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…
