Misc

High-pressure SANS and NSE experiments in microemulsion systems, Michihiro Nagao, Youhei Kawabata, Hideki Seto, Review of High Pressure Science and Technology/Koatsuryoku No Kagaku To Gijutsu, 19, (1) 52 - 61,   2009 , 10.4131/jshpreview.19.52, http://ci.nii.ac.jp/naid/10024826679, Small-angle neutron scattering (SANS) and neutron spin echo (NSE) Spectroscopy have been used to elucidate static and dynamic structures of a microemulsion system composed of a nonionic surfactant, water, and oil. Using the contrast variation neutron scattering technique, static structure parameters are evaluated, and the molecular volume change with pressure is calculated. The bending elastic modulus increases with increasing pressure. This tendency is similar to the microemulsion system composed of anionic surfactant, water, and oil. Therefore, a universal feature of the surfactant membrane as a response to pressure is clarified, that is, the surfactant membrane becomes rigid at high pressure due to the increase of density of the hydrophobic tail of surfactant molecules and their aggregates.
Temperature- and pressure-dependence of nanometer scale structures in water/oil/surfactant systems, Hideki Seto, Michihiro Nagao, Youhei Kawabata, Review of High Pressure Science and Technology/Koatsuryoku No Kagaku To Gijutsu, 17, (2) 122 - 130,   2007 , 10.4131/jshpreview.17.122, http://ci.nii.ac.jp/naid/130000257505, Amphiphilic molecules conform nanometer-scale structures by adsorbing at oil and water interfaces or aggregating in water. The origins of forming such the structures are interesting issues to be solved not only for the field of soft-matter physics but also for neighbouring fields. In this viewpoint, the pressure-induced phase transitions of microemulsion systems composed of amphiphilic molecules, water and oil were investigated by means of small-angle neutron scattering, small-angle X-ray scattering, and neutron spin echo spectroscopy. The result shows that pressure mainly affects the interactions among hydrocarbon chains of amphiphilic molecules and/or between chains and surrounding oil molecules. This tendency is confirmed both in the cases of the ionic surfactant and of the non-ionic surfactant.
