This article describes the novel use and implementation of high speed video-based characterization of the activity and stability of electrocatalysts based on the rate and size of  the bubbles associated with evolved gas.  The general approach is highly parallel and...

This article describes the construction and use of a novel instrument, the scanning droplet cell, to quantify the electrocatalysts millions of times more rapidly than alternative methods.  The utility of the scanning droplet cell is also demonstrated in evaluating...
