Chapter Bottom-Up and Top-Down Approaches for MgO

The top-down approaches are preferred for growing thin films where bulk material is used for depositions. The methods, which are frequently used, are radio frequency sputtering, pulsed lased deposition, and molecular beam epitaxy and e-beam evaporation. Sometimes, methods like mechanical milling and high energy ball milling are used to grow

Synthesis of Nanofertilizers by Planetary Ball Milling

Feb 12, 2020 Most nanofertilizers are synthesized by a bottom-up approach, which is a complex and requires sophisticated instruments. The top-down approach is an alternative method for large scale and low cost of production. For instance, high energy ball milling is a top-down method using planetary ball

Jul 11, 2017 There are two approaches for size reduction, namely, bottom-up and top-down approach. In the former approach, controlled precipitation of the drugs is achieved using a suitable non-solvent. Addition of non-solvent results in super-saturation and nucleation, leading to smaller particles. 14 The major disadvantage of this method is the presence
