During the second cooling, an inflection in the temperature curve may occur. Such an inflection could be ascribed to the detachment of the polymer from the heating device that, on its turn, determines a reduction of the heat transfer and a decrease of the cooling rate. The faster the cooling...
The monotonous increase character of the blue curve in Fig. 2c suggests that, during growth, the Quartz crystal gradually rotates over the same axis, with a small rotation angle between neighboring points, but a much larger accumulated rotation angle for a longer distance. The above mentioned ...

The endothermic peaks revealed by the DTA curve at 122 °C reflects the dehydration process and is in agreement with findings by Zubowa et al. and Huo et al.8, 17. At about 970 °C there is an exothermic peak which testifies the transformation into a new phase. Figure 6 DTA-TG ...
The proposed model accounts for the deviations of brines from the marine evaporitic evolution curve by brine mixing, rather than due to a change in ocean chemistry. It also explains the absence of bittern minerals in the thick halite and gypsum/anhydrite succession, and the compositional gap ...
Although the theoretical curve involving this 84 Polymer J., Vol. 1, No. 1, 1970 Spherulitic Growth Rate of Isotactic Polystyrene -3.0 ~---3.5 ro< 108cm/hr) proposed by these authors. It is obvious that Eq. 4 does not fit at all the experimental data represented in Figure 3. The ...
The TGA curve shapes are gentle, and they do not show sharp peaks. This is evidence of a low-crystallinity material and an extremely variable composition at the micron scale so that the dehydroxylation reactions occur in a temperature range rather than at one defined T°. The only other ...
