Two-dimensional transition metal carbide/nitride (MXene)-based textiles have been developed in many fields; however, the high sensitivity to oxidation and weak interfacial bonding hinder their applications. Herein, we present a strategy for the preparation of a highly antioxidative MXene@gallic acid (MXene@GA, MG) hybrid dispersion, and further covalently grafted it onto carboxylated cotton fabric through interaction with metal ions (Fe 3+ ) for fabricating wearable multifunctional textiles. Due to the cross-linking effect of Fe 3+ and the remarkable antioxidant activity of natural polyphenol GA, the MG coatings firmly adhere to the textile surfaces and can withstand conventional washing, exhibiting favorable service stability and potential application prospects. Moreover, the obtained MG-decorated textile has the inherent characteristics of good breathability, moisture permeability, flexibility, and biocompatibility of the original fabric, which are conducive to the wearability of smart devices. Furthermore, by utilizing the outstanding conductivity (~ 330 S/m) and photothermal convertibility of the MG coating, the functional textile achieves high electromagnetic interference (EMI) shielding efficiency (~ 35 dB), excellent dual-driven ( Joule and solar) heating warmth retention, and infrared thermal camouflage. Due to the green and scalable preparation process, favorable durability, excellent comfort, and multifunctionality, the MG-decorated textiles are anticipated to be promising candidates for the next generation of smart wearable personal protective clothing.

Addressing the issue of color loss owing to the degradation of anthocyanins during storage in blueberry wine, we compared the stabilizing effect of phenolics on anthocyanins. Initially, the influences of phenolic co-pigments (catechin, epicatechin, gallic acid, sringic acid, and caffeic acid) on the main monomeric anthocyanin (malvidin-3-O-galactoside) in blueberry wine were evaluated in a model wine solution. Gallic acid showed the highest binding strength (binding constant K = 24.41 mol/L) and excellent thermal (half-life t 1/2 = 15.20 h) and light stability (half-life t 1/2 = 38.66 h) in the model wine solution, whereas epicatechin distinguished itself in oxidative stability (half-life t 1/2 = 11.37 h). In the subsequent storage, the blueberry wine containing epicatechin or gallic acid as co-pigments displayed markedly improved color stability, evidenced by intensified color enhancement and darker displacement, reduced color change, and maintenance of elevated levels of total phenolics, total flavonoids, and anthocyanins. This work may provide theoretical and practical guidance for stabilizing wine color during the storage of fermented fruit wines such as blueberry wine.

Pharmaceutical cocrystals are an efficient approach to improve the solubility of insoluble active pharmaceutical ingredients (APIs), while the dissolution profiles of pharmaceutical cocrystals usually exhibit a type of “spring and rapid parachute” effect that influences stability and pharmacodynamic sustainability, in which the high apparent solubility induced by the formation of cocrystals can only be maintained for a short time (usually minutes) in the metastable zone and then decreases rapidly afterwords. Herein we reported the preparation and structures of two lenalidomide cocrystals with gallic acid (1, 2). After the formation of cocrystals, the intrinsic dissolution rate and apparent solubility of lenalidomide were found to be enhanced. The high solubility of cocrystals can keep for 48 h without dropping. The result of phase solubility study indicates gallic acid (GA) forms a 1:1 complex with lenalidomide (Rev) in aqueous solution, with a stability constant of 1713.2 L/mol. The multiple hydrogen bonding interactions between GA and Rev are attributed to the formation of GA-Rev complex in aqueous solution and subsequently the constant high solubility of cocrystals.

An inexpensive adhesive bearing polyphenol groups was synthesized in this work. In order to obtain the desired adhesive, gallic acid (3,4,5-trihydroxybenzoic acid) was chosen as the functional compound to modify hydroxyl acrylate copolymer . The rheology and creep properties of the adhesive expressed that its cohesive strength and fatigue resistance were both increased. The resultant adhesive presented a better bonding strength to different substrates, such as steel, polypropylene (PP) and polytetrafluoroethylene (PTFE). In addition, reversible adhesion could be stimulated by modulating the temperature. Shear strength for PP was not less than 0.5 MPa, furthermore that for steel was no less than 4 MPa and the maximum achieved 6 MPa.

