Copper water tubing has an outstanding history of corrosion resistance in most underground environments. Copper does not naturally corrode in most clays, chalks, loams, sands, and gravels. Certain aggressive soil conditions, however, can cause it to corrode. The basic prerequisite for corrosion is the presence of appreciable amounts of moisture.

Copper oxide nanoparticles were immobilized on quartz sand and their catalytic activity for the degradation of an organic dye was investigated. These nanoparticles, in free form, were shown previously to be efficient catalysts for the complete degradation of several organic water pollutants, without formation of hazardous byproducts and without the need for any type of …
A thermite mixture using Iron (III) oxideThermite is a high-temperature incendiary composition that can successfully reach temperatures of 2500 degrees Celsius. A thermite reaction--sometimes called a "Goldschmidt reaction"--refers to the very exothermic process occurring between a metal oxide such as Iron (III) oxide, Manganese (IV) oxide, or Copper (II) oxide, and a more reactive …
