This map represents co-authorship of scientific publications in the areas of nanosciences.
There is a collaboration between 2 Functional Urban Areas (FUA) when organisations located within the boundaries of a FUA share authorship of a publication with organisations located in a second FUA.
FUAs (nodes) and collaborations (links) constitute a network. A cluster analysis was realised to identify the type of position of the FUA in their cluster: 'core', 'intermediary' or 'periphery'.
