Their properties can be adjusted very specifically to catalyze a desired reaction based on their precise tunability, both in terms of molecular structure ... Instead, the cobalt ions detach ...

they created a molecular solid structure that causes the cobalt complex to precipitate out of the solution while leaving the nickel one dissolved. Their work showed that the carbonate anion ...

By introducing a specific negatively charged molecule, or anion, like carbonate into the system, they created a molecular solid structure that causes the cobalt complex to precipitate out of the ...
