Towards Sacrificial Anode-Free Alkyne Electrocarboxylation
… alkyne electrocarboxylation routes rely on sacrificial metal anodes which inhibit their scalability and implementation in continuous flow systems. The aim of this research is to establish a scalable, sacrificial anode-free electrocarboxylation process. This work explores the sacrificial …

Investigation of New, Low-Voltage, Aluminum, Sacrificial Anode Chemistries
… on the performance of low voltage, aluminum, sacrificial anodes. We have developed an overview of elemental trends and a comparison with literature, in support of a larger program on predicting anode behavior. The broader impact of this work was to enhance the ability to control corrosion and …

Mechanical and cathodic protection aspects of multi-barrier tuff repository canister designs
… various corrosion modes were identified, and a sacrificial anode was designed to cathodically protect the waste package for a period of 10,000 years. The sacrificial anode is to be made of magnesium. Langelier and Larson's Indices were calculated and speciation calculations of J-13 water was …

High-temperature corrosion study of alloys in molten MgCl₂-KCl eutectic salt
… in the MgCl₂-KCl molten salt: 1) adding a sacrificial anode into the salt, and 2) coating a high-corrosion-resistance alloy. Mn, Zn, and Zr are chosen as the sacrificial anode materials to protect the alloys from further corrosion. The result showed that additions of inhibitor into the …

Preventing Stern Tube Corrosion through Shipboard Cathodic Protection
… Multiphysics, polarization experiments, and sacrificial anode wastage estimation. Lastly, nonintrusive load monitoring, with its diagnostic capabilities, provides an opportunity to advance the complicated field of study of corrosion protection. A nonintrusive load monitor (NILM) samples the …

Al-Ga Sacrificial Anodes: Understanding Performance via Simulation and Modification of Alloy Segregation
… conditions, and would be a good choice for a sacrificial anode to protect steel structures if it did not passivate. However, various elements can be added to aluminum to prevent this passivation. Currently, Al-Ga alloys are used commercially as sacrificial anodes but their performance is not …

Development of Anti-corrosive Polyester Powder Coatings
… with passivation effect, zinc powder with sacrificial anode effect, and two nanoclays with barrier effect were incorporated into the coatings to enhance the anti-corrosive performance. The anti-corrosive properties were evaluated by electrochemical techniques and neutral salt spray tests. …

Coupling of Oxidation-Reduction Reactions of Chromium, Iron and Manganese: Implications for the Fate and Mobility of Chromium in Aquatic Environments
… electrocoagulation (EC) with iron serving as the sacrificial anode to treat simulated drinking water solutions. Experiments have evaluated the effects of pH, dissolved oxygen, and common anions on Cr(VI) removal during batch EC treatment. In addition, the presence of humic acid (HA) inhibited the …

Limitations to Use Copper as an Antimicrobial Control of Legionella in Potable Water Plumbing Systems
… to be important controlling factors. The type of sacrificial anode rod material employed in water heaters was also identified as an underappreciated factor, which directly affects pH, evolution of hydrogen gas as a microbial nutrient, and release of metals (such as aluminum) that bind copper. …

Discrete sacrificial anodes and their use in service life extension of chloride contaminated reinforced concrete structures
… other potentially successful methods such as sacrificial anodes are rarely applied. Sacrificial anode cathodic protection (SACP) systems use metals that are higher than steel in the electrochemical series. These metals corrode preferentially to steel thereby supplying electrons to the cathodic …

Separation and Properties of La₂O₃ in Molten LiF-NaF-KF Salt
… the fluorine ions reacted with the tungsten anode to form tungsten fluoride. In the experiments, the production of tungsten fluoride could lead to increasing current in the cell, even overload. Moreover, theoretically, tungsten fluoride WF4 is soluble in the fluoride salt thus introducing new …

The Innovative Use of Electrocoagulation-Microwave Techniques for the Removal of Pollutants from Water
… generated in-situ by electrolytic oxidation of a sacrificial anode. In this technique, pollutant removal is done without adding chemicals; therefore, it remarkably reduces the sludge produced, and consequently reduces the cost of sludge handling. This method has been efficiently used to remove, up …
