Communication: Micropatterning of ceramics (with feature sizes down to 2 mu
m in the horizontal and vertical directions) by means of soft, elastomeric
molds in order to produce crack-free samples is reported. Particular atten
tion is paid to the influence of the initial powder particle size. The cavi
ties shown in the Figure were replicated using 45 nm boehmite powder (scale
bar represents 10 mu m).
