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…
Two-electron two-nucleus effective Hamiltonian and the spin diffusion barrier
Gevin von Witte, Sebastian Kozerke, Matthias Ernst
Dynamic nuclear polarization (DNP) involves a polarization transfer from unpaired electrons to hyperfine coupled nuclei and can increase the sensitivity of nuclear magnetic resonan…
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…
