New process of developing nanocrystalline FeCr for fuel cell application

The objectives of this study are to explore the high energy ball milling combined with ultrasonic treatment to develop smaller crystallite size, finer surface morphology, higher thermal stability and more homogenous nanocrystalline FesoCr20 alloys. The process that combined both is not hlly investigated. They are carried out by high energy ball milling with milling time of 60 h and ultrasonic t…

Preparation of nanocrystalline y-Alumina using ultrasonic technique

The γ-alumina powder is a potential material for washcoat application. This paper shows the preparation of γ-alumina using ultrasonic technique in order to obtain nanocrystalline of γ-alumina powder. The 50 gr of the γ-alumina powders was treated in the 250 gr ethanol solution using ultrasonic technique within 10, 20, 30, and 60 minutes, respectively. The process of sonication was set at th…
