Siheyuan: I eat melons while doing scientific research

Chapter 1413 Low-Density Shadow (5k)

"Oh, there are clinical trials..." This thing is not used for treatment, but only for testing. These days, the process of participating in clinical trials is much simpler, and you can even start participating before the final specific reagent is available.

For clinicians, since it's free, they might as well use it a little. Besides, they don't participate in actual treatment, but it can still point the way, so why not take advantage of it?

"The authors of this article are backed by a large comprehensive hospital, so it would be easy for them to conduct clinical trials. Moreover, they have extensive experience in clinical trials; you could say that there are no more experienced ones in China." The editor saw the authors and their institutions when receiving the email, but the editor-in-chief was too excited to notice them because he was eager to read the content.

"Do you know the author of the article?" the editor asked with a smile.

"How novel! You recognize it too? That lactamase inhibitor used to combat drug-resistant bacteria, have you forgotten?"

"Ah, it's them. That's not surprising. I was wondering why so many high-level biopharmaceutical researchers have suddenly emerged in China. It turns out it's them." As one of the editors-in-chief of the medical journal, I am quite familiar with Professor Qi and Lou Xiao'e's team. After all, there are not many people who have achieved this level of success in this field.

"This article is great! Take it down, take it down." Saying it's great while simultaneously wanting to remove it? This maneuver has left the editor completely bewildered.

"Editor-in-chief, why? Are you worried they haven't completed patent protection? I've seen it; it was mentioned in the submission email that the patent protection was already in place." How can such a good article be withdrawn so easily?

The editor-in-chief shook his head: "That's not what I meant. What I meant was that it's a waste to publish it in our journal. We should publish it abroad, in the best medical journals overseas!"

We are willing to acknowledge the gap. Even domestic academic journals are not as good as the top international journals. We should admit that.

Therefore, in the editor-in-chief's view, publishing this article domestically was even a loss! It was a great opportunity for publicity. Achievements of this level are truly rare domestically, and there are none internationally. Not taking this opportunity to publish it abroad and let the world see our development would be a real waste of this achievement and the hard work of our comrades.

These days, unlike decades later when academic papers are everywhere, it's incredibly difficult to produce a groundbreaking achievement that has significant practical value.

"Hey, is that what you mean? You were speaking in such a breathy way, it startled me."

"You're stupid. What other possibility is there for taking down this kind of achievement if they just want to publish it abroad? Really."

"Fine, I can't argue with you, okay?"

The editor happily replied to the author, saying that since the article was going to be published, it was best to inform the author first.

Meanwhile, the editor-in-chief took the keyboard, created a copy, and began revising the article, personally handling the revisions.

Actually, there's nothing else wrong with it. He just wanted to delete and revise the outlook section at the end of the article. The application directions of non-specific and specific reagents are fine, that's normal discussion. But the idea that the next step is to expand into quantitative analysis is not acceptable. The previous part is already sufficient. This part is a bit too much.

"Chief Engineer Gao, the Fe3O4 nanopowder has been successfully prepared, with a particle size of 15-40 nm." Liu Rongguo was very excited. He didn't know what this stuff was used for, but at least he knew that this level of Fe3O4 powder had never existed before.

The creation of something that never existed before in his hands has enough meaning for him; what he does with it is irrelevant.

Life will find its source, and so will materials. With Chief Engineer Gao around, things have probably already been arranged clearly.

Gao Zhendong took the test report and looked it over carefully, nodding repeatedly: "Hmm, not bad, not bad, very fast, and the product meets the requirements. Here's what you'll do: report this to the ministry, which is like setting up a research project for you, but you won't be able to publish any articles, you know what I mean, hahaha."

This thing is very fast, which is not unexpected for Gao Zhendong. It is based on a mature process. As long as the raw materials are of good quality, the final result will be fine. Moreover, it is extremely fast.

Most physical and chemical experiments or production processes are not like farming; they are quick. There are not many that require a long time to complete, like those involving mercury cadmium telluride crystals.

