Chapter 435: Electrohydrodynamics Laboratory

Chapter 435
The original intention of the Institute of Mathematics and Physics at the University of Cambridge was to allow experts in the fields of mathematics and physics to devote a period of time to scientific research in addition to busy teaching tasks.
Most of the members in the institute undertake key projects of Yingguo Teaching Fund, general projects, youth science fund and other scientific research projects.
Over the past few decades, countless scientific researchers have done a good job during their stay in the institute. They have received various mathematics and physics supports and organized various international and domestic academic seminars. They have invited famous domestic and foreign mathematicians and Physicists come to give lectures and hold academic frontier lectures.
It can be said that of the 100 academic papers on mathematics and physics published by the University of Cambridge, it is estimated that 80 of them will come from the Institute of Mathematics and Physics of the University of Cambridge.
Unlike the small research office that Cheng Nuo spent at MIT, which was only supported by Professor Fresnel, the Institute of Mathematics and Physics at the University of Cambridge is made up of more than 100 researchers from all over the institute. , Has accumulated such a detached position.
Last year alone, the Institute of Mathematics and Physics completed more than 30 first-level scientific research projects under the Royal Academy of Sciences.
The research group that Director Alding sent Cheng Nuo to is one of the 100 first-level scientific research projects issued by the Royal Academy of Sciences at the beginning of this year.
The Institute of Mathematics and Physics has only four floors. Except for the fourth floor for office use, the other three floors are all large and small laboratories.
Unlike mathematics, where you only need to write calculations in a notebook, most physics research needs experimental data as support, so most of the entire three-story laboratory is a physics laboratory.
Although Alding is a member of the Department of Mathematics, he has not suppressed the influence of the Department of Physics since he was the director. Instead, he spent 80% of the annual funds for various physics research projects.
Compared with mathematics, the investment in physics research is terribly high.
To do math projects, you only need simple paper and pen, plus a computer at most.
The physical items can be different. If you want to do a subject, you must do experiments, and if you want to do experiments, you need to buy equipment.
A piece of experimental equipment may cost hundreds of thousands of pounds, but the more expensive ones can reach hundreds of thousands of pounds. The research fund granted by the Royal Academy of Sciences is not enough. It does not require the research institute to fund it.
If the experiment fails, it will be even more blood loss!
Now the research progress of a physics project in the institute is stuck, and a person from the mathematics department is needed to help. Alding had no idlers available, so he let Cheng Nuo, who had just joined the job, stand for a while.
Alding called Professor Clay and asked him to take Cheng Nuo to the physics group to report.
Professor Clay took Cheng Nuo to Lab 203 on the second floor.
The words "Electrohydrodynamics Laboratory" were written on the door plate.
Clay pushed the door directly and walked in.
The area of ​​the electrohydrodynamics laboratory is not large, about 100 square meters. After all, it is only a marginal subject between fluid mechanics and electrodynamics, and does not require super-large experimental equipment.
At this time, two professors were doing experiments in the laboratory.
The two were wearing white lab coats and stood in front of the tempered glass in the vacuum chamber. One was operating the instrument and the other was recording data.
In the vacuum chamber, the capillary nozzle heats and melts the Bi-Zn alloy. After the cathode and anode flashlight adjusts the intermediate distance, it releases a super voltage, and Cheng Nuo can see the pulsating electric sparks.
A research institute presses the button on the instrument to drive the nozzle of the crucible to spray a liquid stream. The dispersed liquid droplets are cooled during the descending process and fall onto the bottom of the cold trap.
The chassis was removed from the vacuum chamber by a robotic arm, and another research institute took a sample and observed it under an electron microscope for a while, then gently shook his head at the other person.
"Failed again." The tone was helpless.
Cheng Nuo and Professor Clay stood by and watched all this silently.
It was not until the two researchers turned around after finishing the experiment that they saw the two standing in the laboratory for a long time.
"Still failed?" Professor Clay frowned and asked the two of them.
The elder of the two researchers smiled bitterly, "Yes, we have revised more than 50 sets of data, but we still can't get the ultra-nano powder that meets the regulations."
"Do you know the reason?"
"We guessed that there was a problem with the calculation of the data. Then we asked the director to ask a mathematician to come and help us. How about, when will the director say the person will arrive?"
Professor Klay glanced at Cheng Nuo behind him, and a funny smile appeared on the corner of his mouth, "I have brought you people."
"Bring it? Where?" The researcher was stunned for a moment, then looked at Cheng Nuo, who was standing behind Professor Klein, with a sudden heart.
He laughed dryly, "Mr. Clay, what you said was not the one standing behind you."
Klay gave the researcher an appreciative look, "Yes, this one is the researcher the teacher just hired at a high price, Cheng Nuo!"
The two looked at the young and excessive Cheng Nuo, glanced at each other, and both shook their heads and smiled bitterly.
Professor Klay dragged Cheng Nuo to the front and introduced, "These two are Professor Alec Barnard and Professor Max Garrison, both of whom are physicists who have been famous for many years in the physics field and are experts in the field of mechanics. ."
"Good for you two." Cheng Nuo smiled.
Professor Clay explained to the two professors,
Two, don’t be fooled by Cheng Nuo’s looks. Although he is only a student, his level of mathematics is enough to solve the problems you are currently facing. The teacher has taken a lot of effort. So he agreed to come and help."
What, still a student? !
The two professors were too lazy to complain.
The director is because they experimented too many times and consumed a lot of resources, so let them go completely.
"Thank you for the kindness of the director," the two said with a pale face.
"I won't stay longer. The three of you will talk and try to finish the topic as soon as possible." After Clay finished speaking, ~EbookFREE.me~ then hurriedly left.
Only Cheng Nuo and the two professors were left in the laboratory with big eyes and small eyes.
"Huh!" The older researcher snorted coldly, turned his head to ignore Cheng Nuo, and walked to the desk to look at the large amount of experimental data in a daze.
The other researcher did not speak to Cheng Nuo either, and frowned in front of the instrument to wonder what was wrong.
Cheng Nuo was too lazy to speak, he was called to help, not isolated.
Pulling over a chair casually, Cheng Nuo leaned Erlang's legs and played with her mobile phone leisurely.
A few minutes later, the older researcher glanced at Cheng Nuo, who was playing a mini game with his mobile phone. After struggling for a few seconds, he took the lead to break the silence.
