Experimental Realization of the Green-Kubo Relation in Colloidal Suspensions Enabled by Image-based Stress Measurements
Neil Y. C. Lin, Matthew Bierbaum, Itai Cohen
By combining confocal microscopy and Stress Assessment from Local Structural Anisotropy (SALSA), we directly measure stresses in 3D quiescent colloidal liquids. Our non-invasive an…
How Confinement-Induced Structures Alter the Contribution of Hydrodynamic and Short-Ranged Repulsion Forces to the Viscosity of Colloidal Suspensions
Meera Ramaswamy, Neil Y. C. Lin, Brian D. Leahy +4
Understanding the correlation between structure and rheology in colloidal suspensions is important as these suspensions are crucial in industrial applications. Moreover, colloids e…
Relating Microstructure and Particle-level Stress in Colloidal Crystals Under Increased Confinement
Neil Y. C. Lin, Itai Cohen
The mechanical properties of crystalline materials can be substantially modified under confinement. Such modified macroscopic properties are usually governed by the altered microst…
A multi-axis confocal rheoscope for studying shear flow of structured fluids
Neil Y. C. Lin, Jonathan H. McCoy, Xiang Cheng +3
We present a new design for a confocal rheoscope that enables uniform uniaxial or biaxial shear. The design consists of two precisely-positioned parallel plates with a gap that can…
Tunable Shear Thickening in Suspensions
Neil Y. C. Lin, Christopher Ness, Michael E. Cates +2
Shear thickening, an increase of viscosity with shear rate, is a ubiquitous phenomena in suspended materials that has implications for broad technological applications. Controlling…
Hydrodynamic and contact contributions to shear thickening in colloidal suspensions
Neil Y. C. Lin, Ben M. Guy, Michiel Hermes +4
Shear thickening is a widespread phenomenon in suspension flow that, despite sustained study, is still the subject of much debate. The longstanding view that shear thickening is du…
Far-from-equilibrium Sheared Colloidal Liquids: Disentangling Relaxation, Advection, and Shear-induced Diffusion
Neil Y. C Lin, Sushmit Goyal, Xiang Cheng +3
Using high-speed confocal microscopy, we measure the particle positions in a colloidal suspension under large amplitude oscillatory shear. Using the particle positions we quantify…
Bi-axial shear of confined colloidal suspensions: the structure and rheology of the vorticity-aligned string phase
Neil Y. Lin, Xiang Cheng, Itai Cohen
Using a novel bi-axial confocal rheoscope, we investigate the structure and rheology of sheared colloidal suspensions under confinement. Consistent with previous work [X. Cheng \te…
