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 ...
Chitosan-PLGA polymer blends as coatings for hydroxyapatite nanoparticles and their effect on antimicrobial properties, osteoconductivity and regeneration of osseous tissues
(Materials science & engineering. C, Materials for biological applications, 2016)
Composite biomaterials comprising nanostructured hydroxyapatite (HAp) have an enormous potential for natural bone tissue reparation, filling and augmentation. Chitosan (Ch) as a naturally derived polymer has many physicochemical ...
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 ...
Chitosan oligosaccharide lactate coated hydroxyapatite nanoparticles as a vehicle for the delivery of steroid drugs and the targeting of breast cancer cells
(Royal Society of Chemistry, 2018)
Low targeting efficiency and fast metabolism of antineoplastic drugs are hindrances to effective chemotherapies and there is an ongoing search for better drugs, but also better carriers. Steroid derivatives, 3β-hydroxy-1 ...
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 ...
