Lithium-salt-based deep eutectic solvents: Importance of glass formation and rotation-translation coupling for the ionic charge transport
A. Schulz, P. Lunkenheimer, A. Loidl
Lithium-salt-based deep eutectic solvents, where the only cation is Li+, are promising candidates as electrolytes in electrochemical energy-storage devices like batteries. We have…
Translational and reorientational dynamics in deep eutectic solvents
D. Reuter, P. Münzner, C. Gainaru +3
We performed rheological measurements of the typical deep eutectic solvents (DESs) glyceline, ethaline, and reline in a very broad temperature and dynamic range, extending from the…
Supercooled water confined in a metal-organic framework
Jonas K. H. Fischer, Pit Sippel, Dmytro Denysenko +3
Within the so-called "no-man's land" between about 150 and 235 K, crystallization of bulk water is inevitable. The glasslike freezing and a liquid-to-liquid transition of water, pr…
Ionic conductivity of deep eutectic solvents: The role of orientational dynamics and glassy freezing
D. Reuter, C. Binder, P. Lunkenheimer +1
We have performed a thorough examination of the reorientational relaxation dynamics and the ionic charge transport of three typical deep eutectic solvents, ethaline, glyceline and…
Importance of reorientational dynamics for the charge transport in ionic liquids
P. Sippel, S. Krohns, D. Reuter +2
Most ionic liquids contain at least one rather complex ion species exhibiting a dipolar moment. In the present work, we provide a thorough evaluation of broadband dielectric spectr…
Johari-Goldstein relaxation far below Tg: Experimental evidence for the Gardner transition in structural glasses?
K. Geirhos, P. Lunkenheimer, A. Loidl
Experimental evidence for the Gardner transition, theoretically predicted to arise deep in the glassy state of matter, is scarce. At this transition, the energy landscape sensed by…
Variation of ionic conductivity in a plastic-crystalline mixture
D. Reuter, C. Geiß, P. Lunkenheimer +1
Ionically-conducting plastic crystals are possible candidates for solid-state electrolytes in energy-storage devices. Interestingly, the admixture of larger molecules to the most p…
Dielectric study on mixtures of ionic liquids
E. Thoms, P. Sippel, D. Reuter +3
Ionic liquids are promising candidates for electrolytes in energy-storage systems. We demonstrate that mixing two ionic liquids allows to precisely tune their physical properties,…
Dynamics of Protein Hydration Water
M. Wolf, S. Emmert, R. Gulich +2
We present the frequency- and temperature-dependent dielectric properties of lysozyme solutions in a broad concentration regime, measured at subzero temperatures and compare the re…
Relaxation dynamics of a protein solution investigated by dielectric spectroscopy
M. Wolf, R. Gulich, P. Lunkenheimer +1
In the present work, we provide a dielectric study on two differently concentrated aqueous lysozyme solutions in the frequency range from 1 MHz to 40 GHz and for temperatures from…
'Boson peak' and high-frequency excitations in glassy crystals
P. Lunkenheimer, A. Loidl
The high-frequency excitations in glasses and supercooled liquids belong to the great mysteries of the physics of condensed matter. While the fast process, located at GHz-THz, can…
