Differential thennal analysis

Standard test method for assignment of the glass-transition temperatures hy differential scanning calorimetry or differential-thennal analysis Methods of test for determination of glass-transition temperature of electrical insulating materials... 

Differential thennal analysis (DTA) or a similar technique called differential scanning calorimetry (DSC) can be used to determine the temperature at which phase transitions such as glass transition temperature and melting temperature T occur. DTA involves heating a polymer sample along widi... 

Boyle et al. [318] have used real-time diffraction at a synchrotron source for following the effect of heat treatment of various doped PANIs. The x-ray data are supplemented by mass spectroscopy, thennal gravimetry and differential thermal analysis data. The authors consider PANI-HCl, PANI-HCIO4 and PANl-H2SO4, as well as a sample free of dopant but containing water. Diffraction patterns are decomposed into Gaussian peaks in order to describe the evolution... 

ASTM E 793-79 Heats of Fusion and Crystallization by Differential Scanning Calorimetry. [1-37] ASTM E 794-85 Melting and Crystallization Temperatures by Thennal Analysis. 

III lieal iraiisler analysis, vve are often iiitetested in the rate of heat transfer through a medium under steady conditions and surface temperatures. Such problems can be solved easily without involving any differential equations by (he introduction of the iheimal resislance concept in an analogous manner to electrical circuit problems. In this case, the thennal resistance corresponds to electrical resistance, temperature difference corresponds to voltage, and the heat transfer rate coiresponds to electric current.
