In this study fabrication of three - and five - layer Al-Al2O3 graded composite (FGCs) including 5.7-18.7 vol% and 5.7-15.4 vol% of Al2O3 phase, respectively via ball milling of Al and ZnO powder and thereafter hot pressing at 5800C was investigated...

We considered polar optical phonon scattering,

deformation potential acoustic, piezoelectric and ionized

impurity scattering mechanisms, AlN is stable at high

temperature atmospheres and melts at 28800c. We...

In this study we examined how a popular social networking tool, Telegram, and an Islamic economic
