Behaviour and Assembly of Janus Particles in Confined Systems — •Julie Murison and Matthias Schröter — Max Planck Insitute of Dynamics and Self Organization, Göttingen

Half hydrophobic Janus Particles were created using a pickering-style emulsion. The degree of Hydrophobicity was controlled using different surfactants to create a portfolio of beads. Self Assembly of these particles at the air/water and oil/water interfaces was studied using X-ray Tomography. Beads are found to form micelle like structures within the bulk and create distinct regions of wettability. The packings are useful to model natural porous systems of heterogeneous wettability such as petroleum reservoirs.
