Confined Water as Model of Supercooled Water
TL;DR: None of the proposed scenarios is able to predict all the observations for supercooled and glassy bulk water, indicating that either the structural and dynamical alterations of confined water are too severe to make predictions for bulk water or the differences in how the studied water has been prepared are too large for direct and quantitative comparisons.
Journal ArticleDOI
Dynamics of Water Intercalated in Graphite Oxide
TL;DR: In this article, broadband dielectric spectroscopy (BDS) was used to investigate the intercalated water in graphite oxide (GO) by using different techniques, such as differential scanning calorimetry, X-ray diffraction, and attenuated total reflection geometry in FTIR.
Journal ArticleDOI
Glass transition and relaxation processes in supercooled water
TL;DR: Evidence is found that the dielectric relaxation process of confined water that has been associated with the long accepted T(g) of water (130-140 K) must be a local process which is not related to the actual glass transition.
Journal ArticleDOI
Universal features of water dynamics in solutions of hydrophilic polymers, biopolymers, and small glass-forming materials
Silvina Cerveny,Silvina Cerveny,Angel Alegría,Angel Alegría,Juan Colmenero,Juan Colmenero,Juan Colmenero +6 more
TL;DR: A systematic investigation by dielectric spectroscopy of 18 different water-rich mixtures with very different hydrophilic substances shows universal features for the water dynamics that suggest that the observed crossover is associated with the emergence of confinement effects.
Journal ArticleDOI
Permanent adsorption of organic solvents in graphite oxide and its effect on the thermal exfoliation

TL;DR: In this article, the dispersion of graphite oxide (GO) in organic solvents followed by their evaporation at relative high temperature resulted in a strong adsorption of the solvent molecules in the graphitic interlayers as confirmed by 13C magic-angle-spinning NMR.
