“…In the year 1998 the process of tribomechanical micronisation and activation (TMA), as well as the appropriate equipment, was patented under number PCTP/1PB 99P/00757 in the International Bureau of the WPO PCT Receiving Office in Geneva (Lelas, 1998). Many studies have shown that tribomechanical micronisation can modify the physical, structural and functional properties of materials (Bhushan, 2000;Cefali, Nolan, McConnell, & Walters, 1995;Herceg, 2000;Herceg, Lelas, Brn ci c, Tripalo, & Je zek, 2004a;Lelas, Herceg, & Rimac-Brn ci c, 2003;Paveli c et al, 2000).…”
