Short CV

Luís Mafra. b 1978, is currently a Principal Researcher and Manager of the solid-state NMR facility at CICECO - Aveiro Institute of Materials, University of Aveiro, Portugal. In 2006, he obtained his PhD from University of Caen (Laboratoire de Catalyse et Spectrochimie), France & University of Aveiro, Portugal, working on solid-state NMR spectroscopy. During this period he developed NMR methodologies to study the structure of hybrid materials using 1H high-resolution CRAMPS NMR techniques and methods to observe quadrupolar nuclei. In 2011 he was a Postdoctoral fellow at Max-Planck-Institut für Polymerforschung, Mainz, Germany. Published ca. 80 SCI research papers and 5 book chapters and gave ca. 55 talks and invited talks at conferences. Since 2010, he has been involved in technology transfer and collaborative research with multiple private companies.

Received various honors & awards, including: 2019 - European Research Council (ERC) Consolidator Grant; 2014 - promoted to Principal Researcher under the national “Investigator FCT” competitive program; 2014 - Adjunct Senior Lecturer honorary title, Sydney University (Australia); 2012 - guest scientist, University of Oviedo, (Spain); 2006 - recipient of Celestino da Costa/Jean Perrin prize; 2009 - António Xavier Bruker prize. He is a member of the editorial board of Solid-state NMR (Elsevier) and regular reviewer of projects from governmental funding agencies of multiple countries.

Scientific Interests

My research interests include the combination of advanced solid‐state (SSNMR) techniques with computational methods to study crystal packing interactions in small molecule powdered pharmaceuticals, and acidity in microporous materials (mostly zeolites) relevant for heterogeneous catalysis. Over the last years, I became interested in studying modified (porous) silica chemisorbents relevant for post- and pre-combustion CO2 capture applications. My main interest lies in the tandem use of SSNMR methods and modeling to study CO2 speciation at material’s surfaces using labeled gases containing NMR‐friendly isotopes. I try to develop NMR methodologies suitable to study at the atomic scale the CO2-sorption mechanism in a variety of porous sorbents either in pure CO2, binary mixtures or more complex gas compositions of industrial relevance.
