Material Empire

The large lecture hall of the Ann River School of Materials can accommodate 300 people to listen to reports at the same time. It is rarely used in normal times, but it is an exception to open today. Scientists and engineers from all over the world packed the entire lecture hall. Some of them couldn't find a place to stand, so they could only stay in the corridor, looking into the lecture hall on tiptoe. Stepping into the lecture hall, you can only hear English with various accents, including a pure London accent, an American accent with a rough Virginia style, and a Japanese English with a taste of salted fish in Tokyo Bay. To the South Asian pronunciation of a few sentences of "Ingrixu".

This is the world's first symposium on graphene technology. According to the organizer of the symposium, Anhe Institute of Materials Science and Technology, after the symposium, there will be discussions on cooperative development of graphene products. After being notified of the meeting, hundreds of universities and companies from all continents around the world have sent their most capable personnel 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 produce finished graphene 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 blushing face, mustered up his courage and said in a clear voice to a room full of foreigners: "Ladies_and_gentlemen, Welcome_to_Hongzhe..."

Today's Wang Xiaochen is no longer the young and timid country worker when Qin Hai first met her. Since she was appointed as the assistant to the dean of the School of Materials a few years ago, the world she comes into contact with is getting bigger and bigger, and she deals with people every day. The top domestic scholars have gradually cultivated a calm and confident temperament. In order to be able to fully communicate with scholars and understand their needs, Wang Xiaochen always finds ways to spare time to attend lectures with students, and sometimes to participate in internal seminars in various laboratories. Now he is considered a half-hearted material scientist. buffs too.

With the increasing international influence of the School of Materials Science and Technology and the increasing foreign exchanges, Wang Xiaochen, with the encouragement of her husband Song Hongxuan, began to learn English by herself, and now has no major problems in dealing with general foreign affairs. However, it is the first time for her to host such an international academic conference.

"People from so many countries have come here, 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 at Qingfeng Factory, desperately waving his hands to evade with.

"How could you mess up the pot?" Qin Hai smiled, "In the School of Materials, you also presided over a staff meeting with thousands of people. This time, it was only a few hundred people. What are you afraid of?"

"However, all the scholars who come here are famous international scholars. If I say something wrong, people will laugh at me." Wang Xiaochen said.

"Who dares?" Qin Hai stared and said, "They don't even think about it. How many people are crying and wanting to cooperate with the School of Materials, but we haven't agreed. Being able to let these people come to the meeting is already enough to give them face. , Who dares to laugh at you, you immediately ask the security to throw them out, put their names on the blacklist of the School of Materials, and never cooperate."

"Boss Qin, you're kidding me again!" Wang Xiaochen scolded. Of course she knew that Qin Hai was joking, but the joke was not unfounded. She, the dean's assistant, couldn't make it through, she was definitely out of her mind.

"Can Dean Long be the host, or Professor Li can be the host." Wang Xiaochen is still making the last effort to get Long Changsheng or Li Linguang to replace him.

Qin Hai shook his head resolutely, and said: "No, they are all old, and things like this will definitely fall on your shoulders in the future. This is a chance to practice, and you must play."

"Then...you want to help me off stage, okay?" Wang Xiaochen knew that he couldn't beat Qin Hai, so he had to settle for the next best thing, and begged Qin Hai to escort her. Over the years, the person Wang Xiaochen admired the most was Qin Hai. If Qin Hai was sitting in the audience, her courage would increase by three points.

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

Qin Hai would naturally attend such an important meeting in person. According to his original plan, he should be the one who presided over the meeting instead of Wang Xiaochen. The suggestion to let Wang Xiaochen preside over the meeting was put forward by several old people from the School of Materials Science and Technology, namely Fu Wenbin, Long Changsheng and Li Linguang. It was transferred to Wang Xiaochen, so Wang Xiaochen was urged to be the host of the meeting.

After accepting this task, Wang Xiaochen started to get busy. She first had to learn from Nie Sen about the specific situation of the meeting, to determine what she should say and how to 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 make mistakes, she rehearsed many times, and was finally identified by her English teacher as being able to work as an announcer for the BBC.

