Fun With Nanotechnology Advances
wieselwerkstatte sent us a link to a Nature article that talks about the possibilty for self-soldering molecular wires. In related news, demon-cw sent us a C't story about .2 buckyballs that they are using to create nanotubes. Use the fish for those who don't speak German.
Who modded this up?
Christ, people, this is totally off topic.
So he's in the nanotech industry (or so he says). What does he want, a cookie!?!
Nanotech isn't just science fiction anymore! People are just beginning to notice. First application -- probably synthesizing experimental pharmaceuticals in small lots for testing.
InstaPundit! Ahead of the Curve Since 30 Minutes Ago
So far nanotech is a fascinating batch of lab playthings; I'm holding my breath for the first really public use of a nanotechnology. Even if it's nothing terribly complex, like a new insulating material or a way to desalinate water. I'm not saying those are what should be done, just that it'll be interesting to see what the first buy-off-the-shelf application will be.

What is it with buckyballs ? why does everything come from buckyballs ? Why couldn't a beowulf cluster of dodecahedrons do the job ? I just can't imagine any media scientist (read : dumb guy in an apron reading someone else's report) being taken seriously after using the term "buckyballs" on TV.

Do you do everything that your grandpa did? If not, then forget the nazis 'cause their granchildren too don't do things their grandpas did. Gotcha!
There's always sufficient, but not always at the right place nor for the right folks.
Look for this to become a serious industry as techniques for creating this stuff improve and new uses are found for things. If high-tech development has shown us anything throughout history it is that as soon as humans discover they can do something, they find a reason to. Richard Smalley, one of the guys who got the Nobel back in '96 for discovering the C-60 bucky-ball has founded a company for making nanotubes cheaply. (http://cnanotech.com) I'm both anxious and a little frightened to see what science starts coming up with once it starts getting cheap to work with this stuff!

Either I don't get your 'humor' or you are plain stupid, referring to German speakers as nazi's.
Anyway, this techweb article tells you how productive Germans are in the open source world. Now it may be true that open source programmers don't make up as much of the slashdot gang as they used to, but there probably still are quite a lot of German slashdot readers.
Well done, you can now cut and paste.
For your next lesson in using windows, we will teach you how to exit programs
Move the Mouse Pointer to the Box with a cross in it at the top right of the window. While holding the mouse steady, depress the left mouse button and then release it. This will cause the window you were using to disappear. Now pickup the mouse and wrap the cord tightly around your neck. Loop the cord over the top of your chair and then fall off of it. If you have a cordless mouse this will not work, so just swallow the mouse and CHOKE TO DEATH
A molecule of C12?
A wire that could self solder seems to me would have a very low heat tolerance. My understanding is the smaller the circuit the less power and heat it would generate. How would this work? What would be the practical applications and what potential failures would it possibly create?
look at his user info and you'll see quite a few amusing posts - he invariably claims (in a very sincere manner) to be an expert in whatever field the post relates to- BlueTooth, database design, etc, with

Is "solder" that disconnects when certain voltage is applied all that useful??? I mean this would be cool if it actually stuck, but it seems like the article is treating it more like a slow switch than a building adhesive...

Why do the Slashdot editors invariably refer to it as "the fish"? Do you think it's cool or clever or something, or is there some history that I'm not aware of? I think it would be better to just call it "Babelfish"; alternatively, editors on the dot could start using coolbreviations for the soft, the hoo, the 5hin, the hat, etc.
what gives?
What's bloody new? Every new invention is first used in a military way after which it will benefit the general population. Or are you telling me you finished the Colossus before you even built one Phalanx? Huh?

I do believe Nature gets the "award" that "Dr. Evil" introduced to "us" with over-using "quotes".
'nano-computer' 'by-hand' 'self assembly' 'control'
On a serious note though, did anyone read that last paragraph? If not, I'll summarize - "Well guys, we spent millions in goverment funding, and came up with some pretty cool shizz. The only downside is, uh, it really doesn't have practical application! But hey, who cares, we've got the media giving us attention".
So this is just yet another technology that has about the technological impact on computers that Aibo had on personal pets, and everyones up in arms talking about how now the new revolution in computers is upon us. Yeah, it's great to know, but we've got a LONG way to go before this will have practical application.
Information is the catalyst for revolution
First i thought i just read another example of Monthy-Python-like-Humour. Then i read your comment again and thought: what a prick!
I wonder how nice it must be to live in a world where everyone refuses to read/buy products/books which originate from a country which, in some time in their history did something wrong to somebody else.
Like japanese people not buying products from the US because of WW2 or most of europe against the french because of napoleon.
My 2 groschen (german equivalent to cent)
Now go on and flame me for beeing a nazi or something, thank you!
Sounds like a fuse to me, which is a slow one-way (ie on->off, permanently) switch.
Does voltage cause heat anyway? Isn't that current? If so, it should all be fine, because the currents should be low anyway at that kind of scale.
Panic over, everybody get back to work.
or most of europe against the french because of napoleon.
The reason most of Europe is against the French is country-specific. The English hate them for their eternal warfare and the rest of us hate them because they hate us. The fact Chirac keeps whining about our drugs-policies might have something to with it as well...:-)

