CIC energiGUNE is seeking an experienced person to work in an ambitious and novel project which main goal will be to develop by rational design new and suitable ionic liquids (ILs) and organic ionic crystal plastics (OICPs) to be employed in the field of energy storage. Feedstocks such as, amino acids, sugars will be used in the synthesis of both room temperature ILs and IOPs to gain in sustainability. The prepared ILs and OICPs will be tested as phase change materials (PCMs) in thermal energy storage at low temperature for both domestic and industrial applications. Furthermore, a full testing and characterization of the obtained ionic materials will be performed to understand in deep the relationship between their composition/structure and their performance in the selected applications. The full characterization expected to allow “a la carte” design of these materials for a specific application.
