Abstract:
An approach to assess the ionic liquid (IL) dynamic fragility is discussed in this work; for this, viscosity data (a transport property) of 48 ILs of different classes (aprotic, protic, surfactant and magnetic) were surveyed. The fitting approach taken here enables, for the most part, IL-viscosity data at relatively mild to moderate temperatures for precise reproduction of experimentally resolved glass transition temperatures (T g). This, in turn, suggests that ILs are likely to be intermediate between strong- and highly fragile liquids - analogous to ionic inorganic melts such as ZnCl2, Ca(NO3)2·4H2O, or CKN (mixture of calcium and potassium nitrates).

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
