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…
Switching of swimming modes in Magnetospirillium gryphiswaldense
Mathias Reufer, Rut Besseling, Jana Schwarz-Linek +6
The microaerophilic magnetotactic bacterium Magnetospirillum gryphiswaldense swims along magnetic field lines using a single flagellum at each cell pole. It is believed that this m…
Differential Dynamic Microscopy: a High-Throughput Method for Characterizing the Motility of Microorganism
Vincent A. Martinez, Rut Besseling, Ottavio A. Croze +6
We present a fast, high-throughput method for characterizing the motility of microorganisms in 3D based on standard imaging microscopy. Instead of tracking individual cells, we ana…
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…
