DoS Dos and Don'ts
Lucas Warwaruk, Konstantinos Zinelis, Randy H. Ewoldt +2
Dripping-onto-Substrate (DoS) rheometry is a well-established method for measuring the extensional rheology of low-viscosity liquids. However, clear guidelines on the capabilities…
Egg yolk as a model for gelation: from rheometry to flow physics
Maxwell Marsh, Mohammad Tanver Hossain, Randy Ewoldt
Egg yolks are an excellent model for studying sol-gel transitions, particularly the power law viscoelasticity that defines the critical point of gelation. However, prior studies la…
Stretching the Printability Metric in Direct-ink Writing with Highly Extensible Yield-Stress Fluids
Chaimongkol Saengow, Samya Sen, Joaquin Yus +7
Direct-ink writing leverages the rheological complexity of yield-stress fluids to construct complex geometries, particularly those with large gaps across internal structures. Howev…
Stress-controlled medium-amplitude oscillatory shear (MAOStress) of PVA-Borax
Nabil Ramlawi, Mohammad Tanver Hossain, Abhishek Shetty +1
We report the first-ever complete measurement of MAOStress material functions, which reveal that stress can be more fundamental than strain or strain rate for understanding lineari…
Soft glassy materials with tunable extensibility
Samya Sen, Rubens R. Fernandes, Randy H. Ewoldt
Extensibility is beyond the paradigm of classical soft glassy materials, and more broadly, yield-stress fluids. Recently, model yield-stress fluids with significant extensibility h…
Distinguishing thixotropy, anti-thixotropy, and viscoelasticity using hysteresis
Yilin Wang, Randy H. Ewoldt
Thixotropy, anti-thixotropy, and viscoelasticity are three types of time-dependent dynamics that involve fundamentally different underlying physical processes. Yet distinguishing t…
