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 ...

In the current study, 247 articles dealing with the use of SNSs (social network sites) in education and published in Social Sciences Citation Index (SSCI) journals up to 2015 were analysed. The articles' demographic (year, ...
Convenient synthesis of disubstituted tacrine derivatives via electrophilic and copper induced reactions
(Pergamon-Elsevier Science Ltd, 2016)
The bromination of 2-aminobenzonitrile (2) with molecular bromine (2 equiv) furnished 2-amino-3,5-dibromobenzonitrile (7) in 98% yield. One-pot syntheses are described for dibromotacrine derivatives (6,14-18) utilizing ...
Effect of heat treatment on the microstructures and mechanical properties of Al-5.5Zn-2.5Mg alloy
(Elsevier Science Sa, 2016)
The Al-5.5 Zn-2.5 Mg (wt%) ternary alloy was prepared using a vacuum melting furnace and a casting furnace. Microstructural and mechanical properties of the alloy were investigated as-cast and under heat-treated conditions. ...
