Nano Logo
leb writes "More useless but fun innovations in nanotech - University of Massachusetts physicist Mark Tuominen may have some trouble finding a T-shirt small enough for the UMass logo recently sketched in his lab. Tuominen and graduate student Mustafa Bal recently created a UMass logo which is roughly the size of a red blood cell - some six micrometers in diameter. Full story and images available from the UMass News office."
Hey, who would have thought that two people could possibly think the same thing was interesting? I'm interested in nanotech, too. That's why I posted the story.

Actually, both these thoughts ran through my mind until I read the blurb. And I was still mistaken when I hit the link for the pics. I thought I was going to see the coat of arms of UMass.
Achieving that level of detail in 6um would have been really impressive!
Ahh - My eye!

nanoo, nanoo!
Since I first saw it I have been impressed by the picture of IBM written in Xenon atoms on Nickel.
Now, as the era of nanotechnology gets nearer and nearer, I would like to have a poster sized copy of this for my wall. Anyone know where I can get this (or any other STM pictures or photomicrographs)
Anyone have any pointers to good companies to invest in to get in at the start of this technology?
The prime ones would seem to be the likes of IBM, Motorola, biotech companies like Genentech and Celera, but who else? Unfortunately Zyvex are not a publicly traded company.
How would you know you didn't lose it? ;-)
So how long until think geek will carry nano logos of tux on a necklace?
Who cares about logos? I want some nano LEGOS!
Ok, so how long til I can write my own tiny little logos with a $250 printer?
It's great to see Mark Tuominen getting such good press. I had a class with him as an undergraduate and I worked in his lab for a summer. His Mesoscopic Physics lab is a great place. There is always a good group of graduate and undergraduate students working on interesting projects. The thing that makes him stand out from some other researchers, though, is the attention he gives his undergraduates. The synergy between these different areas (undergraduate, graduate, and research) is a great example of how education at a University is supposed to work.
Damn, misread the headline. And here I was thinking, "Great, now I too can get in on this nano-technology and build cool stuff!" Oh, well.

IBM has done some really neat molecule size atomic artwork. They figured out how to move atoms with a Scanning Tunneling Microscope (STM) and then arranged them on a substrate to write the IBM logo, among other things.
Forget the IBM logo, that's just art. Look instead at the quantum corrals. I'm teaching quantum mechanics this semester and used two of the images since they are perfect examples of a 2-D particle in a box, one of the simplest QM systems you can solve analytically. The second of the images is so good you can even tell the quantum state of the electron. (nx = 3, n5 = 5)

Was the nano-guitar built for mini-elvis?

6 microns across eh? What about 0.18 micron
Look at the resolution, easily 30 to 100 across.
That would make it about 0.06 to 0.18 microns per dot

I always hated this scene becaue I thought is was a silly idea. Now reality has caught up with it.
Like in the movie, artists, painters etc. can pour a bag of nano logo particles into their paint to mark their work. Print the lot number onto them and dump them into the chocolate bar you are producing, so that you can trace back even the slightest amount of it back to its origin. Mix nanologo particles into a car's paint so that the serial number is everywhere on the car, not just imprinted into the engine block. Mass produced nano logo particles could be used to make dollar bills, ID cards etc. harder to falsify. I'm sure there hundreds of ideas more what you can do with it, besides making integrated circuits.
Yes, you are right there. -- Another glass of champagne?
Does this mean that to be good at nano tech the organization you work for needs to have a very simple (or maybe a very complex) logo. Just think of all those great scientist who work for companies with photographs or similar for logos - looks like they will have to wait a while for the right technology to come along.
Thought it said 'Nano Lego'. Now -that- would be cool :)

RTFA, This is completely different.
The IBM logo was done by pushing the atoms around. This is more `automatic' and suited for mass production. Sure, it isn't the smallest ever, but this is another step towards functional nanotech.

The now-empty channels show up as orange areas on a yellow background. The UMass researchers have successfully filled the holes with metal, a major step toward creating usable electronic devices.
Maybe someone can explain this to me, but the fact that they can fill a very inexact mold with medal really doesn't show me that they are close to producing electronic devices. The individual partitions of the mold seem to be of a fixed shape, so the ability to cast exact electronic parts seems to be very limited. Could someone please tell me how far away useful nano-technology is? How far away are we from being able to duplicate the power and functionality of a cell? When will we have the most hyped use of this new class of devices, nano-sized robots that can do custom drug delivery? It doesn't sound like we are even close

It is not the size of the logo that's impressive here, it's the resolution. The polymer they used is the key factor behind this - if the grains of the material that they expose to e-beam lithography are small enough then the resolution will be high.
The polymer they talk about seems to have long chains standing out from the surface, each forming a very small dot that can be exposed. Pretty neat.

