The crowd blocked the only way to enter the teaching building.

Qin Ke knew that Ning Qingyun, who was a bit mystical, didn't like strangers getting too close, so he didn't take her to squeeze in and join in the fun. He just stood a dozen steps away from the crowd, wanting to see what was going on first, and then decided to change

It is better to wait for the crowd to disperse before entering the branch venue.

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

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

The security guard yelled: "How can you be justified in sneaking in without a participation card? It will also affect 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 in a sore spot, the bespectacled young man suddenly lost his confidence.

At this time, there were many low-pitched sneers from the onlookers: "Another one who wants to fish in troubled waters."

"That's right, I just sneaked in and took a look without the qualifications to participate in the exhibition. Just now, he seemed to be asking people to look at his posters. It seemed that he was looking for people to invest. He really didn't know the bounds of the world. Now he has been expelled? Sweeping the floor politely, sweeping the floor politely. He was embarrassed and was thrown into grandma's house.

Already."

The bespectacled young man's face turned red all of a sudden, and he clenched his fists hard, but as if he 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 Guard,

Let me go. If I don’t go in, can I just hold up the poster and display it outside?”

The security guard saw that the bespectacled young man had softened his attitude and his attitude became a little better, but he still shook his head and refused: "No, in such a cold weather, who cares if you freeze outside? Let's go, let's not affect the academic conference here.

The problem is not something that little security guards like us can handle!"

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

There are booths in each branch venue, and you need to apply to the Physical Society in advance. Only when the Physical Society deems it qualified to participate in the exhibition, it will arrange a display area and issue exhibition certificates.

The exhibition area is like a stall. The good stalls also have a display screen and can play PPT, while the poor stalls only have a small stool and a whiteboard where academic posters can be posted.

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

Therefore, for many newcomers to physics who are not well-known, it is good to get a poster and whiteboard exhibition space. Maybe they can help others to find good jobs or get sponsorships. After all, there are so many physics graduates every year.

However, not everyone can stay in school as a lecturer, and not everyone can find a suitable and satisfying job.

This young man with glasses obviously missed the application period or failed to pass the review, so he wanted to sneak in and try his luck. He probably held up posters in the venue and solicited people to promote his research results, which affected the order of the venue, so he was patrolled.

The security guard "invited" him out.

Qin Ke saw that the bespectacled young man was less than thirty years old. He was well-mannered, but his clothes were thin. He only wore a brightly colored old sweater and an old black suit of poor material. His face was so cold that he turned blue and white.

The buttons of his old suit fell off after being pulled. He looked extremely embarrassed and miserable, but he always carefully protected a rolled-up poster in his hand.

They were both colleagues studying physics. Qin Ke couldn't bear to see him shivering from the cold. When Qin Ke was a child, he followed his father in the wind and snow to buy goods. He thought of his father pretending to be himself in order to save some money.

The unloading of goods, sweating heavily, seemed to overlap with the figure of the destitute young man with glasses in front of him. Qin Ke felt sour and said: "Two security brothers, can you take him to the lounge over there first and give him to me?"

He brings a cup of hot tea, but don't let the person freeze."

Although it wasn't snowing anymore, it was still freezing and the outdoor temperature was only about minus 13 degrees Celsius. This young man with glasses was wearing thin clothes and he might get seriously ill if he stayed in the cold for a long time.

Seeing Qin Ke suddenly making a 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 true appearance, and raised the participation certificate in front of him: "I am Qin Ke, the special guest of this meeting and an honorary professor of Beijing Institute of Technology. Can you give me some advice?

Do you want me to save face?"

Special guests are the top presence in the entire academic exchange conference. There are more than 3,500 participants, and there will be no more than 30 special guests, not to mention that this person is Qin Ke, who is well-known to women and children!

The security guards were all affiliated with the Security Office of Beijing Institute of Technology, and they could be considered as people who had only 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 promoted so much, so they hurriedly said respectfully.

: "It turns out to be Professor Qin. No problem. We will take him to the lounge of this teaching building right now."

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

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

The lounge is not big, but it is also heated.

The bespectacled young man drank two cups of hot boiled water, and his face, which was turning blue from the cold, slowly calmed down.

At this time, he also saw the graceful and pure Ning Qingyun after taking off her sunglasses. His eyes flashed with surprise, but he only glanced at it twice before he quickly lowered his head and said gratefully: "Thank you, Professor Qin.

Professor Ning!”

Qin Ke took the bespectacled young man's poster and read it over while he was drinking warm water. At this time, he just smiled and nodded, and then asked: "Are you the Luo Shouqing signed on the poster?"

"Yes, Professor Qin." Luo Shouqing stood up quickly, straightened his clothes and appearance, and answered with great respect.

He naturally knew what kind of status the extremely young boy in front of him had in the world of physics. He was not at all scornful just because Qin Ke was seven or eight years younger than him, and even because he could meet such a big shot and have the opportunity to work in

I feel extremely honored to have a conversation in front of him - although Qin Ke has never been aloof at Qingmu University, 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.

.

This chapter is not over yet, please click on the next page to continue reading! Luo Shouqing's attitude made Qin Ke appreciate it. He handed the poster to Ning Qingyun next to him for a closer look, and asked: "I see the content on your poster, are you

Studying chemical physics?”

