00:00 → 00:03
Hello everyone, this is Tech Daily's live video feed.
00:03 → 00:06
In July this year, a team of researchers in South Korea claimed that:
00:06 → 00:09
The discovery of the room temperature long pressure superconducting material LK99
00:09 → 00:11
It has sparked an online debate.
00:11 → 00:14
The debate in the academic world has not stopped.
00:14 → 00:17
And there's a group that believes that this is a supernatural illusion.
00:17 → 00:21
Recently published by Wuhan University of Technology.
00:21 → 00:24
Preprint of this paper published in collaboration with the University of Electronics and Technology
00:24 → 00:28
It seems to have given the LK99 a new twist.
00:28 → 00:31
Is there a superconductor in LK99?
00:31 → 00:34
Today we hired one of the authors of the paper.
00:34 → 00:39
Professor Yang, Faculty of Physics and Photovoltaics, Wuhan University of Technology
00:39 → 00:41
Professor Yang, how are you?
00:41 → 00:42
How are you?
00:42 → 00:46
Professor Yang, this year's superconducting heat in the room
00:46 → 00:49
It's from the beginning of the year to the end of the year.
00:49 → 00:52
Scientists claim to have made a breakthrough
00:52 → 00:54
It was repeatedly withdrawn by the Politburo.
00:54 → 00:56
So in this case,
00:56 → 00:58
This paper we published
00:58 → 01:02
Do you have any stress?
01:02 → 01:04
Stress is good.
01:04 → 01:07
It's more excitement.
01:07 → 01:09
Because of this article?
01:09 → 01:11
In fact, we've reported on one.
01:11 → 01:14
It's a phenomenon that we've just discovered.
01:14 → 01:18
This phenomenon is in our store of knowledge.
01:18 → 01:21
He has also consulted with a number of experts.
01:21 → 01:23
I've also done a lot of research.
01:23 → 01:26
It's also been repeatedly searched in the literature.
01:26 → 01:28
No such phenomenon has been found.
01:28 → 01:31
It's a kind of memory effect of this kind of glass.
01:31 → 01:32
So what?
01:32 → 01:35
I think it's worth reporting on.
01:35 → 01:37
Of course I know you will.
01:37 → 01:39
This is the room temperature superconductor.
01:39 → 01:40
The ups and downs of this year
01:40 → 01:42
Everyone is suspected of faking it.
01:42 → 01:45
Some are suspected of being kidnapped by the Politburo.
01:45 → 01:47
So we published this article.
01:47 → 01:50
It's not a question of whether or not he's going to be questioned.
01:50 → 01:51
It's been on for days.
01:51 → 01:52
That's good.
01:52 → 01:53
Most of them are still encouraging us.
01:53 → 01:57
I think this new phenomenon is interesting.
01:57 → 01:59
It's worth a visit.
01:59 → 02:02
Let's take a look.
02:02 → 02:04
So what is the main reason?
02:04 → 02:07
Mostly because of our research methods.
02:07 → 02:10
It's probably not quite the same as the others.
02:10 → 02:12
Because of superconductivity?
02:12 → 02:17
The direct experimental means was to study his direct current resistance and direct current magnetization.
02:17 → 02:21
This is called the zero resistance and the Meissner effect.
02:21 → 02:23
And what about this technology that we're using now?
02:23 → 02:27
The so-called low-tech microwaves are absorbing this technology.
02:27 → 02:29
He's not for the supernatural.
02:29 → 02:30
It's not enough.
02:30 → 02:32
It is not a prerequisite.
02:32 → 02:34
So what?
02:34 → 02:36
In other words, we have the material.
02:36 → 02:37
He's not a psychic.
02:37 → 02:38
But he absorbs microwaves.
02:38 → 02:40
There are also superconducting materials.
02:40 → 02:42
But he doesn't absorb microwaves.
02:42 → 02:46
So why are we still using this kind of technology?
02:46 → 02:51
And that's mainly because we're still in the very early stages of studying this material.
02:51 → 02:54
This is the art system we have.
02:54 → 02:57
This synthetic process is very immature.
02:57 → 02:58
So what?
02:58 → 03:04
Even if he had this superconductor in him, it's very low in the active ingredient.
