Cross Polarization for Dissolution Dynamic Nuclear Polarization Experiments at Readily Accessible Temperatures 1.2 < T < 4.2 K

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin

Cross polarization can provide significant enhancements with respect to direct polarization of low-gamma nuclei such as C-13. Substantial gains in sample throughput (shorter polarization times) can be achieved by exploiting shorter build-up times tau(DNP)( ...

Low-temperature cross polarization in view of enhancing dissolution Dynamic Nuclear Polarization in NMR

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin

Dynamic Nuclear Polarization (DNP) induced by saturation of ESR transitions of TEMPO at 1.2 K and 3.35 T is characterized by build-up rates that are typically 5 times faster for protons than for the carboxylic carbon-13 in acetate. We show that cross polar ...

Some methods of dynamic nuclear polarization for use in metabolic imaging

Fiodar Kurdzesau

It has been suggested already more than 60 years ago to use polarized nuclei in particle scattering experiments1, but only with the discovery of the solid effect dynamic nuclear polarization process2 the realisation of polarized solid targets became possib ...

Instrument-independent specification of the diffraction geometry and polarization state of the incident X-ray beam

This work augments the proposal of Schwarzenbach & Flack [J. Appl. Cryst. (1989), 22, 601-605], who have advocated the use of a diffractometer-independent definition of the azimuthal angle

\psi

to specify the diffractiongeometry of a Bragg reflection. It ...

Search for nuclear magnetic resonance evidence of spin accumulation

Aurore Rudolf

Developments towards an understanding of the nature of conductance at the interface between two different metallic layers – ferromagnetic and non magnetic – as well as the discovery of giant magnetoresistance have stirred attention from both the scientific ...

The theory of nuclear orientation via electron spin locking (NOVEL)

Nuclear orientation via electron spin locking (NOVEL) is a technique to orient nuclear spins embedded in a solid. Like other methods of dynamic nuclear polarization (DNP) it employs a small amount of unpaired electron spins and uses a microwave field to tr ...

Dynamic nuclear polarization of small labelled molecules in frozen water-alcohol solutions

Arnaud Comment, Sami Jannin, Jacques Van Der Klink, Fiodar Kurdzesau

In recent years methods of creating 'hyperpolarized' substances have gained considerable attention in biomedical magnetic resonance and dynamic nuclear polarization (DNP) is one of the most promising, especially for imaging applications. Here we present re ...

Design and performance of a DNP prepolarizer coupled to a rodent MRI scanner

Rolf Gruetter, Arnaud Comment, Sami Jannin, Jacques Van Der Klink, Fiodar Kurdzesau

For most of the last forty years, the techniques of Dynamic Nuclear Polarization (DNP) have been confined to particle-physics laboratories building polarized targets, but recently it has been shown that samples similar to a solid target can be transformed ...

Numerical aberrations compensation and polarization imaging in digital holographic microscopy

Tristan Colomb

In this thesis, we describe a method for the numerical reconstruction of the complete wavefront properties from a single digital hologram: the amplitude, the phase and the polarization state. For this purpose, we present the principle of digital holographi ...

Jones vector imaging by use of digital holography: simulation and experimentation

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet

We present a method to image Jones vector by use of digital holography. We demonstrate that with a single hologram acquisition, the method allows to image and to calculate Jones vector and derive the polarization parameters. The principle consists in using ...
