Coupled channel study of kaonic 12C

A coupled channel formalism is used to study the role of the Λ(1405) for kaonic ¹²C in a non-static way. Medium corrections are calculated in a microscopic fashion, closely related to a Brueckner type of “independent pair approximation”. Nucleon and kaon binding effects (the latter in a rudimentary self-consistent way) and the Pauli blocking effect are examined and some of the widely used approximations (Fermi gas and local density, closure approximation) are put to trial. Fair agreement with experiment can be obtained without a free parameter, but it is shown to depend sensitively on the input elementary (sub-threshold) scattering amplitude.     

The electrochemistry of arylated anthraquinones in room temperature ionic liquids

Arylated anthraquinone derivatives of different sizes and different π‐basicities have been prepared, and the electrochemical behaviour of these substances has been studied on screen printed graphite electrodes in the three room temperature ionic liquids (RTILs), 1‐butyl‐3‐methylimidazolium hexafluorophosphate ([C₄MIM][PF₆]), 1‐hexyl‐3‐methylimidazolium hexafluorophosphate ([C₆MIM][PF₆]) and 1‐octyl‐3‐methylimidazolium hexafluorophosphate ([C₈MIM][PF₆]). Half redox potentials for the first and second one electron reduction waves were identified, and the diffusion coefficient values were estimated from cyclic voltammetry measurements. The influence of the nature of the RTIL and of the substitution pattern of the anthraquinone on the solvodynamic radii were studied. A correlation of the reductive potentials with the corresponding Hammett constants of the substituents was tested. Copyright © 2013 John Wiley & Sons, Ltd.
