Chapter 112: Terahertz

Zhu Cheng announced about ion salts! Scandal about DDT!

And it's self-media promotion! Whether it's the Battle Shield or the Wisdom Eye, the computer has these contents, and the detailed data tells everyone! What is called capital operation? Pen? Interesting? Pavilion wWw. biquge。 infoWhat is public opinion guidance! What is exploitation!

Since the capitalists control public opinion and the media, the capitalists have never panicked anymore, they have done all the bad things, pointing the deer as the horse! But no one dared to mention any of this. Today, this weapon has finally suddenly failed! How can the capitalists not be frightened!

The core of the anti-cancer detection and treatment instrument, the "miracle bullet", was also announced by Zhu Cheng.

This FDA-suppressed drug has finally been known by everyone, in fact, there has long been a drug that can relieve the pain of cancer patients, although it cannot be cured, but at least there is a new possibility in symptom relief and the spread of cancerous cells.

Zhu Cheng, who lifted the lid, quietly waited for the change, can this information kill the capitalists with a stick? It's simply impossible.

Moreover, the data leak has been known to the capitalists, and both Soros and Kerim are insiders. They were prepared.

It doesn't matter what kind of dirt they have inside, or what kind of transactions they have. But the muzzle is unanimously outward! Because their interests coincide!

Demonstrations took place on the streets of various countries, demanding an explanation. From the Internet to the people, they are full of dissatisfaction with shady scenes and the thirst for hidden truths, and they chant in the hope of getting a positive answer.

Fooling the people and lowering the wisdom of the people is something that the capitalists have always been happy about, and countless people do not know the power of DDT and the significance of DDT to the Third World! It is not clear what a huge chain of interests is behind this. Therefore, the truth that the people crave is told by the initiators, the capitalists. How ridiculous.

The "miracle bullet" has finally come out of the dusty FDA archives and into the world.

The capitalists have long known about the leaked materials from the underground laboratory of Google X, and they have long been psychologically prepared, and they have long had various scapegoats. And the answer that the capitalists give to the people is that it is caused by the corruption of an FDA official. The officer was fined and sentenced to life imprisonment.

Naturally, this result did not satisfy everyone, and they spoke out and continued to delve into the issue! They demanded the truth and demanded criticism, and these voices did not make the capitalists sit on pins and needles, this matter is so old that it can no longer be traced, all kinds of information are lost, and the parties concerned die.

Within a few days, the whole world slowly quieted down, and many things had results if they didn't fight. Just like Martin Luther King's cry, it can only wake up a few.

At this time, the domestic situation was calm, whether it was the addition of calcium and magnesium ions to sea salt, the DDT tragedy, or the FDA's private collection of anti-cancer drugs, it was just a topic of conversation after dinner, and they were more concerned about when Cree's medical warehouse would be popularized in their cities.

In the back garden of Gemini, mechanical life is roaring, Daystar is regulating, and medical warehouses are constantly producing, then packed and shipped to all parts of the country.

Zhu Cheng rested in the lounge, whether it was production, packaging, loading and unloading, it was completed by Daystar's Ron and self-driving cars, all of which were in order, and naturally he didn't need to worry much.

He has already started to prepare for the upgrade of the Black Technology Library, and he needs to recuperate.

Now there are only 100 first-class books in Cree's library, and these books are all memorized by Zhu Cheng. He was just reviewing these knowledge points to prevent them from being forgotten during the exam. A good state can make the test score more ideal. He approaches his exams with perfection.

As a top student, he naturally knows how to adjust to make his spirit better, and it is useless to study frantically before the exam. A good mental state can make him play better.

After a leisurely nap, he woke up and found a message from Daystar.

"Sir, in the private laboratory on the top floor of the Gemini Building, the hydrothermally grown nonlinear optical crystals have been grown. Your plan is ready to be implemented. ”

He was pleasantly surprised, this nonlinear optical crystal is the cornerstone of many technologies, it can be said that without this technology, it is impossible to open a series of science and technology trees, just like the status of Shannon's information theory, Shannon, known as the "father of informatics", proposed in his 32-year-old master's thesis that all information in the world can be represented by 0 and 1.

Nonlinear optical crystals, which are the basis of lasers, like KBBF, can shorten the wavelength of the laser to achieve its purpose.

"I'll take a look."

Zhu Cheng got up, the living room was not extravagant, there was a desk by the window, and there were some papers on it, which was a set of data that he checked yesterday, about the changes in the specificity of human reinforcement, he was summarizing all the data of human reinforcement feedback.

Outside the window is countless greenery, and after more than a month, there are already some creatures nesting in the back garden of Gemini, and there are unknown birds outside the window. In the treetops, a few squirrels are stockpiling food for the winter. Chase and play among the treetops, holding food and frolicking.

