Encapsulation of resveratrol in spherical particles of food grade hydrogels / Inkapsulacija resveratrola u sferične čestice na bazi hidrogelova dozvoljenih za upotrebu u hrani
(Institute for Food Technology, Novi Sad, 2017)
The paper reports about the preparation and characterization of hydrogel particles containing liposomes loaded with resveratrol as an active compound. The materials used for preparation of the particles were chosen to be ...
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 ...
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 ...
Tensile strength properties of hybrid magnetic composite materials / Zatezna čvrstoća hibridnih magnetnih kompozitnih materijala
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The Nd-Fe-B-barium ferrite hybrid composite materials with epoxy matrix presented in this paper cover maximum energy product from 1 to 13 MGOe. Mixture of magnetic particles is responsible for high magnetic quality, while ...
LT - contradiction matrix / LT - matrica kontradiktornosti
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2021)
Altschuller's Contradiction Matrix and Bartini-Kuznetsov's LT - Table represent two different tools for solving inventive problems based on the same dialectical principle. It starts from the premise that there are ...
Inventive level as a basis for the assessment of scientific contribution of inventors / Inventivni nivo pronalaska kao osnov za procenu naučnog doprinosa pronalazača
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
The history of invention reveals that the most important inventions were derived from experiments by which their authors contributed to the discovery of previously unknown natural phenomena. So the question arises as to ...
Ethanol Thymus serpyllum extracts: Evaluation of extraction conditions via total polyphenol content and radical scavenging activity
(Institute for Medicinal Plants Research "Dr. Josif Pancic", 2019)
The aim of the present study was the optimization of the extraction conditions (particle size, solid-to-solvent ratio, extraction time and procedure) via total polyphenol content and radical scavenging activity, using wild ...
Synthesis of novel wo3/zrsio4 catalysts for dehalogenation of halogenated hydrocarbons
(Savez inženjera metalurgije Srbije, Beograd, 2019)
This research aimed to develop a novel catalyst based on WO3/ZrSiO4 system for halogenated hydrocarbons processing. The production method of this catalyst involved extrusion and as such was simplified compared to thermo-chemical ...
The influence of Mg and Mn content on abnormal grain growth in AA5182 type alloys
(Savez inženjera metalurgije Srbije, Beograd, 2019)
The occurrence of abnormal grain growth (AGG) in AA5182 alloy during annealing imposes severe restrictions on processing parameters and deteriorates mechanical properties. In this work, we investigated the effect of chemical ...
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 ...
