The influence of acid treatment on the composition of bentonite
(USA : The Clay Minerals Society, 2006)
Bentonite from the 'Bogovina' coal mine in Serbia, was characterized. The influence of acid treatment on its composition, as well as mathematical descriptions of this influence are reported. The purpose of this work was ...
Mass transfer in vertical liquid-solids flow of coarse particles
(Powder Technology, 2009)
Wall-to-bed mass transfer in the hydraulic transport of spherical glass particles was studied. The experiments were performed by transporting spherical glass particles 1.20, 1.94 and 2.98 mm in diameter with water in a ...
Mechanism of complex formation between [AuCl4]- and l-methionine
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The kinetics of the reaction between the tetrachloroaurate(III) ion and l-methionine (l-Met) (0.1 M HClO4, pH 1.0-2.5) have been studied spectrophotometrically using a stopped-flow technique at different temperatures. ...
Erratum: Organocatalyzed Cyclizations of pi-allylpalladium complexes: A new method for the construction of five- and six-membered rings (vol 9, pg 5064, 2007)
(American Chemical Society (ACS), 2007)
Page 5064. Two references pertinent to the described work have been omitted in ref 13: For the first example of combining organocatalysis and transition metal catalysis, see: (e) Jellerichs, B. G.; Kong, J.-R.; Krische, ...
Titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides: a new method for the synthesis of gamma-butanolides
(Oxford : Pergamon-Elsevier Science Ltd, 2002)
A new method for the synthesis of gamma-butanolides is described. The titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides, followed by acidic work-up, affords the corresponding butyrolactones in ...
Origin of oils in the Velebit oil-gas field, SE Pannonian Basin, Serbia - Source rocks characterization based on biological marker distributions
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Twenty five crude oil samples from Velebit oil-gas field (SE Pannonian Basin, Serbia) were investigated in order to define the depositional environment, lithology, thermal maturity and depth of burial of the corresponding ...
Petrological, organic geochemical and geochemical characteristics of coal from the Soko mine, Serbia
(Elsevier, 2008)
A petrological, organic geochemical and geochemical study was performed on coal samples from the Soko Mine, Soko Banja basin, Serbia. Ten coal and two carbonaceous clay samples were collected from fresh, working faces in ...
Activity of a PtBi alloy in the electrochemical oxidation of formic acid
(Elsevier, 2006)
Formic acid oxidation in acid solution was examined on a PtBi alloy characterized by X-ray photoelectron spectroscopy. Three chemical states of Bi, i.e., PtBi or Bi(0), Bi2O3 and BiO(OH) were found. Electrochemical ...
Stoichiometric Network Analysis and Associated Dimensionless Kinetic Equations. Application to a Model of the Bray-Liebhafsky Reaction
(American Chemical Society (ACS), 2008)
The stoichiometric network analysis (SNA) introduced by B. L. Clarke is applied to a simplified model of the complex oscillating Bray-Liebhafsky reaction under batch conditions, which was not examined by this method earlier. ...
Structural modification of fullerene thin films by highly charged iron ions
(Springer, 2007)
In this paper, the results of structural modification of fullerene thin films bombarded by highly charged iron ions (Fe6+) are presented. The properties of as-deposited and irradiated fullerene thin films have been ...
