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, ...
Mechanochemically induced amorphous/crystalline phase transition in the Bi4Ti3O12 compound
(Elsevier, 2009)
Concurrent milling of Bi4Ti3O12 was carried out in a planetary ball mill with hardened-steel 13 or 6 mm diameter balls with a goal to investigate how the system responds to the constrains imposed by milling. Milling intensity ...
Far infrared study of impurity local modes in palladium-doped PbTe and PbSnTe
(Elsevier, 2009)
PbTe and Pb0.85Sn0.15Te single crystals, doped with Pd, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and 300 K. The experimental spectra were numerically ...
Analysis of nonisothermal sintering of zinc-titanate ceramics doped with MgO
(Springer, 2008)
The aim of this work is to analyze nonisothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO 2, and MgO (0, 1.25, and 2.5%) are mechanically activated for 15 ...
Sintering of mechanically activated Zno-TiO 2 powders
(Springer, 2008)
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...
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 ...
Gamma irradiation processing of hydroxyapatite/poly-L-lactide composite biomaterial
(Radiation Physics and Chemistry, 2003)
Effects of gamma irradiation on structure and physicochemical properties of the hydroxyapatite/poly-L-lactide (HAp/PLLA) composite were studied in this paper. Since the morphology of HAp/PLLA is very sensitive to gamma ...
Poly(DL-lactide-co-glycolide) nanospheres for the sustained release of folic acid
(American Scientific Publishers, 2008)
Biodegradable polymers have become the materials of choice for a variety of biomedical applications. In particular, poly(DL-lactide-co-glycolide) nanoparticles have been studied as a material for drug delivery with the ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Čačak : Technical Faculty, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, Ti02 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Progress in Advanced Materials and Processes, 5th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS 2003), Sep 15-19, 2003, Herceg Novi, Yugoslavia, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
