Many people are already pasting Spring Festival couplets and buying new year's goods.
Huang Haojie is still busy in various research institutes.
Under strong pressure, the semi-finished dark red sub-metallic oxygen is slowly transforming.
Li Xiang looked at the instrument parameters and then recorded some data.
After these days of experiments, the Materials Research Institute has successfully improved the stability of submetallic oxygen (dark red) to a very good state.
At this time, the density of submetallic oxygen (dark red) reaches 1971 kilograms per cubic meter and can be maintained at standard atmospheric pressure below 46 degrees Celsius.
Below 46 degrees Celsius is the stable zone, 46 to 76 degrees Celsius is the relatively stable zone, and above 76 degrees Celsius is the unstable zone.
After a while, the semi-finished metallic oxygen (dark red) in the instrument has changed into a denser and stable metallic oxygen state.
The researchers took out the stabilized submetallic oxygen from the instrument and took it to the laboratory for testing.
"Ordinary submetallic oxides are no longer a problem and can be produced on a large scale soon. However, it is difficult to produce induced submetallic oxides." Li Xiang said helplessly to Huang Haojie.
Huang Haojie has already read the experimental report. The conduction of submetallic oxide is also a light blue submetallic oxide. The reason why it is said that the conduction of submetallic oxide is difficult is mainly due to the problem of mutation.
At first, Li Xiang's experiment went smoothly. Within three days, they raised the maintenance temperature of the conductive metal oxygen to about minus 23 degrees Celsius.
However, after entering minus 23 degrees Celsius, the properties of the conductive metallic oxygen suddenly disappeared. After the pressure exceeded the critical point, the conductive properties of the conductive metallic oxygen suddenly disappeared.
The whole piece conducts submetallic oxygen, and after breaking through the critical point, it turns into dark red stable submetallic oxygen.
"There's a long way to go!" Huang Junjie spread his hands helplessly.
"I'm really not willing to give in! If the conductive metal oxygen can be stored at room temperature, the production cost will definitely not be as expensive as that of iron and silver conductors at room temperature." Li Xiang said unwillingly.
"Scientific research is not infrastructure. Sometimes what we lack is a little bit of luck."
"I plan to continue the normal temperature conductor project, how about it?"
"You are the director of the Materials Research Institute, you decide for yourself."
"Then continue with this project."
"Actually, we don't have to dig deep. There are still a lot of elements on the periodic table. Why not try other elements." Huang Haojie suggested.
Li Xiang looked at him in surprise: "Why didn't I think of it?"
"The authorities are obsessed with it," Huang Junjie replied with a smile.
"If I choose other elements, I would consider nitrogen and sulfur to start with." Li wanted to name two elements.
Huang Junjie was not surprised by this answer. The reason why he chose nitrogen and sulfur was mainly because of their large reserves and easy availability.
And those rare elements are not among the first considerations.
After all, Galaxy Technology itself has iron-silver normal-temperature conductors. If the cost of the newly developed normal-temperature conductors is still the same, what do I need from you?
Therefore, rare elements are eliminated first. Rare gases such as helium and tellurium, which are also oxygen group elements, do not need to be considered.
Even if it is developed, the price will definitely be very impressive, so there is no need to do this kind of useless work.
Therefore, nitrogen, which is the most abundant gas in the atmosphere, and sulfur, which is among the oxygen group elements, are the choices for experiments.
As for other elements, let’s wait until the results of nitrogen and sulfur come out.
"Then I wish you success immediately."
"I hope everything goes well!" Li Xiang replied, raising his glasses.
"By the way, Happy New Year!"
"Um...it's New Year already?"
"..." Huang Junjie didn't know how to answer this question.
"See if you are free." Li Xiang said to himself, opening the holographic bracelet, and then looking at his schedule:
"It will be held on the 6th...on the 7th..." He muttered while flipping through the schedule.
"Forget it, just make a phone call and go back."
"Let's go home and spend New Year's Eve at home!" Huang Junjie couldn't stand it anymore.
This guy is too obsessed with research work. He stays in the institute all day long and never goes home. Although his villa is less than three kilometers away from the institute, there are only a handful of days he can go back to it throughout the year.
Fortunately, Li Xiang is not an only child, otherwise his parents would not be happy even if they lived in a villa.
A typical scientific research geek is someone like Li Xiang, a man who has a laboratory where he doesn't even need a woman.
"When is New Year's Eve?"
"No. 4, the day after tomorrow." Huang Junjie replied helplessly.
"No, I have one on the 4th..."
"As big as you are! Put everything back one day, and you have to take this leave if you don't want it! Otherwise, I'll ask Cheng'an to ask someone to kidnap you back."
Damn it! I have to enforce it even if I take a holiday. Do you think it’s easy for me?
Watching Li Xiang reluctantly return to the laboratory.
He almost spit out his blood. Others are eager to take a vacation every day, but these guys are eager to work overtime every day.
Of course, this has something to do with the scientific research system of Galaxy Technology. After all, those researchers who have made great achievements are definitely diamond kings.
Just like Li Xiang can easily earn more than one billion yuan a year, and Dr. Yuan Quan of the Seawater Desalination Research Institute can also earn more than one billion yuan a year by relying on seawater desalination membranes and gold extraction membranes.
Although there are only a few top researchers with this kind of income, even an ordinary researcher can easily earn one million a year.
Moreover, their money is not put in the bank to deposit interest, but is invested by the Mars Group's trust fund. The annual growth rate is generally around 5 to 15%.
In addition, Galaxy Technology will give employees shares, rewards or quotas from some of its companies.
Employees at Galaxy Technology are all high-income earners, so many employees work very hard in order not to lose their jobs.
Researchers, on the other hand, are interested in patent fees and shares.
…
Huang Haojie asked Zhong to inform the institute management committee and ask them to formulate a holiday and rest plan as soon as possible to prevent some researchers from being in the institute all day long. If something happens, it will not only be a loss, but also a trouble.
After arranging this matter, Huang Junjie came to the Hydrogen and Oxygen Motive Research Institute.
Inside the mountain laboratory of the institute.
Huang Haojie and director Qin Tongxing were watching the testing of a rocket engine.
Boom boom boom...
The light blue tail flame, even through the thick protective glass, can still feel the violence contained in the motive.
On the instruments on the side, Huang Junjie looked at two important parameters of the rocket engine, specific impulse and thrust.
[Specific impulse: 372 seconds...377 seconds...]
[Thrust: 547 tons.]
The specific impulse is still beating continuously.
Specific impulse is the momentum that can be generated per unit of fuel, which means combustion efficiency. In layman's terms, it means whether it is resistant to burning or not.
The greater the specific impulse of the rocket engine, the greater the load. This applies to any situation.
The greater the thrust of the rocket motor and the greater the load, the effect is obvious in the first stage, less obvious in the second stage, and the impact in the third stage is very small.
Therefore, generally speaking, the first stage or booster uses kerosene and solid motors with large thrust and relatively small specific impulse, while the second and third stages generally use hydrogen-oxygen motors with small thrust and high specific impulse.
However, the hydrogen-oxygen engine does not necessarily have low thrust, it is just that the technology cannot meet the requirements for large thrust.
