Zhu Tian: The Fiery Years Begin with Taking Qin Huairu as a Concubine

Chapter 191 We Are the World's Number One
Several graduate students and professors from the Chemistry Department reacted immediately.

The simplest is ethyl acetate solution, which is often used as a biological extraction solution and is a common raw material in laboratories.

A group of professors and graduate students from the Department of Chemistry shouted anxiously:

"Ethyl acetate! Ethyl acetate!? Use it to do a two-way extraction experiment!?"

Zhang Kaiwu nodded and said with a smile:

"You can also consider adding some activated carbon powder to further decolorize and remove impurities during this process. The more times you repeatedly extract with ethyl acetate and wash with distilled water, the higher the purity of penicillin should be. Now you can experiment on your own. This small experiment should not be difficult for your chemistry group."

Hu Shuangjiu raised his hand gently and said:

"Senior! Won't the structure of this penicillin be destroyed?!"

Zhang Kaiwu smiled and said:

"If the penicillin crystals are truly high-purity and do not contain those impurities, their structure is relatively stable. This is why they can be stored at room temperature."

"If there is an azeotropic extraction machine in the laboratory, the experiment will be much simpler and the time will be much faster."

"You just need to pay attention to the purification temperature and not destroy the thermal structure of penicillin. Also, divide into groups and record the ratio and concentration of the ethyl acetate solution each time, and find the best double-sided extraction concentration. Let's start the experiment!"

Hu Shuangjiu and a group of classmates and professors started to work on it. This is how the penicillin extraction experiment was done. Knowing the method and precautions, middle school students can also do it at home.

If you don't know its characteristics, it will take a lot of time to explore.

However, penicillin extraction is time-sensitive. If it fails in the first attempt or the temperature and time are not controlled well, the penicillin solution will be damaged.

You will need to culture the penicillin solution a second time before you can do the second experiment, which is really troublesome.

Following the tips given by Zhang Kaiwu and avoiding those problems, it is really not difficult to extract penicillin crystals using the conditions in the laboratory.

Hu Shuangjiu and a group of people were there mixing ethyl acetate solutions and taking notes.

A group of people were busy.

...........................

After a busy afternoon, it's now time for dinner, but these people are very excited and probably won't be hungry.

Zhang Kaiwu sat down, rubbed Zhu Zhiyin's belly, and asked in a low voice:
"Xiao Yinyin! Is the baby in your belly hungry? Otherwise, ask them to send you something to fill your stomach first!"

Zhu Zhiyin handed him a cup of tea and said shyly:

"Kaiwu! You are still talking nonsense here at such a solemn moment. I am only a month pregnant. How can I be so scary?"

Zhang Kaiwu rubbed her gently and said, "When I wanted to eat rice with crusty rice or pork ribs stewed with potatoes, I remember you often threatened me with your stomach."

Everyone else in the lab was silent, except for a few impatient old men who would quietly run over from time to time to check on the progress.

But no one dared to make a sound to disturb them, for fear of disrupting the experimental work.

Seeing the nervous look on Dean Zhu's faces, Zhang Kaiwu asked with a smile:
"President Zhu, President Zhou, don't worry so much. It's just a penicillin extraction experiment. It's very simple. Why did you come to watch the fun so quickly? "

Dean Zhu and Dean Zhou looked at him speechlessly, too sad to talk to him. Don't you know what a great honor this is! ?
What does it mean you don’t know! ?

You, Zhang Kaiwu, are the pride of our medical school. You are not from Yenching University, and you are not from Tsinghua University!

What kind of important experiment is being done here! ?

Fortunately, a classmate from the medical school answered the phone and heard about this and informed them.

Otherwise, wouldn’t it be a pity if they were not there to witness such an important honorary moment in the medical school? ?

Dean Zhou smiled and said:

"Brother Kaiwu! From now on, if you need anything in your laboratory, just ask for it. Important experiments like this can be done in the medical school."

