Viscoelastic surface electrode arrays to interface with viscoelastic tissues

Nicolas Vachicouras, Florian Dylan Fallegger, Stéphanie Lacour, Christina Myra Tringides, Alix Esther Anne Trouillet

Bioelectronic interfacing with living tissues should match the biomechanical properties of biological materials to reduce damage to the tissues. Here, the authors present a fully viscoelastic microelectrode array composed of an alginate matrix and carbon-b ...

Silk granular hydrogels self-reinforced with regenerated silk fibroin fibers

Dominique Pioletti, Pierre-Etienne Bourban, Céline Samira Wyss, Peyman Karami, Adrien Julien Demongeot

Granular hydrogels with high stability, strength, and toughness are laborious to develop. Post-curing is often employed to bind microgels chemically and enhance mechanical properties. Here a unique strategy was investigated to maintain microgels together w ...

Computational micromechanics of porous brittle solids

Henning Löwe, Johan Alexandre Philippe Gaume, Lars Kristoffer Uhlen Blatny, Stephanie Wang

Porous brittle solids evidence complex mechanical behavior, where localized failure patterns originate from mechanical processes on the microstructural level. In order to investigate the failure mechanics of porous brittle solids, we outline a general stoc ...

Tensile response of Ultra High Performance PE Fiber Reinforced Concretes (PE-UHPFRC) under imposed shrinkage deformations

Emmanuel Denarié, Mohamed Abdul Hafiz, Amir Hajiesmaeili

PE-UHPFRC is a new Ultra High-Performance Fiber Reinforced Concrete (UHPFRC), which is developed to reduce the environmental impact of conventional UHPFRC by replacing the steel fibers with synthetic ones and reducing the clinker content in the mix. The de ...

Effect of the mineralogical composition on the elastoplastic hydromechanical response of Opalinus Clay shale

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

Opalinus Clay is the shale currently under investigation as the host formation for geological radioactive waste disposal in Switzerland. Its hydromechanical response has been widely studied, and the experimental results show a range of values whose dispers ...

Surface modified microfibrillated cellulose‐poly(vinylidene fluoride) composites: β‐phase formation, viscoelastic and dielectric performance

Dragan Damjanovic, Yves Leterrier, Véronique Michaud, Mohammed Arif Poothanari

The effect of silylation of microfibrillated cellulose (MFC) surfaces on β‐phase formation in poly(vinylidene difluoride) (PVDF) and the resulting viscoelastic and dielectric performance of MFC‐PVDF composites is investigated. Two different organosilanes, ...

Experimental plastic reactivation of pseudotachylyte‐filled shear zones

Marie Estelle Solange Violay, François Xavier Thibault Passelègue

Pseudotachylytes are fine‐grained fault rocks that solidify from melt that is produced in fault zones during earthquakes. Exposed sections of natural fault zones reveal evidence of post‐seismic plastic deformation (i.e. reactivation) of pseudotachylyte, wh ...
