HAI ROOM, ANY ONE HAVING BASIC IDEA ON WHAT IS NANOTECHNOLOGY, COULD U PLS EXPLAIN THE CONCEPT ABOUT NANOSCALE SCIENCE.

Well Reed, I cannot respond to your query, but while I'm here:

Welcome to the UT Forums!

Well, A basic rundown of nanotechnology?... It is basically what it says in its name "Nano" - Very small, usually this is associated with Nanobots which are microscopic machines, the most aticipated application for these tiny machines is in the field of medical science. They could potentially allow for the repair of indavidual cells or even killing off infectious viruses. Although they are not limited to just that... here are a few pictures of what nanobots may look like in the future:

Nano technology is also being used in the aerospace department for creating extremely strong fibers called carbon-nanotubes, they will use nanobots to weave these small fibers into something that can be used such as a space tether B)


Hope that helps, and welcome to the forum

Nanotechnology is used in tissue engineering and DNA processing.

Hi/welcome kapilsreedhar1984

You may want to make your text nano sized :D :lol: ;) LOL.
Using caps is considered shouting when posting in forums.

Just a little friendly advice ;)

Nanotechnology is working with materials small than 100 nanometers in size. As stated above, there are numerous applications being investigated. Hagar has used engineered nanotech fibers that repel liquids, so when you spill water on your pants it just runs right off without absorbing and staining. The newest computer chips individual transistors are now in the nanotech size range, and they're looking to go even smaller. Anyone working with bucky balls and carbon nanotubes are working in the nanotech range. As mentioned above, the long term goal are machines that can move through our bodies fighting disease and repair individual cells, or huge swarms of them that can be fed a pile of raw materials and a design and create a finished product by assembling it one molecule at a time.

The dark side is the grey goo scenario and nanotech weapons. The Grey Goo is the idea of creating nanotech machines that can use any raw material around them to manufacture new copies of themselves. The purpose of these would be replacing damaged medical nanomachines inside your body, or in a manufacturing plant, but the worry is that if one goes wrong and just continuously replicates itself, over a very short time these faulty nanomachines could consume all matter on the surface of the Earth to make more copies leaving nothing but a grey goo of tiny nanomachines covering the surface of the planet. The military side is that this could be launched intentionally against an enemy, or some other kind of nano attack that could disable systems in the enemy's military or country.

chrome star, thks for the caution with the caps! well i am new to blogs, so i dont know really how to behave in blogs, and i thank all of u ppl for giving useful info about nano science, especially all those websites! keep posting more!

Aerogels (http://en.wikipedia.org/wiki/Aerogel), very interesting stuff. I believe it is made with the use of nano-technology.

I wounder if it's possible to make a lighter then air aerogel. Sure it wil need o hold some other gas the common air but still.

I believe they made it already. Read this (http://www-cms.llnl.gov/s-t/aerogels_guinness.html).

I do not know how expensive such a material would be or if it can be cheaply massproduce but the implications are interesting. Iwounder how theae materials are made, like can they be poored out of some kind of cannister or sprayed and left to harden? Making a lifing body of this stuff may be interesting as well.

Maybe you'll find this (http://homepages.cae.wisc.edu/~aerogel/aboutaerogel.html)
interesting.

Another thing you need to do kapilsreedhar is check out the Forum rules, just fallow them and you will be all set to go, and you will never get into trouble.

Welcome to the BAUT Forum!:dance:

This really doesn't belong in ATM, so I've moved it to General Science.

...i thank all...for...those websites! keep posting more!Spray-on liquid glass, anyone?
...When asked about how the technology works, Neil, said “In essence, we extract molecules of SiO2 (the primary constituent of glass) from quartz sand, and then we add the molecules to water or ethanol...there are no added nano-particles, resins or additives---the coatings form and bond due to quantum forces. Our research informs us that in all probability, we offer the most versatile coating in the world...The concept of spray -on glass is just mind -boggling”...now available for domestic use in Germany...retail availability in the UK will commence in early 2010.

nanotechnology right now are those molecular machinery-components and smart materials that have being made throughout the last decade but never get kicked off the lab because we don't have any infrastructure to mass produce them.

i think that only once Moores law drives computer circuits into the nano-scale we will have the economical backbone to build such an infrastructure. until then its just a name we give to a bunch of cool microscopic things in labs.

I'll have to wait for home for the youtube video (blocked at work), but I'm not blown away. People have done spray-on amorphous silica coatings by a variety of technologies. "Water glass" (sodium meta-silicate) has been around for centuries. I'm sure there are incremental improvements here, but this isn't mind blowing (at least to me).

...I'm sure there are incremental improvements here...Breathable, flexible and 100 nm thin---can't wait to paint my car with a few cans of it, since today's automotive clear-coatings seem to fade and peel after just a few years...assuming it will be "affordable". Wrote to the manufacturer about obtaining some from Germany (where the article stated it is currently available), and their reply assured me:
...We will attend to your email during the next few days... http://www.bautforum.com/images/icons/icon10.gif

No, it's mostly films, particles, and lithography techniques, and metallurgy and polymer science. It's not just out of the lab, it's become pervasive. Computers are full of it...the magnetic film on the hard drive platters, the sensors that read the data from them, the integrated circuits, the liquid crystal display...

Little molecular robots are what sci-fi usually means by nanotechnology, but the field is not at all restricted to such things.

They've been at that scale for decades. 800 nm fabrication processes were introduced around 1990. Some parts are currently being made with 32 nm feature sizes.
