NMR Relaxation in Dendrimers

, 2017
Abstract This review focuses on recent advances in the theory of local orientational mobility in dendrimers that reveals in the NMR relaxation. In particular, we summarize recent results of analytic theory, computer simulations, and NMR relaxation experiments.

NMR Relaxation Studies of Elastomers

, 2015
Abstract I reviewed the recent studies of rubbery materials, especially which deal with relaxation phenomena. The NMR relaxations for rubbers have been widely investigated before developing the high-resolution solid-state NMR technique in early 1980s.

Elucidating the 1H NMR Relaxation Mechanism in Polydisperse Polymers and Bitumen using Measurements, MD Simulations, and Models.

Journal of Physical Chemistry B, 2020
The mechanism behind the 1H NMR frequency dependence of T1 and the viscosity dependence of T2 for polydisperse polymers and bitumen remains elusive. We elucidate the matter through NMR relaxation measurements of polydisperse polymers over an extended ...

1D and 2D Nuclear magnetic resonance (NMR) relaxation behaviors of protons in clay, kerogen and oil-bearing shale rocks

, 2020
Few 1D T2 and 2D T1-T2 Nuclear magnetic resonance (NMR) studies have focused on oil-bearing shales with complex constituents and a deeper understanding of the NMR relaxation behaviors of oil confined in shale is needed.

Spectral Estimation of NMR Relaxation

Journal of Magnetic Resonance, 2000
In this paper, spectral estimation of NMR relaxation is constructed as an extension of Fourier Transform (FT) theory as it is practiced in NMR or MRI, where multidimensional FT theory is used. nD NMR strives to separate overlapping resonances, so the treatment given here deals primarily with monoexponential decay.

NMR relaxation studies with MnDPDP

Acta Radiologica, 1997
Purpose: Our studies were designed to compare the efficacy of mangafodipir triso-dium (MnDPDP, Teslascan) as a tissue-specific MR agent with that of manganese chloride (MnCl2), to compare the efficacy of different doses and rates of administration of MnDPDP, and to collect the data needed for predicting optimum pulse sequences.
