Project description


Wiki Surface is an international collaborative project whose aim is to create the first open access database of rough surfaces from nature and technology. People are invited to contribute to the database by providing images of surfaces acquired using experimental techniques, as well as the corresponding elevation data field (raw x,y,z data in columns). Authors and their publication related to the posted surface will be fully acknowledged. This database will provide useful information for scientists interested in using real surface topologies to understand the role of surface roughness in surface physics (heat and electric transfer, hydrophobicity, etc.), surface chemistry (chemical reactions) and tribology (stress transfer, adhesion, lubrication, etc.).

To contribute, please contact by email: Maria Rosaria Marulli or Jacopo Bonari
