Development of MPI relaxometer for characterization of superparamagnetic nanoparticles
Abstract This paper presents the design, implementation, and experimental measurements of a custom-made MPI relaxometer to characterize superparamagnetic iron oxide nanoparticles (SPIONs) as a tracer for Magnetic Particle Imaging (MPI). The relaxometer is electromagnetic interference (EMI) shielded and serves as a zero magnetic field MPI scanner at 4.

Dose-Dependent Effects of Biochar on Soil Revealed by Fast Field-Cycling (FFC) NMR: From Molecular Water Dynamics to Soil Functionality. [PDF]
Dose–response of biochar in a clay soil: fifteen mixtures (fBC 0–1) reveal nonlinear thresholds (pH/EC) and sharp WHC gains near fBC ≈ 0.3–0.5. Coupled FT‐IR and FFC‐NMR (0.01–10 MHz; ModelFree τc distributions) link water dynamics to soil functionality.

Mn<sup>2+</sup> Complex of a Fluorinated CDTA-Derivative: Stability, Inertness, and Paramagnetic <sup>1</sup>H, <sup>17</sup>O, and <sup>19</sup>F Relaxation Properties. [PDF]
The fluorinated CDTA‐bisamide derivative ligand, L2, forms a stable and highly inert complex with Mn2+. MnL2 has one inner sphere water coordinated to the central metal ion, hence good proton relaxivity, and the paramagnetic metal ion induces important acceleration of 19F relaxation, provides good signal‐to‐noise ratios on 19F phantom UTE MR images ...
