Topical Issue in honor of Ivano Bertini

It is a real pleasure for us to introduce this special issue of JBIC dedicated to Ivano Bertini, which has been realized thanks to the initiative of the Editor-in-chief Larry Que. The two of us helped in the organization of the issue which, as it can be seen, gathers a number of stimulating contributions, either as research articles or reviews, covering many aspects and topics relevant to the field of Biological Inorganic Chemistry.
