Seminar - “pH-Controlled Complex Formation in Charged Polymer Systems” by Kenneth R. Shull, Department of Materials Science and Engineering, Northwestern University, Evanston, IL USA
ABSTRACT: Complexes formed in systems containing both positive and negative charges are of fundamental importance in a variety of materials applications. A common method for producing polyelectrolyte complex films is to sequentially deposit oppositely charged polymers, an effective but tedious process that is not readily scalable. A focus on this talk is on the deposition of relatively thick films directly onto conducting surfaces, using electrochemical processes to modulate the local pH. The process is carried out on a quartz crystal microbalance, which in addition to
We are pleased to introduce Professor Evelyn Yim to the Department of Chemical Engineering. Her research interests include nanofabrication technologies and stem cell culture. Evelyn’s work on stem cells, nanofabrication and biomaterials supports the advancement of healthcare technologies to repair, replace or regenerate damaged tissue and organ structures.
