Failures of Brass Condenser Tubes / Lomovi kondenzatorskih cevi od mesinga
(Belgrade Society for Structural Integrity and Life; IMS Institute, 2016)
Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and ...
Measurement of Permittivity of Solid and Liquid Dielectrics in Coaxial Chambers
(Belgrade : National Society for Microwave Technique, Technologies and Systems and Serbia and Montenegro IEEE MTT-S Chapter, 2016)
We present two coaxial chambers for measurements of the complex permittivity of solid and liquid samples, in a frequency range that is in the transition between lower frequencies, here parallel-plate capacitor ...
Selective anticancer activity of hydroxyapatite/chitosan-poly(D,L)-lactide-co-glycolide particles loaded with an androstane-based cancer inhibitor
(Colloids and Surfaces B: Biointerfaces, 2016)
In an earlier study we demonstrated that hydroxyapatite nanoparticles coated with chitosan-poly(d,l)-lactide-co-glycolide (HAp/Ch-PLGA) target lungs following their intravenous injection into mice. In this study we utilize ...
Scanning electron microscopy analysis of changes of hydroxiapatite/poly-l-lactide with different molecular weight of PLLA after intraperitoneal implantation
(Acta Veterinaria, 2016)
Implantation of a biomaterial is one of the important trends in solving the problem of bone tissue loss. Calcium hydroxiapatite (HAp), as the most representative bone component is a serious candidate for such implantations. ...
Biblioteke naučnoistraživačkih instituta i ustanova: zakonodavni okvir i praksa
(Čitalište, 2016)
U Srbiji postoji više od 70 akreditovanih naučnih instituta, ustanova i centara izuzetnih vrednosti, sa bibliotekama čiji knjižni fondovi često premašuju fondove fakultetskih biblioteka, sa bibliotekarima i knjižničarima ...
Uklanjanje uranil-jona iz rastvora kiselo tretiranim zeolitima
(Zaštita materijala, 2016)
Cilj ovog rada je prikaz mogućnosti primene prirodnog i modifikovanog zeolitskog minerala kao adsorbenta i materijala za sanaciju voda kontaminiranih uranijum jonom. Modifikovani uzorci zeolita dobijeni su tretiranjem ...
Arsenic removal by magnetite-loaded amino modified nano/microcellulose adsorbents: Effect of functionalization and media size
(Elsevier, 2016)
Comparative adsorption study related to benefits of parent media size, i.e. microfibrillated cellulose (MC) versus nanocellulose (NC) support, for the preparation of magnetite (MG) based high performance adsorbent for ...
Zirconium dioxide nanopowders with incorporated Si4+ions asefficient photocatalyst for degradation of trichlorophenol usingsimulated solar light
(Elsevier, 2016)
We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporatedSi4+ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powderswere annealed at 600◦C ...
Oxygen reduction on SILAR deposited iron oxide onto graphite felt electrode
(Elsevier, 2016)
The potential characteristics of graphite felt electrodes, modified by iron oxide, for oxygen reduction are evaluated. Modification is carried out by Successive Ion Layer Adsorption and Reaction (SILAR) method, using a ...
Reaction kinetics of mechanically activated cordierite-based ceramics studied via DTA
(Springer, 2016)
Since cordierite, 2MgO·2Al2O3·5SiO2 (MAS), is a very useful high-temperature ceramic material, it is important to decrease its sintering temperature. In order to accelerate the process of sintering, 5.00 mass% MoO3 was ...
