Specific Properties of Polyester Fabrics Functionalized by RF Plasma and Colloidal TiO2 Nanoparticles
(Department of Materials, Textiles and Chemical Engineering, 2009)
This study was aimed to examine the possibility of using RF plasma at low pressure for the surface activation of polyester fabrics in order to improve the binding efficiency of colloidal TiO2 nanoparticles. Colloidal TiO2 ...
Mechanochemical synthesis and electrical conductivity of nanocrystalline δ-Bi2O3 stabilized by HfO2 and ZrO2
(Belgrade : Serbian Chemical Society, 2009)
A powder mixture of α-Bi2O3 and HfO2, in the molar ratio 2:3, was mechanochemically treated in a planetary ball mill under air, using zirconium oxide vials and balls as the milling medium. After 50 h of milling, the ...
Stability of Metal-Oxide Varistor Characteristics in Exploitation Conditions
(Acta Physica Polonica A, 2009)
Wide-spread use of metal-oxide varistors for non-linearity over-voltage protection results in a variety of possible working conditions. It is therefore essential to have a thorough insight into their reliability in various ...
Damage Level Estimate of API J55 Steel for Welded Seam Casing Pipes
(Strojarstvo, 2009)
The subject of this paper is investigation of the damage level of API J55 steel, used for manufacturing casing pipes by high frequency (HF) contact welding. The analysed pipe was withdrawn after about 70 000 hours of service ...
SmartMetals: a new method for metal identification based on fuzzy logic
(John Wiley & Sons Ltd, Chichester, 2009)
This paper presents a method of searching, identifying and cross-referencing metal alloys based on their chemical composition and/or mechanical properties, typically obtained by analysis and tests. The method uses a general ...
Primary and secondary dendrite spacing of Ni-based superalloy single crystals
(Serbian Chemical Society, 2009)
Ni-based superalloy single crystals were grown by different methods (gradient method and Bridgman technique with spontaneous nucleation and with seed). In all crystal growth experiments using the Bridgman technique, the ...
Reinvestigation of Sr2 [Cu(OH)6]
(International Union of Crystallography, 2009)
During an investigation of the SrO-CuO-P2O5-H 2O system, single crystals of distrontium hexa-hydroxido-cuprate(II), Sr2 [Cu(OH) 6], were obtained by the hydro-thermal method. The blue prismatic crystals of Sr2 [Cu(OH) 6] ...
The recycling of high magnesium aluminum alloys estimation of the most reliable procedure
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Aluminum is one of the most recyclable materials. Namely, the properties of aluminum are not affected by the recycling and reuse, thus enable that high value of the metal is maintained after reprocessing. The re-smelting ...
Possibility of triticale degradation using ultrasound / Mogućnost primene ultrazvuka za razgradnju tritikalea
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2009)
Influence of ultrasound on triticale was investigated. Triticale is a cereal characterized with high yields per hectare and its ability to grow on marginal lands. It's most frequently used as animal feed supplement or in ...
The influence of residual stresses on welded joints and other inhomogeneous materials with cracks / Uticaj zaostalih napona na ponašanje zavarenih spojeva i drugih nehomogenih materijala sa prslinama
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2009)
Residual stresses in many structural components are often produced during the fabrication or bonding processes, due to the cooling from elevated temperatures. Examples for such behavior are: welded and soldered joints, ...
