Magnetization and Specific Absorption Rate Studies of Ball ...

One aim of the study was to assess the effect of milling time and surfactant concentration on the derived nanoparticle size distributions. Previous studies on ball-milled iron oxide nanoparticles have addressed the question of mean particle size as a function of milling time . To our knowledge, the dependence of mean particle size on surfactant ...

Investigation of the interfaces of silicon-silicon dioxide ...

This work studies the properties of CuInSe{sub 2} (CIS) thin films obtained from nanoparticle powder. The samples were prepared by direct thermal evaporation of ball milled powder from a tungsten crucible onto precleaned glass substrates, using a BALZERS coating unit. The as deposited films were annealed in a vacuum at different temperatures.

A mixed powder of Mg and amorphous B was ball milled for 4 h. The milled powder was packed in a pure Fe tube and then cold rolled into a tape specimen. A heat treatment was performed at 600 C for 1 h under an Ar atmosphere and subsequently furnace cooled. MgB2 tape specimens without the ball-milling treatment were also prepared for comparison.
