Computational Materials Laboratory of Jinling University.

Looking at the translucent cube, the black cylinder that was gradually shaped under the guidance of the blue light beam, Lu Zhou said in a rather emotional tone.

"When I was at the Jinling Institute of Advanced Studies, I discussed with Dr. Hou and Deputy Director Yang how to synthesize sg-1 superconducting materials stably. Vice Director Yang smoked an afternoon smoke in the corridor ... … Finally, guess what we did? "

At this moment, the half-height device in front of him is the molecular-level 3D printer at the core facility of the Institute for Computing Materials.

Unlike the popular home 3D printers on the market, this thing is great because it can independently set the spatial order of atomic stacks within a certain accuracy range, and even adjust the energy of chemical bonds.

This means that no matter whether molecules exist in nature, as long as they can exist logically, they can be "printed out" in batches through this stuff.

How powerful this device is. Luzhou can't think of a suitable vocabulary for the time being, just as few people can accurately describe how powerful his hyperspace theory is.

But there is no doubt that if this thing is taken to the 21st century, materials scientists, biologists, and medical scientists around the world will be afraid to go crazy ...

Standing next to Lu Zhou, the young doctoral student who demonstrated a molecular 3D printer for him asked inquisitively.

"How did you solve it?"

"Vapor deposition method," Lu Zhou smiled, and then said, "I don't know if I'm not going to do this now, but the only way we could think of at that time was to bake layer by layer like a pancake. The graphene six-grid, stacked at an angle of 1.1 °, formed a Mott insulator between the cross sections of each layer, and found the 'semi-filled' structure we dreamed of. "

Said the young doctoral student.

"That's too ... too much."

He originally wanted to talk about trouble, but he always felt a little impolite.

Looking at the expression on the young man's face, Lu Zhou continued with a smile.

"... The technical route of the vapor deposition method is locked, and the road behind is slightly smoother. We tried to improve the method prepared in the laboratory and cooperated with engineers from Baosheng Group to explore the method of industrialized mass production. Even so, the cost is only 'acceptable' relative to strategic industrial facilities such as controlled fusion cores. "

"In the past, an idea in scientific research required rigorous demonstration and tedious design experiments before it could be tested. However, the cost of verifying an idea is only 1 hour and 10,000. The cost of credit. "

"The technology in this era is really beyond my imagination."

Hearing the compliments of the ancestor of computational materials science, the doctoral student scratched his head a little with embarrassment.

"In fact, it's not as exaggerated as you said ... there are too many scientific researchers in pan-Asian cooperation, our funding is very limited, and in fact, there are not many opportunities to try. And most of the more novel materials have just been developed in molecular printing When it came out, it was almost dug out. Now, if we want to make new results, we still have to pass rigorous calculations and design. "

Lu Zhou smiled and shook his head.

"It's a happy complaint."

"Be content, child."

Hearing this "child", the doctoral student's expression was a bit subtle.

Although this big man is from a hundred years ago, he doesn't look much older than himself.

Regardless of the feelings of the 22nd-century young man, Lu Zhou looked at the translucent cube in front of him and said.

"I already understand the basic situation. I want to verify some ideas here. Go out first."

"Will you use the equipment here?"

Lu Zhou said with a smile.

"You look down on me. Before I entered the laboratory, I did some homework beforehand."

"You said that, how dare I look down on you ..." The doctoral student embarrassedly touched the back of his head. "I just worry about you and won't operate these new devices. But if you insist, I won't be there for you . "

Then he walked to the door.

But at this moment, Lu Zhou called him from behind.

"Wait."

Hearing Academician Lu's voice, the doctoral student stopped and cast a question to him.

"What's matter?"

Lu Zhou smiled and said.

"Can you pour me a cup of coffee if it's convenient? It's just good."

...

What surprised Lu Zhou was that there was no such thing as instant coffee. Either a coffee machine or a canned, bottled, or bagged coffee drink from a convenience store.

People in this era don't seem to like boiling water very much. Although dry powdered beverages do not leave the stage of history, they have become a rare thing. Few people deliberately prepare them at home or in the office.

