Master of time and space

"Kong Fanxi, you first explain the relevant knowledge of the nano engine to Yang Wentian, and then let him understand the progress of the relevant research." Mentor Dong Qiuhong gestured to the eldest boy who was about nine years old, and pointed to Yang Wentian who was eating his mouth with his newly obtained candy, "What should others do, those engaged in scientific research must race against time, and it is shameful to waste time." Dong Qiuhong did not let Yang Wentian go to the dormitory to rest just because he came.

"In my opinion, the real vampire is your mentor." The seven-year-old boy who was trying to doze off while sitting stretched again, "I haven't slept for more than 10 hours to do research, and you're calling us like child labor."

"Revolution is not a one-day success, and scientific research is not a day-long success, so sleep less and work more while you are still young." Dong Qiuhong walked over to the sleepy boy and fanned a few cool fans towards his face with the sandalwood folding fan in his hand, "Classmate Wu Yaohan, you should be much more sober in this way, go and perform the nano-segmentation operation of conductive materials, maybe you can successfully segment a single nanomaterial below 0.45 nanometers in diameter by trying again." "

Call Peng Dayou to do it, I've been working all night, now it's my sleep time." Wu Yaohan, who did not lead the teacher's affection, waved his hand, and simply lay on the sofa in the lounge, bending his body and holding his head and falling asleep.

"Peng Dayou, then you will be in charge of the segmentation and collection of nanomaterials during the day today. Today, your goal is to have to segment conductive materials below 0.5 nanometers. Dong Qiuhong snorted, the sandalwood folding fan put away, snapped on the palm of his hand, turned to another seven-year-old boy who had been silent, and only cared about fiddling with a miniature energy fusion simulator with a large slap and drank twice.

"Mentor, although I also understand nanomaterial micromanipulation technology, my hands are a little slippery when I am nervous, and secondly, I am conducting an energy conversion comparison test on the nanomaterials obtained by Wu Yaohan last night." While saying that Peng Dayou also raised the miniature energy fusion simulator in his hand, "You also know that you can't stop after the test, otherwise last night's efforts will be in vain."

"How many times have I said that you should first find a way to solve the nanomaterials used for conducting electricity, and then engage in nanomaterial research on engine fuel." When Dong Qiuhong heard it, he was really angry this time, the sandalwood folding fan opened in a loud manner, and kept fanning himself to cool the breeze, "Even if a fusion nanomaterial with a higher energy value is found to improve the engine fuel, but there is no more effective and stable conductive nanomaterial to transmit energy, and improving the power performance of the engine can only be empty talk." You still don't deserve me as a mentor." Now Dong Qiuhong has realized that it is difficult to educate children, and it is even more difficult to educate genius children, most genius children have their own way of thinking, and they are more skeptical and even resistant to adults' words.

"Compared with conductive nanomaterials, explosive fusion nanomaterials are easier to obtain and easier to produce results." Peng Dayou said while glancing at Yang Wentian, who was still eating candy with his head down: "It just so happens that there is a new person joining today, mentor, you can let him try it."

"I can't help you." When it comes to achievements, Dong Qiuhong is not good to continue, long-term results are necessary, short-term results can not be ignored, after all, scientific research equipment is a monster that swallows gold, and scientific research is a black hole that devours capital.

"Yang Wentian, in the morning, you follow Kong Fanxi to learn about nanoengines, and in the afternoon I will teach you how to make nanomaterials, and master them freely in the evening." After thinking about it, Dong Qiuhong made new arrangements for Yang Wentian. Originally, he did not want to let Yang Wentian conduct practical research so quickly, but since the research group he led had leased the right to use nanomaterial production equipment from the Academy of Sciences for three months, vacant scientific research equipment was tantamount to throwing research funds into the sea. Moreover, the nanomaterials extracted by the nanomaterials made of nanomaterials are more valuable than precious metals, and if the research team wants to take care of its own profits and reduce its dependence on research funds, the research equipment cannot be stopped.

(Just like today's sociobiological culture of animal embryonic stem cells, a box of stem cells costs no more than 100 yuan, but it can be sold for 5,000 yuan.) If you don't master the relevant technology, you even ask the other party to sell it. Yang

Wentian did not know at this time that he had become Dong Qiuhong, known as Baixiaosheng, a new object of pressing, and was still praising the delicious candy that the other party gave him.

"Yang Wentian, may I ask which disciplines you are best at?" After accepting the instructor's instructions, Kong Fanxi, who looked more honest, took Yang Wentian to a learning machine, and both of them sat in the control chair for teaching.

"To be honest, I'm like a tutor, I don't have any subjects I'm particularly good at, I just know a little bit of everything." Be low-key, this is the teaching of Yang Wentian by the tutoring system of Sister Peony, Yang Wentian licked his lips, took the tissue handed to him by Kong Fanxi and wiped his hands, sat up straight and answered.

