the formation of these crystalline ZnO nanoparticles. Therefore, the understanding of the role of ball milling is necessary for the formation mechanisms and controlled production of ZnO nanoparticles. In the process, material particles are repeatedly flattened, fractured and welded during the high energy ball milling. Every time two steel balls ...

Mechanothermal (MT) method is one of the methods used for largescale production of carbon nanotubes/nanofibers. The different peculiar morphologies of carbon allotropes are introduced with an extraordinary structure for the first time by MT method. In this paper, the influence of milling time and annealing temperature on the crystallinity and morphology of the synthesized nanopowders was ...

Ester Vázquez and colleagues, Universidad de CastillaLa Mancha, Spain, report the use of a planetary retsch ball mill, which consisted of stainless steel balls within a grinding bowl, to cut and disperse singlewalled nanotubes (SWNTs). Air, high rotational speeds, and long milling times led to partial or almost total destruction of SWNTs.

The aim of the paper is to investigate the effect of size of multiwalled carbon nanotubes (MWCNTs) as additives for dispersion in gear oil to improve the tribological properties. Since long pristine MWCNTs tend to form clusters compromising dispersion stability, they are mildly processed in a ball mill to shorten the length and stabilized with a surfactant before dispersing in lubricant.
