Chapter 551 Difficult Road
A week later, the new semester of Suiren University is about to begin, and more and more students are returning to school.
Xie Qing's other three classmates also returned to school one after another. After hearing the idea of electric field synthesis, they did not agree immediately.
In the end, only one girl among them participated in Xie Qing's electric field synthesis group, and the other two planned to follow the traditional chemical synthesis route.
Xie Qing did not force this, after all, everyone has his own ambitions.
The new fall semester of 2014.
Their instructor only communicated with the five people through online video, and then hurriedly ended the video conversation.
Xie Qing and others are used to this. Associate tutor Qiu Datong gives daily lectures and heart-to-heart talks, or arranges for them to participate in open classes of other materials science professors.
Xie Qing, who had a lot of spare time, used the credits of the three of them to apply for some experimental equipment, including electrostatic field generators, variable frequency lasers, reactors and some chemical raw materials.
Their credits are very useful in school, and this is also one of the ways to encourage students to actively learn.
The more credits they have, the more scientific research funds they can apply for, and the more advanced the scientific research equipment and laboratories are. As top academics, Xie Qing and the others naturally have a lot of credits.
These credits are enough for them to apply for better laboratories and even customize some special scientific research equipment and precision instruments.
September 28th.
After attending a class, Xie Qing saw the rolling advertising screen on the roadside broadcasting live broadcasts of the situation on the other side of the moon.
Stopped involuntarily.
At this time, the remaining two space capsules have been deployed at the Guanghan Palace base on the moon. The five space capsules assembled from orbit are in an upright state; while the two space capsules assembled on the lunar surface are lying flat. On the ground.
The base itself has a magnetic field protection cabin, which can deploy the magnetic field protection system to ensure that it will not be attacked by solar storms.
The unfolded solar panels are about 12 meters above the ground. The reason for choosing such a high location is mainly to avoid floating moon dust from adhering to the surface of the solar panels.
Lunar dust on the lunar surface is very easy to generate static electricity, and then adheres to the surface of the spacecraft. This electrostatic effect not only makes the lunar dust extremely difficult to remove, but is also very easy to be ionized by the solar wind and turn into long-term floating lunar dust.
In the live broadcast, astronaut Shi Keji climbed up to the elevated solar panel. He first used a long-pole static eliminator to eliminate the static electricity of moon dust on the surface of the panel, and then used an electrostatic roller dust collector to suck away the moon dust on the surface. .
The panel dust is usually cleaned once a month on average. This can ensure that the efficiency of the panel is at its highest level for a long time.
If it is a period of frequent solar storms, the cleaning interval needs to be shortened.
The scene changes.
Nie Changfeng, who was in the experimental cabin, was doing a simple chemical experiment, although he had already tried chemical synthesis under low gravity in the Tiangong space station.
But this time the chemical experiment was still unsatisfactory.
Xie Qing also knows the trouble involved. Traditional chemistry in outer space needs to consider more variables and possible link failures.
After watching the moon live broadcast for more than half an hour, he walked towards the canteen while thinking.
Cheng Cunwu and another female classmate Xiong Lingxi had already packed their meals and were already eating.
After he came over, he started eating directly.
"How is the chemistry experiment going live on the moon?"
Xie Qing shook his head: "It's not ideal. The traditional chemical reaction path is complicated. After all, there is a saying in the chemical industry, dirty chemistry."
The so-called dirty chemistry refers to the ultra-complex synthesis pathways in the current human chemical industry.
People who are not engaged in this field may think that the process of chemical synthesis is A+B=C, or A+B=C+D.
But the actual modern chemical synthesis may be like this: A+B=G+J+catalyst=H+S+catalyst=...=C.
There are four or five intermediate links, which is already a very simple synthesis path, and a dozen intermediate links are not uncommon.
Moreover, a large amount of by-products will be produced during the synthesis process. The reactants in the reactor may be comparable to a pot of Shiquan Dabu Decoction, and then the required compounds can be extracted from them and entered into the next step of reaction synthesis.
Repeating similar processes often requires more than a dozen synthesis links from raw materials to final products.
No wonder chemists describe the chemical synthesis process as dirty.
Modern chemistry is no longer the chemistry of ancient times. As the physical and chemical properties of simple compounds have been used to the extreme by humans, humans have to synthesize new and more complex compounds.
These new compounds often cannot be achieved in one step and require complex synthetic pathways to obtain the final product.
Even though the current Guanghan Palace base can barely synthesize some simple compounds, once it gets down to relatively complex compounds, no chemist dares to guarantee that they can come up with an efficient and low-cost synthesis plan in a short time.
Xie Qing took a mouthful of rice and continued: "We need to simplify the complex and start from the fundamentals of chemical reactions to solve the current dilemma."
Xiong Lingxi on the side nodded: "I agree. The root of chemical reactions is actually the change of chemical bonds, and chemical bonds are ultimately the transfer of electrons between atoms and molecules."
From the fundamental point of view of chemical reactions, electric field synthesis technology is a simple route.
But that’s easier said than done.
An electric field can change the state of electrons in molecules, but how large an electric field is required? Are other auxiliary conditions needed in the electric field? What are the energy consumption and costs of electric field synthesis?
Problems like this are an unsystematic mess. If they want to integrate electric field synthesis technology from a chaotic situation into a complete system, Xie Qing and others still have a long way to go.
After lunch, since there were no classes in the afternoon, the three of them went to their group's dedicated laboratory.
After registering today's experimental plan and possible dangers with the laboratory management department, they entered the laboratory.
Schools have relatively strict management of laboratories such as chemistry and biology, mainly because they are worried about experimental accidents.
The three people put on inner protective clothing and gas helmets, and also put on a work-type exoskeleton, equipped with an exoskeleton just in case.
Once a dangerous situation occurs, the exoskeleton's emergency escape system can be activated, and the exoskeleton will automatically leave the danger area.
Even if the user loses consciousness or loses mobility, the exoskeleton can be remotely controlled by the laboratory management department.
Xie Qing carefully prepared the experiment according to strict experimental procedures.
In terms of safety, several people have not taken it lightly. Illegal operations are not only a joke with their own lives, but also will result in credits being deducted. At the same time, the review of applications for funds and instruments will be more stringent.
In line with the idea of devoid of development and not wasteful, the three of them operated carefully.
Their experiment today is to use carbon powder in amorphous carbon as raw material to experimentally synthesize carbon allotropes such as graphene, fullerene, carbon fiber, and diamond.
A spoonful of toner was put into the reactor.
Immediately, Xie Qing started the electrostatic field generator, so that the entire reactor was covered by the electrostatic field.
They adjusted the intensity of the electric field little by little. At each intensity, they took out the carbon powder in the reactor, conducted laboratory analysis, and then recorded the changes.
Chemistry and materials research are sometimes so boring and boring. It is a process of constant trial and error.
