Some fig trees don’t just grow fruit—they grow stone, too. By converting carbon dioxide into calcium carbonate, they may offer a powerful, long-lasting way to trap carbon. Credit: Shutterstock In a ...

The calcium carbonate is formed both on the surface of the tree and within the wood structures, likely as microorganisms decompose crystals on the surface and also, penetrate deeper into the tree.

The conversion of sodium carbonate to sodium carbonate monohydrate and the subsequent growth of monohydrate crystals have been investigated by carrying out in situ measurements of particle size ...
