NMR in rapidly rotated metals by Tiffen, R. S.

“…One part deals with a series of measurements on the NMR parameters of several pure metal powders, namely aluminium, cadmium, niobium and vanadium, and in particular the effect on their resonance spectra of rapid macroscopic sample rotation at the 'magic angle'. …”

NMR hyperpolarization techniques of gases by Barskiy, Danila A., Coffey, Aaron M., Nikolaou, Panayiotis, Mikhaylov, Dmitry M., Goodson, Boyd M., Branca, Rosa T., Lu, George J., Shapiro, Mikhail G., Telkki, Ville-Veikko, Zhivonitko, Vladimir V., Koptyug, Igor V., Salnikov, Oleg G., Kovtunov, Kirill V., Bukhtiyarov, Valerii I., Rosen, Matthew S., Barlow, Michael J., Safavi, Shahideh, Hall, Ian P., Schröder, Leif, Chekmenev, Eduard Y.

“…Nuclear spin polarization can be significantly increased through the process of hyperpolarization, leading to an increase in the sensitivity of nuclear magnetic resonance (NMR) experiments by 4–8 orders of magnitude. Hyperpolarized gases, unlike liquids and solids, can often be readily separated and purified from the compounds used to mediate the hyperpolarization processes. …”

NMR studies of phase behaviour in polyacrylonitrile solutions by Golightly, John Anthony

“…The study of the PAN diffusion coefficient (D~10-7-10-6 cm²s-1) was limited by the experimental constraints of the NMR spectrometer. A 1H NMR one-dimensional imaging technique was used to study the nonsolvent induced phase separation (coagulation) of a PAN solution. …”

Capillary trapping quantification in sandstones using NMR relaxometry by Connolly, P., Vogt, S., Iglauer, Stefan, May, E., Johns, M.

“…Here we demonstrate the successful use of low field 1 H Nuclear Magnetic Resonance [NMR] to quantify capillary trapping; specifically we use transverse relaxation time [T 2 ] time measurements to measure both residual water [wetting phase] content and the surface-to-volume ratio distribution (which is proportional to pore size] of the void space occupied by this residual water. …”
