The present work investigates, in situ, the in vitro bioactivity of partially crystallized 45S5 Bioglass (BG) as a function of immersion time in a simulated body fluid (SBF) using atomic force microscopy (AFM). The results obtained for the crystallized BG were compared to those of hydroxyapatite c- and a-faces. The calcium phosphate layer grows on the crystallized 45S5 B by multiple two-dimensi...

We report the synthesis of a range sodium-carbonate co-substituted hydroxyapatite compositions with sodium and measured carbonate contents ranging from approximately 0.4–0.8 ​wt% 4.4–14.2 ​wt%, respectively, via aqueous precipitation reaction between calcium hydroxide, phosphoric acid either or hydrogen-carbonate. A subsequent heat treatment in dry CO2 at 600 ​°C allowed for Na–CO3 apatite cont...

The feasibility of soft mechanochemical synthesis was studied here for hydroxyapatite with various types substitution. It shown that this method allows obtaining hydroxyapatites substituted copper or iron cations and cosubstituted zinc silicate groups. Thermal stability the synthesized samples evaluated. found to preserve phase homogeneity material, temperature during preparation ceramic produc...

BACKGROUND The interaction between Ca-HAP and Pb(2+) solution can result in the formation of a hydroxyapatite-hydroxypyromorphite solid solution [(PbxCa1-x)5(PO4)3(OH)], which can greatly affect the transport and distribution of toxic Pb in water, rock and soil. Therefore, it's necessary to know the physicochemical properties of (PbxCa1-x)5(PO4)3(OH), predominantly its thermodynamic solubility ...

The scaffolds, which morphologically and physiologically mimic natural features of the bone, are a high demand for regenerative medicine. To address this challenge, bioactive porous silicon/wollastonite (SC) scaffold has been developed potential bone tissue engineering applications. Additive manufacturing through selective laser melting approach exploited to fabricate computer-aided designed sc...
