A study of the effect of anaesthetic molecules on model membranes formed in surfactant / water mixtures
… of anaesthetic promotes changes in the membranes interfacial region or within their internal structure. The models used for biological membranes were simple surfactantiwater systems, which have been previously well studied and characterised. The phases they form are sensitive to changes in …

The effects of small molecules and polymer on the phase behaviour of C16EO16 - water mixture
… there is a loss of phases with high interfacial curvature and ultimately phase separation. The Mh i (R3m) phase is destabilised at low oil concentrations because the interlayer interaction is destabilised by the swelling of the alkyl chain region and the changing water layer …

Counterion identity effects on the self-assembly processes in a series of perfluorinated surfactant - water mixtures
… mesh (MJi 1 (0)) phase which possess non-uniform interfacial curvature. The second group of surfactants with counterions, butyltrimethylammonium (BTMA), dibutyldimetylammonium (DBDMA), and tetrabutylammonium (TBA), form only a classical lamellar phase (La). For both DBDMA and TBA lower consolute …

Molecular self assembly in flurocarbon surfactant / water systems
… and non-liquid crystalline) have uniform mean interfacial curvature. The phases observed are L 1 (vesicles), L. and L 2. With decreasing counterion hydrophobicity, the population of counterions associated with the interface decreases, introducing greater curvature into the system. The mean …

An experimental study of supercritical CO2 flow in pipes and porous micro-models for carbon sequestration applications
… events. In addition, the variations of the interfacial curvature with time and their connection with water flow field during the growth of fingers were studied. The results revealed the existence of high-momentum pathways in water ahead of growing CO2 fingers. After the passage of the CO2 …

On the Physics of Ice Nucleation and Growth in Nanoscale
… suppression of ice nucleation. Considering the interfacial deformation, the findings are in good agreement with predictions of classical nucleation theory. This understanding contributes to a greater knowledge of natural phenomena and rational design of anti-icing systems for aviation, wind …

Self-Organized Nanostructures from Stimuli-Responsive Triblock Terpolymers
… PDMAEMA chains provided control over the interfacial curvature of the aggregates and thus the micellar morphology. The solvent quality, the PDMAEMA block length, as well as the chain architecture, amount and functionality of the added multiacid were identified as major set screws. In a …

The Aggregation Behavior of Mixture of Alkylmethylaminoxides with Their Protonated Analogues in Aqueous Solution
… active than each component. The surface and interfacial measurements showed synergism of mixing two components. This synergistic effect arised from the peculiar interaction of hydrogen bonding between protonated and non-protonated head groups. This short-range interaction would cause the …

Crystalline Morphologies of Poly(butadiene)-b-Poly(ethylene oxide) Block Copolymers in n-Heptane
… PB coronar chains. This triggers the onset of an interfacial instability, therefore the spherical micelles preferred to reorganize into a morphology with a smaller interfacial curvature. The low crystallinity of the PEO core imposed a stronger tendency of the rods to aggregate and to thicken into …
