Phase separation in miscible polymer blends as detected by modulated temperature differential scanning calorimetry
TLDR

Restricted chain segment mobility in poly(amide) 6/clay nanocomposites evidenced by quasi-isothermal crystallization
TL;DR: In this paper, a modulated temperature differential scanning calorimetry is used to explore the interactions between a poly(amide) 6 matrix and various types of clay reinforcement during quasi-isothermal crystallization of the polymer/clay nanocomposites, an excess contribution is observed in the recorded heat capacity signal, due to reversible melting and crystallization.

Modulated differential scanning calorimetry
TL;DR: ModModulated DSCTM (MDSC) as mentioned in this paper is a new extension to conventional DSC which provides information about the reversing and nonreversing characteristics of thermal events, as well as the ability to directly measure heat capacity.

Modulated differential scanning calorimeter
TL;DR: In this article, a modulated differential scanning calorimeter (MDSC) and a method for practicing MDSC that uses two separate temperature difference signals (the difference between the temperatures of the sample and reference positions and the difference between temperatures between the sample position and a base position) are presented.
