Hydrothermal synthesis of nanosized pure and cobalt-exchanged hydroxyapatite
(Philadelphia : Taylor & Francis, 2009)
Pure and cobalt-exchanged hydroxyapatite (HAp and CoHAp) powders were synthesized by hydrothermal method. X-ray diffraction (XRD), Raman spectroscopy, particle size analysis, inductively coupled plasma (ICP) emission ...
Predictive modeling of the mechanical properties of particulate hydroxyapatite reinforced polymer composites
(Wiley, 2002)
The influence of particle geometry and volume fraction on the mechanical properties of a hydroxyapatite (HAp) particulate reinforced polymer (poly-L-lactide and collagen) matrix composite was investigated through finite-element ...
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 ...
Interaction of biomaterial containing calcium hydroxyapatite/poly-l-lactide with simulated body fluid
(Niš : University of Niš, Faculty of Medicine; Department of the Serbian Medical Society Niš, 2011)
The purpose of biomaterials is to replace a part or a function of the body in a safe, physiologically and economically acceptable way. The process of the reconstruction of bone defects has always been a big problem in ...
Processing Route to Fully Dense Nanostructured HAp Bioceramics: From Powder Synthesis to Sintering
(Hoboken, NJ : John Wiley & Sons, 2012)
The study is devoted to the processing of hydroxyapatite (HAp) nanopowder to develop fully dense nanostructured bioceramics by pressureless sintering. The sintering behavior of stoichiometric HAp prepared by hydrothermal ...
Influence of ultrasonic processing on the macromolecular properties of poly (D,L-lactide-co-glycolide) alone and in its biocomposite with hydroxyapatite
(Ultrasonics Sonochemistry, 2010)
In this work poly(D,L-lactide-co-glycolide) (PLGA) and a poly(D,L-lactide-co-glycolide)/hydroxyapatite (PLGA/HAp) composite processed in an ultrasonic field at higher (25 degrees C) and lower (8 degrees C) temperatures ...
Mechanochemical synthesis of nanostructured fluorapatite/fluorhydroxyapatite and carbonated fluorapatite/fluorhydroxyapatite
(Journal of Solid State Chemistry, 2004)
Powder mixture of Ca(OH)(2)-P2O5-CaF2 were milled in planetary ball mill. A carbonated fluorhydroxyapatite, FHA Ca-10(PO4)(1-y)(CO3)(y)(PO4)(5)(OH)(2-2x1)(F)(2x1) was formed after 5 h of milling and carbonated fluoroapatite ...
Inert atmosphere processing of hydroxyapatite in the presence of lithium iron phosphate
(Journal of the European Ceramic Society, 2018)
The present study describes sintering behaviour of hydroxyapatite (HAp) upon addition of lithium iron phosphate (LFP) (1-10 wt.%) system in inert (Ar) atmosphere. The interaction between materials and melting of LFP ...
Evaluation of hot-pressed hydroxyapatite/poly-L-lactide composite biomaterial characteristics
(Journal of Biomedical Materials Research. Part B: Applied Biomaterials, 2004)
Hydroxyapatite/poly-L-lactide (HAp/PLLA) is a ceramic/polymer composite, whose application as a resorbable biomaterial for the substitution and repair of hard bone tissue is widely promising in orthopedic, oral, maxillofacial, ...
Hydroxyapatite nanopowders prepared in the presence of zirconium ions
(Elsevier, 2014)
Hydroxyapatite nanopowders were prepared in the presence of different concentrations of zirconium ions. Such crystallization conditions yielded significantly reduced particle size and increased specific surface area. Cell ...
