Spin Noise Detection of Nuclear Hyperpolarization at 1.2K

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud

We report proton spin noise spectra of a hyperpolarized solid sample of commonly used DNP (dynamic nuclear polarization) juice containing TEMPOL (4-hydroxy-2,2,6,6-tetramethylpiperidine N-oxide) and irradiated by a microwave field at a temperature of 1.2K ...

Excitation of Sodium Atoms Attached to Helium Nanodroplets: The 3p

Marcel Drabbels, Evgeniy Loginov, Alberto Hernando de Castro

The dynamics of Na atoms on the surface of helium nanodroplets following excitation via the 3p

Scanning Tunneling Microscopy using Superconducting Tips to Probe Absolute Spin Polarization

Matthias Alexander Eltschka

The interplay of superconductivity and magnetism is investigated for systems with dimensions ranging from the mesoscopic to the atomic scale by scanning tunneling microscopy (STM) at millikelvin temperatures and by numerical calculations. Based on geometri ...

Hybrid polarizing solids for pure hyperpolarized liquids through dissolution dynamic nuclear polarization

David Lyndon Emsley, Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud, David Benjamin Roger Antoine Gajan

Hyperpolarization of substrates for magnetic resonance spectroscopy (MRS) and imaging (MRI) by dissolution dynamic nuclear polarization (D-DNP) usually involves saturating the ESR transitions of polarizing agents (PAs; e.g., persistent radicals embedded in ...

Drug Screening Boosted by Hyperpolarized Long-Lived States in NMR

Geoffrey Bodenhausen, Sandrine Gerber, Aurélien Bornet, Jonas Milani, Sami Jannin, Basile Vuichoud, Solène Marcelle Françoise Marie Passemard, Nicola Salvi, Daniele Mammoli, Roberto Buratto, Maninder Singh, Aurélien Laguerre

Transverse and longitudinal relaxation times (T11 and T1) have been widely exploited in NMR to probe the binding of ligands and putative drugs to target proteins. We have shown recently that long-lived states (LLS) can be more sensitive to ligand binding. ...

Dynamics of Excited Sodium Atoms Attached to Helium Nanodroplets

Marcel Drabbels, Evgeniy Loginov

The dynamics of laser-excited sodium atoms at the surface of helium nanodroplets has been investigated as a function of quantum state. For all cases excitation of the system leads to desorption of the sodium atom from the droplet surface. The mean kinetic ...

Hyperpolarization without persistent radicals for in vivo real-time metabolic imaging

Mor-Miri Mishkovsky, Christophe Roussel, Andrea Capozzi, Jean-Noël Hyacinthe, Tian Cheng, Arnaud Comment, Najat Salameh, Yuhei Takado, Tim Rolf Eichhorn

Hyperpolarized substrates prepared via dissolution dynamic nuclear polarization have been proposed as magnetic resonance imaging (MRI) agents for cancer or cardiac failure diagnosis and therapy monitoring through the detection of metabolic impairments in v ...
