Summary

Surface science has evolved beyond being a sub-field of chemistry or physics and has now become an underpinning science. The Third Edition of this book incorporates extensive worked solutions, as well as details on how problem solving relevant to surface science should be performed. It contextualizes the exercises and their solutions to further explicate the methods of problem solving, application of scientific principles and to deliver a deeper understanding of the field of surface science. Solutions will be accompanied by figures and/or graphs of data, as appropriate.
