Differential Scanning Calorimetry (DSC)

2008
Physical and chemical changes may often be induced by raising or lowering the temperature of a substance. Typical examples are phase transitions, such as fusion, or chemical reactions, such as the solid state polymerization of sodium chloroacetate, which has an onset at 471 K: ClCH2COONa (cr) ⇋ NaCl (cr) + 1/n − (CH2COO)n − (pol) Differential scanning ...

Differential Scanning Calorimetry of Proteins

1995
Differential scanning calorimetry (DSC) is a powerful technique to characterize temperature-induced conformational changes in proteins and other biological macromolecules. In fact, DSC studies on protein thermal denaturation have played a central role in the development of current views about the factors that determine protein stability. Reviews on the

Differential Scanning Calorimetry

1984
The purpose of this paper is to review briefly the technique of differential scanning calorimetry (1), and to indicate how it may be used to determine enthalpies of phase change and of certain chemical reactions.

Differential scanning calorimetry and temperature-modulated differential scanning calorimetry: an extension to lower temperatures

High Temperatures-High Pressures, 2000
Temperature-modulated differential scanning calorimetry (TMDSC) has become a versatile technique for determining the specific heat (c p ) properties of condensed matter, but commercial instruments do not allow TMDSC measurements below 130 K. A top-loading cryostat incorporated within a commercial TMDSC instrument is presented, which allows c p ...

Biochemical Applications of Differential Scanning Calorimetry

Annual Review of Physical Chemistry, 1987
Differential scanning calorimetry (DSC) and the closely related differential thermal analysis (DTA) have been widely employed during the last several decades in the thermodynamic study of processes that are initiated by either an increase or a decrease in temperature. This review focuses on biochemical applications of DSC.

Quantitative Differential Scanning Calorimetry [PDF]

, 1978
Even relatively crude methods of thermal analysis, typified by scaleless ordinales, have proved of great value in polymer characterisation; the presence or absence of a peak is often sufficient to infer what structure is present and hence what the ultimate properties will be.

Differential Scanning Calorimetry of Polyurethanes

1968
The urethane linkage results from the reaction of an isocyanate group and a hydroxyl group and has the structure \( \left( {\begin{array}{*{20}{c}} H&O&{} \\ |&{||}&{} \\ { - N - }&{C - }&{O - } \end{array}} \right) \). Polymers containing this linkage are referred to as polyurethanes although the term has also been applied to polymers containing ...

Compatibility of Differential Scanning Calorimetry and ac Calorimetry

Japanese Journal of Applied Physics, 1994
In the simultaneous measurement of heat capacity by differential scanning calorimetry and ac calorimetry using the same apparatus with ac temperature modulation superposed on a linear temperature ramp, the principle of measurement by ac calorimetry is not sufficiently understood yet.

Differential Scanning Calorimetry of Protein–Lipid Interactions

2012
Differential scanning calorimetry (DSC) is a highly sensitive nonperturbing technique used for studying the thermodynamic properties of thermally induced transitions. Since these properties might be affected by ligand binding, DSC is particularly useful for the characterization of protein interactions with biomimetic membranes.

Differentiation of lard and tallow by differential scanning calorimetry

Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1972
The solidification curve of lard and tallow of various origins has been studied by DSC (differential scanning calorimetry). There is a very pronounced difference in the solidification pattern of both fats. All tallow samples showed a very important solidification minimum at a high temperature.
