Yield precursor in primary creep of colloidal gels
Jae Hyung Cho, Irmgard Bischofberger
Predicting the time-dependent yielding of colloidal gels under constant stress enables control of their mechanical stability and transport. Using rotational rheometry, we show that…
Lasting effects of discontinuous shear thickening in cornstarch suspensions upon flow cessation
Jae Hyung Cho, Andrew H. Griese, Ivo R. Peters +1
Dense suspensions that exhibit discontinuous shear thickening (DST) undergo complex stress relaxation when the flow abruptly stops. Using rotational rheometry, we study the two-ste…
Perspectives on viscoelastic flow instabilities and elastic turbulence
Sujit S. Datta, Arezoo M. Ardekani, Paulo E. Arratia +20
Viscoelastic fluids are a common subclass of rheologically complex materials that are encountered in diverse fields from biology to polymer processing. Often the flows of viscoelas…
Single-shot quantitative polarization imaging of complex birefringent structure dynamics
Baoliang Ge, Qing Zhang, Rui Zhang +8
Polarization light microscopes are powerful tools for probing molecular order and orientation in birefringent materials. While a multitude of polarization light microscopy techniqu…
Two Modes of Cluster Dynamics Govern the Viscoelasticity of Colloidal Gels
Jae Hyung Cho, Irmgard Bischofberger
Colloidal gels formed by strongly attractive particles at low particle volume fractions are composed of space-spanning networks of uniformly sized clusters. We study the thermal fl…
