Determination of viscoelastic properties with TMA, DMTA and DSC
Thermochimica Acta, 1985Abstract Viscoelastic properties mainly determine the application possibilities of polymers. Because of the generally high sensitivity required to see changes in the elastic properties, thermomechanical methods become increasingly important compared to calorimetric methods. On a sample of thermoplastic PU, and a unidirectional carbon fibre reinforced

Curing of a thermosetting powder coating by means of DMTA, TMA and DSC
Polymer, 2003Abstract The curing of a thermosetting powder coating made up of carboxyl-terminated polyester and triglycidylisocyanurate (TGIC) was studied by means of dynamic mechanical thermal analysis (DMTA), thermal mechanical analysis (TMA) and differential scanning calorimetry (DSC). On the basis of isothermal curing of the coating on different supports with

DMTA study of the urethane network in rubber waste-urethane composites
Journal of Thermal Analysis and Calorimetry, 2005The supermolecular structures of rubber waste-urethane composites based on results of mechanical spectroscopy are discussed. The results give a broader understanding of the relation between the processing history and the morphology in the resultant engineering products.

Investigation on PA/PP mixture properties by means of DMTA method
Journal of Materials Processing Technology, 2006Abstract Polymer mixing is presently one of the most effective and the most intensely developing methods of physical properties modification for polymers. Mixing polymers one can modify certain properties, mainly physical. In this work, investigation results for mixtures of polyamide 6 with polypropylene have been presented.

Examination of Thermodynamic Realignments of Metals and Metal-Alloys, by DMTA Technique
Materials Science Forum, 2015The researcher work pushes the borders of the application of a high efficiency equipment, in the matter of metals. With this equipment, which already testified in the compound industry, a flasher query of some metal-related technological parameters could be easily available.

The use of DMTA for predicting standard mechanical properties of developmental polyolefins
Journal of Thermal Analysis and Calorimetry, 2009The correlation of linear data from dynamic-mechanical testing (DMTA) to nonlinear data from standard mechanical testing was attempted for a number of quite different polypropylene-based compositions. For limited composition ranges, correlations between storage modulus and stiffness as well as between loss angle integrals and impact strength could be ...

Investigations of wood veneer during furfuryl alcohol modification using DMTA
European Journal of Wood and Wood Products, 2015Dynamic mechanical thermal analysis has been used to monitor the change in wood veneer stiffness due to furfuryl alcohol impregnation and plasticization of wood components and subsequent polymerization of furfuryl alcohol within wood material. This explains the improvement in the moulding ability of wood veneer where furfuryl alcohol aids in wood ...

DNA methylation is an important epigenetic modification that depends on DNA methyltransferases (DMT). However, the filamentous fungus Aspergillus flavus has no detectable methylation, and role of a DMT homologue, DmtA, is undefined. Here we describe the role of the dmtA gene responding to changes in the environment by comparing knockout, point mutation,
