I only need a thumbnail size specimen:-D

I have a list of things I can trade...

Actually you can collect them, just not in a concentrated form. Finding information on Shungite that hasn't been vomited out by the crystal-healing people is pretty hard, but I am pretty sure that they are fullerenes in it- Mindat says it in the listing, but it's unreferenced. Maybe I'll look for one later.

There are two qualities of shungite available
One that looks black matt that can be polished and high grade metallic luster material
Is is found in Karelia north of St Petersburg
both types are composed of fullerenes (buckmeister balls )! geodesic balls of carbon atoms referred to as Bucky balls
The geodesic houses were designed from these structures .

Tom, I am not sure if you are aware of the rules here, but you are not allowed to sell anything. I am glad that you have good-grade Shungite for sale; it is very interesting material. And actually, the "Buckyballs" were named after the geodesic structure, not vice-versa. Buckminster Fuller (fullerenes were also named after him)- existed before the fullerenes were known.

Buckyball...
Isn't that what they play at the University of Wisconsin - Madison on Saturdays in Autumn??? :-D

Old news being recycled in the dog days of Summer I think. The Russians (and some others) were scratching Diamond with a Fullerene (C60) tip of prescribed dimensions back in the '80's and have been ever since. Last time I looked, there were three substances known to be harder than Diamond and a couple more whose superior hardness has been theorised but not yet demonstrated.

Only with the advent of Fullerene, was it made possible to measure accurately the hardness of Diamond. As Diamond cutters have long known (but could not quantify), the hardness of Diamond varies according to the direction of the cut/scratch though they had no way of accurately quantifying the difference. For those addicted to thinking of hardness in terms of Mohs's scale, the following factoid may be thought-provoking.

Depending on the scratch direction, the hardness of Diamond varies by up to 30,000 GPa (GigaPascals). 30,000 GPa is approximately the properly quantified hardness of Corundum. Accordingly, the variance, in measurable Diamond hardness with the scratch direction is, in reality, a little greater that the difference between the hardness of Corundum (Mohs 9) and Talc (Mohs1).

What exactly was the guide's expression when he saw the mermaid in the movie "Splash" This would have been at the Statue of Liberty. I thought it was something like "Buckyballs" but am not certain about it. It was a very funny movie.

(I think it's more Ohio-Columbus than Wisc-Mad, having had relatives gone to both-that'd be badgerballs ;) )

It was "BOCCE Balls," and that movie was terrible. I seem to recall Tom Hanks was in it, but either way it was a pretty bad waste of his talent...

Well... some time later and fullerene isnt only fun experiment but it is going really strong in many areas. Coating, lubricants, metallurgy and many more. Bucky balls in general are very interesting. Have you ever read about that mice experiment when the group of mice lived twice as long after digesting bucky balls? Iam really looking forward of future research on that one. :)

For anyone particularly desperate to see fullerenes in person, they form a significant proportion of the brownish, flocculent soot that you sweep from a solid fuel chimney.

Unlike the laboratory grade material, these are a mixed bag of outsized fullerenes whithin which are nested all of the smaller spheres that will fit, along with a variable amount of graphene and bitumens.

There is some indication that the charcoal horizons (the remnants of forest fires) found in a number of rock strata contain soot-type fullerene balls.

If I'm correct informed, fulgurite can contain a little amount of fullerene.
