Mechanics and structure of carbon black gels under high-power ultrasound
Noémie Dagès, Pierre Lidon, Guillaume Jung +3
Colloidal gels made of carbon black particles dispersed in light mineral oil are "rheo-acoustic" materials, i.e., their mechanical and structural properties can be tuned using high…

Colloidal transport in bacteria suspensions: from bacteria scattering to anomalous and enhanced diffusion
Antoine Lagarde, Noémie Dagès, Takahiro Nemoto +3
Colloids coupled to a bath of swimming cells generically display enhanced diffusion. This transport dynamics stems from a subtle interplay between the active and passive particles…

Rheo-acoustic gels: Tuning mechanical and flow properties of colloidal gels with ultrasonic vibrations
Thomas Gibaud, Noémie Dagès, Pierre Lidon +7
Colloidal gels, where nanoscale particles aggregate into an elastic yet fragile network, are at the heart of materials that combine specific optical, electrical and mechanical prop…
