Technological and digital innovation are very important drivers in the implementation of a circular economy. In this context, this professional training will focus on describing processes whose methodology has a considerable impact on the acceleration of Materials Science and Engineering. The integrated approach of additive manufacturing, the synthesis and safe integration of nano-objects into devices and cutting edge surface engineering processes will be more specifically studied; the contribution of digital technologies, both for design and development using Artificial Intelligence approaches will also be discussed. Finally, many applications in the low-carbon energy field will be highlighted.
