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 ...
Sulphation of CaO-based sorbent modified in CO2 looping cycles
(Proceedings of the 20th International Conference on Fluidized Bed Combustion, 2009)
CaO-based looping cycles for CO2 capture at high temperatures are based on cyclical carbonation of CaO and regeneration of CaCO3. The main limitation of natural sorbents is the loss of carrying capacity with increasing ...
Linear free energy relationships of the 1H and 13C NMR chemical shifts in 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)pyridones
(Elsevier, 2009)
Linear free energy relationships (LFER) were applied to the 1H and 13C NMR chemical shifts in 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)pyridones. The correlation analysis for the substituent-induced chemical shifts ...
EPR spin-trapping and spin-probing spectroscopy in assessing antioxidant properties: Example on extracts of catkin, leaves, and spiny burs of castanea sativa
(Food Biophysics, 2009)
Electron paramagnetic resonance (EPR) spin-trapping and spin-probing techniques were applied to determine antioxidant activity of extracts of catkin, leaves, and spiny burs of Castanea sativa against physiologically relevant ...
Structural and textural properties of Al,Fe-pillared clay catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Metal oxide pillared interlayered clays (PILCs) represent a new class of materials that have found a wide range of potential applications including catalytic oxidative degradation of organic pollutants in water. Al,Fe-pillared ...
AFM and SEM-EDS examination of highly dispersed heteropolyacids supported on MCM 41 and SBA 15 mesoporous materials
(Natl Inst Optoelectronics, Bucharest-Magurele, 2009)
Heteropolyacids (HPAS) H(3)PMo(12)O(40) (HPM) and H(4)PVMo(11)O(40) (HPVM) supported on mesoporous pure-silica and Al, Fe modified molecular sieve MCM-41 and SBA-15 have been prepared and characterized by atomic force ...
Synthesis of mesoporous nanocrystalline titania powders by nonhydrolitic sol-gel method
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
Mesoporous titania with well-crystallized anatase phase was synthesized by nonhydrolytic sol-gel process combined with solvothermal treatment. Titanium-isopropoxide, titanium-tetrachloride, and carbon-tetrachloride were ...
A mass transfer heterogeneous in systems by the adsorption method
(Association of the Chemical Engineers of Serbia, 2009)
A mass transfer coefficient between: A liquid and single sphere and a liquid And a column wall in packed and fluidized beds of a spherical inert Particle have been studied experimentally using the adsorption method. The ...
Characterization of recombinant antibodies for detection of TNT and its derivatives
(Versita, 2009)
Diverse recombinant immunoreagents specific for TNT–derivatives were tested in different assay forms in order to analyze their specificity and sensitivity. Performance of immunoassays was based on TNP–protein conjugates ...
Chemical composition of essential oils of Thymus and mentha species and their antifungal activities
(MDPI, 2009)
The potential antifungal effects of Thymus vulgaris L., Thymus tosevii L., Mentha spicata L., and Mentha piperita L. (Labiatae) essential oils and their components against 17 micromycetal food poisoning, plant, animal and ...
