Master of time and space

"Yang Wentian, do you know why you children who are not yet 10 years old are allowed to experiment on nanomaterials?" Dong Qiuhong asked Yang Wentian when he operated a scanning tunneling microscope next to Zhibrain.

"I know, engage in scientific research, start with the doll!" Yang Wentian tilted his head and quickly came up with an answer that he thought was correct.

"You're only half right." Hearing Yang Wentiantong's answer with a confident tone in his voice, Dong Qiuhong's stern face showed a hint of a smile, "The reason for the other half is that children's hands are more sensitive than adults. Although instruments can be used to observe the microscopic world at the atomic level, it is not possible to use instruments to improve the sensitivity of human hand sensations when doing experiments. To know that the average person's finger gently swings, its range is more than one millimeter, and if you want to use human hands to control the lens probe to do a millionth of a millimeter, that is, 1 nanometer cutting action, it is difficult for one person in ten people to do it.

"Doesn't using the brain to control the problem solve, can it be so laborious?" Yang Wentian looked at the scanning tunneling microscope working under the command of Zhi Brain on the experimental table next to him, held his hands behind his head, and replied disapprovingly.

"As the old saying goes, manpower is sometimes poor. The intelligent brain is also a tool designed by the human brain, and it cannot perform actions that humans cannot even program out of nothing. Dong Qiuhong shook his head and said with deep meaning: "Most of the experimental data we use now are obtained by the unremitting efforts of predecessors. As contemporary researchers, we must make breakthroughs on the basis of our predecessors and achieve feats that have not been achieved by our predecessors, so that this life will not be in vain.

"The words of the tutor, the student is taught." Yang Wentian's thinking ability is amazing, and Dong Qiuhong's heartfelt words resonated with him, and he nodded cautiously and cautiously, with some enlightenment and cognition in his heart.

"Now let's move on to a circuit architecture experiment with nanomaterials." Dong Qiuhong is a practical scientist, Dao Li did not say much, gently patted Yang Wentian on the shoulder, signaled him to walk to the scanning tunneling microscope next to him that had completed the work instructions, and manually operated the microscope.

"See clearly, here is the undivided raw material, and here is the nanomaterial extracted by the segmentation." Dong Qiuhong manually adjusted the resolution of the scanning tunneling microscope, first using ordinary 100x magnification to observe the situation on the slide, and then gradually increasing the resolution. Through the image displayed on the screen of the brain, Yang Wentian saw that an insignificant corner of the graphite crystal particles on the slide was missing, and next to it was a pile of fragmented debris.

"Now I will use these graphite crystal materials with a diameter of 10 nanometers at a resolution of 100 nanometers and lay out two Chinese characters to demonstrate how to construct a nanoloop model." While prompting Yang Wentian to pay attention to the changes in the wisdom brain screen, Dong Qiuhong operated the scanning tunneling microscope.

"The instructor is right, it's not much different from playing puzzles with bricks." Yang Wentian looked at Dong Qiuhong's experimental demonstration on the Zhi Brain screen with interest. I saw the lens probe, adsorbing the 10-nanometer-sized graphite crystals one after another, and placing them one by one in the blank space of the slide. The two Chinese characters 'Huaxia' slowly appeared in front of Yang Wentian little by little, and Yang Wentian clapped his hands innocently and said.

"You don't have to applaud me, it's just for practice." Dong Qiuhong smiled again and shook his head, demonstrating for Yang Wentian how to carefully remove the slide from the operating platform container of the scanning tunneling microscope, and saved the nanomaterials obtained on the slide, and recorded the data of the experiment.

"Well, this time I will show you again, split and extract copper element nanomaterials with a diameter of 1 nanometer, and build a usable nanoconductive circuit based on the material." After resetting the two scanning tunneling microscopes with both hands, Dong Qiuhong rubbed his hands and began to prepare for the next experiment, "For excellent scientists, being able to manually make 1 nanometer materials is only a minimum requirement." Although it is convenient to use intelligent brain and machinery to automatically produce, as a scientist, you cannot rely too much on intelligent brain and machinery, and technological breakthroughs also need to rely on human brains and hands. The

steps of the second experiment are basically the same as those of the first experiment, except that this time Dong Qiuhong needs to manually cut and extract 1 nanometer instead of 10 nanometer copper nanomaterials. And after the copper nanomaterials were made this time, these materials were no longer used to put words, but were used to carefully construct nano-conductive circuits.

