Characterization of New Systems for the Catalytic Electroreduction of Oxygen by Electrochemistry anion for two Co catalysts. The catalysts are cobalt phthalocyanine (catalyst 1) and polyacrylonitrile + cobalt acetate (catalyst 2) adsorbed on carbon black and heat treated at several temperatures. A maximum for the catalytic activity was obtained for PcCo at 850 °C and for the PAN + Co catalyst at

EXAFS Studies of Film Coated Electrodes,d copper complexes of 2,9-dimethylphenanthroline embedded in Nafion films to study the change from four to five coordination which occurs on oxidation of Cu(I) to Cu(II). The increase in coordination number presumably occurs from the addition of a water ligand on rearrangement from tetrahedral to tr

J. Robinson On a theorem of functional analysis published in 1938, exactly 70 years ago, where the original Sobolev inequality was proved. This double event is a good case to gather experts for presenting the latest results on the study of Sobolev inequalities which play a fundamental role in analysis, the the
