Monte Carlo simulation of adsorption/desoprption between

1. Computer simulations of Bromine adsorption and diffusion on a Silver electrodePer Arne Rikvold, Florida State University, DMR-9981815 and DMR-0240078 Electrochemistry contributes to society in many ways, including metal production, corrosion protection, and electroplating. Full mastery of these methods requires detailed understanding of the structure and dynamics of the electrode-electrolyte interface. Here we show results of dynamic simulations of Bromine ions adsorbing and diffusing on a Silver electrode. The corrugation potential representing the electrode is based on ab-initio density-functional theory (DFT) calculations. S.J. Mitchell, S. Wang, and P.A.R., Faraday Discussions121, 53 (2002). Monte Carlo simulation of adsorption/desoprption between the fluid (top layer) and the surface (bottom layer). Langevin (stochastic differential-equation) simulation of Bromine ions diffusing on the Silver surface.

2. Computer simulations of Bromine adsorption and diffusion on a Silver electrodePer Arne Rikvold, Florida State University, DMR-9981815 and DMR-0240078 Outreach: With graduate student Mitchell, the PI experimented with LEGO construction toys in elementary and middle-school education. He maintains the general-interest web site http://www.physics.fsu.edu/users/rikvold/info/legostuff.html The PI’s single-cylinder compressed-air LEGO engine. Click button for Quick-time movie. Education: Four undergraduates (Christina J. White Oberlin, Daniel E. Roberts, Shawn Havery, and Philip L. Coltharp), three graduate students (Steven J. Mitchell, Ibrahim Abou-Hamad, and Volkan Sevim), and two postdocs (Gregory Brown and Sanwu Wang) contributed to this work. White Oberlin and Roberts received Goldwater Scholarships, and White Oberlin is an NSF Graduate Fellow for 2002-05. Coltharp, Roberts, and White Oberlin entered graduate school in 2002. Mitchell received his Ph.D. in 2001 and is presently a postdoc at Eindhoven University of Technology in The Netherlands.
