The aim of this course is to explain why the subject of kinetics in nanoscale materials is of wide interest today; because of its link to nanotechnology. In recent years, a major development in science and engineering is nanoscience and nanotechnology. At the moment, the research and development on nanoscale materials science for nanotechnology is ubiquitous, for example, the study of silicon, metal, and oxide nanowires. To build the nanowire device hetero-structure of silicide/Si/silicide requires the study of line contact reaction between Si and metal nanowires to form the silicide electrodes. To use Ag nanowire mesh as the transparent conducting electrodes on flexible solar cells requires the study of point contact reaction between two Ag nanowires. What is unique in kinetics in nanoscale materials is the dominant effect of Gibbs-Thomson potential energy, high concentration gradient, large quantity of non-equilibrium vacancies, very few dislocations, yet very high density of nanotwins and grain boundaries.
