In the present study, solid oxide cells (SOCs) were operated in electricity generation (solid fuel cell, SOFC) mode and hydrogen production electrolysis SOEC) mode. The electrodes fabricated with nickel-gadolinia doped ceria (Ni-GDC) nickel-yttria stabilized zirconia (Ni-YSZ) composites investigated. correlations between changes microstructure degradation of electrochemical performance are disc...

This paper investigates the role of electrode– dielectric interactions, and barrier materials on leakage current, breakdown voltage, yield and reliability of thinfilm (Ba,Sr)TiO3 capacitors on silicon and glass substrates. The first part of the paper investigates the electrode–dielectric interactions with sputtered Cu and Ni electrodes to identify the mechanisms that lead to high leakage curren...

The structure and electrical conductivity of anode play a significant role in the power generation of microbial fuel cells (MFCs). In this study, we developed a three-dimensional (3D) reduced graphene oxide-nickel (denoted as rGO-Ni) foam as an anode for MFC through controlled deposition of rGO sheets onto the nickel foam substrate. The loading amount of rGO sheets and electrode surface area ca...

Quantum cross (QC) devices which consist of two Ni thin films deposited on polyethylene naphthalate (PEN) substrates with their edges crossing have been fabricated and its current-voltage characteristics have been investigated. The cross-sectional area between the two Ni electrodes, which was made without the use of electron-beam or optical lithography, is as small as 17 nm x 17 nm. We have suc...

Electrical discharges in liquids are considered an efficient and ecological technique of nanoparticle synthesis via controlled erosion electrodes. Herein, we use spark between Co–Co, Ni–Ni, Co–Ni, or Ni–Co electrodes immersed distilled water to synthesize Co and/or Ni nanoparticles, as well their oxides. When mixed used (Co–Ni Ni–Co), both nanoparticles produced, the major species is dictated b...

Ternary Pt-Ru-Ni deposits on glassy carbon substrates, Pt-Ru(Ni)/GC, have been formed by initial electrodeposition of Ni layers onto glassy carbon electrodes, followed by their partial exchange for Pt and Ru, upon their immersion into equimolar solutions containing complex ions of the precious metals. The overall morphology and composition of the deposits has been studied by SEM microscopy and ...

A novel fabrication method using electroless and electrodeposited Ni/Ag/GDC for SOFC anodes is presented. First a porous Ce0.9Gd0.1O2 x (GDC) scaffold was deposited on a YSZ electrolyte by screen printing and sintering. The scaffold was then metallized with silver using Tollens' reaction, followed by electrodeposition of nickel from a Watt's bath. The electrodes (Ni/Ag/GDC) were tested in both ...

• The kinetics of CH4 steam reforming and partial oxidation are determined by the oxidation rate of CHx adsorbed species • The modification of the Ni/YSZ and Ni/GDC with Au and/or Au-Mo results in differentiated structures of atomically dispersed Au and/or Au-Mo at the surface and the bulk of the Ni particles. • At lean S/C NiAu/YSZ selectively oxidizes electrochemically the catalytically produ...

In situ electropolymerization as a facile synthetic procedure has been used to obtain highly active compositesof ionic liquid functionalized graphene oxide(FGO)and poly ortho aminophenol (POAP). Surface and electrochemical analysis have been used for characterisation of FGO-POAP composite film. Nickel was accumulated by complex formation between Ni (II) in solution and amines sites in the polym...
