Hydroxyapatite/poly-L-lactide (Collagen) biocomposite with poly-L-lactide of different molecular weights
(Weinheim : Wiley-VCH Verlag, 2000)
In this communication we describe the preparation of HAp/PLLA biocomposites by hot pressing of HAp powder with PLLA of different molecular weights, with and without the addition of collagen. We made PLLA of low molecular ...
Nanosilica/PMMA composites obtained by the modification of silica nanoparticles in a supercritical carbon dioxide-ethanol mixture
(Springer, 2009)
Nanosilica/poly(methyl methacrylate) (PMMA) composites are used to improve the mechanical properties of neat PMMA polymer. In order to obtain superior mechanical properties, it is essential to achieve good bonding between ...
Estimation of elastic properties of a particulate polymer composite using a face-centered cubic FE model
(Elsevier, Amsterdam, 2004)
A three-dimensional (3D) finite element (FE) unit cell model is applied to studies on the elastic properties of ceramic spherical particle-polymer composite. In this model, hydroxyapatite particles (HAp) are assumed to be ...
Molecular spectroscopy analysis of the substitution of bone tissue by HAp/PLLA composite biomaterial
(IOS Press, 2004)
Due to its pronounced osteoinductive properties, calcium hydroxyapatite (HAp) has been widely used in medicine. Bioresorptive poly-L-lactide (PLLA) as a polymer biomaterial has been also used extensively in medicine for ...
Biological evaluation of hydroxyapatite/poly‐L‐lactide (HAp/PLLA) composite biomaterials with poly‐L‐lactide of different molecular weights intraperitoneally implanted into mice
(IOS Press, 2004)
Histopathologic analysis of the tissue with HAp/PLLA implants was made and the leukocyte formula and chemiluminescence response of peritoneal phagocytes 2, 7 and 12 weeks after intraperitoneal implantation studied. Implants ...
Repair of Bone Tissue Affected by Osteoporosis with Hydroxyapatite-Poly-L-lactide (HAp-PLLA) with and Without Blood Plasma
(SAGE Publications, 2005)
The aim of this study is to examine the reparatory ability of the synthetic biomaterial hydroxyapatite-poly-L-lactide (HAp-PLLA), the replacement of alveolar ridge, and rehabilitation of bone defects caused by osteoporosis, ...
Synthesis and Characterization of Hydroxyapatite-Collagen Biocomposite Materials
(Trans Tech Publications, Ltd., 2003)
Hydroxyapatite-collagen composite is a prosperous biomaterial in reconstructive surgery for the reparation of defects within human hard tissue. Within this research, three-dimensional blocks of HAp/collagen composite ...
The influence of hydroxyapatite modification on the cross-linking of polydimethylsiloxane/HAp composites
(Elsevier, 2004)
Hydroxyapatite (HAp) was modified by the action of various hydrophobic agents based on silicon-containing compounds. The influence of the type of applied agent on the thermodynamic and kinetic parameters of the cross-linking ...
Aerosol processing of fine Ag:(Bi,Pb)2223 composite particles
(Elsevier, 2004)
This paper represents an attempt in the obtaining of metal–ceramic composite precursor powders in the Ag:Bi-based superconductor system with uniform distribution of comprised phases through spray pyrolysis method. The ...
Biphasic calcium phosphate coated with poly-d,l-lactide-co-glycolide biomaterial as a bone substitute
(Elsevier, 2007)
A calcium phosphate/poly-d,l-lactide-co-glycolide (BCP/DLPLG) composite biomaterial was synthesized in the shape of spherical granules (150–200 m) and nanostructured particles (30–40 nm) by an emulsification/evaporation ...
