Characterization of nanoporous carbon fibrous materials obtained by chemical activation of plane tree seed under ultrasonic irradiation
(Elsevier, 2014)
An ultrasonic irradiation was applied for the impregnation by chemical agents in the chemical activation process of new type of active carbon precursor. Plane tree seed, due to the unique fibrous structure and low cost is ...
RF MEMS and NEMS Components and Adsorption-Desorption Induced Phase Noise
(Institute of Electrical and Electronics Engineers Inc., 2014)
Radio frequency micro- and nanoelectromechanical systems (RF MEMS and RF NEMS) and technologies have a great potential to overcome the constraints of conventional IC technologies in realization of fully integrated transceivers ...
Biomimetic synthesis and properties of cellular SiC
(Elsevier Sci Ltd, Oxford, 2014)
Biomorphous beta-SiC ceramics were produced from several species of wood such as ash, wild cherry, black alder, Persian walnut, sessile oak and European hornbeam. The wood was pyrolysed, impregnated with tetraethyl ...
Insight into the Effect of Sn on CO and Formic Acid Oxidation at PtSn Catalysts
(American Chemical Society (ACS), 2014)
The role of Sn on the catalytic activity for CO and formic acid oxidation is studied by comparing the activities of differently treated PtSn/C and Pt/C catalysts. The catalysts are prepared by a microwave-assisted polyol ...
Non-isothermal reduction of silica-supported nickel catalyst precursors in hydrogen atmosphere: a kinetic study and statistical interpretation
(Springer, New York, 2014)
A series of silica-supported nickel catalyst precursors was synthesized with different SiO2/Ni mole ratios (0.20, 0.80 and 1.15). Non-isothermal reduction of Ni catalyst precursors was investigated by temperature-programmed ...
A kinetic study of quicklime-catalyzed sunflower oil methanolysis
(Inst Chemical Engineers, Rugby, 2014)
The quicklime-catalyzed sunflower oil methanolysis was studied at mild reaction conditions. Quicklime (calcined at 550 degrees C for 4h) in amounts of 1.0, 2.5, 5.0 and 10.0% (based on the oil weight) and different molar ...
Treatment of waste sulfuric acid copper electrolyte / Tretman otpadnog sumporno-kiselog elektrolita bakra
(Institut za rudarstvo i metalurgiju Bor, 2014)
The aim of this paper was to investigate the possibility of using the copper anodes with high nickel content for electrolytic treatment of waste sulfuric acid copper electrolyte. Nickel content in each anode was about 10 ...
Platinum(II) complexes with R(2)edda ligands (R = Me, Et, n-Pr; edda = ethylenediamine-N,N '-diacetate): Synthesis and characterization
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Three novel complexes of platinum(II) with R(2)edda bidentate ligands [PtCl2(R(2)edda)] (R = Me, Et, n-Pr; edda = ethylenediamine-N,N'-diacetate; 1-3), are synthesized and characterized by IR and NMR spectroscopy and ...
Photodegradation of Neonicotinoid Active Ingredients and Their Commercial Formulations in Water by Different Advanced Oxidation Processes
(Springer, Dordrecht, 2014)
This contribution is concerned with the comparison of the efficiency of the removal of four pure neonicotinoid active ingredients (AIs) and their commercial formulations (CFs) from aqueous solutions by using different ...
Lagergren Kinetic Model and Multianalyte Detection by Plasmonic Sensors
(Institute of Electrical and Electronics Engineers Inc., 2014)
This work is dedicated to modeling of adsorption processes in plasmonic sensors. We give a generalization of the Lagergren first order reaction kinetic model to the situations where adsorption takes place in multianalyte ...
