Synthesis and characterization of biphasic calcium phosphate/poly-(DL-lactide-co-glycolide) biocomposite
(Current Research in Advanced Materials and Processes, 6th Conference of the Yugoslav-Materials-Research-Society, Sep 13-17, 2004, Herceg Novi, Montenegro, 2005)
In this paper we report the results on synthesis of a composite biomaterial based on biphasic calcium phosphate (BCP) and poly-(DL-lactide-co-glycolide) (DLPLG). Besides, we have investigated the influence of new synthesis ...
Microstructure and mechanical properties of hot-pressed hydroxyapatite/poly-L-lactide biomaterials
(Trans Tech Publications, Ltd., 2000)
Effects of the hot pressing parameters on the designing of structures and properties of hydroxyapatite/poly-L-lactide (HAp/PLLA) biocomposite blocks have been studied. Interdependences of temperature, pressure and time of ...
In vitro and in vivo investigation of collagen - C-60(OH)(24) interaction
(Trans Tech Publications Ltd., 2004)
In this paper both theoretical and experimental approach to a possible interaction between collagen hydrolyzate and fullerole C-60(OH)(24) have been considered. In vitro and in vivo experiments were performed. Based on ...
The influence of tribophysical activation on non-isothermal sintering of BaTiO3 ceramics
