Thanks for inviting me to the party

I am new to nano and signed up for my first class in Nanotech as part of my metallurgy studies.
I have been surching the net for information on Nano as it relates to metallurgy.
What sort of research has been going on? where has it lead?
I would be interested in your comments or if you could point me to web sites where I could get more
information, I would be greatfull
