TL;DR: Measurements of the Larmor frequency dependence of T1, are consistent with a spin‐lattice relaxation rate of the form 1/Tl = Aω−1/2+ B as expected for the case in which the relaxation arises from water‐biopolymer cross‐relaxation, which should be proportional to the surface area of the lung.
Journal ArticleDOI
On the use of pulse NMR techniques for the study of cement hydration
TL;DR: In this article, the application of pulse NMR to the study of hydration of cement and its constituents is discussed, where the quantity of adsorbed water in hydrated samples can be most easily determined by measuring the proton free induction decay signal, whereas the rates of hardening and hydration can be best followed by measuring proton spin-lattice and spin-spin relaxation times.
Journal ArticleDOI
NMR self-diffusion study of polyethylene and paraffin melts
TL;DR: The self-diffusion coefficient D of paraffin and polyethylene melts was measured by the pulsed-magnetic-field-gradient NMR method for diffusion times between 3 ms and 1 s as mentioned in this paper.
Journal ArticleDOI
The low temperature oxidation of Athabasca oil sand asphaltene observed from 13C, 19F, and pulsed field gradient spin-echo proton n.m.r. spectra
TL;DR: In this paper, the authors show that low temperature air oxidation of asphaltene, at ca. 130°C for 3 days, generates a few additional carboxyl and phenolic groups, consistent with a mechanism in which diaryl methylene and ether moieties react with oxygen.
