I really just want to be a scholar

Chapter 718 See if such a person is qualified to continue to be a doctoral supervisor!
The crowd blocked the only way to enter the teaching building.

Qin Ke knew that Ning Qingyun, who was a bit of a clean freak, didn't like strangers getting too close, so he didn't take her to squeeze in to join in the fun, but stood a dozen steps away from the crowd, wanting to see what was going on first, and then decided to change The branch venue still waits for the crowd to disperse before entering.

But he just stood still for a while, when he saw two security guards twisting a young man with glasses and walking out from the crowd.

The young man with glasses was still struggling, and shouted: "I just want to go in and show off my academic achievements, I didn't make trouble..."

The security guard yelled: "It's reasonable for you to sneak in without a participation card? It also affects the order of the venue. If you want to participate in the exhibition, you should apply to the Physics Society in advance!"

Probably because he was poked at a sore spot, the young man with glasses suddenly lost his confidence.

At this time, there was a lot of low-pitched laughter from the surrounding crowd: "He's trying to fish in troubled waters again."

"That's right, I didn't have the qualification to participate in the exhibition and just sneaked in to take a look. Just now, I seemed to be pulling people to look at his posters. It seemed that I wanted to find someone to invest in. I really didn't know what to do. Are you expelled now? Sven sweeping the floor, Sven sweeping the floor, shame on grandma's house gone."

The face of the young man with glasses turned red all of a sudden, and he clenched his fists tightly, but as if he had thought of something, a look of pain flashed in his eyes, and his clenched fists relaxed again.He lowered his head and said in an almost pleading voice: "Brother Security, let me go, if I don't go in, can I just hold a poster outside here?"

Seeing that the young man with glasses softened his attitude, the security guard shook his head and refused: "No, in such a cold day, who is to blame if you freeze outside? Let's go, let's not affect the academic conference here. The problem is not something we little security guards can handle!"

Qin Ke almost knew what was going on when he heard this.

Each sub-venue has a booth, which needs to be applied to the Physics Society in advance. Only the Physics Society will arrange the exhibition area and distribute the exhibition badge if it considers that it meets the qualifications for participation.

The exhibition area is like a small booth. A good booth has a display screen that can play PPT, while a poor booth only has a small stool and a whiteboard that can be used to post academic posters.

In the annual physics academic exchange conference, not only experts, professors and even big names in the industry gather, but also many technology companies come to look for outstanding talents.

Therefore, for many newcomers in physics who are not well-known, it is very good to win a poster and whiteboard exhibition position. Maybe they can give people insight, find a good job or get sponsorship. Not everyone can stay in school as a lecturer, and not everyone can find a suitable and satisfactory job.

And this young man with glasses obviously missed the application period or failed to pass the approval, so he wanted to sneak in to try his luck, probably holding a poster in the venue and pulling people to publicize his research results, which affected the order of the venue, so he was patrolled The security guard "please" come out.

Qin Ke saw that the young man with glasses was less than 30 years old, and he was gentle, but his clothes were thin. He only wore a brightly colored old sweater and an old black suit of poor quality. His face turned blue and white from the cold. , the button of the old suit fell off under the tugging, and he looked extremely embarrassed and downcast, but he was always carefully protecting a rolled-up poster in his hand.

They are all colleagues who study physics. Qin Ke couldn't bear to see him shivering from the cold.When Qin Ke was a child, he used to brave the wind and snow with his father to buy goods. Thinking of his father loading and unloading goods by himself and sweating in order to save some money, it seemed to overlap with the downcast young man in glasses.Qin Ke felt sour, and said, "Two security guards, can you take him to the lounge over there first, and give him a cup of hot tea, so as not to freeze him to death."

Although it was not snowing at this time, it was freezing and snowy, and the outdoor temperature was only about minus 13 degrees Celsius. The young man with glasses was wearing thin clothes.

Seeing Qin Ke's sudden sound, the security guard and the young man with glasses looked over in surprise.

Qin Ke took off the sunglasses he was wearing, revealing his original appearance, and then held up the participation card worn in front of him: "I am Qin Ke, the special guest of this conference, and also the honorary professor of Beijing Institute of Technology, can I give How about me?"

