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

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

    Abstract : 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. READ MORE

  7. 5. New Strategies for Preparing Polymers with Hierarchical Architectures

    Author : Natacha Ndizeye; Ian A. Nicholls; Alessandra Maria Bossi; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Liquid crystalline media; molecularly imprinted polymers; non-ionic deep eutectic solvents; quartz crystal microbalance; Organic Chemistry; Organisk kemi;

    Abstract : The objective of this thesis was to explore novel approaches for controlling morphologies and molecular recognition behaviour of polymers and to use these strategies in conjunction with the molecular imprinting technique in order to either enhance polymer performance in quartz crystal microbalance (QCM) sensor applications, or as an alternative to conventional solvents of polymerization. In Papers I and II, the use of liquid crystalline media in the synthesis of molecularly imprinted polymers was demonstrated. READ MORE
