Malvacin-3- O -galactoside (M3G) is the most abundant anthocyanins component in blueberries and has high biological activity. We investigated the effect of a pulsed electric field (PEF) on the interaction between whey protein (WP) and M3G. Stability experiments showed that PEF significantly improved stability of the anthocyanin-whey protein complex (M3G-WP), particularly at 15 kV/cm for 30 min. PEF-treated M3G-WP (PEF-M3G-WP) was used as a model of silica-induced lung fibrosis to investigate its anti-inflammatory activity and molecular mechanisms. Both in vivo and in vitro experiments demonstrated that PEF-M3G-WP alleviated inflammation in macrophages. It upregulated the expression of PINK1 and Parkin and downregulated the expression of NLRP3, CASP1, and GSDMD NT. Furthermore, qPCR experiments showed that PEF-M3G-WP inhibited the release of inflammatory factors IL1b and IL18 by upregulating Atg5 and downregulating P62 in alveolar macrophage cell lines (MH-S). In summary, PEF-treated M3G-WP may be a potential method for alleviating pulmonary fibrosis.

Cocoa aroma is a pleasant and highly market-accepted aroma type in white tea, yet its underlying key aroma components remain unclear. In this study, sensory quantitative descriptive analysis (QDA), gas chromatography–mass spectrometry (GC–MS), gas chromatography-olfactometry (GC-O), molecular docking , and aroma addition tests were employed to elucidate the aroma characteristics and aroma profile of cocoa aroma white tea (CCWT), traditional white tea (WT) and cocoa beans (CC), and then construct a comprehensive aroma flavor wheel. It was observed that CCWT consists of a composite aroma dominated by Cocoa aroma, accompanied by flowery, sweet, and herbal aroma. Ten compounds were identified as key aroma constituents in CCWT, including linalool , nerol , and β-ionone. Notably, isovaleraldehyde , 2-methylbutyraldehyde, and phenylacetaldehyde were identified as the primary aroma components contributing to the cocoa aroma. Molecular docking results revealed that 3 key aroma components generate cocoa aroma through hydrogen bonding and hydrophobic interactions with olfactory receptors , with binding energies of less than −4 kcal/mol. The addition tests indicated that isovaleraldehyde and 2-methylbutyraldehyde primarily contribute to the cocoa aroma in CCWT, while phenylacetaldehyde likely enhances this aroma through synergistic effects with other compounds. This research provides essential scientific support for enhancing white tea quality and guiding product development. A solid foundation has been established to facilitate sustainable growth of the broader tea industry.

Industrial-level alkaline water electrolysis requires high-efficiency catalysts to achieve rapid water dissociation and hydrogen intermediate migration at an ampere-level current density. However, conventional alloy catalysts lack spatially organized, abundant site functions, resulting in poor coupling between alkaline electrolysis steps. Here, we report a new NiCoFeCuMoW high-entropy alloy (HEA) catalyst prepared by pulse electrodeposition, featuring efficient mass and charge transport. The catalyst features a three-dimensional hierarchically porous framework with tailored surface atomic configurations and chemically differentiated multimetallic motifs, enabling abundant accessible active sites, accelerated transport, and cooperative regulation of reaction intermediates. Density functional theory (DFT) calculations show that Mo/W-richdomains preferentially facilitate H 2 O dissociation, whereas adjacent NiCoFeCuMoW ensembles optimize hydrogen diffusion and intermediate stabilization via regulated d-band states, thereby establishing an efficient dissociation-diffusion cascade. The NiCoFeCuMoW HEA delivers overpotentials of only 36 mV within the hydrogen evolution reaction (HER) while exhibiting 226 mV in the oxygen evolution reaction (OER) operating in alkaline electrolytes at 10 mA cm −2 . Amazingly, the cell delivers an ultra-low electrolyte potential of 1.57 V at 120 °C and 1 A cm −2 , owing to greatly enhanced charge-mass transport and perturbed hydrogen-bond networks in the over-boiling environment, providing a scalable HEA design strategy for ampere-level industrial water splitting. The boosted electrocatalytic acitivity of new HEAs alloy catalyst under over-boiling environment. Download: Download high-res image (204KB) Download: Download full-size image

