Study shows
how calcium carbonate forms composites to make strong materials such as in shells and pearls
To find out
how calcium carbonate incorporates proteins or other strength - building components, the team turned to atomic force microscopy, also known as AFM, at the Molecular Foundry, a DOE Office of Science User Facility at Lawrence Berkeley National Laboratory.
Understanding
how calcium carbonate turns into various minerals could help scientists control its formation to keep carbon dioxide from getting into the atmosphere.
Using a powerful microscope that lets researchers see the formation of crystals in real time, a team led by the Pacific Northwest National Laboratory found that negatively charged molecules — such as carbohydrates found in the shells of mollusks — control where, when, and
how calcium carbonate forms.
