Since the scanning tunneling microscope allows scientists to visualize regions of high electron density and hence infer the position of individual atoms and molecules on the surface of a lattice, STM nowadays has numerous applications in nanoscience, catalysis and surface science.

Here, top international authors in the field of STM and surface science present first–class contributions on this hot topic, bringing the reader up to date with the latest developments in this rapidly advancing field. The focus is on the nanoscale, particularly in relation to catalysis, involving developments in our understanding of the nature of the surfaces of oxides and nanoparticulate materials, as well as adsorption, and includes in–situ studies of catalysis on such model materials.

Of great interest to practitioners of surface science, nanoscience,STM and catalysis.

"The book covers a wide range of aspects of STM studies on catalysis: methodology, instrumentation, experiment, and theory. An index at the end of the book enables readers to promptly locate the content of their interests. The book contains numerous high–resolution STM images, which renders a pleasant reading experience as well as stimulates appreciation of the power of STM. Therefore, I highly recommend that this book have a space on your bookshelf." (Microscopy and Microanalysis, February 2011)

"A very useful addition to your bookshelf . . . Whether you read only the one chapter related to your area or the entire book . . ., you are bound  to learn something new about this unique instrument and its continued impact on nearly every aspect of surface science and nanoscience as well as its ever–increasing contributions toward understanding catalysis."
