  1. 11. Improving the Performance of Gas Sensor Systems with Advanced Data Evaluation, Operation, and Calibration Methods

    Författare :Manuel Bastuck; Andreas Schütze; Mike Andersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In order to facilitate the widespread use of gas sensors, some challenges must still be overcome. Many of those are related to the reliable quantification of ultra-low concentrations of specific compounds in a background of other gases. LÄS MER

  2. 12. Molten Salt Electrolytes for Calcium Batteries

    Författare :Johanna Timhagen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Batteries; Metal anodes; Molten salt electrolytes; Calcium;

    Sammanfattning : Batteries are in higher demand than ever before as well as increased requirements in terms of energy and power density. The desire for higher energy density has meant that electrolytes are pushed above their electrochemical stability limits and hence they decompose, but typically this is under control and a new beneficial phase is created at the electrode surface; the solid electrolyte interphase (SEI).

  3. 13. Ions interacting with macromolecules : NMR studies in solution

    Författare :Yuan Fang; Istvan Furo; Monika Schönhoff; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electrophoretic NMR; diffusion NMR; specific ion effects; Hofmeister; ion binding; Kemi; Chemistry;

    Sammanfattning : Specific ion effects, identified for more than hundred years, play an important role in a wide range of phenomena and applications. Several mechanisms such as direct ion interaction with molecules have been suggested to explain these effects, but quantitative experimental evidence remains scarce. LÄS MER

  4. 14. Fluorine-Free Ionic Liquids and Electrolytes : From Synthesis to Energy Storage Applications

    Författare :Mukhtiar Ahmed; Faiz Ullah Shah; Patrik Johansson; Alexander Shaplov; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic Liquids; Electrolytes; Sustainability; Lithium ion batteries; Flourine-Free; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Since their introduction by Sony in 1990, lithium-ion batteries (LIBs) have acquired a sizable market share. They have the best energy densities, a high open circuit voltage, a low self-discharge rate, no memory effect, and a slow loss of charge when not in use. LÄS MER

  5. 15. Experimental studies on endotoxin infusion in human : evaluation of pharmacological immunomodulation by adenosine and nicotinamide

    Författare :Anne Soop; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Septicaemia and the systemic inflammatory response syndrome (SIRS), is a major cause of mortality among patients in the intensive care units. Inflammation and thrombosis involve multicellular phenomena with activation of leukocytes, platelets and endothelial cells resulting in synthesis and release of various mediators e.g. LÄS MER
