  1. 21. Innovative Electrolytes for Safer Sodium-Ion Batteries

    Författare :Damien Monti; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Raman spectroscopy; safety; Sodium-ion batteries; ionic liquids; organic solvents; electrolytes; ionic conductivity; electrochemistry.; electrodes;

    Sammanfattning : The overconsumption of non-renewable/fossil fuels by vehicles and industry has resulted in dangerously high levels of CO2 in the atmosphere the last 40 years. The impact on the environment, climate and public health urge governments to find new technologies to ensure a sustainable development. LÄS MER

    Sammanfattning : In this thesis degradation of chlorinated solvents, e.g., tetrachloroethene (perchloroethylene [PCE]), has been examined, both natural occurring degradation and in situ remediation strategies. LÄS MER

  4. 23. Separation of Pharmaceuticals by Capillary Electrophoresis using Partial Filling and Multiple-injections

    Författare :Henrik Lodén; Curt Pettersson; Torbjörn Arvidsson; Ahmad Amini; Morgan Stefansson; Uppsala universitet; []
    Nyckelord :Capillary Coating; Chiral Separation; Enantiomers; Mass-spectrometric Detection; Method Validation; Multiple-injection Capillary Zone Electrophoresis; Non-aqueous Capillary Electrophoresis; Organic Solvents; Pharmaceutical Analysis; Quantitative Analysis;

    Sammanfattning : Different multiple-injection methodologies and the partial filling technique (PFT) have been utilized for separation of pharmaceuticals by capillary elec-trophoresis. In multiple-injection capillary zone electrophoresis (MICZE), the samples and all standards, used for construction of the calibration curve, are analyzed within a single run. LÄS MER
