abstract: Energy, environment and sustainability are recognized as critical issues that must be solved for human habitat in the future. Although diverse efforts need to be devoted, the development of new materials and systems capable of high-performance molecular separation can contribute significantly to solving these problems. Tae-Hyun Bae’s research has been focused on energy-efficient separation processes, such as adsorptive and membrane separations, used in many energy and environmental technologies. This talk will open with Bae’s recent work on high-performance adsorbents for application in post-combustion carbon dioxide capture, followed with a segment on gas separation membranes containing nanoporous materials. Improving molecular sieving effect and carbon dioxide sorption property are to methods utilized to synthesize high-performance carbon dioxide separation membranes containing metal-organic frameworks. For composite membranes containing zeolites, novel methodologies developed to enhance zeolite/polymer interfacial morphology and thus improve gas separation performance will be presented. Lastly, future research envisioned as “advanced molecular separations for energy and environmental technologies” will be presented. The new materials and separation processes will be developed to address many current issues in energy and environmental technologies.

biosketch: Tae-Hyun Bae received his B.S. (1999), M.S. (2001) and Ph.D. (2006) degrees from the school of biological resources and materials engineering at Seoul National University after studying polymeric membranes and their processes for water treatments. He earned his second Ph.D. (2010) in chemical engineering at Georgia Institute of Technology under the supervision of professor Christopher W. Jones and professor Sankar Nair. His research at Georgia Tech was focused on engineering nanoporous materials for applications in gas separation membranes. Currently, he is a postdoctoral fellow in Jeffrey Long’s research group at UC Berkeley, where he is working on CO2 capture with metal-organic frameworks and other porous materials.
