This pioneering study investigated the effects of sip volume on sensory perception and drinking comfort during the consumption of Jiangxiangxing Baijiu (JB). Six sip volumes (6, 9, 12, 15, 18, and 20 mL) were tested with 30 participants (15 males and 15 females). Results revealed gender-specific preferences: females tended to prefer sip volumes of 9–12 mL, while males were more likely to favor 18 mL. Using Temporal Dominance of Sensation (TDS) and Check-All-That-Apply (CATA) methods, it was found that oral sensations of sweetness and sauce flavor, as well as post-pharyngeal sensations of “smoothness,” “mellowness,” and “lingering aftertaste,” enhanced drinking comfort. In contrast, oral sensations of spiciness and bitterness, along with post-pharyngeal sensations of “pungency,” “thinness,” “blandness,” and “momentary aftertaste,” impaired comfort. Notably, females may place greater emphasis on oral perception, whereas males could focus more on post-pharyngeal sensations. A novel flavor analysis identified 20 key compounds that influence JB perception. The insights from this research provide valuable contributions to improving the drinking experience of JB.

The treatment of semi-coking wastewater generated during the semicoke production process has long been a bottleneck restricting the development of the coal chemical industry. The Fenton reaction is recognized as one of the most effective strategies for addressing water pollution; however, the susceptibility to mineralization and poor reusability of highly active catalysts has limited their practical application. Herein, a thermoplastic polyurethane (TPU) doped with oleic acid modified Mn 2 O 3 @Mn 5 O 8 (Mn 2 O 3 @Mn 5 O 8 -OA) composite fiber membrane was prepared via melt-blown spinning and blending using a melt-blown pilot setup. This composite was employed to activate peroxymonosulfate (PMS) for the degradation of semi-coking wastewater, achieving a maximum chemical oxygen demand (COD) removal efficiency of 72.4%. Material characterization confirmed successful catalyst immobilization and enhanced surface properties. Theoretical calculations provided molecular-level insights into the adsorption behavior of phenol and its degradation intermediates. The TPU-based membrane significantly improved catalyst stability and reusability while maintaining high catalytic activity, offering an effective strategy for advanced oxidation processes in complex wastewater treatment.

Efficient resource utilization of coal gasification coarse slag (CGCS) is critical for ecological sustainability and industrial economics. A low-cost, high-performance catalyst loaded with cerium-manganese oxide (CeO2–MnO2/CGCS) was prepared via an impregnation-hydrothermal synthesis. The catalytic ozonation activity of CeO2–MnO2/CGCS was evaluated based on the removal rate of chemical oxygen demand (COD) for both simulated and actual coal chemical wastewater. For simulated wastewater, the COD removal rates of phenol-, naphthalene-, and benzofuran-containing wastewater were 81.2%, 58.9% and 56.6%, respectively, with the existence of CeO2–MnO2/CGCS, and the COD removal rate of mixed simulated wastewater containing the above compounds reached 66.3%. When CeO2–MnO2/CGCS was applied to actual coal chemical wastewater, the COD decreased from 200 to 36.5 mg/L with a removal rate of 81.7%. In comparison, the COD removal rate using a commercial catalyst was 72.9%, indicating the potential industrial application of CeO2–MnO2/CGCS. Furthermore, it was demonstrated that hydroxyl radicals (·OH) are the key reactive substances in the degradation of organics by adding a free radical scavenger (5,5-dimethyl-1-pyrroline-N-oxide) into the catalytic ozonation degradation of phenol-containing wastewater. Meanwhile, the mechanism of catalytic ozonation degradation of organics in coal chemical wastewater using CeO2–MnO2/CGCS as the catalyst is also proposed.

