Unlocking the stable interface in aqueous zinc-ion battery with multifunctional xylose-based electrolyte additives

Journal of Energy Chemistry 2025年第1期100卷 770-778页

作者： Xiaoqin Li jian Xiang Lu Qiu Xiaohan Chen Yinkun Zhao Yujue Wang Qu Yue Taotao Gao Wenlong liu Dan Xiao Zhaoyu Jin Panpan Li Institute for Advanced Study Chengdu University School of Mechanical Engineering Chengdu University College of Food and Biological Engineering Chengdu University Institute of Fundamental and Frontier Sciences University of Electronic Science and Technology of China College of Materials Science and Engineering Sichuan University

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

人工智能已经强势出现在今天世界的舞台上。人工智能不同于以往的主、客关系(第三问题),人类还完全没有应对的基本观点、范式和全局性的研究平台。本文认为,只有在"科学与人文"和"中、西文化"这样两种"两种文化"的共同视域下,才有可能应对人类目前面临的挑战。在智能哲学论域中,研究人与人工智能的基本关系是人类对"不确定性"问题关注的一个新高度。人、机伦理关系比人、机技术关系更为根本。智能哲学的专门研究范畴如学习与模仿、直觉与"局面"等,可以在一种全新的综合性上,将人类的认知理论推向一个新高度。

Investigating the pharmacological basis and mechanisms of the anti-thrombotic effects of Paeoniae Radix Rubra， both pre- and post-stir-frying with rice wine

引用

Food Science and Human Wellness 2025年

作者： Jiaxu Zhang jian Guan Ajiao Hou Wenying Niu Haixue Kuang liu Yang Hai jiang Key Laboratory of Basic and Application Research of Beiyao， Heilongjiang University of Chinese Medicine， Ministry of Education

Paeoniae Radix Rubra (PRR) is a commonly used traditional Chinese medicine known for promoting blood circulation and alleviating pain. Stir-frying PRR with rice wine enhances its effectiveness in improving blood flow and resolving stasis. To explore the pharmacodynamic basis and mechanisms behind PRR's anti-thrombotic effects—both pre- and post-stir-frying—a comprehensive approach combining pharmacological research， metabolomics， and chemistry was employed. Fraction inter-cross validation experiments， pharmacological assessments， and metabolomic analyses confirm the efficacy of the fraction separation process. Wine-stir-fried PRR (WPRR) shows superior blood activation compared to PRR. PRR mainly affects the TCA cycle and sphingolipid metabolism pathways through its small molecules， enhancing coagulation and fibrinolysis systems' functionality. All the subdivided components of WPRR have anti-thrombotic effects， especially polysaccharides and oligosaccharides. WPRR improves thrombotic conditions in rat blood stasis by modulating arachidonic acid metabolism， TCA cycle， lipid status enhancement， and angiogenesis stimulation while regulating platelet adhesion and aggregation. In conclusion， compared with PRR， the main material basis for the blood-activating efficacy of WPRR has transformed from small molecule compounds to polysaccharide and oligosaccharide components. The action pathways of WPRR in exerting anti-thrombotic efficacy have increased. The polysaccharide components in WPRR might possess considerable potential for being developed into natural anti-thrombotic drugs.

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.
