Applications
Specific synthesis processes are used to
Various nanoparticles
The defined production and reaction conditions are crucial
Obtaining such paricle dependent size.
Particle size, chemical composition, crystallinity and shape
It can be controlled by temperature, ph-value, concentration,
Chemical composition, surface modification and
process control.
Nano material or nano particles are used in a broad spectrum
Two basic strategies are used to produce nanoparticles ...
From top to bottom and
From bottom to top.
From top to bottom:
The production of very small structures of larger pieces of material.
One way of achieving this is the mechanical grinding of the solid in
Fine nano powder (ball milling)
From bottom to top:
The atoms or molecules are organized in a structure
To its natural properties
For example: grown crystals
(or)
In the bottom-up stratosphere, structures are constructed by chemical processes.
