[quote]Nanomaterials is a branch of the field of materials science which deals with materials having morphological features smaller than 100 nm in at least one dimension. This classification includes thin films, quantum dots, etc. When matter is reduced to the nanoscale (1 - 100 nm,) the effects of increased surface-area, in tandem with quantum effects, begin to dominate material properties. As a particle's size decreases, a greater proportion of its atoms are found at the surface compared with those inside. Larger surface area equals greater reactivity. Quantum confinement results in size-dependent property changes, meaning materials with nanoscale dimensions (nanomaterials) can start to exhibit very different optical, electrical and magnetic properties, (especially as the structure or particle size approaches the smaller end of the nanoscale) compared to what they would on a macroscale. This effect has been likened to an expansion of the entire periodic table of the elements out into another dimension; as though we now have access to many new primary elements which did not exist before, enabling unique/novel applications. For instance, when made into nanoparticles, opaque substances may become transparent (copper); inert materials attain catalytic properties (platinum); stable materials turn combustible (aluminum); solids become liquids at room temperature (gold); insulators turn into conductors (silicon). Materials such as gold, which are chemically inert at normal scales, can serve as a potent chemical catalysts at the nanoscale. Much of the fascination and potential of nanotechnology stems from these unique surface area and quantum phenomena exhibited by matter at the nanoscale.
Nanomaterials are not simply another step in the miniaturization of materials. They often require very different production approaches. There are several processes to create nanomaterials, classified as "top-down" or "bottom-up." Although many nanomaterials are currently at the laboratory stage of manufacture, a few of them are being commercialised.[/quote]

And then a rebellion uprising occurs.
I just remembered, I have a friend who wants to be a nanotech engineer.
Oh that's a pretty tall mountain, we should get in touch again someday, stupid facebook requiring me to give away my phone number for their conspiracy :unsmith:
I hope I'll live to the time where Nano-Technology is used in a daily basis.
I am looking forward to more powerful computers, computers that can solve our problems for us simply by thinking about them. Eventually even AI.
Its sad that in our lifetime that all the things we dream about, we'll probably just barely see it if at all
I'd love to have those blood cells!

Death stars in our blood vessel? I rather not.
I'm gonna miss the primitive times (present day)
fuck I'll just use nanotech to make my own race of people and my own planet.god wouldn't that be fun?
or my own island/continent(like australia) on earth as my own country.
boy can one man dream......
This thread gives me more hope for the future than anything I've ever seen.
Thank you, Eudoxia.
Also, I'm mentally doubling all of the projected times of release. 10 years from now? See it in 20 years... Still, this opens up thousands of doors, and in the end, 5 years won't be that big of a deal.
Edit: Where did I pull 5 years from...

Considering Hofstadter's Law and the fact that all fields of research are filled with over-confidence (Look at AI and how they said "We'll have HAL 9000 in ten years no biggie" 60 years ago), I'd say molecular assemblers will be available by 2040. 2060 is the most pessimistic date.
Recoding the genome with nanobots is a must if humans want to evolve properly. If we do not modify our own genes, we are pretty shit fucked.

ah yes, the infinite power of nano-augmentation!

Looks like a dong.
I welcome our new nano overlords.

Co-discoverer of buckminsterfullerene (which gave rise to the infamous Buckyball) which created a foundation for nanotechnology, and overall awesome dude. I've actually been to one of his lectures and I have his signature. Believe me, he's a fucking awesome dude.
If this stuff can enhance muscles, cognitive capabilities, bodily integrity, immune system, etc, then it could theoretically turn someone into some kinda superhero. Y'know, that'd be strange, everyone being super. Everyone would have extreme superhuman capabilities, but it wouldn't be special compared to everyone else.
Its all about the Piezoelectric shirts man.
That sounds a bit too good to be true
Those claims of practical use of nano-manufacturing in ~10 years are very optimistic, in my opinion, but one can hope.
If the whole grey goo scenario happened, couldn't we just stop with an emp?
[QUOTE=Firefox42;25462179]If the whole grey goo scenario happened, couldn't we just stop with an emp?[/QUOTE]
Grey goo probably won't happen at all, how will you supply power to billions of little -- Well, nevermind. If it did, it's just a matter of an EMP (I think) or just having a radiation source.
The nanorobots may be cool but they can't fight back if radiation begins ionizing their compounding atoms. It would literally be grey goo, a grey goo-ish ooze thingee on the ground that doesn't spread.
Well actually it would be more like black probably but whatever.
Where do i sign up to live forever?
No mentioning of macroscopic applications for nanotechnology? Like, that you can make carbon nano tubes, weave them together and its like 1000 times stronger than steel? Nanotechnology doesnt solely open up a world of miniaturisation, theres also huge potential for bigger stuff.
These science threads are awesome. :3:
mutter mutter mutter something about mankind's hubris being its downfall

I always make the stargate reference. always.
What nano tech will do for medical technology will be amazing. I plan to live to at least 100. But... What if in 100 years, they'll have the technology to make me live even longer, what about then, is there a critical age were you will just live forever?

God, cells are complicated. Intelligent design's got nothing on evolution... for now.

The explanation if you wanted it.
I remember that video, I had to watch it like 10 times to figure out what they were talking about.
