In a Nov 26, 2014 comment in the journal Nature Stephen Pennycook and Sergei Kalinin argue that there is a need for electron microscopes with a resolution of 0. 1 Å which is the goal set in 1959 by physicist Richard Feynman. Pennycock and Kalinin propose that it is possible to overcome to obtain this goal by honing aberration-corrector designs, tweaking optics and electronics, and reducing noise. Three-dimensional (3D) maps of atoms would reveal how materials can be improved in important areas of research including solar materials, batteries and fuel cells.
