Electrons are omnipresent and electron-induced processes drive many of the most important processes of life, such as photosynthesis (Roach and Krieger-Liszkay 2014). In this paper,some of the varied applications of electron scattering, and the electron collision cross-sections that are required to model and understand such processes, and have mentioned specific data needs where relevant are discussed. There are many other situations where knowledge of electron scattering processes is required. These include the design of lighting; the development of plasma sources for surgery and dentistry, covered by Fridman and Friedman (2013); the design of hypersonic spacecraft capable of re-entry, as discussed by Celiberto et al. (2014); and in combustion processes, where the removal of electrons by electronegative gases provides a means to extinguish a fire without withdrawing oxygen and is thus used in aircraft to extinguish cabin fires. The study of electron scattering from atoms and molecules has grown rapidly since the Frank and Hertz experiment in 1914 and the first quantum mechanical treatments in the 1930s. The wide range of applications ensures that the study of such processes will be important in times to come. Much of the data required for such applications will necessarily be generated by theoretical methods, as explained in this paper, with benchmarks being provided by a few definitive experiments. In conclusion, we look back and wonder at the long conceptual journey from hydrogen to complex atoms, from the small and the common to large and exotic molecular systems, which include fascinating radicals and metastable species. Larger targets such as biomolecules offer challenges as well as opportunities. Collisions and scattering that we dealt with in the firstfive chapters are essentially micro-level phenomena but micro rules the macro, and that was the guiding principle behind the discourses of this concluding chapter. For, it is the basic knowledge that opens possibilities of potential application in diverse fields of technology today.
