To assess the mechanical properties of magnesium phosphate cement (MPC) mortar, magnesia was used as a binder, while ordinary Portland cement (OPC) was used for the control. The oxide composition of binders was measured by X-ray fluorescence as given in Table 1. The fineness of magnesia and OPC was 5,089 and 3,120 cm 2 /g, respectively. To ...

Jun 24, 2019· The mechanical properties of human bone, additively manufactured PGF 10 composites, and a continuous PGF/PLA composite are listed in Table 2. Comparing with the mechanical properties of cortical bones, the (dry) flexural strength of the PGF 10 composite is a close approximation, while the flexural modulus is much lower.

The aim of the present study was to compare the mechanical properties of arterial and venous tissue-engineered vascular constructs produced by the self-assembly approach using cells extracted from either the artery or vein harvested from the same human umbilical cord.

Co-continuous composites consisting of a porous calcium phosphate matrix (hydroxyapatite, HA, or β-tricalcium phosphate, TCP) filled with poly(d,l-lactide) (PDLLA) were produced with two different methods: in situ polymerization of d,l-lactide monomer inside the matrix, or infiltration of the matrix with molten polymer. The influence of the calcium phosphate matrix as well as the ...

For this reason, zirconia (ZrO2) and alumina (Al2O3) have been associated to the calcium phosphate in order to improve the mechanical properties of the resulting bioceramic.

In this study, we show how the infiltration of biphasic calcium phosphate scaffolds with poly(ε-caprolactone) improves their mechanical properties. It was found that the polymer effectively contributes to energy to failure enhancement in bending, compressive and tensile tests.

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium in the gastrointestinal (GI) tract.
