(3) COLGATE MAXIMUM CAVITY PROTECTION (CMCP) 1450 ppm F as MFP and CaCO3; (4) WHITE GLO SMOKERS FORMULA (WGSF) 1000 ppm F as MFP and CaCO3; (5) CEDEL SPEARMINT (CS) 1000 ppm F as MFP and CaCO3 and (6) ARM & HAMMER (AH) 1100 ppm F as NaF and calcium sulfate/sodium ...
Amorphous calcium phosphate and calcium sulfate can transform to hydroxyapatite (c) and gypsum (d), respectively, by using humidity or water treatments. Although large single crystals without cracks have not been obtained, we believe that future improvements in crystallization control may provide a ...

Is magnesium oxide ionic or covalent? Is calcium a metal? Could two atoms of oxygen engage in ionic bonding? Why or why not? What is more reactive, calcium or magnesium? Do ionic bonds occur between metals and nonmetals? What chemical elements make iron rust? How many iron atoms are in...
As described in the 'Methods' section, Asp31 in both PEP-19 and PEP(P37G) was converted to Cys as a site for covalent modification with PROXYL to yield spin-labelled PEP-19SL and PEP(P37G)SL, respectively. The PRE effect was measured as the normalized cross-peak intensity ratio (Iox/...
Calcium is not found free in nature, but calcium compounds are common. Some of the most common compounds found on Earth are limestone (calcium carbonate - CaCO3), gypsum (calcium sulfate - CaSO4·2H2O), fluorite (calcium fluoride - CaF2) and apatite (calcium fluorophosphate - CaFO3P or cal...
