The day after the end of the bidding meeting.

It's the same big hall.

Standing in front of the auditorium, Lu Zhou brought a lecture on computational materials science to the students of Harbin Institute of Technology with a loud and steady voice.

“…… The advantage of computational materials science is that we can avoid many unnecessary mistakes through calculation, and get rid of the traditional scientific intuition and use a more rational vision to find the answers we need. ”

"Taking the theoretical model of electrochemical interface structure as an example, I will briefly elaborate on the application of mathematical theories such as functional analysis in the field of computational materials science......"

The audience was black, shoulder to shoulder, and there were even people sitting on the ground.

After hearing the news of this report, not only the students of Harbin Institute of Technology and nearby universities, but even some researchers engaged in the Institute of Materials who have graduated for many years and worked in nearby research institutes also rushed here.

In order to maintain order at the scene, Harbin Institute of Technology dragged almost half of the people in the security office over. Although this report will cause a lot of trouble to the teachers here, I am still quite happy to see the expression on Academician Zou's face.

In order to respond to their enthusiasm, Lu Zhou also took out twelve points of spirit and devoted himself to this lecture.

The theoretical model of the electrochemical interface structure that he is talking about today has caused quite a stir in the field of computational materials science and surface chemistry, for which he has been awarded the Hoffmann Medal by the German Chemical Society and jointly nominated by several Nobel laureates.

Both the theory itself and the mathematical methods he expounded in the lecture are quite enlightening for a scholar engaged in materials science research or applied mathematics research.

Therefore, the people who sat in the auditorium and listened attentively.

Whether you can understand it or not, you will definitely take notes on important places.

Whether it's a student or a professor.

Whether it's from the chemical institute or from the number of courtyards that come to join in the fun......

The lecture lasted from 10 a.m. to 1 p.m.

The lecture, which was scheduled to end at half past twelve, was delayed for half an hour, but less than ten people left the table in the middle of the lecture.

As the lecture ended, the entire auditorium was filled with thunderous applause, almost toppling the entire roof.

Looking at the teachers and students in the audience, Lu Zhou smiled and nodded in thanks, and then walked off the stage.

After speaking all morning, not only the listeners were hungry, but the people who spoke on the stage were also hungry with their chests and backs.

Following in the footsteps of the reception staff, Lu Zhou moved from the auditorium to the school's cafeteria.

In the faculty dining area on the top floor, the school prepared a table for him.

"Professor Lu, I salute you for the students of Harbin Institute of Technology! Thank you for this wonderful lecture to our students of Harbin Institute of Technology! ”

"Academician Zou is polite," and after clinking glasses with Academician Zou, Lu Zhou smiled modestly and continued, "I wonder if it is convenient to take me to visit your laboratory in the afternoon?" ”

"Oh, I almost forgot," Academician Zou patted his head, smiled and said, "It's easy to say, Professor Lu is so interested in my research, of course I warmly welcome it!" When this lunch is over, I'll take you there! ”

Lu Zhou smiled and said, "Thank you, you are so polite." ”

After a full meal, the group left the cafeteria.

Walking on the tree-lined path to the laboratory, Academician Zou asked with a smile.

"What do you think of the environment at Harbin Institute of Technology?"

Looking beyond the shade of the trees on the side of the road and looking at the library not far away, Lu Zhou smiled and said.

"It's a university with a strong engineering atmosphere."

"After all, what we cultivate are talents in the field of national defense in the future, and engineering majors are also the strength of our school." Speaking of this, Academician Zou paused for a moment, continued to smile and said, "If you have the opportunity, I hope that Professor Lu will come to our school to hold some more lectures." ”

Lu Zhou smiled and nodded.

"Definitely."

Along the way, Academician Zou did not invite Lu Zhou to stay and teach, after all, he also knew that it was not realistic.

didn't even take the olive branch thrown by Yan Da and Mizuki to heart, compared to Harbin Institute of Technology, the top nine weak people who were almost "expelled from C9", they really didn't have the confidence to invite this great god. It's good to be able to make a good relationship and invite him to come over and give a few lectures.

At least in terms of the level of the lecture just now, even Academician Zou himself listened to it, and he benefited a lot.

Soon, the group came to a building more than six stories high.

After passing through the curfew, Academician Zou took Lu Zhou into the laboratory.

"That's what I'm talking to you about, about the biomimetic prosthetics lab, including my HA/Ti biocomposites project team, working in it. And the research team from Aurora University, they come here occasionally to communicate with our project staff. Of course, they're mainly responsible for the neural interfaces, and we're responsible for solving the material and mechanical problems...... Here it is. ”

Pushing open a door, Academician Zou walked into the laboratory with Lu Zhou.

Noticing the movement at the door, the two researchers standing next to the experimental equipment couldn't help but turn around.

