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, ...
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 ...
YUCOMAT 2008 features topics from designing materials on the atomic scale by nanotechnology to advanced high-tech applications

Mechanochemistry of titanium oxides
(Belgrade : Association of the Chemical Engineers of Serbia, 2009)
Mechanochemistry represents an alternative route in synthesis of nanomaterials. Mechanochemical routes are attractive because of their simplicity, flexibility, and ability to prepare materials by solid state reactions at ...
Ultrasonic de-agglomeration of barium titanate powder
(Ultrasonics Sonochemistry, 2008)
BaTiO3 (BT) powder, with average particle size of 1.4 mu m, was synthesized by solid-state reaction. A high-intensity ultrasound irradiation (ultrasonication) was used to de-agglomerate micro-sized powder to nano-sized ...
Far infrared properties of iron doped single crystal PbTe
(Măgurele : National Institute of Research and Development for Optoelectronics, 2008)
Far infrared reflectivity spectra of single crystal PbTe samples doped with 0.2 at% Fe were measured in the temperature range between 10 K and 300 K. These spectra show very sharp and narrow dips below 120 cm-1. The ...
Ultrasound synthesis of poly-dl-lactide-co-glycolide/hydroxyapatite core-shell nano-spheres
(8th World Biomaterials Congress 2008, WBC 2008; Amsterdam; Netherlands; 28 May 2008 - 1 June 2008, 2008)
Forming of titanium titnate
Lately a great attention is spared development of materials, possessing high stable dielectric properties. Among such materials a considerable place is occupied by titanates of metal series, including titanate of magnesium. ...
Isothermal sintering of BZT ceramics
Starting mixtures of BaCO3 •ZnO and Ti02 were mechanically activated for 0,5, 10,20.40 and 80 minutes in a planetary ball mill. The powders obtained were sintered isothermally to temperatures between 1000 and 1300 °C. The ...
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 ...
