Introduction

Bottom-up refers to methods where devices 'create themselves' by selfassembly. Chemical synthesis is a good example. Bottom-up should broadly speaking be able to produce devices much cheaper than top-down methods, but getting control over the methods is difficult when things become larger and more bulky than what is normally made by...Synthesis of nanomaterials by a simple, low cost and in high yield has been a great challenge since the very early development of nanoscience.

The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling ...For instance, high energy ball milling is a top-down method using planetary ball mills. To obtain optimized milling parameters in a planetary ball mill, many trials are needed. Hence optimization of the milling parameters through modeling tools is necessary to reach economically efficient and time-saving synthesis of nano-fertilizers.
