Since he agreed to Academician Ma's invitation, Liu Feng is not a person who breaks his promise, not to mention, there is very likely to be a navy in this.

After returning to Beijing University of Chemical Technology with Zhuo Tingting, he began to prepare for the next argument of electromagnetic catapult.

As for what to prepare......

On the last day of February, the sun was shining, and Liu Feng was in his office at Beijing University of Chemical Technology, where he conducted an aptitude test for his lovely students.

Well, the content of those 23 reference books has been reduced to 15 questions, with a time limit of two hours.

After handing over the test papers with the questions to several people, Liu Feng picked out the book from his desk and flipped through it carefully.

Da tick the minute by the minute.

As the mobile phone rang, Liu Feng snapped the book in his hand and looked at the few people who were still struggling to write on the paper.

"When the time comes, let me see how you learn this month. ”

Zhou Yue helped her black-framed glasses, and put down the pen in her hand with a headache.

"Professor, 2 hours is too tight, you see......"

got up and handed the test paper to Liu Feng's desk,

"I still have 5 questions to complete?"

I don't know if it's because the energy is used up, and the roll of 'stupid hair' on Fei Xiujin's head no longer stands up:

"Professor, if I had been given another five minutes, I would have been able to write the 12th question. ”

This guy only has 4 questions left to complete!

Zhou Yue glared at this guy with an angry face, and there were only two words in his heart - pretending to be forced!

Immediately afterwards, Zhuo Tingting and Du Hong's test papers were also handed in, and Liu Feng found that except for Fei Xiujin's guy, everyone else still had 5 questions that had not been completed.

He couldn't help but nod his head.

After going through everyone's answers briefly, I finally found that although Fei Xiujin is a little out of the mainstream, his talent in academics really has nothing to say, and it is even better than Miss Zhuo Tingting, who personally opened a small stove for a few days by Professor Liu.

It was really beyond his expectations.

"Actually, I didn't ask you to do every question, but in the end, you exceeded my expectations. ”

Liu Feng nodded and said as he corrected the test papers.

For him, the questions in the test papers are naturally very simple things, and he already has the answers when the questions are made; easily corrected everyone's test papers, and the final result did not have any accidents, Zhou Yue, Du Hong and Zhuo Tingting all answered 10 questions correctly, Fei Xiujin, well, this guy only answered 10 and a half questions correctly!

In question 11, there was a very low-level calculation error!

It's like a junior high school student who calculates that 1+1 equals 2 but answers it wrong, in Professor Liu's eyes, this is simply unforgivable!

Well, it's clearly a matter of attitude!

glared at Fei Xiujin and trembled.

It's just that, in general, the level of Zhou Yue, Du Hong and Zhuo Tingting is still in Liu Feng's expectations, and the only surprise is probably Fei Xiujin.

Putting the test paper aside, Liu Feng cleared his throat and glanced at the audience with a majestic gaze:

"First of all, congratulations on passing my test. ”

Hearing this, Du Hong, who was originally a little frustrated because he still had five questions to complete, raised his head and showed a surprised expression, and Xiao Fei, who was trembling, was even more surprised.

The others opened their mouths in surprise.

As if seeing through what they were surprised about, Liu Feng said in a relaxed tone:

"The passing mark I set is 8 questions, and you have all exceeded the standards I set for you, which shows that in this more than a month, you have not abandoned your studies, well, it is still commendable, but I must criticize someone!"

After that, he spread Fei Xiujin's volume on the table, and instantly turned into 'Extermination Master',

"Classmate Fei Xiujin, come and see for yourself, you can make such a low-level mistake, and the embankment of a thousand miles will be destroyed in the anthill!

Fei Xiujin could only step forward with his head drooped and respectfully accept the criticism.

"Therefore, in order to punish your carelessness, this time you will be rewarded - the opportunity to go on a business trip to Ningbo, you guy will not be there!"

What?

Reward?

Travelling to Ningbo for work?

"What, a business trip? to Ningbo?"

Fei Xiujin felt bad all over the place, he was deprived of the opportunity to travel at public expense!

"That's right, at the Naval University of Engineering, the aircraft carrier electromagnetic catapult developed by Academician Ma Mingwei has been successful, and after a circle from Ningbo, we will also go to Dalian to attend the Navy's aircraft carrier handover ceremony......

"Don't, boss!"

Fei Xiujin was about to kneel down for Liu Feng.

It's just a business trip, and deprivation is deprivation,

But electromagnetic catapults?

