Shape anisotropy enhances the elasticity of colloidal gels through mechanisms that act multiplicatively
Peng-Kai Kao, Michael J. Solomon, Mahesh Ganesan
The physical gelation of colloids produces elastic structures that are commonly used to stabilize complex fluids in multiple industries. However, the ability to control the level o…
Elasticity of colloidal gels: structural heterogeneity, foppy modes, and rigidity
D. Zeb Rocklin, Lilian C. Hsiao, Megan Szakasits +2
Rheological measurements of model colloidal gels reveal that large variations in the shear moduli as colloidal volume-fraction changes are not reflected by simple structural parame…
Capillary-driven binding of thin triangular prisms at fluid interfaces
Joseph A. Ferrar, Deshpreet S. Bedi, Shangnan Zhou +3
We observe capillary-driven binding between thin, equilateral triangular prisms at a flat air-water interface. The edge length of the equilateral triangle face is 120 , and the…
A rheological state diagram for rough colloids in shear flow
Lilian C. Hsiao, Safa Jamali, Daniel J. Beltran-Villegas +4
The flow of dense suspensions, glasses, and granular materials is heavily influenced by frictional interactions between constituent particles. However, neither hydrodynamics nor fr…
Variable Viscosity and Density Biofilm Simulations using an Immersed Boundary Method, Part II: Experimental Validation and the Heterogeneous Rheology-IBM
Jay A. Stotsky, Jason F. Hammond, Leonid Pavlovsky +4
The goal of this work is to develop a numerical simulation that accurately captures the biomechanical response of bacterial biofilms and their associated extracellular matrix (ECM)…
A model colloidal gel for coordinated measurements of force, structure, and rheology
Lilian C. Hsiao, Kathryn A. Whitaker, Michael J. Solomon +1
We introduce a model gel system in which colloidal forces, structure, and rheology are measured by balancing the requirements of rheological and microscopy techniques with those of…