The so-called chemical physics is the 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 were both in the Department of Physics of Aurora University. My postgraduate major is 'Chemical Physics', which mainly studies liquid structure, equilibrium state and transport theory.

Statistical mechanics, constitutive thermodynamic properties of various states of matter, etc. The 'electrochemical desalination' in the poster was a subdivision of my research during my Ph.D., and the research results on the poster were all completed by me."

[A novel app that has been running stably for many years, comparable to the old version of the source-changing app, huanyuanapp, that is used by all chasing bugs.]

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

"A high-efficiency, low-energy consumption and fully automatic new seawater dewatering technical solution" although the title says a "technical solution", it is actually a large and complex technical system, including photovoltaic wind and tidal power generation, energy storage, seawater

The new seawater dewatering technology system that integrates dewatering and dewatering requires a large investment in initial infrastructure and equipment. After that, it can basically achieve self-sufficiency in energy. It does not require additional energy supply. At most, it requires equipment.

The cost of replacing consumables and decontaminating seawater is very low.

In the seawater denaturation section alone, several brand-new denaturation methods are mentioned. According to different environmental conditions, one or more combinations can be selected for seawater denaturation.

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

Qin Ke wanted to test 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, inlet water concentration, electrode and

System resistance, electrode porosity and other parameters, what are the desalination capacity, charging efficiency and thermodynamic efficiency of the membrane CDI you mentioned in the poster, and how were 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 takes action, he will know if there is any." When Qin Key asked a question, it was an extremely professional desalination performance indicator. This was at least a detail that only a doctoral student in the relevant major would understand. How could Luo Shouqing not be surprised?

You must know that according to rumors, Qin Ke is good at fluid mechanics and quantum mechanics in physics.

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

Luo Shouqing was amazed and did not dare to be negligent in the slightest. He vaguely knew that he was facing an unprecedented opportunity, and immediately answered seriously: "The kinetics of desalination are controlled by the electrochemical process and the diffusion rate from the bulk electrolyte to the solid-liquid interface.

, where charge efficiency is calculated as the ratio of salt removed to charge put in..."

He took out a paper and pen and wrote down a line of formula: "Fns/Qcharge", and then explained: "F is Faraday's constant (26.801mol^(-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 down the calculation formulas for more than a dozen indicators such as Coulomb efficiency, desalination completion speed, flow efficiency, energy indicators, etc., nearly half of which Qin Ke did not mention.

Qin Ke asked several more detailed questions such as "electrochemical desalting mechanism", "the relationship between the desalting ability of carbon electrodes and the charge storage capacity of carbon materials", "the principle of ion removal through charge compensation of redox active electrolytes", etc.

, Luo Shouqing was able to answer in seconds, showing his extremely outstanding talent and ability in the direction of electrochemical desalination.

Qin Ke asked unexpectedly: "Your skills are very good. You also studied for your Ph.D. at Aurora University? Why can't you even apply for the poster exhibition booth of the Physics Society? No tutor to help recommend?"

Generally speaking, poster exhibition booths are prepared for doctoral students who are about to graduate, postdocs who are being trained in postdoctoral stations, and doctoral students who have graduated less than two years ago, and young lecturers. The requirements are not very strict, and there are supervisors who can help recommend and research

If the students are qualified and qualified, the Physics Society will most likely pass the review and be given a poster display booth, which can be regarded as giving newcomers a chance to stand out.

Qin Ke made a comprehensive judgment based on the information he had just read and asked questions. Luo Shouqing's professional level was quite good, with a postdoctoral level, but it was a bit strange to see him doing so poorly and not even being able to apply for a display booth.

Hearing Qin Ke's question, Luo Shouqing's expression darkened, with a look of anger 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 and were afraid that something might happen to Qin Kening Qingyun and they would be dissatisfied, so they hurried over to deal with it.

"Nothing's wrong. I happened to meet Dr. Luo. Thinking that he is a physics colleague, I asked him a few questions." Qin Ke shook hands with the two officers, then stood up and said to Luo Shouqing:

"If you have any unspeakable secrets, forget it. I see from your poster that your level is high. Don't give up on the path of physics. If there are any obstacles that you can't overcome, just contact me."

Qin Ke touched his pocket and happened to have 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 the Department of Mathematics and Physics of Qingmu University" and his email 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.

This chapter is not over yet, please click on the next page to continue reading! Luo Shouqing was stunned for a long time. He had been getting so many looks in the eyes these days. This was the first time someone recognized him like this and showed kindness to him. He just felt his nose was sore.

Heat surged in his chest. He did not accept the business card, but took a deep breath and said risk-free: "Professor Qin, I did not study for my Ph.D. at Aurora University, but at Southern University of Science and Technology, but I dropped out before finishing it...

"

He told his past stories 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 "electrochemical desalination" direction that he was most interested in. During his hesitation, he happened to meet his supervisor at an academic conference.

Professor Qi Chengfu from Southern University of Science and Technology was famous for his expertise in electrochemical sewage treatment, so he was interested in applying for Professor Qi's doctoral degree.

At that time, his supervisor was not very supportive, and politely said that Professor Qi was more "strict" and "demanding". However, Luo Shouqing was full of confidence and believed that his level was high enough, so he still insisted on applying for Professor Qi Chengfu's doctoral degree.