Nanites and their ability to revolutionize the world has yet to be seen. Reprogramming them would probably be a pain and the speed with which they could do anything would also be limited as well by extreme cost.
Also add to it the complete overzealous nature of the way the tech world thinks the world will come to the end via nanites will most likely prevent the average person from having any nanities at any price. This would prevent the near utopia level of living that some of these people think would happen if wide spread use of nanites would happen.

Censorship on Slashdot
So I was thinking "Of course he's read about the fish...".. given that you must have used it before and seen The Link. Oh, wait... The HyperLink on altavista's page... oops webpage which explains all about the fish .. damn .. the babelfish and its origins. it's a fish. It translates. the type of fish? Babel I guess. It's a babelfish. Calling it 'the fish' is not a bad thing. get over it.

Personaly i do like your drug-politics (i suppose youre from holland):-)
But what i tried to point out was, that in my point of view its quiet dangerous to "hate" somebody because of prejudice. I mean our friend tyronefine tries to tell me that he's hating every german (or german-speeking) because of what them fucking nazis did in the 3rd Reich.
At the same time he tries to "helping to found an organization to fight against racism in the high-tech arena". Hello? Have you seen a more perfect example of racism on slashdot in the last days then his post??
I think you misspeleld the word articulate to articualte in your USER INFO page :))

Have you seen a more perfect example of racism on slashdot in the last days then his post??
Yeah, a couple of those. They all disappeared quite quickly as either offtopic or flamebait. Although not at all perfect, the moderation system does take care of these jokers. The fact that my reply to you was a joke should be interpreted as me not taking the original poster seriously at all. Oh and yes, I am from Holland, I do speak German, and I spent the last week with a number of very nice French people.

You don`t need to read it, if you don`t understand, or are too lazy to translate it. This was the most racist and nazi-like comment I read here. As living in Slovakia (Central Europe) I know something about nazis, communists and other forms of totallity. But it is not reason to not speak German, Russian... Or what about BMW, Mercedes Benz cars - are they also nazi products not worthy to even look ak them? That`s all for today, must go

A carbon tube with a diameter of 4*10^-10m (= 0.4nm)
The Nobel Price 1996 for Chhemistry was awarded for the discovery of a soccer ball - a very small one though. The "Buckyball" only consists of 60 carbon atoms. Its synthesis and detection awarded Robert F. Curl, Harold W. Kroto und Richard E. Smalley the price.
(Download)
The atoms of this molecule are placed exactly like the sextangular leather patches of a soccer ball. With this C60 is another modification of carbon among graphite and diamond. Until now quite a number of carbon spheres of different sizes have been found. The smallest one of this Fullerenes called class of carbon molecules - the C20 - was just recently described in the magazine Nature (2000, 407, S.60-63.).
(picture)
A few years ago there was quite an euphoria about C60 and relatives, and its applications in various areas of science was lively discussed (e.g. superconduction and HIV proteasis inhibition). Even if today anyone can order C60 in chemistry wholesale shops ($500 per gramm) there never was a real technological breakthrough.
The latter is hoped to come with carbon nanotubes - molecules formed like tubes that consist exclusively of carbon (like C60). These tubes were discovered 1991 by the Japanese researcher Sumio Iijima. Nanotube research started as offspring of Fullerene chemistry and is on its best way to surpass it.
(picture)
Carbon nanotubes consist of concentric graphite shells - between one and fifty of them which gives a diameter of 1-50nm. But nanotubes can be up to a millimetre in length - and it is this anisotropy that is of importance for applications. Fibers made of nanotubes are said to have an enormous tensile strength (100times stronger than steel with 1/16th of steel's weight). The interior of these tubes can be filled with various material (e.g. hydrogen) - even chemical reactions are possible within these miniature test-tubes.
Because of teir special electronic properties these tubes could become an important part of future nano technology.
(picture)
In today's issue of Nature two research groups from Hongkong and Japan report independently about the(ir) world smallest nanotube (Nature, 2000, 408, S. 50 und S. 51). It only has a radius of 0.2 nm (nanometers, 2*10^-10m). According to theory scientists this radius is the ultimate as smaller tubes won't be stable any more.
The extreme curvature of the carbon shells creates unusual physical properties: along the axis these tubes a metal-like conductivity is postulated. Further properties of this smallest of all nanotubes have to be researched, but be prepared for suprprise.
Nanotechnology is going to destroy the pathetic United States, as well as every other country in this world? Why, you ask? Because the technology has the potential to:
1) Make humans immortal (or pretty close to it)
2) Grant humans the use of 'unlimited resources'
3) The ability to learn things much quicker
Do you honestly believe that a military or politician(s) will be able to keep this technology to themselves? That is absolutely impossible, considering the people with the real brains aren't even in the military or the government, and if the government decided to keep the technology for itself, these 'people' would just create a non-commercial nanotechnology which they would release to everyone, in the name of rebellion against a government that never worked properly or efficiently in the first place.
The United States may be eager for Nanotech, but the truth is they are also horrified of it. Why? Here is the truth that the morons in our governent don't want you to know: NANOTECHNOLOGY WILL BRING THE ABSOLUTE DEATH OF DEMOCRACY AND CAPITALISM. Wow, it looks like they have every right to be afraid. No more government - no more money system! WHAT ARE WE GOING TO DO!?
That answer is simple - we are going to become Gods, and there is NO ONE alive or dead who can stop this from happening.
'Death to the pathetic United States, and death to Democracy and Capitalism!! Good riddance!'

