Environmental NMR: Fast-field-cycling Relaxometry [PDF]
, 2013 Fast-field-cycling (FFC) NMR relaxometry deals with the variation of the spin–lattice relaxation times (T1) in a complex system, as the strength of the applied magnetic field is changed. Information about molecular dynamics can be achieved.

Joint multi-field T<sub>1</sub> quantification for fast field-cycling MRI. [PDF]
Magn Reson Med, 2021 PurposeRecent developments in hardware design enable the use of fast field‐cycling (FFC) techniques in MRI to exploit the different relaxation rates at very low field strength, achieving novel contrast. The method opens new avenues for in vivo characterizations of pathologies but at the expense of longer acquisition times.

Fast field-cycling magnetic resonance imaging [PDF]
Comptes Rendus. Physique, 2010 Magnetic resonance imaging (MRI) and fast field-cycling (FFC) NMR are both well-developed methods. The combination of these techniques, namely fast field-cycling magnetic resonance imaging (FFC-MRI) is much less well-known. Nevertheless, FFC-MRI has a number of significant applications and advantages over conventional techniques, and is being pursued ...

High-Field Detection of Biomarkers with Fast Field-Cycling MRI: The Example of Zinc Sensing. [PDF]
Chemistry, 2019 AbstractMany smart magnetic resonance imaging (MRI) probes provide response to a biomarker based on modulation of their rotational correlation time. The magnitude of such MRI signal changes is highly dependent on the magnetic field and the response decreases dramatically at high fields (>2 T).

Molecules, 2023 The hydration process of Portland cement is still not completely understood. For instance, it is not clear what produces the induction period, which follows the initial period of fast reaction, and is characterized by a reduced reactivity.

Measurement of fibrin concentration by fast field‐cycling NMR [PDF]
Magnetic Resonance in Medicine, 2011 AbstractThe relaxation of 1H nuclei due to their interaction with quadrupolar 14N nuclei in gel structures is measured using fast field‐cycling NMR. This phenomenon called quadrupolar dips has been reported in different 1H‐14N bond‐rich species. In this study, we have studied quadrupolar dips in fibrin, an insoluble protein that is the core matrix of ...
