Synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalysed by amino acids / Sinteza 4,6-dimetil-3-cijano-2-piridona katalizovana aminokiselinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In this work the synthesis of 4,6-dimethyl-3-cyano-2-pyridone catalyzed by amino acids was studied. In the first part of the work, the optimization was carried out by varying the initial concentration of glycine, the molar ...
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) ...
Examination of the effectiveness of filtering half masks protection at various flow rates of aerosol contaminants / Ispitivanje efikasnosti zaštite filtrirajućih polumaski pri različitim protocima aerosolnih kontaminanata
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The possibility of air contamination by biological agents, by natural or artificial way, requires the improvement and use of different means for respiratory protection. The paper presents comparative filtration efficiency ...
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 ...
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 ...
Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. ...
Analysis of the effects of butt welded joints on a carrying capacity of a structure tank / Analiza uticaja sučeono zavarenih spojeva na nosivost konstrukcije rezervoara
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In the present paper, after calculation using the Finite Element Method (FEM), stress distribution on the model of a part of the pressure-tank mantle without welded joints (WJ), with transversal WJ, longitudinal WJ and ...
Behaviour of nionikral-70 in low-cycle fatigue
(Society for Structural Integrity and Life, Institute for Material Testing, 2017)
Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) ...
LT - Contradiction Matrix
(Fme Transactions, 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 ...
The tribological performance of hardfaced/thermal sprayed coatings for increasing the wear resistance of ventilation mill working parts
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2015)
During the coal pulverizing, the working parts of the ventilation mill are being worn by the sand particles. For this reason, the working parts are usually protected with materials resistant to wear (hardfaced/thermal ...
