Impact testing with controlled energy of multiaxial aramid fabrics with various types of reinforcement / Ispitivanje udarima kontrolisane energije multiaksijalnih aramidnih lamina sa različitim tipovima ojačanja
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The physical and mechanical properties of the six samples of polyurethane/p-aramid multiaxial fabric forms (Kolon fabrics) were analyzed by high speed impact tester. The samples were impregnated with 10 wt.% poly (vinyl ...
Synthesis and characterization of the surface modified titanium dioxide/epoxy nanocomposites / Sinteza i karakterizacija nanokompozita na bazi površinski modifikovanih nanočestica titan-dioksida i epoksidne smole
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2015)
TiO2 nanoparticles, obtained by acid catalyzed hydrolysis of titanium isopropoxide, were surface modified by three gallic acid esters with different hydrophobic part length: octyl, decyl and lauryl gallate, and then used ...
Novel membrane-supported hydrogel for removal of heavy metals
(Elsevier Sci Ltd, Oxford, 2015)
Polyethersulfone membranes with integrated negatively-charged hydrogel of crosslinked poly (acrylamido-2-methylpropane sulfonic acid) were prepared by a combination of a liquid phase inversion process with photopolymerization ...
Antibacterial activity of copper-containing clinoptilolite/PVC composites toward clinical isolate of Acinetobacter baumannii
(Srpsko hemijsko društvo, Beograd, 2015)
The multidrug-resistant bacteria Acinetobacter baumannii cause serious hospital infections. Commercial poly(vinyl chloride) (PVC) used for endotracheal tubes was modified in order to obtain a composite with an antibacterial ...
The use in grass production of clinoptilolite as an ammonia adsorbent and a nitrogen carrier
(Srpsko hemijsko društvo, Beograd, 2015)
Clinoptilolite-rich tuff (NZ) from the Zlatokop deposit (Vranjska Banja, Serbia) was studied as a nitrogen carrier for grass production. The mechanism of binding ammonium cations present in aqueous solutions by NZ was ...
The Corrosion Behavior of an Ag43Cu37Zn20 Alloy in the Natural Seawaters
(Japan Inst Metals, Sendai, 2015)
We investigated the effects of natural seawater on the corrosion of an Ag43Cu37Zn20 alloy. The alloy was a commercial brazing filler alloy of composition (BS1845:1984 Ag5) and belongs to the class of Cd-free silver brazing ...
A genetic base of utilisation of maize grain as a valuable renewable raw material for bioethanol production
(Društvo genetičara Srbije, Beograd, 2015)
Maize (Zea mays L.) is one of the most important cereal crops, and as such, one of the most significant naturally renewable carbohydrate raw materials for the production of energy and multitude of different products. Many ...
Poly(methyl methacrylate) denture base materials modified with ditetrahydrofurfuryl itaconate: Significant applicative properties
(Srpsko hemijsko društvo, Beograd, 2015)
The aim of this work was to examine the possibility of modification of commercial denture base materials with itaconic acid esters, in order to obtain materials with lower toxicity and higher biocompatibility. Despite their ...
Bioindicators as a tool for environmental pollution analysis / Bioindikatori kao sredstvo za analizu zagađenosti životne sredine
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2015)
The interest in using bioindicators as monitoring tools to assess environmental pollution with toxic metals continually increasing. Heavy metals arise from natural sources and human activities, and once released in the ...
The improved photooxidation stability of the SILAR deposited copper sulfide on polypyrrole
(Elsevier Science Sa, Lausanne, 2015)
The copper sulfide is successfully deposited onto electrochemically formed polypyrrole, by successive ion-adsorption and reaction (SILAR) processes. The photoelectrochemical behavior of the polypyrrole, copper sulfide and ...
