Unlike water and conventional ionic liquids, [Li(G4)]TFSI cannot form hydrogen bonds with PEO. Thermal gravimetric analysis indicates that the solvation of PEO by [Li(G4)]TFSI is a consequence of PEO forming coordinate bonds with the lithium by displacing the anion, but without displacing the glyme molecule.]]> Wed 11 Apr 2018 10:55:18 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34122 Tue 12 Feb 2019 13:11:58 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34719 via stick-slip events. In contrast, friction at Au(111) for Li(G4) TFSI is significantly higher at positive potentials than at negative potentials, which is comparable to that at HOPG at the same potential. The similarity of boundary layer friction at negatively charged HOPG and Au(111) surfaces indicates that the boundary layer compositions are similar and rich in Li⁺ cations for both surfaces at negative potentials. However, at Au(111), the TFSI⁻ rich boundary layer is less lubricating than the Li⁺ rich boundary layer, which implies that anion reorientations rather than stick-slip events are the predominant energy dissipation pathways. This is confirmed by the boundary friction of Li(G4) NO₃ at Au(111), which shows similar friction to Li(G4) TFSI at negative potentials due to the same cation rich boundary layer composition, but even higher friction at positive potentials, due to higher energy dissipation in the NO₃⁻ rich boundary layer.]]> Tue 03 Sep 2019 18:26:08 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27760 Sat 24 Mar 2018 07:27:43 AEDT ]]>
