Establishing a physical and chemical framework for Amorphous Calcium Carbonate (ACC) biomineralization
… pathways that involve metastable intermediates. Biogenic calcium carbonate minerals are now recognized to develop by aggregating molecules or clusters to form amorphous phases that later transform to one or more crystalline polymorphs. Amorphous calcium carbonate (ACC) is now recognized as a …

Response and resilience of estuarine benthic ecosystems to anthropogenic pressures
… structure and function, and assessed whether biogenic calcium carbonate (CaCO₃) would alter the response. Declines in macrofauna biodiversity (abundance and species richness), reduced benthic NPP and impaired nutrient cycling occurred along the eutrophication gradient. CaCO₃ did not alter the …

3D printing of bone scaffolds using powders derived from biogenic sources
… for the regeneration of bones. At this purpose, calcium phosphates derived from natural sources are very interesting because they are more similar to the bone mineral and possess better bioactivity. Indeed, the bone mineral is different from synthetic hydroxyapatite as it is non-stoichiometric, …
