The competition between the glyme molecules and the salt anions for the coordination to the lithium cations is quantified by comprehensive aggregate analyses. Lithium-glyme solvates are dominant in the lithium bis(trifluoromethylsulfonyl)imide systems and much less so in systems based on the other two salts. The aggregation studies also emphasize the existence of complex coordination patterns between the different species (cations, anions, glyme molecules) present in the studied fluid media. The analysis of such complex behavior is extended to the conformational landscape of the anions and glyme molecules and to the dynamics (solvate diffusion) of the bis(trifluoromethylsulfonyl)imide plus triglyme system.]]> Wed 11 Apr 2018 16:08:15 AEST ]]> Micelle structure of novel diblock polyethers in water and two protic ionic liquids (EAN and PAN) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:20327 109EO54, EGE113EO115, EGE104EO178, and GPrE98EO260) have been investigated between 10 and 100 °C, showing how aggregate structure changes with increasing the EO block length, by changing the insoluble block from EGE to the more bulky, hydrophobic GPrE block, and with temperature. EO solubility mainly depends on the hydrogen bond network density, and decreases in the order H₂O, EAN, and then PAN. The solubility of the EGE and GPrE blocks decreases in the order PAN, EAN then water because the large apolar domain of PAN increase the solubility of the solvophobic blocks more effectively than the smaller apolar domains in EAN, and water, which is entirely hydrophilic; GPrE is less soluble than EGE because its larger size hinders solubilization in the IL apolar domains. Large disk-shaped structures were present for EGE109EO54 in all three solvents because short EO chains favor flat structures, while GPrE98EO260 formed spherical structures because long EO chains lead to curved aggregates. The aggregate structures of EGE113EO115 and EGE104EO178, which have intermediate EO chain lengths, varied depending on the solvent and the temperature. Solubilities also explain trends in critical micelle concentrations (cmc) and temperatures (cmt).]]> Wed 11 Apr 2018 12:26:49 AEST ]]> Nanostructure of [Li (G4)] TFSI and [Li (G4)] NO₃ solvate ionic liquids at HOPG and Au (111) electrode interfaces as a function of potential https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26887 Wed 11 Apr 2018 11:23:56 AEST ]]> Effect of variation in anion type and glyme length on the nanostructure of the solvate ionic liquid/graphite interface as a function of potential https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34122 Tue 12 Feb 2019 13:11:58 AEDT ]]> Li⁺ local structure in li-tetraglyme solvate ionic liquid revealed by neutron total scattering experiments with the ⁶/⁷Li Isotopic Substitution Technique (letter) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25095 Sat 24 Mar 2018 07:15:03 AEDT ]]> Adsorption of polyether block copolymers at silica-water and silica-ethylammonium nitrate interfaces https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24931 Sat 24 Mar 2018 07:14:20 AEDT ]]>
