Polarisation Dynamique Nucléaire à Ultra Basse Température et haute fréquence MAS Au cours des 10 dernières années, notre équipe a conduit des développements instrumentaux et méthodologiques majeurs permettant de réaliser des expériences de polarisation dynamique nucléaire (DNP) avec des agents polarisants beaucoup plus efficaces (deux brevets déposés), et d’accéder à une plage de température entre … Read more

Materials and surface studies Another part of our research activity has been dedicated to the study of complex systems that cannot be tackled fully by other atomic level characterization techniques. Notably, we have investigated the structure of various types of materials (from catalytic surfaces to functionalized silica nanoparticles and bacterial cell walls) and thanks to … Read more
Theory of MAS DNP Even if the discovery of DNP (at 0.003 T) is not exactly recent, the (deep and correct) understanding of the mechanisms at work during polarization transfer at high magnetic field under (rapid) sample spinning is not fully achieved yet. It is thus essential to carry out work in this direction with the goal … Read more
