Mastering future technology, making a profit of 80 billion at the beginning

Chapter 11 Acting
Led by Lin Feng, the two walked into the laboratory.

This was originally an office, but after Lin Feng's management, it has been completely renovated.

Wang Xiaoxiong looked left and right, just like Granny Liu entering the Grand View Garden, and exclaimed from time to time.

"Wow! It's a beaker."

"What is this? A thermometer? Why is it so big and thick?"

Lin Feng did not stop him from behind. Instead, he looked at Wang Xiaoxiong's ignorant look with a smile on his face.

In fact, the purpose of building this laboratory is not just for the two of them to be admitted to Tianjin University.

If we want to turn those new materials, new medicines and new reagents in our minds into real things, we need to conduct experiments.

Now that Lin Feng is rich and his father's company has space, he immediately started to build his own laboratory.

Of course, it is just beginning to take shape now, and there are still many advanced instruments and equipment that need to be purchased from abroad.

But there is no need to rush now, as the current materials are more than enough to carry out experiments on preparing graphene.

"Okay, let's start the experiment."

Lin Feng grabbed the curious baby and began to instruct, "Next, we are going to conduct a graphene preparation experiment."

Seeing Lin Feng talking about serious matters, Wang Xiaoxiong quickly put down the unknown device in his hand and turned his head to listen carefully.

"I told you before that graphene is actually a single layer of graphite. Generally speaking, it does not exist alone."

As he spoke, Lin Feng walked to the experimental table, where several pieces of high-quality graphite he had purchased were placed.

"Even now, scientists have different attitudes towards graphene. Some believe it can be extracted, while others believe it is impossible for graphene to exist alone."

"For a long time, there has been a lot of debate because no one has been able to extract graphene from graphite."

"And what we are doing today is to prepare graphene using vapor deposition."

After Lin Feng finished speaking, Wang Xiaoxiong looked confused and asked, "What is vapor deposition?"

"Chemical vapor deposition (CVD) is a technology that deposits thin films or layered materials on a substrate using chemical gases. Do you understand? Do you have any questions?"

Wang Xiaoxiong was a little crazy. He understood every word, but when they were put together, his brain was completely unable to comprehend them.

What a shame!

In order to save face in front of his good brother, Wang Xiaoxiong pretended to be enlightened, "So that's how it is. I understand."

Lin Feng did not expose him, but just looked at Wang Xiaoxiong with a half-smile, until his face turned red, then he spoke quietly,
"Then let's get started."

After saying that, Lin Feng took action.

While operating, he began to explain to Wang Xiaoxiong,
"The most important thing about chemical vapor deposition is the choice of substrate. If the substrate is chosen correctly, the experiment is halfway to success. After consulting a lot of literature, I think copper foil is a very good material. Daxiong, put the copper foil in the high-temperature tube furnace."

Wang Xiaoxiong nodded, but was dumbfounded after picking up the copper foil because he didn't know what a high-temperature tube furnace was.

"It's the one next to you. Just pull it out and put it in."

Following Lin Feng's instructions, Wang Xiaoxiong carefully placed the copper foil into the high-temperature tube furnace. "What next?"

"Ignite! Monitor the temperature. Our target is 800°C. Tell me when it's reached."

Wang Xiaoxiong nodded, listened carefully to the thermometer on the stove, and began to get nervous.

“100, 200, 500, 800. Here we are!”

"Okay, watch carefully while I start introducing hydrogen."

"hydrogen?"

Hearing this name, Wang Xiaoxiong shuddered. He subconsciously took a step back and asked tremblingly,
"Mad man, will this thing explode?"

Lin Feng laughed secretly and said in an extremely sure tone, "Of course not. You just acknowledged me as your godfather. How could I harm you?"

"roll!"

The joke dispelled his fear, and Wang Xiaoxiong stared at the reactor again.

Lin Feng was not joking. What he injected was not hydrogen at all, but ordinary air.

Open the air valve and the gas will slowly flow into the furnace.

Compared to Wang Xiaoxiong's nervousness, Raymond Lam was full of confidence.
"Nobita, just watch carefully, the next moment is going to be the moment to witness a miracle!" Then, Lin Feng moved in one smooth motion.

Shut off the air valve, end the reaction, cool, and then open the furnace.

"Nobita, look carefully, the black film on the copper foil is graphene!"

Lin Feng confidently directed Wang Xiaoxiong to observe without even looking at him.

However, Wang Xiaoxiong did not sound surprised or happy. Instead, he said hesitantly,

"Mad man, there's nothing on the copper foil."

Lin Feng "of course" didn't believe it, he said, "How is it possible, Daxiong, take a good look."

"Not really."

Lin Feng snatched it away and looked at it carefully from head to toe.

Finally, he staggered back in dismay, a look of disbelief on his face.

"Impossible, absolutely impossible!"

"There is absolutely no way my calculations could be wrong."

Looking at his appearance, Wang Xiaoxiong felt both distressed and worried.

"Crazy, maybe I didn't put it in properly, do you want to try again?"

Hearing Wang Xiaoxiong's words, Lin Feng nodded repeatedly as if he had grasped a life-saving straw. "Yes, yes, yes, let's try it again."

After saying that, the two returned to their original positions and repeated the steps just now.

This time, Wang Xiaoxiong was particularly serious, because what he held in his hands was not only copper foil, but also his brothers' hope.

Place it carefully and adjust the temperature carefully.

But as expected, the experiment failed again because Lin Feng did not inject hydrogen but ordinary air.

With Wang Xiaoxiong's comfort, Lin Feng gradually calmed down.

He worked out every detail from scratch, from temperature control to gas flow.

If you write wrong data, just use tape to fix it.

Soon, Lin Feng corrected the data.

He waved the calculation manuscript excitedly, "It's 1000℃, not 800!"

After saying that, the two of them plunged back into the intense experiment.

Under Lin Feng's control, the results were the same as always.

The copper foil is smooth and there is no graphene on it.

"Madman, don't be discouraged..."

Wang Xiaoxiong was just about to say something to comfort Lin Feng, but he saw him sitting back on the bench and starting the deduction again.

He continued to use tape to stick down the wrong data while mumbling,
"Damn, chemical methods are not reliable at all. It would be great if we could use physical methods to directly cut graphene out of graphite."

Wang Xiaoxiong, who was walking behind Lin Feng, just happened to hear these words.

Looking at Lin Feng's calculation paper which was destroyed by the tape and only a thin layer was left, suddenly a flash of lightning flashed through his mind.

He grabbed Lin Feng's shoulders and said excitedly,
"Madman, you said graphite is made up of layers of graphene stacked one after another?"

Lin Feng didn't understand why he was so excited. He was busy calculating and answered without turning his head, "Yes."

"So does that mean that if we peel off the graphite layer by layer, we can get graphene?"

Finally figured it out?

Lin Feng, with his back to Wang Xiaoxiong, showed a meaningful smile, but when he turned around, he looked bewildered.
"Yes, what's wrong."

Wang Xiaoxiong was excited as he took the battered piece of calculation paper from Lin Feng's hand.

Pointing at the place that was almost transparent due to Lin Feng's repeated modification of the data,
"look!"
