Molecular Dynamics and Charge Transport in highly-conductive Polymeric Ionic Liquids

Glassy dynamics and charge transport are studied for the polymeric ionic liquid (PIL) poly[tris(2-(2-methoxyethoxy)ethyl)ammonium acryloxypropyl sulfonate] (PAAPS) with varying molecular weight (9700, 44200, 51600, and 99500 g/mol) by broadband dielectric spectroscopy (BDS) in a wide frequency (10−2−107 Hz) and temperature range (100−400 K) and by DSC- and AC-chip calorimetry.

The dielectric spectra are characterized by a superposition of (i) relaxation processes, (ii) charge transport, and (iii) electrode polarization. Continue reading “Talk by F. Frenzel at UL (October 24, 2017)”

3rd iRTG Workshop (November 20-21, 2017)


This workshop addresses doctoral students in chemistry, physics, biophysics, and related fields in the iRTG “Polymers: random coils and beyond”. The doctoral students will introduce the basic theoretical and technical concepts necessary for an understanding of projects within the iRTG. The iRTG workshop focuses on experimental and theoretical techniques to study synthetic polymer and biopolymer systems. Continue reading “3rd iRTG Workshop (November 20-21, 2017)”

International PhD Meeting, October 13th 2017

On October 13, 2017, the International Office and the International Gra- duate Academy InGrA will organize via the PhD Network this year’s Welcome Meeting “International PhD Meeting 2017”.
The meeting is intended for doctoral candidates who just started with their doctorate as well as for those who are already further along with their thesis.

The event aims at greeting newcomers, giving information about first steps at Martin Luther University Halle-Wittenberg and in the city of Halle and at introducing consultation and support services at the university. Doctoral candidates who are in the middle of their doctorate or who are about to finish their dissertation will be given information on the admission to and the process of the doctoral procedure at the respective faculty. Also, there will be room for the participants to ask questions and to get in contact with each other about topics relevant to their PhD.
