Among the topics are synthesizing zinc oxide nanoparticles by solid state reactions and its influence on a zinc electrode, the effect of isothermal treatment
on the microstructure and properties of high performance steel, simulation and casting processes for ductile iron wind generator rotor shaft, effects of additives on semiconduction transformation in lead zirconate titanate ceramic induced by atomic hydrogen, tungsten cathodes doped with rare earth for pulsed xenon lamps, and the shielding effect in the sacrificial anode cathodic protection system.
Nahouji is a researcher who evaluated the effect of nanostructuring on the formation of age hardening precipitate as well as examining the thermal stability of nanostructured Al6061 alloy (produced by mechanical milling) during isothermal treatment
and identifying the mechanism governing grains growth."Commercial Al6061 alloy chips together with stearic acid (as process controller) were milled in a planetary ball mill.