When they saw Academician Zou who appeared at the door, the two were about to say hello, but soon they noticed Lu Zhou standing next to Academician Zou. One of the bespectacled researchers suddenly had a surprised look on his face, and then he took two excited steps forward and spoke.

"You...... Are you Lu Zhou? ”

"Hmm...... It's me," was a little embarrassed by this guy's enthusiasm, but Lu Zhou still smiled kindly, "I won't disturb your work here." ”

"No, no, please sit down, I'll make a cup of coffee."

"No, no, no, no, I just followed Academician Zou to visit, and I won't stay long."

Finally calmed down the excited researcher, Lu Zhou followed Academician Zou to the laboratory, and soon saw a pair of arms full of mechanical texture in a transparent container about one or two meters long and wide, mounted on a circular metal base.

Looking at this mechanical arm, a look of interest appeared on Lu Zhou's face.

"Can this thing move?"

Academician Zou said with a smile.

"Of course, although there are still some things that need to be adjusted, it is basically still usable...... Want to try it? ”

"Please let me feel it."

The device used to control the arm is a hollow metal ring about the length of a thermos cup. After breaking the ring from the side, Lu Zhou put it on his arm like a fencing armguard.

Under the adjustment of the bespectacled researcher, Lu Zhou soon felt a slight tingling pain in the elbow joint, but soon he couldn't feel it. At this point, two tiny probes have pierced into the muscles and begin to collect nerve signals from the arm to the forearm.

"Is it okay?"

"It's already okay," he knocked a few buttons on the computer next to him, and a line that fluctuated up and down like an electrocardiogram appeared on the screen, and the researcher who straightened up again looked at Lu Zhou and said with a smile, "You try to swing your fist." ”

As he said, Lu Zhou tried to swing a punch forward.

Then, a magical scene happened.

The arm that was supposed to be swung forward did not move, or rather, it only shook slightly against the corner of the clothes. Instead, the mechanical arm mounted on a circular base, about four or five meters away from him, awkwardly swung a punch forward at an even speed.

Seeing this scene, the look of interest on Lu Zhou's face became more and more intense, and he glanced at his "unconscious" arm.

“…… Is it blocking the transmission of nerve signals? ”

As he spoke, he tried to pinch the palm of his right hand with his left hand.

emmm……

The pain is still there.

That's weird!

The researcher standing next to him made a helpless expression, "It's more interference than blocking, after all, this thing is only used to collect experimental data, and it's not a mature technology...... In fact, as long as your nerve cells are active enough to be able to lift your hands, you will feel a little tired at best, as if you have just finished 50 kilograms of anaerobic. ”

"I probably can't do 50 kilograms of aerobic ...... However, very interesting invention. Lu Zhou tried to do a few more sets of movements, some of which could be restored, and some of which were only twitched twice.

It seems that the technology is still quite immature, as the researcher said.

However, even so, the potential of this technology is considerable.

Unlike exoskeletons, which amplify human movements, this device can operate mechanical devices far away from the human body without the need for human movement, relying only on the conversion of neural electrical signals and digital signals.

If this technology can be developed and matured, it will not only be able to show its strength in the field of medical devices, but also play an unexpected role in many special fields!

Academician Zou shook his head and said: "It's not an invention, the neural bypass system appeared in Nature as early as April 16, and our project can be regarded as a branch study of the system." As far as I know, MIT is probably at the forefront, and it has already achieved some results. Rather, it's our side that is the catch-up. ”

"It doesn't matter who is the chaser or the leader," taking off the equipment, Lu Zhou touched the two tiny pinholes in his arm, "It would be nice if it could be connected painlessly...... This thing is quite deep. ”

The researcher standing next to him made a helpless expression.

"There is no need for this at all, this is originally for amputees, and they are generally not taken off casually."

Lu Zhou smiled and said: "I think that the applicable people of this technology do not necessarily have to be confined to amputees, if you install a thing at the spine, wouldn't it be able to remotely operate a whole robot?" ”

Academician Zou smiled and said, "Your idea is quite interesting, but I am afraid it is not an ordinary difficulty to implement. Not to mention that the signal processing of spinal nerves is more than 100 times more complex than that of trunk nerves, this kind of nerve center, which is related to the health and comfort of the whole body, cannot be experimented on casually. ”

Lu Zhou nodded thoughtfully.

"That's right."

Returning the equipment to the researcher, Lu Zhou took a spin around the lab.

When he was about to finish shopping here, Lu Zhou, who had walked to the gate of the institute, suddenly stopped and looked at Academician Zou next to him.

"By the way, Academician Zou, I still want to ask you one more thing."

Academician Zou asked, "What's the matter?" ”

Lu Zhou smiled embarrassedly.

"You guys have this project...... Is there still a shortage of people? ”
