Experimental and ab initio derivation of interface stress in nanomultilayered coatings: Application to immiscible Cu/W system with variable in-plane stress
Pandula Manura Liyanage, Claudia Cancellieri, Giacomo Lorenzin
Interface stress is a fundamental descriptor for interphase boundaries and is defined in strict relation to the interface energy. In nanomultilayers with their intrinsically high interface density, the functional properties are dictated by the interface st ...
Elsevier2024Bounding the localized to ductile transition in porous rocks: implications for geo-reservoirs
Marie Estelle Solange Violay, Gabriel Gérard Dominique Meyer
Porous rocks have long been the focus of intense research driven by their importance in our society as host to our most essential resources (oil, gas, water, geothermal energy, etc), yet their rheology remains poorly understood. With increasing depth, poro ...
2023Strain Gradients and Magnetoresistance in Microstructured 3D Topological Semi-metals
Three-dimensional topological semimetals have emerged as strong candidates to probe new fundamental physical phenomena that could be exploited to develop next generation electronics. However, many aspects of their electronic properties remain unclear. Thi ...
EPFL2023Engineering extracellular electron transfer for enhanced energy harvesting in microbial electrochemical devices
Microorganisms known as exoelectrogens evolved the ability of transporting electrons across insulating biological membranes. In a physiological context, this enables respiration on extracellular electron acceptors and electron transfer to other organisms. ...
EPFL2023Hydro-Mechanical Characterization of a Shale by Unusually High-Pressure Oedometric Tests
Alessio Ferrari, Eleonora Crisci
The note presents selected results of an experimental campaign conducted with the aim to investigate the hydro-mechanical behaviour of a shale recovered at a depth of about 900 m below the ground. High-pressure oedometric tests were performed to investigat ...
Wei Wu, Universität für Bodenkultur2023Bio-inspired Structures for Enhancing Energy Dissipation of Helmets
The risk of concussion remains high in snow sports, even with a high helmet adoption rate. Novel helmet designs with enhanced energy dissipation are needed to solve this issue. In this study, helmet liners with bio-inspired honeycomb structures were propos ...
2022Experimental quantification of 3D deformations in sensitive clay during stress-probing
Unique four-dimensional (4D) deformation data are collected during drained triaxial tests on intact specimens of a natural sensitive clay. This requires the development of a miniature triaxial cell for advanced stress path testing, specifically designed fo ...
ICE PUBLISHING2022Multi-scale experimental testing on variable stiffness and damping components for semi-active structural control
This paper presents experimental testing of a new semi-active vibration control device comprising a shape memory polymer (SMP) core that is reinforced by an SMP-aramid composite skin. This control device works as a load-transfer component that can be integ ...
ELSEVIER SCI LTD2022Theory of spontaneous grain boundary roughening in high entropy alloys
William Curtin, Carolina Baruffi
High Entropy Alloys (HEAs) are a new broad class of near-random solid solution alloys that can possess some impressive mechanical and physical properties including high stability against grain growth (i.e. low grain boundary (GB) mobility). Here, it is sho ...
PERGAMON-ELSEVIER SCIENCE LTD2022Quasi-static crack front deformations in cohesive materials
Jean-François Molinari, Thibault Didier Roch, Mathias Alexandre David Lebihain
When a crack interacts with material heterogeneities, its front distorts and adopts complex tortuous configurations that are reminiscent of the energy barriers encountered during crack propagation. As such, the study of crack front deformations is key to r ...
