[ 1 ] - بررسی خواص حسگری لایههای اکسید قلع نانوساختار لایهنشانی شده به روشهای تبخیر گرمایی و کَند و پاش نسبت به اتانول
In this paper, manufacturing and evaluation of ethanol gas sensors based on thin films of nanostructure tin oxide have been investigated. SnO2 thin films were prepared by both thermal evaporation (type I) and sputtering (type II) methods and heat treated on silicon wafer substrates. Scanning electron microscope (SEM), atomic force microscope (AFM), X-ray diffraction (XRD) and energy dispersive ...

In this article, sintering activation methods of Mo powder (chemical, mechanical and surface activation) were studied. For this purpose, the milled/reduced Mo nanopowder was sintered at 900, 1100 and 1400 ºC for 1 hr. For comparison of sintering activation methods (mechanical and chemical activation) and their effects on microstructural characteristics, commercial micropowder Mo as well as Ni ...