Aircraft carrier handover?

Don't you know that we are veteran military fans!

"I'm against it, Professor, take me with you! I promise that I won't make such a low-level mistake next time!"

Climbing up like a dog's legs, Fei Xiujin tugged at Liu Feng's sleeve and stared at him with blank eyes.

In addition to Fei Xiujin, even Zhou Yue and Du Hong also showed surprised expressions.

It's only been a little over a month, right?

And it's such a lofty opportunity - the handover of the aircraft carrier, it was a live broadcast on CCTV, and even the Grand Elder and others had to attend the grand ceremony, and they had the opportunity to participate?

It's awesome!

Sure enough, the more awesome the tutors, the more opportunities they have for these students, and the more they can follow the world!

In short, follow Professor Liu, and sure enough, it's right!

He stared at Professor Liu with adoration on his face.

If you want to say that the only one who behaves lightly here is the young lady Zhuo Tingting, after all, Liu Feng knows the news, and she naturally knows it;

What's more, even she went to the Great Hall of the People, and the Great Elder had been in contact with it, so what was this 'small' occasion?

"Objections are invalid!"

The corners of Liu Feng's mouth hooked up a smile, knowing that you are a senior military fan,

"It's still necessary for our school to leave someone to defend, if you accidentally get patronized by a thief, it won't be good, so ......"

"Professor, boss, Uncle Liu, you are my uncle, you can take me a little by the way!"

Fei Xiujin pitifully tugged at Liu Feng's sleeve, a handful of snot and tears, this posture, if Liu Feng didn't agree, he would have a feeling of jumping off the building directly.

Looking at Liu Feng with a smile on his face, Zhuo Tingting stood up:

"Professor, you can take him with you this time, I volunteered to stay. ”

In the past month or so, she and Liu Feng have been getting along almost day and night, and the two have been tired of being together all day long; although Liu Feng has opened a small stove for her, the young lady still feels that her homework has fallen behind; the future is long, she must take advantage of this time to precipitate, at least, she can't be left behind too much by the brothers and sisters, let alone embarrass Liu Feng!

Although the two had already discussed this ......, Liu Feng still felt a little reluctant.

It is the "newlywed Yan'er", when you and I are nong, this time we have to be separated for at least half a month, of course he is not happy.

But seeing Zhuo Tingting nodded, he could only sigh reluctantly,

"Okay, Zhou Yue, Du Hong, Fei Xiujin, the three of you are on a business trip with me, Zhuo Tingting, you stay and take care of the laboratory......"

"Hooray!"

Fei Xiujin's guy was already jumping up with excitement,

"Tingting, thank you, when you come back, senior brother will invite you to dinner!"

He shook his head helplessly.

"I'll take this opportunity to briefly talk about your subject. ”

After taking a sip of tea, Liu Feng stood up and turned on the projection in the office.

Zhuo Tingting also took the initiative to move a few stools and arranged them.

Everyone sat down in front of the projection and waited for the boss to speak.

"More than a month ago, I arranged for you to study materials for this year and a half, and this time, I have prepared your subject as well. ”

"Speaking of which, we are majoring in materials science, but my requirements for you are naturally not just to be proficient in materials chemistry. Of course, this is a later story, and the topic I am going to give you now is indeed related to materials science. ”

Zhou Yue, Du Hong and the others nodded one after another.

Judging from the learning tasks assigned to them by Liu Feng, they have already thought of this, and this is also what they are happy to see.

As a university bully, and there is Liu Feng, a world-famous all-rounder and master, if they can only be proficient in one discipline of materials chemistry, it is really a waste of their talent and resources; of course, it is not impossible to be proficient in one subject, but if you can learn a little more knowledge, why not?

Fei Xiujin, who has always been funny and non-mainstream, also looked serious, although he loves to play, he is never ambiguous in his studies.

After a pause, Liu Feng continued to preach.

"Since it's about materials, your task is naturally to develop a new practical material. I have listed here the R&D routes of 13 types of new materials, involving information materials, biological materials, automotive materials, nanomaterials, superconducting materials, rare earth materials, new steel materials, new non-ferrous metal alloy materials, new building materials, new chemical materials, energy materials, ecological environment materials, and new military materials. ”

"Boss, can the four of us choose the same classified material route for research?"

Du Hong raised his hand a little nervously and asked.

After all, they all belong to the category of chemistry now, and most of the 13 material research routes belong to the category of metals and physics, and the requirements for the accumulation of knowledge in chemistry are relatively low.