"If you can be as powerful as Mentor Dong Qiuhong, I will let you be the head of this research group." Kong Fanxi gives people the feeling of being like his name, it looks very ordinary, he is almost nine years old and is about to leave the children's group to transfer to the junior group, he has begun to grow taller, his appearance is very shy, his body is relatively solid, and he is a typical working-class seedling. Because he came from a family that was not very wealthy, he worked harder than most of the children in the workshop in order to continue his studies in the workshop, and the research points he obtained were the highest in the research group today, and Dong Qiuhong designated him as the group leader.

"Hehe, the head of this research group, it's better to leave it to you, I don't have that spare time." Yang Wentian came to the workshop with a playful attitude, and he was not yet old enough to have a desire for power.

"The tutor just arranged for you to operate the nanomaterial production equipment in the afternoon, I suggest you first review the knowledge about nanomaterials and the use of nanomaterial production equipment.

"It's good to review it, so as not to be scolded by the tutor in the afternoon." Yang Wentian finally corrected his attitude and shifted his mind from the candy to the learning machine.

"The nanometer (symbol nm) is a unit of length, originally called the nanometer, which is 10^-9 meters (billionths of a meter), that is, 10^-6 millimeters (1 millionth of a millimeter). Like centimeters, decimeters, and meters, are units of measurement for length. It is equivalent to 4 times the size of an atom, which is smaller than the length of a single bacterium. While displaying knowledge materials on the screen of the learning machine, Kong Fanxi explained to Yang Wentian, "Suppose a hair has a diameter of 0.05 mm, cut it radially into an average of 50,000 roots, and the thickness of each root is about one nanometer.

"The so-called nanotechnology refers to a technology that studies the laws and properties of motion within electrons, atoms and molecules in the scale of 0.1~100 nanometers." The screen on the learning machine constantly displays content, "A few or dozens of countable atoms or molecules isolated by matter at the nanoscale significantly exhibit many new properties, and the technology of using these properties to make devices with specific functions is called nanotechnology." "

Nanotechnology is a highly intersectional and comprehensive discipline, and the research content involves a wide range of modern science and technology." Kong Fanxi is worthy of being appointed as the leader of the research group, and he speaks clearly and in-depth at a young age, "This is a science that is easy to learn and difficult to refine.

"The extraction and manufacture of nanomaterials belongs to the category of material microprocessing technology." Kong Fanxi reached out and clicked on the screen of the learning machine, and a microscope-like object appeared on the screen, "This is a scanning tunneling microscope, which can help us observe atomic-level images of matter that we usually can't see with the naked eye." "The scientific attitude is serious, and Kong Fanxi's appearance when he speaks is quite a bit of a mentor's temperament.

"It serves as a scanning probe microscopy tool, and scanning tunneling microscopy allows scientists to observe and locate individual atoms." Kong Fanxi switched the image again, and a microscopic video picture of the atomic level of the substance appeared on the screen, "According to different substances, in different low temperature environments, the probe tip of the tool can be used to precisely manipulate molecules and even atoms." Therefore, scanning tunneling microscopes are both important measuring and processing tools.

"I like toys like this, why don't we go play with them now." Looking at the video picture, the probe tip deftly divided an iron metal particle into metal materials smaller than 10 nanometers, and then arranged these nanomaterials on a metal plate into the word "Huaxia", Yang Wentian applauded happily.

"Khan, please distinguish the difference between scientific research equipment and toys." Kong Fanxi's mouth suddenly turned into an O-shape, and after hesitating for a while, he said: "Splitting matter to obtain nanomaterials may be interesting at first, but if you are asked to manually divide it a thousand times a day, you will find it very boring."

"According to you, the mentor wouldn't have asked me to perform 10,000 substance-splitting operations in the afternoon, would he?" Yang Wentian thought of the little boy who would also doze off while sitting, and an uneasy mood arose in his heart.

"Don't worry, now that there is a nanomaterial production equipment, you only need to do a demonstration action yourself, let the intelligent brain of the device record the action parameters during operation, and the intelligent brain can simulate your actions and repeat them constantly to make nanomaterials." Kong Fanxi smiled and stretched out an index finger to Yang Wentian and shook it.

"It's easy to have machines instead of people." After listening to the other party's supplementary explanation, Yang Wentian was relieved.

"Doing this demonstration action of dividing matter is not as simple as you think, which has become the key and hindrance to the development of nanotechnology." Kong Fanxi shook his head again and again and sighed, "There are different difficulties in dividing different substances, take the segmentation of carbon elements, a hundred years ago Huaxia scientists have been able to divide to 0.5 nanometers, and until now the world's public record is 0.43 nanometers, the theoretical limit of 0.4 nanometers, no country or individual has announced that it can do it."
