Japanese scientists create new anti-shock material from carbon nanotubes - Polidicks

[url=http://www.reuters.com/article/idUSTRE6B151E20101202]source = reuters[/url] [quote=Reuters](Reuters) - Researchers in Japan have invented a new shock-resistant material [B]that can withstand extreme temperatures,[/B] which they hope can be used in the engines of spacecraft and cars. [B]Made entirely of carbon, it can flow and stretch slowly like thick honey and spring back to its original form,[/B] said materials scientist Xu Ming at the National Institute of Advanced Industrial Science and Technology in Japan. [B]"It looks like a metal sponge that is porous, it is made from trillions of entangled carbon nanotubes,"[/B] she said in a telephone interview. [B]"When you stretch and release it, it can come back slowly (to its original shape)."[/B] A report on their invention was published on Friday in Science magazine. [B]Grown in a mixture of silicon, iron and water, the carbon nanotubes are 5 nanometers in diameter, and can retain their form and function within a huge temperature range of between -196 and 1,000 degrees Celsius in an oxygen-free environment.[/B] A nanometer is a billionth of a meter. "This material is totally new and unique. [B]It can potentially be used in space, in fuel tanks of spacecraft and rockets, in car engines to isolate vibration,"[/B] Xu said. "There is no other material showing such stable properties ... [B]unlike rubber which cannot conduct electricity, our material has electronic connectivity, so it can be used in more applications,"[/B] Xu said.[/quote] Yeah the article's short but interesting nonetheless. As always, I've bolded the parts I find most interesting or relevant if you can't be fucked to read the entire thing. I love carbon nanotubes :dance:

somehow this will be used in porn

Carbon nanotubes. What[B] cant [/B]they do?

Damn gooks need too get off my technology!!!! [highlight](User was banned for this post ("Why reply/racism" - Jaanus))[/highlight]

Reading the bold text, this sounds like the perfect condom.

except carbon nanotubes are so small that they can pass through almost any filter; causing asbestos-like lung problems when inhaled.

[QUOTE=johan_sm;26460039]You're not supposed to use individual tubes[/QUOTE] It's inevitable that some of these tubes will break-off and get into your lungs. Carbon nanotubes have better conductivity than copper, but the fact that they cause health problems has nearly stopped research and development with them.

[QUOTE=M4 Sherman;26460515]Carbon nanotubes have better conductivity than copper, but the fact that they cause health problems has nearly stopped research and development with them.[/QUOTE] I wouldn't say that, but the issue has certainly made scientists step back and say "oh shit, we need to slow down and put more effort into studying the long term health risks of these things before we start making everything out of them and releasing them to the public."

Meh Id rather have some batteries than last days longer with a risk of cancer than constantly having dead batteries. Everything causes cancer nowadays anyways so I cant say Id care much.

if anything, it's reason to increase it so these problems can be overcome and the enormous advantages of CNTs in many fields can start being utilized

Up, up and away! [img_thumb]http://www.acceleratingfuture.com/michael/blog/images/SpaceElevator.JPG[/img_thumb] Now, I want to see what applications this will have for robotics. Sounds like the perfect skin for a snake.

so you guys want an electrically conductive metal condom with holes in it specially designed for her pleasure

An interesting new material, so many applications. [QUOTE=CabooseRvB;26459897]Reading the bold text, this sounds like the perfect condom.[/QUOTE] But is it smooth to the touch? That's the real question, 'cause you don't want to get it grated.

[quote]Carbon nanotube-enhanced thermal destruction of cancer cells in a noninvasive radiofrequency field. Gannon CJ, Cherukuri P, Yakobson BI, Cognet L, Kanzius JS, Kittrell C, Weisman RB, Pasquali M, Schmidt HK, Smalley RE, Curley SA. Department of Surgical Oncology, The University of Texas M. D. Anderson Cancer Center, Houston, Texas 77030, USA. Abstract BACKGROUND: Single-walled carbon nanotubes (SWNTs) have remarkable physicochemical properties that may have several medical applications. The authors have discovered a novel property of SWNTs-heat release in a radiofrequency (RF) field-that they hypothesized may be used to produce thermal cytotoxicity in malignant cells. METHODS: Functionalized, water-soluble SWNTs were exposed to a noninvasive, 13.56-megahertz RF field, and heating characteristics were measured with infrared thermography. Three human cancer cell lines were incubated with various concentrations of SWNTs and then treated in the RF field. Cytotoxicity was measured by fluorescence-activated cell sorting. Hepatic VX2 tumors in rabbits were injected with SWNTs or with control solutions and were treated in the RF field. Tumors were harvested 48 hours later to assess viability. RESULTS: The RF field induced efficient heating of aqueous suspensions of SWNTs. This phenomenon was used to produce a noninvasive, selective, and SWNT concentration-dependent thermal destruction in vitro of human cancer cells that contained internalized SWNTs. Direct intratumoral injection of SWNTs in vivo followed by immediate RF field treatment was tolerated well by rabbits bearing hepatic VX2 tumors. At 48 hours, all SWNT-treated tumors demonstrated complete necrosis, whereas control tumors that were treated with RF without SWNTs remained completely viable. Tumors that were injected with SWNTs but were not treated with RF also were viable. CONCLUSIONS: The current results suggested that SWNTs targeted to cancer cells may allow noninvasive RF field treatments to produce lethal thermal injury to the malignant cells. Now, the authors are developing SWNTs coupled with cancer cell-targeting agents to enhance SWNT uptake by cancer cells while limiting uptake by normal cells.[/quote] [url]http://www.ncbi.nlm.nih.gov/pubmed/17960610[/url] [url=http://www.nanowerk.com/spotlight/spotid=2035.php ]Nanotube Cancer Treatment Shows Promise[/url]

To all the HURR CANCER people: Coat the nanotube sheet in mylar. No, seriously. That's it.

There is massive research going into carbon nanotubes and as soon as there is a cheap way to mass produce them they will be used in just about everything.

Why don't the news add pictures about this? They never provide pictures of these kind of stuff.

Great