Taking a bite of frowning black coffee, Lu Zhou put the cup on the table, then took out a pen-sized memory card, and gently placed it on the laboratory holographic computer host.

With the bright blue light beam, Xiao Ai's holographic image quickly appeared in front of him.

"The laboratory took over successfully! Now it is Xiao Ai's! Φ (≧ ≦ *)?"

Looking at the little guy jumping up and down restlessly in the holographic beam, Lu Zhou ordered.

"Don't do anything, we just borrow the equipment here and return it when we run out."

Xiao Ai: "Understand! What does the host need Xiao Ai? (??????) ??"

Lu Zhou did not answer immediately, but took out an orange-yellow metal ball about the size of a fist from his arms, and then placed it gently on the table next to it.

Kill the core.

This is the original memory of the "Pvt.

Although his gut tells him that this stuff is dangerous, he still wants to try it out.

After all, this is from the super-civilized technology that once completed the wonders of the circular world ...

"I have something here that needs to be analyzed."

...

Entrance to the Computational Materials Laboratory.

The doctoral student who had just come out of the laboratory was hesitating whether to go to the library to pass a while, and saw President Cai and Dean Zhou of the Material Institute and walked in with a ticket.

His face changed instantly. Thinking of Dean Zhou's previous instructions to himself, the doctoral student turned around and wanted to leave. As a result, Dean Zhou saw it sharply.

Calling his name from a distance, Dean Zhou stepped up and stared at him anxiously.

"Why did you come out alone? Academician Lu?"

"... Lu, Academician Lu is still inside," said the doctoral student, and he threw the pot away. "He asked me to come out."

Dean Zhou stomped his feet anxiously, glaring at him.

"Did I not let you follow him? How could you leave him alone!"

He wasn't worried that Academician Lu would torture his precious instruments ... well, actually, he was a little worried. But what he was most worried about was that Academician Lu hurt himself.

Although 3D molecular printers are not dangerous, some unstable products and incorrect operations may cause a series of serious consequences, including explosions.

Although similar things haven't happened in Jinling University, they have happened in the university next door.

An intern introduced the wrong model into the 3D molecular printer in the wrong way, creating a group of extremely unstable, chain-like cho compounds. This compound exists in natural environment for less than 1 millisecond, and quickly decomposes into ch4, co and oxygen, and a lot of heat.

The final result is said to be that the intern not only blew himself up, but the entire building was smoky.

Because of this, the next-door university did not produce a handy computational material dissertation last year, and the entire school was taken to a safety education class.

A frozen person from the 21st century, no matter how much work he has done before, the operating experience of experimental equipment in this era is infinitely close to zero.

Letting such a person stay in the laboratory is no different than throwing a cigarette **** into a gasoline tank.

Looking at Dean Zhou who was angry at the students there, Principal Cai spoke aside and said.

"Lao Zhou, don't be too embarrassed about this child. It was Academician Lu who asked him to go out. Can a doctoral student turn his back on it? Think about it in other places."

Although he understood the reason, Dean Zhou shook his head and said angrily.

"Prank, it's prank!"

After persuading Dean Zhou, Cai Mingrui looked at the doctoral student and continued in a gentle tone.

"I don't blame you on this matter. You just have to take us over to find Academician Lu."

Seeing that the principal released the siege for himself, the doctoral student finally relieved and nodded quickly.

"Okay, no problem, please follow me!"

After the group entered the institute, they quickly came to the door of the laboratory.

The doctoral student stepped forward and pressed his fingerprint on the code lock.

However, something unexpected happened.

I saw the door lock flash a red light, and the door stood still.

Seeing the word [lock] appearing above the door handle, the doctoral student gave a slight whisper, whispered "strange", and then tried again.

The results were the same this time.

The door didn't move at all.

Unable to wait, Li Guangya, who had been patient and did not speak, finally couldn't help anxious to say.

"What's going on? Don't you go in yet?"

"I don't want to go in ..."

The expression on his face was full of embarrassment. The doctoral student standing at the door looked embarrassedly and looked back at Dean Zhou and Principal Cai behind him, swallowed and continued.

"door……"

"It seems locked from the inside."