Phosphor with thermally stable and highly efficient photoluminescence (PL) is a premise/challenge for use in high-quality phosphor-converted light-emitting diodes (pc-LEDs). Herein, via a facile solid-phase sintering method in air, a negative thermal quenching (TQ) blue emitting SrGa 2 B 2 O 7 (SGB): Bi is reported, mainly associating with the underlying collaborative effect of negative volumetric thermal expansion of rigid host, heterovalent substitution (Bi 3+ → Sr 2+ )-induced V Sr /V O vacancies, and generating self-reduction ions (Bi 2+ ). For charge balance under the condition of temperature rising, both opposite process of self-oxidation (Bi 2+ to Bi 3+ ) and charge release from trap levels can compensate blue-PL loss. This phosphor is comparable to Eu 2+ /Ce 3+ -activated blue-emitting phosphors, and even boasts superior quantum efficiency (QE) and thermal stability. Via artificially codoping Na + for charge compensation, the QE of the SGB:Bi/Na can be further significantly enhanced. Color-tunable PL is achieved via cascade-connected energy transfer (ET) from Bi 3+ to Tb 3+ (green)/Eu 3+ (red) in SGB: Bi/Na/Tb/Eu that possesses high QE/stability than the case of blue/green/red tricolor phosphor blends adopted in warm white LEDs (wLEDs). Finally, the SGB: Bi/Na and SGB: Bi/Tb/Eu/Na are respectively, encapsulated with distinct encapsulants via either traditional or remote “capping” packaging strategy to form blue LEDs and wLEDs, showcasing splendid electroluminescence behaviors and luciferous application prospects.

Selective separation of precious metals from chloride-rich acidic media remains challenging because of the complex aqueous speciation of metal ions and the interference of competing ions. In this study, a polyethyleneimine (PEI)-functionalized tannin-based phenolic resin (TPR@PEI), enriched with O/N binding sites, was synthesized via Schiff base reactions for the selective separation and recovery of Au(III) and Pd(II) from complex acidic chloride solutions. The effects of key synthesis parameters, including tannic acid (TA) dosage, formaldehyde (FA) volume and crosslinking time, on adsorbent structure and Au(III)/Pd(II) adsorption performance were systematically investigated. Under the optimized synthesis conditions (1 g TA, 5 mL FA, and 2 h crosslinking time), TPR@PEI exhibited rapid adsorption kinetics, reaching equilibrium within 40 min for both metal ions. The adsorption behavior was well described by the pseudo-second-order kinetic model and the Langmuir isotherm model, with maximum adsorption capacities of 416.67 mg g −1 for Au(III) and 270.27 mg g −1 for Pd(II) at pH 2. More importantly, TPR@PEI showed superior selectivity toward Au(III) (> 99%) and Pd(II) (> 87%) in both binary and multicomponent systems, and maintained removal efficiencies remaining above 90% over five adsorption-desorption cycles. Combined characterization and density functional theory calculations (DFT) revealed that the excellent separation performance was governed by the synergistic effects of electrostatic attraction, redox interaction, and coordination/chelation enabled by the cooperative O/N-rich binding sites. These results demonstrate that TPR@PEI is a promising adsorbent for the highly selective separation and recovery of precious metals from complex chloride-rich acidic solutions.

