Evaluation du dispositif d'urgences sociales EMUS [PDF]

open access: yes, 2014
Le concept EMUS (équipe mobile d'urgences sociales) trouve son origine dans la réunion consacrée à l'urgence sociale qui s'est tenue en fin d'année 2009 et dans le rapport sur la création de l'équipe mobile d'urgence établi en été 2010 à la suite de ...

Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation

open access: yesAdvanced Science, EarlyView.
Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical

Tuning Li+ and Na+ Functionality in Renewable Carbon Electroactive Material Through Site‐Specific Nanostructural Disorder

open access: yesAdvanced Science, EarlyView.
This study presents a selective thermal transformation of polycarbonate into hybrid carbon materials. The structured carbon enhances electrochemical performance, particularly in lithium‐ion systems. Investigations reveal improved bimetallic ion diffusivity through the hybrid microstructure, contributing to excellent charge kinetics.

Will EMU Increase Eurosclerosis? [PDF]

open access: yes, 2001
In this paper we study the relationship between labour market institutions and monetary policy. We use a simple macroeconomic framework to show how optimal monetary policy rules depend on labour institutions (labour adjustment costs, and nominal and real wage rigidity) and social preferences regarding inflation, employment, and real wages.

Gate Enhancing Charge‐Spin Conversion in Organic Chiral Field Effect Transistors

open access: yesAdvanced Science, EarlyView.
Room‐temperature organic chiral multiferroic field effect transistors are demonstrated, enabling bidirectional control between spin and charge. Specifically, spin polarization affects the ferroelectric polarization, and ferroelectric polarization, in turn, can modulate spin polarization and spin‐dependent transport.

Exchange Length Tailored Magnetic Resonance for Broadband Absorption in FeCo‐Based Alloys

open access: yesAdvanced Science, EarlyView.
To break the high‐frequency magnetic loss bottleneck in soft magnetic alloys, a magnetic exchange length (Lex)‐guided strategy is proposed. Cu doping increases Lex and intergranular coupling, which effectively reduces magnetic anisotropy and pushes the exchange resonance to 12.0 GHz.
