Thermal microscopy

Characterization and control of interfaces in the incompatible polymer blends were reported by Fayt et al. [23]. They used techniques such as electron microscopy, thermal transition analysis, and nonradiative energy transfer (NRET), etc. They have illustrated the exciting potentialities offered by diblock copolymers in high-performance polymer blends. 

Of all the methods available for the physical characterization of solid materials, it is generally agreed that crystallography, microscopy, thermal analysis, solubility studies, vibrational spectroscopy, and nuclear magnetic resonance are the most useful for characterization of polymorphs and solvates. However, it cannot be overemphasized that the defining criterion for the existence of polymorphic types must always be a non-equivalence of crystal structures. For compounds of pharmaceutical interest, this ordinarily implies that a non-equivalent X-ray powder diffraction pattern is observed for each suspected polymorphic variation. All other methodologies must be considered as sources of supporting and ancillary information, but cannot be taken as definitive proof for the existence of polymorphism by themselves.

For example, the most commonly used thermal method is and will almost certainly continue to be differential scanning calorimetry (DSC), hence here we have dedicated three chapters to the technique covering the principles, the optimal use of the method, and pharmaceutical applications. We then include chapters on thermo-gravimetric analysis, modulated temperature DSC, microcalorimetry, high sensitivity DSC, thermal microscopy, thermally stimulated current, and dynamic mechanical analysis, all of which have attracted great interest within the pharmaceutical field. In all cases, these chapters combine elements of theoretical background, measurement optimization, and pharmaceutical applications. It is our profound hope that in this way we will achieve a suitable mixture of depth, relevance, and accessibility. 

The study of polymorphs and solvates begins with the methods used to elucidate the nature of the system in question. Beginning with the basic arsenal of crystallography, microscopy, thermal analysis, solubil-... 

The miscibility can be studied by various techniques, such as differential scanning calorimetry, electron microscopy, thermal mechanical analysis, and viscometry. Miscible blends exhibit a single glass transition temperature. Viscometry is an effective, quick, and inexpensive technique to elucidate polymer/polymer interactions. 

All samples were first analyzed by optical microscopy. Thermal treatment was also performed under the optical microscope. The samples were placed onto an enclosed hotplate, purged with nitrogen, under a Leitz-Metallux...

This book covers a wide range of lectures given at the Short Summer Course celebrated at La Laguna University about the new trends in the modern characterization methods chemical, microscopies, thermal. X-ray, resonance and nuclear methos for ceramics, glasses and related materials. This book also looks also at the zeolite thermal characterization methods as well as the new approaches in new microscopies for the investigation of surfaces in materials.
