Optimization of integrated steel plant recycling: Fine-grain remains and by-products synergy
(Strojarstvo, 2011)
The recycling capabilities of the integrated steel plant (capacity 2 million tons/year), have been evaluated annually. The quantities of dusts, scales and sludge generated at the Steel Plant located in Smederevo, Serbia, ...
Swelling, Mechanical and Antimicrobial Studies of Ag/P(HEMA/IA)/PVP Semi-IPN Hybrid Hydrogels
(Polish Acad Sciences Inst Physics, Warsaw, 2011)
A simple and fast approach to the design and production of new hybrid polymeric biomaterials with silver particles is presented in this work. Silver/semi-interpenetrating network hybrid hydrogels (Ag/semi-IPNHHs) were ...
Optimization of Active Carbonaceous Material Obtained by Low Hydrothermal Carbonization of Plane Tree Seed with H3PO4
(Trans Tech Publications Ltd, Durnten-Zurich, 2017)
Activated carbons (ACs) were successfully prepared using plane tree seed (PTS) as a cheap and renewable raw material. The plane tree seeds were firstly treated combining magnetic (MM) and ultrasonic mixing (USM) during ...
Simplification of the synthesis of the reversible addition-fragmentation chain transfer agent 2-(2-cyanopropyl)-dithiobenzoate / Pojednostavljenje postupka sinteze raft agensa 2-(2-cijanopropil)-ditiobenzoata
(Serbian Chemical Society, Belgrade, 2010)
The general literature procedure for the preparation of the reversible addition-fragmentation chain transfer (RAFT) agent 2-(2-cyanopropyl)-dithiobenzoate (CPDB) was modified by omitting the recrystallisation of the ...
Modeling of strength degradation during water quench test of low cement high alumina castable
(University of Chemistry and Technology, Prague, 2010)
Low cement high alumina castable was synthesized, cured, and then sintered at 1100 degrees C for 3 hours. Water quench test was used as an experimental method for thermal stability testing. Image analysis program was applied ...
catena-Poly[[[(di-2-pyridylamine-kappa N-2(2),N-2 ')copper(II)]-mu-benzene-1,3-dicarboxylato-kappa O-3(1),O-1 ':O-3] monohydrate], a zigzag coordination polymer with strong pi-pi interactions
(Wiley-Blackwell, Hoboken, 2011)
The novel title coordination polymer, {[Cu(C8H4O4)-(C10H9N3)]center dot H2O}(n), synthesized by the slow-diffusion method, takes the form of one-dimensional zigzag chains built up of Cu-II cations linked by benzene-1,3-d ...
Diffusion of polyphenols from alginate, alginate/chitosan, and alginate/inulin particles
(Wiley, Hoboken, 2019)
Thymus serpyllum L (thyme) aqueous extract was encapsulated within three different types of particles. Thus, electrostatic extrusion was applied to obtain alginate, alginate/chitosan, and alginate/inulin particles with ...
New method for synthesis of N-alkyl and N,N-dialkyl-O-ethyl and O-isopropylthiocarbamates by oxidation of ammonium salt of xhantogenic acid / Novi postupak sinteze N-alkil- i N,N-dialkil-O-etil- i O-izopropiltiokarbamata oksidacijom aminskih soli ksantogene kiseline
(Association of Chemical Engineers of Serbia, 2010)
Syntheses of N-alkyl and N,N-dialkyl-O-ethyl and O-isopropyl thiocarbamates by oxidation of ammonium salts of ethyl- and isopropylxanthogenic acid in the presence of sodium hypochlorite and hydrogen peroxide were performed. ...
Influence of the way of synthesis of poly(methyl methacrylate) in the presence of surface modified TiO2 nanoparticles on the properties of obtained nanocomposites / Uticaj načina sinteze poli(metil metakrilata) u prisustvu površinski modifikovanih TiO2 nanočestica na svojstva dobijenih nanokompozita
(Association of Chemical Engineers of Serbia, 2010)
Incorporation of inorganic nanoparticles can significantly affect the properties of the polymer matrix. The properties of polymer nanocomposites depend on the type of incorporated nanoparticles, their size and shape, their ...
