Quaternization of cotton enables its dyeing with anionic dyes and thus makes it possible to dye wool/cotton blends fabrics in one bath. However, research on the impact of the structures of EQASs on the dyeing properties of modified cotton fibers remain limited. In this study, three EQASs with varying alkyl chain lengths—EMAC-4, EMAC-8, and EMAC-10—were synthesized and used to modify cotton fibers. The dyeing properties of the modified cotton fibers were then investigated. As the alkyl chain length increased, the K/S values and fixation ( F% ) of the dyes on modified cotton fibers increased, while the leveling properties were somewhat compromised. When the modifier dosage was the same, EMAC-10 showed the best performance: at 20 g/L, EMAC-10 modified cotton fibers achieved 100% exhaustion ( E% ) and more than 93.4% fixation. Computational simulations revealed that as the alkyl chain length increased, the mobility of reactive dyes decreased, the reactivity of the newly introduced hydroxy groups increased, and the reaction energy barrier with monochloro- s -triazine reactive dyes was reduced. This study enhanced the understanding of the structure-performance relationship of cationic modifiers and provided a feasible direction for the design of efficient and environmentally friendly modifiers for cotton fibers.

Fresh fruits and vegetables, rich in vitamins and essential nutrients, play an essential role in supporting human health. However, the perishability during transit and storage causes rapid degradation; consuming spoiled items poses significant health risks. Extending the shelf life of fresh produce has therefore become a key challenge for the food industry. In this study, a multifunctional composite coating was developed by integrating chlorogenic acid–zinc ion (CGA-Zn 2+ ) metal–phenolic network (MPN) particles into a polymer matrix composed of sesbania gum (SG) and biguanide-modified chitosan (Bi-Ch). Cherry tomatoes were used as the model fruit to investigate the coating's preservation effect. The CGA-Zn 2+ MPN particles provided strong antioxidant properties, which worked in combination with the antibacterial activity of Bi-Ch, enabling the coating to offer both protective and bioactive functions. The addition of MPN particles significantly improved the antioxidant capacity of the coating, increasing it from 64.83 % to 97.31 %. Moreover, the coating showed enhanced antibacterial performance. Preservation results confirmed that this composite coating effectively extended the shelf life of cherry tomatoes to 9 days at least while maintaining their quality. Cytocompatibility assays validated its safety for food applications. As a biocompatible, readily removable intervention, this approach offers considerable promise for enhancing fresh fruit stability throughout supply chains—mitigating waste and bolstering food safety.

This study investigated microbial community dynamics and their links to fermentation traits in solid-state fermentation of walnut -based soy sauce (WSS) using walnut meal-soybean meal mixtures. Via 16S rRNA sequencing and molecular docking, it analyzed the effects of three distinct starter culture treatments—Aspergillus oryzae(AO),Aspergillus niger(AN), and mixed starter culture (A. oryzae+A. niger, ON)—as well as fermentation duration on microbial diversity and physicochemical properties, aiming to clarify microbial-driven quality mechanisms. Physicochemical analysis demonstrated superior fermentation performance in the AO group, showing significantly higher amino nitrogen (NH3-N) accumulation (0.23 g/100 mL) and protease activity (30.5 U/mL) compared to the AN group, with the mixed inoculation group (ON) exhibiting intermediate results, indicatingA. oryzae’s dominant role in mixed fermentation. Via PCA and Shannon index, microbial diversity analyses revealed starter cultures shaped microbial community structure:Enterococcusand Staphylococcaceae were enriched by AO starter, andKlebsielladominated in AN group. Additionally, temporal succession of the microbiota occurred during post-fermentation of WSS, with Lactobacillales,Staphylococcus, and special flavor-producing functional flora dominating early, middle, and later stages, respectively.Staphylococcuspositively correlated with protease activity and amino nitrogen, critical for quality. Molecular docking showed major walnut polyphenols significantly affected protease activity, aiding process optimization. This research provides theoretical foundations for improving WSS production and enriches understanding of solid-state fermentation microbial ecology.

Microfluidics plays a significant role in various fields, including material synthesis, drug delivery, and disease diagnosis, and the flow velocity has a critical effect on the products. However, there is a lack of approaches for monitoring the flow velocity in the microchannel. To address this, we propose a novel fiber-optic flowmeter based on a flexible Fabry-Perot (F-P) cavity for online and non-invasive monitoring of products from the microfluidic devices. The flexible F-P cavity is constructed with a fiber-optic probe and gold-coated polydimethylsiloxane (PDMS) film, which can be easily integrated with versatile microfluidic devices through oxygen plasma bonding. Depending on the numerical investigation of film deformation under various film and fluid parameters, we experimentally characterize the sensitivity, reversibility, stability, and repeatability of this flowmeter. Then, the adaptability of the flowmeter is demonstrated by monitoring the flow velocity of seawater and sucrose solution. Moreover, we integrate this flowmeter with multiple microfluidic devices to verify the integration performance. Finally, we successfully achieve online and non-invasive monitoring of mixing efficiency, droplet diameter, and microalgae separation efficiency in the integrated microfluidic devices. This flowmeter can monitor the products from the microfluidic devices for disease diagnosis and drug delivery, with the advantages of good adaptability and easy integration.

