Graphene nanoribbons eye role as radiation sensors for fusion reactors
US researchers demonstrate that graphene nanoribbons can survive gamma irradiation with their lattice intact and still produce a measurable electrical signal, enabling GNR-based sensors that could operate closer to a fusion reactor's first wall, improving monitoring and potentially reducing shutdowns; the work used nine-atom-wide armchair GNRs integrated into field-effect transistors and analyzed with Raman spectroscopy after exposure.
