Difffusion and Transport in Porous Media
The Reimer group has designed and developed pulsed-field gradient diffusion and multidimensional relaxometry methods to assess the transport of small molecules and ions in complex porous media. The dynamics of these species are of fundamental importance to the development of theories for transport, as well as the crafting of new electrochemical systems for energy storage and delivery. Together with Prof. Nitash Balsara, and supported by JCESR, we have implemented electrophoretic NMR, wherein we discern ionic and molecular transport under an applied electrochemical potential to further our fundamental understanding and design of battery electrolytes.
Here is a recent talk by postdoc David Halat about our e-NMR work in battery electrolytes. It is about 20 minutes long.
