New Engineering Materials/New Applications for Materials That Have Been Around?

I’m in an introductory course to building construction materials and one of the goals of the course is to write a technical paper on any new engineering materials (5 years old is still considered new according to my professor) or any new applications for materials that have been around. Does anyone have any information/knowledge on where I can get started? Links,books, scholarly journals would be appreciated. Thanks
What can I do for u?
See wikepedia.org, u will find it in engg materials.
Thanx,
Bye
