Potentiostatic study of ferrous–ferric kinetics at bright gold and platinum electrodes

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...

High resolution mapping of oxygen reduction reaction kinetics at polycrystalline platinum electrodes.

The scanning droplet-based technique, scanning electrochemical cell microscopy (SECCM), combined with electron backscatter diffraction (EBSD), is demonstrated as a powerful approach for visualizing surface structure effects on the rate of the oxygen reduction reaction (ORR) at polycrystalline platinum electrodes. Elucidating the effect of electrode structure on the ORR is of major interest in c...

Study of HMS Modified ZrO2 Supported Platinum Catalysts for Toluene Removal: Catalytic Combustion and Kinetics Study

Reaction behaviors and kinetics of catalytic oxidation of toluene with different feed flows over Pt/Zr(x)-HMS catalysts with Si/Zr ratio equal to 5, 10, 20 and 35 were investigated over a wide temperature range (200 – 500 oC). Results show that Pt/Zr(x)-HMS performs more easily toluene oxidation. The kinetic data were fitted by the Power-law and Mars–van Krevelen kinetic models. The fitting res...

The Apparent Oxidation-Reduction Potentials of Bright Platinum Electrodes in Synthetic Media Cultures of Bacteria.

Dissociation kinetics at polyacrylic latex-coated electrodes

Polystyrene/poly(acrylic acid) latex particles 0.26 μm in diameter, which were synthesized by emulsion copolymerization of styrene and acrylic acid, were immobilized on the platinum electrode in a uniform film. The film did not block the diffusion current of a ferrocene derivative in the solution. The voltammograms showed the reduction of hydrogen ion, which was supplied not only from the solut...
