In this contribution, a mathematical model allowing for the prediction of AC surface arc propagation on polluted insulators under non-uniform electric field is proposed. The approach based experimental concept Claverie and Porcheron. proposed model, which makes it possible to reproduce discharge, includes condition arrest propagating discharge. at tip discharge key parameter governing its rando...

Contemporary cochlear implants with multiple electrode stimulation can produce good speech perception but poor music perception. Hindered by the lack of a gold standard to quantify electric pitch, relatively little is known about the nature and extent of the electric pitch abnormalities and their impact on cochlear implant performance. Here we overcame this obstacle by comparing acoustic and el...

In this work, a synthesis of cubic-like CoMn2O4 uniform nanostructures with KOH-NaOH involved in the hydrothermal method has been reported. The crystal structure phase purity, functional groups, and morphology have investigated by X?ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-reso­lution transmission (HR-TEM) analyses. electrochemical behaviour electroactiv...

In this article electrochemical determination of captopril at the surface of the platinum coated nanoporous gold film (PtNPGF) electrode is reported using the cyclic voltammetry and amperometry. For the preparation of PtNPGF, the surface of NPGF electrode was covered with Cu layer using underpotential electrochemical deposition (UPD).Afterward, the copper layer is replaced with platinum ions vi...

This study investigates the technical feasibility of retro-filling a C3F7CN/CO2 gas mixture for existing SF6-insulated accelerators. Negative DC breakdown characteristics 20% C3F7CN / 80% CO2 and SF6 varying pressure, gap distance field uniformity are analyzed experimentally using four distinctly different electrode configurations. The shows higher strength than configurations with high uniform...

T This paper reports the mixing performance of an AC electroosmotic micromixer based on the three-dimensional extensional flow generated by a face-to-face, asymmetric pair of planar electrodes. This work represents the first successful use of such an asymmetric electrode pair in an AC electroosmotic micromixer. Due to the highly 3dimentional flow pattern generated by the face-to-face electrode ...

Cu electrodeposition was performed on a cylindrical AZ80 substrate with a U-shaped surface. A uniform deposition of Cu was achieved on an AZ80 electrode via galvanostatic etching, followed by Cu electrodeposition in an eco-friendly alkaline Cu plating bath. Improper wetting and lower rotational speeds of the AZ80 electrode resulted in an uneven Cu deposition at the inner upper site of the U-sha...