03:04 → 03:08
So now you're just going to go straight to the conventional ways.
03:08 → 03:12
In fact, it's hard to measure these things with a zero-resistance magnetometer.
03:12 → 03:13
That's why.
03:13 → 03:19
A very important reason why this article from South Korea has been repeatedly questioned since it came out.
03:19 → 03:21
And this microwave technology that we're using.
03:21 → 03:22
What is his greatest benefit?
03:22 → 03:24
He is highly sensitive.
03:24 → 03:26
His accuracy is very high.
03:26 → 03:29
That's when his experimental data came out.
03:29 → 03:32
The data itself cannot be questioned.
03:32 → 03:35
Because his technology is very advanced.
03:35 → 03:38
So all you have to do is say your explanation.
03:38 → 03:41
He's the originator of this phenomenon.
03:41 → 03:43
Is it caused by superconductivity?
03:43 → 03:46
That's something we can discuss.
03:46 → 03:47
But what about this?
03:47 → 03:55
It's not about the data or the reality of the experiment itself.
03:55 → 04:00
So this is the material that we're actually developing now in materials science.
04:00 → 04:03
It's not enough, and it's not necessary.
04:03 → 04:04
But what?
04:04 → 04:06
This technology is still very useful.
04:06 → 04:11
Because we actually know what systems are.
04:11 → 04:14
He's going to be in the low field when the magnetic field is lower.
04:14 → 04:16
He absorbs microwaves.
04:16 → 04:17
Except for the superconductor.
04:17 → 04:23
For example, two-dimensional electrons in soft ferrous materials or semiconductors absorb microwaves.
04:23 → 04:23
But what?
04:23 → 04:29
We can use our experiment to rule out some of the possible choices.
04:29 → 04:35
Let's say I can turn the magnetic field to suppress the signal, or even make it disappear.
04:35 → 04:39
Then this phenomenon proves that he must not be ferromagnetic.
04:39 → 04:44
Because the definition of ferromagnetism is that your magnetic field amplifies this signal.
04:44 → 04:46
Through an exclusion like ours?
04:46 → 04:49
So the last one to reach the end is the one left.
04:49 → 04:52
This could be the end result.
04:52 → 04:55
So this is our exclusion method.
04:55 → 04:58
That's why we're writing this article now and putting it online.
04:58 → 04:59
Let's talk about it.
04:59 → 05:02
We all benefit from it.
05:02 → 05:03
Let's see.
05:03 → 05:03
Right.
05:03 → 05:06
Except that our knowledge is limited.
05:06 → 05:07
Is there any other?
05:07 → 05:13
It's a phenomenon that we don't know exists in the systems of some experimental materials.
05:13 → 05:15
If someone comes up with a new idea
05:15 → 05:19
We can go on to verify or falsify.
05:19 → 05:21
I don't think there's any pressure.
05:21 → 05:23
I thought it was science.
05:23 → 05:26
It's about allowing yourself to succeed or fail.
05:26 → 05:26
This is normal.
05:26 → 05:28
As long as we have this data.
05:28 → 05:30
The experimental data itself is real.
05:30 → 05:31
Is repeatable
05:31 → 05:32
It's also fun.
05:32 → 05:35
I think that's enough.
05:35 → 05:36
Thank you very much.
05:36 → 05:38
Can you give us some more details?
05:38 → 05:42
This is the LK99 that we tested.
05:42 → 05:45
It has this superconductivity.
05:45 → 05:48
Is there anything new to surprise us all?
05:48 → 05:58
Superconductivity is actually an umbrella term for a number of strange phenomena including electromagnetic radiation and heat.
05:58 → 06:03
So some of the ways that we see superconductivity as a confirmation of superconductivity.
06:03 → 06:07
Let's say this four-electrode amplifier measures the voltage.
06:07 → 06:07
Right.
06:07 → 06:09
This is called zero resistance.
06:09 → 06:15
Or you could use the VSM, which is the vibration sample, in the magnetic field to measure its anti-magnetism.
06:15 → 06:17
This is called the Meissner effect.
06:17 → 06:18
But other than that?
06:18 → 06:20
There are other ways of measuring it.
