This research deals with the fundamental issues of novel nanostructured facilitated transport membranes to separate gases that are difficult and costly to perform with traditional technologies. In facilitated transport, the permselectivity to a target component in a mixture is enhanced by selective and reversible complexation with the facilitating agents imbedded in the membrane. The membranes are targeted at 1) olefin/paraffin separation (to replace or complement with the traditional energy-intensive low temperature distillation), 2) O2 enrichment from air (for enhanced combustion), and 3) CO2 capture from flue gas (for greenhouse gas emission control). They are all directly related to Canada's strategic development of innovative technologies in the resource and energy industries.

这项研究涉及新型纳米结构促进传输膜的基本问题，以分离使用传统技术难以实现且成本高昂的气体。在促进传输中，通过与嵌入在膜中的促进剂选择性和可逆络合来增强对混合物中目标组分的渗透选择性。这些膜的目标是1)烯烃/烷烃分离(取代或补充传统的能源密集型低温蒸馏)，2)从空气中浓缩氧气(用于强化燃烧)，以及3)从烟道气中捕获二氧化碳(用于温室气体排放控制)。它们都与加拿大在资源和能源行业创新技术的战略发展直接相关。
