Synthesis of novel cyano quinoline derivatives
(Pergamon-Elsevier Science Ltd, 2015)
6,8-Dibromo-1,2,3,4-tetrahydroquinoline (2) and 3,6,8-tribromoquinoline (3) were converted into the corresponding cyano derivatives via copper assisted nucleophilic substitution reactions. While bromination of 6-bromo-8- ...
Effect of heat treatments on the microhardness and tensile strength of Al-0.25 wt.% Zr alloy
(Elsevier Science Sa, 2015)
In the present work, the effect of heat treatments on the microhardness and tensile properties of the Al-0.25 Zr (wt.%) alloy have been investigated. The Al-0.25 Zr (wt.%) alloy was melted in a vacuum furnace, and the ...
