Change the name and enjoy the File on Synthesis of nano materials. It is a really brief file can be used in small level presentation eg for the university students amd etc in educational field

1. Synthesis of Nano Materials

2. Introduction to Nano materials:
 The materials having particles or constituents of nanoscale dimensions, or one that is
produced by Nano technology.
 A nano-scale is measured in between 1- 100nm.
 For example: carbon nano-tubes are used in water & environmental remediation and
in manufacture of composite materials.

3. Synthesis of nano materials:
 Synthesis of nano materials include 2 approaches or ways that can be used
in different methods to synthesize nano- materials.
 Nano materials exist in between the scale of macro and quantum scale.
 Macro = >100nm & quantum = <1nm and nano scale is from 1-100nm
1) Top down approach
In this approach the nano
material is made from a
macro (Bulk) material.
2) Bottom up approach
In this approach the nano
material is made from a tiny
quantum material.

4. Top down approach:

5. Bottom up approach:

6.  There are major 3 three methods for the synthesis of nano - particles.
Methods For The Synthesis Of Nano Particles:
Physical methods
Chemical methods
Mechanical methods

7. Physical methods
These methods of
synthesis of nano-
materials are of really
high cost.
These include vapor
condensation, laser
ablation, chemical vapor
deposition etc.
Chemical methods
These methods are
also expensive.
These methods
include chemical micro
emulsions, epitaxial
growth, colloidal
deposition, sol-gel,
hydrothermal route etc
Mechanical methods
These methods
include mechanical
grinding, high-energy
ball milling, mechanical
alloying, reactive milling.
The advantage of
these techniques is that
they are simple &
require low cost
equipment and provided
that a coarse feedstock
powder can be made
the powder can be
processed
