Contribution of electron tomography to development of innovative materials for clean energy systems and aeronautics

Abstract

The development of innovative materials for clean energy systems and aeronautics requires use of modern research methods to characterize the structure on the level from micro- to nanoscale. Modern two-dimensional imaging techniques recently available in electron microscopes allow use of tomographic methods to characterize the structure of materials. Application of modern three dimensional imaging techniques such as electron tomography allows accurate qualitative and quantitative measurement of the structure elements in the micro- and nanoscale. The electron tomography studies have been carried out for three-dimensional visualization and metrology of different materials for clean energy systems and aeronautics. Electron tomography results provided quantitative data about shape, size and distribution of the particles, complementary to those obtained by means of quantitative TEM metallography.
