XPS and contact angle study of cotton surface oxidation by catalytic bleaching
(Elsevier Science Bv, Amsterdam, 2007)
Surface chemistry and wetting properties of cotton fibres as affected by catalytic bleaching have been investigated. Two types of cotton fabric have been analysed: the regular and a model cotton fabric. In the regular - ...
Estimation of loading losses of petroleum products from tank trucks / Procena gubitaka isparavanja naftnih derivata prilikom pretakanja
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
In this paper was analyzed the quantity of loading losses, which are the primary source of evaporative emissions from tank cars and trucks. Loading losses occur as organic vapors in "empty" cargo tanks are displaced to the ...
Synthesis and settings behavior of alpha-TCP from calcium deficient hyroxyapatite obtained by hydrothermal method
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The aim of this work is the investigation of alpha-tricalcium-phosphate (alpha-TCP) formation from calcium-deficient hydroxyapatite (CDHAP), synthesized by hydrothermal method from CaCl2, EDTA, NaH2PO4 center dot 2H(2)O ...
Efficiency of oil removal from real wastewater with different sorbent materials
(Elsevier Science Bv, Amsterdam, 2007)
The aim of this paper was to investigate the efficiency of different sorbent materials for oil removal from wastewater. Two types of sorbents were investigated: organic (loose natural wool fibers (NWF) and recycled wool ...
Photocatalytic degradation of textile dye CI Basic Yellow 28 in water by UV-A/TiO2
(Association of the Chemical Engineers of Serbia, 2007)
CI Basic Yellow 28 (BY28), commonly used as a textile dye, could be photocatalytically degraded using TiO2 as catalyst and irradiated by UV-A lamp (300 W). However, UV and TiO2 showed no effect on the photodegradation when ...
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root
(Elsevier Science Bv, Amsterdam, 2007)
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root was investigated. Extractions from cultivar Arterner zuctung and two wild grown valerian subspecies were performed. The influence of extraction ...
Antimicrobial activity of the essential oil and different fractions of Juniperus communis L. and a comparison with some commercial antibiotics / Antimikrobna aktivnost etarskog ulja i različitih frakcija Juniperus communis L. i poređenje sa nekim komercijalnim antibioticima
(Serbian Chemical Society, Belgrade, 2007)
The essential oil of common juniper (Juniperus communis L., from the southern part of Serbia) and its fractions of different composition, as well as commercial antibiotics were used for testing their antimicrobial activity ...
Substituent and structural effects on the kinetics of the reaction of N-(substituted phenylmethylene)-m- and -p-aminobenzoic acids with diazodiphenylmethane / Efekti supstituenata i strukture na kinetiku reakcije N-(supstituisanih)-m- i -p-aminobenzoevih kiselina sa diazodifenilmetanom
(Serbian Chemical Society, Belgrade, 2007)
The rate constants for the reaction of twenty-two N-(substituted phenylmethylene)- m- and -p-aminobenzoic acids with diazodiphenylmethane were determined in absolute ethanol at 30 °C. The effects of substituents on the ...

(Ecomed Publishers, Landsberg, 2007)
Goal, Scope and Background. This paper is a part of the research work on 'Integrated treatment of industrial wastes towards prevention of regional water resources contamination INTREAT' the project. It addresses the ...
Theoretical assessment of calcium arsenates stability:Application in the treatment of arsenic contaminated waste
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca-5(AsO4)(3)OH have been proposed. These immobilization techniques ...
