1Recent advances in ionic liquids-based hybrid processes for CO_(2) capture and utilization显示文摘CO_(2) capture and utilization(CCU)is an effective strategy to mitigate global warming.Absorption,adsorption and membranes are methods used for CO_(2) separation and capture,and various catalytic pathways have also been developed for CO_(2) utilization.Although widely researched and used in industry,these processes are energy-intensive and this challenge needs to be overcome.To realize further optimization,novel materials and processes are continuously being developed.New generation materials such as ionic liquids(ILs)have shown promising potential for cost-effective CO_(2) capture and utilization.This study reviews the current status of ILs-based solvents,adsorbents,membranes,catalysts and their hybrid processes for CO_(2) capture and utilization.The special properties of ILs are integrated into new materials through hybridization,which significantly improves the performance in the process of CCU.Shaohan Lian Chunfeng Song Qingling Liu Erhong Duan Hongwei Ren Yutaka Kitamura 2021Journal of Environmental Sciences2021,33,1:9

3African swine fever virus MGF505-3R inhibits cGAS-STING-mediated IFN-βpathway activation by degrading TBK1显示文摘African swine fever virus(ASFV)is an important pathogen causing acute infectious disease in domestic pigs and wild boars that seriously endangers the global swine industry.As ASFV is structurally complex and encodes a large number of functional proteins,no effective vaccine has been developed to date.Thus,dissecting the mechanisms of immune escape induced by ASFV proteins is crucial.A previous study showed that the ASFV-encoded protein is an important factor in host immunity.In this study,we identified a negative regulator,MGF505-3R,that significantly downregulated cGAS/STING-and poly(dG:dC)-mediated IFN-βand interferon stimulation response element(ISRE)reporter activity and suppressed IFNB1 and IFIT2 mRNA levels.In addition,TBK1,IRF3 and IκBαphosphorylation levels were also inhibited.Mechanistically,MGF505-3R interacted with cGAS/TBK1/IRF3 and targeted TBK1 for degradation,thereby disrupting the cGAS-STING-mediated IFN-βsignaling pathway,which appears to be highly correlated with autophagy.Knockdown MGF505-3R expression enhanced IFN-βand IL-1βproduction.Taken together,our study revealed a negative regulatory mechanism involving the MGF505-3R-cGAS-STING axis and provided insights into an evasion strategy employed by ASFV that involves autophagy and innate signaling pathways.Mingyang Cheng Jiawei Luo Yuetong Duan Yu Yang Chunwei Shi Yu Sun Yiyuan Lu Junhong Wang Xiaoxu Li Jianzhong Wang Nan Wang Wentao Yang Yanlong Jiang Guilian Yang Yan Zeng Chunfeng Wang Xin Cao 2022Animal Diseases2022,2,3:1

6Oscillating chemiluminescence in rhodamine B-induced Belousov-Zhabotinsky reaction catalyzed by Ce(Ⅳ)显示文摘It was found that rhodamine B could induce oscillating chemiluminescence (OCL) from the Ce4+-cata-lyzed Belousov-Zhabotinsky reaction. This new OCL system, i.e., rhodamine B-malonic acid-bromate-Ce(Ⅳ)-sulfuric acid, exhibited two clearly distinguished emission peaks in each oscillation period. The initial concentrations of the reactants strongly influenced the oscillation pattern. For the study of the CL mechanism, a platform for a versatile and simultaneous potential and CL measurement was estab-lished to compare the potential oscillation with the CL oscillation behavior of this system. The CL spectra, UV-visible absorption spectra and time-resolved fluorescence spectra of this OCL system were studied. A possible, simplified mechanism for the OCL is proposed. It is suggested that the generation of the two CL peaks is likely due to the oxidation of the intermediate of rhodamine B by Ce(Ⅳ) and Br2, respectively. This work provided a new method and platform to research the complex chemical oscilla-tions.DUAN ChunFeng LIU GuangMing ZHANG ZhiFeng CUI Hua 2009Chinese Science Bulletin2009,54,11:0
