Reversible low-light induced photoswitching of crowned spiropyran-DO3A complexed with gadolinium(III) ions. [PDF]

open access: yes, 2012
Photoswitchable spiropyran has been conjugated to the crowned ring system DO3A, which improves its solubility in dipolar and polar media and stabilizes the merocyanine isomer. Adding the lanthanide ion gadolinium(III) to the macrocyclic ring system leads

Mn2+ Bispidine Complexes as Potential Magnetic Resonance Imaging Agents : Noncoordinating Peripheral Functional Groups Affect Structural, Kinetic, and Relaxation Properties

open access: yesChemistryEurope, Volume 4, Issue 1, January 2026.
In the family of Mn2+ complexes formed with pentadentate bispidine chelates, functional groups that do not interfere with metal coordination can play a significant role in enhancing kinetic inertness and proton relaxation efficacy. Mn2+ bispidine complexes combine unprecedented kinetic inertness with high relaxivity and are under scrutiny as potential ...

Water Molecular Dynamics During Dough Heating by Fast Field Cycling Nuclear Magnetic Resonance

open access: yesMagnetic Resonance in Chemistry, Volume 63, Issue 11, Page 954-963, November 2025.
Real time FFC measurements confirms the competition of water between gluten and starch granule, gluten hindering the starch water uptake and limits starch swelling in dough. ABSTRACT Measurements of the water 1H nuclear magnetic resonance (NMR) relaxation rate R1 in hydrated starch (SW), gluten (GW) and dough (DW) were performed at different ...

Dynamic water profile in various types of cheese analyzed by means of nuclear magnetic resonance relaxometry

open access: yesJournal of Dairy Science
: The aim of the study was to enquire to which extend 1H spin-lattice nuclear magnetic resonance (NMR) relaxometry data collected over a broad range of resonance frequencies (from 10 kHz to 10 MHz) have the potential to be used for assessing quality and ...

Metal-substituted protein MRI contrast agents engineered for enhanced relaxivity and ligand sensitivity [PDF]

open access: yes, 2010
Engineered metalloproteins constitute a flexible new class of analyte-sensitive molecular imaging agents detectable by magnetic resonance imaging (MRI), but their contrast effects are generally weaker than synthetic agents.

Probing Pedogenetic Imprints and Functional Properties of Moroccan Clayey Materials Through FFC NMR Relaxometry

open access: yesMagnetic Resonance in Chemistry, Volume 63, Issue 10, Page 796-809, October 2025.
Fast Field Cycling NMR relaxometry reveals how pedogenetic pathways imprint distinct dynamic signatures in Moroccan clays, shaping their microstructural heterogeneity and technological properties. ABSTRACT Understanding how soil formation processes influence the microstructure and the dynamic behavior of clay‐rich materials is essential for both ...

Uniform Penalty inversion of two-dimensional NMR Relaxation data

open access: yes, 2016
The inversion of two-dimensional NMR data is an ill-posed problem related to the numerical computation of the inverse Laplace transform. In this paper we present the 2DUPEN algorithm that extends the Uniform Penalty (UPEN) algorithm [Borgia, Brown ...
