TL;DR: In this paper, the free-potential measurements of the open circuit potential measurements (freepotential) enabled the determination of the reactions responsible for the degradation of the materials, such as selective oxidation of Si and molybdenum.

TL;DR: In this article, a computer-based method is presented for a quantitative description of the kinetics in the latter case, based on the solution of differential equations using the finite difference technique.

TL;DR: In this article, the isotope effect of 2.4.6-trideuterostyrol is determined at different temperatures and at different monomer concentrations at different solvents.
Abstract: Kinetische Untersuchungen zur thermischen Polymerisation in verschiedenen Losungsmitteln und bei verschiedenen Temperaturen werden beschrieben. Der Isotopeneffekt beim 2.4.6-Trideuterostyrol wird bei verschiedenen Temperaturen und Monomerkonzentrationen bestimmt. Die erhaltenen Ergebnisse stehen mit den Vorstellungen MAYOS uber den Startschritt der thermischen Polymerisation in Einklang.
Kinetic investigations for thermal polymerization in different solvents and at different temperatures are described. The isotope effect of 2.4.6-trideuterostyrol is determinated at different temperatures and at different monomer concentrations. The results agree with the ideas expressed by MAYO about the initial step of thermal polymerisation.

TL;DR: In this article, the electrochemical redox behavior of alkyl bridged polythiophene derivatives poly(1,6-bis(3-thienyl-)hexane) and poly( 1,12-bis (3)-dodecane was investigated by cyclic voltammetry and compared to poly((3-hexyl)- thiophene), poly(3)-hexyl-)-thiophenes, and poly(( 3-dodeecyl-)thiopenes, respectively).

TL;DR: In this paper, the Fe(II)-ethylenediaminetetraacetic acid (EDTA)-NO complex formed by interaction of gaseous nitrous oxide (ca. 200 ppm) and Fe(2)-EDTA in aqueous solution was found to be convert3ed electrochemically on platinum electrodes at potentials below ca. {minus}0.6 V{sub SCE, indicating the cathodic reduction of NO.
Abstract: The Fe(II)-ethylenediaminetetraacetic acid (EDTA)-NO complex formed by interaction of gaseous nitrous oxide (ca. 200 ppm) and Fe(II)-EDTA in aqueous solution was found to be convert3ed electrochemically on platinum electrodes at potentials below ca. {minus}0.6 V{sub SCE}, indicating the cathodic reduction of NO. In addition to the previous studies by which the indirect conversion of NO with dithionite as a redox mediator was confirmed, the present results should elucidate the possibility of the direct electrochemical conversion of NO in mediator-free solutions. To clearly separate this process from other reactions in the system, the electrochemical behavior of Fe(II)-EDTA and Fe(III)-EDTA was studied over a wide potential range at different pH values. Five electrode reactions could be identified, which include the oxidation/reduction of Fe{sup 2+}/Fe{sup 3+} in the EDTA complex, the reduction of EDTA, the reduction of protons, the cathodic deposition of iron, and the anodic decomposition of EDTA. The electrochemical deposition of iron from Fe(II)-EDTA at potentials E < {minus}1.0 V{sub SCE} was confirmed by electrochemical quartz crystal microbalance measurements and energy-dispersive x-ray analysis.