06:20 → 06:23
So let's say that this is a variation of the equation of a ferromagnetic
06:23 → 06:27
Or measure the Josephson effect of this superconducting inhibition.
06:27 → 06:30
Or with this scanning tunneling microscope.
06:30 → 06:34
Or the photon spectrum can be used to measure its superconductivity, and so on.
06:34 → 06:37
Of course, microwaves are a measurement.
06:37 → 06:39
In the actual measurement
06:39 → 06:41
All of the above ways
06:41 → 06:45
There's no way to go through one of them alone.
06:45 → 06:50
You can say with certainty that a material is a superconductor.
06:50 → 06:52
So if you measure zero resistance or you measure mesner.
06:52 → 06:56
In fact, even if this data alone is not enough.
06:56 → 06:59
We usually want to be sure about a system.
06:59 → 07:01
It's a super material system that is superconductive.
07:01 → 07:06
We need at least two of the above experiments.
07:06 → 07:12
You can't cross-check to tell you that this material is a superconducting system.
07:12 → 07:14
Otherwise, it's easy to become contaminated.
07:14 → 07:18
So what we have now is a technology that only uses microwaves.
07:18 → 07:24
All that can be said is that there may be some superconductivity in it.
07:24 → 07:24
Why?
07:24 → 07:28
Because we found a very peculiar memory effect.
07:28 → 07:29
What about the memory effect?
07:29 → 07:32
It's brought to you by glass beads.
07:32 → 07:34
So what does this glass mean?
07:34 → 07:42
It means that it's exerting this effect by adding magnetic fields and microwaves from different directions.
07:42 → 07:48
This material itself, it's going to remember this microwave effect on it.
07:48 → 07:48
And then what?
07:48 → 07:50
It's going to last for an hour.
07:50 → 07:53
A day as a unit
07:53 → 07:54
What if, as an analogy,
07:54 → 07:54
You can imagine.
07:54 → 07:56
It's like a microwave.
07:56 → 07:57
You're heating a bowl.
07:57 → 07:58
You dropped it.
07:58 → 08:02
Put it out there for a day.
08:02 → 08:03
It's cooling down.
08:03 → 08:05
A phenomenon like this.
08:05 → 08:07
What about a glass jar like this?
08:07 → 08:09
In our condensed matter physics,
08:09 → 08:11
There are two main types.
08:11 → 08:13
One of them is spinning glass.
08:13 → 08:16
One type is what we call superconducting spiral glass.
08:16 → 08:21
What we're doing now is actually changing the size of the magnetic field by changing the direction of the magnetic field.
08:21 → 08:24
And this frequency of this magnetic field, and so on.
08:24 → 08:27
Some experiments like this to test.
08:27 → 08:30
Confirmed it's not from the spinning glass.
08:30 → 08:36
So what's left is very likely this superconducting spiral glass.
08:36 → 08:41
Of course, that's just one of the most likely explanations that we have right now.
08:41 → 08:43
The most likely of all explanations.
08:43 → 08:45
Of course you said there were no other possibilities.
08:45 → 08:48
Of course, this material system is complex.
08:48 → 08:54
So this is to see if a system is caused by some physical mechanism.
08:54 → 08:57
It's also a matter of repeated experimentation.
08:57 → 09:00
That's what we're going to do after we post this article.
09:00 → 09:03
And then we're going to go down and we're going to do a very important point.
09:03 → 09:05
So what do we do now?
09:05 → 09:10
In fact, one of the important purposes is to use it as a screening tool, an early screening tool.
09:10 → 09:12
It's that we've made so many samples.
09:12 → 09:14
Which one has a signal, which one doesn't?
09:14 → 09:21
In this way, we can see which of these possibilities exist.
09:21 → 09:27
So, is the LK99's purity and its macroscopic size now feasible?
09:27 → 09:28
Not yet.
09:28 → 09:31
We now even think of it as superconductive.
09:31 → 09:33
It's also very low in this component.
09:33 → 09:38
It's about two or three hundred nanometers, give or take.
09:38 → 09:41
It's a few orders of magnitude smaller than our hair.
09:41 → 09:43
So very, very few.
09:43 → 09:47
So one of our main goals right now is to make it big.
