Dennis, Very interesting. So far, out of two hundred electrolysis experiments, the only one I find with much promise involves nitinol. Looking at the Debye temp of titanium (~ 107C) I think this makes sense with the thermal triggering that I did. I found that the maximum temperature remained elevated for hours after 10 to 30 second pulses with a joule heater in the cell. I replicated it once in the past, but it may be time for me to revisit this.
