Nanotechnology-this Is Our Future !!!

nanotechnology is reachin INDIA....(although quite late!!!!)
nanotechnology can make steel 100 times stronger with same size.....
machining can b xtremely accurate upto atomic level....
computers can consume billion times less power....
and the projections are endles.....
so wat do CRAZY ENGINEERS have to say bout this...
lets interact and share our knowledge !!!

This is no doubt inspiring. Swapnil, not many of us know about Nanotechnology. How about writing a short article on Nanotechnology and how is it going to affect us?

Of course, once we have a base, discussions can kick off in no time 😀 Anyone willing to take this up?

Hello rosh
Please write in layman's language. It will be helpful to all of us. 😀

Article:nanotechnology

In 1959,richard.p.feynman declared-"there is plenty of room at the bottom!"
then he went onto quote that "i am not afraid to consider the final question as to whether,ultimately,in the great future -we can arrange the atoms the way we want,the very atoms,all the way down!"
it was only in 1974,that this study of manipulation of units of matter was dubbed as nanotechnology norio taniguchi.it is derived from greek word for dwarf.nano is one-billionth part of a metre and roughly it is about length of 10 hydrogen atoms.
the point about nanotech is that it sets out to exploit the strange properties found in those very small worlds!
indeed small,no wonder this made scientists to comment like "the next big thing is really smalll!" and "any intelligent fool can make things bigger,more complex and more violent.but it takes a touch of genius and a lot of courage to make in the opposite direction!"
the beauty of this technology is that it allows to manufacture stuff with atomic precision.this will not only help scientist to come out with materials with improved properties but also helps in better understanding of its defects at atomic level.
finding the novel properties at nanoscale is one part but the most important part is to make use of those properties.and manipulation of these properties
will lead to stuffs which may seem not less than a magic!
some of the examples are as follows:
1.many companies over the world are working on materials that one day be made into solar cells in the form of paint!!![CHEMICAL ENGG.]
2.a comp. called nanosonic in virginia has created metallic rubber,which stretches like rubber but conducts electricity![MATERIAL SCIENCES]
3.GE's research centre in NY is trying to manufacture flexible ceramics
ie.a material that can be used in jet engine parts to help them run more effficiently at higher temperatures.[aerospace engg.]
4.then there is TiO2[titanium dioxide] chemical:this has very wide apllications.*a coating of this on window panes would make them self cleaning windows!**a coating of this on the outside face of the house,would help in absorption of atmospheric pollutants.*this injected into body can act as drug molecules to conteract tumours!...the list goes on and on and on!!!
still there are many more [so-called] magics of this technology that are already invented and still to be invented.but the latter part depends on how U can wave ur IMAGINATION and come out with some more STUNNING MAGICS!!!
the reason why i referred to imagination is because all these years[atleast for two years] you have written benzene structure.NOW DID U EVER THINK THAT THIS BENZENE has a gear like structure and can be used as a molecular gear[ie.indeed used as a nanogear]!!!
NOW THATZ NANOTECHNOLOGY FOR U!!!😁
😁 Had read about nanotechnology, but, i was really impressed by its ability to be used as concentrate contrast agent and anti-cancer drugs to improve imaging and treatment of cancer.

Fantastic job, rosh! 😁 . There's more to be discussed about this. Get in touch with me through email.

Nanotechonology hope so there wont be much space to talk about this future techonology.

But Notes mentioned about were so clear .

Cont with latest updates. Eagerly Waiting for it...

Anyone else studying "nano''? 😁

Good to hear that, Enmity 😀 . I'm sure our CEan tribe has many Chemical Engineers who are interested in Nanotechnology. I believe we all can make a difference by popularizing the subject through articles & discussions. What do you say?

In due course of time, as we gather more engineers, we can do something innovative in the field of Nanotechnology. That's actually a 'big thing' to talk about at this point of time 😁

Enmity, I guess, you know the subject better than others on CE. How about coming up with an article about the same?

hello friends........
Hey vijay! why don't you intro yourself at the Introduction threads here: https://www.crazyengineers.com/forum/forumdisplay.php?f=35

Oh, thanks for bumping up this thread, haha. This nanotech thing has great potential in the field of electronics too! 😁

- Some PDF links:
Nanotechnology for Communications (a short Motorola article)
Nanotechnology in Electronics: Present and Future (Interesting HP presentation)

- A 2005 article from eweek:
Nanotech Will Bring the World to Its Ears

Nanotechnology is a promising field, but also riddled with a lot of hype. Because the behaviour of materials at the nano-scale is quite different from bulk behavior, the properties of nanomaterials (particularly nanoparticles) are not always well understood and whats worse, do not always fit in with known theory so well.

So, extoll the virtues of nanomaterials by all means, but temper it with realism.;-)

Nanotechnology has the potential to impact the electronics/data storage industry the most in the short-medium term, for the medical side of things, we will have to wait a bit longer.

Had read about nanotechnology, but, i was really impressed by its ability to be used as concentrate contrast agent and anti-cancer drugs to improve imaging and treatment of cancer.
I work in a related field, and it is indeed promising, but see my statements above. Much of the behavior of these nanoparticles in-vivo is not well understood, and of the literature in the field, about 80-90% is junk, based on unreproducable empirical results.

We are atleast 5-10 years away from seeing nanoparticle based therapy systems result in a drastic leap over exisiting methods. Sure, small, incremental improvements are always going to be there, but for a big breakthrough, we need to wait a bit longer.
I want more to read about nanotechnology.

hey i missed this thread 😀
i had done a presentation on "nanotechnology in civil engineering" for CE-colloquim😁
check the civil engineering applications in here: Colloquium: Nanotechnology in Civil Engineering - CrazyEngineers
