Happy Birthday, ChemistryOpen! The front cover sets the stage for a year of celebration as ChemistryOpen, the first society-owned Gold Open Acces title in chemistry, has been launched 10 years ago. A small selection of cover images, past and present, and a “Thank You!” note highlight that this was only possible due to the steady and wonderful support of our authors. Step into the 1st anniversary issue – we are Open for Publishing! More information on 10 years of ChemistryOpen can be found in the Editorial by Editor in Chief Francesca Novara.
