Handbook of Heterogenous Kinetics

Michel SOUSTELLE is a chemical engineer and Emeritus Professor at Ecole des Mines de Saint-Etienne in France. He taught chemical kinetics from postgraduate to master's degree level while also carrying out research in this topic.

"Soustelle (emeritus, heterogenous kinetics, Ecole Nationale Supérieure des Mines, France) offers an extensive overview of the theoretical and experimental basis of heterogenous kinetics and its application to the study of solids reactivity. The field integrates physical, theoretical, and computational elements of chemistry and materials science. The book's contents are based on courses given for undergraduates and master's students in chemical engineering." (Book News, September 2010)
