Temperature dependence of the electrical conductivity of imidazolium ionic liquids.
The electrical conductivities of 1-alkyl-3-methylimidazolium tetrafluoroborate ionic liquids and of 1-hexyl-3-methylimidazolium ionic liquids with different anions were determined in the temperature range between 123 and 393 K on the basis of dielectric measurements in the frequency range from 1 to 10^7 Hz. Most of the ionic liquids form a glass and the conductivity values obey the Vogel-Fulcher-Tammann equation. The glass transition temperatures are increasing with increasing length of the alkyl chain. The fragility is weakly dependent on the alkyl chain length but is highly sensitive to the structure of the anion.ionic liquids; molten salts;
Wasting Breath in Hamlet
This is the final version. Available on open access from Palgrave via the DOI in this recordThis chapter draws on instances of disordered breathing in
Hamlet in order to examine the cultural signifcance of sighs in the early
modern period, as well as in the context of current work in the feld
of medical humanities. Tracing the medical history of sighing in ancient
and early modern treatises of the passions, the chapter argues that sighs,
in the text and the performance of the tragedy, exceed their conventional
interpretation as symptoms of pain and disrupt meaning on the page and
on stage. In the light of New Materialist theory, the air circulating in
Hamlet is shown to dismantle narratives of representation, posing new
questions for the future of medical humanities
