  •  Does It Need to Be Calcium? (9+ / 0-)

    Clearly the focus of the study was on the way to catalyze a reaction using nanoparticle nickel in producing calcium carbonate, which was known to be the reaction product of the sea urchins.  Does that final reaction product need to be calcium at all?  What does appear to be necessary is a +2 ion to combine with the -2 carbonate ion to produce a precipitate insoluble in slightly acidic water.  It appears that zinc might fit that bill, which woudl be a good end use for all of those pennies we've produced over the years.  So, what sort of waste byproduct do we have which can readily convert to a +2 ion is available for combination with the carbonate formed by the reaction with nano nickel?
