Antimicrobial cotton fibers prepared by tempo-mediated oxidation and subsequent silver deposition
(Editura Acad Romane, Bucuresti, 2016)
In this paper, we merge the unique properties of cotton and silver in order to obtain antimicrobial cotton fibers. The sorption properties of cotton were improved by selective TEMPO-mediated oxidation, i.e. oxidation with ...
Nickel-based catalysts: Dependence of properties on nickel loading and modification with palladium
(Savez hemijskih inženjera, Beograd, 2016)
The aim of this study was comparative analysis of catalysts with 5 and 20 wt.% Ni loading, with and without Pd additive, and it included: determination of reduction degrees, investigation on microstructure by scanning ...
Synthesis, Structure and Properties of Nickel-Iron-Tungsten Alloy Electrodeposits PART II: Effect of Microstructure on Hardness, Electrical and Magnetic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2016)
Nanostructured nickel-iron-tungsten alloys were produced by electrodeposition from an ammoniacal citrate bath. The tungsten content of the alloy ranged from 0.8 wt.% to 11 wt.%, and the crystal grain size of the FCC phase ...
Walsh analysis - a convenient preprocessor for period detection in astronomy
(Astronomical Observatory Belgrade, 2016)
Walsh analysis is practically analogous to Fourier analysis, except that square wave is used instead of the sine one. It has one major advantage over Fourier - it can be performed much faster. This may seem of little ...
Multi-criteria analysis of synthesis methods for ni-based catalysts
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2016)
Catalysts based on the Ni/Al2O3 system are used in a variety of catalytic processes. Catalysts are commonly synthesized through thermochemical routes (impregnation, precipitation, coprecipitation and others). The authors ...
Micromechanical investigating of the critical parameter's influence on adhesive properties of porous EVA/PMMA polymer blends using finite element method
(Belgrade : Institute of Technical Sciences of SASA, 2016)
Galacto-oligosaccharide synthesis using chemically modified beta-galactosidase from Aspergillus oryzae immobilised onto macroporous amino resin
(Elsevier Sci Ltd, Oxford, 2016)
The goal of this study was to establish an efficient immobilisation protocol for beta-galactosidase from Aspergillus oryzae onto the polystyrenic macroporous resin Purolite (R) A-109 for better utilisation of its ...
Pouzdanost piezometara na brani »Bajina Bašta« na osnovu podataka osmatranja
(Institut za istraživanja i projektovanja u privrediUniverzitet u Beogradu, Mašinski fakultetDruštvo održavalaca tehničkih sistema, 2016)
Razvojem i modernizacijom oskultacionih instrumenata postiže se veća tačnost i ponovljivost merenja, ali i automatsko očitavanje i akvizicija mernih podataka, a samim tim i praćenje stanja objekata u realnom vremenu. Senzori ...
Novel β-galactosidase nanobiocatalyst systems for application in the synthesis of bioactive galactosides
(Royal Society of Chemistry, 2016)
In this study, unmodified, amino modified and cyanuric chloride functionalized amino modified nonporous fumed nano-silica particles (FNS, AFNS and CCAFNS, respectively) were used for the development of efficient nanobiocatalysts ...
Analysis of the tool plunge in friction stir welding comparison of aluminum alloys 2024 t3 and 2024 t351
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
Temperature, plastic strain and heat generation during the plunge stage of the friction stir welding of high-strength aluminum alloys 2024 T3 and 2024 T351 are considered in this work. The plunging of the tool into the ...
