Method for locally thinning a specimen at the center. Schematic illustrations of the method (a) and images of a specimen before compression (b), after 40% compression (c), after freezing and removal of an aluminum plate (d), and after slicing and thawing (e). A boss is evident in the frozen specimen (arrow in d). The dark spot at the center indicates successful local thinning of the specimen (arrow in e).
