  8. >> General scope - ICREA proposal • Development of aerosol techniques for the generation of nano-structured materials, with emphasis on EHD micro-flows. • Nano-structured fibrous materials by electro-spinning (ESP) • Colloid thrusters for micro-satellites • Electro-hydrodynamics, Electro-hydrodynamic instability of liquids, Rayleigh breakup of droplets, Electrospray ion formation

  9. >> Marie Curie Int’l Grant Nano-electro-hydrodynamic flows generating droplets • Projecte europeu • En vies de co-finançament • Inicia la recerca a Catalunya en aquest camp • Mètodes: • experimentals (mesures de ogtes) COMBINATS AMB la computació d’aquests “nano-fluxos” invisibles
