what is differential scanning calorimetry
The aim of this paper was to investigate pore-size distributions in the nano-diameter range of wood and their alteration due to thermal modification of wood using thermoporosimetry, and to find out what consequences can be derived regarding the biological durability. Thermoporosimetry is a technique that is based on the measurement using . A method is presented for estimating the strength distribution of noncovalent bondings in coal by use of differential scanning calorimetry (DSC) and thermogravimetry (TG). The idea of the method lies in the measurement of the enthalpy level of coal swollen by a nonpolar solvent, tetralin. The enthalpy level of tetralin-swollen coal, H i , is different from the . Calorimeters measure the heat consumed or released by a sample upon re-equilibration after a perturbation. Such perturbations can be caused by a change in temperature (differential scanning calorimetry), the addition of material (isothermal titration calorimetry) or a change in pressure (pressure perturbation calorimetry).

Differential Scanning Calorimetry is a thermoanalytical technique that measures the difference in the amount of heat required to increase the temperature of a sample, while also using a reference material that allows for comparison. It’s used for determining thermal information about a wide number of materials, including things like coatings . We have developed an analytical method to quantitatively analyze differential scanning calorimetry (DSC) experimental data. This method provides accurate determination of thermal properties such as equilibrium melting temperature, latent heat, change of heat capacity which can be performed automatically without intervention of a DSC operator. DSC is one of .Differential scanning calorimeters (DSC) are scientific instruments used in thermal analysis to measure the energy absorbed or released by a sample as it is heated or cooled. They are used by researchers, scientists, and engineers across many industries for precise measurement and analysis of thermal effects such as melting, crystallization, and glass transitions.
Differential scanning calorimetry determines the heat capacity of a sample at different temperatures by increasing (or decreasing) the temperature of a sample in a linear manner and measuring the power required to reach the required temperature. It can detect transitions within a sample which are associated with a change in heat capacity or a .

110 6 Applications of Differential Scanning Calorimetry Sometimes melting processes extend over very broad ranges oftemperature. For low molar mass substances this may be due to large amounts of impurities (cf. Sect. 6.2.4). For macromolecules this may be caused by the broad distribution of the Differential scanning calorimetry (DSC) is a technique used to study thermal transitions in polymers and other materials.