"We are all flexible and we are not old-fashioned people. There is no need to come to Yanjing to conduct experiments."

The young old man Lu suddenly became annoyed and asked:

"What's wrong with our school? Do you have a biology department in your medical school? Have you started the penicillin culture experiment? You don't even have a good spectrometer. Do you have an extraction machine? How long does it take to do a simple extraction experiment? Half a year?"

"Brother Kaiwu! I will call you this from now on. If you need anything, just come to our school to borrow the laboratory. If you have any requests, just let us know. We can do it as long as we can."

Hehehehe! Poaching people right in front of them! ?
Dean Zhu said with a smile:

"We don't have those things, but you can just use the money from our medical school to buy them. You can keep them for your own use, and we will buy new machines for you."

"Zhiyin! You have to keep an eye on Kaiwu, otherwise what will happen to Kaiwu's children? Some people just don't respect their elders. You heard what he said just now, he actually said something about free love!? Encouraging students to destroy other people's families is really unreasonable!"

Zhu Zhiyin hugged Zhang Kaiwu and smiled gently, she was really embarrassed to respond!
She is just the fourth concubine!

Zhang Kaiwu smiled and didn't bother to pay attention to these old men. He was a serious man.

Another old dean said quickly:

"If I remember correctly, Hu Shuangjiu, a graduate student in our school's chemistry department, is now dating Kaiwu, right? Let young people solve their own problems. What are you yelling about, Old Zhu? "

Director Liu, who was on guard duty, smiled and remembered that Zhang Kaiwu had gone to sell stockings in the morning. He also said quickly:

"Senior! You are an excellent researcher, but you have not yet mastered the method of living a happy life. You can come here to learn about art in your spare time, and come to our school more often in the future. We have advanced experience in this area."

"The girls are interested in artistry, so it doesn't matter if the seniors don't understand, they will teach you with passion!"

Zhang Kaiwu was calm and composed, as if he didn't even know Director Liu, whom he had just met in the morning.

I have never been to the Academic Affairs Office. Who are you?
The young old man Lu smiled and said:

"That's what I mean. Dating is not a one-time deal or business. Everything is possible! Lao Zhu! You can date now. It's not too late. This doesn't mean you have a reason just because you are the loudest."

Another old man said quickly:

"That makes sense! Maybe Old Zhu can give birth to a son. Everything is possible!"

"You guys in the medical school, running around with a broken box every day, you don't understand the romance of life at all!"

Seeing that Dean Zhu was speechless due to their overwhelming strength, Dean Zhou angrily helped and said:

"You bunch of shameless old people, remember this: don't come to our hospital for treatment in the future. If you see me, I will at least use the largest needle and give you ninety-nine eighty-one injections!"

"I'll show you what needle pain is like!"

Ha ha ha ha ha!
A few old men started to quarrel and talked about the love story of the Republic of China!
More than another hour passed.

Suddenly, Hu Shuangjiu and his colleagues from the Chemistry Group cheered. After the double back-extraction experiment, a handful of white crystals appeared in the azeotropic extraction machine.

Classmates, professors, tears are streaming down your face...

Song Fuzhi, Song Fuhui and others took the crystal powder and did spectral analysis.

The remaining chemistry graduate students and professors had no intention of continuing the experiment and stared at the analysis results nervously!

The group of old men had no time to argue with each other. They all stared at the analytical instruments excitedly and clenched their fists.

Hu Shuangjiu stared at the analytical instrument and said excitedly:

"Penicillin crystals! These are penicillin crystals! We succeeded, classmates! We really succeeded!"

She jumped off the instrument operating table, ran over excitedly, and gave Zhang Kaiwu a kiss.

Zhang Kaiwu took Hu Shuangjiu to introduce him to Zhu Zhiyin, and said with a smile:
"This is Hu Shuangjiu from Tsinghua University, and this is Zhu Zhiyin. Xiaojiu will also be a sister in the family in the future."

Hu Shuangjiu said shyly:

"Hello, Sister Zhiyin!"

