It was a great opportunity to have been able to transmit the research of excellence in science and materials engineering to all those attending the Fair. Helping to awaken the interest to solve the challenges of society and promote sustainable development in Madrid. Researchers from IMDEA Materials showed the importance of studying new materials, how to improve current ones through new additives or novel manufacturing processes, as well as their study by computational calculations. All this for applications in various fields, from aeronautics to biomaterials. Experiments, demonstrators and videos were shown on the main R & D activities in IMDEA Materials.
