Talk by E. Schreck at MLU (6th December 2016)

Polymers on Surfaces – or how to catch them all

The talk  will feature recent developments in the lab. It focuses mainly on the preparation of thinnest polymer films / single molecules under UHV condition. It introduces the techniques quadrupole mass spectrometry (QMS), quartz microbalance (QMB) and scanning tunneling microscopy (STM) and how their results should lead to a successful preparation. A short overview of what is coming next will be given at the end of the talk.

Location: MLU Halle-Wittenberg, Von-Danckelmann-Platz 3, SR 1.03, 06120 Halle (Saale)
Date and time: 06.12.16 at 3.30pm

Talk by P. Leube at UL (29th November 2016)

Characterization of the multiresponsive Poly(N,N-dimethylaminoethyl methacrylate) by spin probing EPR spectroscopy

The still rising number of publications dealing with stimuli-responsive polymers prove the high interest in such smart materials. Poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA) exhibits thermo-, pH- and ionic strength responsive behavior in aqueous solutions, being a multiresponsive homopolymer [1]. The goal of this study is to under- stand, how the pH and ionic strength affect the thermoresponsivity of PDMAEMA.

Molecular dynamics simulations of polyQ14: structural and spectroscopic parameters

Polyglutamine proteins (PolyQ) are members of a big family of intrinsically disordered proteins or IDPs. Very flexible as monomers in solutions PolyQs tend to aggregate and form amyloid fibrils which were shown to be neurodegenerative. [1]

Amyloid Beta Aggregation in the Presence of Temperature-Sensitive Polymers

The formation of amyloid fibrils is considered to be one of the main causes for many neurodegenerative diseases, such as Alzheimer’s, Parkinson’s or Huntington’s disease [1]. Current knowledge suggests that amyloid-aggregation represents a nucleation-dependent aggregation process in vitro, where a sigmoidal growth phase follows an induction period. Here, we studied the fibrillation of amyloid β 1-40 (Aβ40) in the presence of thermoresponsive polymers, expected to alter the Aβ40 fibrillation kinetics due to their lower critical solution behavior [2-6].
