Inhibition Efficiency of Goji Berry Extract Against the Corrosion of Carbon Steel SAE 1045

open access: yesOrbital: The Electronic Journal of Chemistry, 2021
Corrosion degrades the surface of metals. Therefore, extracts of natural products are tested as possible corrosion inhibitors, in order to delay or inhibit such processes.

Electrochemistry in media of exceptionally low polarity: Voltammetry with a fluorous solvent [PDF]

open access: yesJournal of Electroanalytical Chemistry, 2010
This work demonstrates the first cyclic voltammetry in a perfluorocarbon solvent without use of a cosolvent. The novel electrolyte tetrabutylammonium tetrakis[3,5-bis(perfluorohexyl)phenyl]borate (NBu(4)BArF(104); 80 mM) allows for voltammetry of ferrocene in perfluoro(methylcyclohexane) by lowering the specific resistance to Ω268 k cm at 20.8 °C ...

Investigation of effect of electrode polarity on electrochemistry and magnetohydrodynamics using tertiary current distribution in electroslag remelting process [PDF]

open access: yesJournal of Iron and Steel Research International, 2021
AbstractTransport phenomena including the electromagnetic, concentration of ions, flow, and thermal fields in the electroslag remelting (ESR) process made of slag, electrode, air, mold, and melt pool are computed considering tertiary current distribution. Nernst–Planck equations are solved in the bulk of slag, and faradaic reactions are regarded at the

Wireless magneto-ionics: voltage control of magnetism by bipolar electrochemistry

open access: yesNature Communications, 2023
Modulation of magnetic properties through voltage-driven ion motion and redox processes, i.e., magneto-ionics, is a unique approach to control magnetism with electric field for low-power memory and spintronic applications. So far, magneto-ionics has been

Unusual kinetic behavior in cathodic H2 evolution from KF.2HF melts at mild-steel and alloy electrodes [PDF]

open access: yesHemijska Industrija, 2004
Apart from its interest as a "model" process for kinetic studies of gas-evolving electrode reactions, the cathodic hydrogen evolution reaction (her) is involved in several processes that are of importance in applied electrochemistry, e.g., as the ...
