The plate skeleton morphology of the sand dollar is composed of a modular system of polygonal plates that are linked together at the edges by finger-like calcite protrusions. This system of joints ...

Studying calcite is important as it has broad relevance in several ways. When calcium carbonate is synthesized, it transforms carbon dioxide (CO 2) into solid carbonate, the final reaction product ...

"What we found, instead, is that 40-100 nanometer amorphous calcium carbonate particles aggregate into the final morphology. One starts converting to crystalline calcite, then another immediately ...
