Changes of HAp/PLLA biocomposites and tissue reaction after subcutaneous implantation
(Niš : University of Niš, 2003)
Experimental and clinical studies have shown that HAp granules and powder may be successfully applied in reconstruction of bone defects. Composite HAp/PLLA biomaterial embodies good characteristics of each of these ...
Analiza osetljivosti debeloslojnih NTC termistora na promene temperature i protoka vazduha
(Čačak : University of Kragujevac, Faculty of Technical Sciences, 2006)
NTC termistori na bazi Mn, Ni, Co i Fe oksida za potrebe debeloslojnih senzora pripadaju oblasti istraživačkog i primenjenog rada sa ciljem realizacije senzora prilagođenih po obliku, prenosu toplote i brzini odziva fizičkim ...
Kinetika elektrohemijske reakcije redukcije glukoze
(2004)
PhD defence presentation. The thesis "Kinetics of electrochemical reaction of glucose reduction" was defended at the University of Belgrade, Faculty of Technology and Metallurgy, in 2004.
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
Karakterizacija katodnih materijala LiMn2-xMxO4 (M=Mn, Cr, Zn) sintetisanih ultrazvučnom sprej pirolizom
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2004)
Metodom ultrazvučne sprej pirolize sintetisani su prahovi LiMn2O4, LiCr0.175Mn1.825O4 i LiZn0,082Mn1,918O4. Prahovi su dobijeni raspršivanjem vodenog rastvora nitrata odgovarajućih metala, ultrazvučnim raspšivačem frekvencije ...
Sinteza, karakterizacija i degradacija nanosfera poli(DL-laktid-ko-glikolida) koje sadrže askorbinsku kiselinu
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2007)
Askorbinska kiselina (vitamin C) je izuzetno važan i organizmu neophodan vitamin. Ima ulogu reduktanta slobodnih radikala čime smanjuje oštećenja nastala oksidativnim stresom koji je uzrok ili pratilac mnogih bolesti. U ...
Sonohemijska sinteza i karakterizacija hidroksiapatita i poli(d,l-laktid-ko-glikolid)/hidroksiapatit kompozita
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2008)
U radu predstavljenom u ovoj magistarskoj tezi ultrazvučna metoda je iskorišćena za sintezu hidroksiapatita (HAp), usitnjavanje dobijenih aglomerata ultrazvučnim poljem visokog intenziteta i njihovo oblaganje poli(d,l-la ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
(Elsevier, 2009)
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...
Photoacoustic characterization of natural mineral pyrite (FeS2)
(Springer, 2008)
A single p-type crystal of the mineral, pyrite (FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic (PA) amplitude and phase spectra were measured using a specially ...
Genotoxicity of the poly-D,L-lactide microparticles on the human lymphocytes
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Particles generated of biodegradable material are extensively investigated as carriers
for sustained drug delivery. Studies have been mainly focused on the monitoring of the drug
release and of the rate of the particle ...
