In the second year of this project, we summarized both experimental and theoretical analyses for transport-induced-charge electroosmotic flow in nanopores. We have developed a standard fabrication process for sub-100 nm pore arrays used in our nanofluidic system for ultra-low flow rate measurements (picoliter/second). A computational model considering force, mass and energy conservation equations has been constructed to capture the experimental flow behavior. The research outcome has been published in a peer-reviewed journal (Micromachines). The paper was selected as a feature paper (Editor's choice) in a special issue of Advances in Nanofluidics. We successfully identified that the presence of Joule heating enhances electroosmotic flow in pores due to transport-induced-charge phenomena.
