self-assembled nanoscale structures

Caption

Layering block copolymers and heating them for different times resulted in a range of exotic nanoscale structures (scale bar is 100 nanometers). This image shows scanning electron micrographs and cartoon representations of parapets (cylinders on top and lamellae on bottom), a Swiss-cheese-like patchwork of porous lamellae, and aqueducts (lamellae on top of cylinders). Metals or oxides formed in these shapes could have properties useful for sensors, membranes, transistors, and more.
