The effect of the cross-linker content on the swelling properties of intelligent gels / Efekat sadržaja umreživača na svojstva bubrenja inteligentnih gelova
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2014)
This paper presents the procedure for the synthesis of hydrogels based on N-isopropylacrylamide (NIPAM) and 2-hydroxypropyl methacrylate (HPMet) using dioxan as a solvent. Hydrogels were obtained by radical polymerization ...
Removal of magnesium in spring water using the natural zeolite in a continuous flow system / Uklanjanje magnezijuma iz izvorske vode pomoću prirodnog zeolita u protočnom sistemu
(Association of Chemical Engineers of Serbia, 2014)
The aim of this work is an investigation of the possible application of Serbian natural zeolitic tuff ('Igroš Vidojević' deposit, Brus, Serbia) for improvement of the spring water quality. The concentration of magnesium ...
Dynamic temperature field in the ferromagnetic plate induced by moving high frequency inductor
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The subject of the paper is the temperature distribution in the thin metallic ferromagnetic plate influenced by moving linear high frequency induction heater. As a result of high frequency electromagnetic field, conducting ...
Solvent and Structure Effects on Electronic Absorption Spectra of the Isomeric Pyridinecarboxylic Acids
(Springer, New York, 2014)
Ultraviolet absorption spectra of three isomeric pyridinecarboxylic acids (picolinic, nicotinic, and isonicotinic acids) were measured in 18 various solvents, in the wavelength range from 200 to 400 nm. In order to analyze ...
Identification of low cycle fatigue parameters of high strength low-alloy (hsla) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Suitability of heat treatment for crack resistance of material in the connection part of heavy transporter for liquid slag
(Croatian Metallurgical Soc, Zagreb, 2014)
The post weld heat treatment (PWHT) was used to reduce the level of the residual stresses and increase of the crack resistance of the material in the connection part.The article presents the results of the residual stress ...
Thermal, morphological, and mechanical properties of ethyl vanillin immobilized in polyvinyl alcohol by electrospinning process
