Dielectric studies of tetraethylene glycol-bis(3-methylimidazolium) dichloride (TEGDC) exhibiting large negative dielectric anisotropy
Article Abstract:
A dielectric anisotropy property of a TEGDC (tetraethylene glycol-bis(3-methylimidazolium) dichloride) is investigated as a function of frequency. Variation of dielectric anisotropy with respect to spot frequencies reveals that liquid crystal orientation has an n-type property at low frequencies and as the frequency increases dielectric anisotropy character shifts from negative to positive dielectric anisotropy.

Spectroscopic and computational studies of aqueous ethylene glycol solution surfaces
Article Abstract:
The combination of Monte Carlo, ab initio, and DFT computational studies of ethylene glycol (EG) and EG-water hydrogen-bonding complexes indicate that experimental vibrational spectra of EG and EG-water solution surfaces have contributions from numerous conformations of both EG and EG-water. The change indicates that EG behaves as a hydrogen-bond acceptor when solvated by additional water molecules.

Molecular mechanism of the photochemical generation of gold nanoparticles in ethylene glycol: Support for the disproportionation mechanism
Article Abstract:
A study found that replacement of the chloride ions in tetrachloroauric acid with bulky bromide ions inhibits the formation of gold nanoparticles in the photochemical reduction in ethylene glycol. However, the addition of silver ions to either the bromide or the chloride auric acid solution is found to enhance the rate of gold nanoparticle formation.
