Journal ArticleDOI
Correlations of the nonexponentiality and state dependence of mechanical relaxations with bond connectivity in Ge-As-Se supercooled liquids.
Roland Böhmer,Charles Angell +1 more
TL;DR: The structural state dependence of the mechanical relaxation, detected in pure and weakly cross-linked Se, is suppressed completely at the rigidity percolation threshold, where the liquid fragility is a minimum.
Journal ArticleDOI
Nonresonant Spectral Hole Burning in the Slow Dielectric Response of Supercooled Liquids
TL;DR: In this paper, large-amplitude, low-frequency electric fields can be used to burn spectral holes in the dielectric response of supercooled propylene carbonate and glycerol.
Journal ArticleDOI
Dynamics of supercooled liquids and glassy solids
Journal ArticleDOI
Water's second glass transition.
Katrin Amann-Winkel,Catalin Gainaru,Philip H. Handle,Markus Seidl,Helge Nelson,Roland Böhmer,Thomas Loerting +6 more
TL;DR: It is reported that high-density amorphous ice at ambient pressure shows a distinct calorimetric glass transitions at 116 K and present evidence that this second glass transition involves liquid-like translational mobility of water molecules, related to the coexistence of two liquid phases.
Journal ArticleDOI
Structure and dynamics of monohydroxy alcohols—Milestones towards their microscopic understanding, 100 years after Debye
TL;DR: In this article, Debye devised a relaxation model for application to the dielectric properties of water and alcohols, which has been studied extensively because they are vital for biophysical processes, of fundamental importance as solvents in industrial processes and in every-day use.
