Flexible, scalable and cost-effective manufacturing of nano-enabled devices will require modular processes or unit operations that can be arranged in specific process flows for different devices. Like chemical plants, these nanomanufacturing facilities will be composed of unit operations that include 3D patterning and nanosculpting, direct nanoscale deposition of functional materials, transfer of nanometer and atomically thin films, and directed self-assembly of nanoparticles and structured polymers, among other processes. I will discuss the needs and opportunities for modeling and simulating them in silico to mitigate risk and lower cost before construction of a production facility. To illustrate the power of the unit operation concept coupled with simulation for the development and evaluation of nanomanufacturing systems, I will also present detailed results on tools for: 1) UV imprint lithography; 2) directed self-assembly of spherical and rectangular particles for bit patterned magnetic-media; and 3) roll-to-roll transfer of 2D materials, such as graphene. 


Speaker's Bio:

Dr. Roger T. Bonnecaze is the William and Bettye Nowlin Chair of Engineering in the McKetta Department of Chemical Engineering and the co-Director of the NSF Engineering Research Center for Nanomanufacturing Systems for Mobile Computing and Energy Technologies (NASCENT) at The University of Texas at Austin. He received his B.S. (‘85) from Cornell University and his M.S. (‘87) and Ph.D. (‘91) from the California Institute of Technology, all in chemical engineering. Between his M.S. and Ph.D., Dr. Bonnecaze was a project manager for Hydro Research Science working on environmental fluid mechanics and designing and testing hydraulic structures. After his doctorate, Dr. Bonnecaze was a BP Post-Doctoral Fellow at the Department of Applied Mathematics and Theoretical Physics. He joined the faculty at The University of Texas in 1993. Dr. Bonnecaze’s research interests include nanomanufacturing modeling and simulation and the rheology of complex fluids. He has won the NSF Young Investigator Award, David and Lucile Packard Foundation Fellowship, the AIChE Thomas Baron Award, two Journal of Rheology Publication Awards and numerous teaching awards. Dr. Bonnecaze is a Fellow of the American Physical Society, the American Institute of Chemical Engineers and the American Association for the Advancement of Science.
