The slow secondary (β) process of 1,1′-bis (4-methoxyphenyl) cyclohexane and phenolphthalein dimethylether has been investigated by dielectric spectroscopy. New experimental results about the pressure dependence of the two ...

We report evidence from broadband dielectric spectroscopy that the dynamics of the primary α- and secondary Johari−Goldstein (JG) β-processes are strongly correlated in different glass-forming systems over a wide temperature T and pressure P range...

The relationship between structural and secondary dynamics is one of the most recently considered and possibly important issues of the dynamics in glass formers. One relation of interest is the ratio between the activation energy of the secondary...