Whisky is well-known worldwide owing to its unique flavor, and its fermentation and distillation conditions have a significant effect on its aroma. In this paper, new-make spirits were prepared by four fermentation conditions (two distilling yeasts and two fermentation temperatures), and the different stages (wort, wash, low wine, and new-make spirit) of the samples were collected. The main aroma compounds and their precursors were initially determined in wort and wash samples by GC-MS, UPLC-MS and HPLC. Results showed that Strecker degradation, reduction, and esterification occurred during the fermentation process, leading to decreased contents of amino acids and increased contents of volatile esters, alcohols, and acids. Moreover, the two distilling yeasts exhibited their respective optimal fermentation temperatures. Then, the distillation process was evaluated by two-dimensional gas chromatography–olfactory–mass spectrometry (GC×GC-O-MS), and 74 aroma compounds were found in different stages of new-make whiskies fermented by the two distilling yeasts and one brewer’s yeast. The contents of most compounds were enhanced by at least ten times after two distillations, while the contents of some sulfur compounds decreased. Finally, the feature aroma-active compounds of each new-make whisky were identified according to rOAV. These results provided theoretical and methodological support for yeast selection and process control in whisky production.

Efficient bifunctional electrocatalysts are vital for boosting water electrolysis performance. Herein, starch-derived porous carbon microspheres were synthesized under high-salinity conditions to serve as conductive templates for the in situ growth of transition metal species. Through carbonization and phosphorization, an inverse spinel composite, P-[Ni (0.15) Co (0.15) Fe (0.7) ]O–Fe 2 O 3 , was generated. The carbon microspheres provided excellent conductivity and mechanical stability, while the nanosheets offered abundant active sites and porous structures, ensuring enhanced electron transfer and strong synergistic interactions. Consequently, the optimized catalyst exhibited outstanding bifunctional performance, with low overpotentials of 217 mV for oxygen evolution and 125 mV for hydrogen evolution at 10 mA cm −2 . The assembled electrolyzer delivered 10 mA cm −2 at 1.58 V and maintained stability for 100 h. This work demonstrates a sustainable route for fabricating high-performance transition metal-based electrocatalysts using renewable starch biomass.

The effects of sucrose ester concentrations (0.1, 1.0 and 10 mM) on myofibrillar protein emulsion gel at 0.3 and 0.6 M ionic strengths were investigated. At 0.3 M ionic strength, an elevated sucrose ester concentration increased the droplet size (from 31.86 to 55.97 μm) and absolute zeta potential (from 29.60 to 47.57 mV). Furthermore, it promoted protein folding at 0.3 M ionic strength but induced unfolding at 0.6 M. Elevated sucrose ester concentration reduced the α-helix content (from 45 % to 20 %) at 0.6 M ionic strength. Molecular dynamics simulations showed that high ionic strength promoted stable binding between sucrose ester and myosin. Moreover, higher sucrose ester concentrations weakened gels, increased free water content and enhanced viscous dominance in rheology. These findings provided meaningful insights into the mechanism of the surfactant-mediated formation of myofibrillar protein emulsion gels under varying ionic strengths.

Herein, a N,S,O-doped Co/CoO/Co 9 S 8 @carbon hybrid (Co/CoO/Co 9 S 8 @NSOC) has been constructed by calcinating a Co-based metal–organic framework (Co-MOF) with 4,4-bipyridine and 2,5-thiophenedicarboxylic acid as linkers. Co/CoO/Co 9 S 8 @NSOC exhibited a high and recycled catalytic efficiency for peroxymonosulfate (PMS) activation to degrade sulfamethoxazole (SMX, 20 mg/L) with a reaction rate of 1.31 min −1 , which was 5.2 times than that of Co-MOF. The catalytic behavior should be attributed to the rich active sites, lamellar morphology, superhydrophilicity, and magnetism. Furthermore, the Co/CoO/Co 9 S 8 @NSOC was immobilized on a filter membrane (CMFM) to adapt to the flowing system, which could recycle 20 times without losing activity. To employ in a large-scale static environment, the Co/CoO/Co 9 S 8 @NSOC was loaded on the commercial sponge (CoSPG). In a 50 L water tank, the CoSPG realized to decompose 160 mg/L SMX solution with 37 h and had long-term stability over 10 days. Notably, the PMS cost of treating one ton of wastewater is only $0.34, indicating a huge industrial application value.

