This work is devoted to the preparation of carbonated calcium phosphate apatites. The aim
was to produce dense ceramics containing various and precisely controlled amounts of …

Through the example of two HA ceramics prepared from two HA powders (HAD and HAL),
we explored the relation between the physico-chemical qualities of the initial HA powder …

Silicate-substituted hydroxyapatite scaffolds containing multiscale porosity are
manufactured. Model parts containing macropores of five cross-sectional geometries (circle …

Silicated hydroxyapatite powders (Ca10 (PO4) 6-x (SiO4) x (OH) 2-x; SixHA) were
synthesized using a wet precipitation method. The sintering of SixHA ceramics with 0⩽ x⩽ 1 …

The effects of heat treatment of calcium hydroxyapatite (Hap) on the protein adsorption
behavior were examined using typical proteins of bovine serum albumin (BSA: isoelectric …

Fibronectin (Fn) and type I collagen (Col) were immobilized on a surface of a hydroxyapatite
(HAP) ceramic by coprecipitation with calcium phosphate in a supersaturated calcium …

The lifetime of bone implants inside the human body is directly related to their
osseointegration. Ideally, future materials should be inspired by human tissues and provide …

A comparative study of in vitro bioactivity of hydroxyapatite (HA) and silicon-doped
hydroxyapatite (SiHA) has been carried out by immersion in a cell culture medium with or …

Surface quality and biocompatibility were critical properties of bone scaffolds. Fabrication
and biological properties of porous hydroxyapatite (HA) scaffolds made by extrusion …
