Constitutive analysis of the mechanical anisotropy of Opalinus Clay

Lyesse Laloui, Bertrand François, Mathieu Nuth, Simon Salager

This paper aims to analyse the anisotropic features of behaviour of Opalinus Clay using the theory of plastic multi-mechanisms. The results of triaxial tests conducted with different load levels and directions showed that the mechanical behaviour of this s ...

Magnetism of Single Adatoms and Small Adsorbed Clusters Investigated by Means of Low-Temperature STM

Quentin Dubout

This thesis works reports on the magnetic properties of single transition metal atoms and hydrogenated compounds adsorbed on crystal surfaces. It is an experimental study, based on scanning tunneling microscopy (STM), initiated by the project of demonstrat ...

Observation Of Cosmic-Ray Anisotropy With The Icetop Air Shower Array

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We report on the observation of anisotropy in the arrival direction distribution of cosmic rays at PeV energies. The analysis is based on data taken between 2009 and 2012 with the IceTop air shower array at the south pole. IceTop, an integral part of the I ...

First-principles model for phase stability, radiation defects and elastic properties Of W–Ta and W–V alloys

Nadine Baluc

Tungsten alloys are candidate materials for DEMO divertor applications because of their high melting point and low sputtering yield. We explore, using ab initio methods, the phase stability trend of W-Ta and W-V alloys. The available experimental phase dia ...

Optofluidic-tunable color filters and spectroscopy based on liquid-crystal microflows

Demetri Psaltis, Andreas Vasdekis, Julien Cuennet

The integration of color filters with microfluidics has attracted substantial attention in recent years, for on-chip absorption, fluorescence, or Raman analysis. We describe such tunable filters based on the micro-flow of liquid crystals. The filter operat ...

Strain-dependent magnetic configurations in manganite-titanate heterostructures probed with soft X-ray techniques

Harald Brune, Stefano Rusponi

We present a detailed study on the strain-induced magnetic domain structure of a (La,Sr)MnO3 thin film epitaxially grown on a BaTiO3 substrate through the use of polarization-dependent X-ray photoemission electron microscopy and X-ray absorption spectrosco ...

Magnetic states in low-pinning high-anisotropy material nanostructures suitable for dynamic imaging

André Bisig

We present magnetic domain states in a material configuration with high (perpendicular) magnetic anisotropy and particularly low magnetic pinning. This material, a B-doped Co/Pt multilayer configuration, exhibits a strong magnetic contrast in x-ray transmi ...

Magnonic band structures in two-dimensional bi-component magnonic crystals with in-plane magnetization

Dirk Grundler

We investigate the magnonic band structure of in-plane magnetized two-dimensional magnonic crystals composed of cobalt dots embedded into a permalloy antidot lattice. Our analysis is based on the results of numerical calculations carried out by the plane w ...

Investigation of field and diffusion time dependence of the diffusion-weighted signal at ultrahigh magnetic fields

Rolf Gruetter, Yohan Van de Looij, Nicolas Kunz

Over the last decade, there has been a significant increase in the number of high-magnetic-field MRI magnets. However, the exact effect of a high magnetic field strength (B0 ) on diffusion-weighted MR signals is not yet fully understood. The goal of this s ...
