The hexagonally-packed clusters of DPPC chains that are present at low temperatures melt upon heating at T co , which leads to a change in the temperature dependencies of many structural and dynamic properties. Interestingly, the dependence below and above the crossover was different for the binary and ternary mixtures, yet they converged towards each other at low and high temperatures. The properties of the binary mixture were more different on the two sides of the crossover temperature, highlighting that DOPC is able to buffer many properties in the ternary mixture. Still, all studied properties change continuously with temperature, and no radical changes akin to a 1 st order phase transition were observed.
