Thermal and Thermomechanical Properties of Organic-Inorganic Nanocomposites Prepared from Polyurethane Network and Mesoporous Silica Nanoparticles
(Serbian Ceramic Society, 2019)
Polyurethane (PU) networks based on poly(dimethylsiloxane) (PDMS) and hyperbranched polyester (HBP) possess unique properties such as chemical stability, good thermal behavior, good surface and mechanical properties, making ...
Primena lasera u arheologiji i metaparadigma nove muzeologije
(Zemun: Institute of Physics, University of Belgrade, 2010)
Uvođenje 3D laserskog skeniranja u oblast arheologije donelo je promene u brojnim aspektima heritološke paradigme, posebno u domenu dokumentacije. Mogućnost virtuelne spekulativne nadgradljivosti arheoloških lokaliteta, ...
Antimicrobial activities of two copper(Il) complexes with 4-(diethylamino)salicylaldehyde and a-diimine
(Belgrade : Serbian Chemical Society, 2018)
Two novel coppe(tr) complexes (Fig. 1) with 4-(diethylamino)salicylald.hyd. as ligand (HL) and o-diimine - 2,2'-bipyridine (bipy) or 1,lO-phenanthroline (phen) with potentially antimicrobial activity are described. Complex ...
Oscillatory reaction as novel method in distinguishing bentonites
(Serbian Ceramic Society, 2018)
In the chemical oscillatory reaction the concentrations of the reactants decrease and products increase in stepwise form, while the concentrations of intermediates oscillate with time. In this paper, the influence of ...

Investigation of thermal shock resistance in alumina based refractory castables
(Nova Science, 2019)
Refractory castables, like all ceramic materials, contain numerous structural defects in the form of flaws, pores, microcracks, and impurities. These materials are often used in conditions of exposure to sudden and cyclical ...
Corrosion of Cannon 75/27, model 1911. Déport, from the Collection of the Military Museum in Belgrade / Корозија топа 75/27, модел 1911. DEPORT из колекције Војног Музеја у Београду
(Faculty of Mechanical Engineering, Belgrade, 2012)
This paper analyzes the state of the French Cannon 75/27 model 1911.
Déport made of steel. The amount of non-corroded materials, the presence
of cracks and other defects in the cannon were determined by the
radiographic ...
