Maritta Lira received her bachelor´s and master’s degree at Universidade Federal do Rio Grande do Norte (Brazil). During the bachelor, she worked with tugstates in a lab of nanomaterials for catalytic reactions. In that time, she received a grant to study Chemical Engineering a year and a half at University of Hull (England), where she could work with magnetic inks. During her master she focused in nanomaterials for catalysis and developed a process to obtain a nanocatalyst (molybdenum carbide) from a raw mineral (molybdenum sulfide). After graduation, she decided to continue the research of the materials for renewable energy applications. Currently, she is a PhD student at the Catalonia Institute for Energy Research (IREC).
