Temperature-dependent dynamic nuclear polarization of diamond
Gevin von Witte, Aaron Himmler, Konstantin Tamarov +3
Dynamic nuclear polarization (DNP) can increase nuclear magnetic resonance (NMR) signals by orders of magnitude. DNP in diamond proceeds through different DNP mechanisms with a pos…
The role of nuclear spin diffusion in dynamic nuclear polarization of crystalline nanoscale silicon particles
Gevin von Witte, Konstantin Tamarov, Neva Sahin +7
Hyperpolarized nanoparticles (NPs) offer high polarization levels with room temperature relaxation times exceeding half an hour. In this work, we demonstrate that the achievable hy…
Controlled synthesis and characterization of porous silicon nanoparticles for dynamic nuclear polarization
Gevin von Witte, Aaron Himmler, Viivi Hyppönen +9
Si nanoparticles (NPs) have been actively developed as a hyperpolarized magnetic resonance imaging (MRI) contrast agent with an imaging window close to one hour. However, the progr…
Relaxation enhancement by microwave irradiation may limit dynamic nuclear polarization
Gevin von Witte, Aaron Himmler, Sebastian Kozerke +1
Dynamic nuclear polarization enables the hyperpolarization of nuclear spins beyond the thermal-equilibrium Boltzmann distribution. However, it is often unclear why the experimental…
