The absorption of CO_(2)is of importance in carbon capture,utilization,and storage technology for greenhouse gas *** the present work,we clarified the mechanism of how metal-based ionic liquids (MBILs),Bmim[XCl_(n)]_(m)(X is the metal atom),enhance the CO_(2)absorption capacity of ILs via performing molecular dynamics *** sparse hydrogen bond interaction network constructed by CO_(2)and MBILs was identified through the radial distribution function and interaction energy of CO_(2)-ion pairs,which increase the absorption capacity of CO_(2)in ***,the dynamical properties including residence time and self-diffusion coefficient confirmed that MBILs could also promote the diffusion process of CO_(2)in ***'s to say,the MBILs can enhance the CO_(2)absorption capacity and the diffusive ability *** on the analysis of structural,energetic and dynamical properties,the CO_(2)absorption capacity of MBILs increases in the order Cl^-→[ZnCl_(4)]^(2-)→[CuCl_(4)]^(2-)→[CrCl_(4)]^-→[FeCl_(4)]^-,revealing the fact that the short metal–Cl bond length and small anion volume could facilitate the performance of CO_(2)absorbing *** findings show that the metal–Cl bond length and effective volume of the anion can be the effective factors to regulate the CO_(2)absorption process,which can also shed light on the rational molecular design of MBILs for CO_(2)capture and other key chemical engineering processes,such as IL-based gas sensors,nano-electrical devices and so on.

Dear Editor,Recently,liquid-liquid phase separation(LLPS)attracts great interest for its ability to achieve spatial separation and effective organization of macromolecules(Gomes and Shorter,2018).It is believed to be the driving force to form membraneless organelles and thus plays fundamental roles in a large number of biological processes(Shin and Brangwynne,2017).A list of proteins have been identified that could undergo LLPS in vitro and in vivo(Du and Chen,2018).However,the physiological role of LLPS in animals remains largely unknown.
