I have to throw out a question.
How do you contain fluoroantimonic acid?
Some say polyethelene bottles, others teflon but I am not satisfied with the source I heard this from.
Are there any experts that can answer this?
postìng now so i can come back later. Great thread, i didnt know that these substances even existed. And here i was getting exited aboup Aerogel...
It also seeps right through otherwise solid materials

1. The Most Super Superfluid
Superfluidity is a state of matter (like solid or gaseous) that occurs at extremely low temperatures, has high thermal conductivity (every ounce of it is always exactly the same temperature), and no viscosity. Helium 2 is the “most” example of this. A cup of He2 will spontaneously flow up and out of a container, as if it just decided to leave. It also seeps right through otherwise solid materials because its complete lack of friction allows it to flow through otherwise invisible holes that would not allow regular helium (or water for that matter) to flow through. He2 did not wind up at number 1 just because of its ability to act like it has a mind of its own, though, it is also the most efficient thermal conductor on earth; several hundred times that of copper. Heat moves so fast through Helium 2 that it moves in waves, like sound (and is fact known as “second sound”), rather than dispersion, where it simply transfers from one molecule to another. Incidentally, the forces governing He2’s ability to crawl walls is called “third sound”. You can’t get much more extreme than a substance that required the definitions of 2 new types of sound.
There is little chance of creating a soup of superfluid neutrons on Earth. Although particle colliders can create dense fireballs of matter, the temperatures are too high to mimic the interiors of neutron stars. Superfluids made in laboratories are usually composed of chilled helium atoms.
On Earth, the appearance of superfluidity in materials occurs at extremely low temperatures, near absolute zero, about minus 273 degrees Celsius (minus 459.6 degrees Fahrenheit). But in neutron stars, it can take place at temperatures near 1 billion degrees F because interactions of particles occur via the strong nuclear force — the force that binds quarks together to make protons and neutrons, and protons and neutrons together to form atomic nuclei. Until now, there was a very large uncertainty in estimates of this critical temperature. But the new research pins it down to between 900 million and 1.8 billion degrees F (500 million to 1 billion degrees C), researchers said. "It turns out that Cas A may be a gift from the universe because we would have to catch a very young neutron star at just the right point in time," said Page’s co-author Madappa Prakash, from Ohio University. "Sometimes a little good fortune can go a long way in science

when i heard about graphene about a month ago i had to find out how i can invest in it. its ticker is cvv and im happy i read the likes of gizmodo,sci american, pop sci; because it has been a good position. i tried finding out about commercial applications for the adnrs' but had no luck. also im very interested in the magnetic properties of the substance u mentioned. i think the coolest of the 10 would have to be the super fluid.
