cell disruption. bead/ball mill – these mills use small grinding media to act against cells by one of two methods. the dyno®-mill and beadbeater series use agitator discs inside an enclosed chamber to whip the beads into a high-shear frenzy which then collide with the cells and produce breakage.
a modified ball milling device having assistance of ultrasonication was employed in the synthesis of zinc oxide nanoparticles. the synthesis of nanoparticles involved analytical grade zinc acetate dihydrated salt as the zinc precursor material. ball milling medium of stainless steel with diameter of balls of 2 mm was employed. the ratio of
ultrasonic wet-milling and micro-grinding. ultrasonication is an efficient means for the wet-milling and micro-grinding of particles. besides dispersing and deagglomerating, the wet milling is an important application of hielscher ultrasonic devices.. in particular for the manufacturing of superfine-size slurries, ultrasound has many advantages, when compared with common size reduction
meanwhile, particle sizes of cnp underwent ultrasonication without ball milling decreased with the increase in ultrasonication time due to the longer exposure time to cavitation effect produced by ultrasonic probe. the optimum ball milling and ultrasonication time were found to be 18 h and 15 min, respectively.
