13C- and 1H-NMR substituent-induced chemical shifts in N(1)-(4-substituted phenyl)-3-cyano-4,6-dimethyl-2-pyridones / Supstituentima izazvana 13C- i 1H-NMR hemijska pomeranja N(1)-(4-supstituisani fenil)-3-cijano-4,6-dimetil-2-piridona
(Serbian Chemical Society, Belgrade, 2008)
The 13C- and 1H-NMR chemical shifts of thirteen N(1)-(4-substituted phenyl)-3-cyano-4,6-dimethyl-2-pyridones were measured in deuterated dimethyl sulfoxide (DMSO-d6). The correlation analysis for the substituent-induced ...
Alginate microbeads as potential support for cultivation of bone marrow stromal cells
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Alginate is currently being employed and explored for a broad range of biomedical and biotechnology applications, due to its biodegradability and simple procedure for cell immobilization. However, cell immobilization was ...
Substituent and solvent effects on the UV/vis absorption spectra of 3-N-alkyl-5-carboxy uracils
(Natl Inst Science Communication, New Delhi, 2003)
Absorption spectra of ten 3-N-alkyl-5-carboxy uracils are recorded in fourteen solvents in the range 200-400 nm. The absorption frequencies of carboxy carbonyl electronic transitions are correlated by dual substituent ...
Study of gold-platinum and platinum-gold surface modification and its influence on hydrogen evolution and oxygen reduction / Površinska modifikacija platine zlatom i zlata platinom i njen uticaj na reakcije izdvajanja vodonika i redukcije kiseonika
(Serbian Chemical Society, Belgrade, 2005)
Surface modification of the electrodes was conducted from sulfuric acid solutions containing the corresponding metal-chloride complexes using cyclic voltammeter. Comparing the charges of the hydrogen underpotential deposition ...
A new ecologically friendly process for the synthesis of selective flotation reagents
(Association of the Chemical Engineers of Serbia, 2009)
A new ecologically friendly synthesis of N-alkyl-O-ethylthioncarbamates from ethyl dixanthogenates, waste material from the xanthate production plant, and monoalkylamines has been performed in this work. Structure determination ...
Comparative study on biochemical activity of the intestinal isolates Lactobacillus sp. V3 and Bifidobacterium sp. A71 in different substrates / Uporedna ispitivanja biohemijske aktivnosti intestinalnih izolata Lactobacillus sp. V3 i Bifidobacterium sp. A71 u različitim supstratima
(Serbian Chemical Society, Belgrade, 2001)
The two intestinal isolates Lactobacillus sp. V3 and Bifidobacterium sp. A71 were selected for soymilk fermentation according to their acidification activity in soymilk. Beetroot juice and carrot juice were chosen for ...
Emulsion stability evaluation using fractal dimensions approach
(8th Conference of the Yugoslav Materials Research Society, 2007)
There are many developed strategies for evaluating emulsion stability, aimed at determining the life circle of emulsions. Most of them are based on rheological properties of emulsions. There are, however, very few based ...
Solvent effects on the structure-activity relationship of pharmacological active 3-substituted-5,5-diphenylhydantoins
(Springer/Plenum Publishers, New York, 2007)
Absorption spectra of eight 3-substituted-5,5-diphenylhydantoins have been recorded in fourteen solvents in the range 200-100 nm. The effect of solvent dipolarity/polarizability and solvent/solute hydrogen bonding interactions ...
Exchange between the stagnant and flowing zone in gas-flowing solids-fixed bed contactors / Razmena čestica između pokretne i nepokretne zone u kontaktorima gas-pokretna čvrsta faza-pakovan sloj
(Serbian Chemical Society, Belgrade, 2005)
In countercurrent gas - flowing solids - fixed bed contactors, a fraction of the flowing solids is in motion (dynamic holdup), while the other fraction is resting on the fixed bed elements. In this study it was experimentally ...
