Journal ArticleDOI
Porous elastomeric beads from crosslinked emulsions
TL;DR: In this article, a mechanically stirred thermostated water vessel is used to obtain high porosity polydimethylsiloxane (PDMS) beads with an open structure whose properties are strongly influenced by the starting composition (solvent, surfactant, and polymer types and ratios), as well as the operating parameters (agitation and temperature).
Journal ArticleDOI
Self ignition of layers of metal powder mixtures
Olivier Dufaud,David Bideau,Fabienne Le Guyadec,Jean-Pierre Corriou,Laurent Perrin,Audrey Caleyron +5 more
TL;DR: In this paper, a two-dimensional axisymmetric model was applied to the ignition characteristics of zirconium (Zr), tantalum (Ta) and Zr/Ta deposits on a hot surface.
Journal ArticleDOI
Proposal of a new injection nozzle to improve the experimental reproducibility of dust explosion tests
Carlos Murillo,Mariangel Amín,Nathalie Bardin-Monnier,Felipe Muñoz,Andrés Pinilla,Nicolás Ratkovich,David Torrado,Daniel Vizcaya,Olivier Dufaud +8 more
TL;DR: In this paper, the influence of the injection nozzle on the dispersion process of combustible dust in the 20 L sphere is established by developing a descriptive analysis by comparing the evolution of a dust cloud formed thanks to the standard rebound nozzle with that formed from a new symmetric nozzle.
Journal ArticleDOI
Reuse of medical face masks in domestic and community settings without sacrificing safety: Ecological and economical lessons from the Covid-19 pandemic.

Martin,Christophe Huet,Sandrine Boisset,Max Maurin,Pascal Rumeau,Frédéric Charlot,Emmanuel Richaud,Alexandre Moreau-Gaudry,Vincent Bonneterre,Philippe Cinquin,Caroline Landelle +34 more
TL;DR: In this article, the authors report a workflow that provides a quantitative basis to determine the safety and efficacy of a medical mask that is decontaminated for reuse, with the goal of finding ways to reuse medical and respiratory masks in healthcare departments.
Journal ArticleDOI
Explosions of methane/air/nanoparticles mixtures: Comparison between carbon black and inert particles
David Torrado,Valentina Buitrago,Pierre-Alexandre Glaude,Pierre-Alexandre Glaude,Olivier Dufaud,Olivier Dufaud +5 more
TL;DR: In this paper, the influence of carbon black nanopowders insertion on the explosion severity and on the flame velocity of methane was investigated in a 20-L explosion sphere and in a 1-m vertical flame propagation tube.
