text: For many years, alongside scientific research, he has carried out an intense dissemination activity, also on the relationship between science and society and between science and peace, with particular reference to energy and resource issues. He is convinced that scientists have a great responsibility that derives from their knowledge and therefore it is their duty to actively contribute to solving the problems of humanity, particularly those connected to the current energy-climate crisis. Every year he holds dozens of seminars in primary or secondary schools and public conferences to illustrate to students and citizens the problems created by the use of fossil fuels: climate change, ecological unsustainability and the social unease deriving from growing inequalities. He believes that three transitions are necessary: from fossil fuels to renewable energies, from the linear economy to the circular economy and from consumerism to sobriety. On these themes he is coauthor of books much appreciated by students and teachers of secondary schools: Chimica (2000); Energia oggi e domani: Prospettive, sfide, speranze (2004); Energia per lastronave Terra (2017), whose first edition (2007) won the Galileo award for scientific dissemination; Chimica! Leggere e scrivere il libro della natura (2012), english version: Chemistry! Reading and writing the book of Nature (2014); Energia, risorse, ambiente (2014); Le macchine molecolari' (2018), finalist in the National Award for Scientific Dissemination Giancarlo Dosi.
