Metal nanocloud, this term doesn't seem to be new, but what it means is really not clear to anyone. Copy this address to view %77%77%77%2e%62%69%71%69%2e%6d%65

At least when Lin Xiao and Han Ya heard it, they both had some unclear feelings, and they didn't know what this was.

"Well, I think you should always know about the concept of nano, right?" The scientist in charge of the lab scratched his head, not knowing for a moment how to explain the problem to them.

"Of course we know that." Lin Xiao nodded and replied, "Nanotechnology itself is just a unit of length, but nanotechnology is different, it is a general term for a technology that studies the properties of matter in a microscopic state. ”

"Yes, what Lin Ji said is exact." The scientist nodded and replied, "What we are dealing with now is such a nanotechnology, but its carrier is a bit special and does not belong to the earth element. ”

Nanotechnology, also known as nanotechnology, is a technique that studies the properties and applications of materials with structures in the range of 1 nanometer to 100 nanometers.

Since the invention of the scanning tunneling microscope in 1981, a door to 0 was born. The length of 1 to 100 nanometers is the study of the molecular world, and its ultimate goal is to construct products with specific functions directly from atoms or molecules.

Therefore, nanotechnology is actually a technology that uses a single atom and molecule to range matter.

From the research so far, there are three concepts about nanotechnology.

The first is the molecular nanotechnology proposed by the American scientist Dr. Dr. Drexler in 1986 in "The Instrument of Creation", according to this concept, the instrument that combines molecules can be put into practical use, so that all kinds of molecules can be arbitrarily combined, and any kind of molecular structure can be manufactured.

However, there has not yet been significant progress in nanotechnology for this concept.

The second concept positions nanotechnology as the limit of microfabrication technology, that is, the technology that artificially forms nano-sized structures through nano-precision processing, and this nano-scale processing technology also makes the miniaturization of semiconductors reach the limit.

Even if the existing technology is developed, theoretically it will eventually reach the limit, because if the wire width of the circuit is gradually reduced, the insulating film that makes up the circuit will become extremely thin, and the insulation effect will be destroyed.

In addition, there are problems such as heat generation and shaking, and in order to solve these problems, researchers are working on new types of nanotechnology.

The third concept is proposed from the perspective of biology, originally, organisms have nanoscale structures in cells and biological membranes, and the development of DNA molecular computing and cell biocomputing has become an important part of nanobiotechnology.

"The current research and application of nanotechnology is mainly in materials and preparation, microelectronics and computing technology, medicine and health, aerospace and aviation, environment and energy, biotechnology and agricultural products." The scientist told Lin Xiao and Han Ya, "Devices made of nanomaterials are lighter, harder, have a longer lifespan, lower maintenance costs, and are more convenient to design." The use of nanomaterials can also make materials with specific properties or materials that do not exist in nature, and make biomaterials and biomimetic materials. ”

Lin Xiao nodded, he still had this bit of common sense.

"For example, the strength and hardness of materials sintered with nano-scale metal powder are much higher than those of the original metal, and the nano-metal actually changes from a conductor to an insulator." The scientist continued, "Ordinary ceramics have low strength and are brittle, but ceramics made from nano-sized micronized sintering are not only strong but also have good toughness. For example, the melting point of gold is 1064C, but the melting point of 10nm gold powder is reduced to 940C, and the melting point of 1nm gold powder is reduced to 830C, so the sintering temperature can be greatly reduced. The sintering temperature of nano-ceramics is also much lower than that of the original ceramics, and the nano-scale catalyst is added to gasoline to improve the efficiency of internal combustion, and the addition of solid fuel can speed up the rocket. The drug is made of nano powder, which can be injected into the blood vessels and smoothly enter the microvessels. ”

Han Ya and Lin Xiao were quite interested when they heard this, there were some things that they really didn't know before, for example, the melting point of gold at the nanometer level had actually changed, which was very strange, but after thinking about it carefully, they felt that it was understandable.

"There is another important topic, which is nanobots." The scientist said, "Nanorobots are designed prototypes based on biological principles at the molecular level, and functional molecular devices that can operate in nanospace, also known as molecular robots, and the research and development of nanorobots has become a frontier hotspot in today's science and technology." ”

Lin Xiao listened very carefully, in fact, since ten years ago, many countries have formulated relevant strategies or plans, invested heavily in seizing the strategic highland of nanorobots, a new technology, nanorobots have a wide range of potential uses, especially important is to be used in the medical and military fields.

