Apply calcium chloride immediately after spring shaping, before the road has dried from the spring rains. Although liquid calcium chloride makes unpaved roads hard, it can make paved roads slick. Distributor trucks should reduce speed about 100 feet (30 meters) before paved areas and use extreme caution treating the remaining unpaved area.

Paramagnetism of Transition Metal Salts | Chemdemos

Paramagnetism is when a substance is weakly attracted to a magnetic field. It occurs when there are unpaired electrons in the substance. Paramagnetism is most easily observed in the salts of some of the first row transition metals (manganese through nickel). The se metal ions have unpaired electrons in degenerate d orbitals as predicted by Hund''s rule and thus exhibit paramagnetism.

CUI: An In-Depth Analysis - Insulation Outlook …

2006/11/1· Corrosion under insulation (CUI) is a well-understood problem, and mitigation methods are well established. However, it is pervasive and continues to cost the process industry many millions of dollars annually. In 2002 a large chemical company spent over $5 million dollars replacing 304 stainless steel equipment because of chloride stress corrosion cracking (CSCC) under insulation.1

Hidden Dangers | The Conscious Cook

DOE has come up with an ingenious plan to dispose of its troublesome tons of nickel, copper, steel, and aluminum. It wants to let scrap companies collect the metal, try to take the radioactivity out, and sell the metal to foundries, which would in turn sell it to manufacturers who could use it for everyday products: pots, pans, forks, spoons, even your eyeglasses.
