A novel platinum-based nanocatalyst at a niobia-doped titania support for the hydrogen oxidation reaction
(Journal of the Serbian Chemical Society, 2011)
The kinetics of the hydrogen oxidation reaction (HOR) was studied at Pt nanoparticles supported on niobia-doped titania (Pt/N-T). The catalyst support, with the composition of 0.05NbO(2.5-delta)-0.995TiO(2) (0 LT delta LT ...
An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Taylor & Francis Ltd, Abingdon, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
Tailoring the supercapacitive performances of noble metal oxides, porous carbons and their composites / Rasvetljavanje superkondenzatorskih odlika oksida plemenitih metala, poroznih ugljeničnih materijala i njihovih kompozita
(Serbian Chemical Society, 2013)
Porous electrochemical supercapacitive materials, as an important type of new-generation energy storage devices, require detailed analysis and knowledge of their capacitive performances under different charging/discharging ...
Biodegradation of starch-graft-polystyrene and starch-graft-poly(methacrylic acid) copolymers in model river water / Biodegradacija kalemljenih kopolimera skroba i polistirena i skroba i poli(metakrilne kiseline) u rečnoj vodi
(Serbian Chemical Soc, Belgrade, 2013)
In this paper, a biodegradation study of grafted copolymers of cornstarch and polystyrene (PS) and cornstarch and poly(methacrylic acid) in model river water is described. These copolymers were obtained in the presence of ...
Characterization of glycidyl methacrylate based magnetic nanocomposites
(Savez hemijskih inženjera, Beograd, 2019)
Magnetic and non-magnetic macroporous crosslinked copolymers of glycidyl methacrylate and trimethylolpropane trimethacrylate were prepared by suspension copolymerization and functionalized with diethylenetriamine. The ...
Physical Properties of Sintered Alumina Doped with Different Oxides
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
Corundum (alpha-alumina) is a suiTab. material for usage in various industry fields owing to its chemical stability, electrical and mechanical features. It is known that properties of ceramics could be modified by addition ...
Influence of gamma radiation on measurement fast pulse voltages by Kerr electro-optic effect
(Radiation Effects and Defects in Solids, 2021)
In this paper, the possibility of measuring the electronic pulse from an electronic generator for plasma heating by electro-optical method is considered. The experiments are performed by applying the Kerr effect on an ...
An analysis of impact testing of high strength low-alloy steels used in ship construction
(Brodogradnja, 2021)
Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous. Brittle damages that occur on hull ...
The influence of thermodynamic parameters on alkaline activators of geopolymers and the structure of geopolymers
(Macedonian Journal of Chemistry and Chemical Engineering, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 degrees C for the process of ...
The shape of the polarization curve and diagnostic criteria for control of the metal electrodeposition process
(Serbian Chemical Society, 2016)
The simulated shapes of the polarization curves were correlated with the type of metal electrodeposition process control as a function of the ratio of the exchange current density to the limiting diffusion current density ...
