Electrochemical sensors in the analysis and control of bioprocesses.

Abstract: The need for real-time, in-situ monitoring and control of the chemical composition of fermentation reactions has led to several novel approaches in the development of amperometric electrochemical sensors.

Apparatus for retaining slag during the discharge of molten metal from a tundish

Abstract: Apparatus for retaining slag in a tundish or a ladle or similar vessel containing molten metal such as used in the steel industry. A refractory nozzle member and a refractory retainer member are secured to the bottom of the vessel around the molten metal discharge orifice. A refractory plug member of a density between that of the molten metal and the slag is positioned laterally within the retainer member but free to move vertically during discharge of the molten metal from the vessel.

The Effect of Chromium Content (0 to 35%) in Fe-Cr Alloys on Corrosion Rates and Mechanisms in 1.0 N Sulfuric Acid

Abstract: The effect of chromium content (0 to 35 percent) in Fe-Cr alloys on their dissolution in 1.0 N sulfuric acid was investigated. Corrosion rates increase with increasing chromium content. Corrosion rates were determined by three electrochemical techniques (Tafel extrapolation, three-point, and polarization resistance methods) and were compared with the rates determined by weight-loss measurements. The cathodic hydrogen evolution reaction is independent of the chromium content; that is, the exchange current density (i0) and the Tafel slope (βc) are essentially constant with changes in chromium content. The anodic Tafel constant (βa) for alloy dissolution is also independent of the chromium content. The increase in corrosion rates observed with increasing chromium content is directly proportional to the change in the active direction of anodic open-circuit potential and, therefore, also the corrosion potential in this case. Some effects of this phenomenon on pitting and crevice corrosion in chloride ...
