This stuff is the materials science equivalent of making a baking soda volcano, in terms of difficulty. If their results are BS we will know quite quickly. I have no doubt people are attempting to reproduce their results right now. If they wanted to get the credit for a BS discovery they definitely could have picked something harder to reproduce. They're making a very easily verifiable or falsifiable claim.

That's a good way of putting it. If you are a fraud, why make it so easy for someone to call your bluff.

The instructions they provide in the paper seem fairly straightforward and reproducible, I'd expect that if this is in fact legit, there will be many attempts to replicate the result quite quickly.

Thanks for commenting, as I'm not qualified to evaluate this. Authors providing such instructions should be commended, even if their result turns out to be false due to errors in measurement or interpretation.

Let's hope so. The easiest way to convince the world that you have a room temperature superconductor is to make up a big batch of samples and offer to distribute them to national labs for testing. First test, does it levitate a small permanent magnet, demonstrating diamagnetism?

They have photographs of that on page 7 of the sister paper: https://arxiv.org/ftp/arxiv/papers/2307/2307.12037.pdf

Would love 3rd party confirmation as well, of course.

Thanks, I was looking for that video that was referenced in https://arxiv.org/ftp/arxiv/papers/2307/2307.12037.pdf

It's unlisted as well but published back in January of 2023. I wonder what they are going to think with the influx of views on it, (43 views as of this post)

Is it just me or is it odd not seeing the normal condensation of the surrounding air due to a chilled superconductor like you get with a YBCO.

Partially levitating on the magnet seems kinda convincing. None of those materials would do that on their own.

They wrote the recipe. It looks like it's easier (for people that has a similar lab) to make your own instead of filling all the import reports to get one.

Some superconductors get destroyed by humidity, so it may be difficult to ship them.

If nobody can reproduce them, then they can send samples or travel the word making samples on site, or receive researches to train them.

The good part of publishing the recipe, is that other people can make small variations. If this is true, there is just now a big race to get a higher record temperature.

This comes accross as very passive-aggressive.

Researchers come to a conclusion and make a paper, this is exactly how it is done.

Others can try to replicate their results, the paper is very explicit with what they've done.
