International students returning to 90

"In the first priority, [-] kinds of materials, [-] kinds except the sputtering performance test, the rest of the tests meet the latest requirements of NASA." When Tony saw the results of this report, he jumped up.

He forgot the terrible number 480, and stared at the [-] with joy.

"Lin, even if our experiment fails this time, we can sell these eighteen materials to Ford." Tony said with a smile.

He really treats the auto giant as a garbage recycling bin.

"These materials can only be successfully compounded under hot pressing and sintering. The cost is too high and there is no market value." Lin Yi was called a "merchant-style scholar" in his previous life, and he knew whether there was market value at a glance.

Tony nuzzled, "I'm not researching pressureless sintering, one day..."

"One day, you will be able to successfully graft roses and peonies with your pressureless sintering, but now, it's time for us to start sputtering performance testing."

The sputtering performance test needs to simulate a vacuum environment. When Professor Logan received a call from Tony, his glasses almost fell off.

"So soon, the sputtering performance test is done?"

"Professor, I have a hunch that we will succeed this time, please send the key here quickly, no, I will come to your house to get it!"

Hearing the sound of Tony starting a car on the other end of the phone, Logan immediately stopped him and said, "No, no, I'll come over, I just happened to see your progress."

Rogge drove out in a daze, thinking about the feasibility report that Simpson showed him a few days ago.

At that time, Simpson did not tell him who the owner of the feasibility report was. When he saw the experimental test results, he couldn't help but gasped.

"This data is not fake, if it is true... Simpson, we have witnessed the arrival of a new energy era!"

"The slow development of the solar photovoltaic industry is because the conversion efficiency of solar cells on the market is too low. Even in the best new energy laboratory, the known optimal cell conversion efficiency is only 20% higher than that on the market. But the cost has been greatly increased, so it is not feasible in the market at all.”

"But the data in this thing is 50.00%! It increases the conversion efficiency of solar cells by 50.00%, and the cost is actually lower than the market! How is this possible!"

Logan was panting heavily. Even though his research direction was not in the area of ​​new energy, but as a scholar in the field of materials science, he naturally knew the significance of this report.

"If this feasibility report is true, it will disrupt the entire energy industry." Simpson made the closing statement.

"Logan." Professor Simpson came out from behind the desk. He walked to Logan and said in a very soft voice, "You are, shouldn't there be some changes in the Simpson laboratory?"

Logan was shocked in his heart. Looking at the old leader, he saw the light he was familiar with in Simpson's eyes. The hawkish scholar, thinking of the scientific research community's evaluation of his boss, he took a deep breath, "What do you mean? yes……"

"If he can make some achievements in this experiment, I plan to let him try."

"Him?" Luo Genzhanger was puzzled, could this report be written by an acquaintance?

Allen?Michelle?Big names in the field of new energy materials appeared in Logan's mind, but that's not right, Alan, Michelle, Simpson asked them to try?They try to use Simpson's consent.

"It's the Chinese, Lin Yi." Simpson said the word Lin Yi in Chinese with difficulty.

Logan was silent, "Um, then, is this report a little watery?" He didn't directly say that the report was fake, he had already taken his boss's feelings into consideration.

For Simpson's obsession, Logan's old friends are aware of it.Those top laboratories in the world, their own industry, how can it be so easy.

Moreover, such a large piece of cake is simply not something that Simpson's laboratory can swallow.

"For us, the new energy center itself is idle. At most, a little money will be allocated to him from me, which will have little impact on us."

After hearing the words, Logan stopped talking. He could tell that Simpson had already made up his mind.

So... is that Lin Yi really capable?That's why Luo Gen got up early that day to take a look at Lin Yi, out of curiosity.

"Sting." The tire rubbed against the ground, making a screeching sound.

"FUCK, you don't have eyes when driving!" A young man with dreadlocks scolded Logan's car loudly.

Logan got out of the car and apologized repeatedly. Seeing the young man walking away, he wiped the sweat from his brow. Hey, his old heart is not scared.

