DSC is capable of heating a given material at a controlled rate ... which is a phenomenon that occurs when the amorphous polymer chains form abnormally denser regions within the sample. The ...

Figure 11. DSC scan of PET after quench cooling Figure 12. DSC scan of PET after slow cooling Having a well-defined T g means that the quenched material has a significant amorphous structure, which ...

There are numerous techniques available to quantify moderate-to-high levels of amorphous material in powders. Some of these techniques include differential scanning calorimetry (DSC), density, powder ...

The amorphous state of matter is the most abundant form of visible matter in the universe, and includes all structurally disordered systems, such as biological cells or essential materials like ...

For glass transition or softening of amorphous material, this is as anticipated. In Figure 2a, the plots provide a least-squares fit of the LTA onset measurements attained at the three heating rates ...

Similar to polymorphs, we find that amorphous materials can take on several modifications ... thermal analysis like differential scanning calorimetry (DSC), and more sophisticated techniques ...

The advanced DSC technologies allow accurate characterization of a wide range of amorphous and crystalline pharmaceutical materials including tablets, proteins, and frozen solutions. TGA exploits ...

Our data suggest that as SACs transition from an orientationally disordered structure to an ordered one, the phonon mean free paths, and hence the thermal conductivity of the material, will ...

differential scanning calorimetry (DSC), or any other suitable method. Obviously, if a material is amorphous, it has no crystal structure, but most milled powders have only a small (<5% w/w) amorphous ...

Unlike crystalline solids, where atoms line up in an orderly grid, amorphous materials are a molecular jumble. This disorder can boost solubility dramatically, but it comes at a cost: instability.
