lol yes

But he already did a Korean science scandal 😂

Bro fr. Those are great videos.

Anton Petrov just released a great video on the current status of the various LK99 research projects.

First thing I thought of when I heard about the announcement.

69. Nice!

Hello, fellow Materials Scientist! :D

I'm homeless and I approve this too

Agree, he really outdid himself with that one.

The crazy thing is, he does it over and over again in many different topics to such detail and quality. And in such a short amount of time.

lmfao

Simply place the room on Titan.

i think my office at work is cold enough

my computer lab back when I was in university, maybe that would work

he should make Bardeen prize for people that alredy have one Nobel 😁

If anything, the MRIs need superconductors even more than before, Some newest models can handle 7.0 Tesla. I can imagine the electrons behaving more like a fluid or gas with such high currents flowing through such small cross section.

@geneballay9590 "normal, full time, permanent job" 🤣 I'm in a completely different field but I followed the same path. I had enough after MSc and didn't want to be institutionalised.

​​​@@liammhodonohuelmao, same this is why i'm joining the military and then doing horticulture, physics is great, but peace of mind is better.

@@TS-jm7jm how far are you into joining military? I nearly joined. The direction of travel didn't sit right with me. Still doesn't. In the words of smedley-butler, war is a racket.

@@liammhodonohue im about 2 months away, i just need to get a handful of documents settled and i should be good, yea i know war is a racket, i'm not really going for principles so much as i think it's a great chance to learn deeply discipline, command, logistics and i guess more indepth as to how people can mess up organisations, these are all things I'll need in the future, because after the military I'll do horticulture and/or forestry, i want to go into farming in zimbabwe or zambia(zambia looks a lot better as a prospect), i think there's a future in thoe places for farming, more in zambia than zimbabwe, but hey within a decade a lot of the ruling elite should be dead or deposed because they are too old to manage their affairs, so the future looks better even if it's not at all good now.

My thoughts exactly.

It really does have a strong wiff of cold fusion.

IIRC one institution in China reproduced the results. An American national lab verified the qualities in simulation but they predicted the yields would be very low. So far the authors of LK-99 have been open with their data which gives me hope.

The comment I was looking for, right at the top! 😅✌️😎

@@guitarazn90210 Several laboratories have made the compound according to the published recipe, but none of them, including the one in China, have shown that the material is a superconductor. A reputable laboratory in Korea has received the samples from the original authors a month ago, and they still do not know it is a superconductor. The jury is still out.

"Most ceramics resist the flow of electric current, and for this reason ceramic materials such as porcelain have traditionally been made into electric insulators. Some ceramics, however, are excellent conductors of electricity." "Electric conductivity in ceramics, as in most materials, is of two types: electronic and ionic. Electronic conduction is the passage of free electrons through a material. In ceramics the ionic bonds holding the atoms together do not allow for free electrons. However, in some cases impurities of differing valence (that is, possessing different numbers of bonding electrons) may be included in the material, and these impurities may act as donors or acceptors of electrons. In other cases transition metals or rare-earth elements of varying valency may be included; these impurities may act as centres for polarons-species of electrons that create small regions of local polarization as they move from atom to atom. Electronically conductive ceramics are used as resistors, electrodes, and heating elements." Try next time google the topic of your comment first...😅

​@@Bialy_1beat me to it, I thought everyone heard of ceramic resistors.....

And there's Italian-made BCS walk-behind tractors! 🤠

Did you know that you have rights? Constitution says you do!

They're available on KZfaq: kzfaq.info/get/bejne/gMmgpbuU0Mmropc.html

There's already levitating diamagnetic materials such as pyrolytic graphite, so it's not completely new

“I think it may simply be extremely diamagnetic (but not perfectly so), however this is obviously very interesting in and of itself, and yes pretty exciting.” I mean a relatively diamagnetic material at roughly -165C isn’t actually very exciting.

@@MonoPrime Why do people insist on replying on this site with the absolute dumbest takes imaginable? It IS exciting when it's at 20c and made of a lead, copper and oxygen ceramic. Nothing else like that is known to exist.

@@Muonium1 This aged fantastically! Pretty clear that it’s an un-scientific pre-print that was misrepresenting results of the experimental evidence.

I wonder what VIPER stands for, maybe Very Inexpensive Pipes Electrically Resistance-less

@@Special1122 stands for Vacuum pressure impregnated, Insulated, Partially transposed, Extruded, and Roll-formed apparently

en.wikipedia.org/wiki/Josephson_effect

He also sort of explained why it makes no sense that everyone is freaking out about LK-99. Even if the original team had been correct, they were claiming a saturation current that makes the conventional superconductors look high capacity.

@@TrabberShirthe exciting thing is that it proves that a room temperature superconductor is possible (if it’s not a hoax). By analyzing this, we could learn more about how superconductors work, potentially giving us the key to making a much more practical room temperature superconductor.

@@ahumanperson3649 There paper proposes a mechanism for high temperature superconductivity that, if valid, opens the door to engineering superconductors rather than searching blindly, which is essentially how the search for superconductors is still done. That theoretical work may be incredibly valuable event if LK-99 isn't a superconductor at all, because whether that mechanism actually implies LK-99 is a superconductor is not clear. But discovery of new high temperature superconductors has not meaningfully moved forward the work toward a useful theory of high temperature superconductivity in the past and there is not reason to thing LK-99 will be any different in that respect.

@@TrabberShir I have no idea what you are trying to say

LK-99 is complete bullshit as in: it's nothing new. High temperature superconductors have been around for thirty years and the reason why all the hype for this is absolutely misguided and ridiculous is the fact that there is no practical uses for it. It's a brittle ceramic from which you cannot make wires and it doesn't take heat nor high voltages well.

One of the more clever innovations that enabled this was the development of the "metal insulated" coil. Basically just solder the coil into a solid block and it still works as a coil when cooled and super-conducting. It's a simple solution to deal with the mechanical stress caused by high magnetic fields.

@@martylawson1638 copper has a resistance 10^5 ohm-m more (or higher) than a type 2 super conductor so i guess the ratio of current running around the loop in the direction you want, to the "resistance shunt" through the metal isn't that high :) the thought of using metal as an insulator.. - even pcb boards "only" offer a few G-ohm between traces ...

Saturation?

@@Taka.1011 I very well could be using a term wrong since I just learned about the limits of some superconductors a few days ago. I heard the term saturation used when the superconductor reaches a current or magnetic field limit and ceases to act as a superconductor. ie current saturation. The term is borrowed with good reason from inductor terminology. A core of an inductor can only direct? contain? a limited intensity magnetic field before the core becomes "saturated" and the inductor completely looses all properties of an inductor. (This is a failure mode for poorly designed switch mode power supplies. If you push your magnetics into saturation the impedance drops to the resistance of the wire itself and usually smokes the switch) I hope I'm not misleading you, but I'm like 85% sure all of that is at least close enough for KZfaq.

@@jonathanseagraves8140 yeah, now I understand what you meant, thank you!

The paranoia of the Russians is always their undoing 😮

RIP PAC-12

Well there are two reasons as video shows: 1) it's very complicated 2) it's not a large market However there are now Chinese magnets, but I don't know how good they really are - they are currently trying to brake into the European market however I haven't seen a quote yet

"Alot" is not a word.
