such as atoms or molecules is called bottom-up approach. Ex Chemical vapour deposition Sol-Gel Process Chemical Reduction methods etc. ii Top-down approach The process of making nanostructures starting with larger structures and breaking away to nano size is called top-down approach. Ex Lithography Ball milling Epitaxy etc.
Jun 15 2012 Steps in ball milling method; 1. As the name suggests the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron hardened steel silicon carbide or tungsten carbide balls are made to rotate inside a mill
to nanoscale top-down approach or building up nanoiron from atoms generated from ions or molecules bottom-up approach 811. 2.1. Top-Down Synthesis Top-down methods for nZVI production are the milling processes pulsed laser ablation and noble gas sputtering Figure 2. The most frequently used top-down method is the milling process.
Ball milling technique using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore mineral dressing preparing talc powders and many .
Ball MillBottom Up Approach Ball Milling Method. Bottom up approach ball milling and lowenergy ball milling and sonication 14 are some of examples of topdown the other hand methods such as chemical vapour deposition 15 van der waal epitaxial growth on substrate 16 and hydrothermal approach 17 are some of common bottomup low yield methods are timeconsuming and costly.
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
approach and 2 the bottom-up approach. Both approaches have advantages and disadvantages. Attrition or milling is a typical top-down method in preparing nanoparticles whereas chemical precipitation involving the building up of the atom or molecular constituents is a typical bottom-up

FeCo MNPs are also reported by using a wet chemistry method23 which also belongs to the bottom-up approach. In contrast for the top-down approach MNPs are made from raw bulk materials that are broken down to small nanoparticles such as the ball milling
Apr 23 2021 Bottom up approach is binding of small size individual molecules into bigger and complex structure in order to form nano-sized material . The present study is an effort to synthesis nano-sized silicon carbide using planetary ball milling technique of top down approach and development of nano composites using synthesized nano-SiC particles .

The bottom up approach involves precipitation or chemical synthesis; the top down approach uses jet milling wet ball milling and HPH. These methods may be combined; for example bottom-up plus top-down precipitation to supra-micron particles followed by milling or top-down plus top-down micronization followed by nanonization.