Censorship on Slashdot
we finally have the technology to make really easy to hide pea shooters.
The teachers arn't going to like this one bit.
One point that might be worth discussing, though, is if there's some kind of Slashdot policy regarding posts to articles in foreign languages (foreign for most of you, anyway.) Speaking German myself, I don't mind the occasional post of some article in c't magazine, one of the best computer magazines in the world. Does this aggravate people with no foreign language competence that much that this sort of post should be entirely forbidden, or should it be encouraged as being a valuable contribution to the inter-cultural communication aspect of the Internet?
As a state gets corrupt, its laws multiply; the most corrupt states have the most numerous laws. (Tacitus, Annales 3:27)
In fact, I think language competency is a wonderful thing that should be embraced and encouraged because it is one of the prerequisites of inter-cultural communication that one is able to communicate with others on their ground instead of forcing them to cross over to one's own.
BTW theAs a state gets corrupt, its laws multiply; the most corrupt states have the most numerous laws. (Tacitus, Annales 3:27)
How about allowing people to customize their accounts to not being shown non-English stories? If they miss interesting pieces of information, it is probably their own trade-off for the luxury of not being shown them.

The STM has a very fine metal tip. When voltage is applied to this tip and it is brought very close to the nanoparticles, a current flows from the particles into the tip. But by altering this voltage, the researchers were able to switch the current on and off, because their linker molecules were voltage-sensitive.
Wait a minute. You're using an STM, and you're amazed that when you drop the voltage, the current stops? Hello! The current is due to electrons tunnelling through the gap between the tip and the material. If you reduce the voltage, you reduce the energy of the electrons in the tip, and thus the probability that they will tunnel through the gap
Does anyone know if they tried applying a positive voltage of the same magnitude that caused the current to flow? If they haven't yet, I think that they would be *surprised* at the results. If they have, and there was no current, then I respectfully retract my rant.
It may look like I'm doing nothing, but I'm actively waiting for my problems to go away.

In case the post was an actual question, however, yes, it was carbon. :-)

"Schiffrin and colleagues used a class of organic molecules called thiols that stick to gold. At the end of a chain-like molecule, a thiol group reacts with a gold atom to form a strong link. Molecules with thiols at both ends can link themselves between two gold surfaces. So the team attached gold nanoparticles to a flat gold surface, tethered by two-headed thiol molecules. Each gold particle, they say, is probably linked to the surface by dozens of these molecules."
I can see it now... geek relationships of the future will forever be changed:
*geekMan*: "Honey, will you marry me?"
*geekChick*: "Oh, darling! A gold-accented iMac, with LinuxPPC, gold-thiol technology, and diamond trim! Of course I'll marry you!"
"O frabjous day! Callooh! Callay!" She chortled in her joy.
You used the word "Geek" and "iMac" in the same sentence.
I think what you meant was "Oh, darling! A gold-accented dual 1.2 gHZ Thunderbird, with (Debian/NetBSD/let the holy war begin), gold-thiol technology, and diamond trim! Of course I'll marry you!"

Once upon a time, not very long ago, you had to speak German to become anything in any technological or scientific field, because most literature, or at least the most recent literature, was in German. Only very recently has this begun to change. Especially in computer science and electrical engineering, most literature is now in English, but literature regarding chemical engineering, physics and biology is still mostly German.
Instead of whining that you have to use Babelfish, whining that everybody should learn English - why don't YOU learn German? Personally, I speak Dutch, English and German, and a little bit of French - and I wish I hadn't dropped that in higschool...
