a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
Novel N, S co-doped graphene (NSG) was prepared by annealing graphene oxide with thiourea as the single N and S precursor. The NSG electrodes, as efficient metal-free electrocatalysts, show a direct four-electron reaction pathway, high onset potential, high current density and high stability for the oxygen reduction reaction.
Standard myoelectric control systems use carefully placed bipolar electrode pairs to provide independent myoelectric signals (MESs) for prosthesis control. Because myoelectric pattern recognition systems do not require isolated MESs, the two electrode poles used for each MES channel may be placed longitudinally along individual muscles or transversely across multiple muscles. In addition, each ...
A new design, flat-bottom combination pH electrode was evaluated for utility in determining the pH of prepared agar media by surface contact of the electrode with the agar media.
the combination of graphene (gr) and nickel oxide nanoparticles (nio nps) yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry (cv) studies, in the presence of ep, nio/gr composite modified electrode shows a significantly higher current response for ep oxidation. based on differential pulse voltamm...
OBJECTIVES The objective of this study was to determine whether the threshold for successful cardiac pacing is affected by electrode impedance and whether this procedure can be successfully carried out through low impedance electrodes that are also suitable for defibrillation. BACKGROUND Reintroduced in the early 1980s, external cardiac pacing utilizes large externally placed electrodes with ...
