In the present study, five modeling approaches of RA, MLP, MNN, GFF, and CANFIS were applied so as to estimate the radial overcut values in electrochemical drilling process. For these models, four input variables, namely electrolyte concentration, voltage, initial machining gap, and tool feed rate, were selected. The developed models were evaluated in terms of their prediction capability with m...

a new signal amplification strategy based on simultaneous application of gold nanoparticles (aunps) and horseradish peroxidase (hrp) was employed to improve the sensitivity of an electrochemical immunoassay for detection of human igg (higg), as a model antigenic protein. this immunoassay system was fabricated on magnetic carboxyl-functionalized multi-walled carbon nanotubes (cooh-mwcnt/fe3o4 na...

Oxidation behavior of AZ91D magnesium alloy with 3YSZ coating and aluminum interlayer was studied in air at 250 °C using electrochemical impedance spectroscopy EIS, scanning electron microscopy SEM, and X-ray diffraction XRD. The oxidation process was carried out in various duration times from 1 to 10 h. A three-electrode electrochemical cell was employed for all the EIS measurements. Also, to ...

An approach is developed for probing the thermodynamics and kinetics of irreversible electrochemical reactions on solid surfaces based on local frequency-voltage spectroscopy. For a model Li-ion conductor surface, two regimes for bias-controlled behavior are demonstrated and ascribed to the difference in the critical nucleus size. The electrostatic and electrochemical phenomena at the tip-surfa...

Title of Document: MODEL DEVELOPMENT FOR GADOLINIADOPED CERIA-BASED ANODES IN SOLID OXIDE FUEL CELLS Lei Wang, Doctor of Philosophy, 2014 Directed By: Professor Gregory S. Jackson, Department of Mechanical Engineering Intermediate temperature (500 700 °C) solid oxide fuel cells (IT-SOFCs) with gadolinia-doped ceria (GDC) electrolytes have significant commercial potential due to reduced material...
