Scientific Investigation Bureau: Replicating Room Temperature Superconductivity Experiment
Subtitle language:
00:00 → 00:02
Hello everyone, welcome to the Office of Scientific Research of Professor Sun.
00:02 → 00:05
The long-awaited room temperature superconductor re-experience
00:05 → 00:07
We finally have preliminary results.
00:07 → 00:08
Let's see what we can learn from this.
00:09 → 00:12
In fact, for a researcher who has been studying superconductivity for over a decade,
00:12 → 00:15
I'm skeptical about this room temperature superconductor.
00:15 → 00:19
If you've seen my previous two videos, you should know that.
00:19 → 00:21
But room temperature superconductivity is also a very important thing.
00:21 → 00:24
And by the way, we don't know what's uncertain.
00:24 → 00:27
We have to practice the scientific approach that we have to accept.
00:27 → 00:32
So we did our own experiment to recreate a room-temperature superconductor.
00:32 → 00:34
Okay, enough of this bullshit.
00:34 → 00:36
Below is a timeline of what we're doing.
00:36 → 00:40
We recreated the entire process of this room temperature superconductivity and our preliminary results.
00:40 → 00:43
We saw the article on July 25.
00:43 → 00:44
And then decided to try it.
00:44 → 00:46
Then they started buying raw materials.
00:46 → 00:48
And then on the night of July 26th, our raw materials arrived.
00:48 → 00:50
And then we defined the experimental protocol.
00:50 → 00:54
And then on July 27th, we started to synthesize the first suborbital propellant.
00:55 → 00:57
The first step is to synthesize two different types of sub-drives.
00:57 → 00:59
To prevent the raw materials from oxidizing in the air
00:59 → 01:04
We put the raw materials in the pressurized water tank and weighed them.
01:05 → 01:09
So what you're seeing is that we're going to have a process of levelling the scales.
01:15 → 01:16
After the raw materials are allocated
01:16 → 01:21
We'll need to grind the raw materials in the water tank.
01:21 → 01:22
Let it mix properly and evenly.
01:23 → 01:26
And then we put the raw materials in the lab.
01:26 → 01:28
Then vacuum it up.
01:28 → 01:30
This is also mentioned in the paper.
01:30 → 01:32
But there are contradictions in the article.
01:32 → 01:36
It's written in air where it's written in words.
01:36 → 01:37
Air-fired arrows
01:37 → 01:40
But the map shows a high vacuum.
01:40 → 01:42
So we did both of these experiments.
01:42 → 01:47
We synthesized a raw material from air.
01:47 → 01:49
Another raw material is vacuum.
01:49 → 01:51
Synthesized in a sealed laboratory
01:51 → 01:53
So this is the furnace in our lab.
01:53 → 01:55
In fact, we are all single-chambered.
01:55 → 02:00
We have prepared the raw materials for the study.
02:00 → 02:04
We put it in our hot furnace for the arrow.
02:05 → 02:06
We have two.
02:06 → 02:09
One is a vacuum-sealed material in a lab.
02:09 → 02:14
Another is to put the raw materials directly into the air.
02:15 → 02:17
So we set the temperature to the desired temperature.
02:17 → 02:18
Then fire the arrow.
02:19 → 02:21
It took us two days to do this.
02:21 → 02:23
Because it's a copper trihydrate compound.
02:23 → 02:26
The paper suggests that it should be burned for 48 hours.
02:28 → 02:31
So, two days later, we were able to synthesize these two precursors.
02:31 → 02:33
This is what we make of the raw materials.
02:33 → 02:37
To prevent the raw materials from being oxidized or moistened in the air
02:37 → 02:39
We all open the raw materials in stone boxes.
02:39 → 02:40
Then grind it
02:40 → 02:43
Then X-ray diffraction analysis is performed.
02:43 → 02:45
And that's a proof that we've got it right.
02:45 → 02:47
Two precursors of the in-gas structure
02:48 → 02:50
Well, after getting two precursors
02:50 → 02:53
We're going to be able to synthesize the final target material.
02:53 → 02:54
But this time in their article
02:54 → 02:56
It's actually a question of
02:56 → 02:59
And they're not going to be able to do that because they're using two raw materials that reflect the
02:59 → 03:01
In the final compound
03:01 → 03:02
Their copper to nickel ratio is 1 to 6.
03:02 → 03:05
But the precursor is copper trifluoride.
03:05 → 03:09
So you're actually having a hard time getting this straight.
03:09 → 03:13
So we tried two different equations.
03:13 → 03:16
And we know that our precursor combustion is also different.
03:16 → 03:19
Our precursor, one of them, burned up in a vacuum.
03:19 → 03:21
One is burnt in air.
03:21 → 03:24
And it's written in terms of the temperature of the synthesis, which is 925 degrees.
03:24 → 03:26
It's less than 20 hours.
03:26 → 03:27
This is a long time span.
03:27 → 03:31
So we took two conditions, 10 hours and 20 hours.
03:31 → 03:33
And then you have three different variables that are stacked on top of each other.
03:33 → 03:35
We did eight experiments.
03:35 → 03:38
And in this picture, you see three.
03:38 → 03:40
10 hours to burn a successful sample
03:40 → 03:42
So let's test the first experiment.
03:42 → 03:45
And this is the most familiar of all experiments with superconducting magnetic fields.
03:45 → 03:48
And then we put the synthetic sample on top of the cast iron red magnet.
03:48 → 03:52
We see the sample lying on the magnet.
03:52 → 03:54
There is no floating phenomenon.
03:56 → 03:59
So we then took a linear measurement of this sample.
03:59 → 04:01
We are the magnetic field with the gypsum.
04:01 → 04:04
ZFC FC measured from 200K to 400K
04:04 → 04:07
We haven't seen any signs of superconductivity.
04:07 → 04:09
We see ZFC FC is basically neutral
04:09 → 04:12
This sample does show some negative linearity signals.
04:12 → 04:14
It's a little bit of antimagnetism.
04:14 → 04:16
Weakly antimagnetic
04:16 → 04:17
But because the signal is so weak,
04:17 → 04:19
So we can't rule out that completely.
04:19 → 04:22
This anti-magnetism may be caused by impurities only
04:22 → 04:25
Then we measure the sample at 200K of magnetic feedback.
04:25 → 04:29
We know that a superconducting magnetic field exhibits a special magnetic feedback
04:29 → 04:31
And then we see what we have now.
04:31 → 04:34
It's just that there's some ferromagnetic this destructive
04:34 → 04:37
The sample may have a weak magnetic field.
04:37 → 04:39
But this ferromagnetism could also be from impurities.
04:40 → 04:44
So these are some of the preliminary results of our experiments so far.
04:45 → 04:49
We haven't seen any signals that could be superconducting.
04:50 → 04:52
Of course, we have seven different samples.
04:52 → 04:55
We'll take some of these measurements in turn.
04:55 → 04:59
And we're going to do this impedance measurement as soon as we can.
04:59 → 05:01
And then we'll see if the sample is really zero-resistance.
05:02 → 05:03
I'm not sure what to say.
05:03 → 05:07
Now, it's just that our preliminary experiments didn't observe any superconductivity.
05:07 → 05:11
But I can't completely rule out the possibility that this material is unstable and superconductive.
05:11 → 05:12
We need further purification.
05:12 → 05:16
Further measurements are needed to verify the material.
05:16 → 05:19
Because it does contain copper.
05:19 → 05:22
There's a lot of room for improvement.
05:23 → 05:25
So we have to verify the final result.
