Employment of Electrochemical Sensors in Determination of Corrosion Rate In Situ in Formation Water Petroleum

Revista Cubana de Ingeniería, 2016
The electrochemical corrosion is a spontaneous process that causes deterioration or destruction of aninstallation or pipes, shortening therefore the useful life of the same ones.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Low-cost electrochemical impedance spectroscopy system for corrosion monitoring of metallic antiquities and works of art [PDF]

, 1999
Electrochemical impedance spectroscopy (EIS) is recognized to be a powerful and noninvasive technique to test the integrity of protective coatings on memorials, but commercial EIS systems are rather costly though versatile devices. This paper describes a

Some electrochemical aspects of the Becher process

, 1997
The Becher process is used to upgrade ilmenite (~60% TiO2) to synthetic rutile (92-95% TiO2). Reduced ilmenite (FeTiO2) is an intermediate mineral product and the industrial process whereby metallic iron is corroded from the TiO2 matrix (leaving ...

Laplace‐Pressure‐Stabilized Rutile Solid‐Solution Catalysts for Acidic Water Oxidation: Enabling DSA‐Inspired Compositions

Advanced Materials, EarlyView.
The miscibility of foreign elements in rutile‐type IrO2 and SnO2 is greatly enhanced under high Laplace pressure, where their crystal size is reduced to the nanoscale. This enhancement leads to the successful synthesis of DSA‐composition solid‐solution nanocatalysts with notable durability during the acidic OER in water electrolysis.
