Search for Ultra High Superconductivity (1200K)

It's from this guy:

http://www.calstatela.edu/faculty/gzhao2/

It seems he published a lot of articles in respectable magazines. I'd like to know what are the opinons of you people.

He hosts a list of preprints for his articles, and you can freely look at them and analyze

If he is a crackpot, it's nice to denounce him, since he publised way too much in important magazines.

I wouldn't say he is a crank - he says he is researching the possibiity of an effect not that there is one.
Based on nobody having much idea what causes ht super conductivity at any temperature and nobody knowing al the properties of things like carbon nano-tubes it's probably worth a try.

But, as alxm says - you want to be REALLY sure of your results before you announce it!

Well, he's not a crackpot at all in my definition of the term. (I define it as the category of people who've done no real work at all, whereas those who've got crazy ideas but still have done real work I categorize as 'misguided' at worst)

Seems like he's doing mostly legitimate work in solid-state stuff. Although that's not my field so I can't criticize it in detail, most of it looks quite sane enough. Obviously superconductivity at 1200K is a pretty fantastic claim, but I don't seem to see any papers claiming to have done it. More like, things which he thinks might indicate the possibility of it. (Regardless, I don't think the mainstream will ever believe in superconductivity at 1200K until it's been experimentally verified!)

I guess I'd summarize my impressions as that it's a researcher who's a bit on the speculative side, but well within the limits of acceptable behavior. (although I'd be more prudent) At least as far as his peer-reviewed stuff goes. After all, you're not supposed to believe in other people's speculations anyway. Just the results, ma'm.

There are some circumstantial evidence that the centre of neutron stars are condensed fermion systems, or at least have non-classical inertia. It turns out that we can measure the rotation rate of neutron stars well enough to see quantised vortices leaving it.
