Thermal Properties of Solids at Room and Cryogenic Temperatures

Guglielmo Ventura was professor of Cryogenics and Vacuum Technologies at the University of Florence until he retired in 2013. He is now a cryogenic consultant for INFN, Rome, in the European project LUCIFER. He has collaborated in space, rocket and balloon born experiments (measurement of the Cosmic Background Radiation or CBR) and is now involved in CUORE (Cryogenic Underground Observatory for Rare Events) underground experiments. Mauro Perfetti was born in 1988 in La Spezia (Italy). After his graduation with first class of honors in 2007, he obtained his bachelor’s degree in 2010 and his master’s degree in 2012 in Chemistry, both Summa com Laude. In 2012 he won a position as PhD student in Chemical Sciences in the University of Florence with the supervision of Professor Roberta Sessoli. Despite his young age, he is co-author of many papers published by prestigious journals. His research line, inserted in the field of Molecular Magnetism, is mainly focused on the understanding of the low temperature magnetic behaviour of anisotropic lanthanide-based Single Molecule Magnets and on the electrical and magnetic characterization of new hybrid materials composed by Single Molecule Magnets grafted on Nanoparticles.
