Dynamic mechanical properties of aramid fabrics impregnated with carbon nanotube/poly (vinyl butyral)/ethanol solution
(Association of Metallurgical Engineers of Serbia, 2013)
In this study six samples of polyurethane/p-aramid multiaxial fabric forms (Colon fabrics) were coated with 10 wt.% poly (vinyl butyral) (PVB)/ethanol solution with the addition of multiwalled carbon nanotubes (MWCNT). The ...
Conceptual design for treatment of mining and metallurgical wastewaters which contains arsenic and antimony
(Association of Metallurgical Engineers of Serbia, 2012)
This paper presents a preliminary design for treatment of mining and metallurgical wastewaters (MMW) from the basin of antimony 'Zajača', which contains high concentrations of arsenic and antimony. MMW have been investigated ...
The effect of calcinated hydroxyapatite and magnesium doped hydroxyapatite as fillers on the mechanical properties of a model bisgma/tegdma dental composite initially and after aging
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This study aimed to investigate the possibility of modifying model BisGMA/TEGDMA dental composite by substituting 10 wt. % of conventional glass fillers with bioactive fillers based on calcinated nanosized hydroxyapatite ...
Bisphenol a removal from aqueous solution using fine alpha-fe2o3 particles
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Iron(III) oxide particles (alpha-Fe2O3) were obtained from ferrous chloride (FeCl3 center dot 6H(2)O) precursor using ammonium hydroxide as a precipitating agent and particles were calcined at 700 degrees C for 4 h. ...
Optimizing the thermal gradient and the pulling speed in a thermoplastic pultrusion process of pet/e glass fibers using finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2018)
A thermoplastic pultrusion process was examined using commercial fiber roving of PET/E glass, to determine the optimum pulling speed and optimal zonal temperatures. Finite element analysis predicted heat transfer through ...
Nanotubular oxide layers formed on the ti-based implants surfaces-application and possible damages: a review
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Implant surface properties define the interaction of the implant with the surrounding tissue. To obtained advanced biological, mechanical and physical properties, metallic implants are often exposed to different kinds of ...
Numerical simulation of temperature field in the vertical bridgman method crystal growth
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The mathematical model for heat transfer during the Bridgeman crystal growth, using the finite element method and the obtained result are presented. Some modifications to the method were introduced in order to incorporate ...
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 ...
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 ...
