Contrast variation Small-angle neutron scattering (CV-SANS) will be used to probe structure of novel organogels made from surfactants and p-halophenols as low molecular weight organogelators (LMOGs, Figure 2). Both the LMOG and the surfactant are commercially available. There is no literature on CV-SANS on these systems. Alongside this, the use of halophenols brings phase transition temperature of the gels to an appropriate temperature region (Figure 3), and forms stronger gels than the hydrocarbon phenols previously documented 1-2, increasing their potential for use with CO2-philic surfactants.
