Spin Diffusion in Dynamic Nuclear Polarization Nuclear Magnetic Resonance
Dynamic Nuclear Polarization (DNP) is currently one of the most efficient ways of enhancing sensitivity in solid-state Nuclear Magnetic Resonance (NMR) experiments. The DNP protocol consists in doping a sample with a small amount of paramagnetic species, t ...
EPFL2018Surface-Enhanced NMR Spectroscopy
Dynamic Nuclear Polarization (DNP) is currently one of the most efficient ways of enhancing sensitivity in solid-state NMR experiments. The DNP protocol consists in doping a sample with a small amount of para-magnetic species, typically nitroxide biradical ...
EPFL2018Direct enhancement of nitrogen-15 targets at high-field by fast ADAPT-SABRE
Signal Amplification by Reversible Exchange (SABRE) is an attractive nuclear spin hyperpolarization technique capable of huge sensitivity enhancement in nuclear magnetic resonance (NMR) detection. The resonance condition of SABRE hyperpolarization depends ...
2017Progress towards in vivo brain (13)C-MRS in mice: Metabolic flux analysis in small tissue volumes
Rolf Gruetter, Bernard Lanz, Marta Lai
The combination of dynamic (13)C MRS data under infusion of (13)C-labeled substrates and compartmental models of cerebral metabolism enabled in vivo measurement of metabolic fluxes with a quantitative and distinct determination of cellular-specific activit ...
Elsevier2017Bound States and Field-Polarized Haldane Modes in a Quantum Spin Ladder
Bruce Normand, Christian Rüegg, Pierre Bouillot, Daniel Biner
The challenge of one-dimensional systems is to understand their physics beyond the level of known elementary excitations. By high-resolution neutron spectroscopy in a quantum spin-ladder material, we probe the leading multiparticle excitation by characteri ...
Amer Physical Soc2017Angular-dependent magnetization dynamics of kagome artificial spin ice incorporating topological defects
Dirk Grundler, Vinayak Shantaram Bhat
We report angular-dependent spin-wave spectroscopy on kagome artificial spin ice made of large arrays of interconnected Ni80Fe20 nanobars. Spectra taken in saturated and disordered states exhibit a series of resonances with characteristic in-plane angular ...
Amer Physical Soc2017Charge transport in superionic and melted AgI under a magnetic field studied via molecular dynamics
Charge transport in AgI subject to an external magnetic field is studied via computer simulations. We demonstrate that a recently developed algorithm can effectively complement problematic experiments to detect the ionic Hall effect, and identify previousl ...
Amer Physical Soc2016Compact Microwave Cavity with Increased Magnetic Field Homogeneity
Anja Skrivervik, Anton Evgeniev Ivanov
In this study we aim at improving the homogeneity of the magnetic field inside a microwave resonator cavity designed in line with the development of a novel, high performance frequency standard. We study the effect of modified boundary conditions applied t ...
2016Optimizing dissolution dynamic nuclear polarization
This article is a short review of some of our recent developments in dissolution dynamic nuclear polarization (d-DNP). We present the basic principles of d-DNP, and motivate our choice to step away from conventional approaches. We then introduce a modified ...
Academic Press Inc Elsevier Science2016Improved surface coil design and pulse sequence development for in vivo 13C MR spectroscopy of humans at 7T
Nuclear magnetic resonance (NMR) is a non-invasive tool for the study of human diseases. In particular, carbon-13 magnetic resonance spectroscopy (13C MRS) is a promising derivative tool for investigating metabolism in vivo, as it allows the non-invasive m ...