09:47 → 09:48
Titanium
09:48 → 09:51
And that's one of the biggest challenges of this technology.
09:51 → 09:55
That's the biggest challenge in this synthetic craft.
09:55 → 09:58
And that's why we use this microwave to filter.
09:58 → 10:00
Because if you're this small,
10:00 → 10:04
In fact, it's hard to measure it any other way.
10:04 → 10:05
Because it's too small.
10:05 → 10:06
It's not like other sensitivities.
10:06 → 10:10
Only microwave sensitivity can meet this requirement.
10:10 → 10:11
What about the future?
10:11 → 10:13
We already have some plans.
10:13 → 10:16
Of course, we actually have some samples now.
10:16 → 10:20
The size of this sample is slightly larger than the one in this report.
10:20 → 10:21
Is there a future?
10:21 → 10:24
Of course, we have to improve the level of this craft.
10:24 → 10:26
Let's take it one step further.
10:26 → 10:28
Like some of the other methods
10:28 → 10:32
Some of them, including some of my friends, have given valuable suggestions.
10:32 → 10:34
It's about helping us improve the craft.
10:34 → 10:38
And now we're going to do it right away.
10:38 → 10:42
A lot of the equipment is in place so we can continue.
10:42 → 10:44
Good for you, Professor.
10:44 → 10:48
So there's been this controversy ever since LK99 came into existence.
10:48 → 10:51
So why do we choose to study it?
10:51 → 10:54
First of all, it's a historical clue.
10:54 → 10:57
The same chemicals are superconducting after the Nobel Prize.
10:57 → 11:00
For a long time, we've all been in the same boat.
11:00 → 11:02
It's all the elements of a desperate struggle.
11:02 → 11:06
It is possible to achieve higher superconducting temperatures.
11:06 → 11:07
So this experiment with lead.
11:07 → 11:12
It's actually an experiment that was done by a group in Eastern Europe at the time.
11:12 → 11:14
In fact, some of the results were already there.
11:14 → 11:15
But later for historical reasons.
11:15 → 11:17
The project is over.
11:17 → 11:20
So the Korean teacher of this LK99, this LK and these two.
11:20 → 11:24
It was after I returned to Korea from studying in Eastern Europe.
11:24 → 11:26
He's still working on it.
11:26 → 11:28
So what?
11:28 → 11:32
This same chemical is the most stellar material in a superconductor.
11:32 → 11:35
It's also the most likely to achieve higher temperatures.
11:35 → 11:37
This is a public acknowledgement.
11:37 → 11:41
So this is using the same chemical to keep the temperature up.
11:41 → 11:42
The temperature of the superconductor itself.
11:42 → 11:48
This is a long-standing research topic in the field of superconductivity.
11:48 → 11:49
Even without LK99
11:49 → 11:52
And you're going to think about other ways to improve the same chemicals.
11:52 → 11:55
So where are the LK99's bright spots?
11:55 → 11:56
What's their main highlight?
11:56 → 12:02
It's this copper replacing this lead atom.
12:02 → 12:03
Because of the lead?
12:03 → 12:05
It's very heavy, very heavy.
12:05 → 12:06
The radius of an atom is very large.
12:06 → 12:07
What about the copper?
12:07 → 12:08
Is relatively small
12:08 → 12:10
So what happens when you replace lead with copper?
12:10 → 12:13
This material, it's going to get tighter.
12:13 → 12:16
This internal pressure is going to be greater.
12:16 → 12:17
So, what about theoretically?
12:17 → 12:18
What if the pressure is greater?
12:18 → 12:22
It's much easier to achieve this higher superconducting temperature.
12:22 → 12:25
It's theoretically predicted.
12:25 → 12:26
What about me?
12:26 → 12:29
In fact, some other related research was done that year.
12:29 → 12:34
So what I'm doing is I'm trying to figure out how to increase the distance between these molecules.
12:34 → 12:35
The way we want, of course.
12:35 → 12:38
It's through, say, a free base.
12:38 → 12:41
It's a way of forming a free base layer and so on.
12:41 → 12:43
We've also made some strong connections.
12:43 → 12:47
So then I saw this article about LK99.
