Application of dense microemulsions to magnetic resonance imaging
Roe, Jo; Ramanan, Deva; Hornak, Joseph; Kotlarchyk, Michael (Elsevier Science B.V., Amsterdam, 1996-09-15)Microemulsions have recently been proposed as the signal-bearing solution for use in a magnetic resonance imaging phantom. We have attempted to characterize the hydrogen nuclear spin system of paramagnetically doped water, ... -
Attractive interactions in micelles and microemulsions
Huang, John; Saffran, Samuel; Grest, Gary; Kotlarchyk, Michael; Quirke, Nick (American Physical Society, 1984-08-06)We have used small-angle neutron scattering to study surfactant interactions in an inverted micellar and a related microemulsions system. The structure-factor fits imply an attractive interaction between micelles with a ... -
Critical behavior of a microemulsion studied by small-angle neutron scattering
Kotlarchyk, Michael; Chen, Sow-Hsin; Huang, John (American Physical Society, 1983-07)The critical behavior of a three-component water-in-oil microemulsion was studied by small-angle neutron scattering. Intensity spectra were analyzed by the treatment of critical scattering as arising from concentration ... -
Isomeric and concentration effects of C4-cosurfactants on four-component microemulsions investigated by neutron spin-echo and small-angle scattering
Zambrano, Elvis; Kotlarchyk, Michael; Langner, Andreas; Faraone, Antonio (Institute of Physics and IOP Publishing Limited, 2006-08-24)Neutron spin-echo spectroscopy and small-angle scattering measurements were performed to determine how the isomeric structure and concentration of C4-cosurfactants (i.e. butyl alcohols) influence structure and dynamics in ... -
Paracrystal model of the high-temperature lamellar phase of a ternary microemulsion system
Kotlarchyk, Michael; Ritzau, S. (Blackwell Publishing : Journal of Applied Crystallography, 1991-10-01)Small-angle neutron scattering was used to investigate the microstructure of the high-temperature L-alpha phase in the AOT/water/decane system [AOT = sodium bis(2-ethylhexyl) sulfosuccinate]. The system was modeled as ... -
Structural and dynamical transformations between neighboring dense microemulsion phases
Kotlarchyk, Michael; Sheu, Eric; Capel, Malcolm (American Physical Society, 1992-07-15)A small-angle x-ray scattering (SAXS) study of dense AOT-water-decane microemulsions [AOT denotes sodium bis(2-ethylhexyl) sulfosuccinate] was undertaken in order to delineate clearly the phase behavior and corresponding ... -
Structure of Dense Sodium Di-2-Ethylsulfosuccinate/D2O/Decane Microemulsions
Kotlarchyk, Michael; Chen, Sow-Hsin; Huang, John; Kim, Mahn Won (American Physical Society, 1984-08-27)Small-angle neutron scattering is used to investigate the structure of single-phase AOT (sodium di-2-ethylsulfosuccinate)/D2O/decane microemulsions containing equal volumes of water and oil and a variable concentration of ... -
Structure of three-component microemulsions in the critical region determined by small-angle neutron scattering
Kotlarchyk, Michael; Chen, Sow-Hsin; Huang, John; Kim, Mahn Won (American Physical Society, 1984-04)The intensity distribution of the critical scattering from sodium di-2-ethylhexylsulfosuccinate AOT-D2O-n-alkane water-in-oil (W/O) microemulsions has been measured over an extensive range of droplet volume fractions (3-30 ... -
Study of interfacial curvature in a three-component microemulsion with equal volumes of water and oil
Huang, John; Kotlarchyk, Michael (American Physical Society, 1986-11-17)We have used a double-contrast-variation method in small-angle neutron scattering to study the structure of a single-phase microemulsion containing equal amounts of oil (decane) and water stabilized with an aerosol OT ... -
Study of Schultz distribution to model polydispersity of microemulsion droplets
Kotlarchyk, Michael; Stephens, Richard; Huang, John (American Chemical Society, 1988-03-24)We have employed a histogram analysis method to study the spectra obtained by small-angle neutron scattering (SANS) in order to investigate the size distribution of a model water-in-oil three-component microemulsion. It ...
