Morphology-Dependent Transformation of Dicalcium Phosphate Dihydrate (DCPD) to Octacalcium Phosphate (OCP) and Its Stability in Simulated Physiological Fluids [PDF]
MoleculesCalcium phosphate (CaP) materials are biocompatible and non-toxic to the body. However, they lack biointegration, exhibit a low resorption rate and can cause fibrous encapsulation throughout the implant material.

Apatite textural and geochemical insights into the petrogenesis of intrusive rocks [PDF]
Scientific ReportsApatite is widely used as an indicator mineral to reflect the characteristics and petrogenesis of host magma. In this study, we present apatite geochemical and in-situ Sr–Nd isotopic data of monzogranite, granodiorite and dioritic enclave in the eastern ...

Production, by co-grinding in a media mill, of porous biodegradable polylactic acid-apatite composite materials for bone tissue engineering [PDF]
, 2009 This paper presents the results of a study of the production of porous biodegradable composite materials by co-grinding, followed by scaffolding. Dry powders of polylactic acid and nanocrystalline carbonated apatite, analogous to bone mineral were co ...

The location of cationic substitutions in carbonated biomimetic apatites significantly affects crystal nanomechanics [PDF]
Scientific ReportsBone and teeth are comprised of carbonate-substituted apatites with cationic substitutions, like sodium and potassium. Cations substitute for calcium in the apatite lattice but it is unclear whether they substitute for Ca(1) or Ca(2).

The Identification and Synthesis of Lead Apatite Minerals Formed in Lead Water Pipes [PDF]
Journal of Chemistry, 2016 Phosphate is added to drinking water in the UK to minimise the release of lead from lead water pipes. The phosphate encourages the formation of insoluble lead apatites on the walls of the pipe. Hydroxylpyromorphite Pb5(PO4)3OH is the lead apatite that is

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 ...

Light δD apatites reveal deep origin water in North China Craton intracontinental granites and basalts [PDF]
Nature CommunicationsWater is essential to the formation of intracontinental granites, but its origin remains elusive. Here we address this scientific problem by analyzing D/H isotopes of apatites, hydrous minerals in Jurassic and Early Cretaceous granites and basalts from ...

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.
