Application analysis of micro and nano composites in restoring of bone tissue of the jaw
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Application of synthetic polymer biomaterials is very often used in biomedicine and
dentistry. That’s why the need for creating the new polymer biomaterials is more and more
obvious. Hydroxy-apatite, as a natural constituent ...
Structural and electrical properties of the 2Bi2O3·3ZrO2 system
(Journal of Solid State Chemistry, 2008)
Powder mixtures of α-Bi2O3 (bismite) and monoclinic m-ZrO2 (baddeleyite) in the molar ratio 2:3 were mechanochemically and thermally treated with the goal to examine the phases, which may appear during such procedures. The ...
Fabrication, in vitro degradation and the release behaviours of poly(DL-lactide-co-glycolide) nanospheres containing ascorbic acid
(Colloids and Surfaces. B: Biointerfaces, 2007)
Ascorbic acid (vitamin Q is essential for preserving optimal health and is used by the body for many purposes. The problem is that ascorbic acid easily decomposes into biologically inactive compounds making its use very ...
Poly(lactide-co-glycolide)-based micro and nanoparticles for the controlled drug delivery of vitamins
(Bentham Science Publishers, 2009)
Controlled drug delivery systems and polymeric carriers have undergone significant development in recent years. Polymers like polylactides (PLA), polyglycolides (PGA), poly(lactide-co-glycolides) (PLGA), are approved by ...
Influence of different degradation medium on release of ascorbic acid from poly(D,L-lactide-co-glycolide) nano- and microspheres
(Springer, 2009)
The major goals of the present study were to examine the effects of the type of release medium on the resulting drug release kinetics and to get further insight into the underlying drug release mechanisms. Spherical micro ...
Biodegradable composites based on nanocrystalline calcium phosphate and bioresorbable polymers
(Taylor & Francis, 2008)
Nanocrystalline calcium phosphates (NC CP) are suitable for the synthesis of CP/bioresorbable polymer composite biomaterials for the application in bone engineering. There are different forms of NC CP/ bioresorbable polymers ...
Mechanochemical synthesis of nanocrystalline titanium monoxide
(Elsevier, 2008)
Nanocrystalline cubic titanium monoxide, TiOx (0.92 < x < 1.19), with mean crystallite size of ≈ 6 nm, was synthesized by mechanochemical treatment of Ti and TiO2 (rutile) powder mixtures with molar ratios of 1:1, ...
Rapid formation of high Tc phase in Bi-Pb-Sr-Ca-Cu-O system
(Elsevier, 2000)
The preparation of high purity 140nm sized Bi-Pb-Sr-Ca-Cu-O particles is based on thermal decomposition of aerosol generated ultrasonically (at 1.7Mhz) from IM nitrate precursor which contain organic additive. Particle ...
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 ...
Nanostructured ZrO2 powder synthesized by ultrasonic spray pyrolysis
(Surface Review and Letters, 2007)
The synthesis of nanostructured zirconia particles from aqueous colloidal dispersion of zirconia (zirconia sol) was carried out by ultrasonic spray pyrolysis method. The morphology of these nanostructured particles was ...
