Indolizine has been synthesised on the small scale with enhanced yield using a novel Flash Vacuum Pyrolysis method. Electrooxidation of indolizine results in the formation of a redox-active film on the electrode surface. Excellent agreement is found between calculated and experimental indolizine oxidation potentials; a combination of fluorescence and electrochemical studies are consistent with ...

The H2 electrode is commonly assumed to be a half-cell, 2 H + 2e == H2, and explained by the Nernst equation. We cannot assume that the H is easily reduced to H2 in an H2 saturated solution, and H2 becoming oxidized to H in a strongly acid solution against the equilibrium principle. How can the H2 gas is involved from a basic solution where there is practically no H ions? Another equilibrium ha...

INTRODUCTION Pulsed amperometry is a powerful detection method for carbohydrates that requires no sample derivatization. Pulsed amperometric detection (PAD) is particularly useful in combination with high-performance anion-exchange chromatography (HPAE). For a full description of HPAEPAD, refer to Dionex Technical Note 20. For an introduction to amperometry refer to Conductivity and Amperometry...

An electrode in a lithium-ion battery may undergo inelastic processes of two types: flow and reaction. Flow changes the shape of the electrode, preserves its composition and volume, and is driven by the deviatoric stress — a process similar to the plastic flow of a metal. By contrast, reaction changes the composition and volume of the electrode, and is driven by a combination of the mean stress...

Solid electrolytes based on oxygen ion conductors find extensive applications as devices for oxygen sensor, oxygen pumps, solid oxide fuel cells and electrocatalytic reactors. When using ceramic ionic conductors for applications, frequent attempts are made to improve the performance of the electrochemical system by apply'rig mixed conductors as thin top layers instead of the conventional ir~ert...

Objective To evaluate incidence of interscalar excursions between round window (RW) and cochleostomy approaches for cochlear implant (CI) insertion. Methods This was a retrospective case-comparison. Flat-panel CT (FPCT) scans for 8 CI users with Med-El standard length electrode arrays were collected. Surgical technique was identified by a combination of operative notes and FPCT imaging. Four ...

Supercapacitors (SCs) have garnered considerable attention as an appealing power source for forthcoming smart energy era. An ultimate challenge facing the SCs is the acquisition of higher energy density without impairing their other electrochemical properties. Herein, we demonstrate a new class of polyacrylonitrile (PAN)/multi-walled carbon tube (MWNT) heteromat-mediated ultrahigh capacitance e...
