The A02 team will develop structurally controlled materials that are lightweight with high flexibility and mechanical strength. These materials will be constructed from organic molecules and abundant natural inorganic constituents, such as calcium carbonate, calcium phosphate, and iron oxides. Fine control of the interface and hierarchical frameworks between the organic molecules and inorganic constituents at atomic and molecular-scales will be key to constructing materials with the desired characteristics. In order to archive this purpose, the A02 team will use the synthetic and analytical techniques investigated by the A01 team. The A03 team will then apply the constructed materials to novel functions.
