TIMS and MALDI TOF of endohedral Li-n"C-70 (n=1-3) metallofullerenes
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
Using the ion implantation technique (introducing negatively charged fullerene into a low temperature lithium plasma column by a strong axial magnetic field) endohedral fullerenes Li"C-70, Li-2"C-70 and Li-3"C-70 were ...
Prevention and control of dimethylamine vapors emission: Herbicide production plant
(Association of the Chemical Engineers of Serbia, 2008)
The widely used herbicide, dimethylamine salt of 2,4-dichlorophenoxy acetic acid (2,4-D-DMA), is usually prepared by mixing a dimethylamine (DMA) aqueous solution with a solid 2,4-dichlorophenoxy acetic acid (2,4-D). The ...
Lipase catalyzed synthesis of flavor esters in non-aqueous media: Optimization of the yield of pentyl 2-methylpropanoate by statistical analysis / Sinteza mirisnih estara katalizovana lipazama u nevodenoj sredini - optimizacija prinosa pentil-2-metilpropanoata statističkom analizom
(Serbian Chemical Society, Belgrade, 2008)
In this study, the synthesis of pentyl 2-methylpropanoate employing a commercial lipase from Candida rugosa was investigated, the emphasis being placed on analyzing the effects of various process conditions on the yield ...
Double-layer bioactive glass coatings obtained by pulsed laser deposition
(Trans Tech Publications Ltd, Durnten-Zurich, 2008)
Pulsed laser deposition was used to obtain functionally graded bioactive glass coatings on titanium substrates. An UV KrF* (lambda=248 nm, tau gt 7 ns) excimer laser was used for the multi-pulse irradiation of the targets. ...
A correlation for heat of vaporization of pure compounds
(Korean Institute Chemical Engineers, Seoul, 2008)
Twenty-seven selected equations were tested on 162 compounds with 1958 calorimetric data for their abilities to reflect the temperature influence on the heat of vaporization of pure compounds. A new equation is recommended ...
Nonlinear FR-ZLC method for investigation of adsorption equilibrium and kinetics
(Springer, New York, 2008)
A new method for investigation of adsorption equilibrium and kinetics, named Nonlinear Frequency Response-Zero Length Column (NFR-ZLC) method, is introduced. It combines the advantages of the Nonlinear FR method (the ...
Thermal shock damage characterization of high temperature ceramics by non destructive test methods
(University of Chemistry and Technology, Prague, 2008)
In the present work a mixture of commercially available spinel, quartz (SiO2) and alumina (Al2O3) corresponding to cordierite stoichiometry was used as starting material for obtaining cordierite/SiC composite ceramics with ...
Cavitation damage of the medium carbon steel: Implementation of image analysis
(Elsevier Science Bv, Amsterdam, 2008)
Cavitation damage of the medium carbon steel was performed using the modified vibratory cavitation test set up. Erosion rates were measured by analytical method. The morphology of damage under cavitation action was determined ...
The effects of hemicelluloses and lignin removal on water uptake behavior of hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
This study investigated the individual influences of hemicelluloses and lignin removal on the water uptake behavior of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin were obtained by ...
Electrochemical and sorption characteristics of metacryloxypropyltrimethoxysilane coatings / Elektrohemijske i sorpcione karakteristike prevlaka metakriloksipropiltrimetoksisilana
(Engineering Society for Corrosion, Belgrade, Serbia, 2008)
The aim of this work was to investigate the influence of deposition parameters (silane solution concentration, deposition time, curing time) on electrochemical and sorption characteristics of metacryloxypropyltrimethoxysilane ...
