Surface composition and adsorption properties of activated carbon cloth
(Belgrade : Institute of Technical Sciences of SASA, 2003)
Surface properties of activated carbons have shown to play an important role in
adsorption process. The presence of various functional groups (such as phenolic, carbonyl,
carboxylic) on the carbon surface depends on the ...
New directions in hemp spinning / Novi pravci u predenju vlakna konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2003)
If hemp, besides flax the only textile fiber that Europe must not import, is ever to regain its lost ground in new circumstances of comfort and ecology, it must be through development of new products and new end uses. This ...
Electrochemical oxidation of methanol on Pt3Co bulk alloy / Elektrohemijska oksidacija metanola na leguri Pt3Co
(Serbian Chemical Society, Belgrade, 2003)
The electrochemical oxidation of methanol was investigated on a Pt3Co bulk alloy in acid solutions. Kinetic parameters such as transfer coefficient reaction orders with respect to methanol and H+ ions and energy of activation ...
Analysis of fatigue and crack growth in carbon-fiber epoxy matrix composite laminates
(Strength of Materials, 2003)
A study of high frequency fatigue in carbon-fiber reinforced composites has been undertaken. A comparison has been made between the fatigue behavior of crossply (0 / 90) and angleply (± 45) carbon/epoxy unnotched and notched ...
Characteristics of looms for production woven fabrics made of agro cellulose fibers / Karakteristike razboja za proizvodnju tkanina od agroceluloznih vlakana
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2003)
In this paper technical characteristics and possibilities of single phase and multiphase looms for production of woven fabrics made of agro cellulose fibers of some world lieder manufacturers of looms are described. In the ...
Noble metals binding on the macroporous poly(gma-co-egdma) modified with ethylenediamine
(Belgrade : Institute of Technical Sciences of SASA, 2003)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol
dimethacrylate) copolymer, poly(GME), was synthesized by radical suspension
copolymerization and modified with ethylenediamine, EDA. Useability of ...
An analysis of occurrence and beginning of stable crack growth in the low-alloyed steel for pressure vessels / Analiza nastanka i početka stabilnog rasta prsline u niskolegiranom čeliku za posude pod pritiskom
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2003)
Pressure vessels are often made of low-alloyed steel that should be characterized by proper values of strenght, toughness, formability and weldability. In this paper the crack initiation in low-alloyed ferritic steel (Rp0.2 ...
Selectivity in extraction of copper and indium with chelate extractants
(Skopje : Macedonian union of metallurgists, 2003)
Simultaneous extraction of copper and indium with chelate extractants (LIX84 and D2EHPA) was
described. Stechiometry of metal-organic complexes examined using the method of equimolar ratios resulted in
CuR2 and InR3 forms ...
