The influence of the shape and size of the AL2O3 particles on the flexural properties of the PMMA composite modified by the addition of dimethyl itaconate / Uticaj oblika i veličine čestica AL2O3 na savojna svojstva PMMA kompozita modifikovanog dodatkom dimetil itakonata
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Dental materials have specific requirements regarding behavior in exploitation conditions. Poly (methyl methacrylate) (PMMA) is one of the most commonly used prosthetic materials. It is of interest to improve the mechanical ...
Simulation of blast furnace operation during the substitution of coke and pulverized coal with granulated waste plastic / Simulacija rada visoke peći prilikom supstitucije koksa i sprašenog uglja granulisanom otpadnom plastikom
(Savez inženjera i tehničara Srbije, Beograd, 2014)
The possibility of using the waste plastic as reducing agent in blast furnace for obtaining pig iron is in focus for the past couple year. The simulation of blast furnace process in BFC software has been performed in order ...
Effect of tracers molecular weight on the release process from alginate microbeads / Uticaj molekulske mase trejserskih indikatora na kontrolisano otpuštanje iz alginatnih mikročestica
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The aim of this paper is to obtain microbeads of natural polymers such as alginate and chitosan. These microbeads were used as potential carriers for the active ingredients so that in this study the diffusion of various ...
The application of the zeolyte powder for the construction of the dense composite membranes for the carbon-dioxide separation / Primena zeolitnih prahova za izradu kompozitnih polimernih membrana za separaciju ugljen-dioksida
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The main task of the work is to construct the polymeric membrane that could be used for the waste gases treatment. For this purpose, membrane must have high permeability for the carbon dioxide and low permeability of the ...
Infuence of solvent on the stability of electrospinning of PMMA nanofibers / Uticaj rastvarača na stabilnost procesa elektropredenja polimernih nanovlakana
(Savez inženjera i tehničara Srbije, Beograd, 2014)
In this paper the process of electrospinning of PMMA nanofibers was investigated. The influence of process parameters (type of solvent, solution concentration, flow rate, distance of needle and collector) on the nanofibers ...
Impregnation of cellulose acetate films with carvacrol using supercritical carbon ioxide / Impregnacija filmova acetata celuloze karvakrolom pomoću natkritičnog ugljenik(IV)-oksida
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Cellulose acetate films were impregnated with carvacrol using supercritical carbon dioxide. The supercritical impregnation process, conducted in a static regime at pressure of 21 MPa and temperature of 50°C, was optimized ...
