Application of Asymmetric Marcus-Hush Theory to Voltammetry in Room-Temperature Ionic Liquids

Asymmetric MarcusHush (AMH) theory is applied for the first time in ionic solvents to model the voltammetric reduction of oxygen in 1-butyl-1-methylpyrrolidinium bis-(trifluoromethylsulfonyl)-imide and of 2-nitrotoluene (2-NT), nitrocyclopentane (NCP), and 1-nitro-butane (BuN) in trihexyltetradecylphosphonium tris(pentafluoroethyl)trifluorophosphate on a gold microdisc electrode. An asymmetry parameter, gamma, was estimated for all systems as -0.4 for the reduction of oxygen and -0.05, 0.25, and 0 +/- 0.05 for the reductions of 2-NT, NCP, and BuN, respectively, which suggests equal force constants of reactants and products in the case of 2-NT and BuN and unequal force constants for oxygen and NCP where the force constants of the oxidized species are greater than the reduced species in the case of oxygen and less than the reduced species in the case of NCP. Previously measured values for a, the Butler-Volmer transfer coefficient, reflect this in each case. Where appreciable asymmetry occurs, AMH theory was seen to parametrize the experimental data better than either Butler-Volmer or symmetric Marcus-Hush theory, allowing additionally the extraction of reorganization energy. This is the first study to provide key physical insights into electrochemical systems in room-temperature ionic liquids using AMH theory, allowing elucidation of the reorganization energies and the relative force constants of the reactants and products in each reaction.

Gallic war songs (II): Marcus Cicero, Quintus Cicero, and Caesar’s invasion of Britain

This article assembles and examines the evidence for the poetic outputs of Marcus and Quintus Cicero related to Caesar’s invasion of Britain. Following the establishment of a relative chronology of the evidence for their work, it is argued that Quintus Cicero most likely produced a fabula praetexta (not an epic poem, as commonly assumed). His brother, in turn, wrote an epic, based on Quintus’ eye-witness reports. Careful analysis of the ancient discourse about this piece reveals insights in Cicero’s poetic workshop and the creation of ‘archival truth’ through narrativising historical events in epic poetry. Finally, a case is made for greater attention to financial affairs between Caesar and the Ciceros that happen to coincide with the drafting process of their respective literary works.
