I am totally confused, it is documented in the original south korean paper, why anyone would want to rely on such second hand unverified info when first hand info from the original inventors are freely available to everyone?
not sure what you are saying. other labs are trying to replicate what Koreans published and are documenting the their process of replication
This makes me extremely bullish about Varda Space, they have engineers of high quality and expertise that they could do a decent replication very quickly (if they got access to raw materials earlier, they might have been first to do so, comparable with the Chinese Groups) while working on their off time (from what I’ve seen of their twitter) and not a single big academic lab has managed to complete any sort of replic…
World first replication was done by Iris Alexandra using her own accelerated process and there is no way Varda Space could have beaten her.

Do we actually know who that is though? I thought it was pseudoanonymous. It’s a new twitter account at least.

It's really disappointing that no other US lab has engaged with the public in the same manner. Regardless of the outcome, I think seeing things get built and experimented with in mostly real-time is a massive source of inspiration.
All I see from US academics on Twitter are debates about this and that. Borderline annoying. This is the first result from mighty US capitalist machine meanwhile 3 Chinese labs have published pre prints and Russian replicated it in her kitchen.

The first pre-print came out on 22 July (if I am not mistaken). Not enough time has passed pure and simple. If I was an academic working on this, I would be following the Sagan Standard and triple checking my results before claiming anything. I think we are all suffering from 24 hour news cycles. The work in China and now Varda is very exciting but they are warp speed developments.
This is simply what post-peer-review looks like. Instead of a few anonymous peer reviews, you get the entire planet to replicate. Moment you get something meaningful, publish it on arxiv. Quantity, not quality is king. Anomalies are drowned out by large samples. Questionable methods get mass debated in public. Scientists are dependent on public funding, why squander the biggest moment in pop science for literal decad…
- ordinary ppl more or less understand the importance of RTS
- a visible and understandable effect (Meissner) can be shown on successful replication
- the materials required are easier to understand, but the synthesis procedure is tricky, and purity is important
- The skills of chemists comes into play, leading to kind of a Breaking Bad feel
The humility is refreshing, compared to anime girl. Also, the photos/videos are not shot using a potato.
Can anyone conduct a proper measurement of resistivity versus temperature and determine whether it's a superconductor or not?
Unfortunately such measurements are not enough for definitive conclusions, because all that they can show is that below some temperature the resistance becomes smaller than the error of the measuring equipment.
Moreover, because the samples obtained so far are extremely inhomogeneous, they do not show a definite transition temperature, which would have made superconductivity much more plausible.
In any case, the results obtained so far are enough for showing that it is worthwhile to invest time and money for developing a method of producing samples that are larger and more pure, because whatever they are, they must have unusual properties.
The best would be to develop a method for making monocrystals, because this material has an asymmetric crystal structure, which might have very anisotropic properties.
The most interesting properties of semiconductors could not be discovered during the first century after their discovery by Faraday, because they were not available as pure monocrystals. Only after the methods for growing pure crystals have been developed during WW2 (for radar diodes), it became possible to measure the intrinsic properties of the semiconductors and to design new devices using them, and then the semiconductor industry has grown exponentially.
With this kind of non-metallic superconductor, the problems may be similar.

Naturalize the Russian, problem solved.
