Elastic Characteristics

Gelling carrageenans are polysaccharides extracted from the Gigartinales order of red algae. These are additives used essentially in the food industry for texturizing, stabilizing or gelling various formulations. Although a consensual gel mechanism has been reached which encompasses a coil-to-helix transition followed by the self-assembling of helices in a network, the structure–elastic relationships in the network are still to be clearly established. This paper reviews the reports in which carrageenan gel structures have been systematically compared with gel elastic properties. The focus is on the sizes documented for structural units, such as strands, aggregates, voids or network meshes, as well as on the reported linear and nonlinear elastic characteristics. The insufficient rationalization of carrageenan gel elasticity by models which take on board mechanically relevant structural features is underlined. After introducing selected linear and nonlinear elastic models, preliminary results comparing such models to structural and rheological data are presented. In particular, the concentration scaling of the strain hardening exhibited by two types of carrageenan gels is discussed.

The results of studies of shear elastic properties of a high-temperature superconducting (HTSC) of YBa2Cu3O7 - x ceramics in the vicinity of the phase transition to the superconducting state at at a temperature of 91.3 K, as well as at room temperature of 293 K are presented. For the first time, a local increase in the shear nonlinear acoustic parameter N was investigated. Experimental studies of the linear and nonlinear elastic properties of HTSC ceramics YBa2Cu3O7 - x in the region of the superconducting transition showed that the electronic phase transition has significant influence on its elastic properties. Based on the results of experimental measurements linear and nonlinear elastic parameters were determined both at room temperature and in the region phase transition temperature.
