| 1 | Improved dispersion performance and interfacial compatibility of covalent-grafted MOFs in mixed-matrix membranes for gas separation显示文摘Mixed-matrix membranes(MMMs)have received much attention due to their processable advantages of polymer and high permeability and/or selectivity of porous metal-organic frameworks(MOFs)fillers.However,the interfacial defects caused by poor interaction between MOFs with polymers and the agglomeration phenomenon caused by uneven dispersion of MOFs are common problems in mixed-matrix membranes.Currently,the priming protocol is one of solutions to the above problems,but it cannot precisely regulate the dispersion of particles and the interfacial compatibility between two phases.Herein,covalent grafting of polyimide 6FDA-Durene onto the surface of UiO-66-NH2 can mitigate the aggregation of fillers inside the polymeric matrices and improve the interfacial interaction between two phases,thus significantly improving the CO_(2)/CH_(4)separation performance on the as-synthesized MMMs.The explored gas transport mechanism indicated that the improved separation was due to the raise of solubility selectivity.Furthermore,the stronger covalent bond between fillers and polyimide than physical interaction of priming protocol also endows the improved anti-plasticization phenomenon for CO_(2)/CH_(4)separation. | Chongqing Wang Guangjie Ren Kaifeng Wei Donghui Liu Tingting Wu Jinlong Jiang Junfeng Qian Yichang Pan | 2021 | Green Chemical Engineering2021，2，1： | 3 |
| 2 | Serum albumin complexed with ellagic acid from pomegranate peel and its metabolite urolithin B显示文摘As one of fruit waste by-products,the pomegranate peel is rich in bioactive compounds such as ellagic acid.Ellagic acid and its main gut microbial metabolite urolithin B have been reported to exhibit numerous biological activities and widely used as dietary supplements in the past decades.Interaction of these two compounds to serum albumin(SA)might affect their metabolism,efficacy,and body distribution.The interaction of ellagic acid and urolithin B with SA was investigated and BSA interference on the anti-cancer activity of these two compounds was also evaluated.Results of spectra experiments showed that ellagic acid and urolithin B could form complexes with bovine serum albumin(BSA)and urolithin B has a higher binding force and number of binding sites than ellagic acid when forming a complex with BSA.The results of molecular docking and molecular dynamics simulations suggested that ellagic acid and urolithin B tended to bind in site I rather than site II.The MTT assay results indicated that the IC_(50) value of ellagic acid decreased from 123.58μM to 55.91μM,while the IC_(50) value of urolithin B decreased from 83.67μM to 47.40μM.Ellagic acid and urolithin B can form complexes with serum albumin and the anti-cancer activity of ellagic acid and urolithin B was enhanced when combined with BSA. | Peiyu Xue Guangjie Zhang Hongmei Zhao Wencheng Wang Jie Zhang Li Ren | 2022 | Food Bioscience2022，46，2： | 0 |
