Overall, these results are consistent with the observations of LC-LE-Gas coexistence at low temperatures and the mixing of LE and LC phases at the critical point of temperature. The growth of LC domains with decreasing temperature leads to close packing of lipids and increased density in the LC region. This induces a decrease in domain boundaries and low lipid density in the LE region, tending to create a gas phase. As the temperature increases, LC domains melt, increasing the lipid density in the LE region, and eventually leading to the mixing of LC and LE phases at the critical point.
