The large lecture hall of Anhe Institute of Materials can accommodate 300 people at the same time, which is rarely used in normal times, but today it is open on an exceptional basis. Scientists and engineers from all over the world crowded the lecture hall, and some people couldn't find a place to stand, so they could only stay in the hallway, tiptoeing into the lecture hall. When you step into the lecture hall, you can only hear English with various accents, including pure London accent, American accents with a rugged Virginia style, Japanese English with the taste of salted fish in Tokyo Bay, and occasionally a few South Asian pronunciations of "Ingritsu".

This is the world's first graphene technology seminar, and according to the organizer of the conference, Anhe Institute of Materials, there will be negotiations on the cooperative development of graphene products after the conference. After receiving the notice of the meeting, hundreds of universities and enterprises on all continents around the world sent their most capable people to rush to Anhe Hongze, a little-known second-tier city in China. There is no other reason, just because so far, there is only one company that can come up with graphene finished products, and there is no semicolon.

When the time for the meeting came, Wang Xiaochen, who was pushed out by Qin Hai to preside over the meeting, walked up to the podium with a red face, plucked up the courage to say in a clear voice to a room of foreigners: "Ladies_and_gentlemen, Welcome_to_Hongzhe......"

Today's Wang Xiaochen is no longer the young and timid country female worker when Qin Hai first met her, since she was appointed as the assistant dean of the School of Materials a few years ago, she has been exposed to the world more and more, and she deals with top scholars in China every day, and has gradually cultivated a calm and confident temperament. In order to be able to fully communicate with the scholars and understand their needs, Wang Xiaochen always finds time to attend lectures with students, and sometimes attends internal seminars in various practical rooms. Now he is also a half-baked water material science enthusiast.

With the increasing international influence of the School of Materials and the increasing number of foreign exchanges, Wang Xiaochen began to learn English by herself with the encouragement of her husband Song Hongxuan, and now there is no big problem in dealing with general foreign affairs. However, to preside over such an international academic conference. It was a first for her.

"People from so many countries have come, what if I mess up the pot?" When Qin Hai handed over this task to her, Wang Xiaochen suddenly returned to the way he was when he was in Qingfeng Factory, desperately waving his hands to push back.

"How did you mess up the pot?" Qin Hai said with a smile, "In the School of Materials, you have also presided over the staff meeting of thousands of people, but this time it is only a few hundred people, what are you afraid of?" ”

"However, all of them are international scholars. If I say something wrong, people will laugh at me. Wang Xiaochen said.

"Who dare?" Qin Hai glared and said, "They don't want to think about it, how many people are crying and shouting now that they want to cooperate with the School of Materials, we haven't agreed, being able to let these people come to the meeting is enough to give them face, who of them dares to laugh at you." You immediately have the security guards blast them out and put their names on the blacklist of the Materials Academy. Never cooperate. ”

"Mr. Qin, you're teasing me again!" Wang Xiaochen said angrily, of course she knew that what Qin Hai said was a joke, but this joke was not unfounded, this meeting was indeed the home of the School of Materials, and she dared to have trouble with her, the assistant to the dean, at this meeting. It's definitely the brain.

"Can you let Dean Long preside, or let Professor Li preside." Wang Xiaochen was still making his last effort, wanting Long Changsheng or Li Linguang to replace him.

Qin Hai shook his head resolutely and said, "No." They are all old, and in the future, such things will inevitably fall on your shoulders, this is an opportunity to practice, you have to play. ”

"That'...... You're going to help me offstage, okay? Wang Xiaochen knew that she couldn't beat Qin Hai, so she could only retreat and beg Qin Hai to escort her. For so many years, Wang Xiaochen's most convincing person is Qin Hai, if Qin Hai is sitting in the audience, her courage can increase by three points.

"No problem, I'll be there the whole time." Qin Hai readily agreed.

For such an important meeting, Qin Hai would naturally be present in person. According to his original plan, it should be himself and not Wang Xiaochen who presided over the meeting. The construction of letting Wang Xiaochen preside over the meeting was proposed by several old people from the School of Materials, that is, Fu Wenbin, Long Changsheng and Li Linguang, who watched Wang Xiaochen gradually grow up, and also intended to transfer the burden of the School of Materials to Wang Xiaochen, so they strongly advocated letting Wang Xiaochen be the host of the meeting.

