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 ...
Attachment of MEM piezoresistive silicon pressure sensor dies using different adhesives / Montaža čipova MEM silicijumskih piezorezistivnih senzora pritiska primenom različitih adheziva
(Association of Chemical Engineers of Serbia, 2011)
This paper gives comparison and discussion of adhesives used for attachment of silicon piezoresistive pressure sensor dies. Special attention is paid to low pressure sensor dies because of their extreme sensitivity on ...
Investigation of the morphology and surface properties of crosslinked poly(urethane-ester-siloxane)s / Ispitivanje morfologije i površinskih svojstava umreženih poli(uretan-estar-siloksana)
(Association of Chemical Engineers of Serbia, 2012)
Two series of crosslinked poly(urethane-ester-siloxane)s were synthesized from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS- -EO), 4,4'-methylenediphenyl diisocyanate and Boltorn® hyperbranched ...
Oxidation of hydroxide ions at platinum-modified zeolite electrode / Izvod oksidacija hidroksilnih jona na zeolitu modifikovanom platinom
(Association of Chemical Engineers of Serbia, 2012)
NaX zeolite was modified by platinum via impregnation/thermal decomposition technique, using Pt(II)-acetyl acetonate in acetone as an impregnating solution. The samples were characterized by scanning electron microscopy ...
Whether integrating refining and petrochemical business can provide opportunities for development of petrochemical industry in Serbia / Da li integrisanje rafinerijskog i petrohemijskog biznisa pruža mogućnost za razvoj petrohemijske industrije u Srbiji
(Serbia : Association of Chemists and Chemical Engineers of Serbia, 2016)
Since the beginning of 90s of last century both the petroleum industry and petrochemical industry have operated in difficult circumstances. In particularly, margins of petroleum and petrochemical industry were exacerbated ...
Removal of ethylene oxide from waste gases by absorption / Uklanjanje etilen-oksida iz otpadnih gasova postupkom apsorpcije
(Association of Chemical Engineers of Serbia, 2011)
Ethylene oxide (EtO) is an organic compound, which is used as a starting material in the production of polymers and as sterilizing agent for thermolabile materials. Although ethylene oxide is not common as an organic ...
