Magnetic Merry Go Round - Resonant Reshaping of Colloidal Clusters on a Current Carrying Wire
Lydiane Becu, Marc Basler, Miodrag L. Kulić +1
We describe a simple physical method for trapping and transforming magnetic colloid clusters on a current carrying wire. We use the wire's field as a mould to form colloidal rings…
Yielding and flow in adhesive and non-adhesive concentrated emulsions
L. Becu, S. Manneville, A. Colin
The nonlinear rheological response of soft glassy materials is addressed experimentally by focusing on concentrated emulsions where interdroplet attraction is tuned through varying…
Spatio-temporal dynamics of wormlike micelles under shear
L. Becu, S. Manneville, A. Colin
Velocity profiles in a wormlike micelle solution (CTAB in D2O) are recorded using ultrasound every 2 s after a step-like shear rate into the shear-banding regime. The stress relaxa…
High-frequency ultrasonic speckle velocimetry in sheared complex fluids
S. Manneville, L. Becu, A. Colin
High-frequency ultrasonic pulses at 36 MHz are used to measure velocity profiles in a complex fluid sheared in the Couette geometry. Our technique is based on time-domain cross-cor…
