Rheofluidics: frequency-dependent rheology of single drops
Matteo Milani, Wenyun Wang, Lorenzo Russotto +4
We present Rheofluidics, a microfluidic technique that measures the frequency-dependent rheology of individual micron-scale objects. We apply oscillatory hydrodynamic stresses by f…
Ductile-to-brittle transition and yielding in soft amorphous materials: perspectives and open questions
Thibaut Divoux, Elisabeth Agoritsas, Stefano Aime +37
Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays and cementitious pastes to emulsions and physical gels encountered in food or biomedical e…
Anomalous crystalline ordering of particles in a viscoelastic fluid under high shear
Sijie Sun, Nan Xue, Stefano Aime +5
Addition of particles to a viscoelastic suspension dramatically alters the properties of the mixture, particularly when it is sheared or otherwise processed. Shear-induced stretchi…
A unified state diagram for the yielding transition of soft colloids
Stefano Aime, Domenico Truzzolillo, David J. Pine +2
Concentrated colloidal suspensions and emulsions are amorphous soft solids, widespread in technological and industrial applications and studied as model systems in physics and mate…
Probing shear-induced rearrangements in Fourier Space. II. Differential Dynamic Microscopy
Stefano Aime, Luca Cipelletti
We discuss in two companion papers (arXiv:1802.03737 and the present manuscript) how Fourier-space measurements may be coupled to rheological tests in order to elucidate the relati…
Microscopic dynamics and failure precursors of a gel under mechanical load
Stefano Aime, Laurence Ramos, Luca Cipelletti
Material failure is ubiquitous, with implications from geology to everyday life and material science. It often involves sudden, unpredictable events, with little or no macroscopica…
Probing shear-induced rearrangements in Fourier Space. I. Dynamic Light Scattering
Stefano Aime, Luca Cipelletti
Understanding the microscopic origin of the rheological behavior of soft matter is a long-lasting endeavour. While early efforts concentrated mainly on the relationship between rhe…
Power law viscoelasticity of a fractal colloidal gel
Stefano Aime, Luca Cipelletti, Laurence Ramos
Power law rheology is of widespread occurrence in complex materials that are characterized by the presence of a very broad range of microstructural length and time scales. Although…
A stress-controlled shear cell for small-angle light scattering and microscopy
S. Aime, L. Ramos, J. -M. Fromental +3
We develop and thoroughly test a stress-controlled, parallel plates shear cell that can be coupled to an optical microscope or a small angle light scattering setup, for simultaneou…
An efficient scheme for sampling fast dynamics at a low average data acquisition rate
A. Philippe, S. Aime, V. Roger +4
We introduce a temporal scheme for data sampling, based on a variable delay between two successive data acquisitions. The scheme is designed so as to reduce the average data flow r…
