A theoretical understanding of ionic current through a nanochannel driven by a viscosity gradient
Amer Alizadeh, Hirofumi Daiguji, Anne M. Benneker
It has been recently shown that a viscosity gradient could drive electrical current through a negatively charged nanochannel (Wiener and Stein, arXiv: 1807.09106). To understand th…
Transport-Induced-Charge Electroosmosis
Wei-Lun Hsu, Zhixuan Wang, Hirofumi Daiguji
We report theoretical analysis of transport-induced-charge electroosmosis (TICEO) in a nanopore due to the presence of a local electric field and a conductivity gradient. TICEO sha…
Evaluation of gas permeability in porous separators for polymer electrolyte fuel cells: CFD simulation based on micro X-ray computed tomography images
Soichiro Shimotori, Toshihiro Kaneko, Yuta Yoshimoto +4
Pore structures and gas transport properties in porous separators for polymer electrolyte fuel cells are evaluated both experimentally and through simulations. In the experiments,…
Single-Bubble Dynamics in Nanopores: Transition Between Homogeneous and Heterogeneous Nucleation
Soumyadeep Paul, Wei-Lun Hsu, Mirco Magnini +4
When applying a voltage bias across a thin nanopore, localized Joule heating can lead to single bubble nucleation, offering a unique platform for studying nanoscale bubble behavior…
