The principle strength of the bijel is thus that it can bring two immiscible and independently flowing solvents into intimate contact across a porous membrane. This makes the bijel a contender for a range of chemical and biochemical applications, including extractions, reactions and trace analysis.
In order for this to happen, however, the bijel first needs to exist. Eva Herzig made the first fully three-dimensional bijel less than two years ago; since then, we've learnt quite a lot about how to make it (and how not to). In this talk I'll run over some of the ways in which the bijel is and is not robust, and show some encouraging preliminary results on flowing solvents through it. A warning: the surface chemistry of the colloidal particles used to make the bijel turns out to be crucial. However, any mention of actual chemicals or their structures will quickly be followed by some diverting movies.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
