Ion transport in polymer electrolytes
(University of St Andrews, 1993) - ThesisThe ion-polymer and ion-ion interactions in polymer electrolytes based on high molecular weight, amorphous methoxy-linked PEO (PMEO) and lithium salts have been investigated by conductivity measurement, magic-angle spinning ... -
Conductivity and nuclear magnetic resonance studies on polymer electrolytes based on poly(ethylene oxide)
(University of St Andrews, 1988) - ThesisThe thesis details studies relating to polymer electrolytes; the solid ionic conductors farmed by the dissolution of salts in suitable high molecular weight polymers. An outline of polymer electrolyte study is presented ... -
Studies of mass transport in some poly(ethyleneoxide)-based polymer electrolytes
(University of St Andrews, 1991) - ThesisThe work in this thesis relates to the transport of salt species in polymer electrolytes, which are solid ionic conductors in which mass transport is similar to that in liquids, rather than in ion-conducting glasses. A ... -
Multivalent ions in polymer electrolytes
(University of St Andrews, 1993) - ThesisThe electrochemical, thermal and structural properties of polyethylene oxide (PEO) based polymer electrolytes containing multivalent ions were investigated. The phase diagram for the PEO:Ca(CF₃SO₃)₂ system was determined ... -
Investigations of some energy transfer processes associated with acetylacetonate complexes of the lanthanoid and groups I and II metal ions
(University of St Andrews, 1979) - ThesisIntermolecular energy transfer occurs between Tb(aa)₃.3H₂0 and Ln(aa)₃.3H₂O complexes (Ln = Pr, Nd, Sm, Eu, Dy, Ho or Er; aa = acetylacetonate) in n-butanol solution at 293K. Measurement of the decay time of the Tb³⁺ ...