"Simply put, use these copper nanomaterials to build a miniature machine." The number of nanomaterials extracted this time is as high as a thousand, and Dong Qiuhong is preoccupied with the manipulation of the lens probe, such as an architect and a foundry, arranging and stacking these nanomaterials according to certain laws to gradually form a nanomodel like a circuit board.

"Look, this is a relatively basic nanoconductive circuit, now let's try to transfer some microcurrent to this nanoloop." Instructor Dong Qiuhong made some corrections to the nanoloop model, and then cooled and fixed it as necessary before proceeding to the next step of operation.

"The current is constantly flowing on this model, well, it seems to have produced some peculiar phenomena." Yang Wentian was attracted by the scene of the nanocircuit powering on the Zhibrain screen at this time, and shouted while watching.

"It's the conductive effect and the magnetic field effect, which is a simple application of copper nanomaterials." Dong Qiuhong stopped the operation at hand, and also looked up at the Zhi brain screen, patiently explaining to Yang Wentian.

"Now, let's enter the data records of this experiment into the brains of small factory equipment, and use small factories to produce a batch of practical powders of copper nanomaterials." Dong Qiuhong quickly operated a few times on the intellectual brain screen of the experimental bench, and the small factory in the laboratory began to work.

The mechanical equipment of the small factory, first a copper ingot, cut into small pieces with a cutting machine, and then crushed into granules with a metal pulverizer, and then transported these metal particles to the nanomaterial production equipment, the brain just now Dong Qiuhong's experimental data into the program that has been compiled, the nanomaterial production equipment will continue to make and extract copper metal particles for nanomaterials.

After about half an hour, a copper ingot turned into a pile of nanomaterial powder, and finally the factory's robotic arm took some samples and sent them to the outside test bench.

"These nano-copper powders can replace precious metal powders and prepare electronic slurries with superior performance for the manufacture of microelectronic devices to achieve the purpose of greatly reducing costs and improving performance." Dong Qiuhong looked at the sample in the box in his hand, nodded with slight satisfaction, and handed it to Yang Wentian, "You have to remember that even if it is the same size of nanomaterials, the nanocircuits they constitute can be diverse, and the nano primary application powder composed of each nanoloop has a slightly different function." Theoretically, the smaller the volume of nanomaterials, the fewer parts of nanomaterials, the more powerful the nanocircuit.

"Even when a material element can be divided into atomic levels and the atoms can be rearranged into an effective molecular structure, a new material form of the substance can be obtained." Seeing Yang Wentian turning the powder sample box containing copper nanomaterials, Dong Qiuhong explained to him the knowledge again: "For example, the carbon element we know, the same carbon molecules, because of the different arrangement of atoms, there are three substances on the earth: coal, diamond, and graphite."

"I can understand this, I once broke down various gemstones and synthesized them into a ruby." Don't look at Yang Wentian is young, but he has a lot of knowledge, the knowledge and skill points estimated by the 'Zhen' Trigram Intelligence Research Center are 513,800 points, compared to ordinary humans if they study at full capacity every day, children 300 points a day, adults 500 points a day, you can know that Yang Wentian has been learning at an adult speed in the past three years.

"As a scientist, you can't lie, how can different types of gemstones be synthesized into the same gemstone." For Yang Wentian's words, Dong Qiuhong was obviously stunned, which was beyond his knowledge, naturally did not believe Yang Wentian's words, and severely reprimanded Yang Wentian.

"Be attentive when doing experiments and think less about other things. Now you follow the experimental process just now, or try to make nanomaterials for carbon first. Dong Qiuhong pulled Yang Wentian to the experimental table, sat down on the chair of the scanning tunneling microscope, and asked him to do the experiment.
