They were welcomed by Prof. Raquel Ibáñez who gave them some tips about the role of the Chemical Engineerings in the professional world, and after that they visited the teaching and research laboratories, where they had the opportunity of speaking with some researchers that explained to them the scientific works in which they are currently involved.
