PhD project: Controlling the production of bijels by direct mixing.
A major breakthrough in soft matter physics was the demonstration that it was possible to create bicontinuous emulsions (bijels) stabilized by colloidal particles . Last year ourselves and others have shown that a similar structure can be made using much simpler approaches . These alternative approaches should make it easier to produce bijels using a diverse range of ingredients – hence a spectrum of experiments and applications would become possible. The physics behind this problem concerns the conditions under which a material, made up of two domains, switches over from having one domain continuous to having the other domain continuous. At the point at which the switch occurs the system either becomes a bijel or it becomes a multiple emulsion (forms droplets inside droplets). Both cases are fascinating.
In this project you will attempt to use the approaches demonstrated in  to show that they work with other combinations of liquids and particles. As well as demonstrating that other combinations are possible, this will lead to fundamental understanding of these new routes.
