Chapter 1228 Postscript 84·I actually brought back pumpkins and tomatoes
"Sister, don't lie down all the time. Get up and take a walk."
"I'm afraid of falling."
"It's okay, get up and take a walk."
"Haha, I've long been tired of lying down, so it's more comfortable to stand. Liulang, please help me, I'm afraid of falling..."
Qingluan stood aside and watched with a smile, thinking: The princess has so many little thoughts. Why should she hold her up if she is afraid of falling? She just wants Liulang to pay more attention to her.
Alas, Mukuro will probably accompany the princess tonight. Will he come to make out with me tomorrow night?
Qingluan recalled the various scenes she had peeped at, and couldn't help but blush. She didn't know what kind of moves Liulang would use for the first time with her, or maybe it would be a complete set of solutions.
"Mr. Lang, the time has come." A maid came to remind.
Zhu Tangxi then asked Xie Yan to let go of him: "Liu Lang, go and freshen up. Don't go into the palace. It would be disrespectful to you."
Xie Yan gave a few more instructions and then went back to the dressing room to dress up.
In the Tang Dynasty, the cloakroom specifically referred to the cloakroom, but in the Song Dynasty it also generally referred to the cabinets for storing clothes.
Several maids immediately followed and took out a set of clothes that the princess had already chosen for her.
A maid stood holding clothes in her hands, and a maid helped Xie Yan undress. After taking off his clothes, another maid immediately helped him dress.
Xie Yan only needs to raise his arm at the critical moment.
At first, he was a little uncomfortable and felt that there was no need to be surrounded by so many people. But after less than half a month, Xie Yan began to enjoy it. It felt good to have his clothes on and his hands out.
Especially for more complicated outfits, it is really troublesome to wear them by yourself.
After changing his clothes, Xie Yan sat down in front of the dressing table, and a maid helped him comb his hair again, and finally put on a small crown.
Daiyu and Baochai looked on, they needed to learn slowly.
Daiyu is okay, her goal is to become Xie Yan's laboratory assistant and be responsible for the management of the home laboratory.
Baochai positions herself as Xie Yan's personal maid. She must learn how to dress and match clothes, and she even wants to learn massage.
After getting dressed up, Xie Yan looked in the mirror. The handsome guy in the mirror was getting more and more handsome.
It is easy to go from frugality to luxury, but it is difficult to go from luxury to frugality. Alas, how will we live without maids to serve us in the future?
After getting the title of princess, Xie Yan took a car straight to the imperial city.
This time I was led to the side hall of Wenhua Palace by the palace officials.
The current Wenhua Hall was the Wenming Hall in the Northern Song Dynasty. During the Tang Dynasty, the Wenhua Hall was also called Zhenguan Hall.
The layout of the Luoyang Palace in the Northern Song Dynasty has undergone tremendous changes compared to the Sui and Tang Dynasties, including the location of the Civilization Hall.
There were already two people waiting in the side hall, both of whom Xie Yan knew.
One is his pen pal Zhu Shirong, who came specially from Kaifeng this time.
One is Rose Bachelor Shi Huai, who was recently promoted to first vice president of the Chemical Society.
"Junior Xie Yan, I have met Academician Shi and Academician Zhu!" Xie Yan bowed in greeting.
The two of them quickly returned the gift and then sat down to chat.
The content of the conversation was all related to chemistry. They mainly talked about their recent experimental results and what molecular formulas they had determined for each substance.
Not long after, two more people came in one after another.
One is named Zeng Yan and the other is named Lu Churen.
Among them, Lu Churen was summoned from Nanjing. After receiving the telegram, he immediately went north and only arrived in Luoyang yesterday afternoon.
Except for Shi Huai, who is over fifty years old, and Xie Yan, who is only seventeen years old, the other three are all mature scientists in their forties.
The five people were greeting each other when the old president suddenly came with someone.
The old president introduced them: "This is General Zeng Jiuyou who completed the circumnavigation of the world. General Zeng, this is the vice president of the Chemical Society..."
Zeng Jiuyou did not dare to neglect and saluted respectfully.
After some pleasantries, everyone took their seats.
