In this research, the radiation-heterogeneous processes of water decomposition on surface zirconium dioxide nanoparticles (n-ZrO2) were studied. The kinetics buildup molecular hydrogen during radiolytic was also examined. production H2 and H2O2 through radiolysis investigated to develop a computational model disclose kinetic behavior radiolysis. enthalpy ZrO2 studied at temperature range T=1200...

Pd-based electro-catalysts are a key component to improve the methanol oxidation reaction (MOR) kinetics from alcohol fuel cells. However, performance of such catalysts is degraded over time. To understand microstructural/atomic scale chemical changes responsible for an effect, scanning (transmission) electron microscopy measurements and atom probe tomography were performed after accelerated de...

The electro-oxidation of formic acid catalyzed by Fe20Pt80 nanoparticles was studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) where the particles were deposited onto a gold electrode surface by the Langmuir-Blodgett (LB) technique at varied film thickness/coverage. It was found that the particle assembly thickness strongly affected the electrocatalytic activit...

Ibuprofen (IBU), a nonsteroidal anti-inflammatory drug, is one of the most widely used and frequently detected pharmaceuticals personal care products in water bodies. This study examined IBU degradation aquatic solutions via ferric ion activated peroxydisulfate (PDS) coupled with electro-oxidation (EC/Fe3+/PDS). The mechanisms involved three synergistic reactions EC/Fe3+/PDS system, including: ...

among the most common types of problematic soils, are probably the expansive ones. one of the modern methods of strengthening and improving the soil in place is the use of electro-osmotic improving treatment. this paper presents the design of an apparatus suitable for electro-osmotic treatment. a soil sample of a high expansive potential was compacted and the effect of electro-osmotic treatment...

This paper presents a hierarchical modeling approach for Solid-Oxide Fuel Cells from elementary kinetics to stacks. On a fundamental level, we have developed an analytical model for the evaluation of volume specific three-phase boundary length (vLtpb) in composite electrodes and electrochemical kinetics expressions to account for coverage dependent activation energies of various surface adsorbe...

In order to analyze the DNA amplification numerically with integration of the DNA kinetics, three-dimensional simulations, including flow and thermal fields, and one-dimensional polymerase chain reaction (PCR) kinetics are presented. The simulated results are compared with experimental data that have been applied to the operation of a continuous-flow PCR device. Microchannels fabricated by Micr...
