The effects of microalloying with silicon and germanium on microstructure and hardness of a commercial aluminum alloy
(Journal of the Serbian Chemical Society, 2003)
The effect of small additions of Si and Ge on the microstructure and hardness was investigated during aging of a commercial 2219 aluminum alloy It was found that for the same level of microalloying in alloy 2219SG (containing ...
Unidirectional stripping extraction from a cyclotron which accelerates light as well as heavy ions
(Physical Review Special Topics - Accelerators and Beams, 2003)
The VINCY Cyclotron (VINca CYclotron) is a multipurpose machine intended to accelerate light as well as heavy ions. To extract heavy ions with low energy and light ions an extraction system with stripping foil is used. ...
Morphology of RuO2-TiO2 coatings and TEM characterization of oxide sols used for their preparation
(Journal of Colloid and Interface Science, 2003)
Characterization of RuO2 and TiO2 sols of different aging times, obtained by forced hydrolysis of appropriate chloride salts, was performed by transmission electron microscopy (TEM). The aging time of TiO2 sols was observed ...
An experimental and modeling study of the contribution of coal ash to SO2 capture in fluidized bed combustion
(Chemical Engineering Journal, 2003)
The process of sulfur self-retention (SSR) occurs as a result of the reactions between the mineral matter in coal ash and the SO2 evolved during coal combustion. Consequently, the emission of SO2 may be significantly ...
Effect of curing time on the fraction of Cs-137 from cement matrix
(Annals of Nuclear Energy, 2003)
To assess the safety of disposal of radioactive waste material in concrete, curing conditions and time of leaching radionuclides Cs-137 have been studied. Leaching tests in concrete were carried out in accordance with a ...

Criticality safety of low-enriched uranium and high-enriched uranium fuel elements in heavy water lattices
(Nuclear Science and Engineering, 2003)
The RB reactor was designed as a natural-uranium, heavy water, nonreflected critical assembly in the Vinca Institute of Nuclear Sciences, Belgrade, Yugoslavia, in 1958. From 1962 until 2002, numerous critical experiments ...
Comparison of the radiotoxicity of two alpha-particle-emitting immunoconjugates, terbium-149 and bismuth-213, directed against a tumor-specific, exon 9 deleted (d9) E-cadherin adhesion protein
(Radiation Research, 2003)
We investigated the effects of the a-particle emitters Tb-149 and Bi-213 coupled to a tumor-specific antibody targeting the mutated delta 9 E-cadherin (d9 E-Cad) on single cells and cell pellets. The d9 mutation of the ...
Nonlinear drift waves in electron-positron-ion plasmas
(Physical Review E, 2003)
It is suggested that low-frequency drift waves can play an important role in the dynamics of electron-positron plasmas comprising some concentration of ions. In the electromagnetic case the drift wave couples with the shear ...
Ion-beam mixing in Fe/Si bilayers by singly and highly charged ions: evolution of phases, spike mechanism and possible effects of the ion-charge
(Applied Physics. A: Materials Science and Processing, 2003)
Silicide formation and ion beam mixing of Fe/Si bilayers due to Ar-, Xe- and Au-ion irradiations at room and liquid-nitrogen temperatures were investigated. For the study of silicide phase formation, the Fe/Si bilayers ...