Pteris cretica L. var. nervosa is one of the most well-known Chinese medicines. Although it is widely used to treat jaundice hepatitis, the main ingredient for its treatment was not thoroughly explored until recently. Essentially, the purpose of this study is to find the monomer compound in Pteris cretica L. var. nervosa , which is most likely to be effective in treating liver injury. Through the model of LPS/D-gal-induced liver injury in mice, the best therapeutic site of the total extract was explored, the chemical components of the parts with the best therapeutic effect were separated, a total of 10 flavonoids were isolated, and the RAW264.7 cells induced by LPS were used as the experimental model to explore the preliminary anti-inflammatory activity of NO production in vitro. Finally, the anti-inflammatory activity and the highest content in this plant Luteolin-7-O-rutinoside (LUT) were selected, as the object of study in vivo. It was found that LUT could not only reduce alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, but also significantly reduce the release of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β), and inhibit PI3K/AKT/AMPK/NF-κB pathway. In addition, LUT can increase levels of SOD and GSH to reduce oxidative stress. It has an obvious therapeutic effect on acute liver injury induced by LPS/D-gal in mice. Therefore, infer LUT is a functional substance in Pteris cretica L. var. nervosa. Graphical abstract

Caffeoylquinic acids are existed in many plant species with various biological and pharmacological activities. 3- O -caffeoylquinic acid and 4- O -caffeoylquinic acid are two isomers of caffeoylquinic acids, which may be degraded and transformed to their isomers in processing. The present paper found that the stability of 3- and 4- O -caffeoylquinic acid had decreased with the increasing solution alkalinity. 3- O -caffeoylquinic acid was more stable than 4- O -caffeoylquinic acid at the same condition. During degradation, 3- and 4- O -caffeoylquinic acid were partially converted to their isomers. Additionally, ultrasonic effects on the degradation and isomerization of 3- and 4- O -caffeoylquinic acid at different pH were studied. Ultrasound facilitated the degradation and isomerization of these compounds. The degradation kinetics were described by the Weibull equation. The protective effect of ascorbic acid and epigallocatechin gallate were also explored. Ascorbic acid and epigallocatechin gallate could alleviate the degradation of 3- and 4- O -caffeoylquinic acid under certain conditions.

In order to form strengthened active sites for superior CO 2 adsorption on core shell ZIF-8@ZIF-67 nanocomposites , graphene oxide (GO) with oxygen-containing functional groups was used as support to synthesize hybrid adsorbents with unsaturated Zn–N 2 –O active sites. The results of XPS O 1s and FTIR analysis revealed that the Me–O functional group content in the 0.5 wt% graphene oxide (GO)-supported core shell ZIF-8@ZIF-67 nanocomposite (38.9 at.%) was much higher than that in the 0.5 wt% reduced graphene oxide (RGO)-supported nanocomposite (19.4 at.%). This was because hydroxyl functional groups in the GO formed coordination bonds with zinc atoms in core shell ZIF-8@ZIF-67. XPS N 1s spectra indicated that the incorporation of oxygen-containing functional groups in GO resulted in the transition of binding form from Me–N 4 to Me–N 2 . The CO 2 adsorption capacity of GO-supported core shell ZIF-8@ZIF-67 gradually decreased from 2.15 to 1.30 mmol/g as GO weight percentage increased from 0.5 to 4 wt%, which was consistent with the decrease in BET surface area from 1378 to 585 m 2 /g and increase in peak pore diameter from 7.7 to 8.2 Å. Density functional theory (DFT) calculations demonstrated that unsaturated Zn–N 2 –O active sites in GO-supported core shell ZIF-8@ZIF-67 nanocomposites resulted in a decreased O C⋯Zn interaction distance from 4.65 (Zn–N 4 sites in core shell ZIF-8@ZIF-67) to 3.46 Å and an increased binding energy from 34.02 to 38.87 kJ/mol. Therefore, 0.5 wt% GO-supported core shell ZIF-8@ZIF-67 nanocomposites exhibited the highest CO 2 adsorption capacity of 2.15 mmol/g (at 273 K and 1 bar), 1.34 times higher than that of core-shell ZIF-8@ZIF-67.
