Radio-Frequency Sweeps at μT Fields for Parahydrogen-Induced Polarization of Biomolecules
Alastair Marshall, Alon Salhov, Martin Gierse +12
Magnetic resonance imaging of C-labeled metabolites enhanced by parahydrogen-induced polarization (PHIP) can enable real-time monitoring of processes within the body. We int…
Hyperpolarized solution-state NMR spectroscopy with optically polarized crystals
Tim R. Eichhorn, Anna J. Parker, Felix Josten +22
Nuclear spin hyperpolarization provides a promising route to overcome the challenges imposed by the limited sensitivity of nuclear magnetic resonance. Here we demonstrate that diss…
Optically-pumped dynamic nuclear hyperpolarization in C enriched diamond
Anna J. Parker, Keunhong Jeong, Claudia E. Avalos +4
We investigate nuclear spin hyperpolarization from nitrogen vacancy centers in isotopically enriched diamonds with C concentrations up to 100%. C enrichment leads to…
Understanding the magnetic resonance spectrum of nitrogen vacancy centers in an ensemble of randomly-oriented nanodiamonds
Keunhong Jeong, Anna J. Parker, Ralph H. Page +3
Nanodiamonds containing nitrogen vacancy (NV-) centers show promise for a number of emerging applications including targeted in vivo imaging and generating nuclear spin hyperpolari…
Room-Temperature in situ Nuclear Spin Hyperpolarization from Optically-Pumped Nitrogen Vacancy Centers in Diamond
Jonathan P. King, Keunhong Jeong, Christophoros C. Vassiliou +5
We report bulk, room-temperature hyperpolarization of 13C nuclear spins observed via high-field nuclear magnetic resonance (NMR). The hyperpolarization is achieved by optical pumpi…
Scaling of transverse nuclear magnetic relaxation due to magnetic nanoparticle aggregation
K. A. Brown, C. C. Vassiliou, D. Issadore +3
The aggregation of superparamagnetic iron oxide (SPIO) nanoparticles decreases the transverse nuclear magnetic resonance (NMR) relaxation time T2 of adjacent water molecules measur…
Effects of electrical charging on the mechanical Q of a fused silica disk
Michael J. Mortonson, Christophoros C. Vassiliou, David J. Ottaway +2
We report on the effects of an electrical charge on mechanical loss of a fused silica disk. A degradation of Q was seen that correlated with charge on the surface of the sample. We…
Mechanical Loss in Tantala/Silica Dielectric Mirror Coatings
Steven D. Penn, Peter H. Sneddon, Helena Armandula +13
Current interferometric gravitational wave detectors use test masses with mirror coatings formed from multiple layers of dielectric materials, most commonly alternating layers of S…