By the time Logan drove to the laboratory, Qiao Sen and Andri had already been sent to wait at the door.

"Joseon, Andri? You participated in this experiment?" Logan is still very competent as the laboratory steward. Tony doesn't know Joson and Andri, but he can call out the names of these two little assistants. name.

"Yes. Professor Logan, Researcher Bryce asked us to wait for you here." Johnson said.

"The Hall thruster channel is a big project. It is rare to have the opportunity to participate, so cherish it." After talking about the scene, the three walked towards the Department of Aeronautics and Astronautics.

He Qun is hot-pressing and sintering the [-] kinds of materials with the second priority, while Tony and Lin Yi are going to test the sputtering performance of the first priority. The [-] kinds of materials with the first priority perform well under other tests. This greatly enhanced their confidence.

"Professor Logan, you are finally here!" Seeing Logan, Tony and Lin Yi immediately greeted him.

"Are you going to conduct a sputtering performance test?" Logan still couldn't believe it.

Tony proudly handed the information at hand to Logan, "Professor, see for yourself whether we can conduct a sputtering performance test."

Logan looked at him suspiciously, then opened the file, and when he saw the test results, his eyes widened in surprise.

The sample selection is very representative, the priority judgment is well-founded, the logical thinking is very clear, and the most important thing is data screening. This kind of screening ability is absolutely impossible without rich experience.

He couldn't help turning his eyes to Lin Yi.

Lin Yi nodded politely.

It really made them dig a treasure. Logan's heart was beating wildly. He decided to tell Simpson when he went back today that he could break ties with Horn and never return him to him!

"Come on, let's go to the laboratory on the sixth floor!" Logan said decisively.

The Plasma Technology Advancement Laboratory on the sixth floor occupies an entire floor alone because of its large footprint.

When the door is opened, the first thing that catches the eye is the huge large vacuum tank with a diameter of 1.8 meters and a length of 5 meters, with a built-in SPT100 Hall thruster.

"This is provided by NASA, and it can almost completely simulate the ion sputtering process. You do it, and I will watch." Logan said while secretly looking at the experimental design in Lin Yi's hand.

Lin Yi noticed Logan's gaze, and couldn't help being dumbfounded. He handed a copy to Logan, "Professor, help me check it out."

Logan blushed, coughed dryly, and looked up in style, materials science and engineering, at Simpson, Professor Simpson is good at materials science, while Logan focuses on materials engineering, so he is the person in charge of the Ford Center .

To be honest, he can understand this kind of thing, let him see his opinions, let him forget it.

"Well, it's very good. The thinking is very clear and the feasibility is very strong. Let's start." He boasted a few words solemnly.

Lin Yi was not polite to him, and went directly to operate.

"The sputtering energy is 300eV, the sputtering time is 2 hours, the sputtering distance is 75 cm, and the working medium is Xe. Is there any problem?"

"No."

"No."

"No."

Everyone responded.

Logan also noticed that this experiment was completely led by Lin Yilai, a newcomer in material science?Go to hell.

After determining the experimental parameters, several people started to operate.

The ceramic sample is cut into a cube with a size of 13.5 mm and a thickness of 4 mm. After spraying gold, it is placed on a designed rotating target platform.The rotating target stage has been placed by Lin Yi at a position 75mm away from the vacuum tank and the plasma engine.

The 75 mm was measured by everyone present with a ruler, including Professor Logan who joined in the fun.

After ensuring that the ceramic samples were in vertical contact with the Xe gas plume, everyone retreated to a safe position.

"The bombardment time is 1-4 hours, He Qun, record the data."

"Okay!" He Qun took a deep breath, the plasma engine, this is already a very high-level instrument, and domestic scientists rarely have access to it, and he is a sophomore, He Qun felt that the The pride value has increased a little bit.

When the plasma engine is working, it can be described as beautiful. The blue light is in the form of a ring, appearing in the dark simulated vacuum environment, and it feels like a dream.

"The principles in nature are indeed the same. The more beautiful things are, the more dangerous they are." Tony said with emotion, "The same goes for women."

Lin Yi and everyone...

