Two cloud-point phenomena in tetrabutylammonium perfluorooctanoate aqueous solutions: Anomalous temperature-induced phase and structure transitions
Article Abstract:
The phase behavior and aggregate structure of tetrabutylammonium perfluorooctanoate (TBPFO), determined by differential scanning calorimeter, electrical conductivity, static/dynamic light scattering, and rheology methods is reported. It was found that above a certain concentration, the TBPFO solution showed anomalous temperature-dependant phase behavior and structure transitions, which meant that such an ionic surfactant solution exhibits two cloud-points.

Effect of guest hydrophobicity on water sorption behavior of oligomeric/[alpha]-cyclodextrin inclusion complexes
Article Abstract:
Complementary water vapor sorption and wide-angle X-ray diffractomery (WAXD) are performed on oligomer/[alpha]cyclodextrin ([alpha]-CD) inclusion complexes (ICs) in order to determine their structures and stabilities. Polyethylene glycol (PEG) and hexatriacontane (HTC) guests are used to examine the effect of guest molecule hydrophobicity on water adsorption isotherms.
