Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel / Analiza parametara otpornosti na lom metodom konačnih elemenata, kod stacionarnih polueliptičnih prslina u čeliku povišene čvrstoće
(Society for Structural Integrity and Life, Institute for Material Testing, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
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 ...
Sorption of cadmium ions from saline waters onto Fe(III)-zeolite / Sorpcija jona kadmijuma iz slanih voda na Fe(III)-zeolitu
(Association of Chemical Engineers of Serbia, 2015)
The sorption of Cd2+ from natural seawater, artificial seawater, distilled water and NaCl solution of the same ionic strength as the seawater onto zeolite modified by iron(III) oxide (Fe(III)-zeolite) was investigated. The ...
Adsorption of Candida rugosa lipase onto alumina: effect of surface charge
(Serbian Chemical Society, 2015)
The impact of the surface charge of alumina supports on the adsorption of Candida rugosa lipase was investigated in terms of the zeta potentials of the adsorption partners. The lipase adhered onto alumina with similar ...
The use of different alumina fillers for improvement of the mechanical properties of hybrid PMMA composites
(Elsevier Sci Ltd, Oxford, 2015)
Alumina fillers having different morphologies were used for reinforcement of PMMA-based composite materials. The employed fillers had the same chemical composition but morphologically were spherical nanoparticles, whiskers ...
Manganese electrodeposition from urea-rich electrolyte
(Soc Chemists Technologists Madeconia, Skopje, 2015)
Pure manganese coatings were prepared on the steel (AISI 4340) electrode by a non-conventional electrodeposition method, in the presence of 8 mol dm(-3) of urea as a plating additive. The influence of urea on the ...
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 ...
Chemical Binding of Chitosan and Chitosan Nanoparticles onto Oxidized Cellulose
(Sage Publications Ltd, London, 2015)
The aim of this study was to analyze binding of chitosan and chitosan nanoparticles onto cellulose via oxidized cellulose. The ability of chitosan and chitosan nanoparticles to be adsorbed onto surfaces was determined by ...
Graphene Based Biomedical Composite Coatings Produced by Electrophoretic Deposition on Titanium
(Inst Higher Education Acad Sci, Alkmaty, 2015)
The biocomposite hydroxyapatite/graphene (HAP/Gr) and silver/hydroxyapatite/graphene (Ag/ HAP/Gr) coatings were electrodeposited on titanium substrate using the electrophoretic deposition (EPD) technique to produce bioactive ...
