Effect of water on the dispersion of colloidal alumina in cyclohexane solutions of Aerosol OT

Solvent-specific gel-like transition via complexation of polyelectrolyte and hydroxyapatite nanoparticles suspended in water–glycerin mixtures: a rheological study

“…In view of these expected changes with glycerol addition, one possibility for the origin of the observed rheological behavior might be similar to the ''water-bridging'' mechanism that occurs for suspensions of mineral particles in organic media on addition of a small amount of water. [44][45][46] This hypothesis is also consistent with the high viscosities observed in the water-based suspensions [Fig. 5(b)].…”

Effect of Temperature on the Mobility of Nitroxide Probes in Cyclohexane and at the Alumina–Cyclohexane Interface

“…In such cases t values were estithat adsorption of water causes conformational changes in the adsorbed aerosol-OT layer at the alumina-cyclohexane mated using the following method of calculation (22). interface (19). This observation was consistent with changes observed in the stability of these dispersions.…”

Investigation of the mobility of amphiphilic polymer—AOT reverse microemulsion systems using electron spin resonance

“…The probe chosen was 5-doxyl stearic acid which has been studied previously with similar AOT reverse microemulsions [41][42][43][44] and is known to position itself at the watersurfactant interface with the nitroxide free radical located in the AOT hydrocarbon tail region.…”

“…In addition, a simplified method [41] was used to extract the order parameter, S, from the EPR spectra in cases where a good agreement with the S values derived from simulations (using the program by Budil and Freed) was observed.…”
