Quantum and thermal ionic motion, oxygen isotope effect, and superexchange distribution in La2CuO4

Sandrine Gerber, Bastien Dalla Piazza, Bruce Normand, Henrik Moodysson Rønnow, Kazimierz Conder, Vera Irina Schnells

We study the zero-point and thermal ionic motion in La2CuO4 by means of high-resolution neutron-diffraction experiments. Our results demonstrate anisotropic motion of O and, to a lesser extent, Cu ions, both consistent with the structure of coupled CuO6 oc ...

Drug Screening Boosted by Hyperpolarized Long-Lived States in NMR

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

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. ...