The old president said: "General Zeng brought back a kind of rubber from the United States. This material can be of great use after vulcanization, so the Queen Mother ordered to summon five chemists. Open it..."
The three boxes in the side hall were opened one by one by the palace staff, and they were all filled with rubber.
Zeng Jiuyou pointed to one of the boxes and said: "This is the finished product I exchanged from the indigenous people. There are rubber balls, rubber coats, and rubber boots..."
Xie Yan and four other chemists gathered around and each picked up a rubber object to examine it.
In Xie Yan's hand was a rubber boot, with scattered hairs faintly visible inside.
He could imagine the process of making boots, in which the Native Americans applied rubber to their feet, waited for it to completely solidify, and then peeled it off, ripping out the hair on the insteps and ankles.
Moreover, it was late autumn in Luoyang at this time, and the rubber boots had become harder and more brittle, and there were signs of cracking with just a slight pinch.
Everyone exchanged the items in their hands to observe, and soon they discovered that something was wrong with the rubber ball.
This thing has the best elasticity and is not easy to crack when pinched.
Shi Huai said: "General Zeng, was this ball made using any special method?"
Zeng Jiuyou said:
"After the local indigenous people cut the rubber juice, they usually boil it in a clay pot, and then wait for it to cool and solidify. When it is not completely solidified, they smear it on their feet to make boots, and they also smear it on their bodies to prevent mosquitoes.
of."
"When cooking rubber juice, they add a grape juice (actually a plant of the Urticaceae family with grape-shaped fruits)."
"This kind of rubber ball is different. They determine the human sacrifice by playing with the ball. The winner will be killed and used as a sacrifice to the gods. In order to make the ball more durable, they will also add another thing, which is pinching.
The white juice that emerges from broken sweet potato vines.”
Xie Yan knew nothing about rubber vulcanization, and of course he had no idea what the natives were doing.
Adding the juice of Urticaceae plants actually promotes rubber coagulation through formic acid.
Adding the white juice of the sweet potato vine vulcanizes the rubber through mucus proteins and increases the antioxidant properties of the rubber. However, its vulcanization effect is limited and it can easily cause the rubber to become moldy.
Zhu Shirong guessed: "The American grape juice and sweet potato vine juice may have some chemical reaction with the rubber. The composition of plant juice is complex, and it is difficult for us to find out which substance is responsible."
Zeng Wei pointed to another box and asked, "What kind of rubber is in this?"
Zeng Jiuyou said: "I asked the natives to collect the rubber sap, boil it directly and solidify it. Nothing was added, and it solidified very slowly. When sailing at low latitudes, it was all a soft lump. The weather in Luoyang
As they get colder, they become harder and more brittle."
"Is this the only rubber we got?" Xie Yan asked.
Zeng Jiuyou said: "I brought back two hundred rubber saplings, dozens of which died at sea, and the rest were quickly planted in Luzon. I also brought back thousands of rubber seeds and gave them to agriculturists. As for
Rubber, that’s all.”
Check out the correct version one by one!
Xie Yan said: "There are too few experimental materials and we cannot conduct them separately. Even if we conduct experiments separately, we must allocate the contents of each experiment."
Lu Churen said: "Let's do it together, there is too little rubber and not enough points."
"I can bring some rubber back next year," Zeng Jiuyou said.
Xie Yan and the four chemists started discussing. In fact, when they heard the word "sulfurization", they already pointed out the direction of the experiment.
They quickly confirmed several experimental methods, such as steaming sulfur and rubber together, cutting the rubber into pieces and mixing it with sulfur and heating it, etc.
It's not difficult in the lab.
But if it is to be put into industrial use, there are still more problems that need to be solved.
For example, formic acid (formic acid) has long been discovered by chemists and can be obtained by distilling a large number of ants. However, no one, including Xie Yan, would have thought of using formic acid to promote the coagulation of rubber sap.
It's okay to not add formic acid, but it will require higher temperatures and longer time, which will greatly reduce the efficiency of rubber production.
The old president said: "The vulcanization experiment will be done in the imperial city, and I will arrange a few assistants for you. If you need anything, just tell me."
"yes!"
Xie Yan and the four chemists accepted the order, and then discussed and wrote down the required equipment.
