New applications and perspectives of fast field cycling NMR relaxometry
Magnetic Resonance in Chemistry, 2015The field cycling NMR relaxometry method (also known as fast field cycling (FFC) when instruments employing fast electrical switching of the magnetic field are used) allows determination of the spin‐lattice relaxation time (T1) continuously over five decades of Larmor frequency.

Fast field-cycling nuclear magnetic resonance spectrometer
Review of Scientific Instruments, 1996We describe here the design and construction of a modern, state-of-the-art nuclear magnetic resonance (NMR) field-cycling instrument. Fourier transform NMR spectra of both liquid and solid samples can be measured, and spin-lattice relaxation times (T1Z) investigated over a broad range of magnetic field strengths ranging from 0 to 2 T. The instrument is

NMR Fast Field Cycling Relaxometry of Unsaturated Soils
Applied Magnetic Resonance, 2014The bioavailability of water for plant nutrition in natural soils is controlled by the pore system structure and the interaction of water with the pore walls at variable degrees of saturation. For the characterization of these processes T 1 relaxometry is particularly suitable because it is not influenced by internal gradients and the ...

Applications of fast field cycling NMR relaxometry
2021Fast field cycling (FFC) NMR relaxometry is emerging as a powerful tool to investigate physical chemistry properties of many systems in a number of different scientific fields. As an example, it is used to investigate environmental issues such as soil erosion, water, and nutrient dynamics in environmentally relevant porous systems, to discriminate ...

Wettability Evaluation by Fast Field Cycling NMR Relaxometry
SPE Kingdom of Saudi Arabia Annual Technical Symposium and Exhibition, 2018Abstract Wettability is an essential concept to understand oil trapping due to adhesion and capillary forces, and it depends on the fluid/rock molecular interactions within the thin liquid layer on the pore surface. The conventional methods for wettability determination exploit its macroscopic averaging effects during various ...

Inverse Methods for Fast Field Cycling and NMR Correlation Experiments
2023This thesis focuses on the development of inverse methods for nuclear magnetic res- onance (NMR) correlation or exchange experiments and new fast field cycling (FFC) modelling approaches. Moreover, the theoretical framework to consider fast field cycling as an inverse problem is provided and the possibility to employ established regularization methods ...

Rapid field-cycling MRI using fast spin-echo
Magnetic Resonance in Medicine, 2015Fast field-cycling MRI (FFC-MRI) is a technique that promises to expand upon the diagnostic capabilities of conventional MRI by allowing the main field, B0 , to be varied during a pulse sequence, thus allowing access to new types of endogenous contrast.
