2nd IMIL continues and consolidates the successful tradition started in Aveiro in June 2009 of holding meetings of the Iberian community of researchers on ionic liquids every two years. The main aim of these meetings is to bring together Iberian specialists ( as well as contributors from other parts of the world) working in this field in order to share our respective knowledge and expertise in the many fiels of research connected to ionic liquids. We aim to create the perfect environmento to bring about fruitful synergies among the Iberian Community in this promising, exciting and rapidly evolving field.The program for 2nd IMIL includes 28 oral and 58 poster presentations. Included among the oral presentations are an opening lecture and four invited plenary lectures regarding the different topics to which the several sessions are devoted: synthesis and extraction, experimental measurements and theoretical and simulation models.
