Sonohemijska sinteza i karakterizacija hidroksiapatita i poli(d,l-laktid-ko-glikolid)/hidroksiapatit kompozita
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2008)
U radu predstavljenom u ovoj magistarskoj tezi ultrazvučna metoda je iskorišćena za sintezu hidroksiapatita (HAp), usitnjavanje dobijenih aglomerata ultrazvučnim poljem visokog intenziteta i njihovo oblaganje poli(d,l-la ...
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 ...
XRD analysis of calcium phosphate and biocomposite calcium phosphate/bioresorbable polymer
(Recent Developments in Advanced Materials and Processes, 7th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS), Sep 12-16, 2005, Herceg Novi, Montenegro, 2006)
Composite biomaterials based on calcium phosphate ceramic due to their high bioactivity are of interest for biological application and bone tissue repair. Structural and microstructural parameters of inorganic constituent ...
Hidrotermalna sinteza nanostrukturnih oksidnih prahova i njihova karakterizacija
(Belgrade : University of Belgrade, Faculty of Technollogy and Metallurgy, 2009)
Usled razvoja i primene raznih naprednih materijala u nanokristalnom obliku dolazi do potrebe za uvođenjem novih tehnologija za sintezu nanočestičnih i nanostrukturnih materijala, koje su isplative za industrijsku proizvodnju ...
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 ...
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, ...
Surface properties of HAP particles obtained by hydrothermal decomposition of urea and calcium-EDTA chelates
(15th International Symposium on Ceramics in Medicine, Dec 04-08, 2002, Univ Technol, Sydney, Australia, 2003)
In this paper surface properties of calcium-hydroxyapatite, synthesized by modified hydrothermal reaction of urea and Ca(EDTA)(2-) in phosphate solutions, as well as the dependence of calcium hydroxyapatite dispersion ...
Analysis of in vivo substitution of bone tissue by HAp/PLLA composite biomaterial with PLLA of different molecular weights using FTIR spectroscopy
(Uetikon-Zuerich : Trans Tech Publ, 2000)
Hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial with PLLA of 50,000 and 430,000 g/mole molecular weight was studied in vivo. The biocomposite with PLLA of both molecular weights was implanted into mice and ...
