  2. 1. Liquid Sensing : Development and Characterisation of an Electronic Tongue Based on Electrochemical Methods

    Author : Susanne Holmin; Elena Dominguez; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : A new sensor technology for liquid sensing is reported, i.e. the electronic tongue based on electrochemical methods. Such a system involves the combination of non-selective sensors (metal electrodes) and a signal processing part. READ MORE

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

    Author : Alexander Späh; Anders Nilsson; Martin Meedom Nielsen; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

    Abstract : Bioanalytical chemistry is a challenging field, often involving complex samples, such as blood, plasma, serum or urine. In many applications, sample cleanup is the most demanding and time-consuming step. READ MORE

  7. 5. Analytical Supercritical Fluid Extraction of Lipid Containing Samples

    Author : Mattias Järemo; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SFC; extraction cell; liquid samples; fat retainers; lipids; SFE; carbon dioxide; Analytical chemistry; Analytisk kemi;

    Abstract : Traditionally, sample work-up has been associated with different kinds of liquid extraction techniques involving a large consumption of hazardous solvents. There are today regulations that aims at replacement of dangerous chemicals which has created a need for new extraction techniques. READ MORE
