From the 15th to 18th of October, Luca Gerhards and Ilia Solov'yov are taking part in the conference for Collisions Physics and Chemistry and their Applications (COPCA) in Valetta, Malta. The COPCA conference brings together scientific researchers from several interdisciplinary fields to share their research and results. This year, a particular focus will be placed on processes relevant to radiation chemistry and physics, astrophysics and astrochemistry, and materials science. The conference will take place alongside a thematically-related workshop of the COST Action CA20129 "Multiscale Irradiation and Chemistry-Driven Processes and Related Technologies" (MultIChem). Ilia is giving an invited talk about "Modelling Collision Processes in Complex Molecular Systems Using VIKING".
