Preface The ISyDMA conference is an international event focused on recent developments in dielectric materials and their applications. It is aimed at PhD students, post-docs, researchers and engineers from public and private research organizations concerned with innovations in advanced dielectric materials for biomedical, biotechnological and industrial applications. The conference is aimed at materials specialists, physicists, chemists, biologists and engineers engaged in fundamental and applied research on dielectric materials and their innovative applications. ISyDMA is open to a large scientific community since it brings together between 150 and 200 researchers and industrialists of 20 to 25 different nationalities. This is the 6th edition, the previous having taken place in Kenitra and Rabat (Morocco) in 2016, in Bucharest (Romania) in 2017, in Beni-Mellal (Morocco) in 2018, in Amman (Jordan) in 2019 and in virtual in 2020 due to the current health context. ISyDMA’6 is organized as conferences, oral communications and poster sessions. Oral presentations will be grouped by thematic session beginning with invited lectures proposed by the scientific committee or chosen among the submitted papers.The works presented during the meeting will be published in the Conference Proceedings by Springer Nature. Due to the success of the ISyDMA’3 Pre-Conference: First Moroccan Spring School on Advanced Materials, in Marrakech, Morocco from 15 to 17 April 2018, and the ISyDMA’4 Pre-Conference School in Irbid, Jordan, from 30 April – 1 May, 2019, we proudly present our call for the ISyDMA’6 Pre-Conference: International Summer School on Advanced Materials for Energy (ISSAME), which is held from 13 to 14 December 2021 in Saint-Omer, France . The scope of this Summer School is to familiarize students with the state of the art in advanced materials for energy. The target audience for the Pre-Conference School is graduate students and junior researchers (PhD students, postdocs). In addition to the scientific program of these two events, the attendees have a chance to discover the beauty of Calais and the Opal Coast with their several historical monuments classified as World Heritage by UNESCO and the numerous port cities full of history and various resorts that offer a wide range of activities . The social program is extraordinary, reflecting the French sense of hospitality and generosity combined with fun, for the participants and their companions. For the ISyDMA’6 committees Pr.
