Caruthers, J. M.; Medvedev, G. A. published an article in 2018, the title of the article was Quantitative model of super-Arrhenian behavior in glass forming materials.HPLC of Formula: 118-55-8 And the article contains the following content:
The key feature of glass forming liquids is the super-Arrhenian temperature dependence of the mobility, where the mobility can increase by ten orders of magnitude or more as the temperature is decreased if crystallization does not intervene. A fundamental description of the super-Arrhenian behavior has been developed; specifically, the logarithm of the relaxation time is a linear function of 1/Ux, where Ux is the independently determined excess molar internal energy and B is a material constant This one-parameter mobility model quant. describes data for 21 glass forming materials, which are all the materials where there are sufficient exptl. data for anal. The effect of pressure on the loga mobility is also described using the same Ux(T,p) function determined from the difference between the liquid and crystalline internal energies. It is also shown that B is well correlated with the heat of fusion. The prediction of the B/Ux model is compared to the Adam and Gibbs 1/TSx model, where the B/Ux model is significantly better in unifying the full complement of mobility data. The implications of the B/Ux model for the development of a fundamental description of glass are discussed. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).HPLC of Formula: 118-55-8
