Welp I've learned a hard lesson in the dangers of joining hype trains. Replication and peer review came to the conclusion that LK-99's claims of being a superconductor are false. In fact, it seems to be a worse conductor than just copper at room temperature. Summary Article

So it goes. Not the first false superconductor claim, won't be the last.

Scientists reveal the first unconventional superconductor that can be found in mineral form in nature

Scientists from Ames National Laboratory have identified the first unconventional superconductor with a chemical composition also found in nature. Miassite is one of only four minerals found in nature that act as a superconductor when grown in the lab. The team's investigation of miassite revealed that it is an unconventional superconductor with properties similar to high-temperature superconductors. Their findings, published in Communications Materials, further scientists' understanding of this type of superconductivity, which could lead to more sustainable and economical superconductor-based technology in the future. Superconductivity is when a material can conduct electricity without energy loss. Superconductors have applications including medical MRI machines, power cables, and quantum computers. Conventional superconductors are well understood but have low critical temperatures. The critical temperature is the highest temperature at which a material acts as a superconductor.

Finally listening to all of The Superconducting Supercolliders work..

Designations has me in a chokehold.

(This music is so good, though???)

[crynwr-drwg]

This is huge news. Probably some of the biggest news we might get in a lifetime

holy shit, STP superconductor. Huge if true.

(That being said, it’s arxiv and I don’t quite have the background to fully process the validity of this; if you do, please leave thoughts.)

LK-99 SUPERCONDUCTOR!!!!!!!!!!!

SO FUCKING HYPED. The LBNL (Lawrence Berkeley National Lab) simulations show LK-99 (not 100% proof, but damn good evidence) is actually for real a superconductor. This, along with their showing that it only acts as a superconductor with the copper in an energetically unfavorable (high energy) position explains basically all the failures to reproduce and why the people who did have success (like Iris and the chinese labs that showed some weak levitation) did not have results that look as impressive as we'd usually see from more conventional superconductors. Anyway, thank you so much to Iris because she's the most based researcher i know of working on this. Also, i know that it's not a totally settled issue, but the evidence in favor of it is so much stronger than the evidence to the contrary IMO.

Okay, so, i got distracted for like 3 hours after writing this, but still very hyped. Looking forward to new methods of production, so once i move into college i'll probably try to work on a new synthesis of it, but real quick, what do y'all think of me trying to (with no experience, kinda just educated shots in the dark) make another material that uses the same doping technique? That is to say (more descriptively) attempting to make a hexagonal, potentially just apatite again, mineral that has one of its metal ions replaced with something else that forces the hexagons to expand or contract (hopefully making a superconductor (but like, very low odds))

If verified, huge, likely not verifiable it seems.

I read an article by Ceri Perkins for Sciencefocus.com about CERN!! 'CERN: Everything you need to know' published June 2022.

The things which stood out to me were:

CERN was established in 1954 to prevent the brain drain of European scientists leaving for America, which I think has worked well since over 10,000 scientists work there and is quite famous and is in pop culture - e.g Steins Gate

In 1983 W and Z bosons were discovered at CERN

Tim Berner Lee helped create the world wide web at CERN in 1983, something which has greatly changed all of our lives!!

Anti hydrogen was created!?!? Hydrogens anyiparticle?? Tho I'm not entirely sure what this is ToT I guess it's just an antiproton and an antineutron with an antielectron?!?! Imma have to look it up ;-;

QUARK GLUON PLASMA!?!?! WHATS THIS!?!? A NEW STATE OF MATTER NAMED AFTER MY BOYS QUARKS!?!?

Also the particle collider itself is created by superconducting magnets!! And they're cooled to -271.3°c so about 10K ish....you know what super conductors are!?? They're conductors which are cooled below a critical/ transition temperature where the conductor gains a resistance of zero!! Its verrry efficient!! Hence why it's used here!! However its verrry expensive so the real question is whether its cheaper to use super conductors or to have resistance? But with superconductors the current could effectively move forever and the energy transfers would be 100% efficient but the cost of cooling it?? What do you think?

Tests show high-temperature superconducting magnets are ready for fusion

In the predawn hours of Sept. 5, 2021, engineers achieved a major milestone in the labs of MIT's Plasma Science and Fusion Center (PSFC), when a new type of magnet, made from high-temperature superconducting material, achieved a world-record magnetic field strength of 20 tesla for a large-scale magnet. That's the intensity needed to build a fusion power plant that is expected to produce a net output of power and potentially usher in an era of virtually limitless power production. The test was immediately declared a success, having met all the criteria established for the design of the new fusion device, dubbed SPARC, for which the magnets are the key enabling technology. Champagne corks popped as the weary team of experimenters, who had labored long and hard to make the achievement possible, celebrated their accomplishment.

Type-II Superconductor

[vexillologyisenjoyable]

IDIOT

the person who made this comic is a FOOL and deserves to be MOCKED

a semiconductor is a material that is less conductive than conductors like metal, but more conductive than insulators like rubber. A room temperature semiconductor is a piece of germanium or a different semiconductor that’s around 70 degrees Fahrenheit. Which is nothing. It’s an object that’s a certain temperature. It doesn’t change anything.

amplifying or switching currents is what transistors do.

a room temperature SUPERconductor wouldn’t amplify or switch current, it would have zero resistance at room temperature.

Basically, the comic calls transistors semiconductors, and says that the character invented room temperate transistors, which is nothing. A room temperature transistor is like a room temperature piece of cheese. It’s fine that it’s that temperature, but it doesn’t change anything.

From Lasers to Superconductors: The Optoelectronics Chip Revolution Begins

By Max Planck Institute for the Structure and Dynamics of Matter November 20, 2023 Scientists have actually effectively shown superconductivity on a chip, exposing non-linear electrical actions in K3C60 thin movies and observing crucial present habits. This cutting-edge research study, which utilizes on-chip non-linear THz spectroscopy, opens brand-new opportunities in optoelectronic…
