Relating Capillary Suspension Morphology to Deformation Response

Short Abstract Colloidal or particle suspensions are important for a wide range of applications and industrial processes, from food stuffs and personal care products to powder processing and oil extraction methods; the latter are important for the petroleum field. One of the key problems with studying capillary suspensions is the ability to measure forces and displacements while visualizing capillary bridges and particle organization – this makes it challenging to connect forces and displacements to the changing morphology. In this proposal, we propose to investigate how the capillary bridges relate to measured forces of particle suspensions starting with single bridges, followed by multi-bridge particle chains, while visualizing the bridge shapes and particle organizations.
