abstract = {Currently, the design of microemulsions is focussed on the
formulation of environmentally compatible systems formed by
non-harmful amphiphiles and oils. The use of sugar-based
surfactants allows the design of microemulsions where,
instead of the temperature, the addition of short- or
medium-chain alcohols tunes the curvature of the amphiphilic
interface. In this work, the resulting temperature stability
of a sugar surfactant and rapeseed methyl ester based
bicontinuous microemulsion is exploited to study the
influence of temperature variations on the bending elastic
constant κ. Quasi-elastic scattering of light and neutrons
is used to separate long-range collective motions and local
thermally excited undulations of the interface. κ in units
of kT is found to be independent of temperature over a wide
range.},
