Waldemar A. Marmisollé was born in Junín (Buenos Aires, Argentina) in 1984. He studied chemistry at the Universidad Nacional de La Plata (UNLP) receiving his degree in 2007 and his PhD in chemistry in 2011. He performed post-doctoral work at the Universidad de Buenos Aires (UBA) and he is now  Professor of Physical Chemistry at UNLP and fellow member of CONICET working at the Soft Matter Laboratory at INIFTA. He has published more than seventy papers in international journals. He also has published five chapters of books.His research interests include conducting polymers and soft matter electrochemistry.Prof. Dionisio Posadas was born in San Juan, Argentina in 1943. He studied chemistry at the Universidad Nacional de La Plata (UNLP). There he obtained his degree at 1966 and his PhD in 1969. He was postdoctoral fellow at the Chemistry Department of Southampton University, Great Britain during 1972-.73. He was visiting Professor at the Chemistry Department, Case- Western Reserve University, Cleveland, Ohio, EEUU, three months, 1981, and at several universities in France, Spain and Brazil. Invited to oral presentations several times at the ISE meetings and at International Workshop on the Electrochemistry of Electroactive Materials. He was full Professor of Chemical Physics  at the Faculty  of Exact Sciences at the National University of Buenos Aires, also, at different times, Full Professor of Physical Chemistry at the Faculty  of Exact Sciences at the National University of La Plata. He has published more than a hundred papers in international journals of Electrochemistry and Physical Chemistry. Also he has published several chapters in books and two books (in Spanish). He is emeritus Professor of the UNLP and fellow research of CONICET (under contract). His research interests include physical chemistry properties of Redox Polymers.
