NMR analysis of (1S, 1aR, 6aR)-2’, 3’, 6, 6a-tetrahydrospiro cycloprop a indene-1(1aH), 1’- 1H indene / NMR analiza (1S,1aR,6aR)-2’,3’,6,6a-tetrahidro-spiro[cikloprop[a]inden-1(1ah),1’-[ 1h]indena]
(Serbian Chemical Society, Belgrade, 2005)
The aldol condensation product of 1H-indan-1-one, (2E)-2-(2,3-dihydro-1H-in den-1-ylidene)-2,3-dihydro-1H-inden-1-one, subjected to Huang–Minlon reduction conditions was shown, via 1D and 2D NMR analysis, to be a mixture ...
Artificial neural network prediction of quantitative structure - retention relationships of polycyclic aromatic hydocarbons in gas chromatography
(Srpsko hemijsko društvo, Beograd, 2005)
A feed-forward artificial neural network (ANN) model was used to link molecular structures (boiling points, connectivity indices and molecular weights) and retention indices of polycyclic aromatic hydrocarbons (PAHs) in ...
Hydrothermal synthesis and structure of a new layered zincophosphate intercalated with 3-methylaminopropylamine cations / Hidrotermalna sinteza i struktura jednog novog slojevitog cinkofosfata interkaliranog sa 3-metilaminopropilamin-katjonom
(Serbian Chemical Society, Belgrade, 2005)
A novel layered zincophosphate (ZnPO–MPA) was prepared by hydrothermal crystallization using 3-methylaminopropylamine (MPA) as a structure-directing agent. The structure consists of macroanion [Zn2P3O8(OH)3]2- layers which ...
Low energy impact damage detection in laminar termoplastic composite materials by means of embedded optical fibers
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The possibility of applying optical fibers as sensors for investigation of real time low energy impact damage in laminar thermoplastic composite materials has been studied. For that purpose intensity based optical fibers ...
Properties of dispersion-hardened copper made by internal oxidation of prealloyed copper powder containing 2.5wt. % Al
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
Prealloyed copper powder containing 2.5wt. %Al was processed in a planetary ball mill to evaluate matrix hardening due to formation of Al2O3 particles in situ by internal oxidation. After milling, the powders were heat ...
Chain conformational statistics and mechanical properties of elastomer blends
(Amer Chemical Soc, Washington, 2005)
Design of mechanical properties, especially the relation between tensile and dynamic moduli in terms of chain conformational statistics is considered. Data on new elastomer blends with gradient properties, able for mixing ...
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 ...
Low-temperature plasma modification of wool
(Tekstil, 2005)
Low-temperature plasma treatment causes modification of specific wool properties (felting shrinkage, wettability, dyeability, printability, pilling) as a result of interaction between active plasma particles and fibre ...
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 ...
