Pressure Dependence of the Dynamic Crossover Temperatures in Protein and its Hydration Water
Xiang-qiang Chu, Antonio Faraone, Chansoo Kim +4
Recently we have shown experimental evidence for a fragile-to-strong dynamic crossover (FSC) phenomenon in hydration water around a globular protein (lysozyme) at ambient pressure.…
Observation of a Dynamic Crossover in RNA Hydration Water which Triggers the Glass Transition in the Biopolymer
Xiang-qiang Chu, Emiliano Fratini, Piero Baglioni +2
High-resolution quasi-elastic neutron scattering spectroscopy was used to measure H2O and D2O hydrated RNA samples. The contribution of scattering from RNA was subtracted out by ta…
The Violation of Stokes-Einstein Relation in Supercooled Water
Sow-Hsin Chen, Francesco Mallamace, Chung-Yuan Mou +4
By confining water in nanopores, so narrow that the liquid cannot freeze, it is possible to explore its properties well below its homogeneous nucleation temperature TH ~ 235 K. In…
Observation of Fragile-to-Strong Dynamic Crossover in Protein Hydration Water
Sow-Hsin Chen, Li Liu, Emiliano Fratini +3
At low temperatures proteins exist in a glassy state, a state which has no conformational flexibility and shows no biological functions. In a hydrated protein, at and above 220 K,…
Experimental Evidence of Fragile-to-Strong Dynamic Crossover in DNA Hydration Water
Sow-Hsin Chen, Li Liu, Xiangqiang Chu +5
We used high-resolution quasielastic neutron scattering spectroscopy to study the single-particle dynamics of water molecules on the surface of hydrated DNA samples. Both H2O and D…
Pressure Dependence of Fragile-to-Strong Transition and a Possible Second Critical Point in Supercooled Confined Water
Li Liu, Sow-Hsin Chen, Antonio Faraone +2
By confining water in nano-pores of silica glass, we can bypass the crystallization and study the pressure effect on the dynamical behavior in deeply supercooled state using neutro…
