Nevertheless, with respect to corrosion resistance, this deterioration effect can be compensated by the retard of the forward corrosion reaction of the substrate with water according to eq. (1). Therefore, it is expected that there exists equilibrium between the breach of coating compactness and ...
Alkaline earth metal ions, e.g., Mg+ and/or Ca+, are removed from alkali metal brines, e.g., NaCl, by use of a particulate, macroporous, anion exchange resin containing the in-situ reaction product of polymeric, amorphous, hydrous zirconium oxide and a source of POions, e.g., HPO....

The activation energy for the deuterium−hydrogen exchange reaction is estimated to be 51 ± 15 kJ/mol. Almost complete isotope exchange was observed by treating solid Mg(BH4)2 for 72 h at 172 °C with 42 bar of D2. Preliminary experiments indicate that under these conditions Ca(BH4)2 ...
