Properties of dispersion-hardened copper made by internal oxidation of prealloyed copper powder containing 2.5wt. % Al
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Prealloyed copper powder containing 2.5wt. %Al was processed in a planetary ball mill to evaluate matrix hardening due to formation of Al2O 3 particles in situ by internal oxidation. After milling, the powders were heat ...
Apparent enthalpies of activation for oxygen reduction at Pt3Co electrode in alkaline solution
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
Oxygen reduction (OR) at a Pt3Co alloy electrode has been examined in alkaline solutions of different pH's in the temperature range from 274 to 313 K. At all temperatures, two distinct E-log j rep-ions are observed. At low ...
Levels of PAHs in the soils of Belgrade and its environs
(Springer, Dordrecht, 2007)
Polycyclic aromatic hydrocarbons (PAHs) were analysed in 39 soil samples (0-10 cm upper layer) collected in Belgrade, the capital of Serbia. The sampling sites were randomly selected from urban, urban/recreational and rural ...
