We are very sorry to inform the community of INZA that Elio Passaglia, full professor at the University of Modena and Reggio Emilia, passed away. We would like to remember the great contribution that Prof. Passaglia gave to the knowledge of natural zeolites as witnessed by the large literature he produced in his long career. On behalf of the entire zeolite community we would like to express to his family our most sincere condolences.
