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.

It has been reported that sea cucumber intestine hydrolysates (SCIH) could promote glutamine metabolism in mice， while there is a close connection between glutamine metabolism and insulin sensitivity. However， the effect of SCIH on insulin resistance is still unclear. The results showed that SCIH hydrolyzed by flavor protease had significant activity using the insulin-induced HepG2 cell model. Animal experiments exhibited that SCIH supplementation significantly improved the high-fat and high-sucrose diet-induced impaired glucose tolerance， reduced fasting serum glucose and glycosylated serum protein. Besides， SCIH ameliorated islet vacuolization and decreased the pancreas TNF-α and IL-6 by 32.1% and 36.2%， respectively. Immunofluorescence staining results showed that SCIH promoted insulin secretion. Interestingly， SCIH significantly increased the liver glutamine levels and upregulated the expression of glutaminase1 (GLS1) and glutamate dehydrogenase 1 (GLUD1). Furthermore， SCIH increased liver acetyl-CoA levels to enhance histone acetylation and activate the gene transcription and translation on glucose metabolism-related IRS/PI3K/AKT signaling pathway， thereby attenuating insulin resistance. The present findings proposed the potential value for developing functional foods in SCIH utilization.

Root-fed Salicylic Acid in Grape Involves the Response Caused by Aboveground High Temperature

Journal of Integrative Plant Biology 2008年第6期50卷 761-767页

作者： Hong-Tao Liu Yue-Ping Liu Wei-Dong Huang college of food science &nutntional engineenng China Agncultural University Beijing 100083 China Department of Biotechnology Beijing Agricultural College Beijing 102206 China

In order to investigate the transportation and distribution of salicylic acid （SA） from root to aboveground tissues in response to high temperature, the roots of grape plant were fed with 14C-SA before high temperature treatment. Radioactivity results showed that progressive increase in SA transportation from root to aboveground as compared with the control varied exactly with the heat treatment time. Radioactivity results of leaves at different stem heights indicated that the increase in SA amount at the top and middle leaves during the early period was most significant in comparison with the bottom leaves. The up-transportation of SA from root to aboveground tissues was dependent on xylem rather than phloem. Autoradiographs of whole grape plants strongly approved the conclusions drawn above. Root-derived SA was believed to be a fundamental source in response to aboveground high temperature.

作者：庞杰孙玉敬杨幼慧陈缘缘陈艺勤孙远明 college of food science South China Agricultural University college of Biosystem Engineering and food science Zhejiang University college of food science Fujian Agriculture and Forestry University

In this paper, the hydrogen bonding network models of konjac glucomannan （KGM） are predicted in the approach of molecular dynamics （MD）. These models have been proved by experiments whose results are consistent with those from simulation. The results show that the hydrogen bonding network structures of KGM are stable and the key linking points of hydrogen bonding network are at the O（6） and O（2） positions on KGM ring. Moreover, acety has significant influence on hydrogen bonding network and hydrogen bonding network structures are more stable after deacetylation.

Studies on Single Chain Structure of Konjac Glucomannan

引用

Chinese Journal of Structural Chemistry 2006年第12期25卷 1441-1448页

作者：庞杰孙玉敬孙远明 college of food science South China Agricultural University college of food science Fujian Agriculture and Forestry University

The simulation is carried out by employing the method of molecular dynamics with the single chain of konjac glucomannan （KGM） in vacuum as the structural model to discuss the factors that affect the single chain structure, the dynamic structure of the chain and the acting forces that maintain the chain structure. The results show that the shape and stability of the chain are affected by the degree of polymerization. As for the KGM with high degree of polymerization, its chain presents random coiling state and its stability declines. Both before and after deacetylation in the process of dynamic motion, the chain of KGM presents random coiling state with periodic variation of extension and coil and demonstrates favorable flexibility, indicating acetyl is not the main factor that affects the shape of chain, whereas dihedral angle and static actions are respectively the key bonding and nonbonding acting forces that influence the single chain conformations in vacuum.

Chinese Journal of Structural Chemistry 2008年第4期27卷 394-398页

作者：庞杰孙玉敬庄昱叶炳鸿孙远明 college of food science South China Agricultural University college of Biosystem Engineering and food science Zhejiang University college of food science Fujian Agriculture and Forestry University

Molecular dynamics （MD） method is adopted to simulate the conformation variations of konjac glucomannan （KGM） saline solution at different temperatures, and structurally analyze the trends and reasons of viscosity change in KGM saline solution with temperature. The experimental results have been analyzed to find out that the sum of formative hydrogen bonds decreases with the rise of temperature and the amount of intramolecular hydrogen bonds suddenly increases at 323 K. Besides, in terms of molecular orbital data obtained from simulation, we can know that hydrogen bonding energy also decreases with the rise of temperature. Therefore, we can predict the viscosity of KGM saline solution decreases gradually when rising the temperature.

Chinese Journal of Polymer science 2013年第9期31卷 1190-1203页

作者： Bing Hu Qing-rong Huang college of food science and Technology Nanjing Agricultural University Department of food science Rutgers University

Recently, there has been an increasing interest in the development of efficient food-grade oral nano-delivery systems for encapsulation, protection and target delivery of nutraceuticals to enhance their bioavailability, fiarther to prevent disease and promote human health and well-being. food proteins represent promising candidates for efficient nutraceutical nanocarriers due to their exceptional characteristics, namely biodegradability, nonantigenicity, high nutritional value, abundant renewable sources and extraordinary binding capacity to various nutraceuticals. In addition, their biocompatibility, biodegradability, low toxicity, low cost, and non-starch polysaccharides possess many favourable characteristics such as stability in the harsh gastric environment, resistance to digestive enzymes, and mucoadhesiveness to intestinal mucosal surface. This review describes the design and formation of nanoscaled delivery systems for nutraceuticals using food-grade proteins （including peptides）, polysaccharides and their associative complexes. The toxicity and cellular uptake fate of the nanostructures, as well as their effects on the intestinal absorption of the encapsulated nutraceuticals were also discussed.

Hot air treatment activates defense responses and induces resistance against Botrytis cinerea in strawberry fruit

引用

Journal of Integrative Agriculture 2016年第11期15卷 2658-2665页

作者： JIN Peng ZHENG Cong HUANG Yu-ping WANG Xiao-li LUO Zi-sheng ZHENG Yong-hua college of food science and Technology Nanjing Agricultural University college of Life science and food Engineering Huaiyin Institute of Technology college of Biosystems Engineering and food science Zhejiang University

The effect of hot air（HA, 45°C, 3.5 h） treatment on reducing gray mold caused by Botrytis cinerea in strawberry fruit and the possible mechanisms were investigated. The results showed that HA treatment significantly reduced lesion diameter and enhanced activities of chitinase（CHI）, β-1,3-glucanase and phenylalanine ammonia-lyase（PAL） in strawberry fruit. Total phenolic contents were also increased by HA treatment. The activities of antioxidant enzymes including superoxide dismutase（SOD）, catalase（CAT） and ascorbate peroxidase（APX） were higher in HA treated strawberry fruit than those in control. Expression of three defense related genes such as CAT, CCR-1 allele and PLA6 was greatly induced in HA treated strawberry fruit with or without inoculation by B. cinerea. In addition, the in vitro experiment showed that HA treatment inhibited spore germination and tube growth of B. cinerea. These results suggested that HA treatment directly activated disease resistance against B. cinerea in strawberry fruit without priming response and directly inhibiting growth of B. cinerea.
