Hydroxyapatite nanopowders prepared in the presence of zirconium ions
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 ...
Simultaneous thermal analysis and dilatometric study of HAp-LiFePO4 system
(Novi Sad : Faculty of Technology, University of Novi Sad, 2015)
Sintered hydroxyapatite bioceramics have been widely studied as a potential material for bone tissue reparation, however, concerning its microstructural and mechanical properties some limits were achieved at the moment. ...
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 ...
Radiation-induced degradation of hydroxyapatite/poly L-lactide composite biomaterial
(Radiation Physics and Chemistry, 2007)
The effects of gamma irradiation on the structure and properties of hydroxyapatite/poly L-lactide (HAp/PLLA) biomaterial have been investigated. Effects of radiation on microstructure, degradation of polymer part and thermal ...
Antibacterial activity of hydroxyapatite/silver nanocomposite
(Belgrade : Institute of Technical Sciences of SASA, 2010)
Hydroxyapatite containing silver nanoparticles (HAp/Ag) was synthesized by homogeneous sonochemical metod. Morphology of obtained particles was formed of micrometer-sized rod-like HAp with nanosized silver sphere-like ...
Surface modification of titanium implants by adherent hydroxyapatite/titanium oxide composite coatings using novel in-situ synthesis
(International Association of Physical Chemists, 2019)
The medical devices based on titanium and its alloys are widely used in the repair and replacement of a degraded or inhibited func-tion of locomotor system . Ti and its alloys exhibit high mechanical strength, good ...
FTIR study of biological hydroxyapatite
Poster presentation at the PHYSICAL CHEMISTRY 2010. 10th International Conference on Fundamental and Applied. Aspects of Physical Chemistry, Belgrade, Serbia, September 21-24, 2010
Lanthanide doped hydroxyapatite for multimodal imaging
(Belgrade : Serbian Ceramic Society, 2018)
Lantanide dual-doped hydroxyapatite (HaP:Ln) is currently the subject of numerous studies in reconstructive medicine. Designed in form of hybrid nanoparticles which have magnetic and luminescent properties HaP:Ln (where ...
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 ...
Multifunctional hydroxyapatite and poly(D,L-lactide-co-glycolide) nanoparticles for the local delivery of cholecalciferol
Cholecalciferol, vitamin D3, plays an important role in bone metabolism by regulating extracellular levels of calcium. Presented here is a study on the effects of the local delivery of cholecalciferol (D3) using nanoparticulate ...
