Electrochemically Driven Transport in Nanopores and Membranes

H. White
University of Utah

In this presentation we outline the analysis methods applicable to the electrochemical driven transport in nanopores and membranes. This is a modern and ever growing research area with many different applications, some examples are:

• iontophoretic drug delivery across skin, • protein ion channel based sensors, • resistive pulse counting of nanoparticles, • 3-D microbattery design, • transport in ordered synthetic membranes.

In this presentation we present as a specific case study, numerical simulations of 3D Microbatteries. The development of small electric devices have always struggled with the problem of powering them with equally small batteries.

The purpose of the current research is to develop microbatteries capable of powering MEMS devices.

Keynote speaker's biography: Henry White is a Professor in the Department of Chemistry at the University of Utah. He received his B.S. degree in chemistry from the University of North Carolina (1978) and Ph.D. degree in chemistry from the University of Texas (1983). Following a postdoctoral appointment at MIT, he was on the faculty of chemical engineering and materials science at the University of Minnesota (1984-93).

Professor White’s research spans experimental and fundamental electrochemistry. Current research includes molecular transport in ultra thin-layer electrochemical cells, three-dimensional microbatteries, the nanopore electrode sensor, electrochemical particle counting, electric field-assisted transdermal drug delivery, and magnetoelectrochemistry.

He is the recipient of the Reilley Award of the Society of Electroanalytical Chemistry (2000), the Faraday Medal from the Electrochemistry Group of the Royal Society of Chemistry, (2002), the ACS Analytical Division Award in Electrochemistry (2004), the Grahame Award in Physical Electrochemistry from The Electrochemical Society (2005), and the Distinguished Creative Research Award (2004) at the University of Utah. He is an Associate Editor of the Journal of the American Chemical Society.

H. White was one of the keynote speakers at the COMSOL User's Conference, fall 2006 in Las Vegas.
