Science meets aesthetics The third winning image from the Nano Image Awards 2025, entitled “Triangles in a Triangle,” shows a single triangle of tungsten diselenide on a graphene/silicon carbide (SiC) substrate. The triangle breaks down into triangles within triangles, forming a series of nested facets. The AFM height image (produced in tapping mode) shows the pattern, and the diagonal bands trace the stepped terraces of SiC that guide the triangle’s growth.
