A microwave approach to the synthesis of certain 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones
(Srpsko hemijsko društvo, Beograd, 2014)
A study of the synthesis of 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones from ethyl 2-cyano-3-(substituted phenyl) acrylates and acetophenone is presented. The 2-pyridones were obtained using conventional as well ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (hsla) steel on low cycle fatigue
(Croatian Metallurgical Soc, Zagreb, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
The role of knowledge economy in solving unemployment problem / Uloga ekonomije znanja u rešavanju problema nezaposlenosti
(Društvo ekonomista Beograda, Beograd, 2014)
Knowledge economy means development based on production, distribution and usage of knowledge. Knowledge is main economic source and starter of modern economies. Knowledge in innovations and new technologies enable the ...
Low cycle fatigue of weldments produced of a high strength low alloyed steel
(Elsevier Science Bv, Amsterdam, 2014)
A quenched and tempered high strength low alloy steel NIONIKRAL 70 for producing welded pressure vessels, where high resistance to fatigue crack propagation and high tolerance of damage are of high importance, has been ...
Examining the Effects of the Destroying Ammunition, Mines and Explosive Devices on the Presence of Heavy Metals in Soil of Open Detonation Pit; Part 2: Determination of Heavy Metal Fractions
(Springer International Publishing Ag, Cham, 2018)
As a result of the destruction of ammunition, mines, and explosive devices by the method of open detonation, the increased concentration of heavy metals is often recorded in the soil of military polygons, which is a serious ...
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 ...
Dissipation of pirimiphos-methyl during wheat fermentation by Lactobacillus plantarum
(Wiley, Hoboken, 2013)
In this study, the dissipation of pirimiphos-methyl during wheat fermentation by Lactobacillus plantarum was investigated. Sample preparation for GC/MS detection of pirimiphos-methyl residues from fermented wheat substrate ...
The influence of thin benzoate-doped polyaniline coatings on corrosion protection of mild steel in different environments
(Elsevier Science Sa, Lausanne, 2013)
The corrosion process of mild steel in the presence of benzoate-doped polyaniline coatings exposed to different environments (3% NaCl, atmosphere, and the Sahara sand) has been investigated. This system was also tested for ...
Periodically operated CSTRs with simultaneous modulation of feed concentration and flow-rate- Nonlinear frequency response approach
(10th European Congress of Chemical Engineering (ECCE 10), Nice, France, 2015)
Possible improvements of chemical reactor performance through periodic modulation of one or more inputs have been investigated for several decades. In our previous investigations we have introduced the nonlinear frequency ...
Simultaneous enhancement of natural sunlightand artificial UV-driven photocatalytic activity of a mechanically activated ZnO/SnO2 composite
(Royal Soc Chemistry, Cambridge, 2017)
Mechanical milling of commercial ZnO and SnO2 was used to produce a ZnO/SnO2 composite with a high density of surface defects; in particular, zinc interstitials (Zni) and oxygen vacancies (VO). To determine the impact of ...
