P.I. Larriba’s field broad spectra could be englobed under a single concept: Nanoengineering and Nanomanufacturing. Among multiple fields, his main focus is steered towards electrosprays of ionic liquids under vacuum (used in clean electrical propulsion for satellites), dielectric electrosprays by means of charge injection atomization (for efficient production and control of fuel drop generation and combustion), Ion Mobility Spectrometry (IMS) coupled with Mass Spectrometry (MS) for the characterization of polymers, nanoparticles and large biomolecules, plasma reactors and plasma modeling for the nucleation and collection of silane ions and nanoparticles.
