Upscaling the hyperpolarization sample volume of an automated hydrogenative parahydrogen-induced polarizer
Yenal Gökpek, Jan-Bernd Hövener, Andrey N. Pravdivtsev
Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) suffer from inherently low sensitivity due to the weak thermal polarization of nuclear spins. Parahydrogen-ind…

Compact magnetic field cycling system with the range from nT to 9.4 T exemplified with 13C relaxation dispersion and SABRE-SHEATH hyperpolarization
Josh P. Peters, Charbel D. Assaf, Jan-Bernd Hövener +1
We present a compact magnetic field cycling system for high-resolution NMR spectrometers. The system enables the transfer of the sample from B0 field of 9.4 T to about nT and all f…
