Chapter 169
Xiaohao, how sure are you? !
Hear Xu Hao’s words.
Mr. Chen, who was walking out, stopped and then turned around slightly.
That face is full of wrinkles, but usually very determined.
There is only numbness at the moment.
He looked at Xu Hao with dull eyes.
Other scientific researchers looked at Xu Hao with doubts.
There were serious flaws in the data, and the experiment had failed.
Why did Xu Hao still say that they still had a chance?
It took a while.
Mr. Chen suddenly smiled bitterly.
“Xiao Hao, thank you for your comfort.”
“I just… have to admit that we have failed in this experiment!” ”
There are serious deviations in the data and serious mistakes in the material ratio, which caused the nanowire aerogel to connect to the initial stage. It didn’t hold up to the high temperature, alas…”
“We haven’t even tested it, but the Argonne National Laboratory in Eagle Country has stabilized it at 1000°C.”
Mr. Chen shook his head helplessly, with a look of dejection on his face.
He has been engaged in new ultra-high temperature materials for decades, participated in countless experiments, and experienced countless failures.
but!
The failure of today’s experiment was a huge blow to him.
The fruits of several years of labor were in vain.
Coupled with the ‘bad news’ coming from the other side of the ocean, it made his heavy heart even worse.
Mr. Chen raised his head, walked up to Xu Hao, patted his shoulder, and said with a forced smile.
“Xiao Hao, you are excellent.”
“Don’t worry, I will have someone vacate the laboratory in the next two days and lend it to you for experiments!”
Although he didn’t get along with Xu Hao for long.
But these days.
He saw Xu Hao’s efforts.
He could also see that Xu Hao was indeed a novice in materials science.
You can know this by watching him operate those instruments.
It’s just that…
he has been studying these aspects of knowledge these days, arriving early and coming home late, almost treating the laboratory as a dormitory.
Mr. Chen admires such students very much.
And Xu Hao’s performance today made his eyes shine even more.
Unfortunately, now that the experiment failed, he is no longer in the mood.
otherwise.
He tried his best to keep Xu Hao in the School of Materials Science and Technology of Huaqing University.
And at this moment.
Only the researchers in the laboratory understood.
It turns out that Xu Hao suddenly joined their project, not just to get experience gold plating.
Just made a deal with Mr. Chen to borrow the laboratory?
Think of this.
The expressions on everyone’s faces were very inexplicable.
Especially the scientific researcher who was doing the data compilation, his face was red at the moment and he was full of shame.
I want to step forward and apologize to Xu Hao.
But that’s when.
He saw Xu Hao pulling the blackboard from the side again and erasing the writing on it cleanly.
Then.
In full view of the public, write directly.
“Old Chen, we all know.”
“Compared with traditional thermal insulation materials, ceramic aerogels present excellent properties due to their low thermal conductivity and good chemical stability.” ”
But at the same time!”
“Made of oxides The brittleness of ceramics composed of nanoparticles and the structural collapse at high temperatures will limit the wide application of conventional ceramic aerogels.” ”
So, in recent years, both domestic and foreign countries have turned their attention to new recyclable graphene aerogels, such as natural drying Graphene aerogel, aminosilane cross-linked graphene aerogel, and three-dimensional graphene scaffold.”
“It’s just…”
At this point, Xu Hao paused slightly.
And at this moment.
Everyone in the laboratory focused their attention on Xu Hao.
Mr. Chen stood quietly in front of the blackboard, listening to Xu Hao’s explanation.
He didn’t know what Xu Hao was going to do, nor what he was going to do by suddenly talking about these theoretical knowledge.
But looking at the seriousness on Xu Hao’s face.
Mr. Chen was willing to take some time to listen carefully to what the young man was going to say next.
Without making everyone wait for too long, Xu Hao continued.
“However, since graphene-based materials are prone to decomposition above 600°C, they are difficult to use under high temperature and oxygen-containing conditions.”
Mr. Chen nodded slightly when he heard this.
“Yes, what you mentioned has been explored by research institutions at home and abroad.” ”
So, many institutions and laboratories have stopped research in this area and settled for other materials. ”
When Xu Hao heard what Mr. Chen said, a confident smile appeared on his handsome face.
Then he shook his head slightly and said bluntly.
“No!”
“They are all wrong. There is nothing wrong with the characteristics of this material. What is wrong is that they did not use the right method.”
As soon as he finished speaking, Xu Hao wrote on the blackboard.
“Using directional freezing method and heat treatment to prepare SiC@SiO2 nanowire aerogels with nanowire assembly anisotropy and hierarchical structure.” “The
specific material ratio is silicon-silica nanocomposite wrapped with porous carbon spheres, Nano-SiO2-NR/SiO-acrylic acid-polyurethane composite material, MXene@gelatin (M@G) composite aerogel…”
There are so many materials that the small blackboard cannot fit them all.
And as Xu Hao kept talking and writing.
Chen Lao’s dead eyes once again shone with a ray of light.
He hurriedly ordered the scientific researchers beside him who had been stunned for a long time.
“Why are you standing there?!”
“Quick! Bring a few more blackboards to Xiao Hao!”
Hearing Mr. Chen’s reminder, the researchers who looked at Xu Hao in a daze immediately reacted.
Especially the researcher who compiled the data.
Say nothing.
He immediately pushed aside the crowd and ran towards a blackboard in the corner.
Then as quickly as possible, he wiped the dust off the blackboard with his sleeves and quickly pushed it next to Xu Hao.
He also did not forget to give thoughtful reminders.
“Xugong, new blackboard!”
Xu Hao was slightly startled, nodded in greeting, pulled the blackboard in front of him, and continued writing.
The researcher saw Xu Hao happily accepting his small blackboard.
There was a look of joy on his face.
Xu Hao didn’t notice the expression on his face.
The same is true for Mr. Chen in front of the blackboard.
His eyes were fixed on what Xu Hao wrote on the blackboard.
at the same time.
He concentrated his attention and listened carefully to what Xu Hao said word for word.
Time is ticking and ticking, passing quietly.
Everyone in the laboratory seemed not to feel the passage of time.
Everyone stopped with bated breath, paying full attention, listening carefully to Xu Hao’s explanation and writing in front of the blackboard.
now.
Even though they have been studying this profession for several years, they have conducted hundreds of experiments.
But what Xu Hao is talking about now and what is written on the blackboard.
For a moment.
They actually feel a little obscure? ! !
This discovery shocked them all.
And when Xu Hao finished writing the last word, he capped the pen.
He turned around, breathed a long sigh of relief, and said with shining eyes.
“Mr. Chen, this is the opportunity I mentioned!”
“What do you think?”
After the words fell, Xu Hao looked at Mr. Chen.
At this moment.
Mr. Chen did not answer Xu Hao’s question immediately.
He looked at Xu Hao’s densely written formulas, materials and derivation processes on several blackboards.
As calm as he was, his body was trembling slightly at this moment.
His eyes flickered and his face trembled.
Looking at Xu Hao, he asked in an excited and hoarse voice.
“Xiao Hao…how sure are you?!…”
