This introductory talk will focus on the process of “bridging,” transitioning terres-trial electrochemical technology to applications in planetary exploration, drawing heavily from the author’s practical experiences. The goal is to...
We determine the maximum stable volume of bubbles attached to flat surfaces as a function of contact radius, contact angle, and capillary length. By solving the Young-Laplace equation using a shooting method, we calculate equilibrium bubble shapes and determine when bubbles detach through three distinct modes: necking at the cavity, sideways instability, and spreading followed by necking on the surrounding surface. Our predicted detachment volumes agree well with experimental measurements of electrolytic, boiling, and carbonated bubbles, as well as pendant drops. These results bring together and extend previous analytical estimates and, by symmetry, also apply directly to pendant drops.
We review the central concepts (e.g. conical intersections) of mechanistic non-adiabatic chemistry as well dynamics methods that can be used where more than one potential surface is involved. With the...
Cathode-Vapour-Feed electrolysers are a special type of Proton-Exchange-Membrane cells. While exhibiting various properties making them especially attractive for applications in the spaceflight industry, their performance is limited by the water...
