Preparation of novel bioactive nano-calcium phosphate–hydrogel composites
Preparation novel bioactive nano-calcium phosphate–hydrogel composites
2010/10/12
Nano-sized hydroxyapatite (nHA) and carbonate-substituted hydroxyapatite (nCHA) particles were incorporated into a poly-2-hydroxyethylmethacrylate/polycaprolactone (PHEMA/PCL) hydrogel at a filler con...
External pressure in the hardening of phosphate in tribofilm on iron surfaces
Antiwear additives Hardness External pressure Transition metals
2009/12/14
Purpose: In the present work we consider our (in progress) spectroscopy study of zinc and iron phosphates under the influence external high pressure to determine zinc ion change coordination from tetr...
Chemical Synthesis, Characterization, and Biocompatibility Study of Hydroxyapatite/Chitosan Phosphate Nanocomposite for Bone Tissue Engineering Applications
Chemical Synthesis Biocompatibility Hydroxyapatite/Chitosan Phosphate Nanocomposite Bone Tissue Engineering Applications
2009/9/2
A novel bioanalogue hydroxyapatite (HAp)/chitosan phosphate (CSP) nanocomposite has been synthesized by a solution-based chemical methodology with varying HAp contents from 10 to 60% (w/w). The interf...
Porous hydroxyapatite and biphasic calcium phosphate ceramics promote ectopic osteoblast differentiation from mesenchymal stem cells
calcium phosphate ceramics porous structure osteogenesis
2010/1/19
Because calcium phosphate (Ca–P) ceramics have been used as bone substitutes, it is necessary to investigate what effects the ceramics have on osteoblast maturation. We prepared three types of Ca–P ce...
Effect of zinc phosphate chemical conversion coating on corrosion behaviour of mild steel in alkaline medium: protection of rebars in reinforced concrete
steel corrosion rebar protection alkaline medium phosphate coating hydroxyapatite
2010/10/12
We outline the ability of zinc phosphate coatings, obtained by chemical conversion, to protect
mild steel rebars against localized corrosion, generated by chloride ions in alkaline media. The corrosi...
