Prof. Jordi Arbiol graduated in Physics from the Universitat de Barcelona (UB) in 1997, he went on to obtain his PhD (European Doctorate and PhD Extraordinary Award) in 2001 from this same institution in the field of transmission electron microscopy (TEM) applied to nanostructured materials. He was assistant professor at the UB. From 2009 to 2015 he was ICREA Professor and group leader at the Institut de Ciència de Materials de Barcelona (ICMAB-CSIC). He was President of the Spanish Microscopy Society (SME) (2017-2021) and held the position of vice-president from 2013 to 2017, having been a member of its Executive Board (2009-2021). In 2018 he was elected as Member of the Executive Board of the International Federation of Societies for Microscopy (IFSM) (2019-2026).
Since 2015 he has been ICREA Professor and leader of the Advanced Electron Nanoscopy Group at the Catalan Institute of Nanoscience and Nanotechnology (ICN2), CSIC and BIST. He is Scientific Supervisor of the Electron Microscopy Area at ICN2 and BIST, and also at the Electron Microscopy Center at the ALBA Synchrotron (EMCA). He has been one of the founding members of e-DREAM. He received the FWO Commemorative Medal (Flanders Research Foundation) in 2021, the BIST Ignite Award in 2018, the 2014 EU40 Materials Prize by the E-MRS, the 2014 EMS Outstanding Paper Award and was listed in the Top 40 under 40 Power List (2014) by The Analytical Scientist. As of May 2022 he has more than 415 peer-reviewed publications and more than 24700 citations (GoS) with h-index: 88 GoS (76 WoS).

Dr. Raul Arenal received his Ph.D. in Solid State Physics from Univ. Paris-Sud (Orsay, France, 2005) and in 2013, he obtained his Habilitation (HDR) also at this University (now, Paris-Saclay University). He joined the Electron Microscopy Center in Argonne National Lab. (ANL, USA) as post doctoral fellow. In 2007, he became research scientist (Chargé de Recherches) at the CNRS (France; LEM, ONERA-CNRS). From 2010 to 2011, he was visiting scientist (sabbatical position) at the Laboratorio de Microscopias Avanzadas (LMA) at the Instituto de Nanociencia de Aragon (INA) of the Universidad de Zaragoza (Spain). Since 2012, Dr. Arenal is on leave from the CNRS, and he is currently ARAID senior research scientist at the LMA, INMA, CSIC-U. Zaragoza. Since 2018, he is the Director of the TEM area of the LMA-INA. Dr. Arenal has published more than 200 papers in refereed journals (http://www.raularenal.com) and edited one book (Springer).
Arenal’s 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 low dimensional materials based on carbon, boron and nitrogen as well as other nano-structures (in particular, 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
