  1. 16. Fluorine-Free Phosphorus-Based Ionic Materials and Electrolytes

    Författare :Yanqi Xu; Faiz Ullah Shah; Patrik Johansson; Jonas Örtegren; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluorine-free electrolytes; Physiochemical properties; Nuclear magnetic resonance; Ion interactions; Single crystal structures; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Due to the successful commercialization of lithium-ion batteries (LIBs), there is a growing interest in developing new battery materials with beneficial electrochemical properties. However, the uneven distribution of lithium resources and the low abundance of lithium in the earth crust are the main obstacles for further development and large-scale production of LIBs. LÄS MER

  3. 17. Ab initio modeling of xanthate adsorption on ZnS surfaces

    Författare :Pär Hellström; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Teknisk-vetenskapliga beräkningar;

    Sammanfattning : Modeling surface adsorption requires systems of hundreds of atoms. To model such systems at an ab initio level successfully, we need to avoid traditional quantum chemical methods. LÄS MER

  5. 19. Tight-Binding Modelling of Deep Eutectic Solvent-Based Lithium Battery Electrolytes

    Författare :Mirna Alhanash; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; xTB; tight-binding; deep eutectic solvent; electrolyte.;

    Sammanfattning : In recent years, there has been a growing interest in utilizing liquid electrolytes such as deep eutectic solvents (DES) as electrolytes for lithium batteries, owing to their numerous advantageous properties, including ease of preparation, tunability, wide electrochemical stability windows, and low vapor pressures. However, an aspect that remains poorly understood is the intricate relationship between the local structural symmetry, entropy, and the macroscopic properties of DES electrolytes. LÄS MER

  7. 20. Laser-based diagnostics for investigating soot formation in combustion processes

    Författare :MANU Mannazhi; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soot formation; Laser diagnostics; Combustion; Laser-induced Incandescence; Fysicumarkivet A2022:Mannazhi;

    Sammanfattning : In this work, laser-based diagnostic techniques were developed and applied to investigate soot formation in small-scale laboratory burners as well as in practical combustion devices. Quantitative 2D laser-induced incandescence (LII) measurements often use a cylindrical lens to shape the beam and illuminate the planar region of interest. LÄS MER
