Nanoengineering of a New Generation Proton Exchange Membrane for Micro Fuel Cells

Moghaddam S., Masel R., Shannon M., University of Illinois at Urbana-Champaign, US

We report development of the first viable silicon-based proton exchange membrane (PEM). This was achieved through self-assembly of 3-mercaptopropyl-trimethoxysilane (MPTMS) molecules inside extremely high aspect ratio torturous silicon nanopores. This development can greatly benefit the [...]

Application of Grid Focusing Methodology to Transport Monte Carlo Model for Ion Channel Simulations

Kathawala G.A., van der Straaten T., Ravaioli U., University of Illinois at Urbana-Champaign, US

Simulation of Ion Channels has long been an outstanding research problem in the biophysical community. Our transport Monte Carlo model BioMOCA is a particle based approach where we treat water implicitly. It has been used [...]

High Order Parametric Resonance and Nonlinear Mechanics of Nanowires: Techniques and Experiments

Yu M-F, Wagner G.J., University of Illinois at Urbana-Champaign, US

We realize parametric resonances in a nanowire mechanical system using an oscillating electric field. The realization of high order parametric mechanical resonance in macroscopic systems is generally difficult due to mechanical energy losses and strict [...]
