| 1 | Facilitated transport separation of CO_(2) and H_(2)S by supported liquid membrane based on task-specific protic ionic liquids显示文摘Selective separation of CO_(2) and H_(2)S from CH_(4) is of importance to the natural gas upgrading because of its cor-rosivity. As is well known, amine group can recognize reversibly CO_(2) and H_(2)S with a moderate interaction. Withthis in mind, this work prepared a series of amine-functionalized supported-protic-ionic-liquid membranes(SPILMs) for the selective separation of CO_(2) and H_(2)S from CH_(4) . For comparison, aprotic ionic liquid membranewas also prepared for natural gas sweetening. The effect of temperature and transmembrane pressure differenceon the permeability of single gas and ideal selectivity of CO_(2)/CH_(4) and H_(2)S/CO_(2) were studied. Facilitated transportmechanism was studied by NMR spectra. The permeability of CO_(2) in primary amine functionalized [DMPDAH][Tf_(2)N]-based membrane decreases with the increasing transmembrane pressure, indicating a typical feature offacilitated transport membrane. The permeability of CO_(2) and the ideal selective of CO_(2)/CH_(4) are as high as 2000 barrers and 53.2 at 313.2 K in [DMPDAH][Tf_(2)N] membrane, significantly higher than those in conventional ILsmembrane. It is anticipated that these amine-functionalized SPILMs can provide alternative insight for the se-lective separation of CO_(2) and H_(2)S from CH_(4) . | Lingling Peng Mingzhen Shi Xiaomin Zhang Wenjie Xiong Xingbang Hu Zhuoheng Tu Youting Wu | 2022 | Green Chemical Engineering2022，3，3： | 2 |

| 14 | The protective effects of Levilactobacillus brevis FZU0713 on lipid metabolism and intestinal microbiota in hyperlipidemic rats显示文摘Levilactobacillus brevis FZU0713, a potential probiotic previously isolated from the traditional brewing process of Hongqu rice wine, may have the beneficial effects on improving lipid metabolism. This study aimed to evaluate the in vivo protective effects and possible mechanism of L. brevis FZU0713 on the disturbance of lipid metabolism in hyperlipidemic rats fed a high-fat diet(HFD). Results showed that oral administration of L. brevis FZU0713 could significantly inhibit obesity, ameliorate the lipid metabolism disorder, including serum/liver biochemical parameters and hepatic oxidative stress in HFD-fed rats. Histopathological result also indicated that dietary intervention of L. brevis FZU0713 could reduce the accumulation of lipid droplets in liver induced by 8 weeks HFD feeding. Furthermore, L. brevis FZU0713 intervention significantly increased the fecal levels of short-chain fatty acids(SCFAs, including acetate, propionate, butyrate, isobutyrate, valerate and isovalerate)in HFD-fed rats, which may be closely related to the changes of intestinal microbial composition and metabolic function. Intestinal microbiota profiling by 16S rRNA gene sequencing revealed that L. brevis FZU0713 intervention significantly altered the relative abundance of Coprococcus, Butyricicoccus, Intestinimonas, Lachnospiraceae FCS020 group, Ruminococcaceae_NK4A214 group, Ruminococcaceae_UCG-005 and UCG-014 at genus levels. Based on Spearman's rank correlation coefficient, serum and liver lipid metabolism related biochemical parameters were positively correlated with genera Ruminococcus, Pediococcus and Lachnospiraceae, but negatively correlated with genera Pseudoflavonifractor, Butyricicoccus and Intestinimonas. Furthermore, liver metabolomics analysis demonstrated that L. brevis FZU0713 had a significant regulatory effect on the composition of liver metabolites in hyperlipidemic rats, especially the levels of some important biomarkers involved in the metabolic pathways of arachidonic acid metabolism, primary bile acid biosynthesis, amino sugar and nucleotide sugar metabolism, taurine and hypotaurine metabolism, biosynthesis of unsaturated fatty acid, fructose and mannose metabolism, tyrosine metabolism, etc. Additionally, oral administration of L. brevis FZU0713 significantly regulated the mR NA levels of liver genes(including Acat2, Acox1, Hmgcr, Cd36, Srebp-1c and Cyp7a1)involved in lipid metabolism and bile acid homeostasis. In conclusion, our findings provide the evidence that L. brevis FZU0713 has the potential to improve disturbance of lipid metabolism by regulating intestinal microflora and liver metabonomic profile. Therefore, L. brevis FZU0713 may be used as a potential probiotic strain to produce functional food to prevent hyperlipidemia. | Xiaoyun Fan Qing Zhang Weiling Guo Qi Wu Jinpeng Hu Wenjian Cheng Xucong Lü Pingfan Rao Li Ni Youting Chen Lijiao Chen | 2023 | Food Science and Human Wellness2023，12，5： | 0 |
| 15 | Efficient conversion of H_(2)S into mercaptan alcohol by tertiary-amine functionalized ionic liquids显示文摘The resource utilization of hydrogen sulfide(H_(2)S)is of great significance in natural gas chemical industry.Described herein have developed a novel method mediated in tertiary amine-functionalized ionic liquids(ILs)to convert H_(2)S into mercaptan alcohols with enols.The effect of ILs,substra te scope,and regeneration experiments have been investigated.It is found that the conversion of 3-methyl-2-buten-1-ol by H_(2)S can reach 52%with a 50%(mol)catalyst loading of bis(2-dimethylaminoethyl)ether methoxyacetate within 12 hat 90℃.The reaction mechanism was speculated based on theoretical calculation.Besides,a plausible reaction-separation-integrated strategy was further proposed.This work reveals an effective insight into the capture and catalytic conversion of H_(2)S to high valuable mercaptan alcohol,which makes the utilization method of H_(2)S resource universal and has the potentiality for industrial application. | Wenjie Xiong Mingzhen Shi Yan Lu Xiaomin Zhang Xingbang Hu Zhuoheng Tu Youting Wu | 2022 | Chinese Journal of Chemical Engineering2022，，10： | 0 |
| 16 | Designing a green and efficient absorbent for CO_2 capture显示文摘Several task-specific ionic liquids(TSILs) with weak alkalinity have been designed based on tetraalkyl-ammonium cation and L-alanine anion([N2222][L-Ala]) for the CO2 absorption.[N2222][L-Ala]has been chosen as a green and efficient activator for methyldiethanolamine(MDEA).The densities,viscosities and absorption properties of the equimolar[N2222][L-Ala]-MDEA blended absorbents were investigated.Low viscosity and density values support the idea that blended absorbents are preferred in the industrial applications.[N2222][L-Ala]-MDEA behave similarly to the aqueous counterparts but offer more advantages,such as large absorption capacities,fast absorption rate and relatively low damage to the environment. | DAI Yue,WANG Guannan,WU Youting,ZHANG Zhibing (Separation Engineering Research Center,School of Chemistry and Chemical Engineering, Nanjing University,Nanjing 210093,Jiangsu,China) | 2011 | 化工进展2011，30，S2： | 0 |