The development of sustainable and efficient systems for the complete degradation of organic pollutants under mild conditions remains a major environmental challenge. Conventional Fenton systems often rely on externally supplied H 2 O 2 , which introduces storage and transport risks as well as additional operational costs. In this work, a polypyrrole-decorated resorcinol-formaldehyde microsphere (PPy/RF) photocatalyst was rationally constructed via in-situ oxidative polymerization to integrate photocatalytic H 2 O 2 generation and photo-Fenton oxidation within a single platform. The donor-acceptor (D-A) interfacial structure formed between PPy and RF effectively broadens visible-light absorption, accelerates charge transfer, and facilitates efficient in-situ H 2 O 2 formation. More importantly, the generated H 2 O 2 directly participates in the photo-Fenton process with Fe 3+ /Fe 2+ redox cycling, leading to the continuous generation of highly reactive hydroxyl radicals (·OH) and superoxide radicals (·O 2 − ). Under visible-light irradiation, the optimized PPy/RF-0.07 exhibited a markedly enhanced H 2 O 2 production rate (727.56 μM h −1 ) due to the D-A interfacial structure between RF and PPy promotes oxygen reduction reaction (ORR) and water oxidation reaction (WOR). Subsequently, it achieved an outstanding degradation efficiency (>99%) toward phenol, dyes, and antibiotics, outperforming conventional systems that require external H 2 O 2 dosing. This superior performance originates from the synergistic effects of enhanced interfacial charge separation, in-situ H 2 O 2 self-supply, and photo-Fenton-driven radical oxidation. This work demonstrates a self-sustaining photo-Fenton-like system that eliminates the dependence on external oxidants, offering a new insight for solar-driven advanced oxidation processes and sustainable wastewater treatment.

s Iron-based heterogenous catalysts play an important role in Fenton-like reactions, but their practical application is hindered by complex synthetic procedures and limited comprehension of reaction mechanisms. A straightforward impregnation and pyrolysis method was devised to synthesize a zero-valent iron (ZVI) modified carbon-based catalyst which significantly boosts PMS activation to degradation of tetracycline hydrochloride (TCH), more importantly, it elucidated the correlation between the electronic structure and the production of non-radical reactive oxygen species (ROS). The optimized catalyst demonstrates exceptional performance, achieving 97 % removal of TCH within 30 min, with a remarkable apparent rate constant ( k obs ) of 0.1962 min −1 , outperforming the pristine carbon catalyst by 11-fold. Mechanistic investigations reveal that the incorporation of ZVI facilitates redox cycling with PMS, thereby boosting the generation of diverse ROS. Theoretical calculations reveal that both radical and non-radical pathways synergistically enhance catalytic activity. This work presents a cost-effective and scalable approach to designing high-performance carbon-based catalysts for PMS activation, providing valuable insights into the development of sustainable water purification technologies for emerging contaminants.

Traditional nonbiodegradable plastics pose significant environmental hazards, whereas biodegradable plastics are free from these drawbacks. Poly(butylene dodecanedioate) (PBD) and Poly(ethylene dodecanedioate) (PED) exhibits well-rounded properties comparable to polyethylene (PE) while being biodegradable. However, its practical application is hindered by several limitations, including limited functionality and insufficient mechanical strength. To address these issues, this study incorporated polydimethylsiloxane (PDMS) as a block to synthesize a polyester-PDMS copolymer (PBDP and PEDP), thereby enhancing its performance and functionality. The introduction of flexible PDMS segments was found to significantly improve the mechanical properties of the material, with the elongation at break increasing from 355% for PEDP0 to 534% for PEDP4, and the impact strength improving from 259 J/m to 369 J/m. Owing to its low surface energy, PDMS enriches the material surface, endowing the synthesized block copolymer with enhanced antifouling and hydrophobic properties, as evidenced by an increase in the contact angle from 75° for PEDP0 to 97°. These improvements significantly broaden the application potential of PED-based materials. Given the minimal differences in structure and postmodification between PBD and PED, this paper primarily uses PED as the representative case for analysis. Relevant data and figures for PBD are available in the Supporting Information.

Nanosheet materials are tremendously attractive for their specific planar architecture and large surface area. However, fabricating nanosheet structures with morphological and functional control across spatial domains from the 2D to 3D scale remains a great challenge. Herein, we report a facile one-pot strategy for creating nanosheets with tunable geometries and multilevel hierarchies based on a liquid crystalline (LC) block copolymer. By finely tuning the assembly conditions, a variety of nanosheet morphologies were achieved, including multilayer leaf-like nanosheets (MLNs), multilayer rectangular nanosheets (MRNs), 3D stacked leaf-like nanosheets (SLNs), 3D stacked rectangular nanosheets (SRNs), and stacked flower-like nanosheets (SFNs). The formation of diverse nanosheet structures relies on LC ordering and the nucleation and growth tendencies of the copolymer. Particularly, we demonstrate that these hierarchical nanosheets are promising additives for polymer reinforcement. By mimicking biological reinforcing principles, SLNs integrating a large surface area with layered and anisotropic characteristics exhibit efficient toughening and strengthening effects through effective energy dissipation and crack deflection. This study not only offers a facile strategy for the design of nanosheet materials with precise control of their morphologies and dimensions but also provides new insight into using hierarchical nanosheet structures to achieve advanced polymer performance.

