Detection of the liquid-liquid transition in the deeply cooled water confined in MCM-41 with elastic neutron scattering technique
Zhe Wang, Kanae Ito, Sow-Hsin Chen
In this paper we present a review on our recent experimental investigations into the phase behavior of the deeply cooled water confined in a nanoporous silica material, MCM-41, wit…
Unusual Phase Behavior of Confined Heavy Water
Yang Zhang, Antonio Faraone, William A. Kamitakahara +5
Many of the anomalous properties of water are amplified in the deeply supercooled region. Here we present neutron scattering measurements of the density of heavy water confined in…
Logarithmic decay in single-particle relaxations of hydrated lysozyme powder
Marco Lagi, Piero Baglioni, Sow-Hsin Chen
We present the self-dynamics of protein amino acids of hydrated lysozyme powder around the physiological temperature by means of molecular dynamics (MD) simulations. The self-inter…
Observation of the Density Minimum in Deeply Supercooled Confined Water
Dazhi Liu, Yang Zhang, Chia-Cheng Chen +3
Small angle neutron scattering (SANS) is used to measure the density of heavy water contained in 1-D cylindrical pores of mesoporous silica material MCM-41-S-15, with pores of diam…
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…
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…
