Gating of Gigantic Ionic Current through Single-Walled Carbon Nanotubes

P. Krstic, and J. Park
Oak Ridge National Laboratory
Oak Ridge, TN

The gigantic magnitude features of the ionic current of electrolyte through carbon nanotubes (CNT) are explained by the dramatic increase of electroosmotic current induced by the strong slip at the CNT surface and the considerable excess volume charge inside the tube. In this study, we investigate the fundamental details of gating phenomena of such gigantic ionic current through CNT by using ...

Previous studies have determined that bridges radiate acoustic energy in the infrasonic frequency range. Initial interest in this topic was the result of trying to identify sources of infrasound recorded at stations deployed near bridges. A Finite Element model has been developed for a Pratt truss railroad bridge located at Ft. Leonard Wood, MO. The model consists of 3-D Euler beam elements ...
