Phase Transition of Cholesteryl Acetylferulate

Effect of Electron Irradiation on the Thermodynamical and Optical Properties of Cholesteryl Pelargonate

“…These values of the different transi-tion temperatures of the pure sample agree well with literature data [18,19]. [14]. The above data show that electron beam irradiation is more damaging than -irradiation.…”

“…The typical DSC thermograms showing the variations of the heat flow (mW) with temperature (°C) at a scan rate of 5 ºC/min in the heating and cooling cycles are shown in The phase transition temperatures increase linearly with the increasing scan rate [14][15][16]. Fig.…”

The supramolecular self-organization of an amphotropic cholesterol derivative Micelles, liposomes and liquid-crystalline phases

“…crystals. Attempts to prepare these so-called ordered glasses from non-polymeric liquid crystals by rapid cooling are not new, but in most systems these glasses undergo recrystallization upon heating (see, for example, [18][19][20]). The cholesterol derivative 1 shows a completely reversible glass transition (with preservation of order in the glassy state), which is independent of the cooling rate.…”

Dielectric relaxation studies in n-(4-octyloxy-2-hydroxybenzylidene)-4-carbethoxyaniline

“…Such an effect can be assigned to thermal resistance between the material and the oven (DSCCatalogue, 1988). In many other materials studied so far (Kunihisa and Satomi, 1986;Srivastava et al, 1993;Pandey et al, 2004), transition temperatures obtained in the heating and cooling cycles have been found to agree at the extrapolated scanning rate of 0 C min À1 (in the case of enantiotropic transitions), which can be supposed to FIGURE 1 Linear dependence of peak temperatures of different transitions with the scanning rate. be the transition temperature recorded under the condition of virtual thermal equilibrium.…”
