Colloidal rods in optical potential energy landscapes

Joshua L Abbott, James A Spiers, Yongxiang Gao, Dirk GAL Aarts, and Roel PA Dullens

J. Phys. D: Appl. Phys 2019 52 024002

We study the static and dynamic behaviour of colloidal rods in an optical potential energy landscape. We explore the stable states of a colloidal rod in a single optical trap close to a flat wall. Her ...

Capillary nematisation of colloidal rods in confinement

Kira E Klop, Roel PA Dullens, Paul M Lettinga, Sergei A Sergei, and Dirk GAL Aarts

We confine a colloidal liquid crystal between parallel plates separated down to several times the rod length. By connecting the system to a reservoir we effectively create a grand canonical system, in ...

Bulk synthesis of silver-head colloidal rodlike micromotors

Yongxiang Gao, Roel PA Dullens, and Dirk GAL Aarts

Structure factors in a two-dimensional binary colloidal hard sphere system

Alice L Thorneywork, Simon K Schnyder, Dirk GAL Aarts, Juergen Horbach, Roland Roth, and Roel PA Dullens

Mol. Phys. 2018 116 3245

Hard disks are one of the simplest interacting many-body model system in two dimensions (2D). Here, we present a comprehensive set of measurements of the static structure factors for quasi-2D monodisp ...
