Structure of AOT reverse micelles under shear.
Reverse micelles in the AOT/water/isooctane system, at various water contents (W(0)), were studied using rheometry and small angle X-ray scattering (SAXS) experiments under static conditions and under shear. The SAXS analysis confirmed the spherical shape of the micelles at low water content and revealed a transition into elongated micelles at higher water content. A population of spherical mic...
متن کاملWater dynamics at the interface in AOT reverse micelles.
The orientational dynamics of water molecules at the interface in large Aerosol-OT (AOT) reverse micelles are investigated using ultrafast infrared spectroscopy of the OD stretch of dilute HOD in H(2)O. In large reverse micelles ( approximately 9 nm diameter or larger), a significant amount of the nanoscopic water is sufficiently distant from the interface that it displays bulk-like characteris...
متن کاملStructure modifications of AOT reverse micelles due to protein incorporation.
Structural modifications of AOT/water/isooctane reverse micelles due to incorporation of proteins were studied at various water contents and protein concentrations, using small-angle X-ray scattering (SAXS) experiments under static conditions, rheometry analysis, and SR-SAXS experiments under induced shear flow. Two proteins, lysozyme (pI 11.1, Mw 14,300 Da) and BSA (pI 4.3, Mw 66,700 Da), were...
متن کاملUltrafast energy transfer in water-AOT reverse micelles.
A spectroscopic investigation of the vibrational dynamics of water in a geometrically confined environment is presented. Reverse micelles of the ternary microemulsion H2O/AOT/n-octane (AOT = bis-2-ethylhexyl sulfosuccinate or aerosol-OT) with diameters ranging from 1 to 10 nm are used as a model system for nanoscopic water droplets surrounded by a soft-matter boundary. Femtosecond nonlinear inf...
متن کاملTo probe the structure of methanol and Aerosol OT (AOT) in AOT reverse micelles by FTIR measurements.
We have reported the study of methanol/AOT/n-heptane reverse micellar aggregates using Fourier Transform Infrared (FTIR) spectroscopy. We have divided our whole work into two parts. In the first part we have studied the structural properties of Aerosol OT (AOT) reverse micelles by monitoring the changes in the symmetrical sulfonate stretching region (1000-1100 cm(-1)), asymmetrical sulfonate st...
