After finishing the Mars Science Exchange Summit in the morning, Chen Mengchuan went back to his room a little tired to rest for a while, washed his face, and relaxed himself. ◢ With ◢ Dream ◢ Small ◢ The content of these science summits is very large, and the time is very long, and everyone communicates some very quintessential things, and it is not easy to digest these things.

After shaking off the water in his hand, Chen Mengchuan squinted his eyes, not knowing when, he was a little sour.

When he walked out of the room and went to the centralized canteen area, he received a voice message from the main control room, which made him stunned, and then smiled, put it aside for the time being, he planned to eat first.

The canteens of the Mars base are all centralized, walking in many areas, just after the scientific exchange summit, there are crowds of people eating, drinking and communicating.

Chen Mengchuan took a piece of food, the food is bento-style, the amount is not large, most of the people according to the weight range recommendations, to pick up the meal, there are many food categories, not too monotonous, and there are a large number of drinks and vegetable and fruit salad can be picked up at any time.

After taking the number of meals, Chen Mengchuan found Toni and Chen Xiaoyun at the small round table where several people often ate, walked over with the dinner plate, and communicated with the two while eating.

After a while, Xu Shuwei came to the canteen area in a hurry and found Chen Mengchuan and the others.

"Whew...... You're still in the mood to eat! Yumekawa! ......," Xu Shuwei said with a pant.

"People are iron and rice is steel, and if you don't eat a meal, you are hungry and panicked, so you come to eat. It's as simple as that, and it's not a big deal. Chen Mengchuan said with a smile.

"Okay, okay, you're awesome, huh, I've eaten a little bit in the morning until now, and when you say this, I also feel hungry and panicked, no, I'll go get a lunch first." After Xu Shuwei finished speaking, he walked towards the self-service pick-up gate.

"Well, I'm interested in what you're up to." Toni looked at Chen Mengchuan.

As he spoke, Chen Xiaoyun also looked at Chen Mengchuan, and there was some curiosity in his calm eyes.

Chen Mengchuan smiled and didn't answer his question, but just raised his head and raised his chin in the direction of Xu Shuwei, meaning that he would say it when Xu Shuwei came.

Toni pushed his glasses and looked at Xu Shuwei.

Xu Shuwei quickly prepared food and walked over, he took a large tray with a slightly larger bento in it, as well as a whole fried chicken, a large glass of soda, and a basin full of vegetable and fruit salad.

"Aren't you trying to lose weight? Can you eat so much? I won't kill you. Chen Mengchuan rolled his eyes.

"Haha, people are iron and steel, and if you don't eat a meal, you're hungry, and you're hungry, so you have to eat more, didn't you say it yourself. Besides, look at my size, if I don't eat so much, I won't starve to death? What's more, are there so many of these things? It's just a matter of eating three points full. Xu Shuwei sat down in front of the three of them and got down. Placed the large plate on the table.

Seeing Xu Shuwei grunt and drink a large glass of soda first, Toni opened his mouth and asked him, "Say, what's going on." ”

"Haha, Toni, guess what." Xu Shuwei saw that Chen Mengchuan didn't tell the two of them, so he played a trick.

"I'm too lazy to guess, let's say, did you find something good by exploring the multi-armed crab?" Toni asked.

Xu Shuwei smiled very brightly, and his chubby body trembled a little.

"We found diamonds in a large crater with a diameter of 20 kilometers in the northern region of Mars! Lots of diamonds! No, it's a lot of diamonds! Now the guys at the Department of Geological Research are going crazy right now, and they have estimated that the crater's diamond reserves are unusually staggering. Contains abundant diamond resources! These diamonds are all impact drills, which are supposed to be produced when meteorites hit the graphite deposits of the Martian crust, I don't know how long they have existed, and the reserves are very amazing, and they are everywhere when they are excavated, and the volume is very ...... Very exaggerated! ”

"Now the exploration type dobby crab has begun to explore, and many large diamond bodies have been found, and a single diamond of tens or even hundreds of kilograms has been found."

However, several experts say that these large diamonds are all crystalline blue sdale stones, which are actually allotropic forms of carbon with hexagonal lattices. The average hardness of these diamonds is more than 50 percent higher than that of ordinary diamonds, and the individual is larger, making them more suitable for industrial and scientific applications. But if you really sell it, you will definitely make a fortune. Xu Shuwei smiled.

Toni glanced at him, but didn't speak, his expression not fluctuating at all.

"Is it useful? I mean, this diamond mine, do you mean that after it is dug up, it will be sold in jewelry stores on Earth? Chen Mengchuan was a little speechless.

"Ahem, of course...... No, you can't sell it. Xu Shuwei was suddenly a little deflated, and the excitement of discovering the diamond mine was as if he was deflated for a moment.

"Are we short of money? There is no shortage, besides, how slow do you have to sell so many diamonds to the earth? Taking a step back, even if they throw these diamonds to the seven diamond giants, it is estimated that the other party will not accept them, and it is estimated that they have too many diamonds in their hands to sell. Not even an industrial value. 60 years ago, General Motors in the United States had mastered the technology of obtaining synthetic diamonds through high temperature and high pressure, and the industrial value of natural diamonds has completely disappeared, and the main use of natural diamonds is now limited to jewelry and ornamentation. Chen Mengchuan said slowly.

"If a large metal mine is discovered, it would be worth rejoicing." Toni also spoke calmly.

"You're really disappointed." Xu Shuwei ripped off one of the chicken legs of the fried chicken and stuffed it into his mouth.

"It's not completely meaningless, at least we can confirm that there will be a lot of carbon in this mining area, which can be collected and is a good material for making graphene. From this point of view, it is good news. At least our next lot of graphene needs have been addressed. Chen Mengchuan said.

Now as today's graphene technology has developed faster than the original, after the completion of the single crystal graphene technology, the graphene team has pulled out an additional project team, specializing in graphene nanotechnology, and with the attention after the project, now more and more people are now increasing, and the Mars base has also built a graphene scientific research base, planning to start large-scale research and development of graphene nanotechnology.

The large number of product directions hanging in the project team made Chen Mengchuan look forward to it......

If graphene nanotechnology can be completed, then many of the next technologies can be promoted faster!
