Synthesis of Nanomaterials

1. Below the 100-nm mark is not enough, and the synthesis parameters must be controlled so that the following
conditions are met:
(1)Identical NPs are made every time (i.e., same diameter and shape);
(2)They have the same morphology;
(3)The same crystal and chemical bonding occurs whether on the surface or inside the NPs; and
(4) The synthesis process must be stable.
If these four conditions are met, then the synthetic process can be considered as reproducible and is a reliable
technique.
SYNTHESIS OF NANOMETER-SCALE MATERIALS
In nanotechnology, there are two main
methodologies used to design and
manufacture NPs and nanometer-scale
structures; the first is the top-down
method, and the second is the bottom-up
method.

2. Top down Bottom Up

4. Ball Milling Process

7. Evaporation Techniques
