The presence of ethanol can lead to the formations of non-lamellar phases also known as non-bilayer phases. Ethanol has been recognized as being an excellent solvent in an aqueous solution for inducing non-lamellar phases in phospholipids. The formation of non-lamellar phases in phospholipids is not completely understood, but it is significant ...
Solid–liquid phase change of ethanol–water mixtures Sodium chloride and water form a eutectic mixture whose eutectic point is −21.2 °C [ 8 ] and 23.3% salt by mass. [ 9 ] The eutectic nature of salt and water is exploited when salt is spread on roads to aid snow removal , or mixed with ice to produce low temperatures (for example, in ...
Lipid molecules in the HII phase pack inversely to the packing observed in the hexagonal I phase described above. This phase has the polar head groups on the inside and the hydrophobic, hydrocarbon tails on the outside in solution. The packing ratio for this phase is larger than one, [1] which is synonymous with an inverse cone packing.
The solid phase is commonly referred to as a “gel” phase. All lipids have a characteristic temperature at which they undergo a transition from the gel to liquid phase. In both phases the lipid molecules are constrained to the two dimensional plane of the membrane, but in liquid phase bilayers the molecules diffuse freely within this plane.
Increasing the amphiphile concentration beyond the point where lamellar phases are formed would lead to the formation of the inverse topology lyotropic phases, namely the inverse cubic phases, the inverse hexagonal columnar phase (columns of water encapsulated by amphiphiles, (H II) and the inverse micellar cubic phase (a bulk liquid crystal ...

In multilamellar liposomes, many such lipid bilayer sheets are layered concentrically with water layers in between. Figure 1 Multi-lamellar phase of aqueous lipid dispersions, each white lamella represents a lipid bilayer organization in liposome made by vortex-mixing of dried total lipid extract of spinach thylakoid membranes with distilled water.
