Piran R. Kidambi, Ph.D., Harrington Faculty Fellow at The University of Texas at Austin and Assistant Professor of Chemical and Biomolecular Engineering, Mechanical Engineering at Vanderbilt University (on-leave) will present, "Nanoscale Mass Transport in 2D and 1D Nanomaterials for Energy, Environment and Healthcare". Friday, March 7, 2024, 1-2PM CDT in EER 3.646 or by Zoom 828 685 7838.
Abstract
2D and 1D nanomaterials offer fundamentally new opportunities to study, understand and control mass transport at the sub-nanometer-scale. Specifically, they allow for quantum tunneling and size-selective ionic/molecular transport/sieving. I will discuss our recent work in 2D material synthesis and processing to enable i) large-area atomically thin Helium barriers, ii) fully functional nanoporous atomically thin membranes for desalination, dialysis, and molecular separations, iii) bottom-up formation of nanopores in 2D lattices, iv) new approaches to probe sub-nanometer scale defects in centimeter scale 2D-single-crystals, v) size-selective defect sealing for functional large-area 2D membranes, vi) roll-to-roll manufacturing of atomically thin membranes, and vii) proton transport through atomically thin membranes for advancing energy conversion/storage and security. Finally, I will discuss transport in 1D nanomaterials (carbon nanotubes) for hemodialysis as well as some of our efforts to move these technologies to the commercial arena.
