Conching chocolate: A prototypical transition from frictionally jammed solid to flowable suspension with maximal solid content
Elena Blanco, Daniel J. M. Hodgson, Michiel Hermes +6
The mixing of a powder of 10-50μm primary particles into a liquid to form a dispersion with the highest possible solid content is a common industrial operation. Building on recent…
Dynamic mode locking in a driven colloidal system: experiments and theory
Michael P. N. Juniper, Urs Zimmermann, Arthur V. Straube +4
In this article we examine the dynamics of a colloidal particle driven by a modulated force over a sinusoidal optical potential energy landscape. Coupling between the competing fre…
Dilatancy in the flow and fracture of stretched colloidal suspensions
M. I. Smith, R. Besseling, M. E. Cates +1
Concentrated particulate suspensions, commonplace in the pharmaceutical, cosmetic and food industries, display intriguing rheology. In particular, the dramatic increase in viscosit…
Shear banding and flow-concentration coupling in colloidal glasses
R. Besseling, L. Isa, P. Ballesta +3
We report experiments on hard sphere colloidal glasses that reveal a type of shear banding hitherto unobserved in soft glasses. We present a scenario that relates this to an instab…
Quantitative imaging of concentrated suspensions under flow
Lucio Isa, Rut Besseling, Andrew B Schofield +1
We review recent advances in imaging the flow of concentrated suspensions, focussing on the use of confocal microscopy to obtain time-resolved information on the single-particle le…
Quantitative imaging of colloidal flows
Lucio Isa, Rut Besseling, Eric R. Weeks +1
We present recent advances in the instrumentation and analysis methods for quantitative imaging of concentrated colloidal suspensions under flow. After a brief review of colloidal…
