hydrogen neutral moleculesinterstellar moleculesorganic compoundsperturbation theorypositive ionsWe have been studying the possibility of H 2 formation mediated by the radical cations of gaseous polycyclic aromatic hydrocarbons (PAHs). In this study, we explored the catalytic role of both outer and inner ...
POA originates from direct emissions from primary sources, while SOA is formed through the oxidation of volatile organic compounds (such as aromatic compounds)4. Studies have indicated that the OA component of atmospheric fine particulate matter can constitute up to 90% of the total PM2.5 mass ...
utilized in this work is a simplistic linear model, the contribution of features to the synthesis feasibility of compounds can be obtained by straightforward analyzed normalized coefficients. Positive feature coefficients indicate the positive relationship between feature values and synthesis feasibility, and ...
ROS are a series of oxygen-containing compounds, such as hydroxyl radical (OH), superoxide (O2−), hydrogen peroxide (H2O2), organic peroxides (ROOR’), and peroxynitrite (ONOO−) (Apak, Guclu, & Capanoglu, 2016). In nature, ROS come from the activation of oxygen molecules by solar...
and generally each family is responsible for the transport of a single class of compounds1. Despite only weak sequence homology, MFS members share a remarkable structural conservation. MFS proteins contain two halves, the N- and C-terminal domains, each formed by a bundle of six or seven trans...
As shown in the Fig.6, there were 21 VOCs could be detected by GC-MS. Dibromochloromethane, tetrachloroethane, 1,2-dibromoethane, ethylbenzene, o-xylene, m-xylene and p-xylene were the main compounds in VOCs. And dibromochloromethane emission was the maximum under FeCl3 + CaO conditio...
It can be inferred that the TP was mainly composed of organic phosphorus compounds. The correlations among NH4+-N, TP, and organic indicators were consistent with the developed agricultural background in the research area. 3.2. Comprehensive Evaluation of Water Quality Based on WQI In order to ...
Vacuum swing adsorption (VSA) using silica gel (SG) proved to be a promising method for the recovery of volatile organic compounds (VOCs). Sui [96] systematically investigated the removal and recovery of o-xylene, a typical volatile organic compound (VOC), from silica gel by the vacuum swing...
(non-hydrogen atom); p means one additional polarization function for the hydrogen atom adds a polarization function; + means to add a dispersion function to the heavy atom; if the hydrogen atom also wants to add a dispersion function, then + is replaced by ++ [31]. The larger the basis...
(cation/anion) of the linear regression was 0.78, 0.85, 0.64, and 0.59 in spring, summer, autumn, and winter, respectively. All of the slopes are significantly lower than 1, which could be best explained by the presence of hydrogen ions (H+) [20,28], implying that the aerosol ...