The special guest is the top presence in the entire academic exchange conference. There are more than 3500 participants, and there will be no more than 30 special guests, not to mention that this person is the famous and well-known Qin Ke!

The security guards are all affiliated to the Security Office of Beijing University of Science and Technology, and they can be regarded as people who have half a foot in the academic circle. They recognized Qin Ke at a glance, and knew that he was indeed the honorary professor that the school had advertised. They hurriedly said respectfully : "It turned out to be Professor Qin, no problem, let's take him to the lounge of this teaching building."

The lounge is on the first floor, very close, less than 2 minutes walk.

Qin Ke took Ning Qingyun's little hand and followed him to the lounge.

The lounge is small, but it is also heated.

The young man with glasses drank two cups of steaming warm water, and his face, which was blue from the cold, slowly recovered.

At this time, he also saw Ning Qingyun, who was graceful, pure and charming after taking off his sunglasses, his eyes flashed with astonishment, but he only took a look, then quickly lowered his head and said gratefully: "Thank you, Professor Qin, Professor Ning!"

Qin Ke took the young man with glasses and looked at his poster while he was drinking warm water. At this moment, he just nodded with a smile, and asked, "Are you Luo Shouqing who is signed on the poster?"

"Yes, Professor Qin." Luo Shouqing quickly got up, adjusted his clothes and appearance, and replied with great respect.

He naturally knew the status of this extremely young boy in front of him in the physics world. He didn't feel contemptuous at all because Qin Ke was seven or eight years younger than him. It is a great honor to have a conversation with him in front of him—although Qin Ke has never been superior in Qingmu University, and it is easy for students to find him, but it is not easy for students and even scholars and professors outside Qingmu University to meet him. .

Qin Ke admired Luo Shouqing's attitude. He handed the poster to Ning Qingyun who was next to him for a closer look, and asked, "I see what's on your poster. Are you studying chemistry and physics?"

The so-called chemical physics is a science that studies physical problems in the field of chemistry, and is an interdisciplinary subject of chemistry and physics.

Luo Shouqing stood at attention nervously and replied: "Yes. My undergraduate and postgraduate studies are both in the Physics Department of Aurora University. The postgraduate major is 'Chemical Physics', mainly studying liquid structure, equilibrium state and transport theory. Statistical mechanics, constitutive thermodynamic properties of various states of matter, etc. "Electrochemical desalination" in the poster is the research subdivision direction of my Ph.D., and the research results on the poster are all completed by me."

It's a coincidence that Qin Ke secretly thought that electrochemical desalination is a new direction of seawater desalination, which is mentioned in the system's A+ level knowledge "A new type of high-efficiency, low-energy and fully automatic seawater desalination technology solution".

Although the title of "A New Type of Fully Automatic Seawater Desalination Technology Solution with High Efficiency and Low Energy Consumption" is a "technical solution", it is actually a huge and complex technical system, including photovoltaic wind tidal power generation, energy storage, and seawater desalination. A new type of seawater desalination technology system that integrates, in addition to the initial infrastructure and equipment needs to invest a lot of money, can basically achieve energy self-sufficiency in the future, no additional energy supply is required, at most, equipment and consumables need to be replaced , The cost of seawater desalination is very low.

In the part of seawater desalination alone, several new desalination methods are mentioned. According to different environmental conditions, one or more combinations can be selected for seawater desalination.

Among them is the electrochemically mediated seawater desalination scheme based on the Faraday effect, and "electrochemical desalination" is an important part of it.

Qin Ke wanted to study Luo Shouqing's level, so he pointed to the poster in Ning Qingyun's hand and asked, "The desalination performance indicators of different electrochemical desalination technologies mainly include applied current density, charge efficiency, influent concentration, electrode and System resistance, electrode porosity and other parameters, what are the desalination capacity, charging efficiency and thermodynamic efficiency of the membrane CDI mentioned in the poster, and how are they calculated?"

A trace of surprise flashed in Luo Shouqing's eyes: "Professor Qin, are you also familiar with electrochemical desalination?"

As the saying goes, "As soon as an expert makes a move, he will know if there is any." Qin Ke asked a very professional desalination performance index. This is at least a detail that only doctoral students in related majors can understand. How could Luo Shouqing not be surprised?
You must know that according to the rumors, Qin Ke is good at fluid mechanics and quantum mechanics in physics.