The synthesis of covalent organic polymers (COPs) with abundant active sites remains challenging. To address this, we developed β-cyclodextrin (β-CD) functionalized COPs through a modular synthesis strategy, which was comprehensively characterized and subsequently employed as a stationary phase for capillary electrochromatographic separations. Compared with the unmodified column, the β-CD-functionalized COP monolithic column exhibited better separation performance for analytes spanning a wide range of physicochemical properties, including monosubstituted benzenes, alkylbenzenes, phenols, isomers, and chiral compounds, achieving baseline resolution > 1.5 for all tested compounds and a maximum column efficiency of 35 013 plates m −1 for chlorobenzene. Experiments and non-covalent interaction analysis indicated that the synergistic effect between the β-CD cavity and aromatic groups enables the β-CD-functionalized COP stationary phase to exhibit multiple interaction modes (e.g., hydrophobic, π …π stacking, and hydrogen bonding), providing a theoretical foundation for the experimental data. Moreover, the column demonstrated good repeatability and stability, with relative standard deviations for intra-day, inter-day, and column-to-column repeatability all below 2.1%. The column was successfully applied to the determination of monosubstituted benzenes in wastewater samples, showing satisfactory linearity ( R 2 ≥ 0.998), which confirms its potential for complex sample analysis.

Helicobacter pylori (H. pylori) infection has emerged as a serious risk factor for global human health. Current antibiotic-based clinical eradication therapies still have many challenges, including inadequate drug permeability across the gastric mucus barrier, H. pylori biofilm-induced antibiotic resistance and recurrent infections, as well as gut dysbacteriosis. Herein, we report a probiotic-nanozyme hybrid system (LP@FeTA/CuPt), which is formed by coupling polyphenol-coated Lactobacillus plantarum (LP@FeTA) and CuPt nanozymes. LP@FeTA effectively penetrates the gastric mucus barrier via autokinetic movement, and facilitates the targeted delivery of CuPt nanozymes within H. pylori biofilms by "eating" extracellular polymeric substances (EPS). CuPt nanozymes respond to the acidic and H 2 O 2 -rich biofilm microenvironment to generate reactive oxygen species (ROS) and release Cu ions, thereby achieving multi-target eradication of biofilms by interfering with H. pylori flagellar self-assembly, urease activity, outer membrane function and energy metabolism. Importantly, LP@FeTA/CuPt can be degraded by transferrin at the infection site, allowing the released CuPt nanozymes to reactivate the antibacterial immune functions of macrophage, thus eliminating biofilm-escaped bacterioplankton to prevent recurrent infections. Notably, LP@FeTA/CuPt also modulates gut microbiota homeostasis. This study provides a promising non-antibiotic therapeutic strategy for H. pylori infection.

Background Sleep deprivation is closely associated with metabolic dysregulation, yet effective preventive interventions remain limited. Although Rhodiola rosea ( R. rosea ) exhibits promising sleep-modulating potential, the specific active components mediating its effects and the underlying mechanisms remain poorly elucidated. Purpose This study aimed to identify the sleep-regulatory component of R. rosea and elucidate its molecular mechanism. Methods A bioactivity-guided fractionation strategy was applied using a sleep-deprived Drosophila melanogaster model. The active fraction was purified and structurally characterized by chromatographic separation and spectroscopic analyses. Sleep behavior, circadian rhythmicity, oxidative stress indices, neurotransmitter levels, lipid metabolic parameters, and brain transcriptomic profiles were systematically evaluated. Mechanistic validation was performed using neuronal genetic manipulation and dual-luciferase reporter assays targeting lipid metabolism-related pathways. Results An acidic glycopeptide fraction derived from R. rosea (WRPA, 76 kDa) markedly increased total sleep duration by approximately 20%, reduced sleep fragmentation by approximately 20%, and improved circadian stability, locomotor activity, and cognitive performance in sleep-deprived flies. WRPA significantly alleviated oxidative stress by reducing reactive oxygen species (ROS) and malondialdehyde (MDA) levels and restoring antioxidant capacity, while normalizing gamma-aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT) levels in the brain. Transcriptomic analysis revealed lipid metabolism as the primary pathway modulated by WRPA, with acetyl-CoA carboxylase (ACC) identified as a key target. WRPA suppressed ACC expression by inhibiting sterol regulatory element-binding protein (SREBP)-mediated transcription, leading to decreased triglyceride, cholesterol, and free fatty acid accumulation. Importantly, WRPA effectively rescued sleep disturbances induced by neuronal ACC overexpression, confirming an SREBP/ACC-dependent mechanism. Conclusion WRPA is identified as a novel sleep-regulatory acidic glycopeptide derived from R. rosea , which restores sleep homeostasis by maintaining lipid metabolic stability through the SREBP-ACC signaling axis. These findings expand the pharmacological repertoire of R. rosea beyond small molecules and highlight glycopeptides as promising lead candidates for metabolic sleep disorder intervention.

