Thanks for that. Feedback from my friends in the semiconductor business
one of whom did his PhD on high temperature (LN2) superconductors is
that until another group confirms they can make it and observe confirmed
characteristics of true superconductivity the claims are highly dubious.

Possible theoretical support (above) is interesting. It is just possible
for some x and some exact topological configurations it really does
work. I\'d expect some of the better superconductor research groups to
get samples to test if the recipe is genuine within a couple of weeks.

One former colleague basically said:
\"At times like this a look at Irving Langmuirâs talk on pathological
science is always a good idea. There seem to be a few of the signs he
mentions here.\"

https://en.wikipedia.org/wiki/Pathological_science

IOW pretty much like Blondiot\'s N-rays.

Unfortunately Korean scientific research groups have form for making
dubious claims so it doesn\'t surprise me that it has failed.

OTOH there is still hope that a material made with exactly the right
doping might have at least some interesting properties at STP even if it
isn\'t actually a proper superconductor.

I found the graph of resistivity vs temperature very odd indeed YMMV.
Although I fail to see how a 4 point measurement scheme can work on a
polycrystalline material with 1D superconductor characteristics.

For now I will give it the benefit of the doubt but still with my very
sceptical hat on I expect one of the bigger superconductor research
groups to either verify it or refute the claimed properties within the
next couple of weeks. Pathological science seems an apt description.

If the Korean research team wants to be taken seriously now they will
have to hand over one of their samples to an external independent
testing lab with the right kit to determine its actual properties.

I think you will find that Hell freezes over before that happens.

No other laboratory has been able to replicate the material or see
anything that looks remotely like superconductivity. Even the graphs
that they published show some finite resistance when the stuff was still
supposed to be superconducting. Diamagnetism != superconducting

A lot of fuss about some impure messy diamagnetic copper sulphide and
questionable experimental techniques that should be consigned forever to
The Journal or Irreproducible Results.

Pity- it would have been very nice to have a superconductor that worked
at STP even if it could only tolerate low currents and magnetic fields.

For comparison with the Korean \"publication\" on arXiv here is an example
of a real superconducting experiment on iron sulphides with graphs.
