Electrochemical oxidation of carbon monoxide: From platinum single crystals to low temperature fuel cells catalysts - Part II: Electrooxidation of H2, CO and H2/CO mixtures on well characterized PtMo alloy / Elektrohemijska oksidacija ugljen-monoksida - od monokristala platine do katalizatora za niskotemperaturne gorivne galvanske spregove - II deo: Elektrohemijska oksidacija H2, CO I H2/CO smešama okarakterisanim PtMo legurama
(Serbian Chemical Society, Belgrade, 2003)
The oxidation of hydrogen and hydrogen–carbon monoxide mixture has been investigated on well-characterized metallurgically prepared platinum–molybdenum (PtMo) alloys. It was concluded that the optimum surface concentration ...
A new approach to the velocity field investigation in case of the entry flow in curved pipes with circular cross section
(Springer Wien, Wien, 2000)
In this paper an analysis of a laminar flow in a bend preceded by the straight section is presented. The flow is supposed to be unperturbed far upstream, while far downstream it becomes fully developed. In the vicinity of ...
Effect of substituents on the C-13 chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, Amsterdam, 1999)
C-13 chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C6H4-X, X having a wide range of substituent effects, have been determined in CDCl3 solution. Exceptionally good ...
Scaling of network segment dimensions in hyperelastic composites
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The change in elastomer tensile moduli, as formulated in the Gaussian statistical theory of rubber elasticity, with deformation, is considered both experimentally and theoretically. Gum elastomers of different structures ...
Indentation damage detection in thermoplastic composite laminates by using embedded optical fibers
(Journal of Advanced Materials, 2005)
In recent years, optical fibers have received attention as sensors for the purpose of in-service health monitoring in composite materials. Advantages of optical fiber sensors over conventional sensing methods are well-known ...
Release and diffusion studies of hydrogels based on itaconic acid
(8th Conference of the Yugoslav Materials Research Society, 2007)
Controlled release studies of drugs (theophylline (TH), fenethylline hydrochloride (FE) and gentamicin sulphate (GS)) from pH sensitive poly(2-hydroxyethyl methacrylate/itaconic acid) (P(HEMA/IA)) hydrogels obtained by ...
Saturated-liquid heat capacity of organic compounds: New empirical correlation model / Toplotni kapacitet zasićene tečnosti organskih jedinjenja - nov empirijski korelacioni model
(Serbian Chemical Society, Belgrade, 2004)
A new saturated-liquid heat capacity model is recommended. This model is tested and compared with the known polynomial and quasi-polynomial models on 39 sets with 1453 experimental heat capacity data. The obtained results ...
The role of the concentration profile of titanium oxide on the electrochemical behavior of RuO2-TiO2 coatings obtained by the sol-gel procedure / Uloga koncentracionog profila titan-oksida u elektrohemijskom ponašanju RuO2-TiO2 prevlaka dobijenih sol-gel postupkom
(Serbian Chemical Society, Belgrade, 2003)
In order to understand the role of TiO2 in the deactivation mechanism of an active RuO2–TiO2 coating, an additional TiO2 layer was introduced in the support coating interphase of regular Ti//[RuO2–TiO2 anode in one case ...
Microstructural characteristics of calcium hydroxyapatite/poly-L-lactide based composites
(Wiley, Hoboken, 1999)
Besides its high osteoinductive properties, hydroxyapatite (HAp) exhibits a relatively low mechanical strength. In order to improve the mechanical properties and reliability of HAp based composites, the addition of selected ...
