Failures of Brass Condenser Tubes / Lomovi kondenzatorskih cevi od mesinga
(Institut za ispitivanje materijala, Beograd, 2016)
Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and ...
Production of rubber plasticizers based on waste PET: Techno-economical aspect / Sinteza plastifikatora iz otpadnog PET-a za primenu u gumenim proizvodima - tehno-ekonomska analiza
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
Production of rubber plasticizers, based on waste poly(ethylene terephthalate) (PET), and economic effectiveness of developed technologies are presented and discussed. Waste PET glycolyzates, named diisononyl terephthalate(DINTP), ...
Alkyd nanocomposite coatings based on waste pet glicolyzates and modified silica nanoparticles / Alkid nanokompozitni premazi bazirani na otpadnim pet glikolizatima modifikovani nanočesticama silike
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Synthesis of high-performance alkyd resins (ARs) based on waste poly(ethylene terephthalate) (PET) glycolyzates is presented. PET glycolyzates were synthesized by catalytic depolymerization with trimethylolpropane (TMP) ...
Ni-pd/al(2)o(3) catalyst supported on reticulated ceramic foam for dry methane reforming
(Savez inženjera metalurgije Srbije, Beograd, 2015)
In the present study, Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation ...
Assessment of sampling and chemical analysis of waste printed circuit boards from weee: gold content determination
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Waste printed circuit boards (WPCBs) from discarded mobile phones and smartphones are considerably heterogeneous materials with a high gold content (approx. 490 grams per ton). The aim of our chemical analysis of samples ...
Failures of brass condenser tubes
(Society for Structural Integrity and Life, Institute for Material Testing, 2016)
Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and ...
Aramid composites impregnated with different reinforcement: Nanofibers, nanoparticles and nanotubes / Aramidni kompoziti impregnisani sa različitim ojačanjima - nanovlakna, nanočestice i nanocevi
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
In this study, the electrospun nanofibers, nanoparticles and nanotubes were used as reinforcement in order to improve mechanical properties of materials for ballistic protection. The samples of polyurethane/p-aramid ...
The influence of novel organic gold complex on photoresist layers of printed circuit boards
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this paper was to study the influence of organic gold complex based on mercaptotriazole on photoresist layers used in manufacturing of printed circuit boards (PCBs). Investigations were performed by immersion ...
Influence of the Fe(III): Modified clinoptilolite on phosphorus leaching from different soil types / Uticaj Fe(III)- modifikovanog klinoptilolita na izluživanje fosfora iz različitih vrsta zemljišta
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Influence of the iron(III)-modified clinoptilolite (FeCLI) on phosphorus leaching from two different Norwegian soil types (sand and clay loam soil) was studied using a column system at room temperature. FeCLI was used in ...
