Enabling Quantitative Benchtop 13C NMR Spectroscopy in Fast Continuous Flow
Magnetic Resonance in Chemistry, EarlyView.Paramagnetic relaxation enhancement (PRE) accelerates polarization buildup in continuous‐flow benchtop 13$$ {}^{13} $$C NMR spectroscopy by the use of an immobilized PRE agent. By combining PRE with PENDANT polarization transfer, weak 13$$ {}^{13} $$C signals are enhanced even at high flow rates, enabling robust quantitative analysis of solvent ...

A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.

Unveiling Saint Theobald: A Multidisciplinary Bioanthropological Investigation
International Journal of Osteoarchaeology, EarlyView.ABSTRACT Saint Theobald of Provins (1033–1066), a French nobleman who embraced voluntary poverty, hermitism, and pilgrimage, represents an early figure in the medieval ascetic movement. He holds historical significance for the diffusion of 11th‐century ascetic ideals, as a hermit saint associated with the Camaldolese order and venerated across northern

Quantification of hyperpolarisation efficiency in SABRE and SABRE-Relay enhanced NMR spectroscopy [PDF]
Physical Chemistry Chemical Physics, 2018 The linear relationship between the level of p-H2 enrichment and the polarisation of the target molecule provides a route to quantifying the efficiency of the signal amplification by reversible exchange (SABRE) and SABRE-Relay NMR hyperpolarisation methods.