Facts have proved that it is indeed a good choice to let Wang Xiaochen be the host. Among the scholars who came to the conference this time, most of them were men. Even if there were some women, most of them were middle-aged and young ladies, and they were somewhat dull. Wang Xiaochen was just in her early 30s, and she had the charm of a young woman. Once she stood on the podium, she immediately attracted everyone's attention, which also added a bit of bright color to such a serious meeting.

"I'm very happy to meet friends from all over the world here, and welcome everyone to participate in the graphene project cooperation of Anhe School of Materials Science and Technology. Next, let's invite Professor Nie Sen, the discoverer of graphene, to give you a special introduction." Wang Xiaochen Steady mind, finished the opening remarks in a peaceful tone, and handed the stage to Nie Sen. When she stepped off the podium and sat next to Qin Hai, she felt that her back was soaked in sweat.

"It's a good speech, and it looks like everyone." Qin Hai gave Wang Xiaochen a thumbs up and praised in a low voice.

"I'm so nervous..." Wang Xiaochen said with a smile on her face. In fact, she was quite satisfied with her performance just now, and her self-confidence tended to burst.

"Just practice a few more times." Qin Hai said, "Next time we go to New York to develop a press conference, we will let you host it."

"That will have to wait for me to practice English again." Wang Xiaochen replied seriously.

The scholars in the room didn't notice the exchange between Wang Xiaochen and Qin Hai. Their attention was all attracted by Nie Sen on the podium.

After publishing a short reporting paper on Science, Nie Sen published a 40-page long paper on the "Nanomaterials" magazine, which systematically introduced various properties of graphene. All the scholars who came to the conference today have read through this article and conducted in-depth research on some of its contents. Even so, Nie Sen's report at this time still brought countless shocks to them.

"Using the first principles, we used aluminum, cobalt, nickel and other metal elements to infiltrate the surface of graphene. The following pictures are the energy band structure diagrams of graphene and various metal surface interface structures... "

While Nie Sen was talking, he printed a huge schematic diagram and electron microscope photos on the projection screen. The scholars sitting below frantically took notes with their notebooks, and some held up expensive cameras, clicking and snapping these precious pictures.

Nie Sen's narration seems to be very detailed, but in fact there are still some trade-offs. The Anhe School of Materials has set up several research groups, and has chosen a few of the most valuable and promising directions to tackle key problems. Nie Sen has consciously avoided the relevant content in these directions. The scholars present could not hear this kind of evasion. After all, a new material has just been discovered, and it is normal that its performance has not received attention. Who would have expected Nie Sen to be so dark-hearted?

Nie Sen spoke for a full hour and a half, and then it was time for the audience to ask questions as usual. Everyone rushed to raise their hands, so that Nie Sen didn't know who to let speak first. At this time, Wang Xiaochen didn't know what to do, so Qin Hai had no choice but to go on stage to make a rescue.

"Everyone, I can see that everyone is very interested in Professor Nie's speech, and there are many valuable ideas that they hope to communicate with Professor Nie. However, I took a quick look, and there are seventy to eighty friends who raised their hands and asked to speak. Hey, if everyone says two minutes, we will delay lunch. I think, can we do this, everyone saves their own questions first, and we will arrange four special sessions in the next three days, so that everyone can fully understand discuss.

Some of your questions may only need Professor Nie's assistant to answer, so we don't have to bother Professor Nie to answer in person. If it is really necessary to communicate with Professor Nie himself, we can coordinate the time. What do you think? "Qin Hai smiled and made arrangements for everyone.

"Very well, I think this is more appropriate!" Someone responded loudly. In fact, people who understand a little bit can also see that now is not the time to communicate at all, and some people are really talking too much.

"In order to let everyone have some basic understanding of the characteristics of graphene, we have prepared 100 graphene samples, each containing one gram of graphene, and each institution is limited to one. We have also vacated 20 laboratories for convenience. We are doing some basic experiments here, but for the sake of fairness, we need to charge you a little laboratory occupancy fee. If you need friends in this regard, you can register with Ms. Wang!" Qin Hai said, pointing his fingertips Wang Xiaochen sitting under the stage.

Before she finished speaking, Wang Xiaochen felt a buzzing in her ears, and countless people suddenly appeared in front of her, shouting loudly:

"I want!"

"We need a laboratory!"

"We're willing to pay double the price!"
