Electronic structure of polyacetylene with bonded oxygen
(1992-09-01)
In this work we have studied the electronic structure of finite polyacetylene chains with structural oxygen-bonding models following data from 13C-NMR experiments. We have used a combination of Austin Method One and ...
Spin effects in oxygen electrocatalysis: a discussion
(Elsevier Science, 2013-04)
The reduction of molecular oxygen in triplet and singlet spin states at metal electrodes is analyzed in the framework of quantum mechanical theory of charge transfer. Both outer- and inner-sphere mechanism is considered. ...
Development of an electrochemical sensor for determination of dissolved oxygen by nickel-salen polymeric film modified electrode
(Elsevier B.V. Sa, 2012-12-01)
An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N'-ethylene bis(salicylideneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen ...
Structural studies in lead germanate glasses: EXAFS and vibrational spectroscopy
(1993-12-01)
The Raman, IR absorption and EXAFS spectra at the Ge K-edge and Pb LIII-edge of eight lead germanate glasses, with general formula xPbO(1-x)GeO2 with x = 0.20, 0.25, 0.33, 0.40, 0.50, 0.53, 0.56 and 0.60, have been measured. ...

Development of Nanostructured Electrochemical Sensor Based on Polymer Film Nickel-Salen for Determination of Dissolved Oxygen
(Elsevier B.V., 2011-01-01)
An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N '-ethylenebis(salicydeneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen ...
