1. X-Ray Investigations of the Liquid-Liquid Critical Point Hypothesis in Supercooled Water
Sammanfattning : This thesis presents experimental x-ray scattering studies on supercooled liquid water. A liquid-liquid transition between two structurally distinct configurations has been found in deeply supercooled water, indicating the existence of a liquid- liquid critical point. LÄS MER
2. The Role of Molecular Heterogeneity in the Structural Dynamics of Aqueous Solutions
Sammanfattning : The liquid-liquid critical point hypothesis suggests that liquid water exists in two liquid states with different local structures, so-called high- and low-density liquid (HDL, LDL). At ambient pressure water locally fluctuates between these two states, with the fluctuations becoming more pronounced as the liquid is supercooled. LÄS MER
