Abstract:  Highlights will be given of research that has been done in Professor Harris’ research group over the past fifteen years.  Two projects will be described in greater detail.  The first project involves the reduction and coating of palladium nanoparticles on the surface of the biotemplate, tobacco mosaic virus.  The kinetics of the adsorption and reduction of the palladium ions and growth of the palladium nanoparticles during the hydrothermal process will be presented.  The second project focuses on the drying of sessile and pendant drops that contain a suspension of colloidal to micron-sized particles.  Furthermore, the presentation will discuss the deposition of particles of different sizes near the contact line and the effect of Marangoni flow on the particle deposition.

Bio: Michael “Mike” Harris is the Associate Dean for Engagement and Undergraduate Education, and the Reilly Professor of Chemical Engineering, and Professor of Environmental and Ecological Engineering in the College of Engineering at Purdue University, West Lafayette.  He was a Purdue University Faculty Scholar from 2002 to 2007, served as the Programming Chair and Chair of the ASEE Minority Division (2011-2014); and was named Fellow of AIChE (2009), won the AIChE Grimes Award for Excellence in Chemical Engineering (2005), and the AIChE Minority Affairs Distinguished Service Award (2009).  He is the author of 97 peer-reviewed publications and 11 patents.  He received his BS in Chemical Engineering from Mississippi State University, and both his MS and PhD degrees in Chemical Engineering from the University of Tennessee. Dr. Harris's research is in the areas of nanomaterials, colloids and interfacial phenomena, transport phenomena, particle science and technology, microwave sensing of pharmaceutical powders, solidification of drug/excipient matrices, environmental control technology, and electrodispersion precipitation processes.