Since there are [-] kinds of materials and only one plasma engine, the experiment lasted longer.

The X-ray diffractometer was directly moved to the sixth floor for phase analysis of the ceramic samples before and after the sputtering test.

"The acceleration voltage is 40KV, the scanning range is 10-90 degrees, the current is 80 mA, and the scanning speed is [-] degrees per second." He Qun reported the experimental design parameters, which was surprisingly smooth, and everyone including Professor Logan looked at him several times .

It was precisely these few glances that successfully made He Qun's children degenerate into a quail state again.

Made with the same material, Professor Logan seemed a little drowsy, but his feet were still sticking to the ground persistently, and sometimes he would glance at Lin Yi from time to time, and after a glance, he could stay awake for a few minutes, as if Lin Yi was Like his doping.

"No, the micro-region has a rough surface and fails."

"Neither this one."

"fail."

Standing down in one day, all six materials failed.

Professor Logan glanced at Lin Yi with some regret, and patted him on the shoulder, "The research on new materials is a long-term process. Young people are impatient, but God has a slow temper."

As he spoke, he walked slowly downstairs, while whistling, he was actually in a good mood.

The back waves of the Yangtze River push the front waves, so the front waves must be a little psychologically unbalanced, Logan thought.

"Have dinner, and then proceed to the last material test of the day." Lin Yi glanced at h-BN/Sio2, which was the fifth priority, and suppressed the urge to call Professor Logan back.

"Do you still eat instant noodles?" Qiao Sen asked weakly.

Lin Yi glanced at him, "Maybe you guys would like to eat hamburgers more?"

Qiao Sen... or instant noodles.

Sitting in a spacious and luxurious restaurant, eating instant noodles, who told the chefs to go to the Christmas holiday.Whether you're Hall Thruster Tunnel or some other major space program, not even America's return to the moon can stop Simpson's chefs from taking vacations.

So from the Christmas break to now, they ate hamburgers for four days, instant noodles for two days, and other things, and they don't want to remember anymore.

"I'm done eating, I'm going to turn on the machine." After taking two bites, Tony couldn't bear to embarrass his stomach, so he offered to turn on the machine.

The plasma pushing technology laboratory also needs to wear protective clothing. This one-piece protective clothing needs to be unbuttoned every button. It takes more than half an hour to put on the clothes alone. This is one of the important reasons why people are unwilling to eat.

Of course, the key reason is that the food is not good.

"Together."

It was still the same experimental procedure. Compared with the daytime, everyone was more interested in chatting, and the chatting content revolved around Professor Logan and Lin Yi.

"Lin, if Professor Logan and his wife are not very affectionate, I would have thought he fell in love with you. You didn't see his appearance during the day, his eyes were obviously about to close, and when he glanced at you, he opened them wide again .”

Lin Yi...

The blue light slowly went out, "Okay." Tony said with a smile.

He Qun did the XRD diffraction pattern as in the daytime.

"Lin, you are Chinese, right? Professor Logan should also be a purebred American. You say..."

"Success...success!" He Qun's voice sounded like a mosquito, but everyone heard it.

Be...successful?How is it possible, this is only the first day, the fifth material, how could their luck be so good?

How could their luck be so good!

Four people, eight pairs of green eyes stared at the diffraction pattern on He Qun's hand.

He Qun was uncommonly unafraid. He stumbled and said: "It can be seen from the diffraction pattern that during the preparation process of h-BN/Sio2, the fused silica part has undergone crystallization, and cristobalite has been formed. The phase of the composite material before and after sputtering has no The apparent change suggests that it remained relatively stable during the sputtering process."

He announced the result almost recited.

Tony snatched the diffraction pattern from his hand, "Joan, no, no, Jose Andri, do XPS pattern analysis immediately! Immediately!" He almost shouted out.

"Where is the scanning electron microscope! Bring it up, I want to see the surface morphology immediately!"

"No, no, no, don't move, I'll go down, I'd better go down sooner." Saying that, she took the sample and ran to the stairs, which meant that she didn't even take the elevator.
