We are working to build understanding of selective permeation mechanisms. We have four approaches to explore these mechanisms for how molecules and ions can penetrate and move through a membrane.

Understanding these selective permeation mechanisms will help us create membrane materials capable of sophisticated separation of chemicals in complex mixtures. This gives us fantastic opportunities to engineer highly selective separation of chemicals in a membrane-based process.




  • Interfacial control

    Using the interface between a mixture and the membrane separating its components gives us an opportunity to control how different chemicals in a mixture enter the membrane.

  • Diffusion control

    Influencing the spaces inside membrane materials will affect how different chemicals in a mixture diffuse through the membrane.

  • Solubility control

    Controlling the properties of spaces inside a membrane will change the way each chemical in a mixture interacts with the spaces as the mixture flows through the membrane.

  • Facilitated transport

    Tuning the chemistry of carriers within membranes to provide highly-selective transport of species through a membrane via reversible carrier-species reactions
