Barium-zinc-titanate ceramics
(Kiev : National Academy of Sciences of Ukraine (NASU); Frantsevych Institute for Problems of Materials Science of NASU; National Technical University of Ukraine "KPI"; Ukrainian Materials Science Society; INTEM LTD, 2010)
Starting mixtures of BaCO3, ZnO and TiO2 powders were mechanically activated in a planetary ball mill for various periods of time. The powders obtained were sintered nonisothermally to temperatures between 1100 and 1300°C ...
Microstructure evolution and sintering kinetics of ZnO
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The aim of this paper was to analyse the sintering kinetics and microstructure evolution of ZnO. Powder was isothermally sintered (15, 30, 60, 90 and 120 minutes) in the temperature range from 800 to 1200oC. The values of ...
Electrochemical characterization of polyaniline electrode for use in electrochemical power sources
(Nice : International Society of Electrochemistry, 2010)
Polyaniline (PANI) electrode was formed by electrochemical synthesis on graphite under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm-3 HCl and 0.25 mol dm-3 aniline. ...
FTIR study of biological hydroxyapatite
(Belgrade : Society of Physical Chemists of Serbia, 2010)
In this study Fourier transform infrared (FTIR) spectroscopy was used to resolve setting of carbonate ions in biological hydroxyapatite (BHAp). Even though preliminary XRPD results indicate that BHAp is B-type carbonated ...
Preparation of LiFePO4/C composites by co-precipitation in the presence of stearic acid
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The olivine type compositions LiMPO4 (M = Fe, Mn, Co) are among the most attractive materials for the positive electrode of lithium-ion battery. The benefits of using LiFePO4 are excellent cycle life, high structural ...
Barium titanate stannate functionally graded materials: Choosing of the Ti/Sn concentration gradient and the influence of the gradient on electrical properties
(Hoboken, NJ : John Wiley & Sons, 2010)
Barium titanate stannate (BaTi1-xSnxO3, BTS) functionally graded materials (FGMs) with different Ti/Sn concentration gradients were prepared by the powder processing method followed by sintering. Firstly, with the aim of ...
Evaluation compensation of an osteoporotic rat bone with Ca/Co-HAp nanoparticles
(Belgrade : Institute of Technical Sciences of SASA, 2010)
This study examined the role of Ca / Co-HAp nanoparticles on time distance in regeneration of osteoporotic alveolar bone in rats by biochemical blood markers analysis (ALP, Ca, Mg, P) and through histochemical analysis. ...
Perspectives of Novel Poly(D,L-lactide-co-glycolide)/hydroxyapatite core-shell nanoparticles as carriers of antibiotics
(Davos: AO Research Institute Davos, 2010)
Local drug delivery for the treatment of infectious bone tissue diseases is a high importance topic in the field of biomedicine for a last two decades. [1] In general, some of the main problems related to controlled drug ...
Determination of clindamycin in pig plasma after implantation of poly(D,Llactide-co-glycolide)/hydroxyapatite/clindamycin core–shell nanosphere by liquid chromatography-tandem mass spectrometry
(Belgrade : Institute of Technical Sciences of SASA, 2010)
Clindamycin was determined in pig plasma by liquid chromatography/tandem mass spectrometry (LC-MS/MS). The multiple reaction monitoring (MRM) mode of precursor-product ion transitions for clindamycin (m/z=421.1/126.1) and ...
Influence of the nanostructure on the surface and bulk physical properties of materials
(Belgrade : Institute of Technical Sciences of SASA, 2010)
Fullerenes, nanotubes, quantum dots have been considered as effective sensitizers to modify both the spectral, optical, nonlinear optical features, dynamic and polarization characteristics, as well as mechanical properties ...
