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 ...
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 ...
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 ...
Determination of some trace elements in echinacea purpurea by energy dispersive x-ray fluorescence spectrometry
(Proceedings / 3rd International Conference, Instrumental Methods of Analysis - Modern Trends and Applications, IMA '03, Thessaloniki, Greece, Septembar 23-27, 2003, 2003)
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 ...
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 ...
PZT ceramics obtained from mechanochemically synthesized powders
(Kluwer Academic Publ, Dordrecht, 2003)
PZT ceramics were obtained from the mechanochemically synthesized powders. Milling and sintering conditions were optimized based on results of density measurements, as well as on microstructural and electrical characterization. ...
Primena plazme u oplemenjivanju vune
(Srpska akademija nauke i umetnosti, 2003)
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 ...
Digitally graded GaAs/Al0.44Ga0.56As quantum-cascade laser
(Elsevier, Amsterdam, 2003)
A method for the optimal design and realization of a GaAs/Al0.44Ga0.56As quantum-cascade laser (QCL) is presented. Firstly, an optimal, smooth active region profile is derived, using inverse spectral theory. A digitally ...