Comrade Xiao Liu also put a lot of effort into this. It's well-deserved that this project was directly assigned to him and his team members. As for myself, it's a piece of cake.

Hearing his words, Liu Rongguo was a hundred times happier than him. What is an article? Can you eat it?
More than 90% of the achievements from the Third Factory cannot be published in papers. It's not that they are not qualified, but that they cannot be published, so whether or not they are published is of no concern to him. Chief Engineer Gao told him to report the achievements to the ministry in order to solve this problem. The good thing about following Chief Engineer Gao is that not only can you produce achievements, but you can also produce achievements that will make you famous.

Gao Zhendong took out another document: "Next, you'll be working on this. It's a bit more special than Fe3O4, but overall it's similar. The difficulty will gradually increase, taking you to the next level! Oh, and remember to go to the internal security office to complete the necessary paperwork."

What he presented was the preparation process for hexagonal flake-shaped barium ferrite powder.

This substance can be used in both high-density magnetic recording media and stealth coatings. It is one of the main components of early and mid-stage stealth coatings. When combined with Fe3O4, it has excellent wave absorption properties.

Compared to other microwave absorbing materials, which are theoretically very useful but difficult to prepare and process, this composite microwave absorbing material is relatively easy to make and has good performance.

However, this is only a component of the wave-absorbing material, not the final product. Otherwise, Gao Zhendong would not have handed it over to Liu Rongguo so easily; it was just a matter of completing some paperwork.

Liu Rongguo took the materials and was immediately stunned.

This material looks impressive just by looking at its chemical formula; compared to Fe3O4, its name sounds much more imposing!

BaFe12O19! ! ! ! !

Regardless of what it is, the name alone sounds extraordinary.

Just like alum sounds quite ordinary, potassium aluminum sulfate dodecahydrate sounds extraordinary.

"Chief Engineer Gao, this thing looks really complicated." Liu Rongguo, who already had a good understanding of chemistry, knew that the structure of a compound was actually more complex than its chemical formula appeared.

"Don't be afraid. Just keep doing it step by step, and it will appear naturally. I've studied it repeatedly, and there won't be any problems," Gao Zhendong said with a smile.

Liu Rongguo then remembered what he was worried about. This was a process personally proposed by Chief Engineer Gao. It wasn't that there wouldn't be any problems, but generally speaking, there wouldn't be any major issues. The success rate was extremely high, and there weren't many things that needed to be modified.

Having worked with Gao Zhendong for so long, he still has this confidence.

"Okay, I'll get right on it!" Liu Rongguo, carrying the materials, went off with great enthusiasm to prepare for the start of work.

Although Chief Engineer Gao has laid the groundwork and cleared away most of the obstacles on the road, there are still many specific tasks that need to be implemented one by one.

He was busy with paperwork, applications, coordinating equipment and materials with the Department of Applied Chemistry, and so on. But for Liu Rongguo, the busier he was, the happier he was.

The Applied Chemistry Department still consists of those two mentors and apprentices in the field of ferrites.

“Master, this 17th Ministry of Machinery is a bit strange. Is it obsessed with ferromagnetic materials? This time it’s FeCl3 again, but there are also urea, BaCl2, CaCl2… What are they trying to do?” The young comrade said to his master while preparing the reagents.

These reagents are not difficult to find, but high-purity ones are a different story; you really have to ask the Applied Chemistry Department for them.

“I guess it’s barium ferrite… but what kind of barium ferrite it is is hard to say. It seems that the 17th Ministry of Machinery Industry has a project closely related to ferrites, and it’s progressing very quickly!” his master pondered.

He spoke calmly, but his heart was in turmoil. It wasn't a raging storm, but at least the wind was calm, the waves were still, and his mind was uneasy.

Wow, that's fast!
This barium ferrite is definitely closely related to the previous Fe3O4 ferrite. After all, there are requirements for the preparation of the same type of material in a short period of time, and it is absolutely impossible to say that there is no connection between the two.

