An innovative, quick and convenient labeling method for the investigation of pharmacological behavior and the metabolism of poly(DL-lactide-co-glycolide) nanospheres
(Bristol : IOP Science, 2009)
Nanoparticles of poly(DL-lactide-co-glycolide) (PLGA) in the size range 90-150 nm were produced using the physicochemical method with solvent/non-solvent systems. The encapsulation of the ascorbic acid in the polymer matrix ...
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 ...
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 ...
Polyaniline as possible anode materials for the lead acid batteries
(Elsevier, 2008)
Electrochemically formed thin film polyaniline (PANI) anode and lead dioxide (PbO2) cathode, obtained from sulfuric acid solution, for potential applications as electrode materials in PANI|H2SO4|PbO2 aqueous based rechargeable ...
Formation of magnesium titanates
(Springer, 2009)
The paper examines the phase formation in the mechanochemical treatment and subsequent annealing of TiO 2 and MgO mixtures. It is established that the MgTiO 3 phase forms during annealing of the above powder mixtures at ...
Structural analysis of Zn2TiO4 doped with MgO
(Springer, 2009)
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
Injectable polydimethylsiloxane-hydroxyapatite composite cement
(Bio-Medical Materials and Engineering, 2003)
An injectable polydimethylsiloxane/hydroxyapatite (PDMS/HAp) composite cement was synthesised using linear PDMS and HAp (particles of about 100 nm in size) of different mass fractions. The effect of HAp mass fraction (5-60 ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Elsevier, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm-3 HClO4, saturated with H2 containing 100 ppm CO, was examined with rotating disc ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb0.9Sn0.1Te doped with 0.4 at.%, ...
Photopyropiezoelectric elastic bending method
(AIP Publishing, 2003)
A method of investigation of semiconductors and metal–semiconductor structures based on two techniques: The elastic bending technique and pyropiezoelectric (PPE) technique was presented. The method was demonstrated on a ...