High concentration of surfactant, lipid, metal salts, tanning agent, dye and other leather auxiliaries contain in wet-blue, crust leather and tannery wastewater. The existence of these complicated matrices seriously affects the performance of analytical instruments and the accuracy of conventional analytical methods. In this study, to effectively avoid matrix interference of leather and tannery wastewater by simple pretreatment process, thermo-magnetic dual-template molecularly imprinted polymers (TM-dt-MIPs) were prepared and used as magnetic solid-phase extraction (MSPE) adsorbent to simultaneously selective extract ten kinds of phenols (phenol, five chlorophenols (CPs), and four alkylphenols (APs)), coupled with HPLC analysis. The TM-dt-MIPs prepared by stimuli-responsive imprinting and multi-template imprinting techniques utilized magnetic graphene oxide-multiwalled carbon nanotubes as supporting material, N-isopropyl acrylamide and methacrylamide as functional monomers, 2,4-dichlorophenol and nonylphenol as dual template, showing uniform morphology, high magnetic property and thermal stability. Crucially, the thermo-sensitivity and adsorption ability for target phenols were assessed through thermo-regulated capture/release, static, dynamic and selective adsorption studies, confirmed that the adsorption and desorption of the target analytes could be effectively controlled by external temperature regulation and magnetic manipulation. The developed TM-dt-MIPs-MSPE-HPLC method exhibited excellent analytical performance, characterized by high enrichment factors (26.63–110.4), wide linear ranges (2–200 μg L −1 ), low limits of detection (0.10–0.36 μg L −1 ), limits of quantitation (0.34–1.21 μg L −1 ) and good precision (intra-day RSD: 1.61–6.84%; inter-day RSD: 2.15–8.51%). For the analysis of ten phenols in crust leather, wet blue, and tannery wastewater samples, satisfactory recoveries were achieved ranging from 72.27 to 119.6%, demonstrating the practical application prospects for trace phenol analysis in leather industrial matrices.

Poly(p-phenylene-2,6-benzobisoxazole) (PBO) fiber, made from a rigid-rod isotropic crystal polymer, exhibits exceptional tensile strength, thermal stability, and creep resistance, surpassing Kevlar fiber (one of high-performance bullet proof fibers) with twice the strength and modulus. However, UV exposure cleaves the oxazole rings in PBO’s molecular structure, leading to decreased crystallinity, reduced mechanical strength, and limited suitability for outdoor applications. This study introduces a novel surface enhancement method using an olefin addition reaction with an azobenzene polyepoxy (Bt-APDB-BA-GMA) coating for Ultraviolet (UV) resistance. Further combining this with nano titanium dioxide (TiO 2 ) forms an organic-inorganic layer for additional protection. Comparative studies were conducted on three samples, including original PBO fibers (PBO), PBO fibers modified with azobenzene/epoxy copolymer (PBO/azo-epoxy), and PBO fibers modified with both azobenzene/epoxy copolymer and nano TiO 2 (PBO/TiO 2 @azo-epoxy). Modified fibers showed significant improvements: PBO/TiO 2 @azo-epoxy exhibited a 63 % higher pull-out strength (34.58 MPa) and retained 78.2 % tensile strength after 288 hours of UV aging, compared to 28.2 % for unmodified fibers. This innovation enhances PBO fiber durability, UV resistance, and interfacial bonding, paving its way for broader applications in body armor, aircraft, and advanced technologies.
