Hearing that there was a problem with the pro-nucleus replacement link, Xu Yun didn't even frown and asked in a calm tone:
"Xiao Zhao, there are many possibilities for the failure of the substitution reaction. What is the specific situation? Is it because the substance does not react?"
"The reaction is..."
Xiao Zhao scratched his hair in confusion, his eyes flashed with confusion:
"Logically speaking, the balance formula should be fine, but there is no product produced, well, not even a crude product..."
"How much bipyridine?"
"3eq%."
"I understand, just wait."
When Xu Yun heard this, he immediately picked up a pen and paper and started calculating on the table, with a calm expression on his face.
He was not deliberately pretending to be serious at this time, but he really felt that this matter was not a big deal - he had participated in many large-scale physics research projects in his previous life, and the cost of some major projects was much higher in ten seconds.
Millions (including equipment losses), a slight mistake may cause all previous efforts to be wasted.
Nowadays, the total funding for this project is less than one million yuan, and the first batch of cash flow disbursements is only 50,000 yuan. It is strange to make him nervous.
After a moment, Xu Yun gently threw the pen and looked at Xiao Zhao:
"CuI 4eq%, add bipyridine to 4eq%, 170 degrees... No, try refluxing at 180 degrees for 3 hours."
Xu Yun and others made adequate preparations to avoid light before the experiment, and did not need to consider the possibility of decomposition of the raw iodide. Therefore, no product was produced in the substitution reaction, and the problem most likely lies in the ring.
After dealing with Xiao Zhao's question, Zhou Peiyao, another girl in the research group besides Tang Yiqiu, raised her hand again:
"Senior, there is also a problem with the epoxy ring opening!"
"Don't worry, you can also explain in detail..."
In this way, during the first half of the entire research group's experiment, Xu Yun basically dealt with the issues of team running-in and compound balancing.
After all, except for Qiu Sheng, the other five tool men present were all under Yan 3 or below.
For example, Xiao Zhao, whom Xu Yun mentioned just now, is in the second year of graduate school, Li Yan, Zhou Peiyao and another boy are in the first year of graduate school, and Tang Yiqiu is only a senior in college.
They may be able to solve the problems on paper easily, but when it comes to practical experience...
Almost zero.
As a result, Xu Yun guided and corrected mistakes at the same time, and time passed by minute by second.
"call--"
A few hours later, Xu Yunchang took out a breath and looked at his watch. It read 11:30 noon.
This time he formulated a preparatory process with a total of 22 steps. After one morning, the research team slowly advanced to the step of catalytic hydrogenation of nickel acetate/sodium borohydride, with a completion rate of about 36%.
According to this progress, the progress may be raised to about 60% today.
If you are lucky tomorrow, you may be able to complete all the preparatory work.
The laboratory's useful life is two weeks, which means that Xu Yuneng has about 12 days to work on the synthesis.
This was a little faster than he expected - after all, the mission reward was the formula of the fifth-generation imidacloprid. Xu Yun was currently tinkering with the fourth-generation imidacloprid, except for the cyclization idea, almost every step had to be worked on by himself.
Then he quickly glanced around the laboratory and found that all aspects had almost entered the observation period. He coughed lightly and said:
"Okay, let's stop what we are doing and go have lunch before continuing.
Lao Qiu, please show your style and stay in the laboratory for a while. I will take a few junior students to the US Broadcasting Corporation for a meal, and then I will replace you after we are done."
As the deputy of the research team and one of the only doctoral students on site, Qiu Sheng is considered the most suitable candidate for duty, so he nodded happily after hearing this:
"I understand. You can go and eat without worry. The laboratory will be left to my dad."
After deciding who was on duty, the group changed into regular clothes in accordance with the experimental regulations, and headed towards USTC Meiguang under the leadership of Xu Yun.
The so-called Meiguang refers to the abbreviation of Food Court, which is also a very famous food gathering place around the University of Science and Technology.
Xu Yun studied for a regular undergraduate degree in her previous life. The uncle of a classmate in the same major opened a barbecue restaurant next to the US Broadcasting Corporation, and her boyfriend was from the animal and plant life, so every week he and his roommate would start from experiments.
I stole a few rabbits out of my room and took my girlfriend and her roommate to a barbecue restaurant to cook some seasonings. In the end, six of the eight people in the two dormitories became lovers...
This tradition continued until after Xu Yun graduated. I heard that a funny guy accidentally brought out a rabbit that had taken medicine, which eventually caused a group of people to have diarrhea and went to the hospital. Since then, the HKUST laboratory has been strictly
A lot...
Xu Yun and his party were talking and laughing like this, and finally arrived in front of a grilled fish restaurant.
I don’t know since when, many single-person grilled fish restaurants have appeared in the local area. The average price per person is less than 30 yuan, which is indeed very friendly for office workers or social workers.
After entering the store, Xu Yun and the six of them each ordered their favorite flavors and then took their seats...
I refreshed my phone.
There is no way, this is the standard social model for contemporary young people, and they simply cannot live without their mobile phones.
Tang Yiqiu and Zhou Peiyao are both standard melon-eaters. After opening Weibo, they immediately locked onto the hot search list:
"Eh? The poster of the Three Rats is overturned. I quite like their snacks..."
"Didn't the comments below say that this was a poster from 19 years ago, and now it has been dug out to bring out the rhythm."
"What, co-authoring it has been causing trouble since 19 years?"
"Well, you seem to be right in saying that..."
"Look at this again. The new book by Qidian.com author "Novice Fisherman" is on the market. He is starving and comatose at home. Isn't this too pitiful?"
Looking at Balabala's junior students, Xu Yun couldn't help but have a smile on his face.
He actually liked the atmosphere of a group of chattering people, but unfortunately after graduation, various pressures and real problems came one after another, so gatherings among colleagues no longer had this flavor.
I still miss the days without intrigue...
But at this moment, Li Yan on the side suddenly let out a long ‘huh?’:
"Everyone, look at the number 8 trending search. Isn't this funny?"
Li Yan's words immediately attracted the attention of everyone at the table. Seeing that several people had not downloaded Weibo, Li Yan directly turned on his phone and displayed the content page:
"Look."
Xiao Zhao, who was closest to him, immediately came forward, reading and repeating:
"#NewtonPortrait,Anta#? Um, what kind of hot search is this?"
Li Yan chuckled when he heard this:
"A well-known British collector just passed away. Before his death, he donated all his collections to the British Museum. Today the museum held an admission ceremony and invited a bunch of media to visit.
Among them was a standing portrait of Newton, said to have been painted in 1701, but someone saw a pair of sneakers on the table behind the portrait."
"sports shoes?"
Li Yan nodded vigorously and grinned wider:
"Yes, it looks like this year's winter model from Anta. Now some people say that Newton is a Chinese traveler, and some people accuse Anta of engaging in malicious marketing - but the problem is that Anta had just withdrawn from BCI in Zhuzhou Mian, and the entrance ceremony
The broadcaster is still BXC, and it is impossible both emotionally and rationally to cooperate in such a thing."
Zhou Peiyao thought for a while and asked:
“Is it possible that the domestic marketing accounts made up the news themselves?”
Li Min shook his head:
"It's impossible. Some juniors and girls in the college who are studying abroad have said this. I heard that the foreign media are going crazy. Regardless of the final outcome of this matter, John Bull's face has been completely humiliated. Xu Shen
Am I right?"
Facing Li Yan's inquiry, Xu Yun hummed mechanically, as if a thousand ears were jumping in his heart:
The sneakers in the portrait, are these the Easter eggs that come as rewards?
