Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.it refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products.

You will be driving an electric car in the near future.
Current (pardon the pun) battery technology is just not good enough. Anybody doing university entrance chemistry should pay extra attention to electrochem.
Especially fascinating are ultracapacitors and the latest research seems to be centered on graphene.
The science site that I look every day is http://www.physorg.com/. The best general science news you can get.
Recently on that site ( 2011) I read about Chemically Modified Graphenes- a monolayer of conducting material which at the moment represents the highest theoretical surface area per mass of anything known. For energy storage in battery powered passenger aircraft a more novel material is required. Get going.
As with any crossing of a technological frontier, the possibilities and dangers are numerous. The medical advances that would be possible are intriguing and staggering. Think of heart surgery from within the heart, without breaking the skin to get there. Think of attacking cancerous tumors or growths at the cellular level, without the horrible side effects of chemo or radiation. But the unknown, unplanned, possibly disastrous uses of such technology would also most certainly come to pass.
thank you sir............the site z actually very good
hmmmm thats a very interesting area
