台灣以前有個破紀錄的發明 "石頭+水" 就可當汽油用
韓國研發要跟台灣比 天差地遠

我才剛說, 今天下午就看到有人在開箱台大的實驗室了...

直播中 台大實驗室LK-99開箱，實做+實測室溫超導體！ 30小時以上直播馬拉松

不能說沒有, 也不是某人說的喜歡宣傳

對岸主要是這幾年本來就有研究高溫超導體的團隊(不只一個實驗室)
而研究出的應用也確實有市場(國產MRI)

台灣的超導體實驗室... 基本上沒有應用與商業環境

交大也有研究超導的團隊。
還沒消息最有能是原料下單了還沒寄到。

就只有中國有好幾個研究高溫超導體的實驗室嗎？

那為什麼就只有中國這麼多實驗室在放消息？

要幫忙講點什麼也不要這麼沒邏輯

更何況也沒有說宣傳是不好的，真的是槓精

比中國水變油還厲害嗎？

東南那個所謂測到零電阻, 大概率是測到銅金屬; 至於是試料燒結過程析出銅, 還是測試用電極短路造成? 啊耶災......

只好耐心等各國 team 接下來做電阻測試了.
Andrew McCalip 個人實驗也做到 levitation 了, 相信會越來越多人開始做電阻測試才是?

Reddit 有人放 Kim Hyeon Tak interview 的內容, 有談到為何原始文件沒放電阻資料
Q. You didn't offer resistivity data so some people wonder if supreconductivity is true.
A. (omitted)We already put resistivity data in earlier paper. So we thought we don't have to insert such data into second paper(which is in arXive)

1. Why wasn't this published as a formal paper?

- There were unavoidable circumstances. We reported it in a journal at the same time.

2. Two papers exist in the archive. Why?

- The authors of the first paper disagreed. The second paper has many authors, and the authors agree, so the first paper is wrong.

3. I heard that the Korean Society for the Verification of Room Temperature Superconductivity requested samples for verification.

- Our team agreed to 'help' the Korean researchers to do their research, but verification is a different matter.

4. Why isn't the resistance zero?

- If the resistance drops discontinuously low in a metal, it is a superconductor, because whether the resistance is zero or not is a matter of noise. I've already written about the presence of noise in experiments in the paper. The question of whether the resistance of a superconducting state is zero or not was debated over 100 years ago. This is a debate that follows every time a superconducting phenomenon is discovered. I had already written in my first paper that there was a discontinuous "jump" and that when I actually measured it, the resistance was zero. So we didn't put it in the second paper. We didn't write it down because we knew it.

5. Why doesn't LK-99 float completely?

- Our sample produces a one-dimensional superconductor, so next to a straight line of superconductor it is a non-metal. When measured, they appear together. We did not make a very uniform sample. So it floats at an angle.

6. No Qeustion

So, even if we develop the technology in the future, it's not going to be as good as a two- or three-dimensional superconductor. But I think we can cut through the first dimension. This is where a lot of technology development is needed. We are just getting started.

7. How did you get involved in this research?

My thesis came out in 2021, and a research institute contacted me that they had made a superconductor. They said they didn't have enough theory, so they reached out to me.

8. How do you recognize a superconductor?

The first way to tell if something is superconducting or not is that there is a "jump".

There is a discontinuous jump between a state with an energy gap and a state without.

In other words, in a metal that is superconducting or not, a jump towards lower resistance is superconducting.

9. There are semiconductors called MIT materials that are not superconductors.

It is an MIT material that jumps to the side where the resistance increases.
