Proton polarization above 70% by DNP using photo-excited triplet states, a first step towards a broadband neutron spin filter

The use of polarized protons as neutron spin filter is an attractive alternative to the well established neutron polarization techniques, as the large, spin-clepenclent neutron scattering cross-section for protons is useful up to the sub-MeV region. Employ ...

Defect levels at GaAs/Al2O3 interfaces: As-As dimer vs. Ga dangling bond

Alfredo Pasquarello, Giacomo Francesco Leonardo Miceli

Charge transition levels of the As-As dimer and the Ga dangling bond at GaAs/Al2O3 interfaces are determined through density-functional calculations. The same parent interface model structure is used as a starting point for creating both defects providing ...

Evaluation of the natural vibration frequencies of a historical masonry building accounting for SSI

Angelo Garofano

The dynamic identification of a historical masonry palace located in Benevento (Italy) has been carried out. The case study is representative of many buildings located in historic Italian centres. Since the building has been instrumented by the Department ...

Drug Screening Boosted by Hyperpolarized Long-Lived States in NMR

Geoffrey Bodenhausen, Sandrine Gerber, Aurélien Bornet, Sami Jannin, Jonas Milani, 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. ...

Boundary layer effects on the vortex shedding in a Donaldson-type hydrofoil

François Avellan, Mohamed Farhat, Amirreza Zobeiri, Eduard Egusquiza

Structure Interaction (FSI) phenomena is becoming a relevant study field for the design or revamping of hydropower plants. The generalized trend of increasing flow rates and reducing rotor blades/stay vanes thickness in order to improve the efficiency of t ...

Procédé pour spectroscopie RMN d'échantillons solides

Geoffrey Bodenhausen, Simone Ulzega, Marc Anthony Caporini

A method for performing magnetic resonance spectroscopy on solid sample containing nuclei of interest with spin quantum number I, comprising: subjecting the sample to a static magnetic field, spinning the sample at the magic angle and broad-band excitation ...

Assessing the performance of computational methods for the prediction of the ground state structure of a cyclic decapeptide

Ursula Röthlisberger, Thomas Rizzo, Ivano Tavernelli, Natalia Nagornova, Matteo Guglielmi

We benchmark the performance of various computational approaches, ranging from the classical nonpolarizable force fields AMBER FF96 and FF99SB, the polarizable force fields AMBER FF02polEP and AMOEBAbio09 to the semiempirical DFT method SCC-DFTB. The test ...

Interband spin-orbit coupling between anti-parallel spin states in Pb quantum well states

Jan Hugo Dil, Stefan Peter Muff

Using spin and angle-resolved photoemission spectroscopy we investigate a momentum region in Pb quantum well states on Si(111) where hybridization between Rashba-split bands alters the band structure significantly. Starting from the Rashba regime where the ...

Iterative deconvolution of quadrupole split NMR spectra

Frédéric Mila

We propose a simple method to deconvolute NMR spectra of quadrupolar nuclei in order to separate the distribution of local magnetic hyperfine field from the quadrupole splitting. It is based on an iterative procedure which allows to express the intensity o ...

Muons probe magnetism and hydrogen interaction in graphene

Oleg Yazyev

Muon spin resonance (mu SR) is a powerful technique for investigating the local magnetic fields in materials through implanted muons. Here we report a mu SR study of chemically produced thermally exfoliated graphene. Our results provide an experimental ans ...
