To evaluate the mixing effectiveness of dry ball-milling, multi-walled carbon nanotubes were ball-milled with boron carbide powder, and the resulting mixtures were hot pressed to consolidated tiles. Density, hardness, Young's modulus, and fracture strength of the tiles were measured; all decreased with increasing nanotube content.

The ball milling technique has also been applied to the synthesis of calixarenes, rotaxanes and cage compounds, asymmetric synthesis as well as the transformation of biologically active compounds. This article is part of the themed collection: …
