1. 1. X-Ray Investigations of the Liquid-Liquid Critical Point Hypothesis in Supercooled Water

   Författare :Alexander Späh; Anders Nilsson; Martin Meedom Nielsen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water; supercooled water; x-ray scattering; free electron x-ray laser; liquid-liquid phase transition; liquid-liquid critical point; x-ray speckle visibility spectroscopy; kemisk fysik; Chemical Physics;

   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

3. 2. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems

   Författare :Fredrik Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle Image Velocimetry PIV ; single-phase; Laser Doppler Anemometry LDA ; mixing; liquid-Liquid; immiscible; stirred tank; Rushton turbine; Computational Fluid Dynamics CFD ; macro-instability; frequency analysis; refraction index matched;

   Sammanfattning : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. LÄS MER

7. 5. Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on bis-triazine-bipyrididine (BTBP)-class Ligands

   Författare :Elin Löfström Engdahl; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Used nuclear fuel; Density; Solvent; Extraction vs. time; BTBP; GANEX; Liquid-Liquid Extraction; Interfacial tension; Diluent;

   Sammanfattning : Used nuclear fuel taken directly from a reactor is radiotoxic for mankind and its environment for a long time. One of the major contributions to the long time radiotoxicity is the presence of a group of elements called the actinides. LÄS MER
