Molecular spectroscopy analysis of the substitution of bone tissue by HAp/PLLA composite biomaterial
(IOS Press, 2004)
Due to its pronounced osteoinductive properties, calcium hydroxyapatite (HAp) has been widely used in medicine. Bioresorptive poly-L-lactide (PLLA) as a polymer biomaterial has been also used extensively in medicine for ...
The kinetics of the electrochemical reduction of xylose on amalgamated zinc / Kinetika elektrohemijske redukcije ksiloze na amalgamu cinka
(Čačak : University of Kragujevac - Faculty of Agronomy, 2009)
During the electrolysis of an aqueous solution of xylose, two parallel reactions take place on the cathode i.e. the reduction of xylose to xylitol and hydrogen evolution. To favor the desired reaction of xylose reduction, ...
Korozioni aspekti nano-katalizatora na bazi plemenitih metala
(Beograd : Inženjersko društvo za koroziju, 2005)
U poslednjih deset godina došlo je do snažnog razvoja različitih tipova gorivnih spregova kao što su: spregovi sa čvrstim polimernim elektroltima visoko-temperaturni gorivni spregovi, spregovi sa čvrstim elektrolitima na ...
The synthesis - structure relationship in the ZnO-Cr2O3 system
(Belgrade : International Institute for the Science of Sintering, 2004)
In this work the development of the spinel phase in the ZnO-Cr2O3 system was discussed from the viewpoint of the synthesis-structure relationship. The nanostructure evolution in particles obtained either via solution-based ...
Ispitivanje sinterovane cink-kalaj-oksidne keramike fotoakustičnom spektroskopijom

Prahovi ZnO i SnO2 pomešani u molamom odnosu 2:1 mehanički su aktivi- rani u planetamim mlinu sa kuglama u intervalu od 10 do 160 minuta. Do- bijene smeše presovane su i izotermski sinterovane na 1300 °C, dva sata. Uzorci ...
Uticaj mehanohemijskog tretmana na strukturne promene u kompozitu hidroksiapatit/poli-l-laktid
(Tehnika - Novi materijali, 2004)
Promena strukture i osobina biokompozitnog materijala HAp/PLLA tokom mehanohemijskog tretmana predmet su analize u ovom radu. Smeša HAp/PLLA uparena je u vakuumu i zatim podvrgnuta suvom mlevenju u planetarnom mlinu do ...
Structure and characteristics of the hot pressed hydroxyapatite/poly-L-lactide composite
(Belgrade : International Institute for the Science of Sintering, 2002)
Hydroxyapatite/poly-L-lactide (HAp/PLL) composite biomaterial can be obtained by different processing methods. Three-dimensional blocks of HAp/PLLA composite biomaterial with mechanical characteristics close to the natural ...
