In the one-screen semi-industrial apparatus the excess heat developed was carried off by a system of cooling pipes, the closed ends of which were embedded in the catalyst. Either air or water could be used as the cooling medium. In this oxidation of aliphatic hydrocarbons the author usually prefers to keep the temperature of the catalyst below 400° C. (usually 280° to 380° C.) hence, in an apparatus larger than that used in the laboratory, the temperature tends to rise, because of the greater distance to any radiating surface and the non-conducting character of the catalyst and its carrier, which is usually asbestos. 

The polarized single crystal specular reflectance and solution absorption spectra have been reported for 20 (M = Rh, Ir R = H) (44, 474). A high reflectivity at 19100 cm (e — 14000 1/mole cm) and 17600 cm (s 15000 1/mole cm) were reported for the rhodium and iridium complexes respectively. These reflectances account for the metallic luster of these complexes and are assigned to a -> L r transition. The final state is characterized as a Frenkel exciton consistent with the poorly conducting character of these complexes. 

Similar systems to those discussed above are found in Ref. [110] and Ref. [111]. In Ref. [Ill], Fe or Ru metal ions are co-ordinated to two bipy ligands, each one interposed between two EDOT units. Polymerization at the extreme EDOT residues occurs, the metal also acting as a bridge between two adjacent oligomeric chains. The shortness of the organic segments between adjacent metal complexes causes the redox conductivity character to largely predominate. A... 

It should also be stressed that the racemic salt obtained with dl-camphorsulfonate is not isostructural with its enantiopure counterpart [33]. Albeit a mixed-valence 2 1 salt was also obtained, crystallizing with solvent inclusion, giving rise to a one-dimensional electronic structure and semi-conducting character. Halogen bonding interactions with the EDT-TTFl2 molecules are still present with the shortest O- I distances above 2.81 A, which is 80% of the sum of the van der Waals radii. 

Until quite recently, most scientists believe that the Stokes-Einstein equation can be applied even in solid polymer system. That means, larger cations receive larger resistance because of larger size. However, it was clarified that the fast ion migration could be achieved by the use of not strong but moderate Ion-Dipole interaction. In near future, polymers with more excellent ion conductive characters will be designed. The control of interaction between carrier ions and polymer matrix is the key point for this purpose.
