Long-lived states to sustain hyperpolarized magnetization

Geoffrey Bodenhausen, Jean-Philippe Ansermet, Arnaud Comment, Sami Jannin, Riddhiman Sarkar, Paul Romeo Vasos, Puneet Ahuja

Major breakthroughs have recently been reported that can help overcome two inherent drawbacks of NMR: the lack of sensitivity and the limited memory of longitudinal magnetization. Dynamic nuclear polarization (DNP) couples nuclear spins to the large reserv ...

High-Precision MRI Reconstruction Algorithm for 3D Sphere Packings

Arnaud Comment, Daniele Mari, Riccardo Balzan, Alessandro Luigi Sellerio

Packings of granular materials are complex systems consisting of large sets of particles interacting via contact forces. Their internal structure is interesting for several theoretical and practical reasons, especially when the model system consists in a l ...

A link between short-range and long-range properties of random sphere packings

Arnaud Comment, Daniele Mari, Gérard Gremaud, Riccardo Balzan, Alessandro Luigi Sellerio

We present a high precision particle-by-particle 3D reconstruction of granular systems composed of monodispersed spheres (sphere packings); the experimental approach is based on magnetic resonance imaging techniques. Our measurements revealed a strong corr ...
