Rainfall patterns are shifting, populations are growing, and our already-stressed rivers and aquifers are struggling to keep up. Filtering clean water from seawater seems like an obvious alternative, but the steep price tag of desalination plants has hampered widespread construction.

Join us on February 12, 2014 to hear from Daniel Schwartz, Director of the new Clean Energy Institute (CEI). CEI was formed when Gov. Inslee and state legislators allocated $6 million to create a research center at the university that will advance solar energy and electrical energy storage capacities. The Clean Energy Institute is enabling us to dive into the science and engineering that will lead to solar and energy storage technologies the world needs and wants.

Surface patterns were created directly onto a commercial polyethersulfone ultrafiltration membrane using nanoimprint lithography, which resulted in a moderately reduced molecular mass cut-off (MWCO) but similar permeance as its non-imprinted counterpart as well as significantly improved resistance to BSA fouling. Staged filtration experiments, with backwash cleaning, revealed that the permeate flux of the imprinted membrane was considerably higher than that of the non-imprinted membrane, consistent with UV–vis measurements showing less protein deposition on the imprinted membranes.