But the comrades are moving way too fast. How long has it been since they last requested materials? This speed doesn't seem like research at all. It's more like the research is already complete, and they're moving directly into production. The process is already extremely mature, so the progress is as fast as mass production.

But calling it mass production doesn't seem quite right. Although the amount of reagents they requested was not small, it wasn't much compared to the amount needed for mass production. Although the "mass production" of ferrite wasn't very large either, the amount requested last time had absolutely nothing to do with mass production.

Furthermore, if it's for mass production, then they should continue to use Fe3O4 as a raw material, rather than switching to barium ferrite. This indicates that the previous research was complete, and they've already shifted their focus to barium ferrite. This shows they're moving quickly!
Are there comrades working on ferrites in the 17th Ministry of Machine Building? And they're highly skilled!

It seems that this person or group of people wants to develop a series of ferrites, but it's unclear how far they will go or which ferrites they will be interested in.

The comrades in the Applied Chemistry Department who were working on ferrites pondered for a moment, but the work of preparing materials and reagents did not stop.

The northern part of the Bohai Sea is not particularly cold compared to the inland areas in winter. The sea is a huge heat-container, and it releases the heat stored in summer during the cold winter, which somewhat compensates for the temperature drop.

Even so, on a ship in the northern part of the Bohai Sea, the comrades were still freezing cold. The air temperature and the perceived temperature were two different things, and the sea breeze was completely unrelated to the warm and gentle feeling described in the ballad.

It swished and scraped like a knife, causing a sharp pain.

The ship has completed its work and is on its way back to port. The comrades who have been setting off firecrackers all day are a little tired, but they don't care that they haven't arrived at the port yet. They are working hard on the ship to process the data from this exploration.

"The new earthquake detector is much better than the old one; it can detect a much wider range and has a higher resolution."

Setting off firecrackers involves using explosives to generate shock waves, which are then used by earthquake detectors.

The comrades were in high spirits as they watched the earthquake detector images slowly unfold on the computer screen.

This is an exploration vessel equipped with the latest seismic detectors, searching for oil in the Bohai Sea.

As is well known, my country's largest oil field is located in Northeast China, and the geological structure of the Bohai Sea is consistent with that of Northeast China. In fact, the Bohai Sea can be considered a rather low-lying landmass, since the seabed elevation, even at its deepest point, is higher than that of the Flaming Mountains region in Xinjiang. This means that if there are oil fields in Northeast China, there may also be oil fields in the Bohai Sea.

Moreover, precisely because the Boreal Sea is shallow enough, it is considered one of the most important areas for offshore oil exploration, just like some of the shallow waters to the south. Our current extraction technology is barely capable of even extracting oil from the depths of the Boreal Sea.

Fun fact: my country's first modern offshore oil field went into production in 85.

According to the exploration plan, exploration will proceed from north to south. The north is close to the northeast, and can receive good support in terms of technology, resources, and personnel. Once the exploration in the north is completed and the experience and technology are in place, then we can move south.

This ship had just completed exploration of the northern part of the area, primarily using the latest seismic detectors. These seismic detectors were at the technological level of Gao Zhendong's previous life, around the 8s and 90s, and their technical specifications were more than sufficient for use in a newly developed area that had not yet been cultivated.

Nothing has been discovered in the new area, and the undiscovered shallow oil and gas layers are excellent exploration targets for this seismic detection system.

Although the exploration in the previous period yielded no results, the comrades were not discouraged. They were returning to their home port for resupply. This home port was actually located to their south, on the tip of the northern part of the Bohai Strait.

"It's okay if we haven't found anything yet. This is just the beginning. Comrades, have confidence. Once we've resupplyed, let's continue working. We'll find something eventually. The experts from the Institute of Geological Resources have analyzed the area and believe there's a high probability of oil and gas in this area. It's just a matter of sooner or later, and how much!"

