Medium amplitude parallel superposition (MAPS) rheology. Part 2: Experimental protocols and data analysis

Journal article Journal of Rheology · September 1, 2020 Featured Work An experimental protocol is developed to directly measure the new material functions revealed by medium amplitude parallel superposition (MAPS) rheology. This protocol measures the medium amplitude response of a material to a simple shear deformation compo ... Full text Cite

Time-Resolved Mechanical Spectroscopy of Soft Materials via Optimally Windowed Chirps

Journal article Physical Review X · December 6, 2018 Featured Work The ability to measure the bulk dynamic behavior of soft materials with combined time and frequency resolution is instrumental for improving our fundamental understanding of connections between the microstructural dynamics and the macroscopic mechanical re ...

Thermal delay of drop coalescence

Journal article Journal of Fluid Mechanics · December 25, 2017 Featured Work We present the results of a combined experimental and theoretical study of drop coalescence in the presence of an initial temperature difference ΔT0 between a drop and a bath of the same liquid. We characterize experimentally the dependence of t ... Full text Cite

Thermokinematic memory and the thixotropic elasto-viscoplasticity of waxy crude oils

Journal article Journal of Rheology · May 1, 2017 Featured Work The effect of thermal and shear history on the rheology of waxy crude oils is studied in detail. A protocol sequence is presented, which enables us to systematically extract the main thixotropic features of a model waxy oil by a series of steady state and ... Full text Cite
