Geopolymerization of low-grade bauxite
(Institute of Metals and Technology, 2014)
In terms of quality, bauxite ore can be classified as high- or low-grade ore. High-grade bauxite ores are used for alumina extraction using the Bayer process, while low-grade bauxite ores have a limited application. In ...
The influence of service solutions on the longitudinal and circumferential tensile properties of glass-polyester composite pipes
(Springer, New York, 2011)
In numerous cases, metals and alloys traditionally used as structural materials in the process equipment can now be successfully replaced by nonmetallic composite materials. We study the influence of service solutions on ...
Corrosion resistance of high pressure torsion obtained commercially pure titanium in acidic solution
(University of Osijek, Tech Fac, Slavonski Brod, 2017)
The enhancement of commercially pure titanium (cpTi) mechanical properties, which is required for its medical application, can be achieved by grain refinement obtained by severe plastic deformation. In addition to mechanical ...
Influence of the type of electrolyte on the morphological and crystallographic characteristics of lead powder particles / Uticaj tipa elektrolita na morfološke i kristalografske karakteristike praškastih čestica olova
(Serbian Chemical Society, 2013)
Lead electrodeposition processes from basic (nitrate) and complex (acetate) electrolytes were mutually compared by scanning electron microscopy and X-ray diffraction investigation of the produced powder particles. The shape ...
Integrity assessment of bucket wheel excavator welded structures by using the single selection method
(University of Osijek, Tech Fac, Slavonski Brod, 2013)
In order to reduce the testing costs for structural welded joints and production losses due to excavator standstill, a new method for integrity and reliability assessment of welded joints during exploitation of bucket wheel ...
Gamma Radiation Absorption Characteristics of Concrete with Components of Different Type Materials
(Acta Physica Polonica A, 2010)
Nuclear facilities as nuclear power stations, nuclear research reactors, particle accelerators and linear accelerator in medical institution using concrete in building construction. The different type materials of the ...
Plant waste materials from restaurants as the adsorbents for dyes / Iskorišćenje sirovog otpada iz restorana za adsorpciju boja
(Association of Chemical Engineers of Serbia, 2015)
This paper has demonstrated the valorization of inexpensive and readily available restaurant waste containing most consumed food and beverage residues as adsorbents for methylene blue dye. Coffee, tea, lettuce and citrus ...
Identification of phases formed by Cu and Ni in Al-Si piston alloys
(Associazione Italiana di Metallurgia, 2014)
This paper presents the results of identifying and analyzing the phases present in the microstructure of 4 aluminum piston alloys with different chemical composition. Optical microscopy and scanning electron microscopy ...
Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
In vitro biocompatibility assessment of Co-Cr-Mo dental cast alloy
(Srpsko hemijsko društvo, Beograd, 2015)
Metallic materials, such as Co-Cr-Mo alloys, are exposed to aggressive conditions in the oral cavity that represents an ideal environment for metallic ion release and biodegradation. The metallic ions released from dental ...
