Arantxa Arbe

The scientific carrier of Arantxa Arbe (Research Professor of the Spanish National Research Council, CSIC, since 2009) has been closely linked to the Group of Polymers and Soft Matter in San Sebastian (Spain). There she carried out her PhD (1990-1994), under the supervision of Prof. Colmenero, combining dielectric spectroscopy with neutron scattering techniques for the investigation of the dynamics of linear homopolymers. In her post-doctoral stay in the Forschungszentrum Jülich (Germany) (1994-1996), she acquired a solid background in the use of scattering techniques. Her achievements during that period were recognized with the Young Scientists Award of the European Neutron Scattering Association (1996). Later, she translated her experience to the San Sebastian group, in which she integrated as responsible for the application of scattering techniques (neutrons and X-rays). These methods constitute one of the main pillars of the well-known methodology developed in this group, that combines experimental techniques (relaxation, calorimetry, microscopy and scattering) and computer simulations (coarse grained and fully atomistic). Along her carrier, she has investigated structural and dynamical properties of soft matter systems based on polymers of increasing complexity (homopolymers, polymer blends, solutions, nano-composites, nano-structured materials, systems containing polymeric single-chain nano-particles, etc). In particular, by applying quasielastic neutron scattering techniques she has gained deep insight on different dynamical processes taking place in these systems at different length scales (like side-group motions, segmental relaxation, Rouse-like dynamics, reptation).
