as eco-friendly absorbents for CO 2 capture. Herein, a series of novel AAILs are proposed via one-step hydrolysis of cheap lactams, which can act as messengers to facilitate aqueous solution of multi-tertiary-amines fast and pronounced absorption of CO 2 . Dynamic absorption experiments were carried out to indicate that [N 1111 ][Maba]-PMDETA-50 % showed a larger apparent absorption rate constant (0.282 min −1 ) than that of MDEA solution (0.043 min −1 ), demonstrating the activated role of AAILs. [N 1111 ][Maba]-PMDETA-50 % shows the exceptional absorption capacity of 0.162 g (1.0 bar) or 0.095 g (0.1 bar) of CO 2 per g absorbent at 313.2 K, respectively, surpassing all the reported formulated solution. The facilitated absorption mechanism is also illuminated from the NMR spectra. The regeneration heat (equal to absorption enthalpy) was calculated to be − 55.7 kJ·mol −1 from absorption isotherm of three different temperatures. The recyclability was evaluated from the vacuum regeneration (ten consecutive absorption–desorption cycles) and dynamic thermal regeneration, achieving the regeneration efficiency of more than 95 % and 99 %, respectively. All these experimental data indicate that the AAIL-based multi-tertiary-amines aqueous solution may be good candidate absorbent in terms of rapid efficient capture of CO 2 .

This article proposes for the first time the preparation of a series of amino acid ionic liquids (AAILs) via one-step hydrolysis of cheap lactams for the capture of CO 2 . The structures of the prepared AAILs are confirmed using NMR, FTIR, and ESI-MS, and their physical properties are also determined. It is found that these AAILs are reversible CO 2 absorbents with very high absorption capacities (0.15 to 0.18 g·g −1 at 313.2 K and 1.0 bar), better than almost all task-specific ionic liquids reported in literatures. The absorption mechanism is also elucidated to be a combination of 1:1 and 2:1 stoichiometric reaction of AAILs with CO 2 from NMR, FTIR, reaction equilibrium thermodynamical modeling and quantum calculations. The AAILs have the advantages of simple synthesis, high yield, and using available cheap raw materials. It is believed that this kind of AAILs have great potentials to be used as efficient CO 2 absorbents.

Gas-quenching fabrication of perovskite films demonstrates promising compatibility for commercialization of perovskite photovoltaics . Seeking suitable ligand for the perovskite precursor inks to improve the crystalline quality of gas-quenched methylammonium free perovskite films is critical for realizing up-scalable fabrication of stable perovskite solar cells . In this work, a series of pyrrolidone-based ligands are employed in gas-quenching fabrication of FA 0.9 Cs 0.1 PbI 3 perovskite films. Optical and morphological characterizations indicate 2-pyrrolidone is the most preferred ligand to deliver a neat buried-interface as well as a light-trapping surface at the rear of the device, which maximized the light-harvesting and the photocurrent of the device. The corresponding device achieved a power conversion efficiency of 21.6% without any interfacial passivation, as well as reduced defect density from their electrical characteristics . Moreover, a more stable performance of the device is obtained with 2-pyrrolidone compared to other pyrrolidone-based ligands, demonstrating 2-pyrrolidone as a promising ligand in designing the perovskite inks for methylammonium-free perovskite solar cells .

The objective of this research was to modify the crystal shape and size of poorly water-soluble drug ropivacaine, and to reveal the effects of polymeric additive and ultrasound on crystal nucleation and growth. Ropivacaine often grow as needle-like crystals extended along the a -axis and the shape was hardly controllable by altering solvent types and operating conditions for the crystallization process. We found that ropivacaine crystallized as block-like crystals when polyvinylpyrrolidone (PVP) was used. The control over crystal morphology by the additive was related to crystallization temperature, solute concentration, additive concentration, and molecular weight. SEM and AFM analyses were performed providing insights into crystal growth pattern and cavities on the surface induced by the polymeric additive. In ultrasound-assisted crystallization, the impacts of ultrasonic time, ultrasonic power, and additive concentration were investigated. The particles precipitated at extended ultrasonic time exhibited plate-like crystals with shorter aspect ratio. Combined use of polymeric additive and ultrasound led to rice-shaped crystals, which the average particle size was further decreased. The induction time measurement and single crystal growth experiments were carried out. The results suggested that PVP worked as strong nucleation and growth inhibitor. Molecular dynamics simulation was performed to explore the action mechanism of the polymer. The interaction energies between PVP and crystal faces were calculated, and mobility of the additive with different chain length in crystal-solution system was evaluated by mean square displacement. Based on the study, a possible mechanism for the morphological evolution of ropivacaine crystals assisted by PVP and ultrasound was proposed.

Developing absorbents with highly efficient nitric oxide (NO) absorption and desorption is very important for flue gas denitrification process. Toward this end, a class of DBU-based deep eutectic solvents (DESs) containing alkanones or azoles as functional HBDs for the capture of NO were synthesized in this work, with viscosities of only 7.71–45.57 mPa·s at 303.2 K. Solubilities of NO in these DESs were determined at temperatures from 303.2 to 333.2 K and pressures from zero to 1 bar. It was found that the absorbing abilities of the DESs increased with the increasing HBDs’ alkalinity. Impressively, these DBU-based DESs had remarkable larger absorption capacities than those reported DESs in the literature. According to the solubility curves of NO, chemical absorption was thought to occur accompanying with the physical one in the systems. Therefore, the reaction equilibrium thermodynamic model (RETM) was applied to model the experimental NO solubilities. The corresponding thermodynamic parameters for each system, such as the reaction equilibrium constant, Henry’s law constant, and the enthalpy change were also obtained to assess the NO absorption process in these DESs.

There is a demand for simple, selective, and efficient assays for the determination of clinically important metabolites such as creatinine for healthcare. Creatinine is the by-product of muscle energy metabolism and is excreted by the kidneys. To measure creatinine in the human serum, a creatinine imprinted photonic crystal hydrogel (CIPC hydrogel) for naked-eye detection is developed. CIPC hydrogel utilizes polystyrene-based two-dimensional (2D) photonic crystal colloidal arrays (PCs-array) embedded in the polyacrylamide hydrogel containing methacrylic acid which imprinted the creatinine template. The nanocavities in the hydrogel produced after the removal of the template bind to and recognize creatinine in the serum samples. The binding is selective and specific for creatinine. The binding is observed as shrinkage of the hydrogel volume and a decrease in the particle spacing which is monitored through changes in the Debye diffraction ring diameter and a visible blue-green to blue color shift. The binding event and the mechanism are investigated by molecular dockings. The CIPC sensor demonstrates a limit of detection (LOD) of 2.45 ± 1.6 µM, a linear detection range (25–500 µM), and recovery from 85.6 % to 99.9 % in the serum samples. CIPC hydrogel is available for the rapid and quantitative onsite detection of creatinine in the human serum sample.
