Who are we?  We're a  research group in the chemistry department at Michigan State University led by Dr. Merlin Bruening.  The group currently consists (summer 2013) of nine graduate students and two high school students. 

What do we do?  We develop new thin films for protein purification in porous supports, gas separations, membrane-based water reclamation, purification for MALDI mass spectrometry, and selective catalysis. In some cases, students will spend a month or two in countries such as France and Singapore doing collaborative research. Our graduates move on to a wide range of industrial positions.     

What tools do we use?  We use surface infrared spectroscopy, field-emission scanning electron microscopy, electrochemistry, mass spectrometry, ellipsometry, nanofiltration, and atomic force microscopy.  Whenever possible we try to exploit characterization techniques that don't require ultrahigh vacuum so we can simulate actual conditions.

Overview of membrane work

Our group modifies membranes with thin films for applications such as water softening, protein and peptide purification, and catalysis, including protein digestion.
