High T Superconduction Solved!

Now, Pablo Esquinazi and his colleagues at the University of Leipzig report that flakes of humble graphite soaked in water seem to continue superconducting at temperatures of greater than 100 °C. Even Esquinazi admits that the claim “sounds like science fiction”, but the work has been published in the peer-reviewed journal Advanced Materials, and other physicists contacted by Nature say that the results, although tentative, merit further scrutiny.

Wow, cool....no wait, err NOT cool.

I'm thinking water pipes with graphite running down them could deliver both water and electricity to consumers.

Awesome (if true)! Here's to the future energy security of China, which has loads of graphite :cheers:

Sounding a bit like the cold fusion debacle. I'll hold my excitement till there is independent verification.

Byofrcs, that might work, but it is nothing like the cold fusion technique found to be flawed:

Failing that, you could just make it disappear. :awesome:

That beith the one I speakith of.

Byofrcs example is a hot fusion example, albeit still exciting if they actually do get past the break even point.

It is equally exciting, for all practical purposes. All that is required is that the energy generated by the process be greater than the energy used. When that happens, the net energy generated rises exponentially. There is no additional benefit afforded by being able to carry out fusion at room temperature.

The record for high-temperature superconductivity has been smashed again.


Lanthanum hydride LaH10 @ 250 Kelvin (47 K warmer than previous best). No Mesiner effect (exclusion of magnetic fields) yet because the sample is in a diamond anvil at 170 gigapascals pressure but the zero electrical resistance is observed and the critical temperature is seen to decrease when the hydrogen is replaced with deuterium (as expected).

ETA Also @ arXiv link

Also text correction. decrease :doh:

Meanwhile, back in the graphene camp:
Discovery of ‘magic-angle graphene’ that behaves like a high-temperature superconductor is Physics World 2018 Breakthrough of the Year

13 Dec 2018 Hamish Johnston

The Physics World 2018 Breakthrough of the Year goes to Pablo Jarillo-Herrero of the Massachusetts Institute of Technology (MIT) in the US and colleagues for making the discovery that led to the development of “twistronics”, which is a new and very promising technique for adjusting the electronic properties of graphene by rotating adjacent layers of the material. The technique was first used by the team to create “magic-angle graphene”, which behaves like a high-temperature superconductor.
