Towards microstructure fingerprinting: Estimation of tissue properties from a dictionary of Monte Carlo diffusion MRI simulations

Jean-Philippe Thiran, Gabriel Girard, Gaëtan Olivier D Rensonnet, Benoît Macq

Many closed-form analytical models have been proposed to relate the diffusion-weighted magnetic resonance imaging (DW-MRI) signal to microstructural features of white matter tissues. These models generally make assumptions about the tissue and the diffusio ...

Single step synthesis of Schottky-like hybrid graphene - titania interfaces for efficient photocatalysis

Aleksandra Radenovic

The development of 2D nanomaterial coatings across metal surfaces is a challenge due to the mismatch between the metal microstructure and the nanoscale materials. The naturally occurring thin oxidative layer present across all metal surfaces, may lead to l ...

Structural, tribo-mechanical, and thermal properties of NbAlN coatings with various Al contents deposited by DC reactive magnetron sputtering

Silviu Cosmin Sandu

DC reactive magnetron sputtered Nb2AlyNx coatings with various Al contents (y/(y + z)) ranging from 0 to 0.75 were deposited using different ratios of the currents applied to the Al and Nb targets in order to systematically control their chemical compositi ...

Erosion mechanisms during abrasive waterjet machining: Model microstructures and single particle experiments

Stefano Mischler, Johann Michler

The erosion mechanisms during abrasive waterjet (AWJ) machining have been examined for a variety of materials. However, no systematic study has considered the effect of the microstructure property relationship on the erosion mechanisms in metals. In this w ...