Zhu Zhiyin said with a smile:
"Hello, sister Xiaojiu! We are all family, so don't be polite. Tell me how you met Kaiwu?" Zhang Kaiwu said quickly:
"Xiao Jiu and I fell in love at first sight, like dry wood meeting fire! If you keep talking about these things, those old guys will start a fight."

Hu Shuangjiu smiled gently. She certainly wouldn't explain that she knew him because she was selling stockings. The one selling stockings was Brother Chu. What did he have to do with Zhang Kaiwu who was doing the experiment?

Sisters Song Fuhui and Song Fuzhi looked at Xiaojiu and Zhang Kaiwu chatting with envy.

The senior’s demeanor is so charming!
.....................

Several old men were crowded there looking at the spectrometer. The young old man Lu pushed aside Dean Zhou and Dean Zhu who were trying to squeeze in and said:
"What are you doing here? You are two doctors. Can you understand the data from this instrument?"

Dean Zhou and Dean Zhu retreated with gritted teeth. They were both doctors and knew how to use penicillin, but they really couldn't understand this instrument.

There were also a few old guys from the biology department. They had experience and got some penicillin crystal powder, which they eagerly observed under a microscope. They had seen this stuff too many times.

They have looked at the miracle medicine of the Beautiful Country countless times and dreamed that one day they would be able to make it themselves. They can recognize penicillin crystals by their appearance!
In fact, everyone who doesn’t do instrumental analysis knows that this time it was truly a success.

Dean Zhou and Dean Zhu could understand the microscope, but they could only watch from the side. They could only watch and could not recognize the penicillin crystals.

So anxious that my feet jumped up and down!
It wasn't long before the penicillin was confirmed and the remaining penicillin solution was extracted.

Dean Lu was well-informed and was so excited that he kept mumbling:

"This is not procaine penicillin crystal. This is the same penicillin crystal as in the United States. This is a crystal that can be stored at room temperature!"

An old dean stared at the crystals and said unconsciously:
"So that's how it is! So that's how it is! Senior's method is actually much more advanced than theirs!"

"The technology of the United States is nothing, we are the best in the world!!!"

Dean Zhu and Dean Zhou looked at the white crystals, their eyes became moist, and they kept wiping their eyes.

Once the miracle drug comes out, the treatment of many diseases becomes very simple.

Penicillin is now sold on the black market at a price of 100,000 units per gram in a small bottle.

One case of syphilis requires more than seven injections!
A bottle of about 30 grams of white penicillin was divided into three bottles, one bottle for each school.

Now we just need to do activity analysis and sterilization effect experiments to see the penicillin content per unit.

None of those things matter!

What is important is that they can proudly say:
We overcame the difficulties and mastered the process. We can not only produce penicillin, but also extract penicillin that can be stored at room temperature!

A group of people passed the news on, and the school was in an uproar. Students were celebrating everywhere, and people were making phone calls to inform others of the news.

.....................

The commotion is over!

It was almost ten o'clock in the evening, and a large group of people were rushing to the restaurant to eat, smiling. They surrounded Zhang Kaiwu and tried to get him to change schools.

The chefs used all their skills to prepare several tables full of celebratory banquets.

The young dean named Lu said with a smile:

“Brother Kaiwu! Eat some vegetables! It’s a pity for a professional like you to be a doctor or something like that.”

"You were able to lead and complete the experiment. This fact itself proves that you are a professional professor of biology and chemistry and a research talent. Our school needs talents like you."

"I heard that you are not specialized in penicillin research, but are going to study the removal of toxic side effects of erythromycin!? The medical school is not bad, but they are after all specialized in training doctors. Our school is willing to support and invest in outstanding talents like you in any way possible."

"The research conditions in our school are much better than those in the medical school. We are willing to set up a professional laboratory immediately and hire graduate students and professors in biology and chemistry to help you."