Qin Ke nodded: "It's relatively familiar."

Luo Shouqing didn't dare to be negligent when he was amazed. He vaguely knew that he was facing an unprecedented opportunity, so he answered seriously: "The desalination kinetics is controlled by the electrochemical process and the diffusion rate from the bulk electrolyte to the solid-liquid interface. , where the charge efficiency is calculated as the ratio of salt removed to charge put in..."

He took out a pen and paper, wrote a line of formula: "Fns/Qcharge", and explained: "F is Faraday's constant (26.801 Ah mol^(-1)), ns is the number of moles of salt removed in each half cycle , Qcharge is the total charge (Ah) accumulated during charging..."

He explained while writing, and wrote out the calculation formulas of more than a dozen indicators such as Coulombic efficiency, desalination completion speed, flow efficiency, and energy indicators, nearly half of which were not mentioned by Qin Ke.

Qin Ke asked a few more detailed questions such as "the mechanism of electrochemical desalination", "the relationship between the desalination ability of carbon electrodes and the charge storage capacity of carbon materials", "the principle of removing ions through charge compensation of redox active electrolytes", etc. , Luo Shouqing was able to answer in seconds, showing his outstanding talent in the direction of electrochemical desalination.

Qin Ke asked unexpectedly: "Your level is very good, and you also got your doctorate at Aurora University? Why can't you even apply for the poster booth of the Physics Society? No tutor to help recommend it?"

Generally speaking, poster display booths are prepared for doctoral students who are about to graduate, postdoctoral fellows who are being trained in postdoctoral stations, and Ph.D.s who have graduated less than two years ago, and young lecturers. The level is qualified, and most of the physics associations have passed the review. Giving a poster display booth is also a chance for newcomers to make their mark.

Qin Ke made a comprehensive judgment based on the content of the poster and the questions he asked just now. This Luo Shouqing's professional level is quite good, with a postdoctoral level, but it is a bit strange to see that he is so poor that he couldn't even apply for a display booth.

Hearing Qin Ke's question, Luo Shouqing's expression darkened, with a look of anger, unwillingness and embarrassment on his face, as if he didn't know how to speak. At this time, two officers from the Physics Society rushed over and asked respectfully: " Professor Qin, what happened? Do you need our help?"

They obviously heard the report from the security guards, fearing that Qin Kening and Qingyun would be dissatisfied with any accident, so they hurried over to deal with it.

"It's nothing. I just met this Dr. Luo. I thought I was a physics colleague, so I didn't ask a few more questions." Qin Ke shook hands with the two officers, then got up and said to Luo Shouqing:

"If you have any unspeakable secrets, forget it. I saw your poster, and you have a certain level. Don't give up on the path of physics. If you really have any obstacles, just contact me."

Qin Ke touched his pocket and happened to bring a stack of business cards prepared for today's meeting, so he gave one to Luo Shouqing.

The above is very simple, only "Qin Ke, Professor of Department of Mathematics and Physics, Qingmu University", e-mail address and office phone number. Although Qin Ke's mobile phone number is not a great secret, he will not give it to strangers casually.

Luo Shouqing was stunned for a long time. He had been stared at all these days, and it was the first time someone recognized him like this and showed him kindness. He only felt his nose sour and his chest hot.He didn't take the business card, just took a deep breath, and said desperately: "Professor Qin, I didn't study for my Ph.D. at Aurora University, but at South University of Science and Technology, but I dropped out before finishing my study..."

He told his past without reservation.

It turned out that Luo Shouqing also planned to study for a Ph.D. at Aurora University, but his graduate supervisor was not good at the field of "electrochemical desalination" that he was most interested in. He hesitated, and happened to meet a " Professor Qi Chengfu from South University of Science and Technology, who is a master in chemical physics, is very famous in the field of electrochemical sewage treatment, so he wanted to apply for the doctoral candidate of Professor Qi.

At that time, his supervisor didn't agree very much, and said that Professor Qi was more "strict" and "demanding" than others, but Luo Shouqing was full of confidence and believed that his level was high enough, so he insisted on applying for Professor Qi Chengfu's Ph.D. student, and eventually successfully passed the exam, becoming Qi Chengfu's student.

