Water-triggered conduction and polarization effects in a hygroscopic fullerene salt [PDF]

open access: yes, 2014
Impedance spectroscopy is employed to probe the frequency-dependent conductivity and dielectric response of the crystalline C60O24Na24 fulleride, both in its pure form obtained by heating to 473 K and in its bulk-hydrate form stable only below 390 K ...

The Hydration of Vimentin

open access: yesOphthalmic Research, 1993
The hydration of vimentin isolated from the cortex of bovine lenses was studied by thermal analysis. Differential scanning calorimetry between -30, and 30 degrees C provided the freezable water content, and thermogravimetric analysis up to 105 degrees C yielded the total water content. The difference between the two gives the nonfreezable water content
