Imanol Basterretxea studied a degree in Industrial Chemical Engineering at UPV/EHU, focusing on the research and optimization environment of VHP (Vaporized Hydrogen Peroxide) disinfection systems in the pharmaceutical industry as a subject for his GFR. After finishing his studies in this degree, he is currently studying Industrial Electronics and Automatic Engineering at the UPV/EHU, where he is at the end of his stage. Taking advantage of his desire for the branch of research and the duality of his studies, Imanol has the opportunity to join CIC energiGUNE, with the intention of learning and extending his experience in the environment of research processes through his participation in the Master Intership program in the study of Na-air batteries and electron microscopy. Specifically, this project will be focused on the morphological characterization of the discharge products when charge/discharge with different electrolytes.
