Short CV

Luís Mafra. b 1978. BSc, 2003, Universidade Nova de Lisboa, Portugal, PhD, 2006, Universidade de Aveiro, Portugal, PhD, 2006, Université de Caen Normandie, France. January–December 2012, guest scientist with a research excellence fellowship, University of Oviedo, Spain (Futtalent program). 2011, invited researcher, Max-Planck-Institut für Polymerforschung, Mainz, Germany. Recipient of Celestino da Costa/Jean Perrin (APDF) and António Xavier (instituted by Bruker) prizes. Since 2007 researcher at CICECO - Aveiro Institute of Materials, University of Aveiro, and manager of the solid-state NMR unit. 2014, promoted to Principal Researcher at CICECO under the national "Investigador FCT" program (classification: 9/9).  He has 12 years of experience in solid-state NMR (SSNMR) spectroscopy and contributed with more than 90 conference communications (including ∼26 talks plus ∼17 invited talks at international conferences and 17 invited oral presentations in research centres overseas). Published about 65 peer-reviewed international publications listed at the SCI (∼40% found in journals with IF > 5) and 4 book chapters related to SSNMR. He is also a member of the editorial board of the solid-state NMR journal (Elsevier) and has been deeply involved in technology transfer, consultancy and collaborative research with multiple private companies.

Scientific Interests

In methodology:
- Development of solid-state NMR methods involving resolution enhancement schemes for 1H observation to record high-resolution 1D/2D NMR spectra using CRAMPS methods combined or not with “ultra-fast” MAS technology (up to 100 kHz);
- Sensitivity enhancement methods for the observation of quadrupolar spins and new methods for more robust heteronuclear recoupling between spin-1/2 and spin>1/2 nuclei;
- Use of the GIPAW-DFT approach to calculate NMR tensors in small molecules.

In applications:
- NMR characterization of extended systems (e.g., inorganic-(bio)organic hybrids, porous materials) relevant in heterogeneous catalysis (NMR study of Lewis and Brønsted acidity) with a particular interest for studying modified nanoporous solid sorbents with potential for gas capture/sorption of gases labeled in key NMR-friendly isotopes (e.g., 13CO2 in a gas mixture mimicking flue gas streams);
- Combining high-resolution 1H solid-state NMR recoupling methods, X-ray diffraction and computational ap- proaches to study crystal packing interactions on pharmaceuticals and materials (NMR crystallography);
- Study drug-drug and drug-host interactions of molecular scaffolds as drug delivery systems.
