Giant and Continuous Ionic Current Oscillation Induced by Dynamic Surface Charge Regulation in Cylindrical Mesopores
Hongwen Zhang, Yujie Zhao, Zekun Gong +4
Nanofluidic ionic oscillators based on the dynamic regulation of surface charges hold great promise for neuromorphic computing, biosensing, and ionic circuits. Here, by dynamically…
Electrostatic Gating of Ionic Conductance Through Heterogeneous van der Waals Nanopores
Aaron H. Barajas-Aguilar, Matthew Schiel, Ethan Cao +6
Nanofluidic ionic transistors typically require gate voltages above 1 V and operate only at sub millimolar ionic strengths, limiting their biocompatible applications. We demonstrat…
Modulation of Ionic Current Rectification in Short Unipolar Nanopores
Hongwen Zhang, Long Ma, Di Liu +3
With controlled ionic current rectification (ICR) achieved through a strategically designed non-uniform surface charge distribution, short unipolar nanopores exhibit promising appl…
Ion transport through differently charged nanoporous membranes: from a single nanopore to multi-nanopores
Hongwen Zhang, Bowen Ai, Zekun Gong +3
Nanoporous membranes, leveraging their high-throughput characteristics, have been widely applied in fields such as molecular separation and energy conversion. Due to interpore inte…
