AbstractThe effect of alternating the parameters of the heating program on the signal of StepScan DSC was studied. In this study samples were amorphous spray-dried lactose. The heating program includes two different states. In the first state, the heating state, sample is heated small temperature increments by some known heating rate. The second state, the isothermal state, includes a short isothermal time interval in which the sample reaches a thermal equilibrium.
The heating of soil during fires may result in organic matter loss. The ratio of combustion enthalpy of soil organic matter to the alpha-beta quartz transition enthalpy can be used to compare heated and unheated soil. This eliminates the need to weigh samples and is insensitive to differences in water content between heated and unheated soils, making possible in-situ applications in field sites.READ MORE
