Abstract. Chip-based fast scanning calorimetry (FSC) or chip-calorimetry based on MEMS-sensor technology nowadays enables constant heating and cooling rates from 10 2 up to more than 10 9 K/min on micro- to nanogram samples, respectively, as measured between − 150 and 1000 °C. Evidently, fast processes – like applied in production during cooling – can now be .

7.5.1 Differential scanning calorimetry. Differential scanning calorimetry (DSC) is a direct analytical experimental technique that measures the heat flux ∂ q / ∂ t to or from a sample specimen as well as enthalpy changes as a function of temperature or time. This method is not a passive experimental technique because there is a change of .In this updated and fully revised second edition, the authors provide the newcomer and the experienced practitioner with a balanced and comprehensive insight into all important methods and aspects of Differential Scanning Calorimetry (DSC), including a sound presentation of the theoretical basis of DSC thermal analysis and temperature-modulated DSC (TMDCS).
Gelatinization characteristics of laboratory-isolated and commercial corn starch were compared by differential scanning calorimetry (DSC) before and after being annealed at subgelatinization temperatures in excess water. Prior to annealing, commercial corn starch has a relatively narrow gelatinization range, with a peak temperature at 71°C. Starches isolated in the laboratory have .
