New advance in the preparation of giant nanographs

Researchers from the BERC POLYMAT and the UPV/EHU, in collaboration with researchers from the University of Aveiro and the University of Osaka, have developed a methodology to prepare star-shaped giant nanographs. This scientific achievement has been published in the prestigious German magazine Angewandte Chemie as "hot paper" for its relevance.

Nanographs are nano-sized structures cut from a sheet of graphene. The shape and size of these graphene cuts dominate their properties and therefore it is essential to develop methodologies that allow controlling the structure with atomic precision and, that at the same time, allow to prepare structures large enough to exploit their properties.

The nanostars synthesized in this work are the largest synthesized with atomic precision, and have the necessary dimensions for the preparation of electronic devices consisting of a single nano-star. This has important applications in fields such as electronics, photonics, and energy transformation and storage.
