Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Un casque apulo-corinthien du musée des Antiquités de Rouen

open access: yesLes Nouvelles de l’Archéologie, 2020
The conservation-restoration treatment carried out at the C2RMF on an "apulian-corinthian" type helmet kept at the Museum of Antiquities in Rouen provided the opportunity to carry out an in-depth study of this little-documented object.

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Blood Biomarkers and Surface‐Enhanced Raman Spectroscopy for Gout: A Comprehensive Review

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustrating gout disease progression from asymptomatic hyperuricemia to chronic tophaceous disease, highlighting the limitations of conventional imaging and biochemical diagnostics and the potential of engineered SERS platforms for ultrasensitive blood‐based detection of urate‐related biomarkers across disease stages, with the color gradient

Une statue d’Epona en tôle de bronze sur modèle en bois à Saint-Valérien (Yonne)

open access: yesRevue Archéologique de l’Est, 2013
Partial exploration (1,7 hectares) of a large village close to Sens has revealed enclosures and wooden constructions, some containing forges, close to a large galleried courtyard. The stages of development during the 1st and 2nd centuries were discerned,
