"Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature … See more There are two main types of DSC: Heat-flux DSC which measures the difference in heat flux between the sample and a reference (which gives it the alternative name Multi-Cell DSC) and Power differential DSC … See more An alternative technique, which shares much in common with DSC, is differential thermal analysis (DTA). In this technique it is the heat flow to the sample and reference that remains the same rather than the temperature. When the sample and reference are … See more Differential scanning calorimetry can be used to measure a number of characteristic properties of a sample. Using this technique it is possible to observe See more • Chemical thermodynamics • Calorimetry • Endothermic • Exothermic • Forensic engineering See more The basic principle underlying this technique is that when the sample undergoes a physical transformation such as phase transitions, more or less heat will need to flow to it … See more The result of a DSC experiment is a curve of heat flux versus temperature or versus time. There are two different conventions: exothermic reactions in the sample shown with a positive or … See more The technique is widely used across a range of applications, both as a routine quality test and as a research tool.

WebSyntax-free computation (Format-free computation) Syntax-free (or format-free) math computation is a novel software technology that allows users to input equations as in a notebook free of computational syntax; the software program interprets what equation inputs are, and works out how to complete computations for these equations. WebDSC is a useful tool for studying this phenomenon known as “physical aging”. The initial DSC heating scan of physically aged polymers commonly reveals an endothermic peak near the trailing edge of the Tg step-change. This peak is referred to as the “enthalpy of relaxation” or “enthalpic recovery” (ΔH R ).
