WebIn more than 300 DTA/DSC studies of Tg published over a period of 2005-2006 the authors specified the way of Tg determinations only in 68 publications. 70% of these authors used point A, 20% point B and 10% point C. In about 250 papers (out of 300) the way of Tg determination was not specified. At the same time, as is seen from the caption to ...
WebDSC plots for dry sucrose and trehalose. In some cases the Tg zone was accompanied by an enthalpic relaxation (ΔH relax). This phenomenon occurs when the amorphous molecules reorient themselves to a lower energy amorphous state. Since this relaxation is made possible by the onset of glass transition, it does not affect the onset of glass ...
