ABSTRACT
The Fresnel Method is one of the many recently developed TEM techniques allowing a microscopist to get digital rather than analogue data from an image. The quantitative application of the Method can allow the composition of a flat, edge-on, interface region to be determined to near atomic level spatial accuracy, so it has considerable potential in the study of oxidation reactions. Here we briefly review the principles of the approach and describe a representative range of the qualitative, as well as quantitative, results we are currently obtaining using the Fresnel Method. We then assess some of the critical problems in the study of oxidation which could be practicably tackled in the future.
