Anomalous Scaling for Hydrodynamic Lubrication of Conformal Surfaces
James A. Richards, Patrick B. Warren, Daniel J. M. Hodgson +2
The hydrodynamic regime of the Stribeck curve giving the friction coefficient as a function of the dimensionless relative sliding speed (the Sommerfeld number, ) of two cont…
Gap-Dependent Hydrodynamic Lubrication in Conformal Contacts
James A. Richards, Patrick B. Warren, Wilson C. K. Poon
We show that the hydrodynamic lubrication of contacting conformal surfaces with a typical texture height gives rise to a universal behaviour in the Stribeck curve in which the fric…
Sizing multimodal suspensions with differential dynamic microscopy
Joe J Bradley, Vincent A Martinez, Jochen Arlt +2
Differential dynamic microscopy (DDM) can be used to extract mean particle size from videos of suspensions. However, many suspensions have multimodal particle size distributions (P…
Hydrodynamic Stability Criterion for Colloidal Gelation under Gravity
Joost de Graaf, Kim William Torre, Wilson C. K. Poon +1
Attractive colloids diffuse and aggregate to form gels, solid-like particle networks suspended in a fluid. Gravity is known to strongly impact the stability of gels once they are f…
Characterization and Control of the Run-and-Tumble Dynamics of {\it Escherichia Coli}
Christina Kurzthaler, Yongfeng Zhao, Nan Zhou +8
We characterize the full spatiotemporal gait of populations of swimming {\it Escherichia coli} using renewal processes to analyze the measurements of intermediate scattering functi…
Quantitative characterization of run-and-tumble statistics in bulk bacterial suspensions
Yongfeng Zhao, Christina Kurzthaler, Nan Zhou +8
We introduce a numerical method to extract the parameters of run-and-tumble dynamics from experimental measurements of the intermediate scattering function. We show that proceeding…
