ABSTRACT:
Convective Deposition: Fundamentals and Energy Applications
Convective deposition of nano- and microscale particles is used as a scalable nanomanufacturing platform to fabricate a wide array of surface morphologies. The fundamental mechanism behind self-organization is surface energy driven attraction of particles confined in a thin film of an advancing meniscus. Instead of solely varying surface and colloidal chemistry to control assembly and deposition, this talk will highlight resulting morphology and various instabilities of uni- and bimodal suspensions that occur when altering the thin film properties during deposition. Modes to avoid the formation of stripes, streaks, and cracks will be discussed. Likewise, techniques that make this process more robust, such as addition of nanoparticles and lateral vibration will also be described. Applications include microlens arrays for light emitting diodes (LEDs, OLEDs) and solar cells and membranes for batteries, fuel cells to considerably enhance selective photonic, electronic, or mass transport for various energy and optical applications.
About Prof. Gilchrist:
Dr. James Gilchrist is the Class of 1961 Associate Professor of Chemical Engineering at Lehigh University. Gilchrist directs the Laboratory for Particle Mixing and Self-Organization with research interests spanning various particle technologies including nanoparticle self-assembly, suspension rheology and transport, hemodynamics, microfluidics, chaotic mixing, and granular dynamics. To date, this research program has resulted in over 40 invited lectures and over $3.2M in funding from NSF, DOE, NASA, ACS, and Pennsylvania initiatives. He received his B.S. in Chemical Engineering from Washington University in St. Louis and Ph.D. from Northwestern University. Prior to joining the faculty of Lehigh University in 2004, he was a postdoctoral research associate in the Department of Materials Science and Engineering at University of Illinois. Prior to his current appointment he held the P.C. Rossin Assistant Professorship from 2007-2010 and was a visiting associate in the Department of Chemical Engineering at the California Institute of Technology. He was a ACS Petroleum Research Fund New Investigator grant recipient in 2006, the North American Mixing Forum Young Faculty Award recipient in 2007 and currently directs a NSF Scalable Nanomanufacturing program for self-assembled particle-based coatings.
