Phenolic profile of some fruit wines and their antioxidant properties
(Association of Chemical Engineers of Serbia, 2016)
The composition and content of individual phenolic compounds in various fruit wines and overall antioxidant properties of these fruit wines were studied. Phenolic compounds were separated by reverse phase (RP) HPLC techniques, ...
Effect of tungsten carbide in carbon Pt catalyst support on electrochemical oxygen reduction in acid solution / Uticaj prisustva volfram-karbida u ugljeničnom nosaču Pt nanočestica na elektrohemijsku redukciju kiseonika u kiselom rastvoru
(Association of Chemical Engineers of Serbia, 2013)
Tungsten carbide was synthesized by calcination of carbon cryogel with embedded tungsten in a form of metatungstate. This material was used as a support for Pt nanoparticles. XRD pattern of W-C support indicated the presence ...
The qualitative determination of oseltamivir phosphate in Tamiflu® capsule by cyclic voltammetry / Kvalitativno određivanje oseltamivir-fosfata u Tamiflu® kapsulama pomoću ciklične voltametrije
(Association of Chemical Engineers of Serbia, 2011)
A gold electrode was used in the voltammetric determination of oseltamivir phosphate standard in 0.05 M NaHCO3. Oseltamivir phosphate as a standard and as a component of Tamiflu® capsule exhibited the identical cyclic ...
The influence of Schiff base inclusion complexes with beta-cyclodextrine on antibiotic production by Streptomyces hygroscopicus CH-7 / Uticaj kompleksa Šifovih baza sa beta-ciklodekstrinom na produkciju antibiotika pomoću Streptomyces hygroscopicus CH-7
(Association of Chemical Engineers of Serbia, 2015)
A media consisting of isatin-Schiff bases and its inclusion complexes with beta-cyclodextrine was developed to maximize the production of antibiotics Hexaene H-85 and azalomycine B by Streptomyces hygroscopicus CH-7. The ...
Synthesis and swelling behavior of polyurethane networks based on hyperbranched polymer / Sinteza i ispitivanje bubrenja umreženih poliuretana na bazi hiperrazgranatog polimera
(Association of Chemical Engineers of Serbia, 2011)
A series of six polyurethane (PU) networks was synthesized from Boltorn® hydroxy-functional hyperbranched polyester (HBP) of the second pseudo generation as a cross-linking agent, a,w-dihydroxy-(ethylene oxide-poly(dimet ...
Ecologically Friendly Chitosan-montmorillonite Bio-nanocomposite as Adsorbent for Textile Dyes from Aqueous Solutions
(International Institute for the Science of Sintering, Beograd, 2017)
The bio-nanocomposite of montmorillonite and natural biopolymer chitosan (C-MM) was synthesized. Intercalation of chitosan in form of monolayer into the interlamellar space of montmorillonite was confirmed by XRD and IR ...
Characteristics and catalytic behavior of supported NiMgAg/D catalysts in the partial hydrogenation of soybean oil
(Springer Netherlands, 2015)
Diatomite supported NiMgAg catalysts, NiMgAg/D, were prepared by the precipitation-deposition method followed by drying, reduction and passivation. The preparation of the catalysts was performed with different loading of ...
Printed Antenna Array with Flat-Top Radiation Pattern
