Du temps de travail au temps des marchés

open access: yesTemporalités, 2009
Following in Le Goff’s footsteps, inspired by the Middle Ages, we use the metaphor of the eruption of merchants’ time in a world dominated by agricultural activities. We retain two qualities of this sort of time. The first relates to the fundamental role

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Le travail, marchandise fictive ? 100 ans de marchandisation de la main d’œuvre mexicaine aux États-Unis

open access: yesRevue Interventions Économiques, 2008
For Karl Polanyi, market society is impossible, since it supposes that work, land and money be treated as merchandise, which can only destroy society. On the basis of the analysis of the utilisation of Mexican labor by US firms over 100 years, this paper
