This project of bilateral cooperation aims at strengthening the collaboration relationship between two leading research entities in the field of materials science in Romania (NIMP) and France (IPCMS), thus contributing to the creation of a European Research Area. The project has two sides: a scientific side, focused on the corellation between the microstrucural and functional properties of new materials for gas sensors, and a learning side, consisting in training and knowledge transfer activities from the French part towards the Romanian partner, consolidating the role of NIMP as an important pole in the field of materials science, nanoscience and nanotechnology in Romania. A scientific project dedicated to the study of the morphological, structural and functional properties of nanostructured materials for gas sensors is presently running at NIMP in the frame of the National Plan for Research, Development and Innovation 2015-2020 (project PN-III-P4-ID-PCE-2016-0529), involving all the researches included in this bilateral project. Therefore, the bilateral project comes to support the running national project, representing a real source of added value both on the scientific and the human resource forming sides, by utilizing advanced investigation techniques (electron tomography, operando TEM/STEM) and developing scientific competences not yet existing in Romania.