Ha ha ha ha ha!
Zhang Kaiwu looked at the nervous Dean Zhou and the others and said with a smile:

"Brother Lu! I still like the environment in the medical school. My wives and concubines are all there. I have already started to build my erythromycin laboratory. Now I just lack some things and some sub-equipment. The medical school will find a way."

"As for the lack of biological and chemical researchers, I will also try to recruit them."

"If I can't get the budget, I will go begging to keep running it!"

Dean Zhu said with a smile:
"Kaiwu! Don't worry! We will apply for the necessary things right away, and you don't even have to ask for additional budget."

Dean Zhou said with a smile:
"I will go and ask for the money myself tomorrow morning. I will first give you an additional 2 million in research funding. For a researcher like you, it is only right that you ask for a budget no matter how much you ask for."

"You deserve the top professor treatment. You have been approved in school before, it's just a matter of time to report. I believe no one will have any objections now, brother Kaiwu, don't worry."

"Your achievements in researching penicillin are obvious to all. We will definitely apply for a reward for you. Don't worry."

………………

What are wives and concubines?!

A real man should not worry about not having a wife! ?

Principal Lu said with a smile:
"Brother Kaiwu! If you are not happy in the medical school, just come to our school. We have the most beautiful girls in our school, and they are open-minded and have lovely souls!"

"Especially in the Department of Diplomacy and Art, there are so many beautiful girls there. For outstanding talents like you, they will flock to them like moths to a flame."

"They will be like crazy, wanting to conquer you and wanting to exchange ideas with you alone!"

Dean Zhou looked at him and said angrily:

"Old Lu! Have some shame! You are the principal now, stop laughing and saying these nonsense!"

"Especially in front of young people, you have to act like a principal! Don't let the tricks you and Old Hu used to visit brothels corrupt the talented seniors in our medical school!"

Dean Zhu smiled and said to Zhu Zhiyin:
"Zhiyin! Look at some people, they are just like this. Even if they become the principal, they are still as unruly as ever!"

Principal Lu said with a smile:
"You two old guys are really brave. You came to our school and even dared to exclude us at the celebration banquet."

"Today is such a happy day, don't try to get away with it, everyone drink up!"

Today's event was so joyful that everyone drank a lot and kept toasting Zhang Kaiwu.

Although Zhang Kaiwu basically used the storage space to cheat and put it away. But seeing that this group of old men were almost done, there was no other way, Zhang Kaiwu could only pretend to be drunk.

Otherwise, those old men would still drink as much as they could.

Xiaojiu and Zhu Zhiyin supported Zuixun and Zhang Kaiwu, preparing to go back.

Sisters Song Fuhui and Song Fuzhi saw this and thought, if the senior ran away today, wouldn’t it be a pity! ?
Song Fuzhi quickly said with a smile:
"Sister Zhiyin! The seniors are all drunk, and it's too late. You and Xiaojiu should squeeze in with us today. Our dormitory is also very big, with three rooms."

"We'll make a room for you. You and your senior will sleep in that room."

Zhu Zhiyin looked over and saw that Dean Zhu and Dean Zhou had also been knocked down and were carried away by several principals. No one knew where they went.

The two sisters also had their own ideas. When they came just now, they were still hugging Zhang Kaiwu and chewing him. Zhu Zhiyin knew about it. As for how to deal with it, Zhang Kaiwu would naturally arrange it.

Of course Zhu Zhiyin knew that Zhang Kaiwu was not drunk, he was just pretending to be drunk. It was not difficult to support such a big man.

She smiled and said:

"Thank you for your help, let's go!"

........................

A group of people came to Song Fuzhi's dormitory. They were too lazy to pretend to be armed, and pretending to be drunk was tiring.

He laughed and pulled Xiaojiu and Zhiyin to wash up.

In Song Fuzhi's room, she turned around excitedly, looking at the notebook in her hand as if she was looking at a treasure.

Muttering:

"Senior! It's really the proud senior Zhang Kaiwu! The way he directed everyone to do the experiment just now was simply too charming! Zhihui! Do you think the senior is charming!?"
