A spinning thermometer to monitor microwave heating and glass transitions in dynamic nuclear polarization

Geoffrey Bodenhausen, Sandrine Gerber, Sami Jannin, Pascal Miéville, Marc Anthony Caporini

As previously demonstrated by Thurber and Tycko, the peak position of Br-79 in potassium bromide (KBr) allows one to determine the temperature of a spinning sample. We propose to adapt the original design by using a compact KBr tablet placed at the bottom ...

Method for nmr spectrometry or mri measurement using dissolution dynamic nuclear polarization (dnp) with scavenging of free radicals

Geoffrey Bodenhausen, Sami Jannin, Pascal Miéville

PROBLEM TO BE SOLVED: To provide a method for extending longitudinal relaxation time and transverse relaxation time in nuclear magnetic resonance (NMR), while removing free radicals from hyperpolarized solution. SOLUTION: A method for preparing samples for ...

Hyperpolarizing Gases via Dynamic Nuclear Polarization and Sublimation

Arnaud Comment, Jean-Philippe Ansermet, Geoffrey Bodenhausen, François Lazeyras, Rolf Gruetter, Sami Jannin, Riddhiman Sarkar, Paul Romeo Vasos, Puneet Ahuja, Pascal Miéville, Jean-Noël Hyacinthe

A high throughput method was designed to produce hyperpolarized gases by combining lowtemperature dynamic nuclear polarization with a sublimation procedure. It is illustrated by applications to 129Xe nuclear magnetic resonance in xenon gas, leading to a si ...

Kinetics of Yttrium-Ligand Complexation Monitored Using Hyperpolarized 89Y as a Model for Gadolinium in Contrast Agents

Geoffrey Bodenhausen, Lothar Helm, Sami Jannin, Pascal Miéville

Hyperpolarization by dissolution dynamic nuclear polarization (DNP) enhances Y-89 spin magnetization by 3 to 4 orders of magnitude and provides a way to monitor yttrium-ligand complexation "on the fly" by means of Y-89 NMR. In this communication, we show a ...

Scavenging Free Radicals To Preserve Enhancement and Extend Relaxation Times in NMR using Dynamic Nuclear Polarization

Arnaud Comment, Geoffrey Bodenhausen, Sandrine Gerber, Rolf Gruetter, Sami Jannin, Riddhiman Sarkar, Paul Romeo Vasos, Puneet Ahuja, Pascal Miéville, Mor-Miri Mishkovsky

Vitamin C for longer lifetimes: N-oxide radicals that are widely used for dynamic nuclear polarization can be reduced by scavengers such as sodium ascorbate (vitamin C) during the dissolution process, thus diminishing losses of polarization during the tran ...