Phenolphthalein (PHT) is always applied as an acid-base indicator but suffers from too wide a range of characterization and uneven dispersion in thin films. To solve this problem, in this work, a composite filler SiO₂@PHT-1 with a jujube cake structure was designed. The size of phenolphthalein particles was effectively regulated by intervening in the growth process of phenolphthalein nuclei through silica (SiO₂). This also improved the dispersion of PHT in fluororubber (FKM) films, as well as the indicator film's tensile strength (57.1%) and initial decomposition temperature (201.6 °C), resulting in the pH indicator film with excellent tensile properties and thermal stability. The FKM/SiO₂@PHT-1 film is also capable of determining the pH value of a solution based on color and phenomena. In addition, the dense protective layer formed by the silica retards the release of PHT in the sample solution, which contributes to the reusability of the film. This method shows great promise and can be applied to laboratory and swimming pool alkalinity testing.

Gout is a disease caused by the deposition of sodium urate (MSU) crystals in the joints and tissues. Colchicine (COL) has become the first-line drug for the treatment of acute gout due to its low price and efficacy. However, colchicine is highly cytotoxic and oral administration is prone to cause severe adverse effects on the gastrointestinal tract, liver and kidney. Therefore, this study aimed to develop a novel dermal delivery formulation for addressing the safety concerns of this drug. The researchers used ethosomes encapsulation technology to improve the skin permeability of COL. In addition, in order to improve the performance of the ethosomes, it was screened and determined that the addition of 1.0–1.5 mg of ceramide III (Cer3) per mL of ethosomes as a modifier could significantly enhance the stability of the ethosomes, Cer3/COL-ethosomes (CCE) were successfully constructed. The CCE was then mixed with a cataplasm matrix to produce a colchicine-carrying CCE cataplasm, which demonstrated the superimposed effect of the advantages of the two dosage forms, the ethosomes and the cataplasm. Compared with the traditional delivery method of COL, this topical formulation is an attractive alternative for the treatment of gout as it can achieve effective blood levels without causing fluctuations in blood levels, and has good efficacy and higher safety profile.

Thermoplastic polyurethane (TPU) electrospun membrane is an ideal substrate material, especially in waterproof breathable membranes due to its superior mechanical properties and flexibility. Herein, we fabricate a TPU-based composite membrane by decorating ground polyacrylonitrile (PAN)-derived carbon nanofibers (CNFs) through ultrasonication followed by a dip-coating of polydimethylsiloxane (PDMS). The decorated CNFs can build up roughness on the membrane, and the coated PDMS layer can protect the CNFs from detaching from the membrane and increase the mechanical properties of the composite membrane. The obtained TPU/CNFs/PDMS membrane displays excellent waterproof and breathable ability. Specifically, the air permeability of the composite membrane is 7.38 mm/s, and the moisture permeability amounted to 5610 g/m 2 /day. Besides, the TPU/CNFs/PDMS membrane exhibited an outstanding tensile strength of 19.407 MPa, elongating at a break of 155.76%. This novel TPU-based composite membrane exhibits great application potential in functional fabric, especially for personal protective fabrics.

Mural paintings reflect valuable spiritual and cultural achievements of human civilizations and serve as crucial evidence for studying ancient customs, rituals, and clothing. However, deterioration of the mural plaster layer results in a decrease in the mural’s mechanical strength, thus posing a serious threat to its preservation. Nanolime (NL) is currently one of the most widely studied inorganic nanomaterials for the consolidation of cultural heritage in general, and mural paintings in particular, due to its excellent compatibility. However, there is limited research on the application of NL for consolidating the plaster layer of mural paintings. Here, we focus on ancient tomb mural paintings (ca. 1000 CE), investigating the consolidation performance of NL for its plaster layer. NL is homogeneously synthesized in the presence of additives and subjected to size-selection through centrifugation, yielding a narrowly distributed particle size of ∼40 nm—markedly smaller than the ∼180 nm obtained without centrifugation (NL-C). This novel NL is subsequently applied to the plaster layer of the tomb mural exhibiting limited impact on its pore structure and good penetration depth (1.2∼3.5 mm), which is significantly deeper than that observed in samples consolidated with NL-C (∼1 mm). More importantly, after consolidation with NL, the surface hardness of the plaster layer increases by ∼56 %, and the surface weight loss decreases by ∼67 %, demonstrating an effective consolidation performance. This study provides technical and methodological support for the application of NL in the preservation of ancient tomb murals.

