— Purple Avenger There is nothing new under the sun. Just huge pile of old shit we haven't discovered yet.
...Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements...They go on to say that it might be able to replace Platinum with much cheaper Tungsten Carbide as a catalyst. This is pretty interesting. I'm virtually certain now that I've made these things in the lab and never realized it. It would explain a lot of unexpected results we've gotten....Superatoms are clusters of atoms that exhibit some property of elemental atoms. Former work in Castleman's lab has involved investigating the notion of superatoms. One of his previous experiments showed that a cluster of 13 aluminum atoms behaves like a single iodine atom. Adding a single electron to this aluminum-atom system results in the cluster behaving like a rare-gas atom...

Honestly, officer. I was just messing around while making Rock-Candy. Must've got some super atoms mixed in there!

Had a few of those, but no.
One example was when I was punching some elemental aluminum into SiC wafer (in a nitrogen purged chamber to prevent oxidization of the AL). Normally the resistance laterally across the surface of the wafer is in the mega-ohm range. After the process, the resistance across the surface was around 60 ohm. That was unexpected. Its almost as if I'd created a StarTrek'ish "transparent aluminum", but I didn't think I had enough aluminum there to accomplish that sort of thing uniformly.
It was transparent though, and it was surprisingly conductive...which might be useful. Maybe that process I stumbled on could replace more expensive ITO coating.

Pt catalysts are everywhere, and even in the minute quantities used in detectors and such, a cheaper material would be great. I wonder if this could tweak the reactivity, too. A really good oxygen reduction catalyst would be an enabler of a lot of technology.

I'd like to tweak the reactivity a bit to do selective hydrogenations that Pt is not doing (or not doing well). Maybe a more stable / longer living aldehyde reduction catalyst?
Looks like I've got some reading to do.

Our local materials characterization capability is very limited, since our budget is $0.00 currently ;-> The effect was noted and added to one of the patents though.

You'd probably have to create them in little isolated nano-islands...which our current lasertech is perfectly suited to doing. It wouldn't be hard at all to deposit little inert walls around the islands. We already know how to do that pretty rapidly.

Also, maybe this is one step closer to hydrogen powered vehicles becoming commonplace. Expensive fuel cell catalysts are one thing that makes them terribly expensive.

Nice link, PA. Interesting stuff. I wonder if they'll be able to create designer materials like superconducting, room-temperature rubber, diamond hard ice-crystals, or something that looks and acts like gold that is half the weight.

I have no idea what Purple is speaking about , so i turned it into something i could understand.
It was transparent though, (negligee) and it was surprisingly conductive... conducive to that which might be useful. Maybe that process I stumbled on could replace more expensive ITO (er well fill in this blank)coating

If the results cannot be extended through simple inorganic compounds (like compounds involving the alkali metals), they still might be extended through organometallics (and silicon and germanium counterparts). This should give us chemists many more low-cost things to play with. I wonder if they can come up with a dirt cheap hydrogenation catalyst to replace platinum.

What I mean is that these compounds probably won't have the same stability across the temperature range or the same physical appearance at any temperature as the metals they mimic. Tungsten carbide most definitely does not resemble platinum and titanium oxide doesn't resemble nickel. There won't be any tungsten carbide and cubic zirconia rings you can fob off on your girlfriend, I'm sorry to say.
I wonder if anyone has attempted to use WC as a hydrogenation catalyst....

First what the authors looked at was the photoelectron spectrum corresponding to electron detachment from the negative ion. The spectra are similar (but not identical) for the diatomic anion and the corresponding metal anion. This just says that the molecular orbitals in the valence region are similar. This isn't an earth-shattering discovery.
Second, the two substances will have different material properties. Nickel is a metal. Titanium oxide is not.
Third, the two substances have different symmetries. Atoms have spherical symmetry, diatomic molecules do not. Symmetry is really important in quantum mechanics. So their wavefunctions will never become exactly identical, which is what would have to happen if one substance were to behave identically compared to another.
It is an interesting discovery but it does not herald the dawn of modern alchemy.

Yep. Not to mention these molecules are, in many instances, going to be a lot larger than the corresponding metals with all that entails.
Posted by: Mike Z. at December 31, 2009 11:41 AM (JjPWh)
In fact, from an electronic perspective, they will always be larger. The size of the nucleus of an atom varies, but the total electronic space (but not the wavefunction / orbital shape) around an atom is nearly the same regardless of the atom in question.

re: 65
previously, it was called a bose-einstein condensate. but those only occur at very low temps where a cluster of atoms will function like a single one.
I may be misreading the article, but from what i gather, these "superatoms" are molecules that just happen to behave identically (thus far, only with electron removal) to an element. they havent tested chemistry et al. I suspect it wont work when it comes to chemistry, or at least it doesnt wrap around the periodic table, b/c then PbO would be just like radium.
Posted by: A.G. at December 31, 2009 11:52 AM (jBPzC)
I always thought "cluster of atoms" meant "molecule" or, in the case of metals, "alloy". Never suspected that these clusters could mimic the properties of a SINGLE atom...
Posted by: Zimriel at December 31, 2009 03:10 PM (N8KrH)
There's nothing new about that -- they're called radicals (or used to be, know they're called "functional groups"). Nitrate and nitrite, for example. NO3 acts much like a single atom in chemical reactions.I think the special deal here is that these groups of atoms mimic the electronic signatures of other elements. What's just as interesting is that the mimicry by these super atoms is predictable.
Not being a chemical guy I can't predict the implications of these critters but PA has an interesting thought about using them as catalysts. You could shave a ton of money off the price of a car by replacing the platinum in catalytic converters with something cheaper. You might even be able to fine tune them to improve their performance.
Since their effects are based on specific configurations of elemental atoms you won't be able to react them with other stuff to make new wonder substances, I suppose. But, then, who knows. Maybe PA will be the first person to build super atoms from chemical compounds. Sounds like right now you could mix them with other goop to make something with physical properties presently unobtainable. I predict their first uses will be in nano-tech, however, either herding those pesky little atoms into do things they refused to do before or doing what is done now cheaper and on a larger scale.

For the work I've been doing, this is the most interesting part. It means we might be able to dope with something cheaper than certain expensive hard to handle pyrophoric metalorganic gasses and still get nearby covalent/trivalent bonds in the resulting lattice to behave the way we want them to.

So does that mean these super atoms are useless for nano tech (can't be used as substitutes), or does it mean there's another tool in the drawer -- even if we're not sure how to use it?Posted by: Tinian at December 31, 2009 12:08 PM (7+pP9)

There's a lot you can do at the atomic level without needing QM effects. The biggest problem is probably going to be sorting the wheat from chafe after they're created and getting a pile of wheat large enough to be useful. Atomic level sifting is hard.

Even that can be useful. With our lasertech we've created and sort of "flash frozen" such exotic materials into states they wouldn't otherwise be happy staying in. There's quite a bit of stuff you can make with nano-scale processing that simply can't exist in the general universe where heating/cooling effects are of necessity macro-scale. Extremely fast heating/cooling allows for some interesting stuff to happen.