The seismic detector data processing and imaging system developed by the colleagues at the Institute of Geological Resources has advanced functions. It can directly draw a rough image of the underground surface on a color display based on the seismic detector data.

However, the more advanced the function, the slower the speed. For this early C6108 machine, the calculation was a bit difficult and the speed was a bit slow.

It's not that we don't have faster machines, it's just that our colleagues are reluctant to install such fast machines in this environment, so we only installed one C6108.

The images appeared faster than the sun set; as the last rays of sunlight disappeared from the horizon, the world was plunged into darkness.

At this moment, in this data processing room, apart from the slightly dim incandescent lights, there were only computer color monitors. Coincidentally, the background color of this picture was also slightly yellow.

As the images gradually appeared, one of the comrades suddenly became somewhat excited.

"Look, here, here, the image seems a little different."

His finger pointed to a line that had just emerged, which was somewhat different from the surrounding ones.

The other comrades gathered around and observed carefully.

The lines are very narrow, and because the area is so small, even the colors are somewhat indistinguishable. They are also difficult to distinguish from the colors and densities marked on the legend.

"Perhaps it's due to geological folds. The new instrument has a much wider dynamic range, and the images are much clearer than before, with more detail." The leader lowered the expectations of his comrades, afraid of disappointing them.

Since it's only just started operating, there haven't been many round trips back to port yet, so its luck probably won't be that good. This ship uses 2D seismic surveying, which can only detect in a linear fashion, generating a continuous profile, so the actual area of ​​the seabed being surveyed is not very large.

As a leader, you not only have to pay attention to technology, resources, and coordination, but also to the emotions and psychology of your colleagues, which is quite tiring.

The comrades didn't say anything, just silently drank hot water to ward off the cold, quietly waiting for the images to continue to be generated piece by piece. The images were generated continuously along the direction the ship was moving. If Gao Zhendong could see it, he would probably recognize the feel of an old side-scrolling action game on an emulator, as they were all generated in the same way.

The progress of the image is like the download progress bar when gamers install a game—very slow, and it seems even slower when you're anxious.

"No, no, look, the color is much clearer now! Judging from the density, it seems to be within the density range of oil!" Seismic detectors rely on the changes in seismic wave velocity caused by density differences in different structures to detect underground structures, so they can naturally process the density. However, accuracy is another matter, and this new machine happens to be much more accurate than the previous ones.

Comrades looked at the monitor, and at that moment, a small patch of low-density shadow began to emerge from the lower right side of the screen, gradually becoming clearer.

The color of this low-density shadow is very similar to the color of the oil density range marked on the monitor.

The comrades got excited and swarmed around.

"Hurry up, hurry up, this broken machine, why is it so slow..." one comrade couldn't help but complain.

The team leader smacked him on the neck: "Dream on! This kind of thing wouldn't even be able to fit on a regular ship abroad! And you look down on it, calling it shoddy machinery? Huh?"

If this C6108 machine were placed overseas, there really wouldn't be many exploration vessels that could afford to carry it.

"I was wrong, I was wrong, Captain, I was just too impatient," the complaining comrade laughed.

"You can't say that just because you're impatient. The comrades who work with computers have put in so much effort to get these computers installed on our basic ships. Don't say things like that again." The team leader gave a brief instruction, then turned to himself and stared intently at the monitor screen.

Please, it can't be a color difference; it absolutely must be the density of oil...

Due to technical limitations, the colors on modern color monitors are somewhat distorted at the edges of the screen, which is why people are hesitant to confirm this.

The comrades gathered around the small 14-inch monitor, waiting.

After a long while, a cheer erupted from the crowd.

"It's the density range of oil! It's the density of oil!"

I wouldn't dare call it petroleum, but at least the density range is similar.

On the monitor, the low-density shadow that had already reached about one-third of the way across the screen remained continuous, and its color was exactly the same as the density and color of oil. The tail of the low-density shadow was still hidden on the right side of the monitor, stretching endlessly.
