Tribocorrosion behavior of beta titanium alloys in physiological solutions containing synovial components

In this work, the tribocorrosion behavior of Ti-12.5Mo, Ti-13Nb-13Zr and Ti-29Nb-13Ta-4.6Zr beta titanium alloys which are candidate biomaterials for joint prostheses is studied against ultra high molecular weight polyethylene in Hank's balanced salt solut ...

Fretting-corrosion behavior of beta titanium alloys in simulated synovial fluid

Stefano Mischler

Fretting-corrosion is a material degradation process resulting from the combined action of a corrosive environment and small displacement fretting wear. In this work, the fretting-corrosion behavior of Ti-12.5Mo, Ti-13Nb-13Zr, and Ti-29Nb-13Ta-4.6Zr, beta ...

Estimating hybrid choice models with the new version of Biogeme

Michel Bierlaire

Hybrid choice models integrate many types of discrete choice modeling methods, including latent classes and latent variables, in order to capture concepts such as perceptions, attitudes, preferences, and motivatio (Ben-Akiva et al., 2002). Although they pr ...

Kinetics of Yttrium-Ligand Complexation Monitored Using Hyperpolarized 89Y as a Model for Gadolinium in Contrast Agents

Geoffrey Bodenhausen, Lothar Helm, Pascal Miéville, Sami Jannin

Hyperpolarization by dissolution dynamic nuclear polarization (DNP) enhances Y-89 spin magnetization by 3 to 4 orders of magnitude and provides a way to monitor yttrium-ligand complexation "on the fly" by means of Y-89 NMR. In this communication, we show a ...

On the lattice coherency of oxide particles dispersed in EUROFER97

Nadine Baluc, Robin Schäublin, Amuthan Ramar

Oxide dispersion strengthened steels based on the ferritic/martensitic steel EUROFER97 are developed. The reinforcing particles dispersed in the matrix of EUROFER97 are made of yttria and yttrium titanium oxides. Microstructure is investigated by transmiss ...

In situ reduction and oxidation of nickel from solid oxide fuel cells in a Titan ETEM

Jan Van Herle, Quentin Thomas Jeangros, Antonin Faes

Environmental transmission electron microscopy was used to characterize in situ the reduction and oxidation of nickel from a Ni/YSZ solid oxide fuel cell anode support between 300-500°C. The reduction is done under low hydrogen pressure. The reduction init ...

In situ X-ray tomography observation of inhomogeneous deformation in semi-solid aluminium alloys

Michel Rappaz, Milan Felberbaum

The aim of this paper is to report the very first in situ observations of the deformation behaviour of an Al-Cu alloy in the semisolid state by using ultrafast, high-resolution X-ray microtomography. It is shown that this deformation is non-homogeneous and ...

Ageing of anode-supported solid oxide fuel cell stacks including thermal cycling, and expansion behaviour of MgO-NiO anodes

Jan Van Herle, Stefan Diethelm

This paper reports on medium term tests of anode-supported five-cell short stacks, as well as on some separate anode development. Two stacks were operated under steady-state conditions: one with unprotected metal interconnects, H-2 fuel and 0.35 A cm(-2) ( ...

alpha-gamma transition in metallic Ce studied by resonant x-ray spectroscopies

Marco Grioni

We performed bulk-sensitive x-ray absorption (XAS) in the partial fluorescence yield (PFY) mode, and resonant x-ray emission (RXES) measurements of the solid solution Sc (7 at.%):Ce at the Ce L-3 (2p-->5d) and M-4,M-5 (3d-->4f) absorption edges. We deduce ...
