Dahan Technology Empire

The first and biggest problem facing Imperial scientists at present is to create materials that can be used in warp engines, and to build materials from an atomic perspective.

The development of science and technology has made it possible to synthesize materials at the atomic scale, such as atomic clusters, cluster materials, linear chains, multilayer heterostructures, ultrathin films, etc. These materials are characterized by low dimensionality and symmetry reduced, the geometric features are significant.

But it is only possible. When it is actually operated, it is difficult to truly create the materials you need from the perspective of atoms. The unit of atoms is really too small. At most, the current science and technology can only It can be done on the nanometer scale, and atoms are much smaller than nanometers.

First of all, we must first understand their size. Nano is abbreviated as nano in English. Nano is a kind of length unit. 1 nanometer is one billionth of a meter, recorded as nm.

1 nanometer is the length of 10 hydrogen atoms lined up next to each other! Because each type of atom has a different diameter, 1 nanometer might be the length of an arrangement of dozens of atoms of other elements.

20 nanometers is about one third of a hair strand!

And what we usually call nanotechnology refers to the technology of studying the special phenomena and special functions of matter in the nanoscale (100 nanometers to 0.1 nanometers), and creating new materials by directly manipulating and arranging atoms and molecules. !

The emergence of nanotechnology first benefited from the invention of the scanning tunneling microscope (stm), which can magnify ten million times. The invention of the scanning tunneling microscope enables scientists to observe the microscopic world at a nanometer angle.

Since the early 1990s, nanotechnology has developed rapidly, and new disciplines such as nanoelectronics, nanomaterials, nanomechanics, nanobiology, etc. are constantly emerging. Nanotechnology is the future of the language of scientists to change human beings. One of the 9 great sciences of history!

In fact, although today's scientists can observe the information at the atomic level through stm technology, and have a certain impact on the atomic arrangement.

For example, in April 1990, two scientists from IBM in the United States were inspired by the motion of the probe and the xenon atoms when they observed the xenon atoms on the metal nickel surface with stm, and tried to use the stm tip to move the xenon atoms adsorbed on the metal nickel. Arrange 35 xenon atoms on the surface of nickel to form an ibm structure with a height of 5 atoms!

Scientists from the Chinese Academy of Sciences also used nanotechnology to draw the world's smallest map of China by relocating carbon atoms on the surface of graphite, which is less than 10 nanometers in size!

Since then, scientists have enjoyed moving various atoms to form various patterns, silicon atoms, sulfur atoms, iron atoms, carbon monoxide molecules, iron-based molecules...

From here, we can know that what scientists can currently achieve is to move some atoms a little and place various patterns on the surface of the object. Large-scale, rapid creation of new materials at the atomic level.

But even so, it is only possible to simply move some atoms and arrange some atomic structures on the surface. Scientists have also produced various complex nanomaterials today, and artificially artificially manipulate the structure of copper atoms on the surface of copper. Arrangement can also increase the strength of copper by 5 times!

We all know that diamond is diamond, graphite, and coke. The atoms they consist of are actually the same, that is, carbon atoms! However, the properties of these materials are very different. In terms of hardness alone, diamond is the hardest material in nature, while the hardness of graphite and coke is very low.

The reason for this difference is the structure of carbon atoms. In the atomic structure of diamond, each carbon atom forms a covalent bond with another 4 carbon atoms with a sp3 hybrid orbital to form a regular tetrahedron. Due to the strong c-c bond in diamond, the hardness of diamond is large,

The melting point is extremely high; and because all valence electrons are confined to the covalent bond region, there are no free electrons, so diamond does not conduct electricity.

In the graphite structure, carbon atoms in the same layer are sp2 hybridized to form covalent bonds, and each carbon atom is connected to three other atoms by three covalent bonds. Six carbon atoms form a regular six-connected ring on the same plane, stretching into a lamellar structure.

The bond lengths of the c-c bonds here are all 142pm, which just belongs to the bond length range of atomic crystals, so for the same layer, it is an atomic crystal. Carbon atoms in the same plane each have one p orbital left, and they overlap each other. Electrons are relatively free, which is equivalent to free electrons in metals, so graphite can conduct heat and conduct electricity, which is the characteristic of metal crystals.

It is simple and easy to understand that the carbon atom structure of diamond is three-dimensional, and all carbon atoms directly form a regular tetrahedron with each other, which is a three-dimensional structure!

