A New Approach to the Glass Transition of Percolated Polymers from the Perspective of Thermal Volume Expansion
Jan-Kristian Krüger, Bernd Wetzel, Andreas Klingler
In 1995, the Nobel Price winner P.W. Anderson made the following remarkable statement: The deepest and most interesting unsolved problem in solid state theory is probably the theor…

From the dynamic to the static glass transition via hypersonic measurements using Brillouin spectroscopy
Jan-Kristian Krüger, Rafael J. Jiménez Riobóo, Bernd Wetzel +1
For the fragile, low-molecular-weight liquid diglycidyl ether of bisphenol A (DGEBA), we report on the dynamic glass transition and a further acoustic anomaly in the vicinity of th…

Experimental determination of the glass transition temperature in a very narrow temperature range by Temperature Modulated Optical Refractometry
Andreas Klingler, Bernd Wetzel, Jan-Kristian Krueger
Latest since the landmark studies of Kovacs and co-workers on the glass transition of polymers, it is clear that thermally induced volume changes are of central importance for the…
