Monitoring cheese ripening by single-sided nuclear magnetic resonance

Journal of Dairy Science, 2023
: The noninvasive, longitudinal study of products and food processing is of interest for the dairy industry. Here, we demonstrated that single-sided nuclear magnetic resonance (NMR) can be used for noninvasive monitoring of the cheese ripening process ...

NMR relaxation and resistivity from rattling phonons in pyrochlore superconductors

, 2007
We calculate the temperature dependence of NMR relaxation rate and electrical resistivity for coupling to a local, strongly anharmonic phonon mode. We argue that the two-phonon Raman process is dominating NMR relaxation.

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

Advanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Beyond excitation NMR relaxation

Concepts in Magnetic Resonance Part A, 2008
AbstractThe understanding of NMR relaxation processes allows us to comprehend a variety of experiments ranging from the recording of spectra to the determination of images. A brief history of NMR spectroscopy, the state of the art of this technique, as well as its comparison with the coupling constants and chemical shifts measured in the condensed ...

Ultrahigh‐Yield, Multifunctional, and High‐Performance Organic Memory for Seamless In‐Sensor Computing Operation

Advanced Functional Materials, EarlyView.
Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Influencing factors of rock surface relaxivity and pore size conversion method for overpressured reservoirs in Huangliu Formation of Dongfang area, Yinggehai Basin

Shiyou shiyan dizhi
The overpressured reservoirs in the Huangliu Formation of the Dongfang area, Yinggehai Basin, are characterized by fine lithology, poor physical properties, complex storage space, and strong heterogeneity, which lead to poor correspondence between ...

Angle-resolved NMR: quantitative theory of 75As T1 relaxation rate in BaFe2As2

, 2011
While NMR measurements of nuclear energy spectra are routinely used to characterize the static properties of quantum magnets, the dynamical information locked in NMR 1/T1 relaxation rates remains notoriously difficult to interpret.

Molecular orientational dynamics of the endohedral fullerene Sc$_{3}$N@C$_{80}$ as probed by $^{13}$C and $^{45}$Sc NMR [PDF]

, 2006
We measure 13C and 45Sc NMR lineshapes and spin-lattice relaxation times (T1) to probe the orientational dynamics of the endohedral metallofullerene Sc3N@C80.