As if seeing through his lack of confidence, Liu Feng said in a relaxed tone:

"Of course, you can, but I still recommend that you have the courage to try new areas, which will be very beneficial for your future development. ”

In today's development of science and technology, there are few cutting-edge research that simply involves only one kind of subject knowledge, and often physics, chemistry and biology intersect with each other, so Liu Feng hopes that his disciples can adapt to this trend as soon as possible.

Of course, he naturally does not force them to choose what topic, everyone has their own ambitions, does what they can, and follows their own interests, which is also a proper direction of development.

Several people looked at the screen projection and hesitated.

Seeing this, Liu Feng smiled and continued:

"Since you are hesitant, then I will give you an in-depth analysis of what these research routes are. First of all, there are informational materials. ”

After speaking, I tapped the keyboard, and the PPT went to the next page.

As the name suggests, the so-called information materials are electronic information materials, and their products support the entire modern high-tech industries such as modern communications, computers, information networks, micromechanical intelligent systems, industrial automation and home appliances. ”

"Its development scale and technical level have an important strategic position in the national economy, and it is the most fierce material field of scientific and technological innovation and international competition!"

"Electronic information materials can be divided into the following categories:

Integrated circuits and semiconductor materials: silicon materials are the main body, and new compound semiconductor materials and a new generation of high-temperature semiconductor materials are also important components, of course, including high-purity chemical reagents and special electronic gases;

Optoelectronic materials: including laser materials, infrared detector materials, liquid crystal display materials, high-brightness light-emitting diode materials, optical fiber materials and other fields;

New electronic component materials: including magnetic materials, electronic ceramic materials, piezoelectric transistor materials, information sensing materials and high-performance packaging materials.

Among them, microelectronic materials are still the most basic information materials in the next 10~15 years, and optoelectronic materials will become the fastest growing and most promising information materials, the current research hotspots and technical frontiers include flexible transistors, photonic crystals, SiC, GaN, ZnSe and other wide bandgap semiconductor materials as the representative of the third generation of semiconductor materials, organic display materials and various nanoelectronic materials. ”

At this point, Liu Feng paused for a moment, smiled and continued.

"To put it bluntly, as long as human beings are inseparable from informatization for a day, information materials will not become obsolete. ”

Of course – it's the least proficient subject he's at the moment!

After listening to Liu Feng's introduction, the three brothers and sisters looked at Liu Feng with blank eyes, and they felt like they were trying to leap and try, after all, the boss looked so powerful!

It's just that there are still 12 categories waiting for them to choose, and there is no hurry.

Seeing this, Liu Feng was a little disappointed.

This thing's heart naturally hopes that the apprentices will develop in this direction, after all, learn from each other's strengths, and when he has any problems in this regard in the future, the apprentices may be able to bring him a lot of surprises!

Shaking his head, he continued with the introduction of other material categories.

Next, there is the introduction of energy materials. ”

Fei Xiujin raised his hand and skinned it: "Boss, shouldn't it be biological materials?"

Liu Feng: "......"

Can he say that this is the material he is least good at in the second category?

When he was in Ningbo, he had in-depth research on superconductivity, rare earth and other materials, and when he was researching new drugs in Jiangzhou, he also used to hunt rabbits with grass and study the knowledge of biomaterials, coupled with his inherent ability to control particles in the microscopic world, especially the research on nanomaterials and other directions.

Only the two large pieces of information materials and energy materials have never been touched, that is, not long ago, in order to assign tasks to the apprentices, I frantically swiped a few reference books on these aspects.

Of course, Professor Liu will never mislead people's children, well, absolutely not!

"Classmate Fei Xiujin, I know you have obsessive-compulsive disorder, but," Tutor Liu patted the table, "Boss, I also have ......"

What meme?

I don't understand!

Fei Xiujin and Du Hong glanced at each other and looked at each other.

Zhou Yue bit the tip of the pen, looking like a good baby, and listened attentively.

Only Miss Zhuo Tingting covered her mouth with her hands and snickered.

Only she knew what Liu Feng meant.

After all

When I made this PPT yesterday, I asked the same question......

"Ahem~", glaring at the young lady, Liu Feng cleared his throat and pretended to be stern, "Zhuo Tingting, this is in class, be serious!"

"Yes, boss!"

In an instant, the young lady sat up, but she really didn't realize that her Professor Liu was really cute!

Hee-hee!