It's late autumn, and the leaves are all over the ground. A few housekeeping robots sweep the fallen leaves on a forest path. Sasha's sweeping sound and crisp birdsong echoed in Zhu Cheng's ears.

The weather seems to be much better these days, but an autumn rain and a cold. The aftermath of the autumn tiger has gradually faded. The Winter Maiden is coming soon.

Zhu Cheng took his jetpack and flew towards the top floor of the Gemini Building, in the eyes of his science and engineering subjects, between two points, the shortest straight line is a deep-rooted obsession. So he didn't have time to observe how dazzling the autumn scenery was.

Nonlinear optical crystals are top projects in domestic scientific research, and many methods are used. But in the atmosphere, nonlinear optical crystals serve only one purpose, and that is terahertz waves.

Terahertz waves are known as the forgotten gems of mankind. Between microwave and infrared. Before it was officially named, it was called Far Infrared Ray, classifying her as infrared, and forgetting was a loss for humanity.

Teraherzes are also known as one of the top 10 technologies that will change the world in the 21st century.

The unique performance of terahertz has brought earth-shaking changes to the fields of communications, radar, electronic countermeasures, electromagnetic weapons, astronomy, medical imaging, non-destructive testing, and security inspection.

Its technical difficulty is that the generation source is unstable, and there is no highly sensitive detector.

In fact, the principle of teraherz is not complicated, and a high-intensity, short-wavelength laser will be hit on a metal polyethylene target, which will produce a stable terahertz wave and high-energy electron flow.

And this high-intensity, short-wavelength laser is the most difficult of the difficulties. Similar to KBBF nonlinear optical crystals, it is a high-tech frontier product sought after by various countries.

However, every breakthrough in nonlinear crystal technology is like buying a lottery ticket, touching it is a breakthrough, and if you can't touch it, you can only waste an experiment!

However, low-energy terahertz radiation sources have been popularized in some radars and laboratories, and the lack of high-energy terahertz radiation sources is an important bottleneck limiting the scientific development of terahertz technology.

At present, the international research on terahertz radiation based on laser-plasma interaction mainly focuses on the two-color laser-pumped air filament scheme, and the light intensity in the filament is clamped below 15-16 times w/cm2 of 10 due to the defocusing effect of the plasma on the laser.

The laser source is one thing, and on the other hand, damage to the optics is also a huge problem.

Plasma is capable of withstanding pumps of arbitrary light intensity, overcoming the severe damage to optical components found in traditional terahertz generation methods such as optical rectification.

His terahertz device is waiting for the advent of nonlinear crystals. The first target of terahertz, Zhu Cheng looked at the network communication that restricted the development of the network.

How fast is the internet? Nowadays, the vast majority of people are still using 10M, 100M, Gigabit Internet speed. And this network speed limits the speed of communication.

THZ technology can achieve a wireless transmission speed of 10Gb/s when used for communication! Of course, in the atmosphere, terahertz refraction, reflection, diffraction, and interference will lead to a decrease in this number, but it can also greatly improve the Internet speed of netizens!

Terahertz communications, especially satellite communications, do not need to consider the influence of the atmosphere because they are in outer space, in a state of approximate vacuum. This allows THZ communications to carry out highly secure satellite communications with extremely high bandwidths. Zhu Cheng is solving the problem of easy wear and tear of radiation sources and equipment components!

It is no exaggeration to say that with terahertz earth communication, it will be the real era of big data! When a movie is downloaded in a few seconds, the clarity of the video can also be greatly improved! At a time when the speed of communication is accelerating and the amount of information is growing rapidly, all kinds of communication-related technologies will make great progress!

Zhu Cheng took out the nonlinear optical single crystal from the aqueous solution, and then carefully observed the color under the tunnel microscope. Quite perfect!

His office is on the top floor, while the private laboratory is connected to an antenna on the roof of the Gemini Tower. Terahertz devices have been sitting there for a long time, waiting for the growth of nonlinear crystals.

Put the crystal into the terahertz device, turn on the power, and start softly. An invisible wave touched the city.

"Turn on LAN unlimited communication."

He lightly gave the order to the morning star, and the whole mountain city wisdom eye paused for a second to return to normal, and the communication chip they carried inside activated. The people of Yamashiro didn't know what was going on, they just stuck for a moment, and the person who was using the wisdom eye to make a phone suddenly found that the image of AR augmented reality was very clear! It's so clear that it's fake.

Cree was lying on the top of the three giants of communication, and the three giants endured. But Zhu Cheng suspected that they had a lot to do with the hijacking! And Zhu Cheng intends to quietly eliminate the three giants of communication, and he is not ready to tell them.

What is the concept of having wifi anytime and anywhere in the mountain city, and the speed of the network is up to 7G/s? Although it is only the LAN of the mountain city city.
