"Ant-nest" corrosion is a specific type of premature failure of copper tubes used in air-conditioning units causing the loss of refrigerant liquid and consequent environmental pollution. It is known that attack requires the simultaneous presence of moisture, oxygen, and a corrodent, usually formic acid. This type of corrosion occurs in thin-walled copper pipes, especially when copper is deoxidized high residual phosphorus. A study has been made of the copper corrosion products formed by the acti...

AbstractThere are still many unresolved issues concerning the efficiency of electrochemical realkalisation and electrochemical chloride removal as electrochemical rehabilitation methods for corroding reinforced concrete structures. The present paper seeks to answer a number of questions which, though seemingly elementary, continue to arouse controversy in scientific, technical and economic communities, despite the vast amount of work that has been devoted to research on corrosion in concrete emb...

Abstract The main reason for the premature failure of reinforced concrete structures (RCS) is corrosion of the reinforcements. The use of new mortars based on activated fly ash, an alternative to conventional portland cement, requires extensive research in order to check its passivating properties for reinforcements and the instability or permanence of the passive state achieved. The present paper studies this objective, analysing the passivating capacity of specimens manufactured with three dif...

AbstractCarboxylic acids of low molecular weight, such as formic, acetic, propionic and butyric acids, as well as other acids (n-pentanoic, hexanoic, heptanoic, etc.), are present in rain, snow, clouds and particulate matter. They contribute about 16–36% of rain acidity. It is estimated that ∼64% of formic acid and ∼88% of acetic acid are in the vapour phase. Carboxylic acids are produced by the combustion of biomass, and analyses of the smoke from fire events reveal concentrations of about 300–...

Research and development has made it possible to use metallic interconnects in solid oxide fuel cells (SOFC) instead of ceramic materials. The use of metallic interconnects was formerly hindered by the high operating temperature, which made the interconnect degrade too much and too fast to be an efficient alternative. When the operating temperature was lowered, the use of metallic interconnects proved to be favourable since they are easier and cheaper to produce than ceramic interconnects. Howev...
