Impurity Tolerant Membranes

We are sorry, this position has been filled.

Membranes are of great importance for a number of clean energy and clean water applications ranging from desalination to water electrolysis and fuels cells. However, membranes can be prone to degradation, fouling, and imperfect control of the transport of species between each side of the membrane. This project seeks to improve the longevity and performance of membranes by developing bilayer membranes containing ultra-thin metal oxide layers that can be used to enhance selective transport and stability of the membrane. This project will be experimental in nature, focusing on the synthesis, characterization, and evaluation of the ultranthin nanomembrane layers and composite bilayer membranes. The goal of the project is to develop new membranes that are durable over long periods of operation, resistant to degradation caused by impurities, and enable enhanced control over selective transport of ionic species. Several different analytical techniques will be employed to evaluate membrane performance and elucidate transport mechanisms in these novel materials. The student will systematically explore the effect of synthesis conditions and operating conditions on the performance of the membranes. Research will be conducted in an interdisciplinary and collaborative environment.
