Optimization of processing parameters for preparation of LaNiO3 thin films from the citrate precursors
(Elsevier Sci Ltd, Oxford, 2007)
Lanthanum nickel oxide (LaNiO3) is an electrically conductive ceramics, which has a potential use as electrode for ferroelectric thin films, multilayer actuators and many other electronic devices. In this work, LaNiO3 thin ...
Experimental and numerical evaluation of a steamline behaviour using local approach
(Croatian Metallurgical Society, 2007)
Results of the experimental and numerical comparative analysis of steamline pipes have been presented. New pipes and the pipes used for more than 117,000 hours at 540 degrees C under pressure of 42 bars have been simultaneously ...
Properties of aliphatic hyperbranched polyesters in dilute solutions
(Serbian Chemical Society, 2007)
The results of an investigation of the influence of the synthesis procedure, number of pseudo generations and degree of branching of hydroxy-functional aliphatic hyperbranched polyesters (AHBP) on the values of limiting ...
Numerical and analytical modeling of elastic-plastic fracture mechanics parameters
(8th Conference of the Yugoslav Materials Research Society, 2007)
Structural integrity and service reliability depend on the fracture resistance of a material. Cracks in the material are the locations of stress concentration, and elastic-plastic deformation can occur causing the development ...
A model for predicting fracture toughness in overaged 7000 alloy forgings
(Savez inženjera metalurgije Srbije, Beograd, 2007)
An attempt to develop a multiple micromechanism-based model for predicting plane-strain fracture toughness, KIc, of overaged 7000 alloy forgings has been made. The proposed model reveals the quantitative relations between ...
Sintering of Cu-Al2O3 nano-composite powders produced by a thermochemical route / Sinterovanje nano-kompozitnih prahova Cu-Al2O3 dobijenih termohemijskih postupkom
(Serbian Chemical Society, Belgrade, 2007)
This paper presents the synthesis of nano-composite Cu-Al2O3 powder by a thermochemical method and sintering, with a comparative analysis of the mechanical and electrical properties of the obtained solid samples. ...
A linear solvation energy relationship study for the reactivity of 2-substituted cyclohex-1-enecarboxylic and 2-substituted benzoic acids with diazodiphenylmethane in aprotic and protic solvents / Proučavanje reaktivnosti 2-supstituisanih cikloheks-1- -enkarboksilnih i 2-supstituisanih benzoevih kiselina u aprotičnim i protičnim rastvaračima pomoću linearne korelacije solvatacionih energija
(Serbian Chemical Society, Belgrade, 2007)
The rate constants for the reaction of 2-substituted cyclohex-1-enecarboxylic acids and the corresponding 2-substituted benzoic acids with diazodiphenylmethane were determined in various aprotic solvents at 30 ºC. In order ...
Numerical method for the prediction of bending properties of glass-epoxy composites / Primena numeričkog modela za predviđanje savojnih svojstava staklo-epoksi kompozitnog materijala
(Faculty of Technology, Novi Sad, 2007)
Mechanical properties of composite materials are conditioned by their structure and depend on the characteristics of structural components. In this paper is presented a numerical model by which the bending properties can ...
Analysis of the properties of a Cu-Al2-O3 sintered system based on ultra fine and nanocomposite powders
(International Institute for the Science of Sintering, Beograd, 2007)
In this paper synthesis of a composite based on Cu-Al2O3 by a thermo-chemical method is shown along with a comparative analysis of the properties of the obtained nanocomposite sintered samples, which are characterized by ...
High activity of Pt4Mo alloy for the electrochemical oxidation of formic acid
(Amer Chemical Soc, Washington, 2007)
Surface processes on Pt4Mo alloy well-defined by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were studied in acid solution by cyclic voltammetry. It was established that Mo in the alloy is much more ...