After accepting this task, Wang Xiaochen began to get busy. She first asked Nie Sen about the specifics of the meeting, and determined what she should say and how she should say it. Then, she wrote a detailed speech, first asked Song Hongxuan to help her polish the content, and then asked the English teacher in the college to help translate it into English. In order to ensure that her pronunciation would not go wrong, she rehearsed many times, and finally was recognized by her English teacher as being able to go to the BBC as an announcer, which can be regarded as a steady.

Facts have proved that letting Wang Xiaochen be the host is indeed a good choice. Among the scholars who came to the conference this time, most of them were men, and even if there were some women, most of them were half-aged, and they were somewhat wooden. Wang Xiaochen was just in his early 30s, with the charm of a young woman, and when he stood on the podium, he immediately attracted everyone's attention, which also made such a strict meeting suddenly add a bit of bright color.

"I am very pleased to be able to meet colleagues and friends from all over the world here, and I also welcome everyone to participate in the cooperation of the graphene project of Anhe Institute of Materials. Wang Xiaochen stabilized his mind, finished the opening remarks in a calm tone, and handed over the stage to Nie Sen. When she stepped off the podium and sat down beside Qin Hai, she felt that her back was already soaked with sweat.

"It's a good speech, and it's very personable." Qin Hai cocked a thumbs up to Wang Xiaochen and praised in a low voice.

"I'm nervous...... Wang Xiaochen said with a smile on her face, in fact, she was quite satisfied with what she had just done, and her self-confidence tended to burst.

"Just practice a few more times." Qin Hai said, "Next time we go to New York for a research conference, we will let you preside over it." ”

"I'll have to wait until I practice my English again." Wang Xiaochen replied seriously.

A room full of scholars didn't notice the communication between Wang Xiaochen and Qin Hai, and their attention was all attracted by Nie Sen on the podium.

A short reportage paper in Science was followed by a 40-page paper in the journal Nanomaterials, which systematically described various aspects of graphene's properties. All the scholars who came to the meeting today have read through this article and have conducted in-depth research on some of the contents of the article, even so, Nie Sen's report at this time still brought them countless shocks.

"We used first principles to surface infiltrate graphene with aluminum, cobalt, nickel and other metal elements, and the following pictures are the band structure diagrams of the interface structure between graphene and various metal surfaces......

As he spoke, Nie Sen typed out a huge schematic diagram and electron microscope photo on the projection screen. Scholars sitting below frantically took notes with notebooks, while others held up expensive cameras and snapped these precious images.

Nethane's account seems to be very detailed, but in fact, there are trade-offs. Anhe Institute of Materials has set up several research groups, and selected several of the most valuable and promising directions for breakthroughs. The scholars present couldn't hear this evasion, after all, a new material had just been discovered, and it was normal for which aspects of performance had not received attention, who would have expected that Nie Sen would be so black-bellied?

Nie Sen spoke for an hour and a half, and then, as usual, it was time for the audience to ask questions. Everyone scrambled to raise their hands, so that Nie Sen didn't know who to let speak first. At this time, Wang Xiaochen no longer knew what to do, and Qin Hai had no choice but to come to the stage in person to relieve the siege.

"Ladies and gentlemen, I can see that everyone is very interested in Professor Nie's speech, and there are many valuable ideas that I hope to exchange with Professor Nie. However, I took a cursory look and found that there were seventy or eighty friends who raised their hands to speak, and if each of them said two minutes, we would have to delay lunch. I wonder if we can do this, where everyone saves their own questions first, and we will arrange four special sessions in the next three days for everyone to fully discuss.

Some of your questions may only need Professor Nie's assistant to answer, so that we don't have to trouble Professor Nie to answer them himself. If you really need to communicate with Professor Nie himself, let's coordinate the time, what do you think? Qin Hai smiled and made arrangements for everyone.

"Very well, I think that's a good fit!" Someone responded loudly. In fact, people who understand a little bit of reasoning can also see that now is not the time to communicate at all, and some people are really talkative.

"In order to give you some basic understanding of the properties of graphene, we have prepared 100 graphene samples, each containing one gram of graphene, and each institution is limited to one. We have also freed up 20 real yàn rooms so that you can do some basic real yàn here, but for the sake of fairness, you need to charge a small fee for occupancy of real yàn rooms. Friends who need it in this regard can register with Ms. Wang! Qin Hai said, pointing at Wang Xiaochen, who was sitting in the audience.

Before the words fell, Wang Xiaochen felt a buzz in her ears, and countless people appeared in front of her at once, shouting loudly:

"I want it!"

"We need a real room!"

"We're willing to pay double!" (To be continued......)
