Textbook in PDF format Surfaces are involved in many important chemical and biological processes in nature and in industry largely because of their high chemical reactivity. Surface chemistry is important in many critical chemical processes, such as enzymatic reactions at biological interfaces found in cell walls and membranes, in electronics at the surfaces and interfaces of microchips used in computers, and the heterogeneous catalysts found in the catalytic converter used for cleaning processes. This book covers major areas of modern Surface Science which is a broad area at the intersection of Chemistry and Physics