Gallic acid, known for its biological activity contributing to human health, including antioxidant, anti-inflammatory, anticancer, and antimutagenic properties, was the focus of this study. The solubility of gallic acid was experimentally measured in pure and mixed solvents of water, ethanol, and acetic acid and predicted using the COSMO-SAC model and the Hansen solubility parameter. The Hansen solubility parameter method predicted a higher solubility of gallic acid in pure water than in pure ethanol, and in a mixed solvent, it predicted the maximum solubility at 80% water content, showing different results from the experimental data trends. However, using the molar volume obtained from COSMO calculations resulted in a tendency that matched the experimental results. The results revealed higher solubility in ethanol compared to water, with the solubility in mixed solvent falling within the range between them. Using the same method, the Hansen solubility parameter obtained was applied to acetic acid/water and acetic acid/ethanol mixtures, and similar trends were observed compared to experimental data. In particular, gallic acid in the acetic acid/water mixture solvent exhibited maximum solubility, and this phenomenon was well-predicted. As the temperature increased, solubility in both pure and mixed solvents also increased. While the COSMO-SAC model effectively captured this trend, the predicted solubility values were slightly lower than the experimental data. The solubility trends depending on solvent types were confirmed by comparing the σ-profiles of each compound. The σ-profile of gallic acid closely resembled that of ethanol, and this result led to higher solubility than water and acetic acid. The maximum solubility in ethanol/water and acetic acid/water mixed solvents could be anticipated when two solvents with significant differences in their σ-profiles are mixed in an appropriate ratio.

Gallic acid (GA) is widely used in beverages, food, and other fields as antioxidant. However, GA is slightly toxic and the accumulation of GA is harmful to human body. Therefore, it's vital to develop simple and sensitive detection methods for GA. In this work, a novel ratiometric fluorescent nanoprobe (named CoOOH/OPD/SiNPs) for the GA detection in different foods was designed and prepared. The fluorescence of silicon nanoparticles (SiNPs) at 443 nm would be quenched by cobalt oxyhydroxide (CoOOH) nanoflakes. o -phenylenediamine (OPD) would be oxidized to 2,3-diaminophenazine (DAP) by CoOOH nanoflakes that have peroxidase-like activity, which produces a new fluorescent peak at 556 nm. Meanwhile, SiNPs' fluorescence would be quenched through DAP due to inner filter effect (IFE). With the addition of GA, the reductive decomposition of CoOOH decreased DAP level, causing IFE being restrained. The concentration of GA indicates an excellent linear relationship with fluorescence ratio (F 443 /F 556 ) in range of 0.4–12 μM (R 2 = 0.9937) with 0.16 μM detection limit. This nanoprobe is applied to GA detection in water, tea leaves, fruits and nut fruits, which would be expected to act as a portable device for complex substances analysis.

In this study, diatomite was refined by a simple purification method consisting of calcination combined with acid washing. Optimal purification conditions were the focus, including the influence of conditions on diatomite morphology, structure, and specific surface area. The results showed that the optimal conditions were a 550 °C carbonization temperature and 25 wt% HCl. This purified diatomite was then employed to adsorb gallic acid (GA) from molasses wastewater in a series of adsorption experiments, which illustrated that (ḭ) GA adsorption fitted a pseudo-second-order model and the Freundlich equation better with GA adsorption by purified diatomite; (ḭḭ) the adsorption process was physical, nonspontaneous, and endothermic; (ḭḭḭ) the maximum GA adsorption capacity by purified diatomite was 19.852 mg g −1 . This study reported the examination of a promising material for sugar mill wastewater pretreatment .

Fe 2+ is widely used for effective peroxymonosulfate (PMS) activation to eliminate refractory organics. However, Fe 2+ /PMS process suffers from difficulty on Fe 2+ regeneration. Herein, we report an Fe 3+ /PMS process by using gallic acid (GA) as an effective promotor for efficient degradation of bisphenol A (BPA). The process exhibited considerable oxidation performance in the pH range of 3.0–10.0. Higher concentration of Fe 3+ /GA complex exhibited better BPA degradation performance whereby BPA could be completely degraded within 4 mins. Reactive oxidation species (ROS) quenching experiments, electron paramagnetic resonance (EPR) analysis, and methyl phenyl sulfoxide (PMSO) probing experiments revealed that sulfate radical (SO 4 •− ), hydroxyl radical (HO • ), and ferryl species are involved and responsible for the BPA degradation. Electrochemical analysis and density function theory (DFT) calculation explored that the self-oxidation of GA boosted the reduction of Fe 3+ into Fe 2+ for continuous activation of PMS. The GA boosted Fe 3+ /PMS system reached an intriguing mineralization efficiency of 86.4%. Findings from this work proposed references to improve the oxidation performance of Fenton-like reaction and provided new sight into the Fe 3+ /Fe 2+ cycling. Gallic acid significantly promoted the Fe 3+ /Fe 2+ cycling. The oxidation performance of Fe 3+ /peroxymonosulfate could be largely elevated by gallic acid. More than 86.4% of BPA could be mineralized by the Fe 3+ /peroxymonosulfate/gallic acid process.

