Key Learning Points
- Bruker is the longstanding leader in instruments, methods and applications for ultrasensitive NMR via the ‘hyperpolarization’ of nuclear spins. This refers generally to a large, non-equilibrium increase in the alignment of nuclear spins with a magnetic field, yielding correspondingly large gains in detection sensitivity for NMR.
- The most widely used and versatile hyperpolarization method to date Low-Temperature Magic Angle Spinning (LT-MAS) Dynamic Nuclear Polarization (DNP) for solid-state NMR. DNP near 100 K provides signal enhancements of 10x to 300x. Combined with ultrastable LT-MAS, typically spinning the sample at frequencies of 8 – 65 kHz, high-quality spectral evaluation is possible on otherwise inaccessible systems, biomolecules (e.g., membrane proteins), small-molecules (e.g., pharmaceuticals) and materials (e.g, Li and Li+ batteries, polymers and nanoporous structures).
- Bruker is the first and, by far, leading producer of commercial instrumentation for solids DNP, now approaching 50 installations worldwide. We will describe the instruments, sample-handling and DNP methods DNP, as well as key selected applications in the noted fields.
Speakers
Jim Kempf, Ph.D
DNP & Hyperpolarizeation Product Development Manager, Bruker BioSpin Billerica, MA, USA
Jim Kempf started work in hyperpolarized NMR during his Ph.D. studies (1994-2000) at Caltech on optically pumped and detected NMR. In 2001, he completed a postdoc at Cornell on force-detected NMR, then in 2004 at Yale on solution-state biomolecular dynamics by NMR. In 2005, Jim joined the Chemistry faculty of at Rensselaer (RPI), leading a research programs in both biomolecular dynamics and novel solids-state NMR methods. In 2012, he moved to Bruker to return his focus to ultrasensitive NMR methods. In 2016, he became Hyperpolarization Product Manager, focused on dissolution DNP and parahydrogen methods, and in 2021 moved into his current position with enhanced focus on solid-state DNP.
Fabien Aussenac, PhD
DNP Applications Manager, Bruker BioSpin
Fabien Aussenac began his NMR career during his Ph.D. research at the University of Bordeaux I after obtaining a Master of organic chemistry from Toulouse III University (France). He received a Ph.D. in biophysics with research focused on structural and dynamical characterization of biomimetic membrane models by solid state NMR. At the end of his Ph.D., Fabien joined Bruker in 2003 and began working as an application scientist in solid state NMR. Since 2012, he is involved in the development of innovative solid state Dynamic Nuclear Polarization applications, working with a 263 GHz DNP spectrometer at Bruker BioSpin, Wissembourg (France).
