Abstract:

Solid-state NMR spectroscopy is the most powerful structural elucidation technique of powdered solids available and provides very detailed structural and dynamics information across both the physical and biological sciences. However, the weak sensitivity of the NMR signals poses major limitation, requiring many hours or days of acquisition time. This prevents the use of solid-state NMR for structure characterization in many areas, in particular the study of advanced functionalized nanomaterials. A powerful and really dramatic approach involves the use of electron as source of polarization to enhance the solid-state NMR signal by multiple orders of magnitude, a technique known as dynamic nuclear polarization (DNP). The talk will describe the use of stable radicals and transition metal high spins ions as the source of electrons, and recent breakthrough in the applications of DNP enhanced solid-state NMR spectroscopy towards the high-throughput structural characterization of a extremely large range of nanomaterials such as polymeric organic nanoporous materials, inorganic materials, hydrogels and metal organic frameworks.

Biography :

Frederic Blanc received his PhD in Chemistry from the University of Lyon (France) in 2008 working on solid-state NMR methods to characterize surfaces and nanomaterials. He was then a Lavoisier postdoctoral fellow at the State University of New York in Stony Brook from 2008 to 2010 and a Marie Curie fellow at the University of Cambridge from 2010 to 2012, and recently joined the faculty of the University of Liverpool as an Assistant Professor/Lecturer in Chemistry. His research interests lie at the frontier of NMR spectroscopy and nanomaterials, and he has published more than 35 papers.
