Formation of Disperse Silver Deposits by the Electrodeposition Processes at High Overpotentials
(Esg, Belgrade, 2012)
In this study, electrodeposition of silver from nitrate solution at the high overpotentials was analyzed. Morphologies of silver deposits obtained at the different overpotentials and with the different electrodeposition ...
Intrinsic Distortion Path in the analysis of the Jahn-Teller effect
(Elsevier, 2010)
The multideterminental-DFT approach was performed in order to calculate the Jahn-Teller (JT) parameters for the JT active molecules. Within the harmonic approximation the JT distortion can be analysed as a linear combination ...
Polyphenolic compounds in seeds from some grape cultivars grown in Serbia / Polifenolna jedinjenja iz semenki osam sorti grožđa gajenih u Srbiji
(Serbian Chemical Soc, Belgrade, 2010)
Seed extracts from eight grape cultivars (Vitis vinifera) growing in Serbia were screened for their polyphenolic composition by means of HPLC/ /PDA/ESI/MS analysis. The study revealed 34 phenolic compounds belonging to the ...
Characterization of copper powder particles obtained by electrodeposition as function of different current densities
(Journal of Applied Electrochemistry, 2009)
Technological properties of powders depend on their granulometry and morphology. Very often one method is inadequate for characterization of powder particles. This article studied different methods intended for clear ...
A trapezoidal microstrip bandstop filter with efficient suppression of undesired stopbands
(National Institute of Optoelectronics, 2010)
A new bandstop filter implemented as a cascade of trapezoidally shaped cells is presented. The proposed bandstop filter suppresses many undesired stopbands at higher frequencies. The cell design is specified by two variables ...
Evaluation of saturated and aromatic hydrocarbons oil-oil maturity correlation parameters (SE Pannonian Basin, Serbia) / Евалуација матурационих параметара заснованих на засићеним и ароматичним угљоводоницима у корелацији нафта-нафта (југоисточни део панонског басена , Србија)
(Belgrade : Serbian Chemical Society, 2007)
Twenty three crude oils from the Serbian part of the Pannonian Basin (14 from the Vojvodina Province and 9 from the Drmno Depression) were investigated, aimed at an evaluation of oil-oil maturity correlation parameters ...
Application of reactive siloxane prepolymers for the synthesis of thermoplastic poly(ester-siloxane)s and poly(ester-ether-siloxane)s / Primena reaktivnih siloksanskih pretpolimera za sintezu poli(ester-siloksana) i poli(ester-etar-siloksana)
(Belgrade : Serbian Chemical Society, 2007)
Thermoplastic poly(ester-siloxane)s (TPES) and poly(ester-ether-siloxane)s, (TPEES), based on poly(butylene terephthalate) (PBT) as the hard segment and different siloxane-prepolymers as the soft segments, were prepared. ...
Preparation and modification of itaconic anhydride-methyl methacrylate copolymers / Синтеза и модификација кополимера анхидрида итаконске киселине и метил-метакрилата
(Belgrade : Serbian Chemical Society, 2007)
The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60°C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios ...
Electrochemical Oxidation of Methanol and Ethanol on Electrodeposited Pd and PdNi-Coated Electrodes
(Pleiades Publishing Inc, Moscow, 2017)
Electrodeposited PdNi and Pd samples were tested for methanol and ethanol oxidation reaction (MOR and EOR) in alkaline solution using cyclic voltammetry (CV) and chronoamperometric (CA) measurements. Among the CVs for the ...
Impact of carboxymethylcellulose on morphology and antibiotic production by Streptomyces hygroscopicus
(Current Microbiology, 2008)
A chemically defined media consisting of carboxymethylcellulose (CMC) was developed to maximize the production of antibiotics, hexaene H-85 and azalomycine, by Streptomyces hygroscopicus CH-7. The production of antibiotics ...
