Figure shows the transformation from the precursor molecule to the atomically-precise circumcoronene superlattice. (a) The precursor molecule undergoes a cyclodehydrogenation chemical process with the use of copper (111) substrate which forms the circumcoronene. (b) High-resolution image of the circumcoronene superlattice obtained by using a non-contact atomic force microscopy with a cobalt tip. (c) Schematic...

Hexbyte Glen Cove On-surface synthesis of graphene nanoribbons could advance quantum devices
Scientists synthesized graphene nanoribbons, shown in yellow, on a titanium dioxide substrate, in blue. The lighter ends of the ribbon show magnetic states. The inset drawing shows how the ends have up and down spin, suitable for creating qubits.