The structure of graphite is that the carbon atoms form a regular hexagonal ring on the same plane, forming a lamellar structure, that is, a layer of carbon atoms, but there is no connection between the carbon atoms between the layers. It's a flat structure!

A three-dimensional regular tetrahedron structure and a planar regular hexagonal structure cause the material properties between diamond and graphite to be vastly different, and their value is also different from cloud and mud! The price of diamond is calculated by carat, and the price of graphite is calculated by ton. The difference in value is more than billions of times!

The Empire wants to develop materials for warp engines, that is, to build materials from the perspective of atomic three-dimensional, and turn decay into magic! For example, if the atomic angle of iron is changed into a three-dimensional structure of a regular tetrahedron like that of diamond, what kind of material will be obtained?

The person in charge of the research materials is Mo Qingming, the chief scientist of the Imperial Academy of Materials Science and the head of the Academy of Materials Science in Qingquan Science and Technology Era!

At this time, Mo Qingming was also in his 50s. Because of the reason of cultivating Yuan Li all the year round, he looked very young in his early 50s at this time, and there was no difference from his 20s, but he was a scientist of his age. , according to the standards of the earth, it is the peak moment of a scientist's life!

Before cultivating Yuan Li, the average life expectancy of a person is about 80 years old. The first 30 years are basically in the learning stage, and then it will take more than ten years to explore and accumulate on the road of science, to more than 40 years. The age of about 50 years old is the peak stage.

With experience, accumulation, and foundation, people's energy can still be very abundant, the brain is quick and active, the body is good, and they can fight for a long time. Once this age is passed, whether it is a good body or a brain, it will appear. A large landslide, at that time, the value of scientists will be greatly shrunk!

This is also the reason why many people complain about Yang Zhenning now. The country has cultivated you for the past few decades. Fortunately, you have worked for Americans for decades at the most brilliant and effective age. When you are old, your brain thinking, The body is dead, and I ran back to all kinds of shit!

The scientists of the empire have been practicing Yuanli since the Qingquan technology period, and the younger generation went to the Yuanli Warrior Hall to receive Yuanli training since childhood, so everyone who looks like a weak scholar is actually all of them. It is a master of Yuanli, a humanoid nuclear bomb!

Of course, their value is countless times higher than that of nuclear bombs. The cultivation of Yuanli makes these scientists have a long lifespan, and the time they can use for scientific research is greatly increased. At the same time, their brains are developed by Yuanli. Horror, amazing learning ability, very active thinking!

On the one hand, it shortens the time for scientific study and accumulation. Of course, with the development of science and technology, a scientist needs to learn more and more things; on the other hand, it can greatly extend the golden period of a scientist.

Scientists who have not cultivated Yuan Li may only have a golden period of ten years, but scientists who have cultivated Yuan Li have a very long lifespan and a very healthy body. Their golden period can be hundreds of years, thousands of years...

Mo Qingming, who is in his 50s, is officially at the peak of his life. At this time, the belt is hosting a materials science conference, and all the great scientists of the empire research materials are called together.

The empire was founded on science and technology, and the emphasis on science and technology is unprecedented. The status of scientists is also very high. Basically, the nobles are all scientists and engineers. Very few politicians can obtain the title of nobility unless they have made some special contributions. Or an official to the level of a cabinet minister, otherwise the best way to get the title of aristocrat is to become a scientist or engineer!

Materials science is a very important branch of science. There are many people who choose this subject. After decades of development in the empire, a large number of talented scientists have emerged. Among them, there are also many scientists in materials science, and many of them are young Light is already a genius figure of a 3rd-level scientist.

Mo Qingming looked at the many young faces below, uh, of course, many old people looked very young because of cultivating Yuan Li, and couldn't help sighing in his heart: Nima, these young people are too good, myself The position of the machine is shaking, and if you don’t work hard to develop the materials for making the warp drive, no one will mix with those old guys!”

The many young faces below naturally do not know what the great scientist on the stage is thinking at this time, and they are all quietly waiting for him to speak. In the field of materials, Mo Qingming is a well-deserved giant. It can be said that he and I are present here. It was brought out by scientists from the Qingquan Institute of Technology and Materials.

Not much nonsense, the empire wants to enter the sea of ​​​​the universe, and the warp engine is indispensable, and the biggest problem of the warp engine at present is the material problem. This is the moment when we show our wisdom!