12:47 → 12:50
It's one of the theories, one of the assumptions.
12:50 → 12:53
I'm attracted to it.
12:53 → 12:55
Because this is the model of it.
12:55 → 12:57
It's actually a very new model.
12:57 → 13:00
At least in my opinion, it's very interesting and new.
13:00 → 13:03
So it's worth a try.
13:03 → 13:06
So that's July and August of this year.
13:06 → 13:08
What happened after their article went online?
13:08 → 13:11
In many parts of the country,
13:11 → 13:15
And the other thing about platinum is that it's a superconducting field.
13:15 → 13:18
And I started to go into this field to do this research.
13:18 → 13:19
Why?
13:19 → 13:21
First of all, of course, it's simple.
13:21 → 13:24
Because it's actually very cheap.
13:24 → 13:26
Lead, zinc, copper and oxygen
13:26 → 13:28
These are all regular elements.
13:28 → 13:30
The raw materials are cheap.
13:30 → 13:31
Secondly, what about the synthetic arts?
13:31 → 13:33
It's actually pretty simple.
13:33 → 13:35
It's better to burn an ordinary rabbit.
13:35 → 13:38
There's no extra complicated craftsmanship.
13:38 → 13:41
So for a typical materials lab,
13:41 → 13:43
We can all do this.
13:43 → 13:45
So it's very low cost.
13:45 → 13:46
So from the beginning.
13:46 → 13:51
A lot of people come in with an attitude of trying things out.
13:51 → 13:53
So what happens when the trial is over?
13:53 → 13:55
We burned the first samples and found them.
13:55 → 13:57
I'm going to take a look at this.
13:57 → 14:02
And what we find is all sorts of phenomena.
14:02 → 14:03
Some say it's made of iron.
14:03 → 14:05
Some say it's made of steel.
14:05 → 14:06
Others say it's self-selected glass.
14:06 → 14:07
Everything is there.
14:07 → 14:10
And there are all sorts of conclusions to be drawn.
14:10 → 14:11
This is very interesting.
14:11 → 14:12
Why?
14:12 → 14:14
It's because a piece of material makes sense.
14:14 → 14:17
It should be fairly consistent with what you burn out.
14:17 → 14:17
Right.
14:17 → 14:19
It's the same recipe as yours.
14:19 → 14:21
But the reality is that we're all very different.
14:21 → 14:24
No one knows who is right.
14:24 → 14:26
So what about our materials?
14:26 → 14:29
In fact, they're very sensitive to diversity.
14:29 → 14:33
It's just that there are things that can't be explained.
14:33 → 14:36
These strange phenomena are not uncommon.
14:36 → 14:40
The original curiosity was raised.
14:40 → 14:42
It's for scientific research.
14:42 → 14:44
There are some of the most primitive impulses
14:44 → 14:48
It's full of curiosity about phenomena that nature can't explain.
14:48 → 14:50
I just want to figure it out.
14:50 → 14:50
So what?
14:50 → 14:54
It's part of what we call the Replicator Alliance.
14:54 → 15:00
It's just a matter of sticking with it and trying to make it bigger and clearer.
15:00 → 15:01
So what now?
15:01 → 15:04
This is basically the beginning of this phenomenon.
15:04 → 15:07
From our current work.
15:07 → 15:11
I think there's a pretty clear explanation for that.
15:11 → 15:14
That's where the glass is.
15:14 → 15:18
Glass is a variety.
15:18 → 15:22
It's a state that doesn't have a length of this order.
15:22 → 15:23
So what?
15:23 → 15:24
Under different magnetic fields
15:24 → 15:28
It has some strange properties at different temperatures.
15:28 → 15:30
That makes perfect sense.
15:30 → 15:31
So what?
15:31 → 15:34
I think what you're asking is why did you choose it?
15:34 → 15:38
I think maybe the biggest part of this curiosity is
15:38 → 15:43
And that's what I'm talking about in terms of materials science.
15:43 → 15:47
Our main concern is not that you burned a pot of ingredients.
15:47 → 15:49
There's no sign of anything.
15:49 → 15:50
Just the background noise.
15:50 → 15:51
So this is the whiteboard.
15:51 → 15:51
No, not at all.
