In this article the numbers of temperature isn't mentioned. It is not exactly room temperature because is around 125° C. But yes this is real high temperature superconductor material.

Haven't seen anyone replicate the results yet but it already seems very impressive in the video

It's not yet peer-reviewed. It's scientific articles such as this that can be misused to give 'science' a bad name. Science requires a robust peer review, and replicable results, so it's not worth reporting on. Scientists are clever people, mostly, but they're still humans subject to human traits. This is why it's important to validate claims, or at least have a majority consensus accept the results by way of replication, and not being able to disprove the results.

This. There are a lot of questions and concerns around LK-99, especially since all the claims made to this point about discovering a room-temperature superconductor have been easily-disproven BS. Scientists around the world are at this moment rushing to attempt to replicate these results, which is going to take time.

Waiting for my levitating superconducting popcorn to arrive via teleport!

 

[Chry]

Someone please let us know when someone reproduces the results. Heard it might take a few days. Will put this thread on watch.

It actually looks quite easy to make and from basic available elements so hopefully not too long.

Is this South Korean?!

Because to me it's not even news if it's the other "we've landed on the Sun" Korea

Nvm Seoul, the article I read yesterday didn't note this.

And there are, unfortunately, far too many charlatans claiming to be scientists. This is evident from the rejection of the previous claim to have discovered room-temperature superconductivity and the failure of anyone claiming to have invented cold fusion to demonstrate a working device. Plus Korea has had a, shall we say, torrid relationship with scientific truthfulness.

 

[Shrek]

Yes, Cold fusion was a sobering lesson.

 

[ExcuseMeWtf]

I'll just drop in someone more knowledgeable than myself weighing in on this:

 

[Tahagomizer]

As of today it's still not officially replicated by other scientists. However, if true, it would easily be the most important discovery in history, so it's not surprising that no one wants to rush things.
Some of what they show looks suspect, similar studies in recent years have been proven to contain falsified data and consequently were retracted by Physical Review Journal and Nature, so it's important to keep a high level of skepticism. Extraordinary claims require extraordinary evidence and this evidence has not been shown yet.

 

[Shrek]

Very important yes,

'easily be the most important discovery in history'

I don't think so, but Nobel prize level yes.

I am a retired scientist with a specialty in nano characterization and Analytical Chemistry. I am also a co-author of over a dozen peer reviewed publications.
However to make a valid scientific claim you must be able to publish and reproduce experiments etc.
As soon as I saw all the social media postings I sense something is fishy. The posters claim magnetic properties, a superconductor excludes mag field lines not repel them. (Meissner effect)
l also question the 10% mixture, what about the composition of the other 90%? Lead is on the EPA hitlist as a cumulative toxin, it will be outlawed.
I have heard claims like this from fusion to graphene. Seeing is believing folks and mass production is another fantasy.

 

[TumbleGeorge]

Type II superconductor show same kind partial levitation. Is possible to be these case?

I don't think people are going to be eating superconductors.

 

[Shrek]

The EmDrive claim didn't do well
Newly-Created Device Defies Isaac Newton's Third Law - Dual Dove

I recall doing a back of the envelope calculation of forces from the currents in the Earth's magnetic field and finding this could account for what was measured.

Lead is on the EPA hitlist as a cumulative toxin, it will be outlawed.

We still have lead acid batteries and I assume it is still used in radiation shielding.

 

[Assimilator]

Neither of which have the issue of being consumed by humans either!

No, but look at Michigan water poisoning and solder containing Pb is banned in certain states.
Lead paint bans I used to manage an IH company, if paint chip containing Pb was confirmed it was a nightmare.

 

[Shrek]

I seem to recall being told that half of the electrical power to Tucson is lost in tramsission; we are not going to reject a lossless transmission system due to lead.

 

[TheoneandonlyMrK]

I wouldn't get too hung up on the chemicals use.

The whole science of how the super conductivity is establishment is new, and the theory for how and why it works is new, it too can be applied to other molecules
I thought that's the debatable point, because they're using new science to create cooper pairs.
And are not doing it the way everyone else was trying.

That's because 100+ years ago, the country didn't know lead was toxic. So we built a lot of water-pipes out of lead and then people drank out of those pipes. Oops.

Today, we have 100+ year old infrastructure in need of replacement. For now, its "easier" to just add more chemicals that prevent lead from leeching into the weater, but when those chemical balances go haywire... well... we all know what happened there.

Anyway, lead paint and lead pipes are on their way out. Lead-Acid batteries? Nah, there's plenty of more toxins available in your car or other machinery that's well known. SLA-batteries in particular are wrapped in plastic to prevent the lead from leaching out. Furthermore, Lead-Acid remains one of the few, truly recyclable batteries in our country. (Li-ion isn't recyclable yet in practice). The battery should be safe, I don't see any problem with it personally (sure its old, but it works so well)

On the superconductor issue: I'll wait for replication. It sounds like Argonne national labs (https://www.science.org/content/art...m-making-news-here-s-why-experts-are-doubtful) is trying to replicate, so this claim has gotten the attention of some of the best scientists in the USA.

Lets give Argonne National Labs a few months (maybe a year?) on attempting to replicate the experiment. If they can't do it, no one can.

Norman predicts: “If this is real, we’ll know within a week.”

Or apparently, we'll know in a week or two, let alone a month. I didn't realize how "easy" this problem was. I guess what's why its gotten so much attention, because it looks simple and obvious?

 

[LabRat 891]

Other papers on the topic, later proven to be fraudulent, have 'gifted' this topic nearly the same level of implicit scepticism as LENR/'not hot' fusion. That's why this isn't 'getting the rounds' one would have expected.



From the video-overview I watched, calling it 'truly' a room-temp ambient-pressure superconductor, is a bit of a misnomer. (Also, the definition between Academia and Public/Colloquial, differs).

If true, this would be be a metamaterial
(an artificial material, exhibiting properties not found in nature).

According to the critical current, temperature, and pressure results in the paper, this technology appears to have immediate applications in microelectronics (especially 'passive' IoT devices) and nano(bio)technology.

Personally, I'm leaning towards this being either 'true' or 'conceptually true' ie, semi-reproducible.
TBH, the claims do not seem 'too good to be true'; this isn't Space Magic, it has limitations.
(Also note that just because it 'seems too easy' doesn't mean much.
Example: Graphene has been incidentally produced (at least) since the use of Carbon Arc Lamps. Yet, PVDing Graphene is a highly-controlled and technical process.)

I don't think people are going to be eating superconductors.

Note: 98.6F is about 310K, well within the reported 'operating range' of LK-99.

You realise a famous scientist killed more people then anyone else by prooving leaded petrol was safe.

It wasn't, and upto the age of 20(I think I mean f#£# when was that) I could put it in my car.

If the proposed compound will work as intended, it will be be revolutional despite having toxic lead.
And also if this compound works, hundreds of university labs around the world will search for different compounds with similar qualities and will be likely to find them soon after.
