Event details
It is often desirable to mix two components that don't like to be
mixed, like oil and water. This can be achieved by using a third
stabilising component and suspending one phase in the other. These
so-called emulsions surround us in everyday life. Mayonnaise and paint
are common emulsions. Generally they occur widely in the
pharmaceutical, food, cosmetic, oil and recycling industry.
Stratford et al [1] have presented computer simulations which suggest
a novel type of emulsion can be obtained by exploiting the spinodal
phase separation kinetics of demixing liquids.
This then results in an interconnected bicontinuous emulsion which has
many new exciting material properties.
After a long and painful process we have now achieved the creation of
these 3-dimensional super-emulsions experimentally. I will show why
they are unique compared to already available materials and endeavour
to justify why it is interesting to study them from a scientific point
of view.

About Condensed Matter lunchtime seminars
This is a weekly series of informal talks given primarily by members of the institute of condensed matter and complex systems, 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..
