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 ...
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, ...
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 impact of isatin derivatives on antibiotic production by Streptomyces hygroscopicus CH-7
(Association of Chemical Engineers of Serbia, 2016)
The effect of isatin derivatives as a nitrogen source on antibiotic (hexaene H-85 and azalomycine B) production by Streptomyces hygroscopicus CH-7 was studied. Isatin-3-hydrazone, 5-chloroisatin-3-hydrazone, isatin-3-tos ...
Electrochemical supercapacitors: Operation, components and materials
(Association of Chemical Engineers of Serbia, 2018)
Supercapacitors are the best choice when there is a need to deliver high power to the consumer or to store energy. Hybrid supercapacitors with their beneficial characteristics can somewhat overcome the basic lack of ...
Polysaccharides of higher fungi: biological role, structure and antioxidative activity
(Association of Chemical Engineers of Serbia, 2014)
The fungal polysaccharides attract a lot of attention due to their multiple challenging biological properties, such as: anti-tumor, anti-viral, anticomplementary, anticoagulant, hypolipidemic, immunomodulatory and ...
Modified bentonite as adsorbent and catalyst for purification of wastewaters containing dyes / Modifikovani bentonit kao adsorbent i katalizator za prečišćavanje otpadnih voda koje sadrže boje
(Assoc Chemists & Chemical Engineers Of Serbia, Belgrade, 2010)
Modification and characterization of bentonite from location Bogovina, Serbia was performed in order to obtain material applicable in wastewater purification. The LT 75μm bentonite fraction was used in organobentonite ...
