(Phys.org)—As chemical reactions proceed, the reactants combine to form intermediates and those short-lived intermediates eventually become products. Reaction kinetics is concerned with how long it takes for the reaction ...
Analyzing what happens where interfaces meet and mix is essential toward understanding and controlling fundamental mechanisms in both natural and industrial systems. By considering the reaction front of heterogeneous fluid ...
