Crystal Structure, Spin Polarization, Solid-State Electrochemistry, and High n-Type Carrier Mobility of a Paramagnetic Semiconductor: Vanadyl Tetrakis(thiadiazole)porphyrazine

open access: closedInorganic Chemistry, 2011
We report the synthesis, crystal structure, and magnetic, electrochemical, and carrier-transport properties of vanadyl tetrakis(thiadiazole)porphyrazine (abbreviated as VOTTDPz) with S = ½. X-ray crystal analysis reveals two polymorphs, the α and β forms; the former consists of a 1D regular π stacking, while the latter forms a 2D π network.

A Study of Corrosion Electrochemistry of Steel in Chloride Contaminated Concrete Using a Rapid Scan Polarization Technique

open access: closedCORROSION 1987, 1987
Abstract Corrosion of steel in portland cement concrete has been found to be very damaging and costly to many countries in the world. It is possible to control this corrosion damage in several ways and one of these is the use of inhibitors.

The Critical Role of Atomic‐Scale Polarization in Transition Metal Oxides on Vanadium‐Redox Electrochemistry

open access: closedAdvanced Materials
AbstractTransition metal oxide electrocatalysts (TMOEs) are poised to revive grid‐scale all‐vanadium redox flow batteries (VRFBs) due to their low‐cost and unique electronic properties, while often inescapably harboring surface vacancies. The role of local vacancy‐induced physicochemical properties on vanadium‐redox electrochemistry (VRE), encompassing

Correlation of surface concentration polarization with the surface electrochemistry of a permselective Membrane: An ex situ electrical impedance spectroscopy study

open access: closedJournal of the Taiwan Institute of Chemical Engineers, 2017
Abstract Surface concentration polarization induces fouling processes accompanied by changes in the resistance of a semipermeable membrane, but the connection between these two phenomena has not yet been evaluated. Here, we propose to connect them by introducing the concept of pH equivalent (pHeq), which is used to describe the electrical properties ...

Structure and Electrochemistry of LiV3O8 Thin Film Electrode: Effect of Diffusion Rate and Concentration on Cell Polarization

open access: closedECS Meeting Abstracts, 2019
Electrochemistry of lithium trivanadate (LiV3O8, LVO) has been extensively studied due to its large capacity and high rate capability. The material undergoes both insertion/extraction and phase transform reactions during discharge and charge in a Li-ion battery. However, the rate limiting factors of the material are unclear over the cycling window of

Dependence of Quinone Electrochemistry on Solvent Polarity and pH

Journal of The Electrochemical Society, 2022
We studied the polarographic reduction of quinones in aqueous/organic mixtures with dielectric constants ( ε ) from 78.4 down to 47. Added organic co-solvents were either protic or aprotic. The increase in polarographic half-wave potential, E 1/2

Alleviating the common confusion caused by polarity in electrochemistry

Journal of Chemical Education, 1989
The issue of polarity encountered in electrochemistry and relevant to a variety of electrochemical concepts often confuses students and is an unnecessary deterrent to the study of electrochemistry.