The emergence of every new technology seems to contain infinite possibilities.

Or it won't be long before the magic nanorobots that are only the size of molecules will continue to enter the daily life of human beings, and by the middle of the 21st century, nanorobots will completely change the labor and lifestyle of human beings.

"Of course, nanotechnology is not only beneficial, on the contrary, its emergence has also brought great hidden dangers to human safety." "For example, there are four ways for nanoparticles to enter the body: inhalation, swallowing, absorption from the skin, or intentional injection during medical procedures. Once in the human body, they are highly mobile, and in some cases, they are even able to cross the blood-brain barrier. ”

For the present, the behavior of nanoparticles in organs is still a big topic that needs to be studied.

Basically, the behavior of nanoparticles depends on their size, shape, and interaction activity with surrounding tissues.

They can cause an overload of bacteriophage cells (cells that swallow and destroy foreign substances), triggering a defensive fever and lowering the body's immunity.

They may also accumulate in organs because they are unable to degrade or degrade slowly, and there is a potential danger of reacting with some biological processes in the human body, due to the large surface area, the nanoparticles exposed to tissues and liquids will immediately adsorb the macromolecules they encounter, which can affect the modulation of enzymes and other proteins, for example.

"It's a big problem." After hearing this, Lin Xiao naturally knew more about this, and couldn't help frowning.

If nothing else, just talking about a problem that breaks through the blood-brain barrier can bring about both beneficial and unfavorable effects.

Because of the blood-brain barrier, basically no drug can break through this barrier and directly enter the brain, so the problem of the brain is basically that the medicine stone is ineffective, and the operation can only act on the lesion physically, and cannot be slowly recuperated by drugs.

But if you break the restriction of this barrier, then it means that some drugs can enter the brain, and some brain diseases can be solved through drugs, which is of course a good thing.

But the problem is that some negative factors can also enter the human brain, or will pose a serious threat to the safety of the brain, or even directly destroy the brain operation system, resulting in human brain death, which is not a random speculation, but has more than nine percent of the possibility.

And through the explanation of the experts of the secret service, Lin Xiao also figured out one point, that is, the metal pigeon egg he obtained this time seemed to be the nanoparticles of some unknown element, and this thing seemed to have produced many abnormalities, which was enough to shock the scientists.

"What about this...... What kind of thing is it? Han Ya looked at the cloud-like object in the vacuum chamber and finally asked.

"According to our preliminary observations, although a single individual does not form consciousness, a certain number of individuals combine to produce a function similar to that of biological intelligence." "In other words, this thing can already do something very special with a power similar to instinct." ”

"Sizzle......" When Lin Xiao and Han Ya heard this, they couldn't help but gasp.

Think about it, what could be more astonishing than this discovery?

Not only have unknown metal elements appeared, but this thing seems to have existed as nanoparticles from the beginning, and what is even more terrifying is that they can be freely combined to form a semi-psychic existence, which sounds scary, not to mention that the real thing has been seen now.

"What is this, Transformers combined?" At this time, Lin Xiao looked at the cloud-like objects in the vacuum chamber and couldn't help muttering to himself.

I saw that in the vacuum chamber, these cloud-like objects had begun to slowly condense, just like when Lin Xiao used the law space to condense them into a metal pigeon egg, but this process was relatively slow.

But in any case, this thing is really condensing on its own.

"Could it be that this thing still has the function of memory metal?" After Lin Xiao watched it for a long time, he suddenly raised such a question.

When the scientists inside heard this, they couldn't help but become even more excited, "Lin Ji is right, it's very possible!" yes, why didn't we think about this before? It seems that the research of this project is even more groundbreaking! ”

In the speechlessness of Lin Xiao and Han Ya, the scientists suddenly became busy again, tossing those instruments and equipment, bombarding the gradually forming nanometal cloud again, and then bringing in various particle beams to bombard them.

All in all, how can you toss, just toss, all kinds of means have been used.

Lin Xiao looked at the things in the vacuum room, and always felt that there was a very inappropriate feeling in his heart, as if he had ignored something.

At that time, when I was flying, it seemed that I missed something?
