Another interesting feature of this extended p-sheet model can be seen in Figure 3b, where we show the effect of temperature on the CD spectrum of Peptide 5. Curiously, when the sample temperature is decreased (to 5 C), the spectrum takes on more of a "random coil character (only 20% p-sheet) but, when the temperature is increased to 85 C, the spectrum exhibits significantly more P-sheet character (38% p-sheet). In other words, high temperatures induce structure and cold temperatures reduce structure. We believe that this represents an excellent example of cold denaturation (19), and it suggests that the thermodynamics of p-sheet formation may be more complex than currently appreciated. 

On the other hand, hysteresis of the temperature-induced structural phase transitions in nanostructures with first-order phase transitions reduce useful magnetocaloric effect to transform cycling between martensite (M) and austenite (A) phases under application. In addition, the size, surface and boundary effects on thermal hysteresis loops have been under consideration for the development of research on nanostructured materials. Experimental data indicate that nanostructured materials offer many interesting prospects for the magnetization data and for understanding of temperature-induced martensite/austenite phase transitions. 

Unlike aqueous solutions, a typical Arrhenius dependence for the reverse systems is maintained only before a certain critical temperature (T ), while above this temperature a decrease in occurs with tanperature. The value of is found to coincide with the percolation threshold temperature. We assume that the same temperature induced structural changes of the reverse micelles are responsible for the clnstering of the reverse... 

Another important class of studies is to investigate temperature-induced structural transitions. This has been performed for the metal Be. At ambient pressure. Be transforms from a low temperature hexagonal close-packed (hep) structure to a high temperature body-centered cubic (bcc) structure at approximately 1530 K before it melts at about 1560 This transition is interesting in several...

As in the case of electric field induced structural transition, the temperature induced structural transition is also associated with critical slowing down of the director fluctuations. However, as reorientation of the droplet director can occur along any direction in the xy plane, both 6n ey and 6n ex fundamental modes exhibit a critical behaviour of 1/ro in the vicinity of Tc and consequently a slowing down detected in the dynamic light scattering experiments is more pronounced than in case of electric field induced transition.
