Les sociétés populaires à travers leurs procès-verbaux

Sous la Révolution française, les sociétés populaires ont créé et animé des réseaux de sociabilité politique dont leurs procès-verbaux sont des témoins. Ces délibérations sont des sources remarquables que la collection des "Documents inédits sur l’histoire de France", publiée sous l’égide du Comité des travaux historiques et scientifiques, permet de redécouvrir. Les études réunies dans cet ouvrage nous invitent à mieux comprendre le fonctionnement des sociétés populaires et à mesurer l’importance de leurs archives pour l’histoire politique et sociale

Saccadic Eye Movements and Attentional Control in Alzheimer's Disease

International audienceSeveral studies have demonstrated saccadic eye movement (SEM) abnormalities in Alzheimer's disease (AD) when patients performed prosaccade (PS) and antisaccade (AS) tasks. Some studies have also showed that SEM abnormalities were correlated with dementia rating tests such as the Mini Mental State Evaluation (MMSE). Therefore, it has been suggested that SEMs could provide useful information for diagnosis. However, little is known about predictive saccades (PreS)-saccades triggered before or very quickly after stimuli appearance-and their relationships with cognition in AD. Here, we aimed to examine the relationships between our usual dementia screening tests and SEM parameters in PS, AS, and also PreS task

Metal-Assisted Chemical Etching for the Direct Synthesis of Bimetallic Cu-Pd Nanoparticles on Silicon

An original study is presented for the synthesis of Cu100-xPdx nanoparticles directly on silicon by Metal Assisted Chemical Etching (MACE). CuPd is chosen as a representative bimetallic system on account of its interest and potential applications in catalysis and electrocatalysis, among others. The proposed methodology allows precise control of the nanoparticle bimetallic composition and structure. Thus, we demonstrate that Cu100-xPdx solid solutions and phase-separated nanoparticles can be synthesized at will by simply changing the deposition conditions. In-depth physical characterization of the synthesized material (structure, morphology, composition, oxidation state and d-band center position) is carried out by XRD, SEM-EDX and XPS. Finally, band bending simulations at the nanoscale in combination with electrochemical measurements help to interpret some of the peculiarities of the Pd, Cu and CuxPd100-x deposits. The new method can be easily implemented, used for various silicon substrate geometries and extended to any bimetallic system whose metals are suitable for MACE of silicon
