Comparisons of formic acid oxidation at supported Pt catalyst and at low-index Pt single crystal electrodes in sulfuric acid solution / Poređenje oksidacije mravlje kiseline na PT katalizatoru na nosaču i na niskoindeksnim PT monokristalima u sumpornoj kiselini
(Serbian Chemical Society, 2003)
The oxidation of formic acid was studied at supported Pt catalyst (47.5 wt%. Pt) and a low-index single crystal electrodes in sulfuric acid. The supported Pt catalyst was characterized by the TEM and HRTEM techniques. The ...
Preparation and characterization of two types of covalently immobilized amyloglucosidase / Dobijanje i karakterizacija dva tipa imobilizovane amiloglukozidaze
(Serbian Chemical Soc, Belgrade, 2005)
Amyloglucosidase from A. niger was covalently immobilized onto poly( GMA-co-EGDMA) by the glutaraldehyde and periodate method. The immobilization of amyloglucosidase after periodate oxidation gave a preparate with the ...
Chemical modification of β-lactoglobulin by quinines / Hemijske modifikacije β-laktoglobulina hinonima
(Serbian Chemical Society, 2003)
The avarone/avarol quinone/hydroquinone couple, as well as their derivatives show considerable antitumor activity. In this work, covalent modifications of β-lactoglobulin, isolated from cow milk, by avarone, its model ...
The kinetics and mechanism of methanol oxidation on Pt and PtRu catalysts in alkaline and acid media / Kinetika i mehanizam oksidacije metanola na Pt i PtRu katalizatorima u alkalnoj i kiseloj sredini
(Serbian Chemical Society, 2007)
The kinetic of methanol electrochemical oxidation for a series of platinum and platinum-ruthenium catalysts was investigated. A correlation between the beginning of OHad adsorption and methanol oxidation was demonstrated ...
Electroreduction of cefetamet on mercury, platinum and gold electrodes / Elektroredukcija cefetameta na elektrodama od žive, platine i zlata
(Serbian Chemical Society, 2000)
The electroreduction of cefetamet (CEF) using gold and platinum electrodes has been investigated in slightly alkaline medium (pH 8.40) where adsorption, previously observed at mercury electrode, was pronounced. This ...
Prediction of the particle circulation rate in a draft tube spouted bed suspension dryer / Predviđanje cirkulacije čestica u sušioniku za suspenzije sa modifikovanim fontanskim slojem
(Serbian Chemical Society, 2006)
A model for predicting the particle circulation rate in a draft tube spouted bed dryer with inert particles is proposed and verified. The calculation algorithm requires three input values: the gas velocity in the draft ...
Carbon monoxide oxidation on bimetallic Ru/Au(111) surfaces / Оксидација CO на биметалним Ru/Au(111) површинама
(Belgrade : Serbian Chemical Society, 2001)
The electrochemical deposition of Ru on Au(111) was performed in 0.5 M H2SO4 + 10-4 M RuCl3. The obtained bimetallic Ru/Au(111) surfaces were characterised by cyclic voltammetry and in situ STM in 0.5 M H2SO4. The Ru deposit ...
On peroxide antimalarials / O peroksidnim antimalaricima
(Serbian Chemical Society, 2007)
Several dicyclohexylidene tetraoxanes were prepared in order to gain a further insight into structure-activity relationship of this kind of antimalarials. The tetraoxanes 2-5, obtained as a cis/trans mixture, showed ...
The effects of a magnetic field on the morphologies of nickel and copper deposits: The concept of 'effective overpotential' / Uticaj primenjenih magnetnih polja na morfologije taloga nikla i bakra - koncept 'efektivne prenapetosti'
(Serbian Chemical Society, 2007)
The morphologies of nickel and copper deposits obtained without applied magnetic fields, and with both parallel and perpendicular applied magnetic fields were examined by the scanning electron microscopy (SEM) technique. ...
Oxidation of dibenzothiophene as a model substrate for the removal of organic sulphur from fossil fuels by iron(III) ions generated from pyrite by Acidithiobacillus ferrooxidans / Oksidacija dibenzotiofena kao model-supstrata za izdvajanje organskog sumpora iz fosilnih goriva dejstvom gvožđe(III)-jona generisanog iz pirita pomoću Acidithiobacillus ferrooxidans
(Serbian Chemical Society, 2007)
Within this paper a new idea for the removal of organically bonded sulphur from fossil fuels is discussed. Dibenzothiophene (DBT) was used as a model compound of organicmolecules containing sulphur. This form of ...
