Removal of aqueous manganese using the natural zeolitic tuff from the Vranjska Banja deposit in Serbia
(Elsevier, Amsterdam, 2009)
The natural zeolite tuff from the Vranjska Banja deposit (Serbia) has been studied as sorbent for Mn(II) ions from aqueous solutions. The zeolite sample containing mainly clinoptilolite (more than 70%) removes Mn(II) ions ...
Sorption properties of TEMPO-oxidized natural and man-made cellulose fibers
(Elsevier Sci Ltd, Oxford, 2009)
Cotton and lyocell fibers were oxidized with sodium hypochlorite and catalytic amount of sodium bromide and 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO), under various conditions. Water-insoluble fractions, collected ...
Electrospray mass spectrometric studies of a potential antitumor drug and its analogous platinum(II) and platinum(IV) complexes with the ethylenediamine-N,N '-di-3-propanoato ligand and its dibutyl ester
(Springer Wien, Wien, 2009)
The electrospray mass spectrometric (ESI-MS) behavior of the complexes trans-dichloro(ethylenediamine-N, N'-di-3-propionato) platinum(IV), trans-dibromo(ethylenediamine-N, N'-di-3-propionato) platinum( IV), dichloro ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Elsevier, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm-3 HClO4, saturated with H2 containing 100 ppm CO, was examined with rotating disc ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Journal of Electroanalytical Chemistry, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Linking phylogenetic identities of bacteria to starch fermentation in an in vitro model of the large intestine by RNA-based stable isotope probing
(Wiley-Blackwell, Malden, 2009)
Carbohydrates, including starches, are an important energy source for humans, and are known for their interactions with the microbiota in the digestive tract. Largely, those interactions are thought to promote human health. ...
Kinetic study of the hydrogen oxidation reaction on sub-stoichiometric titanium oxide-supported platinum electrocatalyst in acid solution
(Elsevier, 2009)
The kinetics and mechanism of the hydrogen oxidation reaction were studied in 0.5 mol dm-3 HClO4 solution on an electrode based on titanium oxide with Magneli phase structure-supported platinum electrocatalyst applied on ...
Oxidative modifications of cellulose in the periodate system - Reduction and beta-elimination reactions
(Walter de Gruyter & Co, Berlin, 2009)
The conversion of cellulose to dialdehyde cellulose (DAC) by treatment with aqueous periodate was studied by the CCOA method, which is a combination of gel permeation chromatography and carbonyl-selective fluorescence ...
Kinetics of sunflower oil methanolysis catalyzed by calcium oxide
(Elsevier, 2009)
The methanolysis of sunflower oil was studied in the presence of CaO previously calcined at various temperatures and the optimal temperature for CaO calcination was determined. The sigmoidal process kinetics was explained ...
Mechanochemically induced amorphous/crystalline phase transition in the Bi4Ti3O12 compound
(Elsevier, 2009)
Concurrent milling of Bi4Ti3O12 was carried out in a planetary ball mill with hardened-steel 13 or 6 mm diameter balls with a goal to investigate how the system responds to the constrains imposed by milling. Milling intensity ...
