Microtornadoes and Oscillations in Vapor-to-Particle Reaction Zones

Microtornadoes and Oscillations in Vapor-to-Particle Reaction Zones

Series: Modeling and Computation Seminar
Location: Math 402
Presenter: Patrick Shipman, Department of Mathematics, Colorado State University

In topochemically organized, nanoparticulate experimental systems, vapor diffuses and convects to form spatially defined reaction zones. In these zones, a complex sequence of catalyzed proton-transfer, nucleation, growth, aggregation, hydration, charging processes, and turbulence produce rings, tubes, spirals, pulsing crystals, oscillating fronts and patterns such as Liesegang rings. We call these beautiful 3-dimensional structures “microtornadoes”, “microstalagtites”, and “microhurricanes” and make progress towards understanding the mechanisms of their formation with the aid of mathematical models.
