| 1 | Engineering HOF‑Based Mixed‑Matrix Membranes for Efficient CO_(2) Separation显示文摘Hydrogen-bonded organic frameworks(HOFs)have emerged as a new class of crystalline porous materials,and their application in membrane technology needs to be explored.Herein,for the first time,we demonstrated the utilization of HOF-based mixed-matrix membrane for CO_(2) separation.HOF-21,a unique metallo-hydrogen-bonded organic framework material,was designed and processed into nanofillers via amine modulator,uniformly dispersing with Pebax polymer.Featured with the mix-bonded framework,HOF-21 possessed moderate pore size of 0.35 nm and displayed excellent stability under humid feed gas.The chemical functions of multiple binding sites and continuous hydrogen-bonded network jointly facilitated the mass transport of CO_(2).The resulting HOF-21 mixed-matrix membrane exhibited a permeability above 750 Barrer,a selectivity of~40 for CO_(2)/CH_(4) and~60 for CO_(2)/N_(2),surpassing the 2008 Robeson upper bound.This work enlarges the family of mixed-matrix membranes and lays the foundation for HOF membrane development. | Yuhan Wang Yanxiong Ren Yu Cao Xu Liang Guangwei He Hanze Ma Hongliang Dong Xiao Fang Fusheng Pan Zhongyi Jiang | 2023 | Nano-Micro Letters2023，15，4： | 2 |

| 3 | Microstructure Manipulation of Covalent Organic Frameworks(COFs)-based Membrane for Efficient Separations显示文摘Covalent organic framework(COF) membranes have exhibited great potential to become the next-generation membranes for efficient separations due to the diverse structures, ordered framework pores, tunable functionality and excellent stability. This review presents the microstructure manipulation strategies for separation performance enhancement of COF membranes in recent years. Based on the three mechanisms of molecular sieving, surface diffusion, and facilitated transport, the structural modulation methods to enhance the selectivity of COF membranes are analyzed in detail. Next, strategies of realizing ultrashort mass transfer pathways and ultralow mass transfer resistance for the permeability enhancement are elaborated. Furthermore, the framework stability in COFs, interlayer stability between COF nanosheets and interfacial stability between COF layer and substrate are discussed. Finally, we discuss the existing challenges and perspectives on the future development of COF membranes, targeting at identifying the most promising strategies and directions for the engineering of COF membranes. | MA Hanze WANG Shaoyu REN Yanxiong LIANG Xu WANG Yuhan ZHU Ziting HE Guangwei JIANG Zhongyi | 2022 | Chemical Research in Chinese Universities2022，38，2： | 0 |
| 4 | Characterizations of umbilic hypersurfaces in warped product manifolds显示文摘We consider the closed orientable hypersurfaces in a wide class of warped product manifolds, which include space forms, deSitter-Schwarzschild and Reissner-Nordström manifolds. By using an integral formula or Brendle’s Heintze-Karcher type inequality, we present some new characterizations of umbilic hypersurfaces. These results can be viewed as generalizations of the classical Jellet-Liebmann theorem and the Alexandrov theorem in Euclidean space. | hanze GAO Hui MA | 2021 | Frontiers of Mathematics in China2021，16，3： | 0 |