But after becoming Qi Chengfu's student, Luo Shouqing discovered that Qi Chengfu was usually very busy, and he didn't show up in the laboratory very much, let alone pay attention to his studies. At most, he gave a few pointers a month. , does not have much effect.Fortunately, Qi Chengfu's laboratory is well-equipped. Luo Shouqing spent more than half a year through self-study and self-research, and made many innovative achievements in the direction of "electrochemical desalination", and even wrote a thesis.

According to the regulations, he had to hand over his thesis to his supervisor for review before submitting the manuscript. Unexpectedly, after Qi Chengfu read his thesis, he hinted that he would write the first paper, and Luo Shouqing could only be the second author.

Luo Shouqing felt uncomfortable immediately. Even if Qi Chengfu asked for a corresponding author, he could bear it. After all, the experiment was done in other people's laboratories, but if he wanted to be the first author, he would be reduced to the second author, which had exceeded his bottom line.

You must know that almost all of his thesis was researched by himself, Qi Chengfu did not play any guiding role at all, and the first work is related to the ownership of subsequent technical patent achievements, and the second work has almost no income.

Luo Shouqing was unwilling, and Qi Chengfu became unhappy. After saying a few words to Luo Shouqing, Luo Shouqing was young and energetic, with a sense of arrogance in his chest, so he turned back on the spot, completely offending Qi Chengfu.

Qi Chengfu said at that time: "You don't want to graduate and get a certificate."

Luo Shouqing was dissatisfied and complained to the dean of the department. However, how could a doctoral student from out of town compete with a full professor?

Let Qi Chengfu handle it by himself, and the result can be imagined. Luo Shouqing has been completely isolated in the laboratory since then. He was aggrieved and angry, so he dropped out of school directly and planned to find another supervisor to study for a doctorate.

But the subdivision circle of "chemical physics" is neither small nor big. Qi Chengfu is still a well-known authoritative professor among them, and he is extremely influential. Naturally, Luo Shouqing's behavior of "betrayal from the teacher" will be completely rejected. He "banned" him in various ways, and no professor was willing to take him as a student at the risk of offending Qi Chengfu, and even his graduate tutor at Aurora University had no choice but to do anything about it.

Luo Shouqing's family was not rich, so he could only find a job after he could not study for a Ph. D., but it was not easy for him to find a good job with a postgraduate degree.

Luo Shouqing borrowed from relatives and friends but couldn't get together the huge sum of money. He was at a loss what to do when he overheard someone talking about the year-end academic exchange meeting of the Physics Society, so he wanted to apply for a display booth to display his research results. Can you sell it for a good price, even if you can't sell it, take the opportunity to find a good job, and advance ten years' salary from the company to treat your family members.

But he only has a postgraduate degree and has no recommendation from his supervisor. How can he pass the threshold for the booth review of doctoral students?He really had no choice but to sneak into the branch venue to promote, but was expelled by the security...

Qin Ke has been paying attention to his expression, and can judge that what Luo Shouqing said is probably true, and he has real talents and lessons.

Seeing that Luo Shouqing was really cornered, Qin Ke didn't mind extending a helping hand, and said, "If you want, you can work in the laboratory under Lime Technology, as long as the company verifies that what you just said is true, Your family’s surgery expenses can be covered by the company’s critical illness funding fund for employees’ families, so don’t worry.”

Luo Shouqing was completely stunned, the happiness came so suddenly, not only the work was settled, but also the money for the family's medical treatment was settled, his eyes suddenly became moist, his lips moved, but he couldn't say a word.

An officer of the Physics Society quietly pulled Razinke's clothes, and whispered: "Professor Qin, that Professor Qi Chengfu has a lot of influence in the circle, if it's not necessary..."

He didn't see the process of Qin Ke studying Luo Shouqing. He was afraid that Qin Ke would offend a big player in the industry just because of Luo Shouqing's one-sided remarks, so he kindly reminded him.

"Thank you. But..." A sharp light flashed in Qin Ke's eyes: "Professor Qi Chengfu... I remember that he has a special report on the third day. I am not qualified to continue to be a doctoral supervisor!"
