This map illustrates the particular features of research and development (R&D) of graphene through improved science and patent basemaps and data overlays. Graphene is a two-dimensional material made out of a single layer of carbon atoms. Its special features – including great strength, yet lightness, and electrical and thermal conductivities – were recognized in the 2010 Nobel Prize in physics. This map, created for the 10th iteration of Places & Spaces , represents a unique opportunity to demonstrate the power of science and patent mapping in understanding scientific and technological development activities with an interesting case study. We combine science maps developed by some of us with colleagues [ 1 ] with our new patent mapping method [ 2 ]. We also show that, compared to other patent maps that also use International Patent Classification (IPC) technology categories [ 3 , 4 ], our approach reveals technological relationships that are not well captured by the IPC system.
