The effect of the particle shape and structure on the flowability of electrolytic copper powder I: Modeling of a representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha I - modelovanje reprezentativne čestice praha
(Serbian Chemical Society, 2003)
One of the most important properties of copper powder is its flow ability which depends on the shape and the structure of the powder particles. A procedure for the determination of a representative powder particle permitting ...
FTIR study on N-H·hydrogen bonding: N-alkylpropanamides - aromatic donor system / FTIC spektroskopsko izučavanje N-H·vodoničneveze - sistemi N-alkilpropanamid - aromatični donor
(Serbian Chemical Society, Belgrade, 2003)
This paper reports the results of an FTIR study in the region of the fundamental NH stretching vibration for N-methyl, N-isopropyl, N-tert-butyl and N-1,2,2-trimethylpropanamide – aromatic hydrocarbon systems. In addition ...
The current efficiency during the cathodic period of reversing current in copper powder deposition and the overall current efficiency / Iskorišćenje struje za vreme katodnog perioda reversne struje pri taloženju bakarnog praha i ukupno iskorišćenje struje
(Serbian Chemical Society, 2003)
The current efficiency during the cathodic period of reversing current in copper powder deposition was determined by measuring the quantity of hydrogen evolved. The diagrams from which the instantaneous and average current ...
The critical apparent density for the free flow of copper powder / Kritična nasipna masa za tečenje praha bakra
(Serbian Chemical Society, 2003)
A method for the determination of the critical apparent density, which permits the free flow of electrodeposited copper powder is discussed. It was found that powders the apparent density of which were larger than 2.3 g/cm3 ...
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 ...
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 ...
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 ...
Inverse gas chromatography study of synthetic hydroxyapatite surface by hexane adsorption at finite surface coverage
(Belgrade : Institute of Technical Sciences of SASA, 2003)
The sorption of both organic and inorganic substances on synthetic hydroxyapatite
(HAP) was studied intensively in the last decade, due to HAP application in diverse fields of
science and technology. In this paper, HAP ...
Physico-chemical properties of polymeric and composite bioresorbable barrier membranes
(Belgrade : Institute of Technical Sciences of SASA, 2003)
Bioresorbable barrier membranes are widely used in dentistry and maxillofacial
surgery. When the membranes are placed over bony defects and closely adapted to the
surrounding bone face, an environment that prevents ...
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 ...
