    • Carbon molecular-sieve membranes developed from a Tröger's base polymer and possessing superior gas-separation performance 

      Dai, Zhongde; Guo, Hongfang; Deng, Jing; Deng, Liyuan; Yan, Jiaqi; Spontak, Richard J (Journal article; Peer reviewed, 2023)
      Carbon molecular-sieve membranes possess tremendous practical advantages over unary polymer membranes by providing high gas-separation performance levels, coupled with excellent mechanical and chemical stability. Improving ...

    • Effects of Porous Supports in Thin-Film Composite Membranes on CO<inf>2</inf> Separation Performances 

      Guo, Hongfang; Xu, Wenqi; Wei, Jing; Ma, Yulei; Qin, Zikang; Dai, Zhongde; Deng, Jing; Deng, Liyuan (Peer reviewed; Journal article, 2023)
      Despite numerous publications on membrane materials and the fabrication of thin-film composite (TFC) membranes for CO2 separation in recent decades, the effects of porous supports on TFC membrane performance have rarely ...

    • Helium separation using membrane technology: Recent advances and perspectives 

      Dai, Zhongde; Deng, Jing; He, Xuezhong; Scholes, Colin; Jiang, Xia; Wang, Bangda; Guo, Hongfang; Ma, Yulie; Deng, Liyuan (Peer reviewed; Journal article, 2021)
      Helium is an unrenewable noble gas produced from natural gas with a wide range of scientific, medical, and industrial applications. Due to the large differences in the kinetic diameters between helium (0.26 nm) and nitrogen ...

    • Hydrogen sulfide removal from natural gas using membrane technology: a review 

      Ma, Yulei; Guo, Hongfang; Selyanchyn, Roman; Wang, Bangda; Deng, Liyuan; Dai, Zhongde; Jiang, Xia (Peer reviewed; Journal article, 2021)
      Natural gas, having a significantly lower CO2 emission factor than oil and coal when combusted, is accepted as an important transition fuel towards carbon net-zero society. To meet the calorific value requirements (≥34.0 ...

    • Nanocellulose Crystal-Enhanced Hybrid Membrane for CO2 Capture 

      Dai, Zhongde; Deng, Jing; Ma, Yulei; Guo, Hongfang; Wei, Jing; Wang, Bangda; Jiang, Xia; Deng, Liyuan (Peer reviewed; Journal article, 2022)
      Developing a membrane material with both high CO2 permeability and high CO2/N2 selectivity is always desired for CO2 capture, while improving the sustainability of the membrane preparation process is of equal importance. ...
