Anomalous Shear Stress Growth During Relaxation of a Soft Glass
Crystal E. Owens
We show experimentally that multiple soft glassy fluids are capable of storing directional rheological signatures from past shear history, evidenced during stress growth and overal…
Computational Rheometry of Yielding and Viscoplastic Flow in Vane-and-Cup Rheometer Fixtures
Emad Chaparian, Crystal E. Owens, Gareth H. McKinley
A planar two-dimensional computational analysis is presented to qualify traditional and fractal vane-in-cup geometries for accurate rheometry of simple viscoplastic fluids with and…
Improved Rheometry of Yield Stress Fluids Using Bespoke Fractal 3D Printed Vanes
Crystal E. Owens, A. John Hart, Gareth H. McKinley
To enable robust rheological measurements of the properties of yield stress fluids, we introduce a class of modified vane fixtures with fractal-like cross-sectional structures. A g…
Highly Parallel Acoustic Assembly of Microparticles into Well-Ordered Colloidal Crystallites
Crystal E. Owens, C. Wyatt Shields, Daniela F. Cruz +2
The precise arrangement of microscopic objects is critical to the development of functional materials and ornately patterned surfaces. Here, we present an acoustics-based method fo…
