J Mater Sci Mater Med. 2003 Jul;14(7):617-22. doi: 10.1023/a:1024075008165.

We investigated the microstructural changes on an atomic length scale during thermal decomposition process of Ca-deficient hydroxyapatite (Ca-def HAp) by high-resolution transmission electron microscopy (HRTEM). Ca-def HAp was prepared by hydrolysis of alpha-tricalcium phosphate. The Ca-def HAp had a...

J Mater Sci Mater Med. 2002 Feb;13(2):191-5. doi: 10.1023/a:1013886130805.

It was the purpose of this investigation to prove the biomechanical properties, the osteoconductive capacity and the degradation rate of alpha tricalcium phosphate (alpha TCP), a neutralized glass ceramics (GB9N) and a composite material (GB9N+copolymers). In a weight-bearing animal...

Incorporation of a controlled-release glass into a calcium phosphate cement.

J Mater Sci Mater Med. 1999 Apr;10(4):215-8. doi: 10.1023/a:1008954011349.

A so-called controlled-release glass was synthesized occurring in the system CaO-Na2O-P2O5. A certain sieve fraction of this glass was incorporated in a calcium phosphate cement, of which the powder contained alpha-tricalcium phosphate (alpha-TCP), dicalcium phosphate (DCP) and precipitated hydroxyapatite...

Monitoring the setting of calcium-based bone cements using pulse-echo ultrasound.

J Mater Sci Mater Med. 2002 Dec;13(12):1135-41. doi: 10.1023/a:1021181702807.

We present a new technique, based on pulse-echo ultrasound, for monitoring the entire setting process of injectable bone cement. This research has been motivated by the lack of satisfying standards. The main problem with existing standards is the subjectivity,...
