Hi......!
Is there any body who can guide from where I can get details of
different methods for nanoparticles synthesis. Is there any website
containing tutorials about that. please guide im biginner in this
feild. Thanks

Nanoparticles occur in the environment usually without deliberate
synthesis. If you can tell us more about your application in mind, that
might help narrow down things a little.

Dear Zia Naqvi,
There are a lot of different synthesis approaches applicable to inorganic
nanoparticles.
In our research group, recently, we introduced a general nonaqueous method
for the synthesis of many oxidic nanoparticles. It is what we call the
benzyl alcohol route. Under the same conditions it is possible to
synthesize perovskites (BaTiO3, SrTiO3, BaZrO3,...), conducting oxides
(SnO2, In2O3,...) and many other like: TiO2, V2O3, ZrO2, Nb2O5, Ta2O5, HfO2...

Futhermore the yeld is nearly 100% and large quantities are easily
obtainable.

If you are interested in this approach you can visit our website

or reading the following articles:

I hope I could answer at least partly to your question! If you have some
question do not hesitate to contact us!

The answer to your question would fill textbooks. Dozens of
them. Actually I have come across some which are dealing with
this issue, perhaps you should take a look on Amazon.

It would help, if you could be a bit more specific in what
type of material are you interested in: metals, oxides,
semiconductor, magnetic, organic, catalytic?

Methods for producing nanoparticles include:
* gas-phase (plasma, pyrolysis), e.g. SiO2, TiO2
* precipitation, also in compartementalized systems,
i.e. microemulsions, micelles, e.g. SiO2, Ferrites, ZnO
* electrochemical, e.g. ZnO
* mechanical attrition
* hydro-thermal, e.g. TiO2
* sol-gel, organically modified SiO2, ZrO2
* polymer synthesis, all kinds of organic material
* special ones, e.g. carbon nanotubes, buckyballs

All of these can be found in current literature (scientific
and patents)
