ICREA Research Professor at URV (Universitat Rovira i Virgili). Technology & Engineering
|
He graduated in Physics in 1987 from Universitat Autònoma de Barcelona. Until his PhD (1994, Yale University), he worked with Prof. Juan Fernández de la Mora on aerodynamic focusing, inertial impaction, electrospray atomization, and differential mobility analysis. As postdoc with Prof. John B. Fenn at Virginia Commonwealth Univ., he did research on electrospray ionization mass spectrometry. In 1996, he joined Aradigm Corporation (Hayward CA, USA), where he helped develop liquid micro-jet technology for drug delivery by inhalation, and with Prof. Alfonso Gañán-Calvo co-invented the “flow blurring” atomization method. Since joining ICREA and Universitat Rovira i Virgili (URV) in 2004, he has worked on electrohydrodynamic flows, electrospinning, electrospray, and liquid atomization. He is director of the Droplets, intErfaces, and floWs (DEW) research group of the URV.

My current research is focused on the intriguing dynamics of liquid jets and interfaces, and their transformation into useful materials. Liquid interfaces can be stretched into tiny liquid jets, by electric forces or by fluid streams. Depending on the liquid composition, these jets can break up into droplets or remain unbroken. The ensuing droplets or the unbroken jets are templates which are transformed into solid particles, fibers or thin films, with widths and morphologies tailored at the ‘nano scale’. Because these methods are physical in nature, they can be implemented with different chemical compositions, useful in diverse fields of application, like heterogeneous catalysis, non-linear optics, pharmaceutics, and chemical sensing. The ways in which the building blocks of an applied material (fibers, particles, or droplets) are assembled also influence material performance. Therefore, we study also the transport and precipitation of such objects to different substrates.
