EngSurf-Twin is a three-year Horizon 2020 project funded by the European Union Research and Innovation programme under the Grant Agreement number 952289. It is aimed to overcome some of the main challenges in engineered surfaces and films with adoption of functionalised nanostructured materials, functional metal oxide films and surfaces for technological applications and practices, especially concerning the engineered nano-assemblies, metal oxide nanostructure arrays, for advanced chemical sensors’ design and application. The excellence in the field will be achieved by embedding the project coordinator Selcuk University in a network of excellence, which will be provided by the existing strong twinning partners - the Advanced Materials and BioEngineering Research Centre at the Trinity College of Dublin (AMBER) from Ireland and Fondazione Bruno Kessler (FBK) from Italy.