While I totally agree this isn't really worthy of the tag "nano" it does have some similarities with what Drexler's vision is. The logo was made from custom-made polymers which had certain properties which allowed them to self-assemble into the required shape. I think that's why this is being pushed as nano, but maybe I'm just reading more into this than whoever wrote the article. Probably - "hey it's small, it must be nano!"
Is the first thing anyone ever does with this sort of fancy new technology is to create a fancy little logo? I mean, you'd almost think they were actually frustrated artists :) This must have taken far longer to do than just a simple pattern or whatever. Maybe the extra grant money from the US government means we'll be seeing a whole load more minature pictures...
Didnt IBM commit the first act of atomic vandalism? Years ago i say a story on this, with B&W images of an IBM name appearing as peaks on a stark background... Ahh well. Let UMass have its glory, but Big Blue did it first. "One day the world will need only five atoms, and only the worlds richest five atoms will be able to afford them".
I seem to recall a couple of years ago in New Scientist that IBM (or some such company) had successfully created a nano-engine. The point was that the scientists had decided to use steam power because it was more efficient at such small sizes.
They used a tiny spot of water, which was heated and then this produced work (perhaps pushing a piston?). Has any more information been published?
As for practical uses of this, I think that real-life applications of any nano-technology are many years off!

Didn't IBM write their logo out in dot-matrix, where the dots were atoms? I think that was five years ago too. Unfortunately, I don't have the link. It wasn't very exciting then either.
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
Theught it was abeut minituarised Lego.
New, that weuld be kewl;)
6 microns across eh? What about 0.18 micron (and upcoming 0.12u) wafer fab technology? What's the big deal?
stty erase ^H
I also just looked up that Heinrich Rohrer and Gerd Karl Binnig won the Nobel Prize for Physics in 1986 for the invention of the STM. They were working for the IBM research labs in germany at the time.
Is it just me or does it bug anyone else that they wrote that it was "6 micrometers". 6 micrometers all lined up next to each other would be pretty big...6 microns would not.
Yeh, thats the 1st thing I thought. It would be an excellent idea, make a nanotech turtle.
Or maybe one that could understand postscript would be neater...

No, I saw the words "Nano Logo", and thought that Hemos wanted a new logo for the nanotech postings. I was almost aiming for the Gimp until I read the rest of the letters in the story... And it wasn't even posted by Hemos.
no seriously, I'd manufacture one nano-logo and embed it in say a 3" cube of clear plastic, maybe visible with a certain power microscope - and sell 'em in bookstores maybe with a little booklet about nano-tech - hey, if people bought pet rocks and chunks of the Berlin Wall....

You can check some out here. There are also tons of other pictures there with some short explanations. Definitely worth a browse.
Scuttlemonkey is a troll
Blah. Am I the only one who thinks at this very moment K. Eric Drexler is coming down from Cambridge to kick the asses of the whinies from UMass who are misusing his pet phrase, "nano"? This doesn't seem particularly useful or innovative. Especially considering that there already exists 0.11 micron etching technology, by traditional means. Now, the day I hear about an UMass logo 0.11 microns across, then I'll be impressed.
To the editors: your English is as bad as your Perl. Please go back to grade school.
You already can. Microfiche already has the capacity to do that, and that's nowhere near the highest density available.
How about a bunch of nano-turtles pushing bits around on a chip (literally), following LOGO microcode, emulating an 8088? That'd be a kick.
Sorry, I get a kick out of perverse forms of computation like that... Someday I'm going to build a web server that runs on marbles...

Now what would be neat is if I could get the entire last year's slashdot headlines in the palm of my hand... with all comments ;-)

This work should take about five years to finish due to the average being dragged down over the last few days.

WHAT!?! They got a LOGO intrepreter to interact with a nanotech device?!?!
Could you imagine the little bugger thinge booping around to some logo commands? Whoops, did I just put that one up your nose?