The therapeutics for nephrolithiasis have created an awareness of the potential effects of crystal modifiers on the biocrystallization process. The crystallization of calcium oxalate, a primary constituent of kidney stones, is confirmed to be inhibited by natural or synthetic modifiers, but the induction of calcium oxalate dihydrate and trihydrate, which is likewise effective for retardation of stone formation, is rarely focused on. Herein, we performed a systematic investigation of the effect of gallic acid, a natural polyphenol, on the nucleation of calcium oxalate from both experimental and simulation approaches. Our results reveal that the solution species of gallic acid alter the nucleation pathways of calcium oxalate and induce the formation of different types of amorphous structures corresponding to calcium oxalate hydrates. Different species of gallic acid regulate the formation of three types of amorphous calcium oxalates (ACOs) by incorporating the proper water contents and specific interactions. Fluorescence microscopy further demonstrates clearly the incorporation of gallic acid in the nucleated calcium oxalate precipitates. These findings unveil the nucleation mechanism of different calcium oxalate hydrates with the inclusion of modifiers and provide insights for an understanding of stone formation and its potential inhibitors.

This paper describes a novel fluorescence gold nanoparticles probe for detecting cyromazine . Gold nanoparticles (GNPs) were synthesized in one step at ambient temperature using gallic acid (GA) as reducer and stabilizer. Typically the prepared GNPs with the average diameter of ∼37 nm can emit stable fluorescence at 318 nm when the excitation wavelength was selected as 296 nm. Upon the addition of cyromazine, the reducer GA can interact with cyromazine through strong hydrogen-bonding interaction, which can interrupt the formation of gold nanoparticles. Consequently, the color change from purple to yellow-green with increasing cyromazine concentration was observed, coupling with the solution fluorescence intensity weaken at the same time. Because of the unconspicuous color change, we focus on detecting the change of the fluorescence intensity. Under the optimum conditions, the weakening of the fluorescence intensity exhibited a linear dependence on cyromazine concentration in range of 0.07–5.90 μM. The selectivity of cyromazine over other metal ions and pesticides in aqueous solution is remarkably high with a low detection limit of 0.07 μM. In the analysis of practical spiked milk and pet food samples, the new method yielded satisfactory results. This approach offers several advantages including simplicity (without temperature control and GNPs modification), speediness, high selectivity and sensitively, and a large linear range.

Lignin is regarded as the most abundant renewable aromatic compound on earth. In this study, we established Escherichia coli-based whole-cell biocatalytic systems to efficiently convert two lignin-derived substrates (ferulic acid and p-coumaric acid) to gallic acid. For the synthesis of gallic acid from ferulic acid, we used the recombinant E. coli expressing feruloyl-CoA synthetase and enoyl-CoA hydratase/aldolase from Pseudomonas putida, aldehyde dehydrogenase (HFD1) from Saccharomyces cerevisiae, vanillic acid O-demethylase (VanAB) from P. putida, and a mutant version of p-hydroxybenzoate hydroxylase (PobAY385F) from P. putida. Under the fed-batch mode, 19.57 mM gallic acid was obtained from 20 mM ferulic acid with a conversion rate of 97.9%. To achieve gallic acid synthesis from p-coumaric acid, we replaced VanAB with the two-component flavin-dependent monooxygenase (HpaBC) from E. coli. Under optimal conditions, 20 mM p-coumaric acid afforded the production of 19.96 mM gallic acid with near 100% conversion. To the best of our knowledge, our work represented the first study to develop E. coli-based whole-cell biocatalysts for the eco-friendly synthesis of gallic acid from lignin-derived renewable feedstocks.

Abstract In the study, a novel mesoporous curcumin (CUR)−gallic acid (GA) self-assembled nanoparticles (CUR-GA NPs) were prepared via hydrogen bonding, π−π stacking, and hydrophobic interaction. The CUR-GA NPs and IR-820-loaded composites (CUR-GA@IR-820 NPs) have strong near-infrared (NIR) light absorption. The photothermal conversion efficiency of CUR-GA NPs and CUR-GA@IR-820 NPs can reach 24.9% and 38.6%, respectively. CUR-GA NPs can not only achieve drug release in an acidic environment but also can be a nanocarrier to load and release the DOX. The CUR-GA NPs demonstrated excellent pH-responsive drug release performance. The cumulative release of CUR-GA NPs and CUR-GA@DOX NPs can reach 70.02% (CUR), 67.22% (GA) and 67.16% (DOX), respectively. The novel CUR-GA NPs provided a reliable nanocarrier for chemotherapy and photothermal therapy.
