Dr. Raul Arenal received his Ph.D. in Solid State Physics from U. Paris-Sud (France, 2005) and in 2013, he obtained his Habilitation (HDR) also at this University. In 2005, he joined Argonne National Laboratory (USA) as post doctoral fellow. In 2007, he became research scientist (Chargé de Recherches) at the CNRS (France). From Sept. 2010 to Dec. 2011, he was visiting scientist at the Lab. de Microscopias Avanzadas (LMA) at the Inst. de Nanociencia de Aragon (INA) of the U. Zaragoza (Spain). Since 2012, Dr. Arenal is on leave from the CNRS, and he is currently ARAID research scientist at the LMA-INA-U. Zaragoza. Since 2018, he is the Director of the TEM area of the LMA-INA. He has published > 160 papers, edited 1 book and published 6 chapters of a book. In 2017, Dr. Arenal has been elected member of the Young Academy of Europe (YAE) and he has been elected at the board of the YAE. His broad area of research interest lies in electron microscopy focused on materials science and nanoscience: TEM (EELS, HR(S)TEM, electron diffraction, electron tomography). These studies are mainly focused on the growth mechanism, structural and physical properties of nanomaterials based on carbon, boron and nitrogen as well as other nano-structures (as metallic nano-objects for plasmonic/photonic interest). Among his scientific activities, Dr. Arenal is the chair of the HeteroNanoCarb conference series (http://heteronanocarb.org) focused on graphene, NT and related 1D-2D nanomaterials.