15:51 → 15:53
It's for the worst.
15:53 → 15:55
If I can detect a signal, it'll come.
15:55 → 15:56
We were happy.
15:56 → 15:58
After all, we can fix it.
15:58 → 15:59
And this phenomenon?
15:59 → 16:02
It's the past we haven't seen.
16:02 → 16:03
This is a new phenomenon.
16:03 → 16:04
It doesn't matter.
16:04 → 16:08
It's one of those things where you know what you're doing.
16:08 → 16:09
So that's the main reason I think.
16:09 → 16:12
And then there's Professor Wu.
16:12 → 16:14
Why is this room temperature superconducting this region?
16:14 → 16:16
The research is always a blast.
16:16 → 16:18
Where is it?
16:18 → 16:20
What's the problem?
16:20 → 16:23
I think we can divide it into subjective and objective.
16:23 → 16:24
Subjectively
16:24 → 16:26
Of course it's because of this room temperature superconductor.
16:26 → 16:29
It's a science after all.
16:29 → 16:31
A holy grail of condensed maternal physics
16:31 → 16:33
It's very influential.
16:33 → 16:35
There's a lot to be gained.
16:35 → 16:37
There must be a lot of people who want to.
16:37 → 16:38
I'm not going to take the risk.
16:38 → 16:38
Right.
16:38 → 16:41
Doing something that's not so reliable.
16:41 → 16:42
This is a subjective factor.
16:42 → 16:44
So I'd like to think about the first half of this year.
16:44 → 16:46
Bombing the system
16:46 → 16:47
The second system.
16:47 → 16:50
Now many people think it is.
16:50 → 16:52
It's not very reliable.
16:52 → 16:54
This one might have some issues.
16:54 → 16:56
This is a subjective factor.
16:56 → 16:58
What about the objective factor?
16:58 → 16:59
That's right.
16:59 → 17:01
Because of our nature.
17:01 → 17:03
Substance with more elements
17:03 → 17:06
The more structured it is.
17:06 → 17:08
Diversity is more complicated
17:08 → 17:10
Our regular elements are superconducting.
17:10 → 17:13
Or these superconducting systems of binary compounds.
17:13 → 17:15
Basically, we're finished.
17:15 → 17:17
Most of them have been found.
17:17 → 17:20
So what about this superconductivity study?
17:20 → 17:22
The main target is the triad.
17:22 → 17:23
Quaternary
17:23 → 17:25
And then we're going to have even more elements of this combination.
17:25 → 17:27
Its ceramic or its alloy
17:27 → 17:31
So for some of these multi-component materials
17:31 → 17:33
Our theoretical predictions are very ineffective.
17:33 → 17:35
Because it's too complicated.
17:35 → 17:36
Diversity is too complicated
17:36 → 17:39
So what happens when the structure gets complicated?
17:39 → 17:44
It's the same energy in this structure.
17:44 → 17:45
These structures
17:45 → 17:48
This would be a significant increase in the share of
17:48 → 17:50
Previous studies have been superconductive.
17:50 → 17:52
It's also cooler.
17:52 → 17:54
Thousands or tens of thousands.
17:54 → 17:56
So what happens at such low temperatures?
17:56 → 17:58
Its different energies.
17:58 → 17:59
Not even close.
17:59 → 18:01
It's not particularly sensitive.
18:01 → 18:03
Because of your humility.
18:03 → 18:06
The low-energy structures are the ones that dominate.
18:06 → 18:09
But what about indoor heating?
18:09 → 18:11
Because it's going to increase this temperature.
18:11 → 18:14
So in this structure of yours,
18:14 → 18:16
It's not very stable.
18:16 → 18:18
Those who are depressed.
18:18 → 18:21
And it's not just a question of whether or not it's going to work.
18:21 → 18:24
And these experiments that we're doing.
18:24 → 18:26
It's not like it used to be.
18:26 → 18:29
Our current experimental apparatus is too sensitive.
18:29 → 18:31
It's very, very acute.
18:31 → 18:33
Even if you only have a few dozen or a few hundred nanometers.
18:33 → 18:36
It can also detect a signal.
18:36 → 18:37
How about this?
18:37 → 18:39
The benefit, of course, is that we can.
