It has been a fantastic week of talks and discussions about how materials science and technology can contribute to a more sustainable world in the MATSUS 2025 Spring Meeting held in Seville. Our group (https://lnkd.in/dDaXDgxx) has contributed to this vibrant environment with seven talks in simposia PeroLight, PerFut25, Simusoled, PeroQuant and PhotoPero.
