Nanocrystalline Apatites: Post-Immersion Acidification and How to Avoid It—Application to Antibacterial Bone Substitutes [PDF]
Bioengineering, 2023 Biomimetic nanocrystalline apatites analogous to bone mineral can be prepared using soft chemistry. Due to their high similarity to bone apatite, as opposed to stoichiometric hydroxyapatite for example, they now represent an appealing class of compounds ...

Evaluation of potential biomaterials for application in guide bone regeneration from Bacterial Nanocellulose/Hydroxyapatite [PDF]
Polímeros, 2023 Bacterial nanocellulose (BNC) membranes have interconnected porous nanostructures and excellent biocompatibility. Functionalizing these with calcium phosphate sources and metal ions confers optimized properties to the biomaterial.

Studies of Peculiar Mg-Containing and Oscillating Bioapatites in Sheep and Horse Teeth
Biomolecules, 2021 New types of biological apatites have been discovered in molar sheep and horse teeth and are divided in two types. In the first and more general type, the release of Mg ions is parallel to the changes in composition of apatite leading to a final ...

Acta Crystallographica Section B Structural Science, 2010 Certain complex structures are logically regarded as intergrowths of chemically or topologically discrete modules. When the proportions of these components vary systematically a polysomatic series is created, whose construction provides a basis for understanding defects, symmetry alternation and trends in physical properties.

Gold in biogenic apatites of the Baltic-Ladoga phosphorite basin
Записки Горного института, 2022 The distribution of gold in biogenic apatites from the Ordovician deposits in the northwest of the East European Platform shows that the maximum concentration of gold in apatites is found within the Ladoga-Baltic suture zone.
