[NMR] Two PhD positions in Solid State NMR in Nijmegen #DNPNMR #HYPERPOLARIZATION

From the Ampere Magnetic Resonance List



Two PhD positions supported by the Dutch science foundation NWO-COAST and by the Netherlands’ Nuclear Magnetic Resonance graduate school NMARRS are available in the department for solid state NMR at the Radboud University in Nijmegen, The Netherlands under the supervision of Prof. Arno Kentgens and dr. Jan van Bentum.

1) Supercritical chromatography hyphenated with hyperpolarized NMR

In our group we develop methods for high sensitivity on-chip NMR detection of mass-limited samples. This flow system allows flexible operation, including high pressures and supercritical solvents such as CO2. In conjunction with a supercritical chromatography this may provide a fast analytical tool to study complex mixtures with superior information content. One of the advantages of supercritical solvents is the fact that fast mobility can lead to efficient liquid state (Overhauser) Dynamic Nuclear Polarization at relatively high magnetic fields. At present a Gyrotron mm-wave source operating at 395 GHz is available for this purpose, coupled to a 600 MHz NMR spectrometer.

2) Low temperature micro-MAS DNP for materials research

Using micro-coil NMR it is possible to generate ultra-high RF fields, combined with an exquisite sensitivity for small sample volumes. A sustained proton decoupling at RF fields of about 1 MHz can help to obtain unprecedented high resolution in the solid state. A combination with low temperature (10-40 K) sample spinning, and including MAS-DNP at 395 GHz, can help to boost sensitivity to study low concentration sites for example at catalytic surfaces. Our main goal is to optimize the DNP-NMR methodology for quadrupolar nuclei.


For both projects we are looking for enthusiastic candidates with a solid background in NMR and with an affinity for ‘out of the box’ methodology development. We offer a stimulating and exciting environment with state of the art NMR spectrometers up to 850 MHz.