Since the key aroma compounds and bioactive profiles of Phyllanthus emblica fruit wine (PFW) driven by different yeast strains remain unclear, this study aimed to systematically evaluate the effects of five Saccharomyces cerevisiae strains on physicochemical properties, bioactive components, and volatile organic compound (VOC) profiles in PFW. Using an integrated flavoromics approach with chemometric analysis, we identified 110 VOCs. FR and D254 enhanced ester concentrations and antioxidant activity respectively, whereas strain L2323 significantly altered aroma complexity by promoting specific esters and alcohols. Multivariate analyses identified methyl nitrate and n-propyl acetate as discriminant markers among strains. Aroma-activity analyses further highlighted ethyl hexanoate, isoamyl acetate, and n-propyl acetate as major aroma contributors with distinctive strain-dependent distributions. These findings provide critical guidance for yeast strain selection and fermentation optimization to improve PFW quality, offering new insights for the development of functional fruit wines.

Algae oil contains polyunsaturated fatty acids (PUFAs) that are beneficial to human health and development. Enzymatic refining is a sustainable approach that can improve the quality and nutritional value of algae oil. However, this approach involves the use of specific enzymes to remove unwanted impurities such as phospholipids (PLs) and free fatty acids (FFAs). This study proposes a novel immobilized phospholipase, immobilized phospholipase A1 (PLA1@MCM-41-C 8 ), which serves a dual purpose: it is effective for both degumming arachidonic acid (ARA)-enriched algal oil and its subsequent deacidification. The use of PLA1@MCM-41-C 8 achieved a degumming rate of 95.9% for crude algal oil, with an ARA retention rate of up to 97.3%. The acidity of the degummed oil decreased from 14.5 to 1.1 mg KOH∙g −1 , while simultaneously producing 29.2% high-value diacylglycerol (DAG). By comparing enzymatically degummed and deacidified ARA-enriched algae oil (EDDO) with crude ARA-enriched algae oil (CO), commercialized refining algae oil (CRO), it was found that enzymatic refining had minimal impact on antioxidant stability, fatty acid composition, and oil content. In particular, the flavor characteristics of algal oil before and after enzymatic refining with PLA1@MCM-41-C 8 remained unchanged and were dominated by the main volatile compounds: alcohols and aldehydes. Compared with free phospholipase A1 (PLA1), PLA1@MCM-41-C 8 exhibited significantly improved thermostability, pH tolerance, solvent tolerance, and long-term reusability. These characteristics make it a promising candidate for complex oil refining in industrial applications.

Quality indicators and chemical composition, combined with meteorological data, were used to elucidate wheat quality differences between two Chinese provinces (Xinjiang and Henan), and the response mechanism to climate was explained. The contents of crude protein (13.37 ± 1.51 g/100 g), amylose (19.58 ± 0.86 g/100 g), and crude fat (1.37 ± 0.18 g/100 g) in Xinjiang wheat were higher than those in Henan wheat. The metabolites of wheat from two provinces were characterized to comprehensively analyze their responses to climate. Xinjiang wheat accumulated lipids and phenols to adapt to high temperatures. The alanine, aspartate, and glutamate metabolism pathway was significantly upregulated in Henan wheat in response to low temperature conditions. Temperature and sunlight were the main influencing factors and were significantly correlated with most differential metabolites. This study provided a theoretical basis for quality control and geographical origin identification of winter wheat under climate change.

With the rapid advancement of modern industry and population growth, unrestrained discharge of industrial effluent and domestic sewage has caused severe environmental pollution, which poses a severe challenge to human habitat. Owing to the unique eco-friendly characteristics, photocatalytic technology has emerged as a highly promising approach in the wastewater treatment very recently. Z-scheme heterojunction ternary photocatalysts of “ x · AgCl/ y · CoWO₄/Ag” were ingeniously designed and developed in this study, exhibiting exceptionally high photocatalytic activity for degrading micropollutants in wastewater compared with single-component photocatalysts. For instance, photocatalytic activity of AgCl/CoWO₄/Ag (reflected by the reaction kinetic parameter k ) is 7.7 times that of AgCl and 313 times that of CoWO₄, respectively. The experimental results and analysis revealed a typical Z-scheme charge transfer mechanism in these ternary photocatalyst heterojunctions, thereby confirming the structural characteristics of Z-scheme heterojunction. Furthermore, the ternary photocatalysts retained the reaction activity with virtually no change after undergoing five cycles of catalytic experiments, highlighting its excellent stability. Consequently, an underlying mechanism was proposed herein to account for the enhanced photocatalytic properties. It is believed that such ternary Z-scheme heterojunction materials expand halide-based heterojunction construction methods and promise significant implications for environmental remediation.
