On the origins of apparent fragile-to-strong transition of protein hydration waters
Michael Vogel
2H NMR is used to study the mechanisms for the reorientation of protein hydration water. In the past, crossovers in temperature-dependent correlation times were reported at T_x1=22…
Conformational and Structural Relaxations of Poly(ethylene oxide) and Poly(propylene oxide) Melts: Molecular Dynamics Study of Spatial Heterogeneity, Cooperativity, and Correlated Forward-Backward Motion
Michael Vogel
Performing molecular dynamics simulations for all-atom models, we characterize the conformational and structural relaxations of poly(ethylene oxide) and poly(propylene oxide) melts…
Ion and polymer dynamics in polymer electrolytes PPO-LiClO4: II. 2H and 7Li NMR stimulated-echo experiment
Michael Vogel, Thorsten Torbruegge
We use 2H NMR stimulated-echo spectroscopy to measure two-time correlation functions characterizing the polymer segmental motion in polymer electrolytes PPO-LiClO4 near the glass t…
Ion and polymer dynamics in polymer electrolytes PPO-LiClO4: insights from NMR line-shape analysis
M. Vogel, T. Thorbrugge
We investigate ion and polymer dynamics in polymer electrolytes PPO-LiClO4 performing 2H and 7Li NMR line-shape analysis. Comparison of temperature dependent 7Li and 2H NMR spectra…
Temperature dependence of spatially heterogeneous dynamics in a model of viscous silica
M. Vogel, S. C. Glotzer
Molecular dynamics simulations are performed to study spatially heterogeneous dynamics in a model of viscous silica above and below the critical temperature of the mode coupling th…
A complete identification of lithium sites in a model of LiPO glass: effects of the local structure and energy landscape on ionic jump dynamics
Michael Vogel
We perform molecular dynamics simulations to study lithium dynamics in a model of LiPO glass at temperatures below the glass transition. A straightforward analysis of the ionic…