18:39 → 18:42
In a small amount of this active ingredient,
18:42 → 18:46
It's possible to find it.
18:46 → 18:50
This could be the superconducting factor.
18:50 → 18:50
But what?
18:50 → 18:53
There are some downsides.
18:53 → 18:56
It's not supposed to be superconducting.
18:56 → 18:58
And that's what's bothering you.
18:58 → 19:01
It's supposed to be rigid.
19:01 → 19:03
Not stable
19:03 → 19:04
It also interferes with your structure.
19:04 → 19:05
So what?
19:05 → 19:08
And that's why we're in this mess right now.
19:08 → 19:09
Superconducting research.
19:09 → 19:12
Its owl is actually more.
19:12 → 19:13
And we have this one.
19:13 → 19:15
From our experiment.
19:15 → 19:16
I just said that.
19:16 → 19:19
Because the glass itself is a solid piece of glass.
19:19 → 19:22
It's supposed to be sensitive to this temperature.
19:22 → 19:24
So you're also sensitive to its magnetic field.
19:24 → 19:26
The direction of the magnetic field is what we measured.
19:26 → 19:29
It's also influenced by it.
19:29 → 19:30
So what?
19:30 → 19:33
What we've done is
19:33 → 19:35
This is a different kind of stability.
19:35 → 19:38
In this measurement process,
19:38 → 19:40
Some of the effects could be:
19:40 → 19:42
It makes you think it's superconductive.
19:42 → 19:43
Maybe it's not a superconductor.
19:43 → 19:44
So what if this is it?
19:44 → 19:47
It's possible that an owl was formed.
19:47 → 19:49
I think that's the main reason.
19:49 → 19:52
I'll talk to you later.
19:52 → 19:56
What are your expectations for next year?
19:56 → 19:57
That's right.
19:57 → 19:59
What about us now?
19:59 → 20:00
What about this experiment?
20:00 → 20:03
Moving Forward
20:03 → 20:04
So what's the goal now?
20:04 → 20:06
There are mainly two.
20:06 → 20:07
The first one?
20:07 → 20:12
And that's what we're trying to do now.
20:12 → 20:16
It's possible to make a suspended sample under a magnetic field.
20:16 → 20:16
This one?
20:16 → 20:19
Because we already had some samples.
20:19 → 20:20
What about now?
20:20 → 20:21
What happens after these samples are made?
20:21 → 20:23
Let's take a closer look at its composition.
20:23 → 20:26
Or its components come from
20:26 → 20:28
Superconducting or Ferromagnetic
20:28 → 20:30
That's one of our current goals.
20:30 → 20:31
So what's next?
20:31 → 20:34
Of course, to make it bigger.
20:34 → 20:38
It's going to be as small as possible.
20:38 → 20:41
Even on a larger scale.
20:41 → 20:43
So what if this is it?
20:43 → 20:46
So it's possible to measure this zero-resistance effect directly.
20:46 → 20:47
Or the Meissner effect.
20:47 → 20:52
Here are some of the things we're going to do right away.
20:52 → 20:53
So what else is there?
20:53 → 20:57
We ourselves have a greater advantage.
20:57 → 21:00
It's in this direction, this application of this microwave.
21:00 → 21:02
This material LK is this material.
21:02 → 21:06
Its microwave response is very strong.
21:06 → 21:07
Its signal is very strong.
21:07 → 21:13
So he's going to have a lot of use cases for microwaves.
21:13 → 21:15
For example, we've covered this in an earlier post.
21:15 → 21:18
Can he use it in quantum computing?
21:18 → 21:19
Wait a second.
21:19 → 21:21
Some directions like that.
21:21 → 21:24
You can even use it to make absorbent materials.
21:24 → 21:29
Or some memory material to do this microwave.
21:29 → 21:30
Memories and so on.
21:30 → 21:32
Some of the applications are:
21:32 → 21:34
What about next year?
21:34 → 21:38
We'll also put in some time and effort.
21:38 → 21:41
Some of the research to be done in this area
21:41 → 21:42
Thank you very much.
21:42 → 21:44
Thank you for joining us.
21:44 → 21:47
Thank you. Thank you.
