Abstract Although additives are widely used in aqueous electrolytes to inhibit the formation of dendrites and hydrogen evolution reactions on Zn anodes, there is a lack rational design principles systematic mechanistic studies how select suitable additive regulate reversible plating/stripping chemistry. Here, using saccharides as representatives, we reveal that electrostatic polarity non‐sacrificial critical descriptor for their ability stabilize anodes. Non‐sacrificial found continuously...

In this study, five different kinds of polysaccharides (AAP1, AAP2, AAP3, AAP4, and AAP5) were extracted from varieties Auricularia auricula through an alkali extraction process. Furthermore, the crude deproteinized by Sevag method. produced in Shanxi province had highest content polysaccharide, 53.02%. The monosaccharide composition was determined GC Their antioxidant capacities vitro assessed radical-scavenging capacity (DPPH, superoxide, hydroxyl radicals), metal chelating ability...

Exploring the mechanisms underlying abnormal glycemic traits is important for deciphering type 2 diabetes and characterizing novel drug targets. This study aimed to decipher causal associations of circulating proteins with fasting glucose (FG), 2-h after an oral challenge (2hGlu), insulin (FI), glycated hemoglobin (HbA1c) using large-scale proteome-wide Mendelian randomization (MR) analyses. Genetic data on plasma proteomes were obtained from ten proteomic genome-wide association studies...

With the rapid development of urbanization, various urban problems such as air pollution, heat islands, poor ventilation, and so on have followed. Ventilation corridors can improve internal ventilation conditions a city effectively alleviate these problems. Taking Kaifeng an example medium-sized city, this study used meteorological analysis remote sensing (RS) technology geographical information system (GIS) to plan corridors. Through thermal environment, influential factors underlying...

Although energy-related factors, such as energy intensity and consumption, are well recognized major drivers of carbon dioxide emission in China, little is known about the time-varying impacts other macrolevel nonenergy factors on emission, especially those from macroeconomic, financial, household, technology progress indicators China. This paper contributes to literature by investigating predictive ability 15 for China’s 1982 2017 with a dynamic model averaging (DMA) method. The empirical...

As one of the main driving forces for change in surface energy balance, land use and cover affects ecological climate through different levels biogeochemical physical processes. However, many studies on balance are conducted from perspective biogeochemistry, ignoring By using core methods such as algorithm Mann-Kendall trend test, we analyzed mechanism effects five types Huang-Huai-Hai Basin China. The results showed that: (1) net radiation latent heat flux increased significantly, their...

In this study, antioxidant effects <em>in vitro</em> and vivo</em> by the <em>Caenorhabditis elegans</em> model of <em>Auricularia auricula </em> polysaccharides (AAP1, AAP2 AAP3) were used to compare these three kinds polysaccharide extraction processes (hot water extraction, enzyme alkali extraction). And monosaccharide composition was determined Gas Chromatography (GC) method. Results suggested that AAP2, which mainly composed arabinose, D-xylose, 2-Deoxy-D-arabino-hexose, mannose,...

With social changes and economic development, human activities inevitably lead to significant in land use types. Land cover change (LUCC) leads a series of energy balance surface temperature, which has an impact on the regional climate. In this study, MODIS remote sensing data were used quantify results biological geophysical effects caused by LUCC four typical cities Yellow River Basin China: Jinan, Zhengzhou, Lanzhou Xining. The showed following: (1) latent heat flux net radiation both...

Land use/cover change (LUCC) can the energy balance of earth’s surface by altering its biophysical properties (surface albedo), and it also has an important impact on ecological climate. In this paper, using algorithms, differences in resulting ecoclimatic effects under different land use changes Yangtze River basin from 2000 to 2020 were analyzed. The results showed that: (1) 2020, uptake net radiation (Rs) a downward trend with increasing intensity human activities. This indicated that...

Though the high-frequency volatility approaches are increasingly introduced to forecast financial risk in recent years, whether they can improve accuracies of forecasts remains controversial. This paper compares forecasting abilities four pairs low- and models, by calculating evaluating downside upside value-at-risk expected shortfall stock indexes portfolio. The empirical results show that, first, all models well filter serial dependence extremes, conditional standard deviation obtained...
